THE CORPORATION OF DRINKING WATER QUALITY REPORT 215

A Message from the Manager June, 216 Providing high quality drinking water to Delta s residents and businesses is the focus of our water utility. A safe, clean and reliable drinking water supply is essential for a healthy and prosperous community. This annual Water Quality Report demonstrates the commitment by Regional and Delta staff to meet the goals of ensuring a high quality and sustainable water supply. Although the focus of our report is on water quality monitoring and reporting, which are an important component of the multi-barrier approach, the report also discusses the capital infrastructure replacement and operating and maintenance programs, which are equally important. Our ongoing water infrastructure replacement program seeks to proactively replace older mains that are reaching the end of their service life in order to prevent breaks, service disruptions and water quality problems, while the regular maintenance of valves, fire hydrants, pump stations and reservoirs provides for an effective and dependable water supply system. Delta staff work diligently to construct, operate and maintain the water distribution system and well water supply by Watershed Park. This annual report demonstrates our commitment to providing Delta with a safe and reliable water supply, today and for years to come. Harald Fograscher, P.Eng. Manager of Utilities

DRINKING WATER QUALITY REPORT 215 EXECUTIVE SUMMARY Delta has been producing an annual report about the health of the water distribution and supply system since 2. The 215 Drinking Water Quality Report fulfills the requirements of the British Columbia Drinking Water Protection Act by providing an overview of the water system, discussing individual component maintenance, describing the unique features of our system, and summarizing the results of the water quality testing program. Specifically, this report is produced to satisfy a requirement of the Drinking Water Protection Regulation, May 23, Section 11. In summary, Delta undertook the following works in 215: exercised over 5,6 flow control valves; maintained nearly 3,9 fire hydrants; flushed the entire water distribution system; maintained 4 pressure reducing stations; maintained three pump stations; maintained approximately 39 air valves; conducted 76 site investigations, initiated by residents, for water related questions/concerns; replaced approximately 4. kilometres of watermain with new mains of superior quality material and upgraded pipe diameters, if required, to provide required fire flows; collected and processed nearly 1,4 water quality samples from 34 test locations throughout Delta s water distribution system; conducted quarterly detailed physical and chemical analysis on Delta s well water; repaired 19 watermain breaks without compromising our system; and, saved approximately $45, by introducing water from the wells located near Watershed Park into our distribution system. We take our responsibility as a water purveyor seriously and proudly maintain a system that consistently meets the provincial requirements of the Drinking Water Protection Regulation and provides Delta residents and businesses with the highest quality drinking water available. We trust you find the information provided in this report to be of interest, and that it demonstrates our commitment to delivering this precious resource.

The average household would spend approximately $5 on water annually if purchased from a superstore based on current consumption rates. 1. SYSTEM OVERVIEW Approximately 97% of the water distributed in Delta is purchased from Metro Vancouver (MV). MV sources the water from the Capilano, Seymour, and Coquitlam Reservoirs. The water from these surface water sources can be directed to different areas within the municipality by a series of valves, pressure reducing stations, and pump stations. Delta receives the majority of its water from the Seymour watershed but can also receive water from Capilano and Coquitlam watersheds under certain conditions. The MV supplied water enters Delta from four submarine crossings: 1) the Lulu/Delta Main entering Ladner; 2) the Tilbury Main entering Tilbury; 3) the Annacis No.2 Main entering Annacis Island and continuing on to Surrey; and 4) the Annacis No.4 Main entering Annacis Island. Appendix 2 shows MV s distribution network while Appendix 3 lists the tie-in locations where the MV supplied water enters Delta s system. The other 3% of the water we distribute comes from our 3 artesian wells near Watershed Park. This water is pumped from deep wells in Sunshine Hills into the 64 Avenue Reservoir and then distributed to the lowland area south of 64 Avenue. As this system requires minimal pumping to get the water from the wells into the reservoir, and then relies on gravity to supply the area south of 64 Avenue, it is relatively inexpensive to operate.

2. MONITORING PROGRAM Drinking water quality is a function of source water quality, water treatment, and water quality changes after treatment. As a result, monitoring of drinking water quality consists of three components: source water monitoring, monitoring after treatment, and monitoring in the distribution system. As previously stated, approximately 97% of the water used within Delta is purchased directly from MV, which carries out source water testing and testing after treatment. The parameters and frequency for testing MV water is shown in Appendix 4. The then tests the MV water at various locations within the local distribution system. In addition, Delta is in a unique position in that we supplement water into the distribution system from 3 artesian wells. The test parameters for this water, which originates from a confined aquifer at a depth of approximately 7 metres, are much more detailed. The well water testing parameters are attached in Appendix 6. 3. TESTING PARAMETERS The, as a purveyor of drinking water to a population of roughly 1,, is required to test a minimum of 9 samples per month, as outlined in the Drinking Water Protection Regulation. Delta s water distribution network is comprised of approximately 596 kilometres of watermain, and supplies water to five distinct geographical areas; North Delta, Ladner, Tsawwassen, Tilbury and Annacis Island. To adequately represent all areas within our network, an average of 115 samples are tested per month; 25 more than the guideline suggests. The 34 sites shown in Appendix 1 are sampled on a weekly basis and tested for microbiological characteristics; specifically, total coliforms, E.coli, heterotrophic plate counts, and turbidity. Samples are also tested for aesthetic objectives, temperature, and ph level. As it is not feasible to test directly for all pathogens in the drinking water, microbiological guidelines are based on indicator organisms outlined in the test parameters. A Maximum Acceptable Concentration (MAC) level for each specific test parameter has been established by Health Canada s Guidelines for Canadian Drinking Water Quality (GCDWQ). Each MAC has been designed to safeguard health, assuming a lifelong consumption of drinking water containing the substances at the maximum concentration level. Aesthetic Objectives (AO s) apply to characteristics of drinking water that can affect its acceptance by consumers. These would include items such as taste, odour, and appearance. Some AO s, such as turbidity, could pose a health risk to some at risk consumers if the MAC levels are exceeded. 2

3.1 Test Parameters 97% of the world s water is saline. Another 2% is ice (glaciers). That leaves 1% of the water available for drinking, community needs, agriculture, and industry. Total Coliforms The presence of total coliforms in the water system is an indicator that the system is experiencing microbial re-growth, that infiltration has occurred, or that water has not been properly treated at the source. The GCDWQ states that no consecutive samples from the same site or not more than 1% of samples should contain the presence of total coliform bacteria. If a sample tests positive for total coliform bacteria, it is resampled to confirm the original result. If the second test result is positive, the affected main is flushed, monitored, and tested again. The response to another unacceptable test result is to take the main out of service, chlorinate, flush, retest, and keep it out of service until acceptable results are obtained. E.coli Escherichia coli is one species in the fecal coliform group, and the one best known because of its link to the death of seven people and illness of over 2 others in Walkerton, Ontario. This bacterial species is a definite indicator of the presence of feces in the distribution system. The MAC for E.coli is per 1 ml. A confirmed unacceptable MAC test for E.coli can trigger an immediate boil water order by the Environmental Health Officer which remains in effect until the problem is isolated, identified, resolved, and acceptable test results are obtained. The Drinking Water Protection Regulation Schedule A, shown below in Figure 2, has established the following microbiological criteria: Parameter: Fecal coliform bacteria Standard: No detectable fecal coliform bacteria per 1 ml Escherichia coli (E.coli) No detectable Escherichia coli per 1 ml Total coliform bacteria: (a) 1 sample in a 3 day period No detectable total coliform bacteria per 1 ml (b) More than 1 sample in a 3 day period At least 9% of samples have no detectable total coliform bacteria per 1 ml and no sample has more than 1 total coliform bacteria per 1 ml Figure 2: Water Quality Standards for Potable Water. 3

Heterotrophic Plate Count Less than 1% of water treated for potable use is consumed. The rest is put down the drains and into the sewerage system for treatment. The general bacterial population is estimated by means of a background colony count referred to as a heterotrophic plate count (HPC). Although not a significant health concern on its own, the presence of a background bacterial growth indicates that pathogenic bacteria could thrive in the system should they be able to enter it. Also, excessively high HPCs can hinder the detection of coliforms. No MAC is specified for HPC bacteria in water supplied by public drinking water systems. Instead, increases in HPC concentrations above baseline levels are considered undesirable. Delta s baseline level for HPCs is 5 colonies per millilitre (ml). If a test result indicates more than 5, the water is resampled and tested. Further test results indicating HPCs above 5 require the watermains to be flushed and monitored until a decreasing trend is observed. Turbidity Turbidity measurements relate to the optical properties of water. Suspended matter such as clay, silt, finely divided organic & inorganic matter, soluble coloured organic compounds, plankton, and other microscopic organisms all contribute to poor turbidity levels. Excessive turbidity not only detracts from the appearance and taste of water, it can also serve as a source of nutrients for waterborne bacteria and a surrogate for pathogens. As Delta s MV supply source is surficial, and therefore subject to changes in quality due to weather changes, the water is sometimes discoloured and may taste different following a period of heavy rain after a long dry spell. Excessively high turbidity can also have a negative effect on disinfection techniques. Turbidity tests measure the scattering and absorbing effect of suspended particles on light which is measured in nephelometric turbidity units (NTU). The GCDWQ states that for filtration systems the turbidity levels should be as low as reasonably possible with a target of less than.1 NTU. However, Delta tests only within the local distribution system and the Aesthetic Objective (AO) has been set at <1 NTU at the point of consumption. The system is monitored and flushed, if necessary, when unacceptably high turbidity test results are recorded. ph The ph of water can influence the formation of disinfection by-products and the effectiveness of treatment. An acceptable ph range for drinking water is 6.5 to 8.5. Chlorine Residual Chlorine is used as a disinfectant by MV. The purpose of maintaining a disinfectant residual in both MV s and Delta s distribution system, also known as free chlorine, is to control the re-growth of bacteria. Observing a chlorine residual of approximately.4 to.7 milligram per litre () in Delta s system is normal. However, the target minimum concentration is.2, with the exception of Delta s well water service 4

area which is a non-chlorinated supply. Delta s well water supply is monitored closely, and if required a back up chlorination injection system is available. Disinfection By-products Reactions between chlorine used for disinfection and dissolved natural organic matter in the water can result in the formation of two major families of potentially carcinogenic by-products: Total Trihalomethanes (TTHMs) and Total Haloacetic Acids (THAAs). The Guideline for Canadian Drinking Water Quality states that the MAC for TTHMs and THAAs in drinking water is.1 (1 parts per billion) and.8 (8 parts per billion), respectively, based on a locational running annual average of a minimum of quarterly samples. Metals The limits for tested metals are listed in Appendix 5 (Physical and Chemical Analysis of Source Supply). Vinyl Chloride Vinyl chloride, a synthetic chemical, can enter drinking water through leaching from polyvinyl chloride (PVC) pipes due to the biodegradation of synthetic solvents. The MAC for vinyl chloride is.2. 4. TESTING PROGRAM Water at 34 test sites in Delta is sampled and tested weekly by our Water quality Technician. Samples are tested on-site for temperature, ph, turbidity, and chlorine residual. An additional sample is taken, in accordance with the 2th Edition of Standard Methods for the Examination of Water and Wastewater, placed in a sterile bottle, sealed, identified by location with time of day noted, and placed in a cooler. At the end of each day the samples are sent to the MV laboratory where the water is tested for ph, turbidity, chlorine residual, total coliform, E.coli, and heterotrophic plate counts. The MV laboratory is a member of the Standards Council of Canada and is an accredited laboratory within the Canadian Association of Environmental Analytical Laboratories. Results are reported to Delta s Water Quality Technician within seven days of submitting the samples. However, preliminary E.coli tests are reviewed within 24 hrs and are reported immediately should a positive result occur. Appendix 1 details the reporting procedure should a positive E.coli test be indicated. Supplementary to our weekly testing of the MV water within our distribution system, there is a quarterly testing program on the water from the three wells that contribute to Delta s water supply. The test parameters are shown in Appendix 6, and Exova Labs, a laboratory accredited by the Canadian Association of Environmental Analytical 5

Laboratories and by the Standards Council of Canada, conducts the tests, for which the results are shown in Appendix 7. Figure 3: Delta Water Quality Technician sampling water at 88 Street Auto Flushing Unit The measures taken to ensure the health of our water system are taken very seriously. The s staff has worked closely with Fraser Health to ensure we have a program in place that meets, and even surpasses, the conditions set out in the Water Monitoring Protocol. We sample and test more sites than required, conduct more thorough and more frequent tests of our well water source than required, and have installed sampling stations to provide an accurate overview of the health of our drinking water system. When our water sampling van is in the neighbourhood, it is confirmation that we are doing whatever we can to provide our residents with safe and healthy drinking water. 5. WATER DISTRIBUTION SYSTEM DETAILS Delta s water system services an area of approximately 18,1 hectares including North Delta, Tsawwassen, Ladner, Tilbury, Annacis Island, Delta Port, Boundary Bay Airport, and the BC Ferry Terminal. The distributes water in pipes made of a variety of materials. The first watermains were installed in 199 and were made of wood. These wooden mains have long since been replaced and new mains constructed with other material such as cast iron, ductile iron, polyvinyl chloride (PVC), polyethylene, steel, asbestos cement, and copper. 5.1 Watermains Cast Iron Watermains Approximately 2%, or 12 kilometres, of Delta s watermain inventory consists of cast iron pipe. The majority of this pipe was installed prior to 1978. The life expectancy of cast iron pipe is between 5 and 7 years, depending on the corrosiveness of the soil. 6

When you go to a restaurant and they give you that complimentary glass of water, remember, it takes another 2 glasses to wash it. Decline it if you do not plan to drink it. Watermain break records indicate that 13 watermain breaks occurred in the cast iron inventory in 215. Ductile Iron Watermains Approximately 1%, or 6 kilometres, of Delta s watermain inventory consists of ductile iron pipe. While most ductile iron pipe was installed between 1969 and 1988, it is still used for some applications. The current Delta Construction Standard requires cathodic protection on all new ductile iron pipe installations, increasing the service life expectancy to 1 years. There were three watermain breaks in the ductile iron inventory in 215 as a result of corrosion. PVC Watermains Approximately 53%, or 318 kilometres, of Delta s watermain inventory consists of PVC pipe. The majority of this pipe was installed since 1979. Although the service life of PVC pipe has not yet been demonstrated, 75 years is estimated. There were no PVC watermain breaks in 215. Steel Watermains Approximately 1%, or 8 kilometres, of Delta s watermain inventory consists of steel. These mains are large diameter and are primarily used as transmission mains. A break to one of these mains could have serious results as the volume of water released prior to isolation could be enormous. Also, some of these mains serve large areas of Delta and disruption to them could leave entire areas without water. Corrosive soils in Delta can greatly affect the life expectancy of the steel mains. To compensate, zinc bars, called anodes, are attached to the main in an effort to protect the steel pipe. As most of these mains were constructed in the 197 s they are beginning to reach the end of their service life. No watermain breaks occurred in the steel pipe inventory in 215. Asbestos Cement Watermains Approximately 13%, or 78 kilometres, of Delta s watermain inventory consists of asbestos cement pipe. Most of this pipe material was installed prior to 1978. The life expectancy of asbestos cement pipe is between 5 and 6 years, depending on soil type and ground conditions. Workers repairing or replacing asbestos pipe are required to take special safety precautions. Watermain break records indicate that three watermain breaks occurred in the asbestos cement inventory in 215. Two were caused by holes while a third resulted due to a cap being blown off the main. High Density Polyethylene Watermains Approximately 2%, or 9 kilometres, of Delta s watermain inventory consists of polyethylene pipe. This pipe material has only been in use in Delta since 2 and is mainly used for transmission mains or in specific applications. The construction method for polyethylene pipe is unique in that the pipe sections are joined together 7

by fusion welding. This method of pipe joining provides for leak tight joints and greater seismic resistance. Although the service life of polyethylene pipe is not yet known, 75 years is estimated. There is also approximately 1%, or 3 kilometers of watermains made from other materials.

If a pumping station or storage facility were to fail, water service to a large area of the community could be discontinued or adversely affected until repaired. Each pump station has a service life of approximately 4 to 5 years. 8

Don t leave the water running when you brush your teeth or shave. A tap runs at approximately 2 litres per minute. If it takes 1 minutes to shave in the morning and 3 to brush your teeth, that s about 26 litres of water used. Figure 5: Pump Station on 4 Avenue at Pebble Hill Reservoir Water Services Delta has approximately 31,7 water service connections supplying water from our distribution network to individual property lines. As with Delta watermains, these pipes age and require replacement. If a service connection were to fail, water service to the affected home or business would be discontinued until repaired. Whenever possible, service connections older than 25 years are replaced by the developers as part of their Building Permit, as required in Delta s Subdivision & Development Standards Bylaw. Service connections are also replaced at the time of watermain replacement, under Delta s Capital Plan. Of the approximate 31,7 service connections approximately 8% are copper, with some installed as early as 194. Based on a study by the Seattle Water Department, the average service life for copper service pipes installed in Seattle is 4 to 5 years. The corrosive nature of Delta s soils will likely decrease the average service life to 3 to 4 years. The remaining 2% of service connections are comprised of cast iron, asbestos cement, ductile iron, PVC, or polyethylene pipe. The older industrial service pipes are made of asbestos cement and cast iron pipe, while the newer industrial service pipes are made of ductile iron, PVC or polyethylene. Water Storage Facilities Two of the three water storage facilities in Delta are owned and operated by MV; namely Pebble Hill Reservoir in Tsawwassen and Hellings Reservoir in North Delta. The 64 Avenue Reservoir, with a capacity of 7,5, litres, is owned and operated by Delta and is primarily filled with water from Delta s artesian wells. The current reservoir structure was built in 1959 and is nearing the end of its service life. The 9

reservoir is a key facility for water supply to East Ladner, and also plays a vital role in providing an emergency water supply. Figure 6: Water reservoir and pump station on 64 Avenue In April of 216 Delta applied for a $6 million grant from the New Building Canada Fund to construct a new reservoir at the 64 th Avenue site by Watershed Park, shown above in Figure 6. The upgrade would include the construction of a pump station, new discharge piping, and groundwater well. This improvement project would address the seismic concerns of the current facility. Fire Hydrants Delta has approximately 3,88 fire hydrants, some installed as early as the 195's. The older style slide-gate hydrants, which are less efficient at providing water for fire protection, are being replaced with new compression-style hydrants that provide more flow at a higher pressure. However, approximately 19% of the hydrant inventory is still the slide-gate hydrant style. When a slide-gate hydrant has reached the end of its service life or a watermain is being upgraded as part of the Capital Program, slide-gate hydrants are replaced with compression hydrants. Pressure-Reducing Valve-Stations Delta has 4 pressure reducing valve stations containing approximately 75 pressure regulating valves (PRVs). Twenty-two of these stations are connected to the MV water supply system while the remaining 18 are internal to Delta s water system. Delta recently relocated two existing below grade PRV stations to above ground structures: 12 th Avenue PRV (Figure 7) Highway 17 and 52 Street PRV Pressure reducing valves are used to step-down the pressure in Delta s water distribution system to an acceptable supply pressure. 1

To see if your toilet is leaking, put a few drops of food colouring in the tank. Wait a few minutes, if the water in the bowl colours, you know you have a leak. Remember to fix it after you find it. Figure 7: 12 th Avenue PRV Station Fluctuating pressures can place excessive stress on plumbing systems and watermains. Delta currently overhauls the PRV stations every five years in an effort to extend their service life to fifty years, and replaces others that are near the end of their service life. Flow Control Valves Delta has approximately 5,69 flow control valves in the water distribution system. The valves are primarily used to isolate areas of the network for inspection or repair. If a valve were to fail, water flow to the affected main would be disrupted until repaired. The expected service life of a flow control valve is 4 to 5 years without cathodic protection, and 1 years with cathodic protection. Air Valves Delta has approximately 393 air valves, installed in below-ground chambers, which bleed air from the pressurized system through piping that discharges above grade. Entrapped air in the distribution system could impact water flow. Air valves receive maintenance as required and are replaced at the end of their service life, which is approximately 2 years. Backflow Prevention Assemblies Delta has taken a proactive approach in protecting the water distribution system from harmful cross connections. The Engineering and Plumbing Departments have had a municipal wide Backflow Prevention Program in place for several years. Section 15 of the British Columbia Drinking Water Protection Regulation outlines that an assessment response plan must include provisions to identify, eliminate and prevent cross connections with non-potable water sources. In addition, Part 5 of the Delta Waterworks Rates and Regulation Bylaw no. 7441, 216 (April 4, 216) also contains regulations that prevent contamination. 11

For instance, the Bylaw states that: When you water your lawn for hour, approximately 1,2 litres of water is consumed. 36) No person shall, except as authorized by the Director under section 39, connect or cause or allow to be connected to the water supply facilities on any premises any piping, fixture, fitting, or other appurtenance that would in any circumstances permit water, wastewater, or any other liquid substances to enter any part of the Waterworks System, including that Person s Water Service. Within the municipality, there are approximately 3,81 backflow prevention assemblies currently in service. All testable backflow assemblies must be tested annually. Delta s inventory can be broken down as follows: Double Check Valve Assemblies (DCVA's) 2,51 Reduced Pressure Backflow Assemblies (RPBA's) 1,2 Pressure Vacuum Breaker Assemblies (PVBA's) - 1 Most of these assemblies are privately owned and all assemblies are required to be tested annually. They can be installed at the point of hazard, or in premise isolation. In either case, a properly maintained backflow assembly prevents non-potable water, or spent water, from entering the potable water system by means of backsiphonage or backpressure. Water Meters Delta currently meters approximately 4,663 water services, or approximately 15% of all water connections to homes or businesses. All new construction, including residential, secondary suites and agricultural properties require a water meter, while our Volunteer Water Meter Program continues to be available to residents where a meter is installed at no charge to the homeowner. As a water meter ages, its mechanisms tend to underestimate the water passing through it and users are undercharged for water use. The service life of a water meter is approximately 15 years. Auto Watermain Flushers Delta has installed auto flushing units at nine locations that have experienced higher than normal heterotrophic plate counts (HPC s) in the past. These units automatically flush the watermains at regular intervals to ensure water quality is maintained. A photograph of one of the units is seen in Figure 3. 5.3 Water System Value The total value of our water distribution system, as detailed in Figure 8 below, is approximately $46 million. The spends approximately $6 million per year on water infrastructure replacement. The replacement program is designed to address some of these previously discussed deficiencies within the system 12

on a priority basis. However, a thorough and comprehensive maintenance program helps to extend the life expectancy of some of these water infrastructure components.

SYSTEM MAINTENANCE Figure 8: Infrastructure replacement value, 215 dollars Maintenance of the Delta water system involves five key programs: valve exercising, watermain flushing, hydrant maintenance, well maintenance, and reservoir maintenance, as detailed on Figure 9 below. As replacement of the entire distribution network is not affordable, system maintenance becomes a critical component in the management of the water infrastructure. Delta expends approximately $2.5 million annually on water system maintenance. 6.1 Annual Maintenance Program Program Ja Fe Ma Ap Ma Jn Jl Au Se Oc No De Valve Exercising Watermain Flushing Hydrant Maintenance Reservoir Maintenance* * *as required Figure 9: Delta water maintenance program Note that the watermain flushing schedule is impacted by seasonal water sprinkling restrictions. 13

A tap that drips 2 tablespoons per minute equates to 2,6 litres of wasted water in one year. All water that goes down the drain ends up at the Annacis Island Waste Water Treatment Plant. Valve Maintenance Valves are interspersed along watermains and can be closed or opened to alter the flow of water. These valves can be buried or left closed causing maintenance challenges by restricting water flow through the main. In response to this issue, Delta staff commenced a valve exercising program in 1985. Each valve is inspected annually, exposing buried valves, making repairs, and exercising every valve by turning it first to a closed position and then back to open. This process begins in January and lasts for approximately six weeks. When the watermain flushing and hydrant maintenance programs are completed in September, the valves are checked to ensure all valves are open to ensure an uninterrupted water supply. Watermain Maintenance Watermain maintenance involves repairing damaged or leaking watermains, and ensuring that watermains are operating effectively. Watermain Upgrading In addition to repairing watermains, Delta replaces aging watermains as a preventive measure. An ongoing annual replacement program is in place, and targets areas with older piping materials in susceptible conditions, areas of inadequate fire flow, and neighbourhood rehabilitation sites. Watermain Flushing Delta is at the southern extreme of long transmission mains coming from the Seymour, Capilano, and Coquitlam Reservoirs. As water travels from the watershed, it transports sediment into Delta s water distribution system. In addition to accumulated sediment, some areas of the water system are susceptible to water stagnation where water usage is low or watermains terminate at a street ends. Sediment and stagnation can create an undesirable level of turbidity in the water. As discussed earlier turbidity impacts aesthetic quality and promotes bacterial growth. In response to these concerns, Delta initiated a watermain flushing program in 1985. Each main is flushed annually, during daytime hours. When flushing, a hydrant is opened causing the increase in water velocity within the main which initiates the removal of sediment. Large distribution mains, such as those found on Ladner Trunk Road, 56 Street, Scott Road, and River Road, are not flushed because velocities through these mains are routinely high enough to effect a scouring action that moves sediment and prevents water stagnation. There are a number of locations throughout Delta referred to as trouble spots where water demand is low or where watermains terminate in a dead end. These areas are flushed as required, sometimes as often as every two months. When opportunities arise, either through new development or 14

capital upgrades, the water system is looped. Delta also flushes mains within 24 hours of receiving test results from the MV Laboratory that indicate bacteria levels outside the acceptable provincial water quality guidelines. Hydrant Maintenance Figure 1: Fire hydrant undergoing regular annual maintenance Historically, fire hydrants were only serviced when requested by the Fire Department. To ensure proper fire protection, Delta implemented a fire hydrant maintenance program in 1985. The program checks the pressure on each hydrant before it is serviced and dismantles, renewing worn parts as necessary. The hydrant is then lubricated and reassembled. This program takes approximately four months to complete. Reservoir Maintenance Debris can accumulate in reservoirs and bacteria and algae can grow on the walls. Delta services the 64 Avenue Reservoir when required. Prior to 2, the program typically involved decommissioning of the reservoir, draining it, removing sediment, repairing leaks, and disinfection. The reservoir was then refilled and tested for water quality. This program required approximately two weeks to complete before the reservoir could be brought back into service. When the 64 Avenue Reservoir was cleaned in September of 2, no sediment build up was observed. Prior to well water being introduced to the reservoir, it was normal to observe approximately 1 millimetres of sediment build-up, which would then be removed. The water fed to the reservoir from the three wells contains almost no sediment. This has eliminated the requirement for annual reservoir cleaning, and is now scheduled only when required. Cleaning is performed with a team of divers vacuuming silt from the bottom of the reservoir, which eliminates the need for draining the reservoir and reduces maintenance costs. The Pebble Hill and Hellings reservoirs are owned and maintained by MV. 15

Water Well Maintenance Roughly 6% of a typical family household water footprint is from lawn and garden maintenance. Rain barrels, sustainable gardens, and lawn watering restrictions can greatly reduce this consumption. Well maintenance is a critical component of our water infrastructure maintenance program. As the water from the wells is introduced into our distribution network untreated, we conduct daily maintenance and monitoring. The water levels are measured and recorded daily to ensure the aquifer is not over utilized and the system checked for malfunctions. In addition, the three wells are redeveloped every three to five years which involves surging, jetting, and treating the wells with biodegradable product applications. This helps maintain production rates, and avoids the costly alternative of replacing a well. Figure 11: Well #1, Watershed Park wells All activities in the well compound area are closely monitored and regulated. Staff who maintain this facility are certified by the Environmental Operators Certification Program of B.C. 7. WATERMAIN BREAKS Most water utilities frequently experience minor disruptions. Pipes break, valves stick, hydrants leak and power outages occur. Although these are not anticipated, they can usually be corrected with minimal disruption, and regular service can be quickly restored. In 215, our staff responded to and repaired 19 watermain breaks, or leaks (Figure 12). Eleven watermains were split failures around the pipe, 5 had holes, one had a leaking joint, one had a cap blown off the main (likely corrosion), and one was due to pipe corrosion. 16

To prevent a possible introduction of contamination, our crews try to maintain positive pressure in the system. This practice makes the repair more difficult, but it is a necessary safeguard to protect the integrity of our system. Repairs or Tie-ins with No Groundwater Entry These repairs are typically the result of electrolysis holes, cracks, splits, and are repaired using repair clamps. Provided the watermain maintains positive pressure until our crews have excavated below the invert of the pipe, it is assumed that no contaminant can enter the system. The repair clamps and other materials required to complete the repairs are cleaned with a 6% chlorine solution. Upon completion of the repairs the main is flushed and put back into service. Repairs or Tie-ins with Groundwater Entry On occasion, breaks have occurred where it is not possible to maintain positive pressure or to pump the groundwater below the invert of the watermain before throttling the main down or shutting it off. In this case, disinfection, flushing, and residual testing procedures are followed prior to re-commissioning the watermain. Our staff adhere to the procedures set out in the American Water Works Association Standard C651-92 regarding watermain chlorination, that in summary requires: that the main is completely isolated, it is disinfected with a chlorine concentration of 2 milligrams per litre for a retention time of two hours, and that after two hours the chlorine residual level is a minimum of 1. If this condition is not met, the main must be re-chlorinated using the same standard. After a successful result, the watermain is flushed continuously until the chlorine residual is less than one milligram per litre. When the desired residual level is achieved the main is put back into service. 17

E.coli Detection In Metro Vancouver about 34 liters of water per household are used each day. The major use of indoor residential water consumption is flushing the toilet. If E.coli are detected, that section of main is shut down until disinfection and proper re-testing is completed. The Fraser Health Authority is notified of any positive E.coli test. Waste Water Contamination Where a watermain break is accompanied by a sanitary sewer break, the watermain is throttled to maintain positive system pressure while the sanitary main is repaired. Once the sanitary main is repaired, the watermain is taken out of service, disinfected, flushing, and tested. The Environmental Health Officer is notified and the main is not put back into service until acceptable test results are achieved. Figure 13: Hellings Reservoir which is owned and operated by MV, and supplies North Delta 8. NOTIFICATION PROTOCOL Normally, breaks or disruption to water service are caused by conditions that can be repaired and reinstated directly by Delta crews without risk to the public health. Sometimes however, situations arise that require extra care to guarantee the infrastructure integrity. To confirm we have acted in an appropriate manner when addressing these abnormal occurrences, the notification protocol, as shown in Appendix 1, is followed. It describes the proper procedure to activate emergency water supply, repair watermain and water service breaks, and provide backup power to pumping stations during a power outage. It also includes a list of personnel to be notified, and flow charts of response procedures in case of emergency events. Fraser Health has requested that they be notified via email of watermain breaks. This procedure has been implemented for mains larger than 1mm in diameter. 18

9. UNIQUE CHARACTERISTICS OF SYSTEM Delta Water Source The redevelopment of two wells and construction of a third well near Watershed Park has provided Delta with an emergency drinking water source. Also, by introducing this water into the distribution system Delta offsets the rising cost of purchasing water from MV. This year, pumping from these wells resulted in savings of approximately $45,. As well-water production is steadily decreasing over time, the proposed 64 Avenue Drinking Water Storage and Supply Improvement project would include the development of a new groundwater well to restore production to past capacity. Delta has been receiving filtered Seymour source water from MV s Seymour-Capliano Filtration Plant since 21. This has significantly reduced the turbidity results in our water system, and improved our chlorine residual results. The Capilano source water is now also filtered at the filtration plant, further improving Delta s drinking water quality. Delta Water Source History In the spring of 1997 MV s transmission main broke beneath the Port Mann Bridge leaving only two alternate supply sources to Surrey and Delta. This event left Delta with greatly reduced system redundancy. To compensate for the reduced supply, a ban on sprinkling was mandated and other conservation measures implemented. Figure 14: Original well pump house, Watershed Park, constructed 196 Recognizing Delta s vulnerability, Council directed the Engineering Department to come up with an alternative water source to be available in the event of a natural catastrophe. Four water wells in Watershed Park, which supplied the lower Sunshine Hills area, had been abandoned some 25 years prior, but the buildings and infrastructure, although overgrown and in need of repair, were intact. After a thorough evaluation had been conducted, it was recommended that only two of the 19

Per capita water consumption in Delta has been decreasing steadily since 199. 1 9 8 7 Water Consumption L/capita/day original wells (#1 & #3) should be refurbished and that a new well (#5) should be constructed. As work to refurbish the wells was underway, it became apparent that the water from the aquifer was of a very high quality. Tests showed that it surpassed all conditions set out in the Guidelines for Canadian Drinking Water Quality, Sixth Edition. As a result, it was decided to introduce this water into our distribution system via the 64 Avenue Reservoir. A water tanker load out facility was also constructed to facilitate the distribution of well water to various locations in the case of a major emergency which would restrict water from MV sources to Delta. In 212, a drinking water station utilizing well water was constructed for use of park patrons. 6 5 199 1995 2 25 21 215 Water Consumption Figure 15: Watershed Park Drinking Water Station, constructed 212 Delta is the second highest per capita water user of all the MV member municipalities according to Metro Vancouver s 214 Water Consumption Statistics. Delta consumes an average of 614 litres per capita per day (including ICI) which is approximately 35% higher than the regional average. The main causes of this higher per capita consumption include large water-intensive industrial and agricultural operations. In 2 Delta implemented a leak detection program to determine the extent to which our distribution network could be contributing to the high consumption. Initial results indicate that although some leakage is occurring in areas where the service pipes are older, it does not appear to contribute in a significant way to the high average. In an effort to better understand water use in the agricultural areas and the equity of water usage, Delta metered all agricultural properties in 29. In addition, water meters are currently being installing on all legalized secondary suite properties. 2

1. TEST RESULTS Delta conducts its own well-water analysis to ensure the quality of the source water being introduced into the distribution system. Sampling sites DmDel 35 (Watershed Park Well #1), DmDel 36 (Watershed Park Well #5), and DmDel 37 (Watershed Park Well #3), were sampled by Delta Water Technicians and tested by Exova Labs. The extensive test parameters for this well-water analysis are outlined in Appendix 6. Sampling stations DmDel 22, 225, 38, and 329 (Watershed Park Reservoir), which are directly downstream of the wells were also scrutinized against the same parameters. No samples were found to exceed the MAC s as outlined by the GCDWQ. Complete records of all four quarterly tests are found in Appendix 7. Approximately 1,4 samples, collected weekly from 34 sites, were used to test for microbiological presence in Delta s local distribution system. The microbiological parameters that were tested are discussed below and complete test results are provided in Appendix 8. Quarterly and bi-annual testing of disinfection by-products, trace metals, and vinyl chloride from select sampling sites is also discussed in the subsequent section. Full test results are attached in Appendices 12, 13, and 14 respectively. Note that there were some changes to Delta s sampling sites throughout the year. The use of sample site DmDel 315, located at 276 41B Street, ended in March and a new site, DmDel 392, located nearby at 344 41B Street was used to collect data for the remainder of the year. This move was necessary to bring the sampling station onto Delta property. In addition, DmDel 327 located at 1145 84 Avenue was removed in September as part of the North Delta Recreation Centre expansion project. A replacement site is scheduled to be established within the area. DmDel 228 experienced poor test results due to a malfunctioning nearby air valve and general poor location of the sampling station location. The sampling station has since been relocated and the air valve replaced, as well as auto-flush unit installed. The impact of this malfunction is discussed further along in the report. Total Coliforms Parameter Guideline: At least 9% of samples have no detectable total coliform bacteria per 1 ml and no sample has more than 1 total coliform bacteria per 1 ml Two sites tested positive at least once for total coliforms (DmDel 221 and DmDel 228), however subsequent testing confirmed a safe water supply. Specifically, DmDel 221 at 482 42A Avenue tested 1 MF/1 ml on June 9 215. The site was then retested the following day which tested negative for total coliform cultures, which then qualifies the water as safe under the GCDWQ. The second sample site of note was DmDel 228 located at 663 Cabeldu Crescent. The table below describes the consecutive emergence of coliform counts at this site during the month of July 215. 21

The testing station and air valve were replaced and all 18 subsequent tests returned negative for the presence of total coliforms. E.coli Parameter MAC: MF/1 ml Of the nearly 1,4 samples analysed from 34 different sites for microbiological criteria, no E.coli bacteria was detected in Delta s water system. Heterotrophic Plate Counts Parameter Guideline: < Delta s baseline level of 5 colonies/ml Only three samples indicated elevated Heterotrophic Plate Counts; DmDel 327, DmDel 391 and DmDel 228. As mentioned earlier, there was an issue with the data taken at site 228 during the summer which makes the single problematic sample unrepresentative of the water quality and can be discounted. As for site 327 and 391, a contributing factor to high HPC counts at these locations may be the slow turn-over rate of water at low flow locations, such as dead ends. The new Seymour-Capilano Filtration Plant has reduced turbidity at the source, resulting in lower and less frequent HPC results at these locations. Test results of HPC s are shown in Appendix 8. The Heterotrophic Plate Counts in Delta s water system are considered safe despite the three outliers. The figure below shows average and maximum HPC at each sampling station over the course of the year. Dates for specific tests that exceeded HPC guidelines are marked on the graph. 22

There were 2 instances of high turbidity. The first was a reading of 3.8 NTU on December 15 th at DmDel 223, and the second was 3.3 NTU on March 24 th at DmDel 323. As seen below in Figure 18 below, these occurrences match turbid events observed by MV at the water source itself. Due to the heavily forested and steep geographical topography of the Seymour-Capilano watershed, the reservoirs are susceptible to spikes in turbidity during severe rainfall events. Flow balancing between filters while the new Seymour-Capilano twin tunnels were commissioned early in the year was also identified to be a cause of unusually high turbidity. Consequently, the rare and isolated events of high turbidity did not comprise the quality of Delta s drinking water. 23

There were only a small number of occurrences where single samples had a ph slightly outside the acceptable range out of the nearly 1,4 samples tested. No sample site ever tested outside the acceptable range more than once. In addition, these samples were never out-of-range by more than 1 ph level. The results are summarized in the figure below. 9 8.5 8 7.5 7 6.5 6 5.5 5 ph at Sampling Stations Sampling Station Average ph Max Allowable Min Allowable Figure 19:Average ph at sampling stations 24

Free Chlorine Residual Parameter Guideline: >.2 Test results for free chlorine residual are shown in Appendix 8, while Appendix 9 provides average free chlorine residual results, including a map indicating sites where samples consistently tested less than.2. This typically includes stations that are downstream of the well water source where there is some mixing with Metro Vancouver water. As such, low chlorine residual results are expected. Stations DmDel 35, 36, 37 generally have zero chlorine residual as this water originates from Delta s artesian wells, and is not chlorinated. Disinfection By-products Parameter MAC: 1 ppb for Total Trihalomethanes; 8 ppb for Total Haloacetic Acid Results of tests performed for disinfection by-products are summarized in Appendix 12. The levels of TTHMs and THAAs have reduced since construction of the Seymour- Capilano Filtration Plant and subsequent reduction of chlorine required for disinfection. All results were below the maximum allowable limit. Metals Parameter MAC: see Appendix 13 A total of eight samples were collected from four locations and tested biannually by Metro Vancouver for the presence of metals. The results of these samples are summarized in Appendix 13, and all are below the relevant guidelines. Vinyl chloride Parameter MAC:.2 As approximately 5% of Delta s watermain inventory consists of PVC pipe, six sample locations with predominantly PVC pipe were selected for testing of vinyl chloride. Each location was tested once in June and once in October. Out of the 12 samples taken, all vinyl chloride results were less than.1, well below the GCDWQ maximum acceptable concentration of.2. The test results are summarized in Appendix 14. 25

11. PUBLIC INQUIRIES staff responded to approximately 76 requests in 215 to investigate water related issues. More than half the calls received were in regard to low pressure, and in most instances the problems were determined to be related to residential or commercial plumbing systems. When calls regarding the potability of the water are received, The s Water Quality Technician takes a sample of the water in question and submit it to the MV Lab for testing. For all instances in 215, the test results confirmed the water met the appropriate guidelines for potable water in British Columbia. Issues: Number: Water Quality - Turbidity 23 Water Quality Smell Water Quality Taste Low Pressure / No Water 53 TOTAL: 76 12. CONCLUSION Figure 2: Public inquiry table The majority of all water consumed in Delta is purchased from Metro Vancouver. As with all surface water sources, the water quality can be inconsistent. Following significant rain events, turbidity levels can be higher than normal and, as a result, the treatment process can be inconsistent. Currently, Delta is benefiting from improved water quality from the Seymour-Capilano Filtration Plant, as can be observed from previous troublesome areas in Delta s system that are showing lower turbidity and HPC values, and higher, more stable, chlorine residuals. Furthermore, maintenance and monitoring programs are designed to meet the challenges of distributing this water in a way that does not compromise the health of our residents. In 215 nearly 1,4 water samples were collected in order to confirm a safe drinking water supply.

Appendix 1 Emergency Notification Protocol

May 216 ENGINEERING OPERATIONS 5.4.3 DISINFECTION PROCEDURES - WATERMAIN REPAIRS OR TIE-INS INTENT: Watermains are to be disinfected whenever the system has been exposed to atmosphere. The following procedures are based on AWWA Standards C651-92. 5.4.3.1 REPAIRS OR TIE-INS WITH NO GROUNDWATER ENTRY INTO WATERMAIN: These typically consist of electrolysis holes, cracked or split watermains which are repaired using robar repair clamps. Assuming that the watermain will have a positive outflow of water until the trench is excavated below the invert of the pipe, we can determine that no contaminant has entered the watermain. a) Under these circumstances the only disinfection required is to swab the area to be repaired and the repair clamp with 6% chlorine solution. (household bleach) b) No bacterial tests are required. c) After repairs have been completed, it is recommended to flush the watermain. d) If positive pressure cannot be achieved, more disinfection is required. See 5.4.3.2. 5.4.3.2 REPAIRS OR TIE-INS WITH GROUNDWATER CONTAMINATION OF THE WATERMAIN: These are cases where large blowouts have occurred, or it has been impossible to maintain continual outflow from the watermain, or impossible to pump down below watermain before shutting it off. We would then assume that ground water has entered the watermain. These cases require disinfection and bacterial testing. Results of bacterial test are required before putting watermain back in service. In these cases, a written notice shall be given to affected residents and bottled water shall be provided. a) Valves feeding each side of break should be left cracked open. b) Once repairs begin, groundwater must be kept below the main. (Pumps, vactor etc.) c) Ground water and debris in main should be flushed out if possible. d) All repair pieces must be swabbed with 6% chlorine solution before installation. e) Bacterial samples shall be taken from the repaired area as well as one up and one downstream from the isolated break area. In addition, one test shall be taken from a nearby hose bib to compare as the source. f) These bacterial samples are to be taken to a certified bacterial lab for total and fecal coliform analysis. g) These tests are taken as a precautionary measure. However, if samples come back positive (coliform present) then further disinfection and testing is required. See 5.4.3.3. 5.4.3.3 E.COLI DETECTED: If E.coli is detected, that section of main must be shutdown until disinfection and proper retesting is completed. Any case where a test comes back positive, the waterworks engineer, a F:\Eng\Water Quality Report\215 Water Quality Report\Appendix 1-Emergency Notification Protocol\Emergency Notification Protocol.docx

member from Environmental Services and Fraser Health must be notified. May 216 Chlorination of the watermain may require complete isolation of the main. Disinfection of the watermain requires a minimum concentration of 2 ppm for a retention time of 2 hours. At the end of this time the chlorine residual must be a minimum of 1 ppm. If this is not met re-chlorination must take place. After chlorination, the watermain must be flushed until chlorine residual is less than 1 ppm. Individual services should also be flushed to remove chlorine that may have entered these connections. 5.4.3.4 WASTEWATER OR OTHER SERIOUS CONTAMINATION: In any case where a watermain break is accompanied by a broken sanitary sewer, the procedures for 5.4.3.3 should be followed. The watermain must not be put back into service until 3 consecutive successful samples, 24 hours apart, have been obtained for E.coli.

Appendix 15 Health Information

What can I do if there is arsenic in my drinking water? Water with arsenic is a problem only if you are using it for drinking, preparing food or watering food plants. Exposure through breathing and skin contact is not harmful. For example, there are no known health effects from hand washing, bathing, or washing clothing in water with arsenic. If an initial test detects arsenic, even at levels below the guideline, it is important to have a second test done to confirm the results. If arsenic is present, then you can either use another source for drinking water or treat the current source. Chlorination and mechanical filters do not remove arsenic from water. Boiling water may increase the concentration of arsenic and make the problem worse. There are several treatment options for removing arsenic including reverse osmosis filters and distillation. There is no regulatory control over treatment devices for private homes, so you have to be careful to buy one that works for removing arsenic. Look for a treatment device that has been certified by an organization accredited by the Standards Council of Canada (SCC) and meets one of the following standards: NSF/ANSI Standard 62 on drinking water distillation systems; or Standard 58 on reverse osmosis drinking water treatment systems; or Standards 53 on drinking water treatment units with specific designation for arsenic. Be sure to operate and maintain your treatment device as per the manufacturer s instructions and test your raw and treated water regularly for arsenic to make sure that the device is indeed working properly. For more information pertaining to drinking water and other services, visit the Fraser Health website below or contact the Drinking Water Program staff at 1-64-87-79. www.fraserhealth.ca/your_environment Health Protection is responsible for regulating and monitoring many public facilities and those aspects of the environment that have a direct impact on public health. Our mission is ensuring healthy people and healthy environments. Revised: December 213 Arsenic in Well Water Information for Private Well Owners Health Protection Ensuring Healthy People and Healthy Environments

Drinking water that contains arsenic can have serious short-term and long-term health effects. As you can see on the map, some groundwater in the Fraser Valley is known to contain arsenic concentrations exceeding Health Canada s Maximum Acceptable Concentration (MAC) of.1 (1 ug/l or 1 parts per billion). This pamphlet provides information about arsenic, including how to test your well water for arsenic and what to do if arsenic is found in your well water. Pre-Treatment Arsenic Levels <.3 - negligible risk.3-1. - meets Health Canada s MAC 1. - 1. - exceeds Health Canada s MAC 1. or greater - potential for toxicity without treatment For a detailed and larger area view of the above Arsenic Map visit the Fraser Health website at: www.fraserhealth.ca/your_environment/ drinking_water/resources/private-well-owners/. How does arsenic get into drinking water? Arsenic can get into drinking water from natural deposits or runoff from agriculture, mining or industrial processes. In British Columbia, natural minerals are the most common sources of arsenic in drinking water. The amount of arsenic found in groundwater wells is usually higher than that found in surface water supplies such as lakes, streams and rivers. What are the health effects of arsenic exposure? Arsenic in water is a concern only if the water is being used for drinking or preparing food. Exposure through breathing and skin contact is not harmful. For example, there are no known health effects from hand washing, bathing or washing clothing in water with arsenic. However, if you use your water for drinking or preparing food, water that contains arsenic can have serious short-term and long-term health effects, depending on how much arsenic is in your water and for how long you drink it. Short to medium-term (days to weeks) exposure to very high levels of arsenic (over 2 parts per billion) in drinking water can lead to arsenic poisoning. For an added margin of safety, do not drink water containing 1 parts per billion arsenic or greater. Symptoms of exposure to high levels of arsenic include stomach pain, vomiting, diarrhea, and impaired nerve function, which may result in pins and needles sensation in hands and feet. As children tend to drink more water per unit of body weight than adults, they may have more exposure to arsenic in drinking water and may be at greater risk of illness when higher levels of arsenic are present. Long-term (years to decades) exposure to even relatively low amounts of arsenic in drinking water can increase your risk of developing certain cancers, including skin, lung, kidney, and bladder cancer. The risk of cancer is the reason for developing the Canadian guideline for arsenic in drinking water. Long term arsenic exposure can also cause skin changes, including darkening, and wart or corn-like growths mostly found on the palms of the hands and soles of the feet. Health Canada set a Maximum Acceptable Concentration (MAC) of.1 (1 ug/l or 1 parts per billion) for arsenic in drinking water. This level was set based on the ability to treat water practicably to this level. This amount is still linked with a health risk higher than the level considered to be a very minor risk. For this reason people should consider taking precautions with their drinking water even if the arsenic levels are slightly below the guideline. For more information on arsenic in drinking water and the Guidelines for Canadian Drinking Water Quality visit the Health Canada website at www.hc-sc.gc.ca. How can I find out if there is arsenic in my drinking water? Any well may contain arsenic or other contaminants. As the well owner, it is your responsibility to test your well water for arsenic and other indicators of water quality. Arsenic in drinking water has no odour or taste. It is detected by a chemical test that is done only by specialized laboratories. For a list of Laboratories Analytical check the yellow pages in the telephone book or contact an Environmental Health Officer in the Drinking Water Program at 1-64-87-79. For more information on water testing go to www. healthlinkbc.ca/healthfiles/hfile5b.stm. See file #5b Should I Get My Well Water Tested? www.fraserhealth.ca

Responsibilities of a Water System Owner/Operator BULLETIN From Environmental Health Services Under the Drinking Water Protection Act and Regulation owners and operators of a drinking water system are responsible by law to ensure that the water is safe for domestic use. Domestic use is defined as water used for human consumption, food preparation or sanitation (i.e., water used for drinking, cooking, cleaning, etc.). The following table is a summary of the water system owner and operator responsibilities. 1. Supply Safe Drinking Water (Act s.6, Reg s.5) All water supplied to customers/users must be free from harmful microorganisms (bacteria, viruses or parasites). Health related chemicals found in the drinking water must not exceed certain levels. Drinking water taken from surface sources (lake, creek or spring) or ground water sources (shallow well) at risk of containing harmful microorganisms must be treated (i.e. Chlorine, Ultra Violet light). 2. Construction Permit (Act s.7, Reg s.6) 3. Operating Permit (Act s.8, Reg s.7) 4. Operator Training (Act s.9, Reg s.12, 4.2) Construction permits are required to construct a new water system or to alter or extend an existing water system. To operate a water system requires a valid Operating Permit issued by Fraser Health. Terms and Conditions may be applied to the permit where necessary. A Certifi ed Operator is required for all water systems serving a population of 5 or more persons. A small water system is not required to have a certifi ed operator unless otherwise required by the Drinking Water Offi cer/inspector as a condition on your operating permit. Health Protection Ensuring Healthy People and Healthy Environments Printshop #256396 August 21

Responsibilities of a Water System Owner/Operator 5. Water Sample Collection & Testing (Act s.11, Reg s. 2,8,9) 6. Emergency Response Plan (Act s.1, Reg s.13) 7. Immediate Reporting (Act s.12, Reg s.9) 8. Notify Drinking Water Officer of Threat (Act s.13) 9. Notify Water Users of Threats to Drinking Water (Act s.14) 1. Publication of Information (Act s.15, Reg s.11) Recommendation: Operation & Maintenance Recordkeeping Owners/operators are required to collect and submit water samples to an approved laboratory. The laboratory tests for the presence of total coliform and E.coli bacteria. Owners/operators are expected to have the drinking water tested for specifi c chemicals every 3 to 5 years. Owners/operators must have a written plan detailing what they will do in the event of an emergency (e.g. if the drinking water supply becomes contaminated with E.coli bacteria issue a boil water advisory to all users). If an owner/operator receives a report from a laboratory regarding an E.coli positive water test result, he/she must immediately notify Fraser Health (Drinking Water Offi cer/inspector). As soon as an owner/operator becomes aware of a possible threat to their water system (e.g. chemical is spilled into their water supply or someone has tampered with their system) he/she must immediately notify Fraser Health (Drinking Water Offi cer/inspector). If an owner/operator becomes aware of a possible health threat and is unable to immediately notify the Drinking Water Offi cer/inspector, he/she must immediately notify the users of the drinking water supply of the threat. For example: Owner/operator receives a report from a laboratory regarding an E.coli positive water test result or Owner/operator considers that there may be a health threat to the drinking water system. Owners/operators are required to make various types of information public. This includes information regarding their emergency response plans and water quality monitoring test results. Owners/operators should keep a record of routine maintenance and repairs, water test results, operational issues, etc. Unofficial versions of the act and regulation can be downloaded from: www.hls.gov.bc.ca/protect/dwact.html For any questions or concerns contact your Drinking Water Officer/Inspector at 64-87-79.

Number 56 August 29 Drinking Water and Those with Weakened Immune Systems Some people with very weak immune systems may be at higher risk of water-borne infections. This file provides information about how to help prevent water-borne infections. People who have significantly weakened immune systems and who are at higher risk of certain water-borne diseases include: People with HIV infection who have a CD4+ count of < 1 cells/mm 3. People with hematological malignancies (lymphoma or leukemia) who are being actively treated or have been in remission and off treatment for less than 1 year. Hematopoietic stem cell transplant recipients. People born with diseases that severely affect their immune systems. Some people with weakened immune systems, such as those with certain types of cancers or taking certain medications, may not be at higher risk of severe water-borne diseases. These people do not need to take extra precautions with their drinking water. Ask your doctor or specialist how weak your immune system is, and whether you need to take extra precautions. Diseases from drinking water Drinking water can contain different organisms, including bacteria, viruses and parasites, which can cause disease. These organisms can exist in the source water such as lake water and survive through treatment, or they can enter the water supply in the distribution system. Well water can be contaminated if the well is not built properly or if it draws on water from the surface of the ground, such as shallow wells or wells drilled in fractured rock. Surface water, such as rivers, lakes and streams, can also contain disease-causing organisms from animal feces. If you have a weak immune system, you should not drink water from surface sources or wells potentially contaminated by surface water (for example, dug wells), unless the water has been treated to remove or inactivate at least 99.9% of parasites (protozoa), 99.99% of viruses and 1% of harmful bacteria. Most community water systems in B.C. have effective treatment, such as disinfection or chlorination, against bacteria and viruses. However, in many cases, treatment may not provide a 99.9% reduction in infectious parasites. Furthermore, some water systems and many private supplies have no treatment at all. If the water you drink has not been disinfected, please refer to HealthLink BC File #49b How to Disinfect Drinking Water. To further treat drinking water that has been disinfected, consider the methods listed below. Options for water treatment Boiling: If your water supply is disinfected you need only bring the water to a full boil to inactivate any Cryptosporidium parasites - a major concern for immunocompromised people, as there is no medical treatment for this parasite. If the water is not yet disinfected, it s recommended you bring water to a full boil for at least one minute as the best way to kill or inactivate bacteria, viruses and parasites.

For more HealthLink BC File topics, visit www.healt hlinkbc.ca At elevations over 2, meters [6,5 feet], you should boil water for at least two minutes to disinfect it. In this situation, you should not drink or use tap water to brush your teeth, rinse your mouth, mix drinks or make ice cubes without boiling it first. If you are preparing infant formula, please see HealthLink BC File #69b Formula Feeding Your Baby: Safely Preparing and Storing Formula. Please note that boiling water will get rid of viruses, bacteria and parasites but not chemicals which may be found in the water. For more information, please contact the environmental health officer or drinking water officer at your nearest public health unit. Filters: If you plan to install a drinking water filter in your home, you will need a system labeled as "Absolute" 1 micron or smaller, and labeled as meeting ANSI/NSF International Standard #53 for removal of parasites. These are not suitable for removing bacteria and viruses and should not be used unless the water supply is at least disinfected first. Jug-type filters, which sit in a jug and allow water to trickle through, and some tapmounted and built-in devices are not an appropriate solution. The jug filter models are not effective in removing many diseasecausing organisms. Reverse Osmosis (RO): RO is effective against all disease-causing organisms and many chemical contaminants. Unless it has a high capacity, it will only produce small amounts of water and waste a large volume. Speak to a water treatment specialist to see if this is the best option for you. Ultraviolet (UV) Treatment: UV light will kill many disease-causing organisms, and it is effective against almost all parasites. UV will not kill some bacterial spores and some viruses, so it should not be used unless the water supply is at least disinfected. UV treatment units should meet NSF Standard #55A. Bottled water If you do not want to drink water from the tap, you may also choose to buy bottled water that has been treated adequately. Most bottled water in B.C. has had RO treatment, but not all has been treated. You should check with the water bottler to find out what treatment it has had. You can still use tap water for cooking as long as you boil it. You can use bottled water treated by reverse osmosis for drinking, brushing teeth, making ice cubes and for recipes where water is used but not boiled such as cold soups or salad dressings. For more information, including the level of treatment in your local water system, please contact your drinking water purveyor or supplier or the local environmental health officer or drinking water officer.
