1 FQs & Glossary Updated October 2011 Frequently sked Questions Q Why have these particular characteristics been chosen for testing? Sydney s water is tested for up to 70 different characteristics covering micro-organisms, taste, colour, odour and chemical content. Sydney Water has reported on a selection of characteristics of particular interest to the customer. These have been chosen in consultation with NSW Health. Q What are the NH&MRC guidelines? The ustralian Drinking Water Guidelines are jointly set by the National Health and Medical Research Council (NH&MRC) and the gricultural & Research Management Council of ustralia & New Zealand (RMCNZ). They are based on World Health Organisation (WHO) levels that have been adapted to suit local conditions. In 2004 the Council revised the guidelines in consultation with the general community, health bodies, water suppliers and regulators superseding the previous 1996 guidelines. The guidelines are continually reviewed and revised by the NH&MRC as new information comes to light. Q How do these results relate to the quality of the water at my front tap? We do not sample at everyone s tap but we do have representative sample sites in each water delivery system. This includes hundreds of taps across all systems. The sampling program has been designed to give a clear picture of what the water quality is like at all customers taps across the system. Q Do the results mean the water is safe to drink? The data is indicative of the quality of water from the catchment to the customer. Sydney s water is comparable to the best in the world. Sydney Water has in place a strict measurement and reporting process for water quality which is based on an agreement with the NSW Health. In the event that the water is not safe to drink or should an incident such as the Cryptosporidium contamination of 1998 occur, we will act through an agreed protocol with NSW Health and they will advise you of any health issues. Q How often do you test and where are the samples taken from? Water quality testing and monitoring takes place at various times and stages of the storage and distribution process to ensure that it is safe and that water quality standards are met. Samples are taken from customers tap's, at reservoirs, on the outlet of water filtration plants, within the water

2 filtration plants for operational purposes and in the raw water. Depending on the type of water quality characteristic, samples may be taken daily, weekly, monthly, quarterly or annually. Some water quality parameters are monitored continuously (on-line) at the Water Filtration Plants. Q Who does the testing? re the tests done by an independent body? The majority of water testing is conducted by Sydney Water laboratories. The laboratories are accredited by the National ssociation of Testing uthorities (NT) and the laboratory processes undergo frequent internal, second party and independent audits so the public can be assured that results are verified and accurate. NSW Health reviews the outcomes of these audits and engages an independent laboratory to conduct parallel analysis for Cryptosporidium and Giardia to verify Sydney Water s test results. Q What does it mean when you hear about "hard" and "soft" water? Water hardness is mostly a measure of the Calcium Carbonate (CaCO 3 ) concentration in milligrams per litre. Below 60 mg/l water is considered soft and above that level it is considered hard. For Sydney s water the average reading is around 57 mg/l so the water is considered soft. Q How can we be sure these results are accurate and can I trust these results? The water quality information released to the public has gone through a quality process, which is set up in agreement with NSW Health. Quality assurance systems are in place at all stages of the various processes of monitoring, analysis, verification and reporting. Both Internal and Independent udits are carried out regularly on all these processes to ensure the integrity and accuracy of the information being provided. Q What is Sydney Water doing to prevent another water quality crisis? Sydney Water in conjunction with the Sydney Catchment uthority (SC) have conducted significant amounts of work since the 1998 water quality incident. We have: increased monitoring of raw water storage at dams; improved controls on raw water flowing into our water filtration plants; established a standing panel of water quality experts, along with NSW Health; improved catchment management; and reviewed all processes within the Water Filtration Plants. One of the important outcomes of the water quality incident was the establishment of the SC. Its purpose is to protect and enhance the quality of water and catchment management.

3 Glossary Labelling system devised to define how water efficient appliances such as washing machines and dishwashers are. = Excellent, = Good, = cceptable. NZECC ustralian and New Zealand Environment and Conservation Council provides a forum for the development of national land use policies to protect environmental quality and for the setting of national objectives for air, land and water quality.

Biodegradable substance that can be broken down into harmless products in the environment. Biodiversity Variety and number of different species living in an ecosystem or a defined geographic area. Biofilm n accumulation in water pipes, which may harbour microorganisms. C Calcium (Ca) naturally occurring element, which can enter the water from the catchments. It may also be added to water in the treatment process to reduce the acidity levels. Catchment rea where water is collected by the natural landscape. In a catchment, all rain and run-off water eventually flows to a creek, river, lake or ocean, or into the groundwater system. Catchment (Inner / Special rea / Enclosed) The area immediately surrounding a dam or stored water supply which is closed to access to protect water quality. Catchment (Outer) reas surrounding the inner catchment where human activity is permitted but may be restricted to protect water quality. Chlordane n organochlorine pesticide used to treat termites.

5 Chlorination The application of chlorine to drinking water, waste water, or industrial waste to kill bacteria or to oxidise undesirable compounds. Chlorine (Cl) Chlorine is a disinfectant. To ensure good quality drinking water, chlorine is added to kill bacteria that may cause disease. We test for the residual chlorine that needs to be present to make sure that the water is disinfected all the way to your tap. The health guideline value for chlorine depends on the type used. Some systems use 'free' chlorine (5 mg/l) and others use monochloramines (3 mg/l) Chloramination mmonia as well as chlorine is used as a disinfectant in drinking water. The disinfection properties are longer lasting and this is beneficial in delivery systems which are over a longer distance. Chlorophyll a Is a pigment produced by plants and indicates the potential presence of algae in stored water. Coliforms (Total) Total coliform bacteria are used as a scientific indicator of the quality of drinking water and of the possible presence of disease causing micro-organisms. They are measured in colony forming units per 100 ml. There is no DWG 2004 value for coliforms due to the lack of direct health significance. Colony Forming Unit (orgs) Unit used to represent numbers of bacteria. Conservation Use, management and protection of resources so that they are not degraded, depleted or wasted and are available on a sustainable basis for present and future generations. Cryptosporidium (Crypto.) re parasitic protozoans occurring in warm-blooded animals. Some virulent strains of Cryptosporidium can infect humans. These micro-organisms occasionally occur in a dormant state (oocysts) in the untreated water supply however filtration will normally remove them from the water. Cryptosporidiosis disease of humans caused by the ingestion of virulent strains of Cryptosporidium oocysts, usually as a result of person-to-person contact.

6 Customer Supply System The network of pipes, pumps and local reservoirs that deliver water from the water filtration plants. Cyst resting spore of many algae, pathogens and protozoa.

Ferric Chloride This is an iron based chemical used as a water treatment chemical in some parts of the world. Filtration (Water) process for removing particles from water by passing it through a porous barrier, such as a screen, membrane, sand or gravel. Often used in conjunction with a flocculant to settle contaminants. Flocculant chemical which encourages heavy contaminants to gather together and settle from water more quickly in the treatment process.

8 Fluoride Small amounts of fluoride are added for dental health reasons in accordance with legislation. Typically 1 mg/l is present in Sydney s water supply. Flushing process of pipe cleaning through the increased flow of high pressure water. G Giardia re parasitic protozoans which occur in warm-blooded animals. These micro-organisms occasionally occur in a dormant state (cysts) in the untreated water supply. Disinfection and treatment processes normally inactivate or remove them from the water. Giardiasis disease of humans caused by the ingestion of Giardia cysts, usually as a result of person-to-person contact Guideline Values Values to assess water quality.

13 S Sediment Soil or other particles that settle to the bottom of lakes, rivers, and other waters. Special reas Lands mostly around drinking water storages that were originally set aside for the protection of drinking water quality. The lands are declared as Special reas under the Sydney Water ct 1994 ("The ct""). Parts of the Special reas are also National Parks, nature reserves and State Recreation reas and are jointly managed by Sydney Water and NPWS. Soluble ble to be dissolved in water. Suspended Solids Particles in water that can be removed by sedimentation or filtration Swabbing The cleaning of mains using mechanical in-pipe cleaning tools. T Thermotolerant Coliforms are a type of coliform that can grow at higher temperatures than other Total Coliforms. They are also known as Faecal Coliforms. Total Coliforms are a family of bacteria commonly found in the environment. Some members of the family come from the environment and other members from intestines of humans and other warm-blooded animals. Due to their widespread occurrence in most soil and water environments, they are no longer regarded as the most reliable indicator of human or animal contamination. E. coli is now regarded as a more important indicator organism for public health. Trihalomethanes (THMs) THM's are formed in water when chlorine reacts with small amounts of naturally occurring organic matter. THM's are measured in mg/l.

14 Treatment (Water) The filtration and disinfection process. True Colour Water should be virtually colourless however the appearance of colour can be caused by the presence of excessive dissolved minerals and humic acids. It is measured in Hazen Units (HU). Turbidity measure of the amount of suspended material (usually fine clay or silt particles) in water and thus the degree of scattering or absorption of light in the water. W Wastewater nother name for sewage. Water Filtration Plant (WFP) treatment plant that improves water quality by removing impurities through filtration. Water Supply System The network of pipes, pumps and local reservoirs that deliver water from the water filtration plants. Water Reuse The use of water more than once, following treatment of wastewater to an appropriate quality standard and delivery to the point of use. Z Zinc (Zn) Zinc is a metallic element which can enter the water from the catchments and is also used as a coating to prevent corrosion of iron and steel products which may be responsible for taste problems with water.
