1 MINISTRY OF ENVIRONMENT AND WATER BULGARIAN EXECUTIVE ENVIRONMENT AGENCY - Partner PP12 in the Project Danube WATER integrated management WATER MIS ETC 166 Sampling and testing activities of the General Directorate "Laboratory and analytical activities Phone: Fax: [email protected] ;

2 Ruse Regional Laboratory and Montana Regional Laboratory took part in the water sampling and testing. The laboratories are structured as offices to testing laboratories in General Directorate "Laboratory and analytical activities" of the Executive Environmental Agency EEA. The laboratories were accredited in accordance with BS EN ISO from the Since 2011 the laboratories have been accredited as an offices of General Directorate "Laboratory and analytical activities" with certificate 135/ЛИ/ The laboratories carry out sampling and testing components and environmental factors water, air, soil and noise.

3 Quality Management System Testing Laboratories General Directorate "Laboratory and analytical activities" of the Executive Environmental Agency EEA operates under a single accreditation as a laboratory with 15 offices (laboratories) Central laboratory and 14 regional laboratories in accordance with BS EN ISO / IEC 17025: 2006 "General requirements for the competence of testing and calibration laboratories" since 2011 The scope of accreditation of the laboratory includes testing of water, air, noise, soil, sediment, waste products, plants, and GMOs.

4 Structure General Directorate "Laboratory and analytical activities" consists of 14 regional offices and a Central laboratory Head quarter with 8 departments. The total number of employs is 268. All of them are highly skilled engineers, physicists, chemists, biologists, technicians and other staff.

7 Quality Control Department prepares comprehend documentation regarding the procedures for accreditation of laboratories and new accreditation in accordance with the requirements of BDS EN ISO/IEC 17025: 2006; DG LAA has a system of internal laboratory control of all tested samples in comply with the requirements of good laboratory practice, as well as the instructions of the manufacturers of equipment and diagnostics; provides methodical assistance and control the quality of analyzes in regional laboratories; organizes regular courses and seminars for experts from the Directorate General with the aim of improving the qualification of staff; participates in interlaboratory comparison tests of national, European and international level: Qualco Danube, Aquacheck, Equate, Aguacom, BAM, AMOS, ILS-RIZA to ensure and control the quality of the analysis; Ensures authenticity and control of the quality data obtained by measurements on individual components of the environment.

8 Water Quality Laboratory The main activities are related to testing and ensuring data for quality of surface water, ground water, waste water, mineral water intended for drinking water, according to the monitoring programs. This activity is consistent with the requirements of the Water Framework Directive 2000/60/EEC establishing a framework of EU policy in the field of water

11 Bio Monitoring Laboratory Sampling and making hydro-biological analyzes for determination of the ecological status of water in biological quality elements (BEC) - macroinvertebrates, macrophytes, phytobenthos and chlorophyll "a" (the main characteristic of a biological element of quality phytoplankton). Microbiological analyzes for the characterization of sewage sludge for recovery in agriculture, plants and biologically treated waste. Assessment and determination of Escherichia coli, Salmonella and Clostridium perfringens.

12

13 Bio Monitoring Laboratory Sampling, detection, qualitative and quantitative determination of genetically modified DNA in plants. Control of genetically modified organisms (GMOs) into the environment and controlled conditions (according to Bulgarian GMO low and Directive EC/2001/18).

14 Radiation Measurements Laboratory The main task is to control the content of radionuclides in environmental components

15 Sampling and radiometric measurements in real conditions I.1. Environmental Sampling (soil, water, sediment, air, food and plant products, stone materials) for the subsequent radiological laboratory analysis. I.2. Measurement of gamma radiation dose in air (gamma background) with a portable gama dosimeter. I.3. Measurement of surface alpha and beta contamination - portable gama radiometer. I.4. Measurement of the concentration of radon in indoor air and outdoor.

21 RL Ruse participated in Project "WATER MIS 161" in 2013 with sampling and testing of water samples from the river Danube - left bank, middle and right bank at Ruse, Tutrakan and Silistra town. Samples were tested for 34 characteristics. Samples were taken from 19 to at following points: Ruse right bank Ruse middle Ruse left bank Tutrakan right bank Tutrakan middle Tutrakan left bank Silistra right bank Silistra middle Silistra left bank

22 Sampling was done with a hydrographic ship "Vit" APPD- of Ruse. On 19/09/2013 River at the town Ruse, 20/09/ River at the town Turtukan and 20/09/2013, River at the town Silistra, as samples were taken from the Bulgarian coast of the river environment, middle of the river and the Romanian coast, perpendicular to the current. Geographical coordinates were taken. Sampling was conducted by expert RL Ruse with job obligations of water sampling. Dates and times of sampling, that were pre-arranged with Romanian side of the project, were met. Measured characteristics at the sampling points are: active reaction ph, dissolved oxygen, dissolved oxygen saturation, temperature, conductivity, turbidity. Issued are relevant protocols for sampling of water. Ship "Vit" did provide the necessary conditions for the sample preparation of samples of water taken (filtration, conservation, appropriate storage conditions). Samples were delivered in RL Rousse on 21/9/2013. The samples were tested for 28 characteristics in the laboratory. These indicators were specified in advance by the organizers of the parallel sampling. Test results are reflected in the 12 test reports. Information about the results, methods and principles of testing, used basic technical resources and limits of determination are shown in Table 1. The test results has shown identical values at the sampling points of the river.

35 RESUME OF THE MEASURMENTS The results of the measured indicators of the samples in 2013 and 2015 show insignificant difference. The are no significant differences between the values in Silistra city and Novo Selo village. The results of the organic compounds and heavy metals are about the limits of quantification determination. The two laboratories have used same methods and equipment. That is a good base for a comparison. General, the results show good environmental status of Donau river.
