  2. DWAF Legislation National Water Act 2) Water Services Act

  3. “Summarized Mission” • Safe Water for All for Ever • Resource Protection • Discharge Treatment • Treatment of abstracted Water

  4. Branch: Policy and Regulation Chief Directorate: Water Resource Information Management (WRIM) 4- Directorates: Hydrological Services Information Programmes Surveying and Maping (GIS) Resource Quality Services

  5. Resource Quality Services • Resource Quality Monitoring • Analytical Services • Resource Quality Information • Administration and Support Services

  6. 6 Monitoring Programmes run by RQS (With various R&D, Emerging New Monitoring Prog) • National Chemical Monitoring Programme • National Microbial Monitoring Programme • National Eutrophication Monitoring Programme • River Health Programme • National Radioactivity Monitoring Programme • National Toxicity Monitoring Programme

  7. National Chemical Monitoring Programme • Sample collection and registration • Sample analysis (macro, trace metals, nutrients, pH, conductivity) • ISO 17025 accreditation

  8. National Toxicity Monitoring Programme • 12 Persistent Organic Pesticides (POP’s) • e.g. DDT (malaria control) dieldrin, HCB,etc. Pesticides used in Agriculture: -e.g. Atrazine, Simazine, carbamates etc. + Biological tests: 1) Zebra fish embrio toxicity 2) Water Flea (Daphnia pulex) toxicity Pesiticides in sediments ( needs analysis)

  9. National Microbial Monitoring Programme • Colilert (E.coli) Bimonthly reports at strategic sampling sites. • Faecal coliforms • Faecal Stretococci. • Cholera (Medical Research Institute) - type O1 Endemic in hotter parts of South Africa

  10. National Eutrophication Monitoring Programme • Orthophosphate and total phosphorus • Kjeldhal Nitrogen and NO3. • COD • pH • Ammonia • Chlorophyll-a • Algal identification and enumeration

  11. National Eutrophication Monitoring • Status and trends of algal blooms, PO4 and total P in impoundments. • Problem of toxic blooms ( eg Microcystin from cyano-bacteria and Cylindrospermopsin in Orange River) • Phosphate removal technology (UP-pilot testing).

  12. National Radioactivity Monitoring • Screening for Gross alpha, Gross beta and chemical uranium • Further testing depending on alpha/beta ratio • Association of uranium with gold mining wastes.

  13. National Toxicity Monitoring • Toxicants and toxicity tests • Stockholmn convetion (DEAT/DWAF) • EDC (WRC/DWAF) • In Pilot implementation phase • CG-MS analysis for 10 of 12 POP’s plus commonly used pesticides in Agriculture (DEAT and DA).

  14. River Health Programme • Habitat, riparian Vegetation, wetlands, SASS index (South African Scoring System for aquatic invertebrates, indicating state of river health), Fish index, etc. • Data from NCMP on chemical toxicants • Data from NTMP for organic pesticides • River classification system (A to D).

  15. Adopt a River Programme

  16. WMS • Water Quality Data Management System • Link to Google Earth • Role of GIS mapping section (IP)

  17. End • Enjoy visit to labs and IP section.
