Checklist 6: Water Quality Monitoring
1. Sampling Program
☐ Sampling plan established
Sampling locations, frequencies, and responsibilities should be clearly defined and documented.
2. Sampling Locations
☐ Representative sampling points selected
Samples should be collected from sources, treatment facilities, reservoirs, distribution systems, and consumer taps.
3. Microbiological Testing
☐ Microbiological analyses performed
Testing for indicator organisms helps verify microbiological safety and detect contamination events.
4. Physical Parameters
☐ Physical water quality monitored
Parameters such as turbidity, temperature, and conductivity should be regularly measured.
5. Chemical Parameters
☐ Chemical analyses performed
Relevant chemical parameters should be monitored according to source characteristics and risk assessments.
6. Laboratory Procedures
☐ Approved laboratory available
Analyses should be performed using validated methods and appropriate quality assurance procedures.
7. Trend Evaluation
☐ Results reviewed and evaluated
Long-term trends and unusual changes should be investigated and documented.
8. Corrective Actions
☐ Response procedures established
Clear actions should be defined for situations where monitoring results indicate contamination or system failures.
