Microbiological monitoring in support of drinking water quality assurance covers a range of indicator organisms. Fapas drinking water microbiology proficiency tests are enumeration and identification tests which cover the major indicators of colony counts, total coliforms (with a separate E. coli test), enterococci, Pseudomonas and Clostridium. The performance assessments are supported by a unique statistical study undertaken by Fapas.

The colony counts are especially important for quantifying potential contamination within water and wider environments due to the large effect water has in the food chain. As such this indication can provide an insight into any potential issues that may arise from the preparation of foodstuffs and as well as direct drinking water. Being proficient in these tests can inform later stage testing, but also has extensive effects if inaccurate testing is used, increasing potential risks of contamination in drinking water.

Fapas proficiency testing measures can challenge your testing ability in much the same way as your routine analysis activities. This can therefore provide effective comparisons to your routine activities from which to ensure clear and concise improvements can be made within your testing activities. This can then inform your wider quality assurance processes, ensuring high quality testing practices to satisfy regulators.
