Water Microbiology (QWAS)

Our Quality in Water Analysis Scheme (QWAS) has been specifically developed for the microbiological analysis of waters and effluent sludge. Microorganisms occur in water naturally and the majority are relatively harmless; however, contamination of water from faecal sources can lead to large outbreaks of disease.

 

In many countries, water microbiology is the subject of legislation. Regulations specify how often water sources are sampled, how sampling is done, how analysis will be performed, for which microorganisms to test, and the acceptable limits for the target microorganisms. For laboratories responsible for the analysis of waters, participation in a relevant LGC Proficiency Testing scheme can provide confidence that results of these analyses and the equipment used to produce those results are meaningful and accurate which, in turn, helps to ensure water safety.
