Flow cytometry for assessing the microbiology of drinking water - from source to tap

15th May 2018

Understanding the microbiological quality of drinking water supplies is essential to the protection of public health. Many viral, bacterial and protozoan pathogens are waterborne. Water treatment processes are designed to eliminate the risk of exposure, but it is essential to carry out regular testing of water at all points from source to tap to ensure the effectiveness of treatment. Until recently, laboratories testing for bacteria in drinking water have relied on relatively slow and labour-intensive culture based methods, an inherent weakness of which is that only a small proportion of bacterial species are amenable to culture using artificial media. Flow cytometry, with appropriate staining techniques, can provide fast information on total and intact bacterial cell counts, giving an early picture of the microbiological health of a water distribution system.
