Microbiological analysis

The use of indicator bacteria such as Escherichia coli (E coli) and coliforms as a means of assessing water quality and public health has long been established.

More subtle changes can be monitored by interpretation of total colony counts and together with the indicator bacteria provides a basic and reliable microbiological monitoring. This standard suite of parameters can be enhanced to provide a more comprehensive assessment.    

Bacteria can easily populate any plumbing service by forming biofilms as a result of low turn-over inside long runs of pipe work, dead legs or cold water storage tanks. Cold water storage systems that are not insulated, have inadequate insulation, have large amounts of deposits or sediment inside the cistern can also be a potential breeding ground for bacteria. We can assess any areas of risk, perform sampling and analysis and identify if bacteria are present.
