If you are responsible for drinking water in a commercial premises, it is important to know that the supply is safe.
Water samples should be tested to confirm that drinking water is free from bacteria that may cause illness. Potability testing assesses the number of culturable bacteria present in the sample, known as the Total Viable Count (TVC), with analysis carried out at both 22°C and 37°C.
This test, also referred to as the Aerobic Colony Count (ACC), provides an indication of the bacterial population within the water supply. While there are no fixed limits for TVC guideline values, regular monitoring can highlight significant changes in water quality. E. coli should not be detected.
