# Faeacal Indicator (microbial)

## Faeacal Indicator (microbial)

Used to sensitively indicate microbial faecal pollution from humans and/or animals in water. Information on the specific nature of the applied faecal indicator, such as sensitivity, specificity, persistence, or resistance, has to be given in order to appropriately characterise the expected indicator capacity. It is important to distinguish between indicators for total faecal pollution, including human and animals, from host-associated faecal indicators (also known as source tracking indicators or markers).
