Understanding Enterococci in water

Enterococci are a group of bacteria used as reliable indicators of faecal contamination in water, particularly in recreational and environmental water monitoring. Their presence is often associated with sewage ingress or animal waste contamination and, unlike other bacterial indicators, they are well-suited for survival in saltwater and harsher conditions. This makes Enterococci an essential parameter for monitoring water quality in both inland and coastal environments, as well as in treated water systems where hygiene and safety are critical.

Supporting water quality assurance and environmental compliance*

Enterococci testing is recommended by regulators and public health bodies across Europe and the UK, including within the EU Bathing Water Directive, the Private Water Supplies Regulations, and other environmental monitoring frameworks. In addition to its role in safeguarding public health, routine testing can support early detection of system ingress or breakdowns in filtration and disinfection processes. Whether you are monitoring surface water, potable supplies, or treated effluents, testing for Enterococci provides a strong indicator of microbiological safety and compliance.
