Eurofins Water Hygiene Testing UK Ltd provides UKAS No. 9658 and 1369 accredited testing for Escherichia coli (E. coli) to support water treatment and management professionals across all sectors. Testing for E. coli plays a vital role in protecting public health and maintaining compliance with UK water quality regulations.
Understanding E. coli in water
Escherichia coli (E. coli) is a trusted indicator of faecal contamination in water supplies, whether potable, process, surface, or wastewater. As a member of the coliform bacteria group, its detection, even when specific pathogenic strains are absent, signals potential sewage or animal waste ingress. The presence of E. coli highlights risks to microbiological integrity and potential health implications, such as gastrointestinal illness.
Why E. coli testing matters*
Monitoring for E. coli supports compliance with the Water Supply (Water Quality) Regulations 2016, Private Water Supplies Regulations 2016, and environmental legislation. Routine testing allows early detection of contamination and helps verify disinfection efficiency in treatment systems. A positive E. coli result prompts further investigation for other indicator organisms or pathogens.
Our UKAS-accredited laboratories follow validated methods aligned with regulatory alignment, with methods developed to reflect current UK and EU standards and industry best practice. Confirmed counts are typically available within 48 hours, ensuring rapid response when contamination is suspected.
