This project examined whether statistical relationships exist between micro-organisms routinely measured to assess bathing water quality, both within individual sites and between different sites. Recommendations were made for the design of future bathing waters quality studies to UK Water Industry Research (UKWIR)
Sampling data was examined by WRc from 22 beaches and designated bathing waters together with the UK Environment Agency (EA) database of routine monitoring data. The sampling and analytical methods used were examined to establish whether there were any relationships between salmonella and enterovirus concentrations and bacterial indicator organisms. A key recommendation was to improve sampling procedures to ensure the production of genuinely paired samples.
