In conjunction with Water Rangers, Surrey University, and Zero Guildford, the Trust is supporting a public 'community lab' facility which allows us to test for coliform and e.coli in the waters. An extension to the monthly testing programme, this allows us to understand the specific harmful bacteria load in the river.

For more information about the lab and how you can get involved or get a test done, visit our Community Water Lab page. with the Water Rangers.

E. coli for recreation in England is recommended to be < 1,000 CFU/100mL.
