Swimming water quality monitoring is carried out at popular recreational river, lake and coastal bathing sites throughout Canterbury during summer, which allows us to assess baseline conditions, trends and public health risks.
Water samples are collected weekly from around 100 sites from mid-November to the beginning of March. Each bathing site is given an overall swimming water quality grade based on the testing of water samples collected by our staff and an assessment of the site’s susceptibility to faecal contamination.
Individual faecal indicator bacteria results are updated on our map when they are received from Hill Laboratory Services (external link) , generally within 24 to 48 hours of sampling.
