Chichester Harbour Conservancy, in conjunction with Chichester District Council monitor the quality of the water within the Chichester Harbour. Samples from 12 locations in the harbour are collected and tested twice a month during the summer months and monthly throughout the winter.
Although there are no regulatory standards for this area of water, the EU Bathing Water Standards are used as a guide. Chichester Harbour is not a designated bathing water site, however the test results can be viewed as an indicator of potential pollution levels at the time of testing.
Historical results are available on the Chichester District Council website.
