Official classification does not guarantee clean water for swimming.
According to the Environment Agency, 97.1% of bathing waters in England have passed water quality standards following testing at over 400 designated sites carried out by the Environment Agency (EA).

These New statistics show the number of designated bathing waters meeting the highest quality standard is the most since 2015!
New locations have been given official classification after being added to the list of bathing waters in 2022.
However, the designation "does not guarantee clean water for swimming. Bringing rivers up to bathing water standards will be a challenge and places greater responsibility on farmers, water companies and communities* to remove pollution that is harmful to swimmers."
*and communities: This is where we can help householders address their surface water drainage to protect our waters from pollution. Go to our 'website search' and search 'surface water pollution' - you'll be surprised how much we can all do to help this situation.
