The Environment Agency (EA) is responsible for maintaining or improving the quality of fresh, marine, surface and underground water in England and Wales.
The Drinking Water Inspectorate (DWI) is the national body responsible for ensuring the quality of drinking water.
We deal with water quality issues in three areas:
- private water supplies - for those who extract their water from boreholes, wells and natural springs. We monitor for bacteria and chemical parameters. Find more information on our private water supplies page.
- bathing waters - including swimming pools at leisure centres, jacuzzis and hydrotherapy pools, hotels and private health clubs. We check for chemical levels and bacteria through our sampling programme
- mains water - including manufacturers of food and drink and, sometimes, the domestic supply
- providing safe drinking water
- meeting water quality standards
- public sewers
- burst water mains
If you're unsure who supplies your water, you can find out by entering your postcode on the Water UK website.
