The Environment Agency use standards and targets to help us protect and improve water quality.
By calculating the potential impacts of industry and agriculture on the environment they are able to set standards and targets. For example, to work out the conditions the Environment Agency must impose on discharges to protect water quality.
The standards also help the Environment Agency to check national progress in protecting water quality and work out where action is needed.
