Using information from many sources, we aim to understand the health of our waters and the landscape around them.

We want to make sure that any action taken to improve water quality makes a difference. It is important that we have the evidence to show this, so we know what works - and what doesn’t.

We focus on:

  • What are the main problems with water quality?
  • Where are these problems?
  • What’s causing these problems?
  • How can we fix them?

The EPA works with local authorities, government departments and other public agencies and bodies to do this. We bring together and analyse information from these and other sources to understand how what is happening in our catchments affects our waters.

Money and other resources will always be limited. This means it is important to focus on actions that will improve water quality.
