Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government how many river habitats in England have good ecological status; how many are polluted by chemical waste, including raw sewage and agricultural waste; and what steps they are taking to ensure the existing regulatory framework for managing the water environment in the UK is more effectively applied.

The last Water Framework Directive (WFD) full water body classification results in 2019 showed 16% of all surface water bodies (14% for river water bodies), in England achieved good ecological status (GES) (or good ecological potential for artificial and heavily modified water bodies), and 64% of surface water bodies achieved moderate ecological status (or potential).

The next full results will be published by the Environment Agency (EA) in 2025. The headline reporting for WFD creates a simplified picture and is just one way of understanding the water environment. For example, the last classification results for England showed the 79% of elements the EA test for GES were classed at Good.

Most water bodies failing to reach GES are subject to multiple pressures. The top three pressures are physical modification of water bodies, diffuse agricultural pollution and waste water management. More detailed information on water body reasons for not achieving good are publicly available on the EA’s Catchment Data Explorer.

The EA has developed a Prioritisation and Early Warning System (PEWS) for chemicals of emerging concern to assess their presence and quantities in our rivers. This allows the Agency to prioritise suitable management. Additionally, EA has developed a list of priority chemicals of concern which are regularly monitored alongside appropriate measures to protect aquatic wildlife and human health.

The government is committed to achieving the goals of the Environment Improvement Plan to bring 75% of our water to as close to its natural state as soon as practicable. Our Plan for Water, published last year will go further and faster towards that goal and deliver a safe, reliable, resilient supply of clean and plentiful water underpinned by increased investment in infrastructure, increased regulation and stronger enforcement.
