Every water body in England fails to meet chemical safety standards

In England, a recent assessment by the Environment Agency revealed that all surface water bodies are polluted with toxic chemicals, with only 14.3% achieving good ecological status. This evaluation, part of a six-yearly review, highlighted the presence of harmful substances like mercury and Pfas. The agency has set a target for all water bodies to reach good chemical and ecological status by December 2027, but projections indicate that this may not be achieved until 2063 due to the persistence of these pollutants.

Topic overview

In brief

  • Every surface water body in England has been found to be polluted with toxic chemicals.
  • Only 14.3% of surface waters achieved good ecological status, a decline from previous assessments.
  • Urgent action is needed to address the pollution crisis affecting England's waterways.

Summary

In England, a recent assessment by the Environment Agency revealed alarming levels of pollution in the country's water bodies. The evaluation, which occurs every six years, found that every river, lake, and estuary was contaminated with toxic chemicals, including mercury and Pfas, which are known for their persistence in the environment. The report indicated that only 14.3% of surface waters achieved good ecological status, a decline from 16.3% in 2019. This assessment highlights the ongoing environmental crisis affecting England's waterways, driven largely by agricultural runoff and pollution from water companies.

The Environment Agency's findings underscore the urgent need for action to address the sources of pollution. The presence of harmful substances like mercury, which is a potent neurotoxin, poses significant risks to both human health and the ecosystem. The agency has set a target for all water bodies to reach good chemical and ecological status by December 2027, but current projections suggest that this may not be achievable until 2063 due to the persistence of these pollutants.
