The Environment Agency has a responsibility to manage and improve the quality of our water
resources. Two new research projects were commissioned to find out how some of the chemicals regularly washed into rivers and streams can affect the wildlife living there. The research has demonstrated that chemicals which mimic naturally occurring hormones can affect wild freshwater snails and that some effects may have long-term implications for population health and reproduction. This report will inform our decision-making on how best to monitor and manage these chemicals in water courses.
