The Environment Agency works to create better places for people and wildlife, and supports sustainable development. Within England, we’re responsible for regulating major industry and waste; treatment of contaminated land; water quality and resources; fisheries; inland river, estuary and harbour navigations and conservation and ecology.  We are also responsible for managing the risk of flooding from main rivers, reservoirs, estuaries and the sea.
