This report from The Deben Climate Centre describes E.coli and phosphate pollution in the River Deben. It is the result of more than 12 months of sampling and testing results from over 25 locations, with a particular focus on the impact that Waste Water Treatment Works (WWTW) have on pollution levels. These treatment works are owned and operated by Anglian Water but governed by standards set by the Environment Agency.
