Boston Harbor Sediment Quality Responds to Cleanup

Today, unlike a generation ago, the discharge of sewage into Boston Harbor, plays a small role in the loading of contaminants to Boston Harbor. The investment in state-of-the-art facilities, which effectively remove contaminants from the waste stream, has enabled Boston Harbor to recover from the past contaminant loading. Evidence of the improvements are found in contaminant load reductions, downward trends in sewage tracers and contaminant concentrations in surface sediments, and improvements in sediment quality
