The health of the Agawam River estuary has climbed to fair since 2005, when Wareham upgraded its Water Pollution Control Facility. Although this sewer plant reduces far more nitrogen than any other in the region, it still discharges to the Agawam River. The discharge pipe must be moved to a less sensitive location away from the Agawam River for the estuary’s health to keep improving.
