How Healthy is Your Water?

The inner Wareham River is in fair health. Conditions improved in the mid-2000s when Wareham upgraded its Water Pollution Control Facility. This wastewater plant now discharges far less nitrogen than any other in the region. But the river’s shoreline is densely developed, which leads to nitrogen pollution from septic systems, lawns, and roads. Cranberry bogs north of the river in Wareham, Carver, and Plymouth also play a role in its health.
