  • Water Quality Monitoring

    Water quality sampling and watershed monitoring make up an important part of the overall mission of the Division of Water Supply Protection . These activities are carried out by Environmental Quality Section staff at Wachusett Reservoir in West Boylston and at Quabbin Reservoir in Belchertown.

    Annual Water Quality Reports are produced for both the Wachusett Reservoir and the Quabbin Reservoir & Ware River watersheds.

    These reports detail the results of sampling performed in the tributaries and the reservoirs for bacteria, nutrients, conductivity, temperature, turbidity, algae, hydrogen ion activity and giardia/cryptosporidium. Read more .
