Water Quality Monitoring Program

This program monitors the health of our watersheds for state and federal reporting.

The Water Quality Monitoring Program, administered by MassDEP’s Watershed Planning Program, is responsible for evaluating the health of Massachusetts’ surface waters in accordance with the federal Clean Water Act. Program staff and citizen volunteers sample and analyze surface waters throughout the state and these data are used to prepare detailed reports on water quality. These reports assist in the preparation of Total Maximum Daily Loads, which restore the quality of the waters for their various uses (including swimming, fishing, and recreation).

Monitoring Programs

Based on long-term strategic planning (see the "Water Quality Monitoring Strategy 2016-2025" provided below), these programs provide the data for MassDEP's water-quality reporting.
