For over 20 years, we have tracked water quality in marine embayments, as well as keeping a close eye on freshwater systems including ponds, streams, rivers and coves. By monitoring, we can then measure the quality of these water systems through comprehensive parameters and proven scientific methods that provide both qualitative and quantitative data. These data are shared with other science-based organizations, and provide the BCWC with a baseline to determine progress.

Measuring water quality through comprehensive, proven scientific methods provides data targeted for a strong and sustained ecological impact.

BCWC is monitoring the streamflow and nitrogen levels to determine how much nitrogen is flowing through the Marstons Mills River and into the Three Bays estuary.


BCWC has been collecting water quality data at the Marstons Mills cranberry bogs that shows it is a collection area for the groundwater from much of the surrounding residential developments and could play a vital role in reducing this same nitrogen load in our watershed.


BCWC has worked with UMass Dartmouth’s School for Marine Science and Technology (SMAST) for 15 years collecting water quality data.

BCWC is an active participant in the Cape Cod Commission’s Cape Cod Pond and Lake Stewardship (PALS) program.  BCWC monitors 31 ponds and lakes in Barnstable.


BCWC has been monitoring the Marstons Mills River Herring Run and collecting data that estimates how many herring make it to Mill and Middle Ponds.
