Welcome to Barnstable Clean Water Coalition

BCWC OFFICE IS OPEN WITH LIMITED STAFF.
If you have any questions call us at 508-420-0780 or e-mail us at info@bcleanwater.org.

At Barnstable Clean Water Coalition (BCWC) our mission is simple: to restore and preserve clean water throughout Barnstable.

With science as our foundation, BCWC utilizes four core components to accomplish our mission: educate, monitor, mitigate and advocate.

Excess nitrogen leaching from septic systems causes 80% of the nutrient pollution in our estuaries. Lawn fertilizer and storm water make up most of the balance. Our freshwater ponds are under attack from phosphates and contaminants of emerging concern; again, septic systems are the main culprit. These same sources threaten our precious sole source aquifer.

Cape Cod’s “Blue Economy” requires clear, clean water to power virtually all our recreational resources. Why else come here?

Clean drinking water is a necessity, yet this resource is threatened every day.

We must act now to restore our imperiled waters before we lose them forever.

Summer Patrols

IMG_1358

BCWC’s Seasonal Staff have an active presence on Dead Neck Sampson's Island and waters throughout the Three Bays. The staff patrols Dead Neck Island to ensure visitors adhere to rules that protect endangered nesting shorebirds, and the island’s fragile dune habitat and educate boaters about clean boating practices.

BHS Pond Monitoring

During the academic year BCWC has hosted student interns from Barnstable High School. They conduct weekly sampling at Long Pond, Bearse Pond, and Wequaquet Lake.

Streamflow

Meg Samping

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.

Cranberry Bog

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.

SMAST Estuary Sampling

P1130810a

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

Pond and Lake Stewardship

SWeq 2

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.

Herring Run

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.

Invasives Monitoring

Sheath Tunicate 1

BCWC has been an active member of the Massachusetts Office of Coastal Zone Management’s (CZM) Marine Invader Monitoring and Information Collaborative (MIMIC). The data collected through MIMIC provides an early warning system for invasive species, helps identify new invasive species in the region before they spread, and improves our understanding of the ecology and behavior of established invaders. BCWC monitors seven different sites throughout the town of Barnstable.

Hyannis Oyster Upweller

Signage 1

In partnership with the Massachusetts Oyster Project (MOP) and the Town of Barnstable, BCWC built and installed an oyster upweller tank at Gateway Marina on Hyannis Harbor during the summer of 2018. The goal of this partnership was two-fold: to raise oysters from seed-size (2mm) to juvenile-size (25mm) in the upweller using water pumped from the harbor and to demonstrate that oysters improve water quality and clarity by filtering out nutrients and sediment.

Dredging of DNSI

IMG_7357

Dead Neck Sampson’s Island (DNSI) is a barrier island south of Grand Island in Osterville that is co-owned and managed by BCWC and Mass Audubon. Years of erosion and longshore drift has resulted in sand from the eastern tip (Dead Neck) moving and collecting down at the western end (Sampson’s) of DNSI.

Aquaculture and Oysters

Property Value Study

Cape Cod Harbor

The Cape Cod Commission has been a key partner in our mission to conserve the Three Bays watershed. In March 2015, the Commission released a report about property values that could be compromised by poor water quality.
