Cape Cod Herring Run


Our small but intrepid team of engineers, scientists, seasonal help, and interns implement and test innovative technologies including alternative septic systems, permeable reactive barriers, and nature-based treatment systems. We support municipal treatment projects. By utilizing solution-based initiatives in our mitigation program, we help combat excess nitrogen by using innovative technologies to clean the water.

Solutions-both traditional and new-to cleaning impaired waters in ponds, rivers, and embayments exist through the diverse Massachusetts 208 Plan, named for Section 208 of the federal Clean Water Act. These technologies include aquaculture, which uses oysters to filter and purify water naturally, and Permeable Reactive Barriers (PRBs), which are underground walls that filter impurities from groundwater to combat nitrogen pollution. These are just a few of the innovative methods in which Barnstable Clean Water Coalition is engaged.

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.

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.
