Water Quality Monitoring on the Jones River, Duxbury, MA

A map of Cape Cod Bay.

Since May 2006, NECWA has participated in a water quality monitoring program sponsored by the Provincetown Center for Coastal Studies. From May until November, NECWA staff and associates assess and collect water at Mulliken’s Landing on the Jones River, in Duxbury, MA. This monitoring effort is part of a larger program headed by Dr. Amy Costa, a scientist at the Center for Coastal Studies, to investigate and document the quality and health of Cape Cod Bay.

Two or three times each month during mid-ebb tide, NECWA personnel collect water samples and conduct a number of on-site tests from a boat ramp at Mulliken’s Landing. Water quality parameters analyzed on-site include temperature, pH, salinity, dissolved oxygen and turbidity. And a number of water samples are collected for later analysis of specific water parameters including chlorophyll a concentration and nutrients, (nitrogen and phosphorus). All collected samples are frozen for future transportA NECWA staff member entering data after collecting water samples. and analysis at the Center’s water quality laboratory in Provincetown.

Public volunteers, sampling at specific sites along the shores of Southeastern Massachusetts, play an important role in the Center’s monitoring program. Each year, these citizen scientists provide important water quality information and samples from at least 12 sites that border Cape Cod Bay. Many of these sites are located further inshore in areas not accessible by boat. This information is used by scientists at the Center for Coastal Studies to protect and when possible restore the Bay’s estuaries and marshes, barrier beaches, creeks, rivers and harbors from human and natural threats.The Jones River in Duxbury.

The Cape Cod Bay Monitoring Program is a wonderful example of a community commitment to the marine conservation of Cape Cod Bay, an ecologically rich and complex bay that became a State Ocean Sanctuary in 1970.
