The Massachusetts Office of Environmental Affairs has several programs connected to the Clean Water Act (1967) one of which is the Massachusetts Estuaries Project which is being conducted jointly by the Massachusetts Department of Environmental Protection (DEP) and the School for Marine Science and Technology (SMAST) at the University of Massachusetts Dartmouth. In their ongoing study they note that:
Estuaries are special bodies of water occurring when the sea extends inland and meets the mouth of a river or streams. The estuaries of Southeastern Massachusetts – the harbors and bays of Cape Cod, Buzzards Bay and the Islands – are ecosystems that provide home and habitat for shellfish and sea grasses and breeding grounds for important commercial offshore marine fisheries. Rapid population growth over several decades has created an abundance of nutrients that have leached into the estuaries through ground and surface waters. Nutrients, such as phosphorus and nitrogen, act as a fertilizer to aquatic plants. The result: changes in water quality and the buildup of invasive weed and algal growth causing fish kills, closed beaches, destroyed productive shellfish areas and creating aesthetically displeasing waters that adversely affect the valuable tourist industry and coastal property values.
Lagoon Pond is one of the ponds that has been and is being studied. No report is yet available but each year twenty sites are chosen for the completion of a report.
