Our Mission

MassBays is an EPA National Estuary Program dedicated to protecting, restoring, and enhancing the estuarine resources of Massachusetts and Cape Cod Bays. We envision a network of healthy and resilient estuaries, sustainable ecosystems that support the life and communities dependent upon them. We facilitate partnerships to prompt local, state, and federal action and stewardship, convening stakeholders on the local and regional level, providing scientific basis for management decisions, and informing decision makers about problems and solutions.

MassBays National Coastal Condition Assessment RFR

The Massachusetts Bays Program (MassBays) is seeking proposals for a contractor to conduct water quality and sediment monitoring along the entire Massachusetts coast. This monitoring is for the U.S. Environmental Protection Agency’s (EPA) 2015 National Coastal Condition Assessment, a nationwide monitoring effort that takes place every five years. MassBays is managing the current effort for Massachusetts. The selected contractor will be tasked with collecting water column and benthic grab samples from 52 stations along the Massachusetts coast during the summer of 2015. All training and most supplies will be provided and sample analysis will be conducted by EPA. For more information, to view the Request for Responses, and download required forms, see the COMMBUYS website. Applications are due by February 20.
