COASTSWEEP, the state-wide beach cleanup sponsored by the Massachuseets Office of Coastal Zone Management (CZM) and the Urban Harbors Institute at UMass Boston, will kick off its 22nd year on September 19 at Nantasket Beach in Hull. Thousands of volunteers throughout Massachusetts turn out each year for this event, which is part of an international campaign organized by The Ocean Conservancy in Washington, DC. Participants all over the world collect marine debris and record what they find. This information is then used to help reduce future marine debris problems. Cleanups will be scheduled throughout eastern Massachusetts in September and October. To participate or organize a cleanup, go to the COASTSWEEP website.
