Barcaloungers, toilet bowls, rubber boots, pieces of fishing net, truck tires, industrial tubing, milk crates, vinyl siding, and thousands and thousands of cigarette butts are but some of the items found during Massachusetts COASTSWEEP cleanups.
COASTSWEEP is part of an annual event to raise awareness and clean beaches from Boston to Bimini. The International Coastal Cleanup organized by Ocean Conservancy brings hundreds of thousands of volunteers to beaches, lakes, and streams worldwide to remove marine debris (i.e., trash, fishing line, and any other human-made items) and collect data on what is found to help analyze and address this problem.
For a full list of information on the COASTSWEEP website, see Overview and Index.
Since 1987, volunteers in Massachusetts have been pitching in to clean up stretches of the shoreline as part of COASTSWEEP. This CZM event began with just 391 volunteers who collected almost two tons of debris along 40 miles of coast. The annual cleanup has grown over the years—in 2022, approximately 2,856 volunteers cleaned over 160 miles of coastline, river bank, marsh, seafloor, and lakeshore in eastern Massachusetts—collecting more than 18,197 pounds of debris from over 148 locations. COASTSWEEP cleanups are held from late August through November each year, with the focus being around the International Coastal Cleanup in September.
Common Marine Debris Items
Curious about what volunteers find at a typical cleanup? Analysis indicates that more than half of the items clearly come from land-based sources when litter is blown or washed directly into the ocean or into rivers, streams, and storm drains that run to the sea. Only about 10 percent of the marine debris is confirmed to be released from ocean-based activities, such as boating and fishing. But it all adds up to thousands of tons of trash littering the world's oceans and beaches. The table below shows the top 10 items found along the Massachusetts coast in 2022, which represents the typical types of debris commonly collected during COASTSWEEP.

Dedicated COASTSWEEP Volunteers
Thanks to the thousands of dedicated COASTSWEEP volunteers who get out there each year, literally tons of trash have been removed from Massachusetts shorelines. And each beach cleanup is headed by a particularly dedicated volunteer, the cleanup coordinator, who organizes all the action at one or more sites. See Become a COASTSWEEP Cleanup Coordinator or Volunteer for details.
Beyond Clean Beaches
COASTSWEEP is more than a beach cleanup. As part of COASTSWEEP, volunteers help address future problems by filling out data cards to show what they've collected. These cards are sent to Ocean Conservancy in Washington, DC, where the information is entered into a massive database. The data are then used to analyze the local and international trends in marine debris and identify its sources to help reduce the problem in the future.
Whether it is urban trash or abandoned fishing gear, marine debris is more than an eyesore—it can also directly harm sea life and humans. Sea birds, seals, and other animals can be choked, starved, or poisoned when they become entangled in or ingest debris. Sea turtles are particularly vulnerable and can die after swallowing clear plastic bags that they mistake for jellyfish. Beachgoers can injure themselves on sharp edges of glass or metal while walking on the sand or swimming, and boaters can become stranded when propellers are jammed with fishing line or cooling intakes are clogged with plastic.
