Project Clean Stream

Local Action for a Cleaner Chesapeake

Project Clean Stream (PCS) began in 2002 as a small partnership with local groups. Today, it is the largest cleanup effort in the Chesapeake Bay region! Last year, our volunteers removed over 12.5 tons of litter from our local parks, neighborhoods, and waterways like streams and rivers.

It’s easy to get involved and make an immediate environmental impact. We work with “Site Captains” to plan local events and provide free supplies, including trash bags and gloves. Anyone can become a Site Captain and lead a cleanup, as long as the event takes place within the Chesapeake Bay watershed.

Project Clean Stream will kick off on Friday, April 3, 2026
