Project Clean Stream

Keeping our Parks and Streams Clean

Project Clean Stream, started in 2002, in partnership with local conservation groups, businesses and communities, is a Chesapeake seasonal clean up where local volunteers pick up trash from parks and streams and raise awareness about the importance of individual environmental stewardship.

Every year, tens of thousands of volunteers come together to pick up trash from local streams, creeks, rivers, parks, and neighborhoods as part of the Alliance’s Project Clean Stream! We provide supplies for cleanups anywhere in the Chesapeake Bay watershed (all 6 Bay states and the District). For events outside of the Lancaster area in PA- check out Keep PA Beautiful.  Looking for additional events in D.C., Virginia or Maryland? The Alice Ferguson Foundation hosts cleanup events for volunteers throughout the region. Visit their Cleanup Page to find additional events near you!

Through Project Clean Stream, the Alliance offers hands-on opportunities through our partnership with residents, local businesses, environmental organizations, local governments, community groups, houses of worship, schools and universities, to come together to take action to restore clean waters to local streams, creeks, and rivers. Volunteers have the opportunity to pick-up trash in their communities, discover how their everyday decisions affect the overall health of their local waterways, and ultimately foster a healthier and more sustainable relationship with the Chesapeake.

How it Works

The Alliance works with site captains to coordinate local cleanup events, and provides cleanup supplies such as trash bags and gloves.

Anyone can organize a cleanup, as long as the cleanup is located in the Chesapeake Bay watershed! If you organize a cleanup event, you will be responsible for picking up supplies (if needed) at one of our pick-up locations.
