(DC)(Rock Creek Conservancy) Join Rock Creek Conservancy, the National Park Service, and Blue Planet Scuba for a litter removal restoration at Picnic Grove #6 in Rock Creek Park. Trash is the visible form of stormwater pollution, a major threat to water quality and park health and its removal makes the parklands cleaner, safer, and more beautiful for all.
