In celebration of Earth Week, RHA volunteers come together to clean up our rivers and streams, working to protect essential water supplies across Hunterdon, Morris, and Somerset counties.

RHA’s three-hour effort from its volunteers reaches beyond our watershed region – the cleanup provides safe access for residents to experience the benefits of outdoor recreation and positively impacts downstream to Raritan Bay and ultimately, the Atlantic Ocean.
