Mission and Program Overview

Mission

We are members of the waterkeeper alliance, an international organization with more than 350 riverkeepers as members. We have 3 riverkeepers, the upper potomac, the potomac, and the shenandoah, who work to protect 14,700 square miles of watershed, which provides recreational opportunities and serves as the drinking water source for almost 6 million people. Riverkeepers are the experts in their rivers, their eyes and ears, their voice, their advocates. Riverkeepers protect the public's right to clean water through assessment, advocacy, and enforcement. We step in to stop pollution when others fail to do. We leverage more than $1 million in pro bono legal services every year

To stop pollution and to restore clean water in the Potomac and Shenandoah rivers and their tributaries through enforcement and community engagement.

IRS990/Desc0Watershed Protection - We identify sources of pollution and analyze how to stop them. We regularly patrol the rivers we work to protect. We respond to tips and complaints. We review public records - like discharge monitoring reports and inspection reports to assess whether violations have occurred. We collect evidence water quality samples, photographs, videos, victim interviews- and build the case we need to stop the pollution and enforce the law. And we organize - we listen to communities along the river and work with them to stop the problems about which they care the most. We build grassroots support for clean water through stewardship, including our on-the-water paddle series: Riverpalooza.

IRS990/ProgSrvcAccomActy2Grp/Desc0Shenandoah: We upgraded our monitoring equipment for toxic algal outbreaks so we dont have to rely on the state to determine when and where they occur. We filed multiple algae complaints with the Commonwealth to encourage the state to monitor for algal outbreaks. We organized a cleanup with 16 partner organizations of 62 sites on Earth Day, removing 60 tires and 200 bags of trash from the Shenandoah River System. We renewed our internship program with four universities: Shenandoah University, Howard University Law School, Trinity University, and Hood College. We also expanded partnerships with community groups led by people of color for stopping pollution, reducing public health risks to communities, and increasing recreational access programs.

IRS990/ProgSrvcAccomActy3Grp/Desc0Upper Potomac: We expanded our investigation and awareness campaign for PFAS (forever chemicals), including partnering with USGs on testing PFAS levels in fish tissue and blood and partnering with faculty at Frostburg State. We expanded our community science water quality monitoring program in partnership with Hood College to test for conventional pollutants and also acid mine drainage.
IRS990/ProgSrvcAccomActy3Grp/ExpenseAmt0111913
IRS990/ProgSrvcAccomActyOtherGrp/Desc0Lower Potomac: We pursued our Trash-free Potomac Campaign with volunteer trash cleanups in Alexandria, National Harbor, and Oxon Run and participated in efforts to pass legislation to reduce the sources of plastic pollution. We expanded our community science water quality monitoring on the Potomac River in DC, Maryland and Virginia. We expanded our 50 Million Mussels Campaign at National Harbor. We worked with Congresswoman Norton to fund a study by The Army Corps of Engineers to assess where swimming can safely occur in the rivers in DC. We brought litigation against the city of Alexandria for unpermitted discharges of coal tar and creosote into the river and litigation against the navy for more than 100 years of unpermitted discharges of munitions into the Potomac River, including the critical habitat of the endangered atlantic sturgeon. We worked with Maryland legislators to increase funding for inspection and enforcement personnel to protect Marylands waterways.
