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. 305656 Shenandoah: 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. 141071 Upper 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. 76502 Lower 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. 76502 1577782 true true false false false false false false false false true false false true false true true false false false false false false false true false false false false true false false false false false false false false false false false false false false false false false true 25 0 true 13 true false false false false true true true true false false false false false X 18 18 false false false false false false false true true false false true true true true true true false false false DC MD PA VA WV X X Potomac Riverkeeper Network 2028882037 3070 M Street NW Washington DC 20007 Nancy Stoner President 40.00 0.00 X 207013 0 22002 Emily Franc Development Director 40.00 0.00 X 135274 0 15729 Elizabeth Nicholas VP of Programs 40.00 0.00 X X 124502 0 14182 Dean Naujoks Lower Potomac Riverkeeper 40.00 0.00 X 108645 0 14048 CJ Gross Director 1.00 0.00 X 0 0 0 Rick Peterson Director 1.00 0.00 X 0 0 0 Brenda Richardson Director 1.00 0.00 X 0 0 0 Frank Filipy Director 1.00 0.00 X 0 0 0 Sally Davidson Director 1.00 0.00 X 0 0 0 Ethan Landis Director 1.00 0.00 X 0 0 0 Carol Ackerman Director 1.00 0.00 X 0 0 0 Katherine Edwards Director 1.00 0.00 X 0 0 0 Viveca Novak Director 1.00 0.00 X 0 0 0 Peter Bross Director 1.00 0.00 X 0 0 0 David Hunke Director 1.00 0.00 X 0 0 0 Laura Carpenter Director 1.00 0.00 X 0 0 0 Anthony Bing Wu Director 1.00 0.00 X 0 0 0 Tim Hill Director 1.00 0.00 X 0 0 0 Greg Parrilli Treasurer 2.00 0.00 X X 0 0 0 Randy Benn Chair 2.00 0.00 X X 0 0 0 Shelley Slade Vice Chair 2.00 0.00 X X 0 0 0 Pat Munoz Secretary 2.00 0.00 X X 0 0 0 575434 0 65961 4 false true false 4379 1385488 10439 1389867 Program Fees 900099 15087 15087 15087 30516 30516 285505 4379 153595 131910 131910 Other 900099 15522 15522 15522 1582902 30609 0 162426 X 207013 154945 14346 37722 806760 603844 55910 147006 23603 17666 1636 4301 124092 92880 8600 22612 89047 66650 6171 16226 19379 19355 24 57687 57687 216494 200814 15680 7182 1230 5952 94340 67747 10415 16178 121719 107753 8435 5531 36471 31193 3493 1785 35227 34001 1023 203 67813 60031 4701 3081 31805 29813 1992 Dues and Subscriptions 27101 8584 18382 135 Boat expenses 23589 23589 1989322 1577782 141080 270460 316766 324367 743646 554620 83200 25585 11578 30640 462783 398871 114703 63912 1003780 921480 2273673 1920604 90027 143378 90027 143378 X 1183830 895044 999816 882182 2183646 1777226 2273673 1920604 -406420 0 X false true X true false X 1292484 1362382 2611574 1396739 1389867 8053046 1292484 1362382 2611574 1396739 1389867 8053046 894972 7158074 6426 1582 1553 10404 30516 50481 24186 18594 67650 12886 15522 138838 8242365 0.86840 0.91600 X RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED 19770 19770 443013 379101 63912 63912 Pledge Receivable In-Kind Rent 915480 Security Deposit 6000 921480 X 3115956 1379459 153595 1533054 1582902 1582902 3522376 1379459 153595 1533054 1989322 1989322 Endowment funds intended uses (Part V, line 4) The Board of Directors of the organization has designated a portion of unrestricted net assets as a reserve fund.
