Data sets for some indicators takes time to become publicly available, so … Based on data from 2018 and 2019, heavier-than-average rainfall likely played an outsized role in the outcome, too. What are PCBs and why are they harmful? The safety of the river can change daily depending on … Unfortunately, much of what our local rivers and streams experience is excessive channel erosion, which can have harmful effects on water quality and wildlife.

Though PCBs have not been manufactured in the United States since they were banned in 1979, they are still polluting our rivers and streams decades later because the chemicals do not break down easily. The Potomac Conservancy, which released the 2020 Potomac River Report Card, said more polluted runoff from urban and suburban areas and fewer trees to slow and filter rainfall were among the factors causing the grade to slip. Options include digging up and removing the affected sediment or covering the affected sediment with a clean replacement. People and the Planet Who Polluted the Potomac? The cleanup plan includes goals for the reduction of nitrogen, phosphorus, and sediment in the Potomac and other Bay rivers by setting a pollution limit, called a total maximum daily load (TMDL), by state and source. Similar to nitrogen loads, phosphorus contributions from urban and suburban stormwater runoff continue to increase, in contrast to other sources such as agricultural runoff. Upper Potomac Riverkeeper Brent Walls stands in the North Branch of the Potomac River at the wastewater outfall that served the Luke, MD, paper mill owned by Verso Corporation. For many thousands of years, people have lived on the banks of the Potomac River.

Good we made progress since then. You will receive our next monthly River Update e-newsletter. Removal of streamside vegetation also exposes streambanks to increased erosion. It's amazing something so natural can do that. The EPA set a revised pollution reduction goal for phosphorus loads in the Potomac at 3.898 million pounds per year by 2025. While the Potomac River is clearly not what the Washington Post in 1951 called an “open sewer,” for the first time in a decade, the river’s health has declined, reported the Potomac Conservancy last month, falling from a grade of B to B- and still unsafe for swimming or fishing.

The EPA set a pollution reduction goal for sediment loads in the Potomac at 2.26 billion pounds* per year by 2025. “It's definitely safe to swim in the Potomac on a perfect summer day,” said Phillip Musegaas, vice-president of programs and litigation for the Potomac Riverkeeper Network. Poorly planned development increases the amount of pavement and decreases the amount of natural land cover. In fact, natural erosion can actually improve habitats. USGS non-tidal flow normalized testing observed 4.02 million pounds of phosphorus in 2018. Many of the PCBs found in the Potomac and other local waters originated years ago. With D.C.’s famous monuments in sight, the Potomac has been deemed by many “the nation’s river,” and it serves a much larger purpose than you might realize. Some degree of channel erosion occurs naturally. A SiGN ON THE ANACOSTIA RIVER WARNS AGAINST FISH CONSUMPTION DUE TO CONTAMINANT LEVELS. They hunted in the forests, harvested foods from wetlands, and caught fish in the river. Polluted runoff can carry pesticides and plastics into the Potomac when it rains. Eventually, the trash flows into the Chesapeake Bay and ultimately, the Atlantic Ocean. Channel erosion is the process by which the banks (aka the channel) of a river or stream erodes away. Human population growth impacts water sources because .
