❓WHAT HAPPENED: A sewer pipe collapse has released an estimated 250 million gallons of raw sewage into the Potomac River in Washington, D.C., impacting a large swath of the waterway.
👤WHO WAS INVOLVED: D.C.’s Department of Energy and Environment, DC Water, capital residents, and environmental advocates.
📍WHEN & WHERE: The incident occurred on January 19, near Cabin John, Maryland, with several additional spills in the following weeks, before the ongoing flow of raw sewage was diverted into a nearby canal.
💬KEY QUOTE: “It’s going to have a profound impact on the river beyond what I think anybody can imagine.” – Dean Naujoks of the Potomac Riverkeeper Network
🎯IMPACT: The spill affects recreation, wildlife, and the local economy, with high E. coli levels and potential long-term environmental damage.
Nearly a month after a sewer pipe collapse, an estimated 250 million gallons of raw sewage have been released into the Potomac River, leading to significant environmental and recreational concerns. The collapse initially occurred on January 19 near Cabin John, Maryland, about seven miles north of Georgetown, and released approximately 40 million gallons of raw wastewater into the river daily. Some experts believe the spill is now the most significant unintentional release of untreated sewage in U.S. history.
Despite initial efforts to get the spill under control, officials acknowledged setbacks, including subsequent sewage releases into the Potomac River. Even more troubling is that the flow through the broken sewer pipeline, which runs below the river between Virginia and Maryland, is currently being diverted into a segment of the historic Chesapeake and Ohio Canal (C&O Canal), creating an open-air sewer channel that itself is quickly becoming an environmental hazard.
The crisis has forced the District of Columbia’s Department of Energy and Environment to issue a warning to residents of the capital to avoid contact with the river, advising against fishing, boating, and allowing pets near the water. Despite the spill, officials claim that drinking water remains safe, as tap water is sourced upstream from the spill.
Dean Naujoks of the Potomac Riverkeeper Network warns that the spill is “going to have a profound impact on the river beyond what I think anybody can imagine.” Notably, spot tests just downstream of the spill have shown E. coli levels near the site to be significantly higher than the U.S. Environmental Protection Agency (EPA) limits for swimming. Officials have also detected bacteria linked to staph infections and MRSA.
Concerningly, local government leaders in D.C., Maryland, and Virginia have suggested the spill is unlikely to be resolved before the end of the year. This means a large section of the Potomac River in the heart of the nation’s capital is unlikely to be safe for recreational use, including boating, swimming, or fishing, as the country is set to celebrate its 250th Anniversary later this summer.
