Potomac River Declared Most Endangered Due to Data Centers and Aging Infrastructure

The Potomac River has been identified as the most endangered river in the United States, according to the nonprofit organization American Rivers. This designation stems from two primary threats: significant sewage pollution from aging infrastructure and an unprecedented surge in data center development in the river's vicinity.

The American Rivers report highlights the catastrophic failure of the Potomac Interceptor wastewater pipe in January, which resulted in the discharge of hundreds of millions of gallons of untreated sewage into the Potomac River and the Chesapeake and Ohio (C&O) Canal. This incident caused bacteria levels to exceed safe recreational limits by over 4,000 times at the closest monitoring sites. The Potomac Interceptor, over 60 years old, is emblematic of the aging infrastructure that poses ongoing risks to water quality.

In addition to sewage issues, the rapid expansion of data centers in Virginia and Maryland has raised concerns about their environmental impact. Currently, the region hosts over 300 data centers, with projections suggesting that this number could rise to approximately 1,000, covering around 200 million square feet of land. The report warns that these facilities threaten both water quality and quantity, as they require substantial water and energy resources.

American Rivers has called for urgent action, urging Congress to reauthorize infrastructure funding bills to facilitate upgrades to aging wastewater systems. The organization also advocates for state regulators to enforce transparency regarding data centers' resource consumption and to mandate comprehensive environmental assessments prior to approving new developments.

Critics of the current regulatory framework argue that the approval processes for data centers lack meaningful transparency and do not adequately assess cumulative environmental impacts. The report emphasizes that the rapid development of data centers is occurring without sufficient oversight, which could exacerbate existing pollution issues in the Potomac River.

While the American Rivers report provides a detailed account of the threats facing the Potomac River, it does not specify the exact number of data centers currently under construction or in the planning stages. Additionally, the report does not address potential mitigation strategies that data centers could implement to reduce their environmental footprint.

“The region currently has over 300 data centers and is on track to have a total of about 1,000 centers occupying roughly 200 million square feet of buildings — enough to cover 3,472 football fields — on an estimated 20,000 acres of land,” — American Rivers Report

“These facilities pose a significant and growing threat to both water quality and water quantity, yet are being approved without meaningful transparency, regulatory review, and assessment of cumulative impacts.” — American Rivers Report

“The Potomac Interceptor is over 60 years old, and is just one of many in the region that is at or past the 50-year service life, American Rivers notes.” — American Rivers Report

In light of these findings, American Rivers is advocating for legislative action to address the aging infrastructure and the environmental impacts of data centers. The organization is pushing for increased regulatory scrutiny and community engagement in the planning processes for future developments.
