WASHINGTON (7News) \u2014 The Potomac River<\/a> has been named the most endangered river in the United States, according to a new report<\/a> from American Rivers, citing a massive sewage spill<\/a> and growing concerns over data center<\/a> development.<\/p>\n

The designation follows a historic incident<\/a> earlier this year in which more than 250 million gallons of raw sewage spilled into the river, raising alarms about water quality and public health.<\/p>\n

Pat Calvert, Virginia director of conservation for American Rivers, said the spill represents a major setback after decades of environmental progress.<\/p>\n

\u201cGenerations of improvements to the health of the Potomac have been made, but an event like this can pose an acute challenge,\u201d Calvert said.<\/p>\n

Infrastructure Under Pressure<\/p>\n

The report highlights aging water and sewage infrastructure as a key vulnerability \u2014 not just in the D.C. region, but nationwide.<\/p>\n

Advocates are urging Congress to reauthorize federal programs that help local governments maintain and upgrade stormwater and wastewater systems. Without continued funding, officials warn similar incidents could happen again.<\/p>\n

Growing Impact of Data Centers<\/p>\n

Beyond the sewage spill, conservationists say the rapid expansion of data centers across Northern Virginia is placing additional strain on the region\u2019s water resources.<\/p>\n

Facilities require large volumes of water for cooling and energy production, which can stress already limited supplies amid population growth, extreme weather, and existing contamination concerns.<\/p>\n

Calvert also raised concerns about chemicals used in cooling processes, including biocides and so-called \u201cforever chemicals,\u201d which could enter waterways if not properly managed.<\/p>\n

\u201cThere needs to be transparency and a cumulative assessment of how these facilities impact water supplies,\u201d he said.<\/p>\n

Why the Potomac Matters<\/p>\n

The Potomac River serves as a vital resource for more than six million people across Washington, D.C., Maryland, Virginia, and West Virginia. It provides drinking water for the nation\u2019s capital and supports major ecosystems and industries.<\/p>\n

The river is home to important fisheries, including oysters, blue crabs, and striped bass, and has long supported Indigenous communities and regional economies.<\/p>\n

Signs of Progress<\/p>\n

Despite the concerns, advocates point to some recent progress.<\/p>\n

Virginia officials have approved new legislation requiring data centers to report water usage to regulators \u2014 a move aimed at increasing transparency and improving oversight.<\/p>\n

Environmental groups say more comprehensive, region-wide analysis is still needed to understand the cumulative impact of development.<\/p>\n

Call for Action<\/p>\n

Conservationists are calling on federal and state leaders to act quickly to protect the river.<\/p>\n

Key priorities include upgrading infrastructure, improving oversight of data centers, and ensuring long-term water quality protections.<\/p>\n

\u201cWe need to make sure we don\u2019t slide backward on the progress that\u2019s been made,\u201d Calvert added.<\/p>\n","protected":false},"excerpt":{"rendered":"WASHINGTON (7News) \u2014 The Potomac River has been named the most endangered river in the United States, according…\n","protected":false},"author":2,"featured_media":585260,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[47],"tags":[192,79],"class_list":{"0":"post-585259","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-environment","8":"tag-environment","9":"tag-science"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/585259","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=585259"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/585259\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/585260"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=585259"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=585259"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=585259"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
