EXCLUSIVE: Congress Expands Investigation Into DC Sewage Crisis

Congress expanded a probe into the Potomac Interceptor sewage spill by demanding to look at negotiated repair contracts between DC Water and a construction company, according to a letter obtained exclusively by The Daily Caller News Foundation.

Republican House Committee Chairmen Brett Guthrie, John Joyce and Gary Palmer sent a joint letter to Garney Companies, Inc. CEO, David Burkhart, to obtain information regarding the two-year Potomac Interceptor (PI) rehabilitation contract arranged between Garney and DC Water. DC Water was negotiating an Emergency Master Service Agreement with Garney, set to begin on May 15, 2025, which was never finalized, according to the letter.

“The collapsed portion of DC Water’s PI sewer line has resulted in what has been called ‘one of the largest sewage spills in U.S. history,’ said Guthrie, Palmer, and Joyce in a joint statement. “The consequences of this spill continue to be evaluated, and the Committee remains concerned by the potential impacts to public health, safe drinking water, the environment, interstate commerce, and tourism. The resilience of our wastewater infrastructure systems remains critical, and the Committee aims to understand what risks were determined prior to this incident and how future incidents may be prevented.”

The purpose of the contract between DC Water and Garney was stated to provide program management, preconstruction and emergency construction services to rehabilitate the Potomac Interceptor and do a number of repairs and upgrades to help with the PI’s reliability, according to the letter.

The House Committee requested Gareny provide all documents and communications related to their proposal submitted to DC Water, the unimplemented Emergency Master Service Agreement contract and information about the PI’s collapse site to understand what risks were known before the spill occurred.

Burkhart did not immediately respond to The Daily Caller News Foundation’s request for comment.

A section of the PI collapsed on Jan. 19, leading to 240 million gallons of sewage being pumped into the Potomac River, according to reporting by the Potomac Conservancy. Water samples showed dangerous levels of E. coli contamination in the water, 60 times higher than what is considered safe for human consumption, while other reports suggested the real levels were 100 times worse than initially suggested.

Potomac Riverkeeper Dean Naujoks pointed to infrastructure failure for the incident and expressed skepticism about the effectiveness of DC Water’s efforts to help maintain and clean up the PI’s spillage.

President Donald Trump announced in February that the federal government would intervene to assist in the Potomac River’s cleanup and said the Federal Emergency Management Agency (FEMA) would play a key role in coordinating the response. The president blamed the PI’s rupture on the “Gross Mismanagement of Local Democrat Leaders, particularly, Governor Wes Moore, of Maryland,” in a Truth Social post.

The Environmental Protection Agency (EPA) Assistant Administrator for Water, Jessica Kramer, announced on March 18 that wastewater flow was restored to the PI on March 14. Kramer stated that while restoring wastewater flow to PI is a significant milestone, the EPA “will be on the ground, working at full speed, until the site and surrounding area are fully remediated.”
