Health and environmental officials are issuing urgent warnings after a massive spill of untreated sewage entered the Potomac River. The significant release of raw wastewater has raised immediate concerns about water quality and public safety along the iconic waterway.

The incident has prompted advisories against any contact with the affected sections of the river. Authorities specifically warn against swimming, wading, or participating in water sports. The public is also cautioned to ensure pets do not enter the contaminated water.

Medical experts emphasize the serious health risks posed by such contamination. Exposure to the polluted water can lead to a range of illnesses, including severe gastrointestinal infections, skin rashes, respiratory issues, and infections of the eyes and ears. The pathogens present in raw sewage pose a particular threat to children, the elderly, and individuals with compromised immune systems.

Environmental teams are actively assessing the full scope of the spill and its downstream impact. Officials stress that the warnings will remain in effect until comprehensive water testing confirms that bacterial levels have returned to a safe standard. Residents are urged to heed all posted advisories and avoid the river until further notice.
