On the afternoon of May 8, 2024, DC Water issued a precautionary boil water advisory for a large swath of Northwest Washington, DC after a 20-inch water main broke and dropped system pressure below 20 psi. American University closed all campus dining facilities and suspended catering at its main campus, Washington College of Law, and the 4200 Wisconsin Ave building until water quality could be confirmed. The advisory was lifted on Friday, May 10, 2024, after two consecutive days of water tests showed no bacterial contamination.

American University has been included in DC Water's precautionary boil water advisory affecting multiple neighborhoods in Northwest Washington. The advisory covers the main campus, Washington College of Law, and 4200 Wisconsin Ave. To support the safety of our campus, Campus Dining has closed all dining facilities until further notice, including catering services. Do not drink, brush your teeth, or prepare food with tap water. Use bottled water or boil water before consuming. We will update you when the advisory is lifted.

The closure of all dining facilities on a residential campus -- not just public water fountains -- signals how seriously AU treated the 20-psi pressure drop that triggered the advisory.
The advisory came near the end of the spring semester, a period when residential dining halls are critical for students finalizing coursework.

DC Water requires two consecutive clean sample days before lifting a boil advisory after a pressure-related event -- the two-day gap between the break and the all-clear is standard protocol.
The source URL for the all-clear memo is available on the official AU Finance memos page, confirming the May 10 lift date.
Context

Background

The May 8, 2024 DC Water boil advisory traced to a break in a 115-year-old 20-inch water main. DC Water reported the break caused pressure to drop below 20 psi across a large portion of Northwest DC, including the neighborhoods of Upper Chevy Chase, Friendship Heights, Spring Valley, American University Park, Palisades, and portions of North Cleveland Park and Chevy Chase. Federal regulations require issuing a precautionary boil water advisory whenever pressure drops below 20 psi in a distribution system, because low pressure can allow bacteriological contaminants to enter through pipe cracks and joints. American University's main campus, Washington College of Law, and the 4200 Wisconsin Ave building were all included in the affected zone, covering the full institutional footprint. Campus Dining closed all facilities rather than attempt to manage limited water use during an advisory. DC Water completed emergency repairs on the main, conducted two consecutive days of water quality tests, and officially lifted the advisory on May 10, 2024. No illnesses were reported. The incident highlighted the vulnerability of major private universities embedded in aging urban water infrastructure.
