Confirmed Threat

On July 3, 2024, DC Water issued a precautionary boil water advisory affecting the George Washington University Foggy Bottom and Mount Vernon campuses along with surrounding areas. Students and staff were instructed to discard any beverages and ice made after 9 p.m. on July 3 and to boil tap water before consumption. The advisory was lifted after testing confirmed that drinking water from the Washington Aqueduct never deviated from EPA water quality standards.

Discard any beverages and ice made after 9 p.m. on Wednesday, July 3, 2024. Run cold water prior to boiling. Bring water to a rolling boil for 1 minute and let it cool. Store cooled water in a clean, covered container.
Four sequential instructions framed as discard, prepare, boil, store — covers the entire user workflow in one short message
Specific timestamp (9 p.m., Wednesday, July 3, 2024) defines an exact contamination window for affected products
Instruction to 'run cold water prior to boiling' is unusual; reflects DC Water guidance on flushing the line before boiling
Distributed in the hours leading into the July 4 holiday, when most students were off campus but residential summer students remained

DC Water has confirmed that drinking water provided by the Washington Aqueduct never deviated from U.S. EPA established water quality standards.
Frames the resolution as a finding ('never deviated') rather than a corrective action — implies the advisory was overly cautious from the start
Cites DC Water as the authority and the Washington Aqueduct as the underlying water source — consistent with attribution to a non-university actor
No explicit 'tap water is safe' language; implied by the negation of a deviation
Context

Background

The July 2024 boil water advisory affected a large swath of Washington, D.C., including Arlington County, Virginia. For George Washington University, the advisory hit both its Foggy Bottom campus in the heart of D.C. and the Mount Vernon campus. The timing over the July 4th holiday weekend meant reduced campus population but also reduced staffing for response. DC Water's roughly nine-hour precautionary advisory was triggered when a green algae bloom clogged filters at the Dalecarlia Treatment Plant, the first city-wide boil-water warning for all of D.C. in nearly 30 years, though subsequent testing confirmed the Washington Aqueduct supply never fell below EPA standards. GW maintains a dedicated Campus Advisories website that served as the primary information hub during the event. This case illustrates how off-campus infrastructure events, in this case a municipal water system issue, can directly affect campus operations and require university-level communication even when the university itself is not the cause or the responder.
Analysis

Key Findings

Municipal infrastructure events like water system advisories can trigger campus alerts even when the university is not the source of the problem
Holiday timing reduces campus population exposure but complicates institutional response capacity
Precautionary advisories that are later fully cleared demonstrate conservative public health communication practices
Outcome
The boil water advisory was lifted after water quality testing confirmed the supply met all EPA standards. No illness reports were associated with the advisory.
