- Reason for Advisory:
- The advisory was prompted by concerns about cloudy water and the need to ensure an adequate water supply for potential firefighting during the holiday weekend.
- The increased algae bloom in the Potomac River led to clogged filters at the Dalecarlia water treatment facility, affecting water supply.
- Backup Measures: D.C. Water shifted to using the MacMillan treatment facility as a backup.
- Chemical Treatment: The aqueduct used additional chemicals (copper sulfate and sodium permanganate) to combat the algae and improve water flow.
- Lifting of Advisory:
- The boil water advisory was quickly lifted because regular testing indicated that the treated water never deviated from drinking water standards.
- This marked the first time in nearly 30 years that such an advisory was issued for all of D.C..
- Affected Areas:
- In addition to D.C., the advisory impacted nearly all of Arlington County, including the Pentagon, Arlington National Cemetery, and Reagan National Airport.
- Arlington County also confirmed that residents could safely drink tap water after the advisory was lifted.
