Boil Water Advisory - April 1, 2019 

The Washington Suburban Sanitary Commission has issued a precautionary BOIL WATER ADVISORY for a portion of southern Prince George’s County.  It is anticipated to last through April 2, 2019. 

WSSC’s boil water advisory is for the area west of MD 210 (Indian Head Highway) to the Potomac River, and from the Washington, D.C. line south to Piscataway Creek. There are also small areas just east of MD 210 that are also under the boil water advisory.

WSSC has an interactive map to help customers find out if they are located in the affected area by typing in their address. WSSC has additional information about the water main break and what the boil water advisory means for residents.

During the Advisory:

  • Businesses in the impacted areas that prepare and serve food and water must shut down until the boil water advisory is lifted, unless those businesses have a separate water filtration system that serves the facilities’ entire water system, or if those businesses have an emergency operation plan that provides an alternative source of potable water.
  • If you live in the affected area, you should bring your water to a rolling boil for three minutes then cool it before:
    • Drinking
    • Brushing teeth
    • Washing fruits and vegetables

  • Do not wash food that is to be served raw with water that has not been properly disinfected.  
  • Disinfect water for the possible presence of harmful bacteria or other harmful micro organisms by one of the following methods:
