WSSC Lifts Recreational Water Contact Health Advisory for T. Howard Duckett Reservoir

Recreational Water Contact Health Advisory Remains for Triadelphia Reservoir

| News Release



Drinking Water Not Affected

Laurel, Md. – September 20, 2019 – After two weeks of extensive monitoring and testing showed algal concentrations below advisory thresholds, WSSC today lifted the second recreational water contact health advisory of the summer for their T. Howard Duckett Reservoir in Laurel. The advisory was reinstated on September 6 as a precaution following the detection of high concentrations of blue-green algae, which can cause serious adverse health effects if contacted.

The recreational water contact health advisory remains in effect for the Triadelphia Reservoir. Due to ongoing dam rehabilitation work at this reservoir, this area is not open to the public. All recreation areas, boat ramps and public access are closed.

However, if you come in contact with the water at the Triadelphia Reservoir you should do the following:

  • Rinse off immediately with clean water.
  • Do not allow pets to swim in or drink the water (prohibited at all times by WSSC watershed regulations).
  • Do not consume fish livers or digestive organs from fish caught in the reservoir. If a fish is caught in the reservoir, wash fillets thoroughly with drinking water.

In the event that you, your pet, or someone you know has contacted or ingested water at the Triadelphia Reservoir, call your local Health Department:

  • Montgomery County: 240-777-0311 (Montgomery County 311)
  • Prince George’s County: 301-883-4748 (Prince George’s County 311)
  • Howard County: 410-313-1773 (Community Hygiene Department)

Both reservoirs, located along the Patuxent River, serve as drinking water sources for WSSC and recreational areas for hiking, fishing and boating. It is important to note, WSSC’s drinking water is not affected by the recreational health advisory and continues to meet all Safe Drinking Water Act standards. As a precaution, WSSC is closely monitoring water quality conditions at its Patuxent Water Filtration Plant.
