This is about 8 miles south of Washington,DC and feeds directly into the Potomac River. No health concern BUT stay out of the water. I hope it is diluted by the time it gets to us 70 miles down river.Jim--------------LAUREL, Md. -- Authorities said power is back up at a Prince George's County pumping station where more than 1 million gallons of wastewater overflowed after electricity outages.Authorities said power went out at the Broad Creek Pumping Station in Fort Washington on Saturday during severe thunderstorms.That outage caused about 1 million gallons of untreated, diluted wastewater to run off into Broad Creek.Another outage occurred early Sunday as Pepco crews were working at the site, prompting another sewer overflow. It was unclear how many gallons seeped out.John C. White, spokesman for the Washington Suburban Sanitary Commission, said there are no health concerns at this point, but signs are posted in the area warning people to stay out of the affected waters for 30 days.
