Raw sewage recently spilled from a burst water main near Philadelphia, Pa., sending several million gallons of untreated waste into Valley Creek. The incident started on March 18 and the spill was not contained until 30 hours later, the Philadelphia Inquirer reported.
According to sources quoted by 6ABC, the total amount of sewage that spilled into the creek, close to Valley Forge National Historical Park, was over 5 million gallons. Officials explained that the rupture was detected several hours after wastewater started to gush out into the creek but when eventually the flow was turned off, sewage went back to the pumping station near Wilson Road in Chesterbrook, contaminating a trout stream in the national park.
This is not the first such incident in the Valley Forge National Historical Park sewage system. About two months ago there was another break around the same section of pipeline and an earlier one occurred two years ago, the Inquirer said. The pipeline was installed in the early 1970s. During the latest cleanup process, ductile iron pipe replacements for sections of the pipe were fitted.
The state Department of Environmental Protection said there was no threat to drinking water supplied in the area but there could be environmental risks, particularly since it was the trout's egg-laying season, reports noted.
