Pennsylvania American Water on Tuesday called on residents of several communities in Chester and Lancaster counties to boil tap water after a burst water main in the borough of Parkesburg put the system at risk of contamination. .
The advisory applies to approximately 300 customers in the Borough of Parkesburg and some customers in parts of the Borough of Atglen in Chester County and Bart Township in Lancaster County.
Pennsylvania American, a subsidiary of American Water Works Co. Inc. of Camden, said a water main break caused a loss of positive water pressure, which “is a signal of the existence conditions that could allow contamination to enter the distribution system through backpressure or backsiphonage.
Guests are advised to use boiled or bottled water for drinking, making ice, washing dishes, brushing teeth and preparing food until further notice. Water should be brought to a boil on a stove for one minute, then allowed to cool before using.
The company said it was working to repair the main break. He made bottled water available to the Keystone Fire Department, 329 W. First Ave., Parkesburg.
Under state regulations, the company will collect and test water for bacteria. Two consecutive days of “clean” test results are required before the Pennsylvania Department of Environmental Protection allows the advisory to be lifted. (Test results take 18 to 24 hours to come back from the lab, so it can take several days for an advisory to be lifted.)
