Boil water advisory issued for hundreds of thousands of people

The Pittsburgh Water and Sewer Authority issues a precautionary boil water advisory for about 100,000 of its’ customers Tuesday.

The Pennsylvania Department of Environmental Protection found problems at Highland Park drinking water filtration plant.

According to the Pittsburgh Post-Gazette, the problem is related to possible Giardia contamination, which is a parasite that can cause diarrhea, according to the Center for Disease Control and Prevention.

The PWSA issued a statement saying in part, “The temporary advisory is the result of recent disinfection and chlorine testing taken at a single location near the Highland Park drinking water filtration plant. A few tests showed low levels of free chlorine in the treated drinking water. PWSA is coordinating with the Pennsylvania Department of Environment (DEP) to ensure that all regulatory requirements for disinfection are met immediately. ”
