As PAW was monitoring the conditions of the distribution system, they experienced a loss of positive water pressure due to a main break in Lower Merion Township. A loss of positive water pressure is a signal that could allow contamination to enter the distribution system, which means there’s an increased chance that the water may contain disease-causing organisms.

PAW recommends using boiled or bottled water for drinking, making ice, washing dishes, brushing teeth, and food preparation until further notice.

Inadequately treated water may contain disease-causing organisms, which can cause nausea, cramps, diarrhea, and headaches. If you experience any of these symptoms and they persist, you may want to seek medical advice.

PAW is currently working to repair the main break. The company is also collecting and analyzing additional water quality samples, including bacteria samples.
