CHESTER COUNTY, Pa. (CBS) – There are two separate advisories this morning in Chester County, advising residents of two areas to boil their drinking water.

One is in East Brandywine Township, the other is in parts of Upper Uwchlan and West Vincent Townships.

They incidents are unrelated, but both are caused by a chlorine equipment failure, according to Aqua Pennsylvania spokeswoman Donna Alston.

“Basically that means that the disinfectant in the water wasn’t as high as we’d like to see or as high as required, so out of an abundance of caution we issued a boil-water advisory until we could actually get two consecutive bacteriological samples that would confirm that there is no threat to the water supply,” she told KYW Newsradio on Tuesday morning.

Alston says water for drinking, cooking, or brushing teeth should be boiled for at least one minute.

She stresses it is just a precaution, and expects the advisory to be lifted by Wednesday.  She says any of the approximately 1,000 affected customers should receive an automated phone call when the advisory is lifted.
