GREENSBURG, Pa. (AP) — The first of two tests needed to lift a drinking water alert affecting 120,000 western Pennsylvania residents has come back positive.
If results of a second test are OK, the boil water advisory issued Friday by the Municipal Authority of Westmoreland County will be lifted.
Residents in communities along the Kiski River in Westmoreland County have been advised to boil their water because a faulty filter might have allowed water tainted with dangerous algae to contaminate its entire supply.
Officials say water used for drinking, making ice, brushing teeth, washing dishes and preparing food should be boiled for a minute and then cooled.
Sunday's encouraging test results were based on water samples taken Saturday. If samples taken Sunday produce the same results on Monday, the advisory will be lifted.
