ARMSTRONG COUNTY, Pa. - Pennsylvania American Water has lifted its "do not use" warning and issued a precautionary boil water advisory for its approximately 2,100 Kittanning customers.PAW said the water treatment issues have been resolved, and the pH of the water is within normal ranges throughout Kittanning and nearby impacted areas. Before water is used for any purpose, PAW recommends that customers:
· Drain and refill the hot water heater · Flush the hot and cold water systems for at least five minutes · Discard any items that were made with water after 5 a.m. on November 16, 2012 PAW said it experienced a loss in positive water pressure on Friday due to the shut down of the Kittanning Treatment Plant in response to the elevated pH levels. A loss of positive water pressure is a signal of the existence of conditions that could allow contamination to enter the distribution system through backflow by back-pressure or back-siphonage. As a result, there is an increased chance that the water might contain disease-causing organisms. As a precaution and until further notice, the Kittanning customers are under a boil water advisory. PAW recommends not drinking the water without boiling it first.
