According to PA Department of Environmental Protection (DEP) guidelines, water samples must be collected to test for bacteria in the distribution system. The first samples are taken on the day when the issue (e.g. main break) has been corrected, and then another set of samples are taken in the next 24 hours. Two consecutive days of "clean" test results are required before DEP will allow the advisory to be lifted. (The process takes 24 hours for test results to come back from the laboratory, so final lab results to lift an advisory can take several days after the event.)
According to AWA General Manager Mike Dominick, "All good with yesterday's samples. Tomorrow around the same time (noon) we should get results on samples we dropped off today. "
"If those are clear (we have no reason to think they won't be), then I believe DEP will lift the boil advisory."
Dominic added that they are hoping to get the results at noon Thursday. The DEP will see results shortly thereafter and then will end or continue to boil advisory. Notice will be sent out to all media outlets to alert the public when boil is lifted.

What should I do once the advisory is lifted?
Customers under a precautionary boil water advisory can resume normal water usage when the notice is lifted without taking additional measures. If you experience cloudy or discolored water, you should run your faucets for a few minutes until the water runs clear.
Should I flush my house pipes?
The company will notify you if it necessary to flush household pipes and provide instruction for steps to take prior to using the water in the event of a mandatory boil water notice . Flushing simply means letting the water run to ensure that no contaminated water remains in your pipes. If customers are advised to flush household plumbing, follow these guidelines:
- Run all cold water faucets in your home for one minute at one time with the highest water flow possible to prevent splashing or flooding of the drains
- To flush automatic ice makers, make three batches of ice and discard
- Run water softeners through a regeneration cycle. Follow the manufacturer’s guidelines specified in the owner’s manual
- Run drinking water fountains for one minute at the highest flow rate possible
- Change refrigerator filters
