Where your water comes from, and what's in it
Two water systems, three sources, and a report every year since 2013. The 2025 reports list no violations for either system.
Three sources, two systems
The Ligonier Township system (PWSID 5650080) draws from the reservoir and the Gamelands well, and now also uses the Waterford well for its main supply. The Waterford system (PWSID 5650037) draws from its own well.

What a boil-water advisory means
An advisory goes out when there's a chance germs got into the water, usually after a main break or a loss of pressure. It's a precaution while we test. If one is issued, you'll get a call from 724-238-7464 and see it at the top of this site.
