Well water in Berks County

Berks County water: common questions
Is Berks County water hard?
Often, yes. Much of Berks County sits on limestone and dolomite, which adds hardness minerals to groundwater. Pennsylvania American Water's Penn District, which supplies Sinking Spring, averaged 204 to 360 mg/L in 2025, far above the 120 mg/L that Penn State Extension considers hard. Hardness varies by utility and by well, so a test is the only way to know your number.
Who supplies my water?
It depends on where you live. Berks County's water system table lists Pennsylvania American Water (Penn District) for Sinking Spring and parts of Spring and Cumru townships, Western Berks Water Authority for Wyomissing, West Reading, Shillington, Mohnton and parts of Spring and Cumru, and the Wernersville Municipal Authority for Wernersville and Lower and South Heidelberg townships. Your water bill names your supplier. Many rural homes are on private wells.
Should I test my well?
Yes. Pennsylvania has no statewide testing requirement for private wells. In Penn State's lab summary of Berks County samples, 40.2% failed for total coliform bacteria. We test hardness, iron, manganese, pH, chlorine and TDS for free and help you arrange a certified lab test for bacteria and lead.
