What that means for your home
It's very hard water. Penn State Extension calls anything over 120 mg/L (7 grains per gallon) hard. Every Penn District entry point averaged well above that in 2025.
Expect scale. Hard water leaves white crust on faucets and shower glass, spots on dishes and scale inside water heaters and dishwashers.
Chlorine is used to disinfect. It keeps the water safe in the pipes, but some families notice the taste and smell. A carbon filter removes it at every tap or just at the kitchen sink.
Homes on private wells around Sinking Spring
Many homes in the townships around Sinking Spring rely on private wells. Pennsylvania has no statewide rules requiring private wells to be built to a standard or tested, so the owner is responsible for the water.

Some neighboring areas are served by Western Berks Water Authority or the Wernersville Municipal Authority, and many homes outside the borough are on private wells.
Do I need a water softener on Sinking Spring city water?
Hardness at that level commonly leaves scale on fixtures and inside water heaters, so many homes benefit from a softener. A free in-home test tells us your actual hardness so the softener is sized correctly.
Can you help if I'm on a well near Sinking Spring?
Yes. We test and treat private wells for iron, manganese, sulfur smell, hardness, acidic water and bacteria. Bacteria and lead need a certified lab test, and we'll help you arrange one.
