Sharon Water Hardness & Quality Report (2026)

Aqua Pennsylvania, Inc. draws all its water from the Shenango River, a surface source serving about 25,000 residents in Sharon, Pennsylvania, and surrounding areas in Mercer County. The utility's water originates in a 650-square-mile watershed north of the city, flowing through Paleozoic sedimentary formations. Treatment takes place at the Shenango Valley Water Treatment Plant, a facility that employs conventional methods like coagulation, sedimentation, filtration, and disinfection to meet basic EPA standards for turbidity and microbes. This plant serves neighborhoods near Buhl Park and communities throughout the Shenango Valley region.

The Shenango River watershed is characterized by Paleozoic sedimentary rocks, including significant deposits of limestone, shale, and sandstone. These rock types, particularly the limestone-rich Pennsylvania geology, readily dissolve minerals such as calcium and magnesium into the river's flow. Connected underground aquifer systems also contribute to the water's mineral content by leaching ions from fractured sedimentary layers. This limestone-dominated geology is responsible for the water's moderately mineralized character, resulting in a harder water profile compared to supplies from softer, granitic or glacial terrains.

This moderately hard water can lead to scale buildup in appliances like water heaters, dishwashers, and washing machines, potentially reducing their efficiency and lifespan. You might notice diminished soap lathering, requiring more detergent for cleaning, and spotting on glassware and fixtures. Homeowners can manage scale by regularly descaling showerheads and faucet aerators with vinegar and flushing water heaters at least twice a year. Installing a whole-house water softener is often recommended to prevent appliance damage, extend the life of your equipment, and improve overall cleaning effectiveness.
