New Kensington Water Hardness & Quality Report (2026)

The Municipal Authority of the City of New Kensington supplies drinking water to about 48,327 residents in New Kensington and surrounding Westmoreland County, Pennsylvania. Their water originates from the Allegheny River, a surface water source within the Ohio River basin. The MA-New Kensington treats this water at its conventional filtration plant on Barnes Street in New Kensington. Treatment processes include pre-oxidation with chlorine, followed by filtration and disinfection using chloramines or chlorine to ensure safe drinking water for the community. For inquiries, residents can contact the utility directly.

The Allegheny River watershed is geologically situated over sedimentary rock sequences dating back to the Pennsylvanian and Mississippian periods. These formations include notable layers like the Conemaugh and Allegheny Groups, along with the Loyalhanna Limestone. The presence of these carbonate-rich rocks means that as water flows through the watershed, it naturally picks up dissolved minerals such as calcium and magnesium. This continuous geological weathering process contributes to a moderately mineralized supply, shaping the water's overall chemistry and its tendency towards a harder profile.

This moderately hard water can lead to visible scale buildup on faucets, dishes, and glassware, diminishing their shine and requiring extra detergent for effective cleaning. Appliances that heat water, such as water heaters, dishwashers, and washing machines, are particularly susceptible to efficiency losses and premature wear due to mineral deposits. To combat these effects and prolong the lifespan of household equipment, homeowners often find regular descaling with vinegar beneficial. Installing a water softener is frequently recommended, especially for households that consistently notice soap scum or persistent spotting on surfaces.
