Wilkes-Barre Water Hardness & Quality Report (2026)

The Wilkes-Barre Area Water Supply Authority serves Luzerne County, Pennsylvania, primarily the city of Wilkes-Barre and surrounding communities. Water is sourced from the Susquehanna River at the USGS-monitored site 01536500 near Wilkes-Barre, with intake in the North Branch. Treatment occurs at the authority's facility, serving a population of around 50,000 through distribution across the Greater Wilkes-Barre area. Treatment involves coagulation, filtration, disinfection with chlorine, and fluoridation, with robust monitoring for sediments and organics given the river source. Utilities like American Water also serve Wyoming Valley communities under the same EPA standards.

The Susquehanna River watershed spans the Appalachian Plateau, flowing through Pennsylvania's Valley and Ridge Province with headwaters in New York. Paleozoic bedrock is dominated by Devonian Catskill and Pocono Formations—shales, sandstones, and siltstones—alongside key units like the Marcellus Shale and Hamilton Group sandstones. Lacking extensive karst or limestone aquifers like those in central Pennsylvania, this siliceous geology yields moderately mineralised, soft water with low dissolved calcium and magnesium content. Pleistocene glacial till and alluvial deposits further contribute to the river's flow.

Soft water minimizes scale buildup in pipes, heaters, and appliances, reducing maintenance needs and extending the lifespan of water heaters, dishwashers, and laundry machines. Soap lathers easily without leaving excess residue on fixtures. No water softener is needed; instead, monitor for corrosion risks common in soft supplies and use phosphate inhibitors if required. No specific PFAS or lead exceedances have been noted in recent data, with pH typically 7–8 and copper compliance assured through corrosion control.
