Mountain Top Water Hardness & Quality Report (2026)

PA American Water - Nesbitt Division supplies Mountain Top, Pennsylvania, with drinking water drawn from both Nescopeck Creek and local groundwater wells. This mixed water source is processed at the Nesbitt Water Treatment Plant before reaching the taps of several thousand residents in Luzerne County. The Nescopeck Creek watershed, nestled within the larger Susquehanna River Basin, flows through rolling Appalachian foothills. The utility's treatment process includes coagulation, filtration, disinfection via chlorination, and corrosion control, ensuring the water meets federal and state drinking water standards, although some contaminants have been detected above health advisories.

The region's geology is dominated by Devonian-age shale, siltstone, and sandstone formations belonging to the Catskill and Pocono Groups. As water percolates through the fractured bedrock, it dissolves calcium and magnesium ions. Groundwater sources tap into aquifers like the Glenshaw and Casselman Formations, which contain limestone interbeds and karst features. These geological elements can enhance mineral leaching, contributing to a moderately mineralized supply. While the surface water from Nescopeck Creek tends to be softer, the groundwater picks up more dissolved solids, resulting in a balanced, yet mineral-rich, water profile.

With its moderately hard water, you might notice some scale buildup over time in appliances like dishwashers, washing machines, and water heaters, which can reduce their efficiency. Faucet aerators and showerheads can also accumulate deposits, potentially affecting water flow. Simple maintenance, such as monthly descaling with vinegar and annual appliance checks, can help manage these issues. If you experience persistent spotting on glassware, dry skin, or stiffness in laundry, a water softener could be beneficial, though it's not a necessity for every household. While the water meets EPA legal limits, two contaminants were recently reported above health-based guidelines, prompting advice for using certified filters for added protection.
