Dunmore Water Hardness & Quality Report (2026)

Pennsylvania American Water draws its supply for the Abington District and surrounding areas from a network of surface reservoirs within the Lackawanna River watershed. Key sources include Lake Scranton, Williams Bridge, Elmhurst, Hollister, Curtis, and several Dunmore reservoirs: #1, #3, #4, #7, and Marshbrook. These waters are processed at treatment facilities operated by American Water, serving over 822,600 people. For water quality questions, residents can reach out to 570-343-3421.

The region's geology is characterized by Paleozoic sedimentary rocks, primarily from the Devonian period, including the Catskill Formation, which consists of red shales and sandstones. Adjacent areas also feature Silurian-age formations, such as limestone. Because the water is collected from surface reservoirs, it has limited contact with these mineral-rich bedrock layers. This geological setting results in a soft water supply with a low mineral content, a stark contrast to the harder water often found in areas relying on carbonate aquifers.

Homeowners in Dunmore will likely notice less scale buildup in their plumbing, water heaters, and appliances. This means less frequent maintenance for items like dishwashers and washing machines, and easier lathering of soap with less detergent needed. Spotting on glassware is also uncommon. While a water softener isn't typically necessary, regular filter changes and flushing with cold water are recommended if any discoloration from iron or sediment occurs. The Lake Scranton system's hardness averages between 1.2 and 2.7 grains per gallon, well within state and federal drinking water requirements.
