Easton Water Hardness & Quality Report (2026)

The Easton Area Water System serves Easton, Pennsylvania, and surrounding areas in Northampton County. Water is sourced from the Delaware River and treated at the Easton Water Treatment Plant using conventional methods including filtration and hypochlorite disinfection. The Easton Suburban Water Authority also operates in the region, publishing annual Consumer Confidence Reports detailing test results and quality maintenance. The utility can be reached at 610-258-7181 and 3700 Hartley Ave, Easton, PA.

The Delaware River watershed spans multiple states, with Easton's intake influenced by upstream tributaries including the Lehigh River. Underlying geology features folded and faulted Paleozoic formations from the Appalachian orogeny, including the Mahantango Formation and Onondaga Limestone alongside Silurian-Devonian carbonates and shales. These carbonate-rich bedrock layers release dissolved calcium and magnesium into the river through natural dissolution, imparting a moderately mineralised quality to the supply; no groundwater aquifer is involved as this is surface water.

Moderately hard water causes moderate scale buildup in water heaters, dishwashers, and washing machines, reducing efficiency and lifespan over time. Spotting on glassware and drier laundry are common household effects. Regular descaling of fixtures every one to two years and vinegar soaks help mitigate mineral deposits. A water softener is recommended for optimal performance, especially in homes with older plumbing. Water quality scores 80/100 with minor concerns, including two contaminants above health guidelines per independent testing; the system meets lead and copper compliance standards and treatment involves conventional filtration and disinfection.
