Huntington Water Hardness & Quality Report (2026)

The Huntington Water System, managed by American Water in West Virginia, provides water to Huntington and nearby areas in Cabell County. Its main source is the Ohio River, with water pulled through a 36-inch intake to the Huntington Water Treatment Plant. This plant delivers about 10.46 million gallons daily. The supply comes primarily from surface water (98%), with a small percentage from groundwater (2%) and purchased water (1%). Treatment processes include coagulation, flocculation, sedimentation, filtration, disinfection, and the addition of an inhibitor to manage water quality. The Ohio River watershed feeding Huntington is in the unglaciated Appalachian region, with the Guyandotte River as one of its tributaries.

The region's geology is marked by Mississippian limestones, specifically the Greenbrier Formation, and Pennsylvanian Pottsville Group sandstones. These rocks dissolve over time, contributing dissolved calcium and magnesium to the water, giving it a moderately mineralized character. This natural hardness stems from the carbonate-rich layers prevalent in the Appalachian Basin. Unlike water from softer, glacial-influenced areas, this supply carries a noticeable mineral content due to the extensive drainage across these sedimentary formations.

This moderately hard water can lead to scale buildup in appliances like water heaters, dishwashers, and washing machines, potentially shortening their lifespan and increasing energy consumption. You might also notice reduced soap lathering, requiring more detergent, and spotty dishes after washing. To combat scale, regularly clean fixtures with vinegar and flush your water heater every six months. Installing a scale-inhibiting showerhead can also help. For persistent issues, a water softener is often recommended to protect your plumbing and improve appliance efficiency. The system's hardness typically falls between 61-150 ppm, and treatment ensures compliance with EPA standards.
