Franklin County Water Quality
Franklin County, Ohio is the most populous county in the state and the heart of the Columbus metro area. The vast majority of Franklin County residents receive water from Columbus Water Works, which draws from the Scioto River and Hoover Reservoir. While this water meets all EPA standards, it consistently tests as "very hard" — between 9 and 13 grains per gallon — causing scale buildup on appliances, fixtures, and plumbing throughout the county. Chlorine disinfection adds taste and odor concerns, and PFAS "forever chemicals" have been detected in Central Ohio water systems. Outer Franklin County communities on well water face additional challenges including iron, sulfur, and bacterial contamination.
Columbus Water Works delivers water that consistently tests "very hard." Scale accumulates on water heaters, dishwashers, and fixtures across every Franklin County community.
Columbus Water Works uses chlorine disinfection. Trihalomethane (THM) byproducts form in the distribution system and contribute to taste and odor complaints.
Ohio EPA has flagged PFAS contamination in several Central Ohio water systems. Reverse osmosis is the gold-standard removal method for drinking water.
Studies show hard water reduces water heater efficiency by up to 48% and shortens appliance lifespan by 30–50% — a significant cost for Franklin County homeowners.
