Water in Whitehall
The 2020 census counted 20,127 people in Whitehall, in Franklin County. It is about 6.5 miles from downtown Columbus.
Whitehall is supplied by Columbus Water & Power as a contract community. Columbus treats Scioto River and Big Walnut Creek surface water, and Scioto Valley groundwater at the Parsons Avenue plant. The 2025 report lists finished-water hardness of 5.7–7.3 grains per gallon by plant (98–125 mg/L) and a system summary of 115 mg/L. The city does not publish which plant feeds a single Whitehall address, so that range is the number we use, and we still test at the house. Columbus Water & Power says a home filter is not required to make the water safe to drink. On this supply, a softener or filter is a choice about taste, odor, scale, and how appliances wear, not a safety fix.
City of Columbus water (Columbus Water & Power) - listed contract community publishes a hardness figure for this supply: 5.7-7.3 gpg (98-125 mg/L) 2025 annual avg by plant; system avg 115 mg/L.

Reverse osmosis installation here
Reverse osmosis in Whitehall belongs at the kitchen sink, for cooking and drinking. It is not a whole-house softener. A unit should be certified for the reductions you actually want. On Columbus water, the 2025 report shows higher sodium and sulfate at the Parsons Avenue plant and higher nitrate at Dublin Road, before the city's nitrate removal process. Those are drinking-water details, and the city does not pin them to one Whitehall street.
