Water Filtration Delaware, Ohio — Pure Aqua Columbus
Delaware County has some of the hardest water in Central Ohio — 160–200 mg/L hardness and 3–10 ppm iron in well water. City water from the Olentangy River carries agricultural nitrates and herbicides. Pure Aqua Columbus solves it all with Westinghouse-authorized systems.
What's in Delaware's Water?
Delaware is one of Ohio's fastest-growing counties — but rapid growth doesn't mean better water. Whether you're on city water from the Olentangy River or a private well, Delaware County has some of the most challenging water quality in all of Central Ohio.
Delaware County well water frequently tests at 3–10 ppm iron — among the highest in Central Ohio. Even 0.3 ppm causes staining; levels this high mean orange water, rust-stained laundry, and damaged appliances.
Delaware County groundwater hardness of 160–200 mg/L is among the hardest in all of Central Ohio. Scale buildup destroys water heaters, clogs pipes, and leaves white deposits on every surface.
Delaware city water comes from the Olentangy River, which is impacted by agricultural runoff. Nitrates and herbicides from surrounding farmland are a documented concern — especially for infants and pregnant women.
Atrazine and other herbicides used on Delaware County farmland have been detected in the Olentangy River watershed. Reverse osmosis is the most effective removal method available.
Properties outside Delaware city limits rely heavily on private wells with no municipal treatment. Annual testing and whole-house filtration are essential for these homeowners.
We're based in Central Ohio and typically schedule Delaware installations within 3–5 business days of your free water test.
