Fairfield County Water Quality
Fairfield County, Ohio stretches from the Columbus suburb of Pickerington in the northwest to the rural communities of Lancaster, Rushville, and Millersport in the south and east. The county has a stark divide in water quality: Pickerington and Lancaster city water runs 11–14 gpg (very hard), while rural Fairfield County well water — drawn from limestone aquifers — frequently tests 15–20 gpg, among the highest hardness readings in Ohio. Iron and sulfur contamination are common in rural well water. The county's rapid growth in the Pickerington corridor is bringing new construction with high-end appliances that are especially vulnerable to hard water damage.
