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.

11–20 gpg
Extreme Hardness Range

Fairfield County spans from very hard city water (11–14 gpg) to extreme well water hardness (15–20 gpg) in rural areas. This is among the highest hardness in Central Ohio.

Iron
Rural Well Water

Rural Fairfield County well water frequently contains iron at 2–8 ppm, causing severe orange staining on fixtures, laundry, and appliances.

Sulfur
Odor Issues

Hydrogen sulfide is common in Fairfield County well water, producing a rotten egg smell that affects drinking, cooking, and bathing.

New Construction
Pickerington Growth

Rapid new construction in the Pickerington corridor brings high-end appliances — tankless heaters, smart dishwashers — that are especially vulnerable to hard water damage.
