Where private wells (and usually septic systems) are most common
Ohio ranks 6 of 45 states and territories by people on private wells (USGS 2015). In 16 of its 88 counties more than half of residents drink from a private well; homes there usually also treat wastewater on site, so a septic check and a well test tend to come up together at sale. The highest shares:
- Morrow County: 80% of 35,074 residents on a private well
- Geauga County: 76% of 94,102 residents on a private well
- Holmes County: 74% of 43,909 residents on a private well
- Carroll County: 72% of 27,811 residents on a private well
- Vinton County: 71% of 13,048 residents on a private well
- Hocking County: 68% of 28,491 residents on a private well
- Morgan County: 65% of 14,777 residents on a private well
- Paulding County: 62% of 18,976 residents on a private well
