- Bellefontaine is nicknamed 'The Peak of Ohio' because Campbell Hill, the highest point in the state, lies inside the city limits — yet Ohio EPA's susceptibility analysis for the city's wellfield blames the flat…

- The city's drinking water comes from a carbonate aquifer whose water table sits less than 30 feet below the surface in most places — shallow enough that Ohio EPA counts the depth itself as a susceptibility factor.
- Volatile organic compounds turned up in Bellefontaine's raw and treated water between 1990 and 1998; none have been detected since the new plant opened in 1998, which still runs a treatment step dedicated to keeping…
- Honda is Bellefontaine's largest modern employer, with area manufacturing at Marysville, East Liberty and Troy.

Treatment & pressure
How it is treated
Municipal wells in the city's West wellfield draw from a shallow carbonate bedrock aquifer (depth to water usually less than 30 feet), west of Lewis Ratleff Park. Water is treated at the plant placed in service in 1998, which includes a treatment system operated specifically to keep volatile…

Supply stress
Ohio EPA's source water assessment rates the aquifer supplying Bellefontaine's West wellfield as HIGHLY susceptible to contamination, for four stated reasons: water quality results indicate impacts of volatile organic compounds; the carbonate aquifer has a shallow depth to water, in most areas less than 30 feet below ground; the…
