What individual samples found
Each row summarizes every public sample for that contaminant inside Claibourne township. Above limit means above the EPA maximum contaminant level; where EPA has no enforceable limit, the row shows a health guideline or nuisance level instead.

| Arsenic 1985 to 2014 | 33 | 27% | 0 | 5 | 10 ug/L EPA limit | |
| Lead 1985 to 2014 | 32 | 6% | 0 | 1 | 15 ug/L EPA limit | |

Check my addressWhat this means
The contaminants most often above their limit here are nitrate (2% of 55 samples). A well next door can differ sharply from yours because bedrock fractures, well depth and plumbing all matter, so these rates describe the area, not your tap.
Manganese, Iron, and Chloride are widespread in local groundwater. They are mainly a staining and taste problem, but high manganese also carries a health advisory for infants.

Wells in Claibourne township
293 domestic wells in Claibourne township are on record with the state since 1970. 99% are drilled into bedrock, and the typical well is 57 feet deep (one in ten goes past 100 feet).
In a typical Claibourne township well, bedrock starts about 28 feet down, the median yield is 15 gallons per minute.
Bedrock wells are where arsenic, uranium and radon come from: the water sits in fractures in granite and metamorphic rock and picks up whatever the rock carries. That is why testing for those three matters more here than in a dug or gravel well.
Find your own well's report
The state keeps the driller's report for most wells drilled since 1984. It tells you how deep your well is, where bedrock starts, and how much water it makes, which decides what treatment can work.
- Open ODNR water well log search and choose Water Well.
- The log lists depth, depth to bedrock, casing, static water level, the pump test and the driller.
Ohio has required well logs since 1948, so most drilled wells have one.
The rock under Claibourne township
Silurian-Devonian aquifers
Carbonate-rock. Limestone and dolomite move water through cracks and solution channels, sometimes very fast. Bacteria and nitrate can travel from the surface to a well in days, so annual bacteria testing matters more here than most places; hardness is a given.
Classification from the USGS Principal Aquifers of the United States (national map, 2003 edition, GIS release 2015), read at the town centroid. A single well can sit in a different unit, especially near a boundary.

Contamination sources on record in Claibourne township
Ohio EPA records 10 leaking underground storage tank sites and 1 hazardous waste site in Claibourne township, among 12 regulated sites in total. Groundwater does not follow property lines, so a well within a few hundred feet of one of these is worth testing for what that site could release.
- 10
- leaking underground storage tank sitesGasoline and heating oil that leaked from tanks move through groundwater as benzene, MTBE and other volatile organic compounds.
- 1
- hazardous waste siteSolvents, degreasers and metals from industrial sites can travel far in fractured bedrock.
- 1
- lined landfill or transfer facility

Non-detects count as samples and are treated as zero when computing medians. Exactly at the limit counts as not above it. A sample belongs to the town containing the well's reported coordinates.
