What individual samples found

Each row summarizes every public sample for that contaminant inside Concord 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.

What this means

The contaminants most often above their limit here are arsenic (2% of 52 samples) and lead (2% of 56 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.

Chloride, Manganese, and Iron 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 Concord township

616 domestic wells in Concord township are on record with the state since 1970. 34% are drilled into bedrock, and the typical well is 73 feet deep (one in ten goes past 137 feet).

In a typical Concord township well, bedrock starts about 35 feet down, the median yield is 15 gallons per minute, 2% of wells yield under 3 gallons per minute and usually need a storage tank.

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.

  1. Open ODNR water well log search and choose Water Well.
  2. 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 Concord 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.

Official help in Ohio

Two places to start that are not selling anything: the state program that answers private well questions, and its list of labs certified to run drinking water tests. A certified lab is the difference between a result you can act on and a number.

Contamination sources on record in Concord township

Ohio EPA records 124 leaking underground storage tank sites and 13 hazardous waste sites in Concord township, among 145 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.

124
leaking underground storage tank sitesGasoline and heating oil that leaked from tanks move through groundwater as benzene, MTBE and other volatile organic compounds.
13
hazardous waste sitesSolvents, degreasers and metals from industrial sites can travel far in fractured bedrock.

Systems we would look at first

Some links below are affiliate links. If you buy through one, the merchant pays us a commission at no extra cost to you. It does not change which products we list or what the data says.

For arsenic

Under-sink reverse osmosis system

under-sink or countertop, about $300

Look for NSF/ANSI 58 certification listing the contaminant you need removed.

For arsenic

Whole-house arsenic and uranium filter

whole-house, at the point of entry, about $2,500

Adsorptive iron-based media; sized to your well yield.

For arsenic

Aquasana SmartFlow reverse osmosis

under-sink or countertop, about $225
