Well water in York township, Ohio

In York township, none of 31 tested well samples exceeded the EPA limit for fluoride, based on public data from USGS Water Quality Portal.

The strongest signal is coliform bacteria: Recommended for every private well, every year, too few samples to carry the headline but first on the test list below.

246 test results across 9 contaminants from at least 8 wells, 1983 to 2014; chloride has the most at 33. Data refreshed September 3, 2026.

What this means

Among contaminants with a federal limit, no tested sample in York township came back above it. That is reassuring, but sampling is uneven: wells that were never tested are not in this data.

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 York township

107 domestic wells in York township are on record with the state since 1970. 81% are drilled into bedrock, and the typical well is 64 feet deep (one in ten goes past 132 feet).

In a typical York township well, bedrock starts about 18 feet down, the median yield is 4 gallons per minute, 38% of wells yield under 3 gallons per minute and usually need a storage tank.

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.

  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 York township

Pennsylvanian aquifers

Sandstone. Sandstone wells draw from pore space in the rock and tend to be dependable. Iron, manganese and hardness are common, and some sandstones carry arsenic or radium, so a first test should include both.

Contamination sources on record in York township

Ohio EPA records 29 leaking underground storage tank sites and 1 hazardous waste site in York township, among 34 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.

leaking underground storage tank sitesGasoline and heating oil that leaked from tanks move through groundwater as benzene, MTBE and other volatile organic compounds.
