Well water in Eaton, New Hampshire
No public well test results have been compiled for Eaton yet. The USGS national arsenic model estimates that 7% of the 0 people on private wells there draw water with arsenic above 5 ug/L, the EPA limit, based on geology, well depth and land use rather than local tests.
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.
32 test results across 11 contaminants from at least 5 wells, 1989 to 2022; manganese has the most at 5. Data refreshed September 3, 2026.
Compiled by Nick at Well Water Nerd from public records. How these pages are built
Data confidence: estimate. No state program or federal monitoring data for Eaton has been compiled here yet, so the arsenic figure is the USGS national model, not a measurement. Treat a high estimate as a reason to test, not as your well's number. Measured results are added as states publish them.

Among contaminants with a federal limit, no tested sample in Eaton came back above it. That is reassuring, but sampling is uneven: wells that were never tested are not in this data.
Manganese is widespread in local groundwater. It is mainly a staining and taste problem, but high manganese also carries a health advisory for infants.
The median radon reading (3,800 pCi/L) is above the 2,000 pCi/L level at which treatment is recommended. Radon in water raises indoor air radon when it is used for showers and laundry.

Wells in Eaton
99 domestic wells in Eaton are on record with the state since 1984. 96% are drilled into bedrock, and the typical well is 450 feet deep (one in ten goes past 810 feet).
In a typical Eaton well, bedrock starts about 31 feet down, the median yield is 10 gallons per minute, 12% 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.
- Open NHDES OneStop and choose Water Well.
- Enter your town and one word of your street name. Leave out the house number and the Road or Street part; a short search matches more.
- In the results, click Show for your address to see the report: total depth, depth to bedrock, casing, yield in gallons per minute, static water level, and the driller.
- Save Results exports the whole list to a spreadsheet.
Reports exist only for wells drilled since January 1984, when reporting became mandatory, and street names are as they were when the well was drilled.
The rock under Eaton
Not a principal aquifer
The USGS map places this area outside any principal aquifer, which usually means wells here draw from fractured bedrock or thin local deposits rather than a large regional aquifer. Bedrock wells of that kind are where arsenic, radon and uranium turn up, and yields vary from well to well.
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 Eaton
NHDES records 1 regulated sites in Eaton, among 1 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.
- 1
- registered underground storage tank siteRegistered tanks are regulated and inspected; they matter most when they are old or near a shallow well.

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.
