Well water in Springfield, New Hampshire

In Springfield, 16% of 44 private wells tested between 2006 and 2020 had lead above the New Hampshire guidance level (15 ug/L), according to NH DHHS.

62 private wells tested 2006 to 2020 in state summaries; 4 individual samples from 4 wells, 1986 to 1989. Data refreshed September 3, 2026.

What this means

Among homeowners in Springfield who sent a sample to the state lab, the health-based limits most often exceeded were lead (16% of 44 wells), uranium (16% of 51 wells), and copper (9% of 44 wells). These are ordinary wells tested by their owners, so the shares are the best available picture of a typical well here, with one caveat: people test more often when they suspect a problem.

Radon was above the New Hampshire guidance level of 2,000 pCi/L in 68% of 25 wells. Radon in water matters because it moves into indoor air during showers and laundry.

Sodium and iron exceed the state's advisory level in a sizable share of wells; these are mostly a taste, staining or diet issue rather than a toxicity one.

Wells in Springfield

157 domestic wells in Springfield are on record with the state since 1984. 98% are drilled into bedrock, and the typical well is 425 feet deep (one in ten goes past 605 feet).

In a typical Springfield well, bedrock starts about 20 feet down, the median yield is 5 gallons per minute, 32% 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.

Contamination sources on record in Springfield

NHDES records 2 reported spills and releases in Springfield, among 19 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.

2: reported spills and releasesMost spills are fuel; a few are solvents or chemicals that reach the water table.
6: registered underground storage tank sitesRegistered tanks are regulated and inspected; they matter most when they are old or near a shallow well.
11: other remediation projects

Treatment that fits the local profile
