A public service of The Hunterdon Scoop · Hunterdon County, New Jersey
The best well and water contractors in Hunterdon County.
Most of this county drinks from private wells, a documented arsenic belt runs straight through it, and state law forces a water test at every home sale. The companies below are who you call when the pump dies or the test comes back wrong. Nobody paid to be here, and nobody can.
6 checked
- Samuel Stothoff Company (Flemington) — Founded 1886 — one of the oldest water companies in America, still family-run in Flemington. Cited by the Raritan Headwaters watershed nonprofit as a Hunterdon arsenic-treatment referral. The obvious anchor once the NJDEP pull clears.
- Stover's Wells & Pumps (Ringoes) — Fourth generation since 1949, Ringoes — which sits right in the county's documented arsenic belt they specialize in treating. Also on the Raritan Headwaters referral list. Strongest verified review volume in the category.
- Clinton Well and Pump (Glen Gardner) — The only company in the category that prints its license number plainly on its own site, and the reviews name the techs who show up fast on no-water emergencies. That's the 11pm-pump-failure call.
Why trust this page
We pull credentials from the official registries ourselves and print the date next to every status — well drillers and pump installers are licensed by NJDEP, a separate registry from the contractor board; we teach the lookup and our direct pulls are noted per company. Picks are editorial judgment on the checkable record: years in the trade, complaint patterns, review consistency, real presence in the county. No company paid to be listed, none can pay to become a pick, and when a pick has a weak spot we print it. Here are the full rules.
Every well and water contractor we checked
A genuinely strong local category anchored by multi-generation family firms, including one founded in 1886. The independent watershed nonprofit Raritan Headwaters maintains its own arsenic-treatment referral list, and the overlap with our picks-in-waiting is reassuring.| Company & services | Based in | NJDEP license | Registry status | BBB | Reviews (as reported) |

Registry status comes straight from the state's verification system on the date shown, and you can rerun any number there yourself in about two minutes. Review scores are what the named platforms report and we have not audited them. BBB grades as of July 2026. "Based in" is the registered address city, which sometimes differs from where a company says it operates. An active registration is the floor, not an endorsement; the picks we would actually call are above.
What it costs
Sourced ranges: well pump replacement $1,000 to $2,800 plus depth charges (2026 guides); drilling a new well $6,000 to $16,000 for a typical 200-foot well. Whole-house arsenic treatment adds a few thousand up front plus recurring media service.

Before you sign anything
- No water at all? Check the breaker and the pressure switch before you call anyone — five minutes that sometimes saves a service fee. Then call a pump specialist with 24-hour service, not a general plumber.
- Well companies in NJ carry NJDEP licenses (drilling and pump installation are licensed separately). Ask for the number.
- If a treatment system is proposed, ask for the lab result that justifies it, in writing. Treatment without a current test is a sales pitch.
- In the arsenic belt (Ringoes, Flemington, Kingwood, and south), price whole-house arsenic treatment with the recurring media-service cost included, not just the install.
- Selling or buying? The Private Well Testing Act panel is mandatory at closing. Coordinate the test early; a failed result mid-escrow is a fire drill.

Questions neighbors actually ask
Is arsenic in the water really a Hunterdon problem?
Yes, and it's geological, not pollution. A documented arsenic belt runs from the Princeton area up through Ringoes, Flemington, and Kingwood. New Jersey's arsenic limit (5 micrograms per liter) is twice as strict as the federal one, and plenty of county wells exceed it. Whole-house treatment works; it costs a few thousand dollars plus periodic media service.
Do I have to test my well when I sell my house?
Yes. New Jersey's Private Well Testing Act requires the full panel (which in Hunterdon includes arsenic, uranium, gross alpha, and more) at every sale or lease of a private-well property, and landlords must retest every five years. The sampling is done by certified labs; the companies on this page handle whatever the results turn up.
My well pump died. What does it cost to fix?
It depends on depth and whether it's the pump, the pressure tank, or the switch, so beware anyone quoting a number before diagnosing. What matters at 11pm is who answers and shows up; that's exactly what we weight in this category's picks.
One license checked every Thursday.
