About NH Well Water
This site exists because finding clear, reliable information about well water quality in New Hampshire is harder than it should be.
Nearly 500,000 New Hampshire residents rely on private wells for their drinking water. Unlike public water systems, private wells aren't monitored or regulated by any government agency. That means well owners are responsible for testing their own water and understanding the results — but the information to do that is scattered across government PDFs, academic papers, and water treatment company marketing pages.
We built NH Well Water to put the most important information in one place: what contaminants are common in your area, where to get tested, what your results mean, what your options are if something comes back high, and how to access NH's treatment rebate programs.
What This Site Is
- A starting point for understanding your well water
- Community-specific guides based on local geology, real water quality data, and government sources
- Links to certified testing labs, state programs, and local treatment companies
- Plain-language explanations of PFAS, arsenic, radon, and treatment options
- Rebate eligibility information — NH offers $5,000-$10,000 toward treatment systems
- A public information resource — not a sales funnel
What This Site Is Not
- A substitute for actual water testing (every well is different)
- Professional advice about your specific well or water system
- Affiliated with any government agency, water treatment company, or testing lab

Every well is different. Two wells on the same street can have completely different water quality. The only way to know what's in your water is to test it.
