About WellWater HQ: Free Well Water Testing Guides

WellWater HQ is an independent site. WellWater HQ publishes free private well water guides and testing tools, grounded in EPA and state health department standards.

What this site is

Private wells aren't covered by the Safe Drinking Water Act, so testing is entirely on the homeowner, and most people don't know what to test for or how often. We cover the basics: coliform bacteria, nitrates, arsenic, and the regional contaminants that show up in state well surveys, along with what a lab report actually means once you have it.

How we work

Our testing recommendations come from EPA private well guidance and state health department well programs, cross-referenced where state advice differs from federal minimums. Guides are written with AI assistance and checked against those sources before publishing, and our editorial policy lays out how. When a contaminant threshold has both an EPA guideline and a stricter state limit, we show both.

How we make money

Everything on this site is free to read. We earn affiliate commissions when readers buy water test kits or treatment systems through links here, disclosed in full here.

Corrections

Contaminant limits and testing intervals vary by state and get revised. Report an error via contact and we'll correct and date it.
