SafeHome Ultimate Well Water Test Kit

Well Water Testing · $150–$600 for a professional service

Check price →

A broad DIY strip-and-vial panel that screens for bacteria, nitrates, lead, pH, hardness, and more — a sensible annual habit for the ~43 million homes on private wells. It is a strong screening tool, but for anything official (a real-estate closing, a mortgage requirement, or a positive bacteria result) you still need an EPA/state-certified or NELAP-accredited lab with proper chain of custody. Use this kit to catch problems early, then confirm with a certified lab.

When a kit isn’t enough: a DIY kit is a screening tool. For well water testing, confirm any concerning result with a EPA-Certified Labs-aligned professional or certified lab before acting.
