Test Kits & Labs

Well water testing costs vary by lab and test. See published 2026 prices from Penn State’s lab, Wisconsin’s state lab and Tap Score, plus the extra costs to plan for.

Well water test kits compared on what they measure, whether a lab runs the analysis, and when to use each, based on published specs. Plus the free option many people miss.

Should you use Tap Score, a local state-certified lab, or DIY strips for your well? A spec-based comparison of cost, coverage, bacteria handling and when each makes sense.
