Why Massachusetts changes the answer

This page earns its place only when the state context changes the testing path, evidence threshold, or the order of next steps.

Immediate orientation

What to do now

Do not assume a passing routine panel covers every bedrock risk that matters for drinking water

Verification path

What to test or compare next

Use certified labs and compare arsenic or radionuclide follow up only after the test scope is clear
