WellTestList refuses to turn well testing into a sales call

Field notes

The homepage uses a three-part comparison: county environmental-health programs, certified drop-off laboratories, and independent mail-in kits. It records practical differences such as whether a PDF is normally supplied, whether a lab may serve utilities only, and whether a lender might require a named local laboratory or chain-of-custody form. Four state pages are linked—Michigan, Minnesota, Pennsylvania, and Texas—while the site says its coverage will expand one state or lab page at a time.
