Targeted Testing

Tests for every water type.

All homes, plumbing and drinking water sources are different, so we have spent years developing tests for every possible scenario, no matter where you live.

  • Get Covered

    Our Core Kits, based on your water source, will cover just about everything you need. We recommend everyone start here, then customize as needed.

SUPPORT

Are your labs EPA certified?

The EPA validates certain analytical methods but gives facility certification powers to outside agencies, which have certified ALL Tap Score labs with various accreditations ranging from ISO, to NELAC, to State, to DoD (among others).

How accurate are my results?

Instrumentation is extremely accurate when reporting concentration data and any variability in sample testing results comes from changes in the sample itself.

Which lab will my sample go to?

Depending on your location and the testing kit you select, your samples will be shipped to the laboratory that best meets your needs for turnaround time, instrumentation, and testing methods.

How complex is the report?

Your report, which includes your personalized tap score and contaminant breakdown, is designed to be comprehensive but simple, actionable and easy to read. And should you have questions, you know where to find us.
