Fighting misinformation one water test at a time.
For years, the bottled water industry has painted tap water with one, broad, evil brush. But most drinking water is not bad at all. We exist to cut through the noise and bring you the facts.
We know this is complicated.
Where to begin? What should you test for? What does it all mean for your health and safety? Answers to all your big (and small) questions are always a chat away.
What test do I need?
When in doubt, we recommend that everyone start with one of our CORE KITS, which test multiple contaminants within a single test and are designed specifically for your drinking water source.
What’s the turnaround time?
Most people receive results within 3-5 business days after the lab receives their sample. However, some tests may require additional analytical time so be sure to check each kit’s product page for the most accurate estimate.
What does my report include?
Your report will rank your water against local and federal safety benchmarks, provide a thorough breakdown of any contaminants detected and how they may be affecting your health or plumbing, and provide non-biased treatment recommendations.
Are Tap Score labs certified?
Every lab facility in our network is certified with accreditations ranging from ISO to NELAC/ELAP, Direct State, DoD, DoE, DoH and beyond. Need a specific certification? Let us know so that we can meet your needs accordingly.
