We know this stuff feels complicated, but we are dedicated to keeping it simple. Answers to all your questions are always a chat or FAQ away.
Which test is right for me?
When in doubt, start with a Core Kit to analyze multiple contaminants with a single test. If you have more specific motivations for testing, try our Customize My Kit feature to match your needs to the right test(s).
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 will 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.
