Certified & Compliance Testing

We offer a full range of tests to clients across North America.

We are proud to offer a full range of DIY, Informational and Certified Testing options to Tap Score clients across North America. We take quality control and transparency very seriously. Tap Score customers have the option to choose between various Certification Levels among Water Testing Packages. Most residential and small business clients do not need to submit results to the State for compliance purposes and can indeed save money through Tap Score’s DIY and Informational Lab Testing Offerings. (Such testing packages cost 2 -5x less than a State’s certified equivalent but may have lower accuracy on certain parameters due to customer-sampling or longer delivery times to the lab.) For more details on this trade-off, please read our informational versus compliance testing overview.

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.

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.
