Why test only a single substance?

Our Core Kits test for multiple contaminants with a single water sample and are custom designed for your specific drinking water source. If you only bought one test today, these would be it.

about specific

We could talk about analytes all day. So if you want to get into the scientific weeds with us or have questions about any of our specialized tests, we're here to help.


How effective are single tests?

Our specialized tests are highly focused, provide deep analysis of fewer contaminants, and designed for people with very specific needs. If you would like to analyze your water more broadly (and sometimes more cost effectively), we recommend our Core Kit collection.

What if I don't know what I need?

If you have specific reasons for testing but can't find what you're looking for, try our Customize Your Kit feature. After answering a few simple questions, we will curate some options for you.

What if my water source is unique?

We've never met a water sample we couldn't analyze. So whether your drinking water comes from rural sources, urban sources or anything in between, we can test it. Try our City Water, Well Water, Rain Water or Spring Water Core Kits for starters.

Can I take more than one sample?

Each testing kit is designed for a single sample at a single location in your home or on your property (i.e. kitchen sink). If you want to test your water at multiple locations, you will need multiple testing packages.
