You cannot see lead, bacteria, nitrates or PFAS in water, and you cannot taste most of them either. Testing is the only way to know what is coming out of your tap, and it tells you whether you need a filter and which kind. The best home water test kit covers the contaminants that matter for your water source, gives results you can trust, and explains what they mean.
We compared the most popular lab tests and at-home kits on contaminants covered, accuracy, ease of use, turnaround time and cost. Here are our picks for 2026.

How to choose a water test
1. Start with your water source
City water customers should read their utility’s yearly water quality report first. Private well owners are responsible for their own testing.
2. Pick lab or at-home
Certified lab tests give accurate numbers for health decisions. At-home kits and strips are good for quick screens and routine checks.
3. Match the test to your concerns
Older homes may need lead testing. Wells need bacteria and nitrate tests. Homes near industrial sites or military bases may want PFAS testing.
4. Follow sampling instructions
Results depend on how you collect the sample, such as first-draw water for lead. Read the instructions before you start.
5. Act on the results
Use your results to choose a filter certified for the contaminants you found, and retest after installing it.
Testing well water
The EPA recommends that private well owners test their water regularly, because no utility does it for them:
- Test every year for total coliform bacteria, nitrates, total dissolved solids and pH.
- Test after flooding, if the water changes taste, smell or color, or if anyone gets sick.
- Test for lead, arsenic, radon and other local concerns based on your area’s geology.
- Use a state-certified lab; your local health department can recommend one.
Frequently asked questions
Are home water test strips accurate?
They are good for rough checks of hardness, chlorine and pH, but not precise enough for health decisions about lead or bacteria. Use a lab for those.
How do I test my water for lead?
Collect first-draw water that has sat in the pipes for at least six hours, and send it to a certified lab. Some utilities offer free lead testing.
How often should I test my water?
Well water every year at minimum. City water when you move in, if you have older pipes, or if anything changes.
Can I test for PFAS at home?
Reliable PFAS testing requires a specialized lab. Mail-in services like Tap Score offer PFAS panels.
Does my water utility test my water?
Yes, for the public system, and it publishes results in a yearly report. It does not test water inside your home’s pipes.
What should I do if my water has lead?
Use a filter certified to NSF/ANSI 53 or 58 for lead, run cold water before drinking, use only cold water for cooking, and contact your utility about service line replacement.
The bottom line
For most homes, Tap Score Essential City is the best home water test, with certified lab results and a clear report. Choose the Safe Home Ultimate kit for broad well testing, the Safe Home 14-in-1 DIY kit for a quick at-home screen, or the Varify Complete kit for routine checks.
