PFAS cannot be identified by taste, smell, or color, so a certified lab test is the only reliable way to know whether they are in your water. EPA recommends using a state-certified laboratory and EPA-developed methods, especially if you rely on a private well or live near airports, military sites, fire-training areas, industrial facilities, or landfill leachate sources.
Key Takeaways
- Ask the lab which method it uses. EPA-developed drinking-water methods such as Method 533 or 537.1 are the common starting point for residential PFAS testing.
- If you use a private well, start with your state environmental or health department. EPA notes that private wells are not regulated under the Safe Drinking Water Act, so the owner has to initiate testing.
- PFAS testing is usually more expensive than a standard well panel. Typical homeowner pricing is often in the roughly $250 to $500 per sample range, sometimes higher when a large analyte list is requested.
- Use clean sample bottles and follow the lab instructions exactly. Everyday items like waterproof clothing, cosmetics, and some food packaging can contaminate the sample if you are careless.
- Retest after treatment is installed and then on a maintenance schedule. PFAS filters only work when cartridges or media are replaced before breakthrough occurs.
Practical Testing Plan
- Check your local utility report if you are on city water, or contact your health department if you are on a well.
- Order a state-certified lab kit that lists PFAS methods and the compounds included.
- If PFAS are detected, compare the results with current EPA drinking-water standards and then size treatment around the actual concentration and the PFAS species reported.
