Does a standard well water test include PFAS?

No. PFAS require a separate, specialized test. A standard panel for bacteria, nitrate, and metals will not detect them, so a clean standard panel cannot rule out PFAS.

How to Test Your Well Water for PFAS

PFAS are long-lasting chemicals linked to health concerns that can contaminate groundwater. Testing requires a specialized laboratory and careful sampling.

Quick Answer

PFAS (per- and polyfluoroalkyl substances) are man-made chemicals that persist in the environment and the body and have been linked to health concerns. They can reach private wells from industrial sites, firefighting foam, and landfills. Testing requires a specialized laboratory using the correct methods and sampling procedures.

Why PFAS are different

PFAS are sometimes called forever chemicals because they break down very slowly. They are not part of a standard well panel and are undetectable by sight, taste, or smell. Only a laboratory accredited for PFAS analysis, using the appropriate EPA drinking water methods, can measure them reliably.

Public vs. private regulation

The EPA has set drinking water regulations for certain PFAS in public water systems. Private wells are generally not federally regulated, so well owners must arrange their own PFAS testing. Check with your state for area-specific guidance and any known contamination sources.

How to test for PFAS

1Find a laboratory accredited for PFAS analysis in drinking water.
2Request their sampling kit and follow the instructions exactly, since many everyday materials contain PFAS and can contaminate a sample.
3Avoid wearing water-resistant clothing or using certain personal care products when sampling, per the lab’s guidance.
4Review the certified report, which lists individual PFAS compounds and concentrations.

If PFAS are found

Certified treatment options such as granular activated carbon, ion exchange, or reverse osmosis can reduce PFAS. Choose a system independently tested for PFAS reduction, and retest after installation.

Because PFAS sampling is easy to contaminate and the chemistry is specialized, this is one test where following the lab’s protocol precisely is essential for a trustworthy result.

Frequently asked questions

Does a standard well water test include PFAS?: No. PFAS require a separate, specialized test. A standard panel for bacteria, nitrate, and metals will not detect them, so a clean standard panel cannot rule out PFAS.
