How much PFAS is in your drinking water?

Our PFAS drinking water test lets you have your tap water, drinking water from a well or bottled water professionally analysed. You receive the sample bottle at home, collect the sample according to the instructions and return it for laboratory analysis arranged through Normec Groen Agro Control.

Insight into very low PFAS concentrations

Results are reported directly in ng/L: nanograms per litre. The analysis covers an extended panel of PFAS components, including PFOA, PFNA, PFHxS and PFOS.

According to the supplied laboratory specifications, the reporting limit is 0.5 ng/L for most components and 0.2 ng/L for PFOS. Five components have a higher reporting limit of 5 ng/L. Your report states the results and corresponding reporting limits for each component.

What do you receive?

• PFAS-free sample bottle and shipping packaging
• Instructions for careful sample collection
• Return shipping label
• Professional laboratory analysis
• Digital laboratory report with results in ng/L
• Help understanding your results and reporting limits
• Support with questions

The usual analysis time is approximately 12 working days after the laboratory receives your sample.

What is included in your laboratory report?

• Results for each analysed component, with the corresponding reporting limits
• The sum of the four EFSA PFAS: PFOA, PFNA, PFHxS and PFOS
• The sum of the 20 PFAS in the PFAS-20 panel
• The sum of the measured PFAS

A result with a less-than sign, such as <0.5 ng/L, means the concentration is below the reporting limit. It does not automatically mean the substance is completely absent.

Open the multilingual PDF specification sheet (English: page 1)

This specification sheet was compiled by TestenopPFAS using information supplied by Normec Groen Agro Control on 14 October 2026. It contains the 53 components in the supplied table. It is not a laboratory analysis report and contains no measured sample results.

Want to check a water filter?

Have two separate water samples analysed: one before filtration and one after filtration, collected under comparable conditions. You can then compare the measured PFAS concentrations. Two analyses are required.

Frequently asked questions

How many components are analysed?
The new laboratory overview lists 53 components. See the full table in the PDF specification sheet; your final laboratory report states the components analysed in your sample.

Can you report below 1 ng/L?
The specified reporting limit is 0.5 ng/L for most components and 0.2 ng/L for PFOS. For five components it is 5 ng/L. There is no single limit for the entire panel.

Are PFOA equivalents calculated?
No. The laboratory does not calculate PFOA equivalents (PEQ). The unweighted sum of four PFAS is not a PEQ result and cannot be directly compared with a guidance value expressed in PFOA equivalents.

Is TFA included?
No. TFA, heavy metals, pesticides and bacteria are outside the scope of this test. A separate TFA water test is needed for TFA.

How do I collect the water sample?
Use only the supplied PFAS-free bottle and follow the instructions carefully. Fill it completely to the top and avoid contamination by touching the inside of the bottle or cap.

When will I receive the results?
Usually approximately 12 working days after the laboratory receives the sample, by email.
