EPA Method 537.1 PFAS Drinking Water Testing Laboratories
EPA Method 537.1 is a US EPA drinking water method for determining selected per- and polyfluoroalkyl substances by solid phase extraction and liquid chromatography with tandem mass spectrometry.
When is it used?
- Finished drinking water monitoring where this method is specified
- Public water system sampling programmes and consumer confidence reporting support
- Private well testing where a drinking water method is appropriate
Sample considerations
- It is a drinking water method — non-potable matrices such as wastewater and leachate are addressed by other methods.
- Use the laboratory's containers, preservative and sampling instructions; substitutions can invalidate the batch.
- Analyte lists differ between the drinking water methods, so confirm which compounds you need reported.
