PFAS – PFOA, PFOS, PFNA and More in Drinking Water

Water Testing Lab DelawareDrinking Water PFAS Testing

We have obtained accreditation for performing analysis of 18 PFAS compounds in drinking water by EPA 537.1 for samples in Pennsylvania, Maryland, and Delaware.  We are the only privately-owned, independent, single site laboratory in Pennsylvania with this testing capability.  Your analysis will be performed at our laboratory in Reading, PA- no shipping samples to a far away location.   You can have peace of mind knowing your samples will be handled locally by trusted professionals.

Testing for PFAS in Drinking Water


EPA 537.1 requires a solid phase extraction (SPE) on the sample, followed by analysis using Liquid Chromatography with tandem Mass Spectrometry (LC-MS-MS).

The sample container is a 250 mL polypropylene (plastic) preserved with trizma as a pH buffer.  Field Reagent Blanks should be collected when testing for compliance purposes.
