GET STARTED TESTING

‍We are certified by the state of Delaware, and we are approved by the EPA for UCMR5. Whether you have questions about UCMR5 program requirements, are looking for a quote or to begin the planning process, or are interested in sample collection, analysis, and reporting - we are here to help!

‍PFAS Analysis for Water Treatment: Many of our clients ask us how to purify their water by removing PFAS chemicals. With our water treatment team we identify and recommend NSF certified whole-house or point-of-use (under-sink) filtration systems that remove the specific PFAS chemicals in their water.

‍About EPA methods Method 537.1 and 533 for drinking water  

Both methods are acceptable for testing drinking water, but they vary in the number of PFAS which are detected. Both methods are performed using Solid Phase Extraction and Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS).

EPA Method 537.1 quatifies18 different PFAS, including the GenX chemical hexafluoropropylene oxide dimer acid (HFPO-DA).  

EPA Method 533 includes a total of 25 PFAS compounds, including fourteen of the eighteen listed in EPA 537.1 along with eleven additional PFAS: “short chain” perfluorinated acids, sulfonates, fluorotelomers, and poly/perfluorinated ether carboxylic acids. Many of these were not included in method 537.1. You can find the list of PFAS in EPA method 537.1 and 533 here.
