PFAS Analysis
Our environmental laboratory offers PFAS analysis by modified methods ASTM D7968 for soil and EPA 537 for groundwater. Both soil and groundwater PFAS analyses are determined by state-of-the-art liquid chromatography triple quadrupole mass spectrometer technology that can detect ultratrace contamination in parts-per-trillion.

ADDITIONAL INFORMATION
PFAS are contaminants of emerging concern often requiring monitoring and remediation of soil and water. Currently, EPA 537 by liquid chromatography triple quadrupole mass spectrometer (LC/MS/MS) is the only approved method for determining PFAS in drinking water. Other methods have been developed to meet the growing public pressure for the remediation of PFAS in soil and groundwater. Modified methods like EPA 537 (M) and ASTM D7968 (M) are widely accepted by agencies such as the Department of Defense (DoD), state level pollution control agencies, and public health departments to effectively assess PFAS contamination and remediation.
LEGEND’s methods include EPA 537 (M) and ASTM D7968 (M) by LC/MS/MS to positively identify these compounds at low level detection limits; preventing both false negatives and false positives. Our promise is to offer legally defensible data that is accurate and true. This assures that samples analyzed by our laboratory can be used for regulatory and monitoring purposes.
Naming for this class of chemicals:
- Perfluoroalkyl Substances (PFAS)
- Perfluorinated Compounds (PFCS)
- Perfluorinated Alkylated Acids (PFAAS)
Including Perfluorooctanoic Acids (PFOA) and Perfluorooctanesulfonic Acids (PFOS) which have been voluntarily phased out by U.S. manufactures.
GenX is a trade name for a group of replacement chemicals with similar chemical structures/properties to PFOAs and is also a persistent contaminant suspected to be toxic in the environment.
To learn more about per- and polyfluoroalkyl substances (PFAS), visit the EPA website.
Exposure to PFAS has the potential to accumulate in the body by ingesting PFAS contaminated water and food. Federal and state funded studies have proven that PFAS can cause adverse health effects at a wide range of exposure limits. At high concentrations, PFOA and PFOS can cause birth defects, cancer, and comprise liver, kidney, and thyroid function. Health advisory warnings for PFAS have been issued to protect drinking water and human health.
