Testing for PFAS in Non-Potable Water

How Can We Help?

DoD ELAP Accredited PFAS Testing

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals found in thousands of consumer and industrial products to help make them resistant to heat, stains, grease and water.  Common uses include:

  • Non-stick cookware
  • Stain and water-resistant textile coatings
  • Food packaging coatings
  • Metal plating and semiconductors
  • Aqueous Film Forming Foam (AFFF)

These chemicals are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects. [source: epa.gov]

We perform testing on non-potable water (ground, surface, storm water) using LC/MS-MS technologies in support of trace level reporting of these emerging contaminants.  Microbac is DoD ELAP accredited according to DoD QSM version 5.1 Table B-15 performing Method 537 with modifications.
