NLS – Your PFOA / PFOS Experts

 

Perfluorooctanioc acid (PFOA) and perfluorooctane sulfonate (PFOS) are two compounds from a group broadly known as perfluorocarbons.  These chemicals were used extensively in the production of stain-resistant and non-stick products along with fire-fighting foam.  Since the early 2000s, they have been subject to regulatory review and production restrictions have been imposed.  Recently, these compounds have been discovered as significant environmental contaminants in a number of sites across the nation.  Various states have set advisory limits for these compounds. EPA has established a non-enforceable Health Advisory Level of 70 ppt (ng/L) for PFOA and PFOS both individually and combined.

Northern Lake Service developed method 537 to test for these perfluorinated compounds in response to UCMR3 – the third round of EPA’s national program to collect occurrence data of unregulated contaminants in our nation’s public drinking water sources.   Working for individual water systems and directly for EPA as one of only four small-system contract labs, NLS analyzed thousands of samples from 2013 to 2015.

 

We continue to perform testing for a number of investigative and remediation projects around the state and country.  Call today for more information about testing for perfluorinated compounds
