Eurofins Eaton Analytical's PFC Testing Capabilities

PFC Testing in Water

Eurofins Eaton Analytical was one of the first commercial laboratories nationwide to secure laboratory approval for EPA’s UCMR3 and was responsible for more than 40% of the national UCMR3 PFC data. Eurofins Eaton Analytical maintains dedicated instruments specifically for Method 537 at both the Monrovia and South Bend laboratories, and a customized small volume method in Monrovia optimized for short chain PFCs, and offers extensive experience in low-level reporting. As the largest potable water focused laboratory in the United States, we have worked with municipalities, multi-nationals, state governments, industry associations and the U.S. EPA.

What are PFCs?

Perfluorochemicals or Perfluorinated compounds (PFCs) are a large group of manufactured compounds that are widely used as surfactants in industrial applications. Many of these applications make everyday products more resistant to stains, grease and help to make them repel water. PFCs are also utilized in Aqueous Film Forming Foams (AFFF) that are used to fight fires and in fire training exercises. Due to their chemical resistence and biological persistence several PFCs, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in particular, have been named in the Stockholm Convention as Persistent Organic Pollutants (POPs). PFCs demonstrate unique chemical characteristics that are exhibited by their bioaccumulation in wildlife and their propensity to migrate to and from soil to water. There is widespread wildlife and human exposure to PFCs, predominantly PFOA and PFOS.
