Perfluoroalkylated Substances (PFAS)
Perfluoroalkylated Substances (PFAS) are a group of man-made organofluorine chemical compounds that were used to provide protective coatings for products like carpet and fabric, food-use packaging, and in some fire deterrent foams. In 2009, PFAS were listed under the Stockholm Convention as persistent organic pollutants due to their longevity in the environment, bioaccumulative nature, and toxicity. This screening looks for 3 perfluoroalkylated substances; results are reported in parts per trillion (ppt) which is equivalent to nanograms of contaminant per liter of water (ng/L) for each.
Perfluorooctanesulfonic acid (PFOS)
Perfluorooctanoic acid (PFOA)
Perfluorobutane sulfonate (PFBS)
The primary exposure route for PFAS is ingestion through food and drink as well as water. PFAS are persistent organic pollutants, meaning they last a long time and bioaccumulate (i.e., PFAS remain in the body for several years). Toxicological studies indicate that high concentrations can cause an array of reproductive and developmental effects, immune system effects, and liver and kidney damage in animals. Some of these effects have been detected in humans but there is insufficient data to determine the extent of those effects.
This is a screening, your sample will go through a simplified version of the typical rigorous quality control process. This screen is intended to give you an idea of the PFAS levels in your water; if your results indicate a level near or above the US EPA Health Advisory Level you should contact your local health department and/or consider additional testing using an accredited method. This screen is intended for personal information purposes only and is not intended for legal regulatory compliance matters.
