The map includes a wealth of demographic data about the populations living near wells fracked with PFAS and/or PFAS precursors. PFAS: The Forever Chemicals. And as the nickname suggests, "forever chemicals" are here for a long time. PFAS. PFAS (Per- and polyfluorinated alkyl substances), also known as the Forever Chemicals, are a large chemical family of over 9,000 highly persistent PFAS chemicals are often called forever chemicals because they do not easily degrade in the environment or in the body, so they accumulate in both over time. PFAS chemicals, particularly those with long chains of carbon such as PFOA and PFOS, have been linked to immune, thyroid, kidney, and reproductive problems. Known as Forever Chemicals, PFAS (Per- and poly-fluoroalkyl substances) chemicals are a family of synthetic chemicals that build up in humans and are linked to numerous health problems including cancer. In a recent analysis, the Environmental Working Group estimated that the common practice of spreading sewage sludge for fertilizer could have contaminated up to 20 million acres of U.S. croplands with the forever chemicals. Small concentrations of PFAS have been found in human bloodstreams.

Giant chemical companies who have produced per- and polyfluoroalkyl substances (PFAS) - known as forever chemicals due to their persistence in bodies and the environment - have set aside $4 billion dollars to pay for their expected liability for cleaning up that historic contamination. To help address this toxic threat, we reviewed the definition of hazardous substance in our environmental cleanup law and concluded that PFAS compounds meet the definition. One of the main concerns about PFAS is how long they last. Image credit: Shutterstock/Dmitry Naumov. PFOA (Perfluorooctanoic Acid) and PFOS (Perfluorooctanesulfonic acid) are the most common of the PFAS family, although both are being phased out due to their adverse health and environmental effects. Both blood and plasma donation resulted in significantly lower PFAS chemicals than the control group, and these differences were maintained three months later. chemicals, PFAS, also known as the forever chemicals. Learn why some scientists are concerned. The regulation of the chemicals has become controversial, with the states largest business lobby recently successfully suing to prevent the DNR from holding companies responsible for PFAS contamination under the states decades old Spills Law.
