PFAS constituents have been detected in the hydrosphere, with detections in the Himalayan plateau above current EPA RSLs.
Use of PFAS in manufacturing has been decreasing since the early 2000s, but legacy contamination of PFAS is an issue, and current disposal methods are "learning as they go" so to speak.
We will be dealing with this class of compounds for a long time, and as with early contaminants in the 80s/90s (TCE, VOCs) we will likely see revised health advisory limits as more research is conducted into their lifetime exposure limits. Basically, these are the "hot" new containment and they are hard to degrade, we will be dealing with them for a long time.
