The Plan To Remove PFAS

 After listening to the plan from the EPA on how to remove the forever chemicals listed in the umbrella of PFAS, its clear the municipal water districts will have a hell of a time complying with the new regulations.

The proposed National Primary Drinking Water Regulation  is allowing the EPA to enforce its new standards for regulating the PFAS contamination in our drinking water supply.  This is all well and good, until you look at the ways and means to actually remove the contaminate.  On a large Municipal water supply, you can have tens of thousands to hundreds of thousands of customers.  The water Volume alone in a five inch or eight inch water main is tremendous.  With the high volume and flow rates, the size of the filter or the amount of media would be in the range of a half a million plus cubic feet.  Ok, lets back up a bit.

One effective way to remove the PFAS from your water supply is anion resin.  This most cost effective with its regenerative capabilities, allows for long life span of the media.  Anion Resin also removes Fluoride, Silica ( Very Common in Colorado ), Nitrate and now PFAS.  

Ok, so now considering the high volume of water that would have to be treated, this Water Man does not know of any plausible solution for a municipality to use anion resin filtration.  (Impossible) 

Granular Activated Carbon would be the same.  Size of the activated carbon media on a large scale municipal level is unattainable.  We need to consider self filtration to have a realistic chance of achieving the EPQA goals for our own safety.
