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 regene...

"EPA" PFAS Drinking Water Treatment Technologies

Below is from a webinar offered by the EPA.    "EPA evaluated technologies and has studies that demonstrate effective removal of all regulated PFAS.  EPA has identified the following as best available technologies." Granular Activated Carbon   (GAC) Anion Exchange (AIX) Nanofiltration (NF) and Reverse Osmosis (RO) The above three are great for point of use, but not for point of distribution. So back to my earlier blog.  Why would the EPA recommend solutions that would be ideal for an individual home, but just about impossible for a large municipal water district to achieve.  So what do we do? The recommended technology is ideal for individual homes.  Taking control of the responsibility of our own water quality is the best way to ensure the quality of our water.  Some one told me and it makes sense, "if your water is not organic, then you are defeating the purpose."

EPA Plan to remove PFAS "Activated Carbon"

 Activated carbon treatment is the most studied treatment for the PFAS removal.  Activated carbon is commonly used to adsorb natural organic compounds, taste and odor compounds and synthetic organic chemicals in drinking water treatment systems.  Adsorption is both physical and chemical process of accumulating a substance such as PFAS, at the interface between liquid and solids phases.  Activated carbon is an effective adsorbent because it is a highly porous material and provides a large surface area to which contaminates may absorb. (Now keep in mind the other contaminates that will be adsorb.  This will take up surface area of the carbon shell.)  Activated Carbon is made from organic materials with high carbon contents such as wood, lignite and coal. (GAC = Granular Activated Carbon) GAC has been shown to effectively remove PFAS from drinking water when it is used in a flow through filter mode AFTER particulates have already been removed.  ( This mea...
