"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."

Bacteria Resistant To Last Resort Antibiotic Found For First Time In Los Angeles County Wastewater

  Bacteria that renders colistin, a “last resort” antibiotic, ineffective are lurking in SoCal’s wastewater. While bacteria resistant to colistin have been found elsewhere in the world, this marks the first detection in Los Angeles wastewater. The bacteria and associated genes that provide resistance to colistin were discovered at the county’s two largest wastewater plants. One treatment center serves 4 million residents, the other serves 3.5 million. The resistant bacteria and associated genes were discovered by Adam Smith, a professor in the Sonny Astani Department of Civil and Environmental Engineering, and documented in a new paper published in Environmental Science & Technology Letters. Smith, who documented COVID’s presence in wastewater during the pandemic, admits this type of antibiotic resistant gene has been found elsewhere in the world (6 of 7 continents, he said) but this is first time there are traces of this particular antibiotic resistance in LA. Smith says that ...

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...
