Feasibility Study for PFAS Removal at Well 15

April 27, 2021 12:06 PM

There is a Water Utility Board meeting today at 4:30p. The Feasibility Study for PFAS Removal at Well 15 is agenda item #4 and you can review the full report here.

Goals of the study:

  • Evaluate treatment technologies
  • Get a general estimate of upfront and ongoing costs for effective treatments
  • Provide a recommended treatment design that would:
  • Remove PFAS.
  • Remove PCE and TCE, eliminating the need for the air stripper system that's currently set up at Well 15.
  • Allow 1000 gallons per minute of water to be produced from the well.

Study results:

A granular activated carbon system was the recommended treatment technology.

  • Granular activated carbon successfully removed PFAS, PCE, and TCE.
  • The estimated initial cost of the recommended system was $825,000.
  • Note: This is a general estimate for the treatment system only. There would be additional costs to modify the building at Well 15 because it is not tall enough.
  • The estimated ongoing costs would depend on how frequently the carbon is replaced. The preliminary estimate was $50,000 to $300,000 a year.
  • The major components for the recommended system (ex: bag filter units, steel pipes, tank) have a life expectancy of approximately 30 years.
