What are Perfluoroalkyl Substances or PFAS?

• Per- and polyfluoroalkyl substances (PFAS) are used to make everyday products resistant to stain, heat, oil, grease, and water.

• These include: • PFOA (perfluorooctanoic acid)

• PFOS (perfluorooctane sulfonic acid)

• Carbon-fluorine bond is one of the strongest in chemistry: very stable compound!

Every Community’s Water Is Unique

• Two communities may have the same contaminant in their water, but use different water treatment solutions.

• Selecting a treatment solution should take into account each community’s individual water quality and treatment needs.

• Pilot (shown right) or bench scale testing can be used to test the effectiveness of the technology for contaminant removal before a full-scale system is installed for community’s drinking water.

• Accelerated bench scale testing can simulate months of runtime within days.

PFAS Removal Solutions: About Carbon

• Named Best Available Technology by EPA for Organic Contaminant Removal.

• Removes other organic contaminants, in addition to PFAS (e.g., personal care products, pharmaceuticals).

• Spent carbon can be reactivated and reused.• Minimal maintenance.

Why Granular Activated Carbon (GAC) Works

• GAC is a highly porous media with large surface area for contaminant adsorption.

• All carbon is not created equal.

• Performance determined by porosity and surface chemistry.

• Evoqua helps to match the user with the best performing GAC for their application.

Reactivation Heat Destroys PFAS And More

Darlington, PA *NSF 61-certified potable reactivation available

• Evoqua offers turnkey NSF potable-certified reactivation service in Darlington, PA*.

• Reactivation:

• Thermal destruction of PFAS and other adsorbed organic contaminants.

• Economical alternative to re-bedding with virgin carbon.

• Recycles a valuable resource.

• Reduces generator’s liability for the spent carbon.

Kennebunk, Kennebunkport & Wells Water District (KKWWD)

• PFOA and PFOS found in source well.

• Concentrations were below the EPA Health Advisory Limit at 50 ppt.

• KKWWD shut the well down voluntarily and looked for a treatment solution.


Page 16

KKWWD Tested Multiple Carbon Systems

• Evoqua advised KKWWD to pilot test several types of carbon to determine which performed best given their local water chemistry.

• The results showed that the Evoqua’s carbon made from coconut provided an additional 3 months of full scale run time, versus other carbons.

• KKWWD installed a full-scale high pressure vessel system to remove PFAS from the water.

KKWWD System Performs As Requested

• “Our goal now is to continuously produce drinking water with non-detect levels,” says KKWWD, Superintendent. “With Evoqua’s lead-lag system we should have no problem.”

• The impact to ratepayers is about $0.03 - $0.04/day – customers won’t see the increase for several years.

• “It’s still cheaper than buying water from an outside water utility and it keeps us independent,” Norm Labbe, KKWWD, Superintendent.

PFAS Removal Solutions: About Ion Exchange Resin

• Smaller system footprint if space is an issue.

• Lifecycle costs are easier to predict.

• Spent resin can be incinerated, destroying the contaminants (PFAS).

• Minimal maintenance.

What Is Ion Exchange And How Does It Work

• Ion Exchange, or IX, is based on the principle of exchanging a harmless ion for the contaminant.


Page 22

A Community Like Yours: Stratmoor Hills, CO

• Detections for PFAS were greater than 70 ppt.• Local Air Force Base is source of PFAS contamination.• Aquifer that supplies several communities, affected.• Treating water for:

– Perfluorooctaonic acid (PFOA)– Perfluorooctanesulfonic acid (PFOS)– Perfluoroheptanoic acid (PFHpA)

Stratmoor Hills Water District Tested Then Installed A Proven Solution

• Water district took a recommendation to use ion exchange resin.

• The configuration had been proven earlier in a community using the same aquifer source.

• Speed of delivery and a smaller footprint were required.


Page 24

PFAS levels “…pretty much nonexistent…”

• Quickly and safely installed.

• Processes 350 gpm.

• “It’s been fantastic ever since it went online,” says District Manager of Stratmoor Hills Water District.

• Removes PFAS to levels below detection limits of 2 ppt.

Emergency Treatment in Pownal, VT

• PFOA was detected in the drinking water and as a result, a district in Pownal, VT serving 150 people was put under a “do not drink” order.

• Evoqua was able to quickly mobilize a GAC system to treat the water.
