Kennebunkport and Wells Water District to Remove PFAS with EvoquaÔÇÖs Granular Activated Carbon (GAC) System

PITTSBURGH–(BUSINESS WIRE)–The Kennebunkport, ME, Kennebunkport & Wells Water District (KKWD) will
remove perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid
(PFOS) from its water source using an Activated Carbon System from
Evoqua Water Technologies (NYSE:AQUA).

PFAS is a category of man-made chemicals that have been widely used to
make products because of their stain-resistant, waterproof and/or
nonstick properties, but are not safe for consumption beyond certain
levels.

In 2016 PFOS and PFOA were detected in the Kennebunk River Well (KRW) at
levels of 50 parts-per-trillion (ppt). Although the well contained less
than the Environmental Protection AgencyÔÇÖs (EPA) recommended combined
limit of 70 ppt, officials decided against further use of the well
without a treatment system for the compounds, and closed the well as a
precautionary measure.

KKWD tested multiple types of GAC, and ultimately decided on EvoquaÔÇÖs
patented AquaCarb® 1230CX enhanced coconut-based carbon, paired with
EvoquaÔÇÖs HP1220SYS┬« high-pressure liquid-phase adsorption system.

This new system will be installed at the well site in Kennebunkport,
Maine and is scheduled to be online and treating water in time for peak
summer demand during the coastal vacation season. ÔÇ£Our initial goal was
that if we couldnÔÇÖt continuously reach non-detect levels of both PFAS
and PFOA, we would still produce drinking water with levels below that
of any regulated limit anywhere in the nation. Our goal now is to
continuously produce drinking water with non-detect levels,ÔÇØ says Norm
Labbe, KKWD, Superintendent. ÔÇ£With EvoquaÔÇÖs lead-lag system we should
have no problem.ÔÇØ

The U.S. Environmental Protection Agency (EPA) will host a National
Leadership Summit in Washington, D.C. this week to take action on Per-
and Polyfluoroalkyl Substances (PFAS). During the summit, participants
will work together to:

• Share information on ongoing efforts to characterize risks from PFAS
  and develop monitoring and treatment/cleanup techniques;
• Identify specific near-term actions, beyond those already underway,
  that are needed to address challenges currently facing states and
  local communities; and
• Develop risk communication strategies to address public concerns with
  PFAS.
