Garver is ready to help you effectively manage PFAS
In a few short years, PFAS has gone from a research buzzword to a significant water industry challenge. Through extensive testing and analysis, we now know the PFAS issue is widespread. Approximately 2,000 of the 10,000 water systems that recently monitored for PFAS under the Unregulated Contaminant Monitoring Rule will likely need some action to comply with the new standards from the EPA.
Each water system’s PFAS challenge will be unique and multifaceted. Effective solutions will start by determining where and how to most efficiently address PFAS, whether by preventing PFAS from entering the system altogether or installing PFAS removal processes in treatment facilities, like granular activated carbon (GAC), anion exchange (AEX), and reverse osmosis (RO), and managing PFAS-laden media, residuals, or biosolids.
Bringing experience from years of applied research, design, and operational troubleshooting for full-scale installations, Garver stands ready to assist utilities with treatment technology selection and design. Garver is also engaged in cutting edge research on PFAS destruction technologies. As your trusted advisor, we will guide you through characterization of your PFAS challenge all the way to implementation of your solution.
How water utilities can achieve compliance with new EPA regulations
In the first ever drinking water regulation for PFAS, EPA has decided to regulate two of the compounds (PFOA and PFOS) at 4.0 parts per trillion (ng/L) Garver Water Practice Leader Zaid Chowdhury, PhD, PE, BCEE, explains.

How water utilities can plan for proposed PFAS regulations
A Colorado utility found evidence of PFAS in its source water. Learn about how this utility partnered with Garver to evaluate best available technologies, develop funding strategies, and prepare for proposed PFAS regulations in an evolving regulatory environment.
Learn MoreWe deliver proven treatment solutions for removing PFAS that fit the unique needs of utilities
PFAS treatment may be a new challenge, but we are proven experts with well-established treatment technologies that remove PFAS from drinking water, wastewater, and stormwater, such as granular activated carbon (GAC), reverse osmosis (RO), nanofiltration (NF), and anion exchange (AEX). Read about how we’ve delivered these proven treatments to our clients in the projects outlined below.
Granular Activated Carbon (GAC)
GAC captures PFAS, particularly long-chain compounds, on its surface and simultaneously removes other trace contaminants and natural organic matter. As the City of Enid, Oklahoma, embarked on the design and construction of the first surface water treatment facility in its history, choosing GAC set the City up for long-term treatment reliability.

High-pressure Membranes
Reverse osmosis (RO) and nanofiltration (NF) effectively remove long- and short-chain PFAS, salts, and other contaminants from water. Garver is working with the City of Sherman, Texas, to expand its WTP capacity and stay ahead of PFAS regulations using RO.

For years, we’ve been incorporating the best available technologies into robust treatment processes that can be adapted to meet future regulatory requirements and customer expectations.
We’re researching and developing technologies to benefit utilities facing all PFAS challenges
We are actively engaged in applied research to bring emerging PFAS removal technologies into use and tackle the next PFAS challenge: destruction after capture.
Piloting innovative RO pretreatment methods with NAWI
Together, Garver and the National Alliance for Water Innovation (NAWI) piloted innovative RO pretreatment methods, including electrochemical processes and ion-selective direct nanofiltration, to decrease RO membrane fouling and reduce energy requirements. We evaluated the cost and performance of each pretreatment technology and established a platform and standardized approach for comparing the performance of innovative treatment trains. That means we created more options for more utilities, so that they can find the service that best fits their needs.

We’re helping the first indirect potable reuse pilot in Oklahoma find additional funding
Garver’s long partnership with the City of Norman led to Oklahoma’s first indirect potable reuse pilot. Now, Garver is helping the City seek additional funding for further PFAS testing as part of that pilot.
