In a few short years, PFAS has gone from a research buzzword to a significant water industry challenge. The ongoing identification of new PFAS and their health effects and regulatory action at the federal and state levels adds uncertainty to an already complicated issue.
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 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.
Our treatment experts are ready to help with treatment technology selection and design, bringing experience from years of applied research, design, and operational troubleshooting for full-scale installations of best available technologies. We also see the need for more efficient PFAS removal and destruction and are engaged in research and developing new technologies for long term, sustainable PFAS management.
Garver is ready to be your trusted advisor and guide you through characterization of your PFAS challenge all the way to implementation of your solution.
EPA announced the final rule for PFAS, establishing legally enforceable limits for six PFAS in drinking water and a timeframe for compliance. Garver Water Practice Leader Zaid Chowdhury, PhD, PE, BCEE, explains.
Learn MoreA Colorado utility found evidence of PFAS in their source water. Learn about how they partnered with Garver - evaluating best available technologies, developing funding strategies, and more - to prepare for proposed PFAS regulations and future regulatory changes.
Learn MorePFAS 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.
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 embarked on the design and construction of the first surface water treatment facility in its history, choosing GAC is setting them up for long-term benefits.
Learn MoreAEX effectively removes long- and short-chain PFAS. AEX typically needs a smaller footprint or lower replacement frequency than GAC. Widefield Water and Sanitation District has been using AEX to remove PFAS and Garver is helping the District evaluate next generation resins and pretreatments such as nanofiltration (NF).
Learn MoreReverse osmosis (RO) and nanofiltration (NF) effectively remove long- and short-chain PFAS, salts, and other contaminants from water. Garver is working with Sherman, Texas, to expand their WTP capacity and stay ahead of PFAS regulations using RO.
Learn MoreFor 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 are actively engaged in applied research to bring emerging PFAS removal technologies into use and tackle the next PFAS challenge: destruction after capture.
As a Bureau of Reclamation pitch-to-pilot project, Widefield Water and Sanitation District and Garver are evaluating next-generation AEX resins for removing PFAS from groundwater. We’re assessing emerging technologies, including hollow fiber nanofiltration and electrocoagulation, as substitutes or pretreatment for AEX in challenging waters. And we’re collaborating with The Water Tower in Gwinnett County, Georgia, to develop analytical methods to reduce the cost of PFAS monitoring. Our work will make it easier for utilities to access underutilized water supplies, help reduce costs, and provide effective water conservation.
Garver and National Alliance for Water Innovation (NAWI) are piloting innovative RO pretreatment methods including electrochemical processes and ion-selective direct nanofiltration to decrease RO membrane fouling and reduce energy requirements. We’re evaluating the cost and performance of each pretreatment technology, and we’re establishing a platform and standardized approach for comparing the performance of innovative treatment trains. That means we’re creating more options for more utilities, so that they can find the service that best fits their needs.
Learn MoreFinding funding for water and PFAS projects is a challenge. Garver One Water Practice Leader Yuliana Porras-Mendoza shares three funding strategies and Garver’s approach to helping you get the funding you need.
Learn MoreGarver’s long partnership with the City of Norman led to Oklahoma’s first indirect potable reuse pilot, and now Garver is helping the City seek additional funding for further PFAS testing as part of that pilot.
Learn MoreWe each bring unique and valuable expertise, from control at the source, to drinking water and wastewater piloting and treatment, to how to fund PFAS projects. This is by design, so that you get comprehensive support that’s focused on the constructability and operability of designs and that minimizes ripple effects that could negatively impact your ability to meet future challenges.
