Best Practices for PFAS Management: Ensuring Safe Water and Environmental Integrity Introduction Per- and polyfluoroalkyl substances (PFAS) have emerged as one of the most concerning environmental contaminants of our time. These man-made chemicals, widely adopted for their water- and grease-resistant properties, are ubiquitous, found in everything from non-stick cookware to firefighting foams. As of July […]
Understanding PFAS Engineering Firms: Navigating the Challenges in Water Treatment Introduction Few utilities have in-house expertise in PFAS treatment. Most will engage an engineering firm to characterize the problem, evaluate options, design a solution, and support funding applications — decisions that will commit the utility to decades of operating cost. Choosing the right firm, and […]
PFAS Technology Providers: Navigating Solutions for Water Treatment Challenges Introduction Per- and polyfluoroalkyl substances (PFAS) have emerged as a critical concern in water treatment, presenting significant challenges for municipalities, industries, and environmental agencies alike. As regulations tighten and public awareness increases, the demand for effective PFAS technologies has surged. This article explores the landscape of […]
Rural Water PFAS Solutions: Addressing Contaminants in Rural Communities Introduction Rural water systems face PFAS with the thinnest margins of any part of the sector: few connections to spread costs across, part-time operators, aging infrastructure, and limited access to the engineering and legal support larger utilities take for granted. The technologies that remove PFAS work […]
Small System PFAS Compliance: Navigating Regulatory Challenges and Implementing Effective Solutions Introduction Small water systems face the same PFAS limits as large utilities, with a fraction of the staff, budget, and technical support. A system serving 800 people must meet 4 parts per trillion exactly as a system serving 800,000 must, and must navigate the […]
Understanding the Cost to Comply with PFAS MCL: A Comprehensive Exploration Introduction For a water system that exceeds the PFAS limits, the question is rarely whether to act but what it will cost and how to pay for it. The answer varies enormously — from a modest wellhead installation to a project consuming a utility’s […]
PFAS Treatment Residuals: Managing the Challenges and Opportunities Introduction Every PFAS treatment system creates a second problem as it solves the first. Activated carbon, ion exchange, and membranes remove PFAS from water by concentrating it somewhere else — onto spent media or into a reject stream. That residual is now a PFAS-bearing waste, and deciding […]
Anion Exchange vs GAC: A Comprehensive Analysis of Water Treatment Solutions Introduction Anion exchange and granular activated carbon are often presented as competing options, but they remove contaminants by fundamentally different mechanisms, and that difference determines which one suits a given problem. GAC adsorbs; anion exchange swaps ions. For some contaminants only one will work […]
Emerging PFAS Compounds: Understanding the New Frontiers in Contamination and Remediation Introduction Regulation and monitoring focus on a handful of PFAS — six in the federal drinking water rule, a few dozen in standard analytical methods. The wider family numbers in the thousands. As manufacturers moved away from PFOA and PFOS, they moved toward replacement […]
PFDA Removal: Strategies for Effective Management of Per- and Polyfluoroalkyl Substances (PFAS) Introduction Perfluorodecanoic acid (PFDA) is a long-chain PFAS that appears regularly in water monitoring data but carries no federal drinking water limit. That combination — measured often, regulated nowhere at the national level — makes it a compound utilities need to understand without […]
