Introduction The regulatory landscape surrounding per- and polyfluoroalkyl substances (PFAS) has shifted drastically, establishing parts-per-trillion (ppt) maximum contaminant levels (MCLs) that challenge conventional water and wastewater infrastructure. For engineers and facility directors, selecting the correct PFAS Treatment Systems: Technologies for Municipal and Industrial Use is no longer an emerging consideration—it is a critical compliance mandate. […]

INTRODUCTION The promulgation of stringent regulatory limits—including the EPA’s National Primary Drinking Water Regulation (NPDWR) setting Maximum Contaminant Levels (MCLs) for PFOA and PFOS at an unprecedented 4.0 parts per trillion (ppt)—has fundamentally shifted the landscape of municipal and industrial water treatment. For engineers, treating per- and polyfluoroalkyl substances as a monolithic contaminant class is […]

Introduction: The Complex Landscape of PFAS Management The transition from regulating conventional pollutants in parts-per-million (ppm) to treating per- and polyfluoroalkyl substances (PFAS) in parts-per-trillion (ppt) or even parts-per-quadrillion (ppq) represents one of the most significant engineering challenges in modern environmental history. For consulting engineers, plant operators, and public works directors, understanding PFAS in Wastewater: […]

Managing PFAS Investigation Derived Waste: Comprehensive Strategies for Environmental Engineers PFAS (Per- and Polyfluoroalkyl Substances) have emerged as a significant environmental and public health concern over the past two decades. As regulatory scrutiny ramps up and public awareness grows, the management of Investigation Derived Waste (IDW) generated during PFAS assessments has become a pressing issue […]

PFAS Incineration Regulations: Navigating the Evolving Landscape in 2025 Introduction Per- and polyfluoroalkyl substances (PFAS), often dubbed “forever chemicals,” have come under increasing scrutiny due to their persistence in the environment and potential health risks. As cities and industries grapple with remediation efforts, incineration has emerged as a leading disposal option. However, the regulatory landscape […]

Supercritical Water Oxidation for PFAS: A Comprehensive Overview Introduction Per- and polyfluoroalkyl substances (PFAS) have become a significant environmental and public health concern due to their widespread usage and persistence in the environment. Regulatory bodies, including the Environmental Protection Agency (EPA), have raised alarms regarding the harmful effects of these “forever chemicals,” which have been […]

Supercritical Water Oxidation PFAS: A Comprehensive Approach to Eliminating Persistent Contaminants Introduction Per- and polyfluoroalkyl substances (PFAS) represent a significant environmental and public health challenge due to their persistence, toxicity, and widespread usage in industrial and consumer products. As regulatory frameworks tighten globally, municipalities and industries are increasingly required to adopt effective technologies for PFAS […]

Biosolids management has come a long way in recent years. These treated wastewater products can be used as fertilizer for crops and forests. Biosolids improve soil structure by binding soil particles together, creating stable soil with good physical properties. New ways to use biosolids are being developed all the time. Some farms use them to […]
