Understanding the Total Oxidizable Precursor Assay: A Comprehensive Review for Water Quality Professionals Introduction Standard PFAS analysis measures a fixed list of target compounds — 25 in EPA Method 533, 18 in Method 537.1, 40 in Method 1633. But thousands of PFAS exist, and many of them are precursors: polyfluorinated compounds that are not on […]
Rapid PFAS Test Kits: Advancing Our Fight Against Contaminants in Water Introduction Laboratory PFAS analysis is precise but slow and expensive: results typically take one to three weeks, and each sample costs a meaningful amount. That has created strong demand for rapid test kits that can give an answer in the field, in hours or […]
PFAS Screening Methods: An Expert Guide for Environmental Professionals Introduction Per- and polyfluoroalkyl substances (PFAS) are a family of thousands of synthetic chemicals, yet standard analytical methods measure only a few dozen of them. That gap creates two practical needs. The first is speed and cost: investigations often involve many samples, and screening can identify […]
Paper Mill PFAS Discharge: Challenges and Solutions in Mitigating Contamination Introduction Paper mills have become a focus of PFAS investigation because of how some papers and packaging were historically made. Mills producing grease- and water-resistant paper — food packaging, fast-food wrappers, and similar products — used PFAS-based treatments to achieve those properties. PFAS from these […]
Metal Plating PFAS Treatment: Addressing the Challenge of Per- and Polyfluoroalkyl Substances in Industrial Processes Introduction As industrial processes evolve, so too do the complexities tied to environmental management, particularly regarding hazardous substances. One of the most pressing challenges in metal plating and finishing sectors is the presence of per- and polyfluoroalkyl substances (PFAS), commonly […]
Industrial Pretreatment for PFAS: A Comprehensive Guide for Effective Management Introduction The presence of per- and polyfluoroalkyl substances (PFAS) in industrial discharge presents a pressing challenge for environmental engineers and regulatory authorities alike. As these "forever chemicals" are pervasive, resistant to breakdown, and associated with numerous health risks—including liver damage and cancer—effective industrial pretreatment practices […]
Understanding the NPDES Permit for PFAS: Regulatory Framework and Challenges Ahead Introduction As emerging contaminants, per- and polyfluoroalkyl substances (PFAS) have garnered significant attention in recent years due to their widespread presence in the environment and potential adverse health effects. The National Pollutant Discharge Elimination System (NPDES) permit program plays a crucial role in regulating […]
Community Water System PFAS: Understanding, Challenges, and Solutions Introduction In recent years, per- and polyfluoroalkyl substances (PFAS) have emerged as a significant public health and environmental concern, particularly within community water systems. These synthetic chemicals, often dubbed "forever chemicals" due to their persistence in the environment and human body, have been linked to a range […]
PFAS Water Quality: Understanding the Challenges and Solutions Introduction The presence of per- and polyfluoroalkyl substances (PFAS) in drinking water has emerged as one of the most pressing public health issues in recent years. As of July 2025, regulatory frameworks and scientific understanding regarding PFAS have evolved significantly, leading to increased scrutiny of water quality […]
Emerging Contaminants Treatment: Navigating the Challenges and Solutions in Water Safety Introduction As water safety continues to dominate the public and regulatory agenda, emerging contaminants (ECs) have become a focal point of concern for environmental engineers, municipal directors, and regulatory agencies alike. These contaminants, which include a range of chemicals from pharmaceuticals to microplastics, pose […]
