Introduction For municipal water distribution engineers, the battle against water age, nitrification, and biofilm formation is constant, particularly in dead-end mains and oversized distribution networks. The deployment of Automatic Flushing Systems (AFS) has shifted from a luxury to a regulatory necessity to maintain chlorine residuals and compliance with the Safe Drinking Water Act. However, the […]
Introduction In municipal and industrial water and wastewater systems, the control valve serves as the primary mechanism for hydraulic regulation. Unlike isolation valves, which are designed for infrequent open/close cycles, control valves must dynamically modulate flow and pressure to maintain system stability, protect aging infrastructure, and ensure consistent delivery of potable water or efficient processing […]
Emerging PFAS Compounds: Understanding the New Frontiers in Contamination and Remediation Introduction Per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals,” are a class of synthetic compounds that have garnered increasing scrutiny over the past decade. With more than 4,700 variants identified, the public health implications of these compounds are stark. Recent concerns […]
PFNA in Water: Understanding the Risks and Solutions Introduction Perfluorononanoic acid (PFNA) has increasingly become a focus of concern among environmental engineers, public health officials, and regulatory agencies. This stubborn chemical, part of the broader class of per- and polyfluoroalkyl substances (PFAS), poses significant risks to drinking water sources and, consequently, human health across various […]
Comprehensive Water and Wastewater Treatment Design Guide Regulatory Framework and Compliance Standards Navigating the maze of regulations surrounding the treatment of water and wastewater can feel like trying to find your way through a cornfield blindfolded. With over 40 federal regulations and countless state laws, it’s no wonder that municipalities often feel overwhelmed. In fact, […]
Understanding GAC Contact Time: A Critical Factor in Water Treatment Efficiency Introduction Granular Activated Carbon (GAC) is an essential component of water treatment systems, widely used to remove contaminants and improve water quality in both municipal and industrial applications. Yet, one pivotal parameter often overlooked in the design and operation of GAC systems is contact […]
EPA Method 537.1: Comprehensive Guide to Understanding and Implementing Emerging Contaminants in Drinking Water Introduction As water contaminants continue to evolve, regulatory agencies have responded with increasingly stringent testing methodologies. EPA Method 537.1, established by the Environmental Protection Agency, addresses the detection of specific per- and polyfluoroalkyl substances (PFAS) in drinking water. With PFAS often […]
Water regulation is vital for protecting public health and the environment. Across the United States, various agencies set and update standards to ensure safe water quality. States and authorized tribes develop specific standards relevant to their local situations, which must be reviewed and approved by the U.S. Environmental Protection Agency (EPA). These standards are essential for […]
Water policies play a crucial role in managing and protecting one of our most valuable resources. These policies determine how water is allocated, conserved, and managed to ensure sustainability and access for all. In the United States, water policies vary by state, with regions like California having specific laws reflecting their unique water challenges. Recent efforts […]
Standards are essential in many areas, ensuring consistency, safety, and quality. For instance, the [Oregon Department of Education] Fundamentals of Water Quality Standards Water quality standards are essential for maintaining the health of ecosystems and human populations. These standards set limits on contaminants and help ensure that water is safe for various uses. Basic water […]
