Introduction Designing systems for Agricultural Wastewater Treatment: Methods and Best Practices represents one of the most formidable challenges in the environmental engineering sector. Unlike municipal sewage, which typically presents with Biochemical Oxygen Demand (BOD) in the hundreds of milligrams per liter (mg/L), agricultural effluents—from Concentrated Animal Feeding Operations (CAFOs) to meat processing plants—routinely exhibit BOD […]

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 […]

Comparing PFAS Removal Technologies: A Comprehensive Analysis Introduction In the rapidly evolving landscape of environmental engineering, the need to address per- and polyfluoroalkyl substances (PFAS)—widely recognized as ‘forever chemicals’—has become an urgent priority. These substances are prevalent in various industrial applications and consumer products, with their persistence in the environment raising significant health concerns. Recent […]

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 […]
