The Association for Environmental Health and Soils (AEHS) is hosting the 40th Annual International (East Coast) Conference on Soils, Sediments, Water, and Energy in Amherst, Massachusetts from October 21 to 24, 2024. This AEHS conference integrates a variety of topics for the environmental science community and regulators. It offers an opportunity to stay updated on recent techniques and technologies for addressing environmental issues and solutions. SCS Engineers technical advisors and environmental professionals are attending the 2024 AEHS conference and are available to answer and discuss solutions for the covered topics.
PFAS
Per- and polyfluoroalkyl substances, called PFAS, is a major topic covered during the sessions. Three workshops and several presentation sessions are addressing various aspects of PFAS challenges. Sessions will cover an overview of methods and materials for field sampling activities and published sampling protocols, guidance, and procedures. They will also address various analytical methods for evaluating PFAS in drinking water, wastewater, solids, and biosolids, as well as the best practices for field collection and the available analytical methods and their applicability.
PFAS Treatment
Another significant topic will be PFAS treatment and remediation. One session covers an innovative approach combining foam fractionation with supercritical water oxidation to eliminate PFAS from various waste streams. Destructive technologies, including electrical discharge plasma treatment, thermal destruction, enhanced oxidation, and sonolysis, have shifted from the laboratory bench to the field. Therefore, one of the presentations will cover the various mechanisms used to destroy PFAS, compare early performance data to determine effectiveness and highlight successes and obstacles that may occur as these technologies move from pilot scale to full-scale implementation.
Metals Remediation and VOCs
Other topics include metals remediation, such as an in-situ chemical fixation process that co-precipitates arsenic via the formation of an iron-arsenic oxyhydroxide complex, and the remediation of lithium, molybdenum, boron, and arsenic at coal combustion residual sites. The investigation and remediation of chlorinated volatile organic compounds (cVOCs) will also be discussed in various sessions, covering the use of real-time 3-dimensional data visualization and analysis during a high-resolution site characterization, investigation using the membrane interface hydraulic profiling tool for the delineation of cVOCs and remediation using emulsified zero-valent iron for direct source mass destruction.
Regulations and Adapting Technologies for Emerging Contaminants
Other topics include bioremediation, vapor intrusion, statistics, sustainable remediation tools, climate change and resiliency, managing environmental data, in-situ remediation, and environmental security. The event dedicates one session to emerging environmental contaminants in drinking water, such as microplastics, nanomaterials, and PFAS. This session will also discuss the current status of United States regulations and provide a forecast of the potential trajectory of regulations and the corresponding legal landscape over the next one to two years.
AEHS also organizes a similar West Coast conference. The West Coast 34th Annual International Conference on Soil, Water, Energy, and Air Conference will be held March 17-20, 2025, in San Diego, California.
