Federal Facilities Online Academy: Groundwater Policy Overview, August 26, 2026, 1:00PM-3:00PM EDT (17:00-19:00 UTC). Groundwater Policy and Federal Facilities Overview is a two-hour webinar course that provides an overview of U.S. EPA groundwater policies and guidance with emphasis on cleanups at federal facilities. By taking this course, participants will achieve the following objectives: Identify EPA groundwater policies; Understand groundwater classification and beneficial use in restoration objectives; Understand nature and extent considerations from groundwater contaminant plumes; Explore applicable or relevant and appropriate requirements (ARARs) commonly associated with groundwater remedies; Identify groundwater considerations for monitored natural attenuation (MNA), institutional controls, and technical impracticability waivers; and, Discover information on major groundwater policies from other federal agencies, such as Department of Defense (DoD) and Department of Energy (DoE).

ITRC: Reuse of Solid Mining Waste, September 3, 2026, 1:00PM-3:00PM EDT (17:00-19:00 UTC). Solid mining waste represents a significant quantity of waste material in the United States and around the world. Solid mining waste has a range of physical and chemical properties that make it both potentially valuable and potentially hazardous to human health and the environment. From a commercial perspective, mining removes most of the primary minerals of interest; however, waste materials can still contain valuable minerals and other materials that can be recovered. The ITRC Reuse of Solid Mining Waste training and guidance document is geared towards state regulators and environmental consultants, mining and manufacturing stakeholders, community and tribal stakeholders, and other who have an interest in the potential reuse of solid mining waste. For more information and to register, see https://www.itrcweb.org or https://www.clu-in.org/live.

Treatment Technologies for Mining-Influenced Water: Review of Non-Peer-Reviewed Performance Data (EPA 600-R-25-190). EPA’s Office of Applied Science and Environmental Solutions (OASES) compiled this report to assist EPA’s Office of Land and Emergency Management and remedial project managers in determining what technologies may be appropriate at metal mining CERCLA sites. The full report and Appendix A: Treatability Study Performance Data and Other Key Information, including a searchable tool for case studies, are available at https://clu-in.org/products/miw.

CL:AIRE PFAS Site Profiles The profiles represent an understanding of PFAS uses and occurrences from specific industry sectors at the time of writing.

NOTE: For TechDirect, we prefer to concentrate mainly on new documents and the Internet live events. However, we do support an area on CLU-IN where announcement of conferences and courses can be regularly posted. We invite sponsors to input information on their events at https://clu-in.org/courses . Likewise, readers may visit this area for news of upcoming events that might be of interest. It allows users to search events by location, topic, time period, etc.
