ITRC's Pump & Treat (P&T) Optimization training aims to summarize existing information and best practices while also developing a systemic and adaptive optimization framework specifically for P&T well-network design and management. P&T systems have been one of the most commonly used methods for hydraulic containment and treatment of contaminated groundwater at sites with large groundwater plumes. This method cleans up groundwater contaminated with dissolved chemicals by pumping groundwater from wells to an above-ground treatment system that removes the contaminants. Optimization of P&T remedies is important for maintaining contaminant removal effectiveness throughout the operation lifetime and managing the system toward an exit strategy. A strategy for routine optimization of P&T remedies is key for maintaining the contaminant removal efficiency of these systems. The goal of the training is to provide a roadmap for optimizing a P&T system and refining the remedial strategy or shifting toward another remedial approach. Pump & Treat optimization should be systematic and data-based, and the training and document aim to provide tools and direction to assist in this rigorous process.

Every region in the U.S. is experiencing record-breaking heat. More households now require home cooling solutions to maintain safe and livable indoor temperatures. While air conditioning (AC) can offer immediate relief, the rapid scaling of AC has created new vulnerabilities: rising energy bills are straining people's wallets, while surging electricity demand mounts pressure on an aging power grid increasingly prone to blackouts. What Americans need to be prepared for more extreme temperatures is a resilient cooling approach. Resilient cooling works across three interdependent systems -- buildings, communities, and the electric grid -- to affordably maintain safe indoor temperatures during extreme heat events and reduce power outage risks. This webinar will overview resilient cooling, implicated technology systems and the policies needed to affordably cool people and communities under extreme heat conditions. Participants will hear directly from experts about dimensions of access and affordability, public health, workforce development, and grid reliability.

In this candidate notice of review (CNOR), FWS present an updated list of plant and animal species that they regard as candidates for or have proposed for addition to the Lists of Endangered and Threatened Wildlife and Plants under the ESA. This document also includes their findings on resubmitted petitions and describes the progress in revising the Lists of Endangered and Threatened Wildlife and Plants (Lists) during the period 1 October 2022, through 30 September 2024. Combined with other decisions for individual species that were published separately from this CNOR in the past two years, the current number of species that are candidates for listing or uplisting is 16. Identification of candidate species can assist environmental planning efforts by providing advance notice of potential listings, and by allowing landowners, resource managers, States, Tribes, range countries, and other stakeholders to take actions to alleviate threats and thereby possibly remove the need to list species as endangered or threatened. FWS is publishing this document on 31 October 2025. They will accept information on any of the species in this document at any time. See FR for POCs.

These technologies enable better coordination, proactive planning, and swift activation of multiple stakeholder teams, ultimately strengthening your organization's resilience in an increasingly interconnected, digital landscape.

Efficiency programs seem to ignore the fact that the only reason why society uses energy in buildings is to condition people and generate domestic hot water. One would then think that all design ought to begin with the physiological and psychological needs of the occupants. However, in the real world most energy efficiency programs focus exclusively on enclosures and equipment and have superficial Indoor Environmental Quality (IEQ) requirements. The hope is that the assembled systems will deliver the desired indoor climate with the modeled energy. The flaws in this approach are demonstrated in the poor results from thousands of post occupancy evaluations. During this session, participants will learn the human sciences behind thermal comfort and air quality and how energy and exergy efficiency is the natural outcome from engineering the indoor environment using human factor design tools.

This Energy Exchange recorded session* explores various energy modeling tools, technologies, and best practices. It discusses basic and advanced modeling techniques for existing buildings using popular tools such as building simulation software, spreadsheet analysis, and computational fluid dynamics. This session also demonstrates the pros and cons of different tools and models and how to apply best practices.
