The California Environmental Protection Agency, Department of Toxic Substances Control (DTSC) is releasing a modified version of the EPA Johnson and Ettinger Model (JE Model) Excel spreadsheet for practitioners working on vapor forming chemical release sites in California. The DTSC version of the JE Model is based on the 2017 EPA spreadsheet tool (Version 6.0) and provides modifications to correct errors identified in the EPA spreadsheet and to allow for the use of DTSC-recommended model input values for toxicity factors and building parameters. The DTSC-modified JE Model spreadsheet also includes a refinement of the algorithm to calculate vapor transport across the capillary fringe. A user’s guide has also been prepared to provide additional information on the DTSC modifications to the 2017 USEPA spreadsheet.

The Department of Defense's Environmental Security Technology Certification Program (ESTCP) released a solicitation on January 7, 2025, requesting proposals for demonstrations of environmental and installation energy technologies. The due date for all pre-proposals is due March 6, 2025.

The next Interstate Technology & Regulatory Council (ITRC) Annual Meeting will be held on April 7-10, 2025, in Kansas City, Missouri.

The NIH Entrepreneurship Bootcamp is designed to equip life science investigators and nascent companies with specialized innovation and entrepreneurship training. The course requires no prior experience. It uses a life science-focused customer discovery process to assess customer and stakeholder needs, and teaches participants to develop stronger business models, market strategies, and commercialization plans in advance of their initial SBIR/STTR application. Registration is open through December 20, 2024.

EPA-ORD's Engineering Issue Papers (EIPs) are a series of technology transfer documents that summarize the latest information on selected waste treatment and site remediation technologies and related issues and present it in a conveniently accessible manner to the user community. EIPs are designed to help remedial project managers (RPMs), on-scene coordinators (OSCs), contractors, and other contaminated sites technical staff and site managers understand the type of data and site characteristics that are needed to evaluate a technology for a specific site, as well as ways to design and optimize a technology for a particular application. This latest EIP summarizes the current knowledge on electrokinetic (EK)-enhanced in situ remediation technologies that are available for addressing contaminants in low-permeability (low-k) subsurface environments where conventional hydraulic delivery technologies often face challenges.

The updated guidance reflects the latest, best available science to provide information that managers of PFAS wastes can use to evaluate the most appropriate destruction, disposal, or storage method among those currently available.

The Federal Remediation Technologies Roundtable (FRTR) Matrix is a user-friendly tool for screening potentially applicable technologies for a remediation project. The matrix allows you to screen 49 in situ and ex situ technologies for either soil or groundwater remediation. Variables used in screening include contaminants, development status, overall cost, and cleanup time. Detailed information on each technology is also available, including direct links to the database of cost and performance reports written by FRTR members.

AMDTreat 6.0 Beta is a computer application for estimating the long-term costs of the abatement of mine drainage discharge, commonly referred to as Acid Mine Drainage (AMD). AMDTreat 6.0 Beta can assist a user in estimating costs and sizing facilities to abate water pollution, using passive or chemical treatment technologies. Treatment systems, vertical flow ponds, anoxic limestone drains, anaerobic wetlands, bioreactors, caustic soda, hydrated lime, pebble quicklime, soda ash treatment and other systems can be evaluated.

To support EPA's Per- and Poly-Fluoroalkyl (PFAS) Strategic Roadmap, the Agency is compiling and integrating a collection of data that can be used to evaluate what is known about PFAS manufacture, release, and occurrence in communities. As part of this effort, EPA is integrating data available nationally with other information from states, Tribes, and localities that are testing for PFAS pursuant to their own regulatory or voluntary data collection initiatives. The data included in the PFAS Analytic Tools have a wide range of location-specific data and, in general, are based on national scope, and readily accessible, public information repositories.

This website provides an updated spreadsheet tool developed by the EPA for estimating indoor air concentrations and associated health risks from subsurface vapor intrusion into buildings. The tool is based on the analytical solutions of Johnson and Ettinger for contaminant partitioning and subsurface vapor transport into buildings.
