On October 16, 2025, OLEM issued a directive providing updated guidance and establishing a new approach to accelerate cleanup of lead contaminated soil on residential properties at CERCLA (also known as Superfund) sites and Resource Conservation and Recovery Act hazardous waste cleanup facilities.

The directive establishes:

• A regional removal management level of 600 parts per million for lead in residential soil.
• A regional screening level of 200 parts per million for lead in residential soil.


• A target children’s blood lead level of 5 micrograms per deciliter to determine preliminary remediation goals.
• A series of process improvements to accelerate response actions.

This directive supersedes the January 2024 Updated Soil Lead Guidance for CERCLA sites and RCRA Corrective Action Facilities.

This report reviews technology screening for recovering critical minerals (CMs) from mine wastes and mining-influenced waters, focusing primarily on Rare Earth Elements (REEs). It identifies REEs, along with cobalt (Co), lithium (Li), and antimony (Sb), as key CMs, noting their strategic importance and potential for extraction from mining and mineral processing waste. This work aims to enhance the efficiency and sustainability of remedial actions at Superfund mine and mineral sites, including abandoned mine lands, by identifying technologies that facilitate CM recovery. It also highlights challenges in the recovery of REEs due to their chemical similarities and emphasizes the need for continued research to support sustainable mineral resource management.

The purpose of this RFI is to gather information from industry in the preparation for an upcoming solicitation for the Superfund Analytical Methods (SFAM02.0) under the Contract Laboratory Program (CLP). The NAICS Code for this requirement is 541380 - Testing Laboratories and Services. Responses are due by 4:30 PM ET on June 5, 2025.

EPA provides several types of free technical assistance to support local efforts to address Brownfield sites. Available support activities include those conducted by the Technical Assistance to Brownfields (TAB) Program located at the five regional Hazardous Substance Research Centers. Direct support is available to EPA regional staff, state staff, and local governments.

EPA prepares the Superfund Remedy Report to provide information and analyses on remedies EPA selected to address contamination at Superfund National Priorities List and Superfund Alternative Approach sites. This report is the latest in a series, prepared since 1991, on Superfund remedy selection. The latest edition focuses on the analysis of Superfund remedial actions selected in fiscal years 2021, 2022, and 2023.


The data that forms the basis of the analyses contained in SRR 18th Edition can be found at Superfund Data and Reports by downloading Contaminant of Concern Data for Decision Documents by Media and Remedy Component Data for Decision Documents by Media.

The Interstate Technology & Regulatory Council (ITRC) is now accepting proposals for new Project Teams to launch in 2026. The deadline to submit a proposal is May 27, 2025.

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 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.
