The ASTSWMO Investigation and Remedy Selection Focus Group with the assistance of US EPA have developed the following Quick Reference Guide for State staff. The goal of this Quick Reference Guide (QRG) is to serve as a practical, step-by-step guide for using Spreadsheets for Environmental Footprint Analysis (SEFA), a tool developed by the U.S. Environmental Protection Agency (EPA) to help quantify the energy and resource demands of proposed remedial activities. SEFA may be used to aid in the remedy selection process by determining key project metrics and asset usage such as fuel and energy use, water consumption, and material use (import, export, reuse, and disposal). These metrics are helpful when comparing remedies to determine the most efficient and economical remedy components. SEFA is intended for use by project managers, engineers, field coordinators, and analysts involved in planning, executing, or closing out site remediation projects. The following presentation was given at the 2026 ASTSWMO Mid-Year meeting to help walk through how to use the SEFA tool.

The ASTSWMO Investigation and Remedy Selection Focus Group has developed a Quick Reference Guide for State managers. The goal of this Quick Reference Guide (QRG) is to support the development of Community Considerate Cleanups (C3). These are cleanups designed through the lens of the people who live, work, play, and learn in an affected community. Communities are affected not only when cleanups take place within them, but when cleanup waste is treated and/or disposed of in the area.
Note: The QRG is not intended to be a comprehensive guide for all cleanup plan requirements, but rather a pathway to re-frame the importance of addressing community voices within the cleanup plan. This QRG does not replace federal or State public participation or cleanup planning requirements, but rather serves to provide additional depth to existing proven practices.
The Investigation and Remedy Selection Focus Group developed this assessment screening tool with the intention of helping regulators review risk assessments that do not fit typical residential or commercial/industrial scenarios. These atypical situations, selected with States feedback, include exposures from trespassing, recreating, or short-term work assignments, etc. This tool helps reviewers determine if the variables used are within reasonable ranges and what variables have the highest impact on the ultimate outcome of a risk assessment.
The ASTSWMO Investigation and Remedy Selection Focus Group provides a snapshot analysis of climate change attempts to evaluate existing science from mainly governmental sources in their effects on possible changes of contaminant character and distribution.
The ASTSWMO Sediments Focus Group has produced this document that discusses causes and issues related to recontamination. Discussion topics include new contamination of sediment sites from both known sources and newly identified sources, including contamination from new chemicals or those not addressed in previous assessments, and identification of pollutants most commonly found in areas where recontamination has occurred. Also included are case studies at sediment remediation sites where inadequate source control and/or recontamination have been documented after remedy efforts have commenced.
