This project will consolidate regulatory values published by governing entities in the contiguous United States (CONUS) and outside the contiguous United States (OCONUS) locations where the U.S. Department of Defense (DoD) operates. The overarching objectives of this project are to (1) create a web-based environmental chemical regulatory compendium that integrates current CONUS and OCONUS regulatory criteria for specific chemicals of concern; (2) evaluate a suite of electronic publishing and data compilation tools that provide the best value and user interface (UI); and (3) publish a web-based, dynamic compendium of concise, detailed, and timely information, particularly for per- and polyfluoroalkyl substances (PFAS) and 1,4-dioxane (1,4-D).

This project aims to create an automated method for compiling and integrating current regulatory criteria and guidance or action levels for specific chemicals of concern and regulated environmental media, including soils, waters, air, biota, and tissue. Using a proven suite of open-source data science technologies, Weston Solutions, Inc. will develop web scraping code to periodically retrieve information from the identified regulatory sources. The project team will develop a tool with an intuitive, accessible global UI as part of efficient site management of PFAS- and 1,4-D-impacted sites. It is anticipated that regulatory values published in OCONUS locations may be in languages other than English and that compounds will be identified by their Chemical Abstracts Service Registry Number^® to avoid conflicting naming conventions. The project team will address the need for an accessible and comprehensive resource that enables the DoD, stakeholders, and other users the ability to access reliable, current information over the project lifecycle.

Recent legislation reflects a growing bipartisan consensus for more rapid assessment and cleanup of PFAS-impacted sites. The results of this project will facilitate more rapid project work by enabling Remedial Project Managers (RPMs) access to global regulatory values for PFAS, 1,4-D, and any other chemicals of concern. Cost savings through a reduction of person hours are expected by utilizing automated updates to create efficiencies and reduce the chance of human error possible with current resources. Moreover, the development of this tool is likely to be of substantial interest to RPMs and other end-users who will benefit from easy access to current, accurate, need-to-know regulatory information that can be downloaded into functional formats for immediate use.
