Dyment, S. AND T. Kady. To HRSC or not? What a great question! Edition 84, Ellen Frye (ed.), JOURNAL OF THE NEW ENGLAND WATER WORKS ASSOCIATION. NEWWA, 1-5, (2018).

Impact/Purpose:

The article is part of a series discussing the use of high resolution site characterization (HRSC) techniques to address Leaking Underground Storage Tanks (LUST). LUSTLine http://neiwpcc.org/our-programs/underground-storage-tanks/l-u-s-t-line/ is an online publication supported by EPA's Office of Underground Storage Tanks (OUST). The 2 part series explores the use of HRSC at LUST sites identifying opportunities to expand use and improve characterization and remediation performance at these sites. Impacts include increased awareness of technical and economic benefits of using HRSC tools and strategies for State and Tribal regulators implementing delegated tanks programs, EPA's Office of Underground Storage Tanks (OUST), Brownsfield and public partners, along with private partners executing field work at LUST sites.

Description:

The article is part of a series discussing the use of high resolution site characterization (HRSC) techniques to address Leaking Underground Storage Tanks (LUST). LUSTLine http://neiwpcc.org/our-programs/underground-storage-tanks/l-u-s-t-line/ is an online publication supported by EPA's Office of Underground Storage Tanks (OUST). The 2 part series explores the use of HRSC at LUST sites identifying opportunities to expand use and improve characterization and remediation performance at these sites. This article "Part 1" of the series introduces decades of theory and research regarding non-aqueous phase liquid (NAPL) and plume behavior while highlighting findings from EPA's Superfund Remedy Report and Optimization programs on the connection between HRSC tools, conceptual site models, and potential improvements in remedy performance. Part 2 of the series will further explore State and Tribal program implementation, HRSC deployment costs and typical LUST site cost ranges established by the Association of State and Territorial Solid Waste Management Officials (ASTSWMO) to consider opportunities for expanded HRSC use.
