Assessing And Remediating Low Permeability Geologic Materials Contaminated By Petroleum Hydrocarbons From Leaking Underground Storage Tanks: A Literature Review

EPA developed this document for EPA regions, states, tribes, and local agencies involved in investigating and addressing petroleum releases from leaking USTs.  The document contains a literature search focused on effectively remediating leaking UST sites underlain by low permeability geologic materials, specifically unconsolidated silts and clays.
