Onsite Treatment of Petroleum, Oil, and Lubricant (POL)-Contaminated Soils atIllinois Corps of Engineers Lake Sites

摘要

To achieve compliance with Federal and state underground storage tank (UST)regulations, the U.S. Army Engineer District, St. Louis decided to remove USTs at Illinois lake sites. The decision was to remove, rather than upgrade, all Corps-owned USTs in the St. Louis District and replace them, where needed, with aboveground storage tanks. During the removal process, leaking USTs were identified at the Illinois lakes of Shelbyville, Carlyle, and Rend. This report documents the design and testing of methods to treat soil contaminated by POLs onsite by enhancing aerobic decomposition. The St. Louis District and USACERL developed an inexpensive, easily accomplished method for treating occasional instances of POL-contaminated soil.
