Light Nonaqueous-Phase Liquid Weathering at Various Fuel Release Sites
Abstract
This report, prepared by Parsons Engineering Science, Inc. (Parsons ES), presents the results of work completed to evaluate natural weathering of light nonaqueous-phase liquids (LNAPLs) resulting from petroleum releases to the subsurface environment. As part of the natural attenuation demonstration project (Contract No. F41624-92-D-8036, Delivery Order 25), the Air Force Center for Environmental Excellence, Technology Transfer Division (AFCEE/ERT) contracted with Parsons ES to perform this fuels weathering study. Of particular interest for this study is the weathering or natural depletion of benzene, toluene, ethylbenzene, and xylenes (BTEX) from free-phase product (i.e., mobile LNAPL) following a fuel release. The BTEX compounds typically are identified as fuel hydrocarbon contaminants of concern because of their solubility and resulting mobility in soil and groundwater, and their relative toxicity (especially for benzene). Of primary interest for the study were jet petroleum no. 4 (JP-4) and gasoline release sites because they are the most common fuels on Air Force installations and have high initial BTEX fractions. However, spill sites with lower initial BTEX fractions, such as JP-5 and JP-8, also were evaluated.
