Determination of the occurrence and recoverability of free product impacting the subsurface environment has been an on-going challenge in the environmental industry. A simple and relatively inexpensive test to perform in the field is the free product bail-down test. Many authors have proposed various analysis methods using these data for the determination of different free product characteristics.

The purpose of this project was to determine the comparability and possible validity of bail-down test interpretation methods for predicting hydrocarbon hydraulic conductivity/transmissivity and true free product thickness. Bail-down test data collected from two sites were analyzed and interpreted using methods from the following authors for this comparison: (a) Bouwer and Rice, (b) Jacob and Lohman, ( c) Yaniga, ( d) Gruszczenski, and ( e) Hughes, Sullivan, and Zinner.

A consistent trend was noted in the calculated values from all three compared wells. The Bouwer and Rice hydraulic conductivities were consistently lower than the Jacob-Lohman conductivities by at least one order of magnitude. The Yaniga calculated product thickness was consistently the largest value; the next was the Gruszczenski thickness; while the Hughes et al. thickness was the smallest value.
