Design and analysis of a SVE system in a shallow water table application

Cummins Southeastern Power, Inc. (CSPI) operates a diesel engine repair facility in Hialeah Gardens, FL. Parsons Engineering Science, Inc. (Parsons ES) was retained to design a treatment system to remediate soil and hydrocarbons beneath the CSPI service building. Soil vapor extraction (SVE) followed by bioventing was selected as the most appropriate and cost effective approach. These activities were completed as part of CSPI's overall environmental program, which includes cleanup of any contamination that is encountered at their facilities and continual implementation of new measures to prevent future contamination from occurring. This paper presents a complete case history outlining the unique technical challenges associated with the CSPI site conditions. The methods utilized during completion and analysis of the pilot test are discussed and a description of how the pilot data was utilized for completion of the full-scale design is included. The paper presents the empirical analysis method which was developed during this design and shows how it can be applied to other SVE remediation applications
