Abstract

This paper presents an overview of the geo-environmental problems confronted at the PPI Superfund site in Louisiana. Non-aqueous phase liquids (NAPLs) have been disposed of at this site in unengineered pits excavated in overconsolidated silty clay deposits of the Pleistocene era and in lagoons in the alluvial deposits during a period extending from 1964 to 1979. In total, approximately 320,000 t of waste was disposed of at the site. The total volume of deposits contaminated with this waste are estimated to be 1 million cubic meters. The site disposal history, geotechnical characteristics of the site, characterization of species, remediation alternatives considered and executed are presented together with the problems encountered. A brief account of current performance of the implemented hydraulic recovery and containment system is provided. The experience suggests that although the technique provides a temporary option in removing the free-phase NAPLs, its efficiency will decrease in time as the residual saturation levels of the deposits are reached. Technologies which may complement the process are reviewed and discussed. The results of studies investigating potential of in situ bioremediation of the chlorinated organic species at this site are summarized.
