ABSTRACT
Land treatment has been used as a waste treatment and management technology by United States petroleum refineries. The technology is being applied as a cost-effective alternative for soil decontamination at Superfund sites and as elements of corrective actions for contaminated soil at Resource Conservation and Recovery Act facilities. The constituents of concern are polynuclear hydrocarbons which are also found in petroleum industry waste. Operational data and removal rates are quantified for gross hydrocarbons and specific polynuclear aromatic hydrocarbons. Soils in the ZOI, in conjunction with the underlying soils where additional treatment and immobilization of the applied waste constituents occur, is referred to as the treatment zone. To simulate the proposed full-scale conditions, the pilot studies consisted of five lined 50-foot square test plots with leachate collection. The studies were designed to maintain soil conditions which promote the degradation of hydrocarbons.
