INTRODUCTION The API desired an evaluation of options for treating ground water containing dissolved gasoline components. In particular@ the API was concerned about aromatics such as benzene@ toluene@ xylene@ and ethylbenzene@ and oxygenates such as TBA and MTBE. These components are referred to in the report as total organics of interest (TOI). In an earlier literature search and evaluation@ activated carbon adsorption and air stripping (or a combination of these technologies) were identified as the most likely treatment alternatives. Land application was also identified as an alternative for certain applications. The API contracted with ITE to conduct a technical and economic evaluation of the alternative technologies. A laboratory evaluation of the adsorption and stripping technologies was conducted in order to identify optimum design conditions. Activated carbon adsorption was evaluated over a range of feed concentrations@ hydraulic loadings@ and regeneration conditions (the carbon was nondestructively regenerated with steam). Air stripping was evaluated over a range of feed concentrations@ temperatures@ and air/water ratios. volume One of this report details the experimental procedures and results. Based on design and operating conditions identified in the laboratory evaluations@ capital and operating cost estimates for full-scale systems were developed. Cost curves were generated over the range of design and operating conditions. The cost curves in this report are intended to be used as a treatment manual to aid in selecting the appropriate treatment technology for a particular application. These curves are included in Volume Two of this report.
