ABSTRACT
This chapter presents one project for which the site is unusual as the main contaminants are total dissolved solids. A hydrogeologic investigation was conducted at the site to evaluate conditions for the installation of monitoring wells to comply with the requirements of the Resource Conservation and Recovery Act. Various technologies were considered for remediation of the ground water at the site. Because of the low permeability of the soils, more than 75 wells were required to completely capture the contaminated plume. Direct evaporation and reverse-osmosis (RO) were selected for cost evaluation. The dual-stage RO/evaporator was selected as the preferred treatment system. Another step in the project is to run a pilot plant study on the RO system. This test will confirm the design parameters, and evaluate the performance of the various membranes on the specific compounds detected in the ground water.
