Treatment Technology Overview

Several technologies have been used to treat perchlorate contamination of soils and waters (USEPA, 2005 ITRC, 2008 Logan, 2001). Initially, ex situ technology at the wellhead was used to treat perchlorate contamination of drinking water wells. Perchlorate was removed from potable water by pumping through granular activated carbon (GAC) or ion-exchange resin developed for removal of anions. There are two types of conventional ion exchange systems (1) single-pass systems, in which the resin is...

Template Site Characteristics And Variations Considered

The template base case site represents a situation where perchlorate is present in a shallow groundwater aquifer consisting of homogeneous silty sands and each of the four technologies being considered would likely be effective. The specific site characteristics for the base case are presented in Table 10.1, along with twelve variations on the base case characteristics that were considered in the evaluation of the sensitivity of costs to the various parameters. The physical configuration of the...
