Cost and Performance Report for the Performance Evaluation of a Pilot-Scale Permeable Barrier at Former Naval Air Station Moffett Field, Mountain View, California

摘要

A pilot-scale permeable reactive barrier was installed at Moffett Field in April 1996 and its performance was monitored over the following 16 months on a quarterly basis. The details of this study are described in a technology evaluation report (Battelle, 1998). This document provides a brief account of the technology evaluation. The objective was to capture and treat a small portion of the West Side Plume that contains chlorinated volatile organic compound (CVOC) contaminants, primarily trichloroethene (TCE), cis-1,2 dichloroethylene (cis,1,2-DCE), and perchloroethene (PCE). The reactive cell in the funnel-and-gate type barrier is composed of granular zero-valent iron, a strong reducing agent.
