8.1 Introduction

A variety of passive treatment approaches for managing perchlorate-contaminated sites have been developed in recent years (Lieberman et al., 2004; Knox et al., 2005). These approaches range from simply monitoring and documenting natural physical, chemical and biological processes as they occur (monitored natural attenuation [MNA]) to creating conditions in the contamination zone that will enhance biodegradation rates. Both MNA and passive bioremediation rely on natural biological activity in an aquifer to reduce perchlorate concentrations. However, unlike MNA, passive bioremediation involves the addition of a slow release organic substrate to stimulate the indigenous microbial population.

Biologically active treatment zones can be formed in an aquifer to treat source areas or control downgradient migration of dissolved perchlorate by injecting organic substrates through injection wells in a grid formation or through lines of temporary or permanent injection wells to...
