ABSTRACT
Vadose zone monitoring is rapidly gaining acceptance as a means to protect human health and the environment. Several steps included in the process of designing a vadose zone monitoring system are: develop a release scenario; select instrumentation; and determine location for instrumentation. Ironically, the vadose zone modeling was a tool to support the viability of the site groundwater monitoring program that was already in place. The location of the vadose zone instrumentation depends on some of the factors, including the location of the likely release areas, the vadose zone pathways, and the environmentally sensitive areas at the site. This chapter also presents some case studies: Flow and Transport Test Facility; Landfill Monitoring; and Soil Gas Investigation.
