ABSTRACT

This chapter includes common rules of thumb for applying or designing various technologies. These rules are general guidelines, often based on the cost-effective application of commonly available equipment. The chapter discusses many of the groundwater and Nonaqueous phase liquids (NAPL) remediation technologies transfer contaminants to a vapor stream. The general objectives for groundwater remediation, subject to site-specific considerations, are to: prevent exposure to groundwater contaminated at unacceptable levels; contain the plume; control the source; and restore the aquifer to the expected beneficial use, to the extent practicable. Groundwater remediation sometimes occurs at an industrial facility which already has a treatment plant for industrial wastewater from the facility. Fenton's reagent has been used to treat groundwater and NAPL residuals in situ. Fenton's reagent is a mixture of hydrogen peroxide and a metal catalyst, such as iron, which generates a free radical that can oxidize organic contaminants.
