Abstract. Contaminated sites can pose a significant risk to public health and the environment. Many different insitu or ex-situ remediation technologies have been developed throughout the years to mitigate the risk imposed by soil contamination. These technologies may be contaminant and site specific.
19.9.1.2 In Situ Methods. These methods perform remediation without the need to excavate the contaminated site. Reed et al. defined in situ remediation technologies as the destruction or transformation of the contaminant, its immobilization to reduce bioavailability, and the separation of the contaminant from the soil (Reed et al. 1992).
