A remediation program at a chemical manufacturing plant is being implemented to restore the subsurface contaminated with volatile organic compounds (VOC). The remediation program consists of the removal of VOC contaminated soil (hot spot) and the corrective actions for the contaminated subsurface, being hydrogeological characterization, contaminant behavior and plume dynamics by ground water quality monitoring, ground water extraction by recovery wells and accompanied by treatment of the extracted ground water prior to disposal, and performance evaluation modeling. The initial assessment of the ongoing pump-and-treat remediation produces the expected results projected during the initial feasibility study. The location of the recovery well system seems to be effective in enforcing the contaminants out of the plume, preventing the contamination from migrating beyond existing boundaries. There has been reductions in the concentration of some contaminants in the affected subsurface; however, the goal of reaching strigent health-based cleanup standards in remote. Current case study of the VOC contaminated subsurface remediation would lead to a better understanding of the complex chemical and physical processes controlling the movement of contaminants through the subsurface, and the ability to pump and treat such VOC contaminated ground water. Understanding these processes permits the use and development of a better characterization technology for contaminated soils and subsurface, and the design and implementation of more effective and efficient contaminated soil remediation programs.
