Biological Soil Treatment and In-Situ Groundwater Remediation for Hydrocarbon Contaminants

Abstract

ABSTRACT The paper discusses two different approaches to the remediation of contaminated soil and groundwater. The information was obtained from two case studies where these methods were utilized to treat contaminants. The first approach involves the treatment of hydrocarbon-contaminated soil with microorganisms which digest the hydrocarbons releasing carbon dioxide and water. The use of microbes in this manner is commonly referred to as biotreatment. The case study was conducted in Kenai, Alaska. The second case study involved the treatment of gasoline-contaminated groundwater through the use of active permeable barrier trench systems. Trenches were installed below the surface of the groundwater and air was pumped into the groundwater, stripping the volatile hydrocarbons which were evacuated by a vapor recovery system. Because of the low hydraulic conductivity of the soil in the area, more traditional treatment options, such as the standard pump and treat operation, were not viable alternatives. The active permeable barrier trench system is being utilized at a Halliburton field facility in Artesia, New Mexico.
