Air injection into the vadose zone to aerobically degrade volatile organic compounds in groundwater and inhibit subsurface landfill gas migration

摘要

This invention is directed to systems including one or more trenches or wells that include one or more perforated pipes through which a gas, such as air, can be injected into the vadose zone of ground located beyond a methaneogenic source to create a positive-pressure gas curtain and/or aerobic conditions in the vadose zone that inhibits migration of and/or facilitate the remediation of mobile volatile organic compounds that are capable of contaminating groundwater surrounding the methaneogenic source.
