The effectiveness of in situ, aerobic biodegradation of landfill leachate has been tested by applying bioventing at a closed municipal solid waste landfill in Minnesota. A pilot test was conducted with air injection into a field of six bioventing wells for a six-month period, creating an aerobic biotreatment zone for leachate as it migrates to groundwater. Results show that an effective aerobic treatment zone can be established and maintained with organic compounds actively biodegraded, and dissolved inorganic compounds, such as metals, oxidized and immobilized. Groundwater contaminants also showed decreasing concentrations during the pilot test. This approach may, ultimately, obliterate the need for groundwater removal and treatment.
