ABSTRACT
Several alternatives were studied to prevent groundwater contamination
around the Kimpo landfill site in Korea using a numerical model and hydraulic
parameter measurements. The leachate flow system and pollutant transport
system around the landfill were analyzed using a numerical model. Alternatives
utilizing dewatering wells with radial collector well laterals had low
costs but resulted in low efficiency of pollutant reduction. Installing
an interception wall at the circumference of the landfill was more efficient
but had a high cost. Installing an interception wall to the second layer
was the most stable and most economical alternative.
