Abstract

Landfill infiltration rates were evaluated for three fully closed landfills using the Hydrologic Evaluation of Landfill Performance (HELP) Model. The data utilized for this analysis were scarce due to the limited number of landfills which are fully closed with well designed leachate collection systems and with synthetic top liners. The analysis included herein represents a unique evaluation of infiltration rates utilizing field scale landfill data. Results indicate that the recommended ranges of parameters suggested through HELP documentation were adequate for simulating landfill performance. For the three landfills analyzed, the average yearly infiltration represented from 4% to 17% of the rainfall volume, and the results indicated that the infiltration rates through side slopes without synthetic liners were greater than that through the top caps with synthetic liners. Regression relationships between infiltration and rainfall were developed for different landfill designs. Results are of practical significance since they can be used by landfill operators to analyze the cost effectiveness of installing synthetic liners into the cover systems of sanitary landfills.
