Modeling Methodology for Determing Odor Dilutions to Community Odor Threshold Values of Odor Causing Compounds at Sanitary Landfills

Abstract

This study is to provide reasonable guidance for evaluating acceptable community odor threshold, and to develop a method for evaluating odor dilutions to community odor thresholds associated with appropriate horizontal isolation distances. The one odor unit strategy incorporated into modeling and analysis provides reasonable criteria for evaluating alternative horizontal isolation distances at sanitary landfills. For effective odor reduction, this study suggests that horizontal isolation distance must provide at least 10³dilutions from the original concentration to render odorous compounds odorless.
