Abstract: Loss of the warning odorant from natural gas by soil adsorption in underground leaks has been of concern to gas companies almost since gas odorization practices began about 40 years ago. Although soil type, moisture content, and other environmental conditions have been shown to be the dominant influences on adsorptive losses, inherent differences do exist in the soil-adsorption resistance of odorant compounds which could affect the margin of safety. Since few comparative data on odorant soil adsorption have been available, this study was conducted with the objective of determining which odorant components could be recommended for best resistance to soil adsorption.
