Abstract
 GIS-Based Modeling of Odor Dispersion from Biosolids Reuse Sites Track: Modeling Author(s): Eakalak Intarakosit, Mark Ramirez Wastewater biosolids applied to agricultural fields for the recycling of the nutrients can generate nuisance odors that affect the surrounding community. Communities neighboring these application sites have enacted legislation to ban the recycling of biosolids due to odors. This study is to develop a GIS-based odor model to measure the impact of biosolids odorants in reuse fields by modeling odor dispersion from the District of Columbia Water and Sewer Authority (DCWASA) biosolids land application sites. The results show the prediction maps expressed as predicted odorant area so-called sensation area defined as the area that people could potentially detect the odor. The sensation area usually occurs during low wind speed and adverse meteorological condition especially in early morning and night. The sensation area, moreover, is also sensitive to topographic features particularly elevated terrain. This study will help biosolids manager making better decision when distributing biosolids.
