About 99% of beef production in the United States occurs in concentrated animal feeding operations (CAFOs). CAFOs fatten huge quantities of cows in very dense, contaminated conditions before the cows go to slaughter. CAFOs use innovative technology like hormones, pharmaceuticals, and advanced feed to prepare cows for slaughter as fast as possible to maximize profits. These procedures come with negative impacts, like the emission of multiple airborne pollutants and the poor treatment of cows. This thesis focuses on the spatial distribution of CAFOs and the airborne contaminants they release. Prior research on airborne contaminant dispersion from CAFOs has found that air quality is poor for communities where CAFOs exist. This thesis identifies 221 CAFO facilities in Texas and uses meteorological variables with a Gaussian plume distribution model to estimate the 2016 PM 2.5 concentrations released from each CAFO. Linear regression is employed to compare the results to measured PM 2.5 concentrations. The Gaussian plume equation is found to estimate PM 2.5 from CAFOs accurately. Close to the beef production facilities, the estimated concentrations reach up to about 759 µg/m3, which is higher than the national annual average standard range of 12 - 15 µg/m3. Finally, this thesis makes recommendations for a healthier beef industry.
