The goal of this project is the development and demonstration of simple, low-cost, and accurate methodology that can be used in place of currently mandated approaches to obtain fumigant emissions estimates. Essentially, laboratory and modeling studies will be carried out using soils from the Buttonwillow, CA field site, and compated directly to the previously completed field experiments. As in the field experiment, the simplified methodologies will be applied to current fumigation practices and to new reduced-emission strategies. Additionally, a wide range of additional emission reduction strategies will also be assessed, with some of these experiments to be determined in collaboration with California ARB and stakeholder groups. A principle advantage to carrying out so many, differing, studies at a single site will be that our understanding of the important processes controlling fumigant fate and transport will not be clouded by inter-site differences, which has been a problem in previously conducted studies.
