| Abstract |
The report presents information on quantitative evaluation of the potential impact of selected parameters on output of vadose zone transport and fate models used to describe the behavior of hazardous chemicals in soil. The Vadose Zone Interactive Processes (VIP) model was selected as the test model for the study. Laboratory and field experiments were conducted to evaluate the effect of sensitive soil and model parameters on the degradation and soil partitioning of hazardous chemicals. Laboratory experiments were conducted to determine the effect of temperature, soil moisture and soil type on the degradation rate. Field-scale experiments were conducted to evaluate oxygen dynamics, through depth and time, for petroleum waste applied to soil. Results of laboratory experiments demonstrated that the sensitivity of the degradation rate to changes in temperature and soil moisture was generally greater for low molecular weight compounds and less for high molecular weight compounds. For the two soil types evaluated, soil type was more significant with regard to immobilization. Soil type was not found to have an effect on degradation kinetics for the majority of chemicals evaluated. |
