Abstract: | |
Regulatory and Investigative Treatment Zone Model (RITZ) is a screening level model for simulation of unsaturated zone flow and transport of oily wastes during land treatment. The model considers a constant water flux and downward movement of the pollutant with the soil solution, volatilization and loss to the atmosphere, and (bio-)chemical degradation. The model incorporates the influence of oil upon the transport and fate of the pollutant, and is based on a series of closed-form analytical solutions. The treatment site modeled consists of a plow zone and a treatment zone. The model assumes that waste material is uniformly mixed in the plow zone, that the oil in the waste material is immobile, and that the soil properties are uniform from the soil surface to the bottom of the treatment zone. Furthermore, the flux of water is considered uniform throughout the treatment site and throughout time, and hydrodynamic dispersion is insignificant and can be neglected. The partitioning of pollutant between the liquid, soil, vapor, and oil phases is described by linear equilibrium isotherms. Degradation of the pollutant and oil is described as a first-order process. The water content of the soil is related to the hydraulic conductivity as described by Clapp and Hornberger. As input the model requires the properties of the chemicals and oil in the waste material, the soil properties of the treatment site, the management practices, and the parameters relevant to the environment of the site. RITZ is menu-driven and facilitates interactive data entry. The program produces graphical and tabular output.
