Abstract:

The Regulatory and Investigative Treatment Zone Model, RITZ, (Short 1985) was developed to help decision-makers systematically estimate the movement and fate of hazardous chemicals during land treatment of oily wastes. The model considers the downward movement of the pollutant with the soil solution, volatilization and loss to the atmosphere, and degradation. The model incorporates the influence of oil upon the transport and fate of the pollutant. This RITZ model forms the basis of this interactive software system. The software enables users to conveniently enter the required soil, chemical, environmetal, and management parameters and checks the validity of these entries. The user may then select graphical and tabular outputs of the quantities of interest.

The manual describes the basic concepts of RITZ and lists the inherent assumptions. The manual, also, describes the use of the interactive software and the hardware and software requirements for it. Illustrative examples of the software are presented. The appendix includes a list of the mathematical equations used in the software.
