Description Soil Transport and Fate (STF) presents quantitative and qualitative information concerning the behavior of organic and inorganic chemicals in soil environments. It consists of three major components: (1) the STF data base; the Vadose Zone Interactive Processes model (VIP); and (3) the Regulatory and Investigative Treatment Zone model (RITZ). It also includes the VIP and RITZ model data editors. The STF database is divided in seven files: (1) identification; (2) references; (3) chemical characterization; (4) immobilization; (5) transformation/degradation; (6) toxicity; and (7) bioconcentration. Approximately 400 chemicals are included. The immobilization file includes information concerning partitioning, immobility, and transport of the chemicals in various soils.
