The Soil Transport and Fate
(STF) Data Base Version 2.0 presents quantitative and
qualitative information concerning the behavior of
organic and inorganic chemicals in soil. The STF Data
Base provides users with recent information on chemical
properties, toxicity, transformation, and bioaccumulation
for hundreds of chemical compounds. It can be used by
environmental managers, scientists, and regulators
working on problems related to vadose zone contamination
and remediation. |
| Data: |
The software consists of
three major components: the STF Data Base; the Vadose
Zone Interactive Processes (VIP) Model and Regulatory and
Investigative Treatment Zone (RITZ) Model; and the VIP
and RITZ model editors. The data base includes
approximately 400 chemicals identified by chemical name
(as referenced in 40CFR Part 261), the Chemical Abstract
Service (CAS) number, and the common chemical name. The
VIP and RITZ models are one-dimensional models that are
used in predicting the fate and transport of hazardous
organic constituents in the vadose zone. The VIP and RITZ
model editors aid in the creation of input files for the
respective models and are designed to interface with the
STF Data Base. |
| Access: |
Users can obtain a copy of
the system and user manual by sending six pre-formatted
diskettes (360K minimum) to the address listed below. STF
Data Base is also accessible on EPA's homepage via World
Wild Web.
