The USGS Toxic Substances Hydrology (Toxics) Program develops computer simulation and statistical models as an
integral part of the Program's field investigations. The increased knowledge
gained from the development and application of models greatly enhances the transfer value of research conducted
at the Toxics Program’s research sites and can have a significant effect on decisions related to human and
environmental exposure and remedial alternatives. Information on the types of
simulation and statistical models used by the program is available. The information presented on this page
cuts across lines drawn by individual investigations and projects so that information on the development of
models can be presented in one place.
Investigations and Research Activities
- Surface Water Modeling
- Ground Water Modeling
MOC3D simulation of MTBE at the Laurel Bay,
SC, research site, based on field and lab data of Landmeyer and others (1998); MTBE in 1994 and 1998; 1998
color map shows simulated concentration ranging from 0 to 10,000 parts per billion (ppb); contours show 100,
1,000, and 10,000 ppb concentration levels.
