Design of the MEPAS Computed Source Term Release Module
The MEPAS Computed Source Term Release Module (CSTRM) is generally the starting module for most analyses. It requires source inventories or concentrations and uses site-specific information to simulate the contaminant source releases, provides as output contaminant mass fluxes from the source, and provides input boundary conditions to the other module types (exposure, vadose, aquifer, surface water, and air). A full description of the design parameters, as well as scientific formulations for the various models, can be found in Streile et al. 1996 (PNNL-11248) and accessed online by following this link:

Input Secifications- The Computed Source Term has no Input Specificiations

Note that CSTRM was updated in 2003 to receive contaminant fluxes in the form of air deposition and overland flows. This modification allows the user to apply the module as a secondary source term. The update is documented in a separate online report.
