Primary 1 and Support Models for Analysis of Mercury Fate available from EPA - Athens SERAFM – Mercury Risk Screening Model WCS (MLM) – Watershed Loading Model GBMM – Grid-Based Watershed Loading Model WhAEM2000 – Groundwater Flow Model WASP7 – Water Body Pollutant Fate Model EFDC – Water Body Hydrodynamic Model BASS – Aquatic Food Web Model 1 Simulates mercury explicitly.

Watershed Mercury Models Watershed Characterization System, Mercury Loading Module – WCS MLM  Current available model  Grid soil calculations, sub-watershed loading resolution  Simple hydrology, erosion, mass balance  Provides yearly-average concentrations, loads Grid-Based Mercury Model – GBMM  Projected Availability: January 2006  Fine grid resolution  Simple wetland and tributary transport and transformation algorithms for mercury  Provides daily concentrations, loads  Future incorporation into BASINS toolkit

Water Body Mercury Models SERAFM:  Process-based, Steady-State Lake/Pond Model  Enhanced version of IEM-2M from Mercury Report to Congress  Stand-Alone model developed for Risk Assessors  Incorporates Watershed Runoff and Erosion, Mercury Cycle Chemistry, Bioaccumulation, and Wildlife/Human Risk Values  Provides yearly-average concentrations, loads  Serves as a Repository for Updates in Mercury Science and Modeling WASP7 and WASP7 Mercury Module:  Dynamic, Process Modeling Framework  General design for modeling contaminant fate and transport in surface waters  Compartment Modeling Approach, Lakes/Ponds/Rivers  Incorporates Mercury Module  Is being updated to incorporate SERAFM Science  Model architecture is being updated and improved
