Fate And Transport Analyses

Fate and transport models are critical components in the determination of the exposure to and risk from hazardous contaminants. Skelly and Loy has an extensive capability in the area of contaminant fate and transport analysis as well as the development of models for assessing the migration of contaminants. Our modeling experience includes the fate and transport of volatile vapors, light non-aqueous phase liquids (LNAPLs), dense non-aqueous phase liquids (DNAPLs), metals, nitrates, and roadway deicing chemicals (i.e., road salt) within soils and groundwater. The types of models that Skelly and Loy has used to help solve geologic, hydrogeologic, and environmental problems are summarized below.

API - AT 1,2,3 D - a 2D and 3D Groundwater Flow Model
API - SESOIL - a 1-D Contaminant Mass Leachability and Transport Model
Aquifer Test Pro - Aquifer Testing and Hydraulic Modeling
Aquifer Win-32 - Aquifer Testing and Hydraulic Modeling
AQTESOLV - Aquifer Testing and Hydraulic Modeling
BUFFER1 - Soil Contaminant Migration Equilibrium Partitioning Model
FLOWPATH - 2-D Groundwater Flow and Contaminant Transport Model
GRAPHER - 2-D and 3-D Graphing Program
Johnson and Ettinger - Predicts VOC Concentrations in Soils from an Underlying Source
MODFLOW - 2-D and 3-D Groundwater Flow and Contaminant Transport Model
Quick Domenico - 1-D Contaminant Transport Model (Prediction of Plume Concentrations)
PENTOXSD - Mass-Balance Water Quality Analysis Model

Skelly and Loy employs a staff of experienced geologists and hydrogeologists with extensive modeling experience. These professionals are experienced in analyzing modeling results for developing cost-effective remedial solutions. Allow us to assist you in your next project.
