ESCI - Version Bioscreen - Groundwater Transport and Fate Model
BIOSCREEN is a screening level groundwater transport and fate model and is based on the Domenico analytical model. It simulates contaminant transport based on advection, dispersion, adsorption and biological decay. Contaminant transport can be simulated: Without biological decay, With biodegradation simulated as a first-order decay process, or with biodegradation based on instantaneous reactions.
When used with SEVIEW, BIOSCREEN can be calibrated to the time-dependent contaminant load to groundwater from SESOIL. Results can be used to estimate how far a contaminant plume will migrate and can be compared to groundwater standards to evaluate risk at specific locations and times.
