A Critical Review of the Modelling Tools for the Reactive Transport of Organic Contaminants

“…This tool can simulate natural attenuation processes with three options: transport without decay, first-order decay, and solute transport with immediate biodegradation and multiple soluble electron acceptors [86]. Examples of its use can be found in the work of Khan and Husain [387] and Akins et al [388]. An improved version of BIOSCREEN-AT, based on the exact analytical solution for reactive transport from a point source in three dimensions, is also available as an MS EXCEL-based spreadsheet [389].…”
