What is ConSim?

Developed by Golder Associates on behalf of the Environment Agency, ConSim is designed to provide those concerned with the management of contaminated land with a means of assessing the risk that is posed to groundwater by leaching contaminants.

ConSim version 2.5

ConSim has a fixed conceptual site model; it is used to assess the potential for leaching of contaminants from contaminated soil followed by migration and attenuation in the unsaturated zone and subsequently the aquifer system. Dilution, retardation and biodegradation/decay may be incorporated.

Output includes contaminant concentrations (in the source, at the base of the unsaturated zone and in the aquifer at specific receptor locations), both retarded and unretarded travel times, and aquifer underflow. A tiered approach allows users to compare output at each stage with a selected Water Quality Standard, to decide the appropriate way forward.

Multiple sources, contaminants and receptors may be modelled in a single run; the source duplication function reduces the amount of repetitive data entry required. Multiple unsaturated pathways may also be included to take account of the effects that different materials will have on infiltration and contaminant migration. Soakaway (enhanced infiltration) and dual porosity options are also available.

The uncertainty inherent in the environment is taken into account through the use of parameter input ranges and a Monte Carlo probabilistic calculation methodology.

ConSim is not suitable for modelling the migration of NAPL, and does not consider risk to human health.
