Risk management, modelling, and assessment tools, for waste management, built for and with the Environment Agency.

For further information on any of the tools listed below, or to purchase or renew licences, please contact the individual toolset’s helpdesk email addresses.

ConSim

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 models contaminant leaching, migration, and attenuation, and provides contaminant concentrations and travel times as output. It uses a Monte Carlo probabilistic calculation methodology to account for uncertainty. ConSim is not suitable for modelling NAPL migration or assessing risk to human health.

LandSim

The LandSim program uses MonteCarlo probabilistic performance assessment to model new and existing landfill sites.

The model tracks leachate production, chemistry, migration and leakage through engineered and non-engineered structures, and leachate migration through the unsaturated zone to assess impact on the aquifer.

GasSim

GasSim simulates the fate of landfill gas arising from managed or unmanaged landfill sites.

It uses information on waste composition, landfill engineering, and gas management techniques to assess control measures. Outputs include estimates of gas generated, emissions, air quality impacts, and human exposure to trace constituents.

The Environment Agency requires risk assessments for landfill operations, which can be done using GasSim or other validated models. GasSim has been developed for the Environment Agency to provide a systematic approach, while other models may require justification and validation before being accepted.

WRATE

WRATE is a tool used to assess the environmental impacts of waste management activities, allowing users to track impacts from collection to disposal. WRATE allows the user to add user-defined processes and waste composition, allowing waste managers to model their own waste management systems more realistically.

Due to the simplicity of its graphical user interface, the tool improves communication between the various stakeholders involved in the development of new waste management infrastructures. WRATE is designed by those involved with waste management planning and who are involved in the day-to-day decision making associated with waste management master planning.
