CoronaScreen

CoronaScreen is a package of three new spreadsheet-based screening models for the performance assessment of natural attenuation in groundwater. The models have a different conceptual framework and mathematical formulation for specific contaminant scenarios, but have all been developed from a fundamental new theoretical basis, which describes the evolution of contaminant plumes in groundwater in terms of the spatial distribution of (plume "fringe" and plume "core") biodegradation processes that occur over time. Three models are available within CoronaScreen, offering the possibility to estimate the maximum plume length, the time to achieve this, the plume biodegradation rate and contaminant concentration at a given compliance point. The models can be used to evaluate mixed plumes of organic and inorganic chemicals, using standard site characterisation information and groundwater quality data collected from a relatively simple network of single screen monitoring wells and multilevel sampling well.
