The CORONA Screening Model (CSM) is a new spreadsheet tool for the prediction of contaminant plume length in groundwater. The CSM has been used to predict the spreading of a BTEX and Styrene plume in an unconfined sandy aquifer. To test the reliability of this new software, the results gained by the application of CSM have been compared with the ones obtained with the implementation of a numerical model built using a world accepted and tested code like PMWIN. In the numerical model a coupled reactive transport model PHT3D has been used to simulate the fate of dissolved BTEX and Styrene in the aquifer.

Abstract
The CORONA Screening Model (CSM) is a new spreadsheet tool for the prediction of contaminant plume length in groundwater. The CSM has been used to predict the spreading of a BTEX and Styrene plume in an unconfined sandy aquifer. To test the reliability of this new software, the results gained by the application of CSM have been compared with the ones obtained with the implementation of a numerical model built using a world accepted and tested code like PMWIN. In the numerical model a coupled reactive transport model PHT3D has been used to simulate the fate of dissolved BTEX and Styrene in the aquifer. The model grid was intensevely tested to avoid numerical dispersion. Calibration was achieved comparing 3 data sets sampled in different water table conditions coming from MLS located along a flow line.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
