Abstract

A former industrial area, used for the temporary, non-covered storage of chlorinated organic solvents, has been subject to a hydrogeological investigation and assessment, in order to evaluate the relevance of the existing contamination in the soil and groundwater. The local water table is shallow (~2m deep), and the sedimentary upper aquifer presents clayey to silty composition and low to very low hydraulic conductivity of less than ~10-5 cm/s. The primary contaminants are chlorinated hydrocarbons (1,2-DCA) and aromatic hydrocarbons (BTEX), with local occurrence of LNAPL. The contaminants have partially reached the deeper aquifer of igneous composition, which is locally used for industrial purposes. Based on the mathematical modeling, risk-based remedial actions were proposed and remediation goals w
