Integration of Historical and Recent Data for 3D Conceptual Site Modeling and Quantitative Assessment of Contaminant Evolution in the Mantua Lakes, Italy

A comprehensive analysis of the Mantua Lakes, Italy, reveals significant reductions in sediment contaminants such as cadmium and hydrocarbons over time, with arsenic and chromium showing localized variations. The study integrated historical (2008) and recent (2024–2025) data—totaling over 2000 points—to construct a 3D geological model and estimate contaminant masses. Findings indicate strong bioattenuation in surface waters, mirroring sediment trends. This approach demonstrates the value of combining historical datasets with modern sampling to enhance Conceptual Site Models (CSMs), providing quantitative insights into contaminant dynamics and natural attenuation processes for sustainable site management.
