摘要: Temporal Conceptual Model can enhance the long-term management of contaminated Complex Sites. This type land model is defined here as sequential or combined representation over time single conceptual models (named Snapshot Models) including contaminant evolution, most likely causes, eventual receptor changes and uncertainties. Understanding contamination behaviour in crystalline fractured rock within tropical humid regions involves several technical complexities typically requires long term management. was case a Former Supply Well area managed 20 years for reuse, located water stressed Metropolitan Region Sao Paulo. A approach voluntary developed that, together with complementary characterization activities, used to understanding, remediation monitoring its unconfined aquifer system. They indicated that concentrations multilevel wells changed intensively time. It identified distribution controlled by extensive weathering levels variations in: pumping regimes, well reconfigurations, effects stages works, influence other source areas dynamics commingled plume. The further understanding hydrogeology specific conditions allowed advancement communication stakeholders, works local reuse plans.
