Based on frequency and type of the pollution of phreatic aquifers in urban areas
events, a standard procedure was developed. For a hydrostructure polluted with
petroleum products, a 3D conceptual model was created based on geostatistical tools
taking into account: the spatial model, the parametric model and the hydrodynamic
model [173, 175], observe the physical processes involved in water and conservative
tracer flow in an aquifer system surrounded by two lakes [107]. Due to ground-
