The impact of urban development on water resources is a major issue. It is particularly acute for near surface urban groundwater. In Paris, these groundwater, once providing drinking water, are now disused. Understanding their present and past chemical status would be extremely useful to assess past public remediation policies and to open discussion for their use as non-conventional water resource. Determining urbanization/industrialization impacts on water quality is hampered by two majors scientific locks: i) knowing the initial (pre-urbanization) state; ii) identifying key elements and natural archives suitable to reconstruct pollution sources and levels through time.
