Global warming promotes drought conditions in the Dobrogea region that decrease groundwater levels and increase abstraction rates in the unconfined aquifer. This study advocates the exploitation of groundwater in the zone adjacent to the tectonic blocks 5 and 10, where the Senonian aquitard ensures delays to climate change and provides protection from potential anthropogenic contaminants. Our review of the hydrogeologic and technical conditions further suggest that abstraction wells need to be developed within the Constanta city limits and Upper Jurassic-Lower Cretaceous aquifer. The characteristics are as follows: depth of the proposed screened interval is 183-212 m, hydraulic conductivity is 6.5 m/day, and optimal abstraction rate is 6.92 l/s.
