By its constructive characteristics, the Danube - Black Sea Canal is one of the most important constructions of this type in Europe. Its construction, the execution of the water captations' works in Caragea, Caragea Dermen, Eforie, Costinesti, Basarabi, Valul lui Traian, Medgidia etc. and the existence of the irrigation system have modified the natural hydrogeological conditions of the aquifer system. There are many pollutant sources along the canal, which in the case of an accident can have a powerful impact on the canal water, and this, on its turn, can become a secondary pollution source.
For establishing the effect of the anthropic factors on the quality of the underground water within the area of the Danube - Black Sea canal, it was realized: a chart of the phreatic level variations from the canal area, the hydrochemical monitoring of the canal and standpipes water, as well as a simulation program of the pollutant transport to the potable water captations.
