The Draganesti - Sprincenata zone from Olt flood plain has a poor drainage and a large spread of the soils affected by alkalization. The ground waters have mineralization degrees between 0.7 and 8.1 g/l, electroconductivity values between 669-9500 micromhos/cm and pH values between 7.00 and 8.80. The water with NaHCO3 that has a mineralization degree below 2.8 g/l belong to the bicarbonatic mineralization stage at a mineralization above 2.8 g/l a transitional stage (with a mixed composition in which Cl- or SO4- ions are predominantly) is characteristic. In the water without NaHCO3, the bicarbonatic stage is specific at the concentration lower than 1.8 g/l, and the sulphatic one above 2.5 g/l. Between the two stages there is a transitional one. The water quality by Florea's diagram is in the most part harmful, unsatisfactory and satisfactory -unsatisfactory
