Abstract:
تقع منطقة الدراسة فلكيا بين خطي طول (40= 34 - 44?) الى خط طول (40= 56 - 44?) ودائرة عرض (00=15? 33) الى دائرة عرض (00=25 - 33) وطبيعيا تقع ضمن منطقة السهل الفيضي واداريا ضمن قضاء المدائن ولخصت الدراسة ان مساحة المنطقة تغطيتهراسوبيات الزمن الرباعي والتي تعد ا | The studied area is located astronomically between Latitude 33 ? 14 - 00 to 33 ? 26 - 20 and Longitude 44 ? 34 - 40 to 44 ? 56 - 4 0 and naturally it is within the alluvial plain area, and administratively it belongs to Al - Madain District , and summarizes the study that the size of the area covered by sediments time four - wheel, which is one of the most important aquifers in the region if These sediments water tank open and that the geological environment covered by the time four - wheel sediments and steeply in from west to east and from the north to the south and the study area is located within the dry desert climate. The Results of the analysis showed the physical characteristics of the groundwater in the study area a lot of spatial differences where the value of the PH was between 6 - 8 it any neutral and alkaline, while the value of (TDS) ranged between (395 - 16280 )mg / liter while the electrical connection (EC) ranged between 483 - 20910 ) micromhos and its contrast was a clear between the wells of the study area that increased with the increasing of the depth of the wells and the high proportion ( TDS ) of the wells and the low level of nutrition. The results of the analysis of the chemical properties of the cationic ions of the groundwater showed variation in their value from one place to another : the calcium ion values ranged between (409 - 1060) mg / liter while the magnesium values ranged between (20 - 1647) mg / liter, while the sodium ion values ranged between ( 45 - 7061 ) mg / liter ,while the potassium ion values ranged from ( 1 - 75 ) mg /liter.The results of the chemical properties of the negative ions of the underground water showed differences in their values where the value of the Sulfates between 80 - 6576 )mg/Liter , the value of the Nitrates ions ranged between 0,4 - 192 mg/Liter , when the value of the Bicarbonate ranged between 233 - 253 mg/Liter , while the value of the chloride ions ranged between 89 - 1898 mg/liter.Solin and Carlof's classification was adopted to specify the origin of the underground water for 18 wells; it showed that 18 wells are sea water origin and the quality of their water Mg Cl2.The people resident in the area depend heavily on the underground water in their different uses specially the remote area from the canals and their evaluation showed their disability to be used as drinking waters and that that they are also not useful for the purposes of construction and industrial construction as the concentration of the Ions are high while most of them are good for irrigation and the water for animal drinking
