| Abstract | ||
| The experiment was carried out to determine ionic construction for preselected five wells, located in the College of Agriculture - University of Baghdad. Moreover, other principal aims were taken into consideration such examine its suitability for human and irrigation use according to world health organization, US salinity laboratory "Richards" (18) and food agriculture organization (FAO) for 1992 classification. Water samples were taking monthly on a regular intervals from the beginning of July in 2001 up to January 2012. Results observed that water content of ions for these wells varied based on its location, which directly related on each of electrical conductivity average, total dissolved salts, total hardness, potential salinity and other chemical characteristics. Therefore, all selected water wells is no longer suitable for human uses upon Iraqi standards for human uses. In agriculture term, water wells were classified for summer and winter season into C4¬S1 except well number (5) that belonged to C3¬S1 during only winter season basing on US salinity laboratory. It was also classified into moderate saline water with type primary drainage water and groundwater and increasing with problem to hard problem according to FAO 1992. On other hand, the experiment was noticed that concentrations of boron, NO3¬- and Pb+++ were low, high concentration of Zn++ which exceed the required range and demonstration ions Ca+2, Mg+2, Na+1, So4= and Cl-1 in the water wells. This study deems good indicator must be taken into account before using five selected water wells above for human and agriculture use. | ||
