The proposed areas to be planted and the proposed crops were chosen randomly without any researches to study the expected adverse impacts of these agricultural projects on the environmental components. This research aimed at the groundwater aquifer in the proposed region physically and chemically by taking five water samples from water wells in the place. Represented groundwater samples taken from observation wells in the study area were tested in term of total dissolved solids (TDS), electric conductivity (EC), and (N-P-K) concentrations to be compared with the regulated groundwater standards. As a result of testing two fertilizers, it is found that the announced concentrations of (N-P-K) don’t match the real results. The real results are less than the announced concentrations, especially for the phosphorus concentration which had a real result about half of the announced concentration for both fertilizers. Although the real concentrations of (N-P-K) in the used fertilizers are less the announced concentrations, slightly pollution is found in the groundwater aquifer. The groundwater testing results in five observation wells showed that the groundwater tends to be basic, high salinity ranged between 550 and 3500 μS/cm, and Total Dissolved Solids (TDS) results ranged between 330 and 2300. Nitrate results ranged between 65 and 160 ppm, whereas phosphorus and potassium results showed that all groundwater samples met the standards and didn’t exceed them.展开更多
