Hydrogeochemistry Study of Groundwater and Identify their Origin in the Region Surrounding of Ramadie City in Al - Anbar Province, Iraq
Main Article Content
Abstract
Hydrogeochemical study and identify the origin of water wells were curried out in the region surrounding of Ramadie city in Al-Anbar province, Iraq. Results of the study showed that the groundwater in the study area mostly is very hard and alkaline nature as hardness values ranged 324.2 to 1763.5 and as pH values ranged 7.12 to 7.81 respectively. It has conducted a test of accuracy of the chemical analysis for collected water samples and shows it's very accurate and within the permissible limits and reliable in the chemical interpretation. In the present study "Piper diagram" have been used for manipulating analytical data to estimate the chemical type of groundwater in the study area. Depending on this diagram the groundwater in the study area is considerably dominated by Sulfate type and four hydrochemical facies of water have been detected. These facies are "Na+- SO42- ", "Na+- Cl- "," Mg2+- SO42- " and " Ca2+- SO42- ". To decide the groundwater origin of hydrochemical functions such as rCa / rCl rMg / rCl, rNa / rCl, rK / rCl, and rSO4 / rCl in the studied water samples have been calculated and compared with the standard values of the seas and oceans waters. The result shows that the origin of the water in the study area is infiltrated meteoric.
