Multivariate Statistical Methods Used in Determining the Hydrogeochemical Surfaces of Groundwater in Yusufiya District

Abstract

Abstract For the importance of groundwater and being the second natural source of water after surface water, it is necessary to know the quality, features and hydrological surfaces of this water. For this reason, 15 wells were chosen in the Al Yusufiyah sub-district to study the quality of groundwater based on multivariate statistical methods as well as the Piper chart. These methods proved successful in characterizing the study of groundwater chemistry and can be relied upon for ground and surface water in other regions. The quality of the groundwater in Al Yousifiyah, according to Piper’s scheme, the alkalinity increases with the presence of sulfate and chloride, depending on the type of soil. From the analysis of the correlation matrix, the totals were found to be Ca, Mg, and Cl., Ca, Mg, Cl, and SO4, as well as Ca, Na, Mg, Cl, SO4, and HCO3. From the mass analysis, the first K, second Na, third Ca, fourth Mg, SO4 and fifth Cl, HCO3 were obtained. Finally, from the main component analysis, hydrogeochemical facies were found: Cl, SO4, Ca, HCO3, Mg, and Na, Respectively.
