Assessment of Groundwater Quality Using Correlation Matrix in Humaydat-Region, Mosul, Iraq

Abstract

Abstract The current study deals with analyzing samples of 29 groundwater samples collected from 29 wells which are used in the Humaydat-Mosul region for irrigation, home use, and sometimes for drinking purposes. Standard water tests were carried out over the course of a year, all of which were in use. The tests included HCO3 −, CL−, Mg +2, Na +, NO3 −, Ca+2, SO4 −2, TDS, EC and the well depth with the symbol D and conducting statistical analysis method (Main Components) for the tests. The correlation matrix showed that the significant levels between the components of the study, as a result, the TDS, EC and SO4 −2 distinct roots are known for the regression equation that will connect the distinctive roots with the other components. Thus these water wells are not valid for human and domestic use and were outside the permissible limits and the viability of those wells water for agricultural use after treatment on water
