Impact of Climate Changes on Groundwater Quality in Al-Zubair District
Abstract
The aim of this study is to evaluate the quality of groundwater in Al-Zuber district (Basra Governorate). Analysis of the physical and chemical properties of samples taken from seven wells distributed across the study area was conducted for the study year (2019). The results of the analysis were compared with data collected for samples taken from the same seven wells for three years prior to the year in which the study was conducted (2019), these years are (2014, 2017 and 2018) during the 3 previous years of the study. The results of hydrochemical analysis of the four years compared with the Iraqi Standards (IQS) and the World Health Organization (WHO) to determine their suitability for drinking and irrigation uses. The results of comparison showed that the values of pH (7.3-8.4), electrical conductivity (EC)(4140-7000 μs/cm), total dissolved solids (TDS) (2799-544ppm), free chlorine(CL) (220-380 mg/L), sulfate (SO4) (2637-3000 mg/L), and magnesium (Mg) (100-500 mg/L) are not suitable for drinking as they exceeded the limits of the standards. However for irrigation purposes, groundwater can be used after treatment.
