Abstract
Groundwater in Yusufiyah represents the main water source for drinking and irrigation purposes in the dry season, so this research was conducted to assess and evaluate the hydrochemistry of groundwater in this area. (15) wells were selected for sampling in this area with depth ranges between 10-20 meters. , Groundwater generally flows from east to west and from northeast to southwest.Physical parameters for water samples were measured included temperature, pH, electrical conductivity (EC), and total dissolved solids (TDS),where the chemical parameters included major cations (Ca+2, Mg+2, Na+2, and K+) and major anions (NO₃^-1, SO₄^-2,Cl^-, and HCO₃^-). The results indicated that groundwater in the study area isnot suitable for human drinking due to high concentrations in(CL=435 ppm), (SO4^-2=769 ppm), (HCO^-3=280 ppm),(TDS=2375 ppm), and (EC=2899µc). These values exceeded the standard limits of WHO. On the other hand, results show that this water was suitable for irrigation (good and Permissible except for well no.1,8,12,13, which wasnot suitable for all irrigation crops due to an increase in (SAR, Na) to the Don classification 1995.
Highlights
Most wells in the study area have water types of NaCl and MgSO4, and the other wells are CaCl2 and Na2SO4.  Groundwater in Al-Yusuifyia district is not suitable for drinking due to the high concentration of CL, SO4, HCO3, and TDS, EC..because they are exceeded the standard limit of WHO.  For irrigation purposes, the well water is considered good and permissible.
