| Abstract | ||
| In the present study, ground water samples were gathered from differentregions located inHillacity during period from October 2014 to September ,2015. Water samples were taken from ten wells (monthly two samples from each well) in different regions for analyzing laboratory for thirteen parameters, they are: Temperature, pH , Electrical conductivity (EC), Total hardness (TH), Calcium (Ca+2), Magnesium (Mg+2), Chloride (Cl-1), Sulphate (SO4-2), Nitrate (NO3-), Sodium (Na+), Potassium (K+) and Total Dissolved Solid (TDS) . The evaluation of water suitability of the present study for drinking and other irrigated purposes was achieved by means of arithmetic method of WQI depending on guideline values of (WHO,2004) and Iraqi Standard No.417 for (2004) . Values of WQI ranged from (97.230 - 79.100)at Hilla city which is not suitable for human consumption according to the classification of Iraqi Standard No.417 for (2004) and WHO ,2004. These values belong to high water electrical conductivity and chloride of the studied wells comparable with other parameters. Also, correlation coefficient supports this interpretation where there are strong positively correlation between WQI values and both electrical conductivity and chloride values (0.997, 0.919 respectively).While in the assessment of ground water quality for irrigation, electrical conductivity, pH, sodium absorption ratio (SAR), chloride,slphate, sodium, calisum and magisumwere used to calculateWQI values which range from (98.074- 83.187). These values are associated with both EC and Cl- in a strong negatively correlation (-0.968, -0.969 respectively). Application of Visual Basicsoftware is a good tool to explain the WQI index for all types of rivers and streams in Iraq, that will be useful to give fast indication about WQI index | ||
