GEOSPATIAL TECHNOLOGY FOR GROUND WATER QUALITY PARAMETERS ASSESSMENT IN DHI-QAR GOVERNORATE-IRAQ BY USING (GIS)

Groundwater serves as the main sources of water in the urban environment, which is used for drinking, industrial and domestic purposes and often, it is over exploited. Now a days, the groundwater is facing threats due to anthropogenic activities. In this study, groundwater samples were collected in four different seasons from 25 wells drilling in Dhi-Qar district. The water samples were analyzed for physico-chemical parameters like TDS, Chloride, sulfates, PH and EC using standard techniques in the laboratory. Also, geographic information system-based groundwater quality mapping in the form of visually communicating contour maps was developed using ArcGISversion 10.2 software to delineate spatial distribution in physicochemical characteristics of groundwater samples. the result showed that all samples concentration for TSS and Sulfates are well over the Standard recommended by WHO . and Cl is below WHO Besides thematic maps of these mentioned quality parameters showed a strong prediction and water suitable for using in concrete mixture. From ground water properties we can note the type and quantity of cement for each one cubic meter use in foundation of new structures.
