Abstract: Ground water quality of Najran region was studied in 43 well water samples collected from different wells in the region. Water samples were chemically analyzed and evaluated using water quality criteria. Also, about 48.8% of the water had salinity above the recommended level for drinking water. These results indicated no expected problems with either sodium or permeability from most of the studied wells. Also, it was found that in Najran region a large fraction of farms ( more than 35%) which have been equipped with tube wells and irrigation systems have abandoned business and farming as a result of groundwater depletion, this is because the annual groundwater discharge far exceeds the precharge. The excessive extraction of groundwater resources have caused that water for human consumption and agriculture has become an increasingly scarce, which resulted with detrimental effects on the environment by desertification and climate change, especially in Saudi Arabia experiencing drought and hot and dry climate.
