Abstract: The water quality has more importance for farming, especially in arid and semi-arid regions and limited water resources areas such as Saudi Arabia. The present study is focus on the quality of well water spreading in the Tihama plains. The study area located in the southern part of Tihama plains which lies between longitudes 42˚ 46' 13.6" E and 43˚ 05' 42.4"E and latitudes 16˚ 24' 24.2" N and 16˚ 36' 25.8" N. About 47 groundwater samples collected in plastic bottles from different wells in the study area for chemical analysis. The electrical conductivity (EC), pH, cations, anions, boron and nitrate were determined for each sample using the recommended methods. The results showed that collected samples differed in chemical characterization. The dominant cations were Na+(49.8%)> Ca2+(28.93%)> Mg2+(20.83%). Also, the dominant anions were Cl-(66.13%) > SO4= (25.42%) > HCO3-(8.45%). About 49% of samples have salinity level over 3 dS/m , while 76.6% of samples have salinity level over 2.25 dS/m(class C4 according to the USSL).The SAR values were in suitable range(for 94% of samples) . Boron and nitrate levels were in the allowable range.
