GFW4 and 5 are locate in semi confined Dammam formation and deeper then GFW1, 2 and 3 which located in unconfined Dibdiba. Eleven parameters as: pH, electrical conductivity; EC, total dissolved solids; TDS, sulfate ion; SO4-2, oil & grease; O&G, cadmium; Cd, lead; Pb, chromium; Cr, iron; Fe, copper; Cu, and zinc; Zn have been selected to determine water quality index (WQI) for irrigation and potable purposes according to maximum levels of standards
