Abstract

The general chemistry of Saudi Ground water is introduced by way of chemical analysis and parameters such as pH, electrical conductivity (E.C.), total dissolved solids (T.O.S.), and major cations and anions which are of significance to water quality. The frequency distribution of E.C. and T.O.S. in a random group water sample (n=530) with respect to water quality is presented. A new association between E.C. and T.O.S. for Saudi ground water is proposed with a modified formula: T.O.S. = (E.C. x 850) -200, which is subjected to further modification according to each regional ground water characteristics. Range and variation of individual major cations and anions are summarized for comparison via the utilization of RA WRC Water Bank samples which were collected according to E.C. range from 0.8 to 9.0 for the years 1981 and 1982.
