A total of 106 seasonal water samples collected from 16 representative sites in and around Ben ghazi city between January 1982 and November 1984 were subjected to physicochemical and bacteriological analyses. Along with total alkalinity, solid contents, hardness and conductivity among 7 intrinsic properties, the study compared the seasonal and biannual variations of 11 macroconstituents, 13 trace elements, and the bacterial flora in each specimen. A total of 26 species representing 17 bacterial genera were isolated and identified; Esch. coli was recovered from only 3 of the samples examined, indicating the relatively rare contamination of drinking waters by sewage. However, the hardness, electrical conductivity and solid content values ascertained indicated significant accumulation of chlorides, sodium and sulfates; that increases or continuously raised amounts of these and other pertinent ions was observed and may pose health hazards in particular age groups or specific pathological states, is discussed.
