chemical and physical analysis of some ground water sample in al-quti wells hodiedah, yemen

study of the ground water quality in hodeidah is an essential ingredient for a healthypopulation. in this research, study of drinking water samples for eight water sources wells in thequti field has been achieved. the purpose was to a certain the quality of water from thesesources, the physical properties such as ph, electrical conductivity (ec) and total dissolvedsolids (tds), showed the variation of ph (7.24-7.80),tds (744.0-1008.6) mg l-1, within thepermissible limits for world health organization (who). except well(1) which had slightexcess for tds (100.8 mg l-1). the measurements of total hardness (th) , no3-,so42-, po43-, cl-, na+, k+, ca2+ and mg2+ has been measured. the levels of no3 were unacceptable by the valueof (70-153) mg l-1. and so42- by the range of (130-420) mg l-1, recalls exceeding the allowablevalues given by who, while cl-, na+ , ca2+ ,th, total alkalinity and mg2+ were the permissiblelimits for who and yemen standard (ys). the analysis data of heavy elements concentrationcr, fe, and mn were far from the pollution and within the permissible limits.
