Includes references.

Hundred twenty six ground Water samples from fourty two wells comprising different depths. Ten wells at less than 15 m. depth; twelve deeper wells between 15 and 30m. depth: and deepest wells more than 30 m. depth. These wells were found at various localities in Giza and Kaluobia governorates. These wells were examined chemically and bacteriologically. From the obtained data, it was found that the observed values or concentrations of cadmium, nitrate and phosphate above the maximum desirable limits specified by world Health organization (WHO) for use as drinking in 35.71.33.33 and 26.19 % of totally examined wells respectively. Whereas, fecal coliform. Streptococcus faecalis, chloride and copper polluted wells were found to be at a percentage 16.66, 7.14, 4.76 and 4.76%. However, the pollution with ammonia, sulphate, irons and lead was found to be within the permissible limits. The shallow wells (up to 15m.depth) were examined. The percentage of polluted Wells was found to be highest with cadmium, then phosphate, faecal coliform, copper and streptococcus faecalis at a Percentage of 60, 50,50. 20 and 20% respectively.
