Drinking water of these rural areas have provided of deep, semi-deep wells and spring water sources. Because of the both sources were used in the rural areas and also due to use of different storage sources (new and old sources), we collected 359 samples during a month period to test for microbial quality.

Results show that residual chlorine content in drinking water in 33.88 percent of rural areas population was in range 0.2-1 mg/l. In 98.3 percent of the Saqqez rural areas the turbidity level was less than Iranian maximum permissible levels (5 NTU).
