This review article presents a brief definition of clean drinking water. The concentration of fecal coliforms is used as an indicator of level of water pollution.

Cisterns which were fed by water originating from streets had more than 100 fecal coliforms/100 ml. Cisterns which were fed by water from home yards had the least level of coliform pollution. Cisterns which are located at a distance of more than 50 meters from sewage soakage pits had 50% less pollution than cisterns which are located at a shorter distance from soakage pits. The use of electric pumps in cisterns significantly reduced the pollution levels of the cisterns. Piped network water that is chemically treated had no significant pollution. Spring water showed seasonal fluctuations in pollution levels. All open water canals had more than 200 fecal coliforms/100 ml of water.
