| Abstract: | Objective To Cenderstand the sanitation status of secondary drinking water supply system of public places. Methoods The sanitation of secondary drinking water supply system was investigated by on_site survey method and the sanitary quality of water samples were determined. Results The over_standard rates contents of Fe and total coliformz of water samples of secondary water supply system significantly increased compared with the related levels of tap water of municipal water supply. The unqualified rate of free residual chorine of water sample from secondary water supply system reached 54.55%. Conclusions The equipments for secondary water supply were obsolete and unretional design. The sanitary quality of secondary water supply was also affected by geological structure easily. |
