ABSTRACT
Objective To evaluate the running status of the water-improving projects in Gansu Province in order to further improve the supervising mechanism and raise the efficiency of defluoridation in drinking water.Methods The water-improving projects,either being normal,or intermittent,or discarded and the cause of abnormal running in 33 counties in Gansu Province were surveyed with unified standard method.Fluoride content in water was determined by F-ion selective electrode.Results 993 water improving projects covering 3389 fluorosis villages were surveyed,682 projects worked well[68.68%(682/993)]and had supplied water with normal fluoride contents to 2174 villages[64.15%(2174/3389)]and benefited 116.56 hundred thousand populations.And the rest 311[31.32%(311/993)]projects worked abnormally or supplied unqualified fluoride water.The main causes were the exceeded lasting life,insufficiency of water resources,high fluoride content in water and unqualified administration.Conclusions Most of the water-improving projects in Gansu Province are basically running normally,but about 1/3 of the projects do not function well,so the management of the projects must be improved and consummated.
