摘要

[Objective] Grasp quality and health status of drinking water,and provide scientific basis for decision making of health administrative department. [Method]According to the Standards for Drinking Water Quality( GB 5749- 2006),monitoring results of Tianjin urban and rural drinking water health in 2013 were evaluated,and software SPSS 20. 0 and GeoD a was used for temporal-spatial analysis on water quality. [Result]There were 2 882 copies of monitoring samples in total,in which both finished water and tap water of urban district were qualified,while qualified rates of tap water and secondary water supply from the county were respectively 86. 36% and 93. 91%,and major exceeding indexes were pH and total number of colonies. Qualified rates of tap water and secondary water supply from the county had difference( χ2= 1 576. 875,P < 0. 01). Quality of tap water( χ2= 5. 425,P > 0. 05) and secondary water supply( χ2= 16. 009,P > 0. 05) was stable at temporal distribution( January-December),but spatial distribution of tap water had certain regional difference( χ2= 1 255. 802,P < 0. 01). [Conclusion] General quality situation of Tianjin urban and rural drinking water was better,but qualified rate of water quality in some counties was lower,which had safety risk and threatened the health of residents in the corresponding county. The related departments should enhance the supervision and management of drinking water supply,improve supply water quality,strengthen water quality monitoring,and guarantee drinking water safety. Geographic information system can better realize visualization of drinking water quality monitoring information.
