[摘要]目的了解四平市区无负压供水的卫生状况，探讨分析卫生监管中存在问题，为有效监管提供科学依据，保障群众饮用水卫生安全。方法对四平市区无负压供水卫生现状进行调查，并随机抽取19个居民小区无负压供水泵站，每个泵站分别采集供水管网末梢水2份，每份水样检测指标为8项，按照《生活饮用水卫生标准》（GB5749-2006）判定水质情况。结果经调查四平市区共有无负压供水泵站178处，其中市政供水公司管理泵站122处、居民小区物业或单位管理泵站56处，卫生管理合格率为66.3%。抽检的38份水样中合格36份，合格率为94.7%。结论四平市区无负压供水存在安全隐患，建议国家、省、市尽快出台无负压供水监管相关法律、法规及规范，卫生监督部门加强对无负压供水单位的监督管理，保障群众饮用水卫生安全。
