为全面了解东台市深层地下水水源卫生状况.从1995年起对东台市沿海地区深层地下水开展了监督监测工作.现将水质卫生状况分析加下:东台市卫生防疫站专业人员按统一印制调查表填写,在现场对成井的时间、深度、结构、防护情况、供水范围、日均供水量及使用年限等基本情况进行调查.建立卫生档案.从1995年2季度开始.1997年3季度结束,分别在枯水期、丰水期对堤东沿海地区22个乡镇农村的318眼新老水井水质进行采样监测两次.共分析感官性状及化学指标12项(色度、浊度、臭和味、肉眼可见物.pH值、总硬度、铁、锰、铜、锌、氯化物、溶解性总固体),毒理学指标6项(氟化物、砷、铅、汞、氨氮、硝酸盐氮),细菌学指标两项(细菌总数、大肠菌群).监测方法按《生活饮用水标准检验方法》进行.以《生活饮用水卫生标准》(GB5749—85)为依据.对水质监测结果进行统计分析.
In order to fully understand the health status of deep groundwater in Dongtai City, monitoring and monitoring work has been carried out on the deep groundwater in the coastal area of Dongtai since 1995. Now add the following to the analysis of water quality and sanitation status: professionals in Dongtai Health and Anti-epidemic Station press the unified printed questionnaire Fill in and investigate the basic conditions such as the time, depth, structure, protection, water supply range, average daily water supply and service life of the well that is going to be completed at the site, and set up the health archives from the second quarter of 1995. The end of the third quarter of 1997 respectively During the dry season and wet season, the water quality of 318 old and new wells in 22 towns and villages in the coastal area of Tiandong was sampled and monitored twice, and 12 items of sensory traits and chemical indexes were analyzed (color, turbidity, odor and taste, PH, total hardness, iron, manganese, copper, zinc, chloride, total dissolved solids), 6 toxicological indicators (fluoride, arsenic, lead, mercury, ammonia nitrogen, nitrate nitrogen) Two (total number of bacteria, coliform bacteria) .Method of monitoring according to “drinking water standard test method.” To “drinking water health standards” (GB5749-85) as the basis for water quality monitoring results Analysis.
