一、案情与问题2006年9月8日,湖南省岳阳县发生自来水水源受到砷化合物污染事件,饮用水源砷含量超标10倍,影响到10万人的饮用水。事故发生后,岳阳县于9月8日深夜启动应急供水方案,开启县城地下水源,日供1500吨清洁饮用水,同时动员县直属行政、事业单位自备车辆和取水工具,到20公里外的岳阳市区取水点运水。另一方面,从市、县调集18辆消防车、洒水车从岳阳市紧急运送饮用水,并组织数百名党员干部给城关各社区、学校、医院、看守所、特困企业送水,以确保他们生活、生产正常进行。9月9日凌晨1时49分,铁山水库开闸放水。岳阳县自来水污染应急处理指挥部紧急通知沿河公田、杨林、麻塘、城关等8个乡镇做好河道疏浚、安全检查工作,县水利部门加强力量沿河巡逻督导。9日下午,岳阳市又下令新墙河上游忠防水库开闸放水。两个水库开闸放水,流向新墙河,稀释了河水中的污染物,加快了污水团下泄流速。据悉,这是最近几年湖南乃至全国罕见的环保危机个案。这次砷化合物污染尚未发现有人出现中毒症状,但长期饮用这种受污染的水,则会造成中毒。
