摘要
历史上淄河下游的人畜供水一直依赖地下水，但20世纪80年代以来区内淄河下游河道长期接纳上游污水，地表水和浅层地下水受到污染，浅层地下水已不适于人畜饮用。污染区沿淄河呈条带状展布，污染区边界距淄河约1.0～1．5km，其中距淄河500m以内的区域污染最为严重。中深层地下水水质良好，仅个别井点因井管损坏造成点状串层污染，可做为人畜用水水源。基本可满足2010年前区内人畜供水要求。人畜供水开采中深层地下水时，应根据地下水污染特征和中深层含水层水文地质特征，分区分层开采，实现地下水合理开发，防止中深层地下水串层污染，保护宝贵的地下水资源。
In the polluted area of the downstream of Zihe River,water supply for human and livestock depend on groundwater. Since 1980s,the watercourse has accepted the polluted water from the upriver, the surface water and shallow ground water have been polluted, and the middle and deep groundwater appeared pollution too last years. The polluted belt distributes along the Zihe River with width about 1.0 - 1.5 km,and the most serious polluted belt is within 500 meters from the banks. The shallow groundwater is not suitable for drinking in the belt. The middle and deep groundwater quality is better and can be used for living,except for a few wells polluted slightly by the tube damage resulting in the aquifers mixing up. The quality and the quantity of the middle and deep groundwater are enough for the need of the water supply until 2010 locally. We＇d better exploit the groundwater in different layers based on the characters of the polluted water and hydrogeology characters of the middle and deep aquifers in order to prevent the pollution caused by the aquifers mixing, and protect the valuable groundwater resource.
