黄河下游河南段浅层地下水质量评价及污染分析

Analysis on Evaluation and Pollution of Groundwater Quality in the Shallow Aquifer of Henan Section in the Lower reaches of Huang River

黄河下游冲积平原(河南段)浅层地下水资源丰富,浅层地下水质量如何?以水质监测资料为依据,根据地下水质量标准和饮用水标准进行了水质评价。结果表明,河南段浅层地下水作为饮用水使用,水质多属好、较好水,少部分属差、较差水,地下水质量多为较好的Ⅲ级水,没有极差的Ⅴ级水存在,矿化度及地下水类型分布总体特征是:从西到东水质由好到差,矿化度由低到高,地下水类型由简单(HCO—Ca、Mg)到复杂HCO、CI—Na、Mg、Ca的变化特征。

The alluvial plain（Henan Section） in the lower reaches of Huang River has rich in water resources. How is the water quality in the shallow aquifer. The article is based on the monitored data of water quality, the water quality is evaluated according to standard of groundwater quality and drinking water. The result shows the groundwater in the Henan section can be used as the drinking water.
