地下水环境影响一级评价水文地质调查的工作内容和方法

自《环境影响评价技术导则一地下水环境》实施以来，地下水环境影响评价就成为整个建设项目环境影响评价中的难点。本文以对水文地质调查的调查精度要求最高的一级评价为例，从资料收集、野外调查、室内模拟和污染预测几个方面论述一级评价水文地质调查的内容和方法，总结了在此过程中需要注意的几个问题，为广大的水体环境影响评价工作者提供参考。

Hydrogeology survey work content and method of the one-level environmental impact assessment of groundwater

The environmental impact assessment of groundwater has become a difficulty since the implementation 《technical guidelines for environmental impact assessment-groundwater environment》 . This paper held out a firstclass assessment example. It demanded the highest precision of hydrogeological survey accuracy among three classes assessment. This paper summarized hydrogeological investigation contents and methods of first-class assessment including data collection, field survey, indoor simulation and pollution prediction. Moreover, several points were summarized,which provided reference to the environmental impact assessment of groundwater.
