关于饮用地下水水质评价标准的探讨——以华北平原地下水水质调查结果为例

地下水水质评价方法应以人体健康为依据,同时满足原理简单、计算简便、物理意义明确三个特点.基于地下水水质标准GB/T14848-93,修订了其分级限值,使得评价结果的物理意义更为明确.本文根据华北平原地下水水质测试结果评价了水质状况,对水中主要有机和无机组分在区域上的分布特征及可能来源进行了分析.为了使地下水水质评价的结果更加适合我国的国情,提出了地下水饮用适宜性评价意见,并对评价结果进行了讨论.

A Tentative Discussion on the Assessment Standards of Groundwater Quality: A Case Study of the Groundwater Quality in the North China Plain

Groundwater quality should be assessed according to the requirement of human health. The assessment method should be simple and easily understood. Based on the groundwater assessment method (GB /T14848-93), the authors revised the water quality classification criteria, which makes the assessment results consistent to the requirement of drinking water quality. Exemplified by the groundwater analyzing results from the North China Plain, the authors also assessed the water quality and probed into the possible origin of the main compounds. As different regions of China had quite different situations, the water chemical conditions were discussed in terms of a new concept, i.e., suitability of water for drinking, which was put forward for the first time in this study.
