摘要
在分析研究区水文地质条件的基础上,采用单因子指数法对广东某发电厂建设场地地下水环境质量现状进行评价.结果表明:地下水环境质量总体较好,但局部地区存在亚硝酸盐、COD、矿物油等指标超标现象.地下水亚硝酸盐严重超标区域主要分布在部分谷地低洼地段,这些低洼地段大多是地下水排泄区和农业生产活动集中区域.在水文地质条件和农业面源污染的共同作用下,这些低洼地段地下水亚硝酸盐逐渐富集.本研究可以为地下水环境影响评价和水资源科学管理提供科学依据.
Abstract
Based on analysis of the hydro-geological conditions in the study area,groundwater environmental quality in the construction site of Guangdong power plant was evaluated using single-factor index method.Results showed that the over-all quality of groundwater environment was good,but there were some indexes such as nitrite,COD and mineral oil exceeding standard in local areas.The nitrite in groundwater that exceeded the quality standard mainly occurred in low-lying areas in some valleys,and these low-lying areas are mostly groundwater discharge areas and agricultural production regions.The ni-trite in groundwater in these low-lying areas was gradually enriched,with the combined effects of hydrogeological conditions and non-point source pollution from agriculture.This study can provide scientific basis for groundwater environmental impact assessment and water resources scientific management.
