江西省九江市规划区地下水特征及其环境评价

Jiangxi Province Jiujiang city plan area ground water characteristic and its environment appraisal

在分析介绍九江地区地下水类型(松散岩类孔隙水、碳酸盐岩裂隙岩溶水、基岩裂隙水)和地下水环境条件及其动态变化规律的基础上,采用《生活饮用水卫生标准》,对研究区地下水环境,包括地下水质量和地下水污染现状进行了评价。研究区内合格的地下水占56%,不合格的占12%,中等不合格占16%,严重不合格占16%。地下水污染形成了4个严重污染区块,全区未污染地下水仅占8%、轻微污染占36%、中等污染占20%、严重污染占36%。污染项目主要为PH、氨氮、硝酸盐、亚硝酸盐、氛等指标。由此提出了保护地下水资源的建议。

This article has introduced the Jiujiang area ground water type （loosecrag class pore water, carbonate rocks crevasse karst water, hedrockcrevice water） , the ground water environmental condition and its study dynamic changing rules to use ＂Life Tap water HealthStandard＂ to study the area ground water environment, and to carry on the appraisal including the ground water quality and the groundwater pollution situation. It pointed out the qualified ground water accounts for 56% in the research area, unqualified accounts for 12%, medium not qualified accountsfor 16% , serious non-qualified accounts for 16%. The ground water pollution has formed 4 serious pollution sub - areas, the entire area has not been polluted only to account for 8%, the slight pollution accounts for 36%, the medium pollution accounts for 20%, the serious pollution accounts for 36%. The pollution project mainly is PH, ammonia nitrogen, nitrate, nitrite, atmosphere and so on. Finally,it also puts forward proposal to protect ground water resources.
