| 摘 要： | 目的:了解该地区深层地下水质变化情况。方法:对1995年和2010年丰水期水质调查资料,按照GB/T14848-93《地下水质量标准》分别进行统计、分析和比较。结果:1995年该地区地下水质符合"优良"(Ⅰ类)一级水源(F<0.80),到2010年水质变为"较好"(Ⅰ类)三级水源(F>2.50)。结论:15年来该地区地下水污染严重,污染源主要是农业化肥和人畜排泄物,污染途径主要是废弃的深井和雨水渗透,预测到2020年后,该地区地下水将不可以作为直接集中式生活饮用水供水水源。

| Abstract: | Objective:To understand the changes of deep underground water quality in the region.Methods: Water quality data in high flow period of1995 and 2010 were analyzed and compared according to the GB/T14848-93 "Quality standard for groundwater".Results: In 1995,groundwater in this area was classified as first-grade water resource in Class Ⅰ,(F<0.80),while in 2010,it had downgraded to the third-grade in ClassⅠ,(F>2.50).Conclusion: The groundwater in Jianhu county was heavily polluted in the past 15 years.The pollution sources were agricultural fertilizers as well as human and animal waste.Abandoned deep wells and rainwater infiltration were the main pollution ways.It was predicted that the groundwater in this area would not be the direct centralized drinking water supply in 2020. |
