摘　　要：江苏涟水县深层地下水水质较好,能达到饮用天然矿泉水的水质要求,摸清涟水县矿泉水资源分布及水质特征,对区域矿泉水开发利用具有重要作用。通过对涟水县深井水进行水样采集和测试分析,探索矿泉水赋存水文地质条件及水质特征,结果显示:研究区深层地下水感观特征、界限指标和污染物指标均符合规范要求。其中界限指标偏硅酸(H2SiO3)含量37.90~76.15 mg/L,锶(Sr)含量0.406~0.81 mg/L,含量较稳定,均达到国家饮用天然矿泉水标准,属于偏硅酸-锶型饮用天然矿泉水。矿泉水分布于涟水县全境,主要赋存于第Ⅲ、Ⅳ承压含水层,水量较丰富,具有广阔的开发利用前景。Jiangsu lianshui county deep groundwater quality is good,can meet the requirements for quality of the drinking natural mineral water clear lianshui county water resources distribution and water quality characteristics,plays an important role in the development and utilization of regional mineral water by water samples and test analysis was carried out on the lianshui county deep well water,explore mineral occurrence of hydrogeological conditions and water quality characteristics,the result shows: the deep sensory characteristics of groundwater in the study area boundary indicators and pollutants are conform to the requirements of the specificationAmong them,the limit index,the content of metasilicic acid( H2SiO3),is 37. 90 ~76. 15 mg/L,and the content of strontium( Sr) is 0. 406 ~ 0. 81 mg/L,which are stable and meet the national standard for drinking natural mineral water. It belongs to the type of metasilicic acid and strontium-type natural mineral water,which is distributed throughout lianshui county and mainly occurs in Ⅲ and IV confined aquifer. It is rich in water and has broad prospects for development and utilization.
