石家庄市东部深层地下天然饮用矿泉水田评价

Appraisement of Deep Potable Natural Mineral Water Field in the East of Shijiazhuang City

通过调查发现,石家庄城市东部深层地下赋存有优质天然矿泉水资源。由深层地下水流场图、深层地下水水化学及锶偏硅酸含量分布图和深层地下水含水层分布情况来综合确定石家庄市矿泉水田范围,初步圈定了3处饮用天然矿泉水田。计算饮用天然矿泉水田储存量为0.75×108m3;经评价,矿泉水田地下水感官要求、理化要求(包括界限指标、限量指标、污染物指标、微生物指标)符合《饮用天然矿泉水》(GB8537-2008)的要求,其中界限指标锶全部符合,偏硅酸部分符合,矿泉水田分别属锶型或锶、偏硅酸型饮用天然矿泉水。

There is super quality potable natural mineral water resource in the deep stratum in the east of Shijiazhuang city. According to the map of the deep groundwater flow field, the deep groundwater chemistry, strontium and metasilicate content distribution and deep exiting water strata bound distributing, the potable nature mineral water field area are determined and the three potable natural mineral water fields are delineated at first. The potable natural mineral water reserve is 1.208×108 m3. The groundwater sense demand and the physicochemical standard （including bound index, limited index, contamination index and microorganism index） accord with the standard of ＂drinking potable natural mineral water＂（GB8537-2008）, only the Sr and metasilicate bound index is part accorded with the standard. The mineral water field belongs to Sr or Sr-strontium metasilicate drinking potable natural mineral water.
