河北保定市区现有3个城市集中式饮用水水源地,分别是一亩泉地下水水源地、西大洋水库地表水水源地、王快水库地表水水源地。随着城市居民对饮水安全要求的提高,水源地供水水质就显得尤为重要,通过对城区三处水源地2017年水质监测资料进行整编分析,评价水源地污染现状并提出改进措施,结果可知:市区3个城市集中式饮用水水源地水质状况均满足城市供水要求。但应进一步加强库区水资源保护,改善库区的水环境质量,保护好地表水资源。 相似文献

Calcite samples were extracted both from the rock matrix and the superficial coating of a karstified fault plane of an underground quarry, located in the eastern border of the Paris basin. The karstification is dated as Quaternary. Analysis of mechanical calcite twinning reveals that only the calcite matrix has also undergone a compression trending WNW that can be attributed to the Mio-Pliocene alpine collision. Both coating and matrix have undergone a strike-slip regime with σ1 roughly trending north–south, that could correspond to the regional present-day state of stress, a strike-slip compression rather trending NNW, modified by local phenomena.
