The assessment result shows: the infirm zone of the aquifer basically distributes in the limestone area of low Ordovician -top Cambrian, which the cranny is uncovered and overgrown, the area is also the direct recharge area of spring basin. In addition , in the rivers valley area of Jin xiuchuan and Bei sha river, because the leakage of the river is serious, the contamination can leak easily to the groundwater in the area of surface and near the river, so this area also is the infirm zone. Frail zone distributes in the uncovered area of mid-Cambrian which the canny upgrowth is commonly, parts of the zone distributes the relatively impervious layer such as shale. In the north-west area where is the down-rivers of two rivers, the alluvium is thick, the protection to the limestone is good.

评价结果显示，济南岩溶泉域含水层很脆弱区基本分布在济南泉域的岩溶裂隙非常发育的、裸露的下奥陶～上寒武的石灰岩地区，该地区也是泉域的直接补给区，另外在锦绣川、北沙河等河谷地带，由于河床渗漏严重，地表水及近河地带污染物容易渗入地下，也为很脆弱区；脆弱区一般分布在裸露的中寒武地层区，岩溶裂隙发育一般，部分地带分布有页岩等相对隔水层；西北部两河下游冲积层较厚，对下伏石灰岩保护功能较强，属于脆弱性相对很低区。
