摘 要：Groundwater studies were carried out between two geological groups to evaluate factors that influences groundwater *** achieve this,30 groundwater samples were *** such as pH,Electrical Conductivity(Ec),Total Dissolved Solids(TDS),Total Hardness(TH),and hydrochemical characteristics(Na^(2+),K^(+),Ca^(2+),Mg^(2+),HCO_(3)^(¯),NO_(3)^(¯),Cl^(¯),CO_(2)^(3¯),and SO_(4)^(2¯))of groundwater were *** revealed that the pH value for Asu River Group ranges from 5.3 to 7.5,and that of Eze Aku Group ranges from 4.1 to *** was observed that areas around the mines had low pH *** results that were obtained were interpreted using various hydrogeochemical *** plots reflected that groundwater within the two geological groups fell within Ca˗Mg˗SO_(4) and Ca˗Mg˗*** from End˗member plots showed that 96%of groundwater samples analyzed were categorized under carbonate weathering,4%fell silicate *** plots revealed that interactions between groundwater and surrounding host rocks are mostly the main processes responsible for chemical characteristics of groundwater,Diamond field plots suggested that groundwater within the study were categorized to be high in Ca+Mg&SO_(4)+Cl,the plot of Ca^(2+)/(HCO_(3)^(¯)+SO_(4)^(2¯))against Na^(+)/Cl^(¯)revealed that groundwater was considered to be within the natural state for the two *** plot of TDS against TH showed that groundwater is classified as soft *** study revealed there was no significant difference between factors that influence groundwater within the two geological.
