Abstract: This research study focuses on hydro-geochemistry of Chanchaga area which forms an integral part of Minna North Central, Nigeria. The area is underlain by the Precambrian Basement Complex crystalline rocks such as Schist, Migmatite Gneiss and Granites. These rocks are dominantly structured in NE – SW and N – S directions. These structures have effect on both surface drainage pattern and influence the groundwater and surface water flow directions in the area.
