This paper evaluates the influence of rock chemistry on groundwater quality in the region of Lodwar County, Kenya. Rock geochemistry influences groundwater quality and the aquifer processes of an area. Therefore, this study used conventional petrography and geochemistry techniques to measure the mineralogical compositions of 69 rock samples. The geological study area comprised of quartzo-feldspathic gneiss and biotite gneiss of the Precambrian basement, as well as sedimentary Turkana Grits and Holocene sediments, Tertiary volcanics comprising nepheline phonolites and augite basalts, alluvial deposits along the banks of major Streams and laggas. Quaternary sands also blanket much of the area. The results demonstrate that that geological factors and processes have location-specific influence on groundwater quality. These should be considered in aquifer water-quality studies and supply development across Africa’s vast ASAL regions.
