The scientists studied groundwater in Ndokwa, Nigeria using geological and geophysical surveys. They found multiple layers of sandstone and clay in the ground, with the average depth to the water source being around 72 meters. The water-bearing layer is about 42 meters thick, with a resistivity value of 1289 Ωm. The area's aquifer has a transmissivity of 1162.31 m2/day and a hydraulic conductivity of 27.28 m/day. The overlying soil is not very protective, making the aquifer vulnerable to contamination. The study also showed that different parts of the area have varying levels of vulnerability to pollution. The topsoil in the region is mostly non-corrosive. These findings are important for managing and developing groundwater resources in Ndokwa.
