Variation of groundwater depth and cation concentrations with CBRs of residual soils: Case study of three lithologic terrains from North-central Nigeria
TAS Ugwoke, SHD Waziri - Journal of African Earth Sciences, 2020 - Elsevier
Twenty nine (29) water samples and 24 soil samples were collected from three lithologic
terrains. The waters were subjected to Atomic Absorption Spectrophotometer (AAS). The
soils were subjected to California Bearing Ratio (CBR) tests. The AAS revealed that water
from gneiss/schist terrain have mean Ca 2+, Na+, Mg 2+ and K+ concentrations of 25.09,
13.14, 10.92 and 3.90 mg/l respectively; water from granite terrain have mean Ca 2+, Na+,
Mg 2+ and K+ concentrations of 13.68, 6.39, 5.45 and 2.78 mg/l respectively while water …
