Dampare Received: 12 November 2017 / Accepted: 18 May 2018 © Springer Science+Business Media B.V., part of Springer Nature 2018 Abstract The Lower Volta River Basin of Ghana is an important international and local tourism destination. Communities in the basin depend on shallow aquifer systems, the Volta River, and nearby streams as their sources of water for domestic purposes, cattle watering, and irrigation. Due to increasing human activities and limited information on water quality in the area, a holistic assessment of the quality of the water resources in the 2 18 basin was conducted using hydrochemistry, δ H and δ O, principal components analy- sis, and selected indices. EC ranged from 141 to 19,370 μS/cm and 60.9–986 μS/cm for shallow groundwater and surface water respectively. NO levels above 45–1049.9 mg/l were observed in 45% of analyzed wells. Na–Cl- and HC O –Ca-dominant facies are identi- fied. Silicate weathering, evaporite dissolution, cation exchange, and salinity are the hydro - 2 18 chemical processes influencing the shallow groundwater in
