Groundwater residence time in basement aquifers of the Ochi-Narkwa Basin in the Central Region of Ghana

Original language description

Groundwaters from basement aquifers in the Ochi - Narkwa basin of the Central Region together with rain and surface waters have been analysed for stable isotopes (delta O - 18, delta H - 2 and delta C - 13) and radioisotopes (H - 3 and C - 14) to determine sources of recharge, groundwater residence time and flow path. The mechanism of recharge to the groundwaters is by direct infiltration of past local rainfall of mean isotopic composition delta O - 18 = - 3,8 parts per thousand V - SMOW and delta H - 2 = -18 parts per thousand V - SMOW. Tritium in the groundwaters ranged from 0,05 +/- 0,07 to 4,75 +/- 0,16 TU. Tritium data revealed that 85% of the groundwater samples were of modern recharge or young waters. The C - 14 content of the groundwaters ranged between 9,50 pMC in borehole CR2 - 50 at Ekumfi Asokwa to 113,56 pMC in borehole CR3 - 26 at Onyaadze. Evaluation of H - 3 and C - 14 data distinguished three groups of water namely (1) waters characterised by high H - 3 and high C - 14 depicting mode
