A Comparative Analysis of Chemical Quality of Weathered Regolith and Hard Rock Groundwater Environments in Ibadan, Nigeria
Adesola Adediran,
Abstract:
In the Ibadan area of Nigeria, the physico-chemical quality of groundwater was compared
between the weathered overburden and hard rock environment, 30 samples of wells and
boreholes were surveyed between July 2011 and August 2011. Water samples were
analyzed for pH, TDS, Alkalinity, Hardness, Calcium and Magnesium. The results show
variations in wells given as PH (5.8-7.0), TDS (99-356), Alkalinity (0.55-2.20), Hardness
(2.90-10.35), and Calcium (2.10-9.30), however, variations in boreholes were PH (6.20-
7.10), TDS (109-310), Alkalinity (0.85-2.20), Hardness (3.05-12.35), Calcium (2.10-
12.20), Magnesium (0.30-2.35). The result showed that there is an influence of
environment on the quality of groundwater because the parameters of boreholes showed
that they had acceptable quality in consumption and domestic uses.
