Physicochemical Parameters of Ground Water Quality in Crown Estate and Its Environs in Okada Town, Edo State, Nigeria

Abstract

The evaluation of drinking water quality mainly by determination of some physicochemical parameters present is of paramount importance due to the impact on human health. The present study presents investigation on the physicochemical parameters of ground water samples collected from selected boreholes, in Crown Estate and environs, in Okada, Benin City, Nigeria. Samples were collected from selected boreholes and pH taken and immediately taken to the laboratory to investigate some selected physicochemical characteristics. The mean concentrations of metals in the water samples followed a decreasing order: Zn (0.5122mg/l) > Fe (0.4378mg/l) > Mn (0.0594mg/l) > Ni (0.0358mg/l) > Cr (0.0302mg/l) > Cu (0.3000mg/l), Pb and Cd were below detection limit. The laboratory results of all the selected physico-chemical parameters analyzed when compared with the world health organization (WHO), National Agency for Food and Drug Administration Control (NAFDAC) and Nigerian Standards for Drinking Water Quality (NSDWQ) standards for water showed that all the selected Physicochemical parameters with the exception of iron (for NAFDAC) were within national and international standards limits for drinking water.
