PHYSICOCHEMICAL AND HEAVY METAL ANALYSES OF DRINKING WATER IN OGWA AND EBELLE AREA OF EDO STATE, NIGERIA (original) (raw)

2020, Journal of Laboratory Science

Water samples obtained from selected underground reservoirs and boreholes in Edo state, Nigeria were analysed for heavy metal concentration using flame photometer and Atomic Absorption Spectrophotometer. The result of physicochemical parameters obtained from the borehole water, fell within the maximum allowable limit set by WHO and Nigeria standards for drinking water but the concentration of Cu (0.15 ppm), Ca (0.15 ppm), Mn (0.29 ppm), and Fe (0.16 ppm) in Eguare 2, Mn (0.12 ppm) in Okalo and Fe (0.49 ppm) in Okpujie exceeded WHO standards for drinking water. The result also shows that borehole waters in these communities were safer for drinking than underground reservoirs. This was because most of the heavy metals were found in greater concentration in the underground reservoir exceeding national and international standards of drinking water quality. The study recommends that Government should make arrangements for continuous inspection of water schemes, health and functionality to avoid the danger of drinking untreated water.
