and open wells

chemicals and microorganisms are common in human environments and at high levels
poisoning from the chronic effects have occasionally occurred. The purpose of
this study was therefore to investigate whether the levels of inorganic
chemicals and microbial contaminants in boreholes and open wells in selected
Districts in Benin City are sufficient to affect the health of the inhabitants
of the areas under investigation.
Six (6) boreholes and three
(3) open wells were randomly selected from two Districts (Okhoro and Teboga) in
Benin City. Water samples were collected from the boreholes and open wells using
standard techniques. Lead (Pb), chromium (Cr), zinc (Zn), and cadmium (Cd)
concentrations as well as aerobic bacteria, presumptive faecal coliform, E. coli,
faecal Streptococci and fungi in the water samples were determined using
standard procedures. World Health Organisation acceptable limits for drinking
water were used in the evaluation.
All the boreholes and open
wells were contaminated with abnormal levels of Pb. High levels of Cr and Cd
were found in the borehole and open wells at Okhoro. Abnormal levels of Zn
concentrations were detected in almost all the boreholes and open wells. All the
boreholes at Teboga were contaminated with unacceptable levels of aerobic
bacteria and fungi. Presumptive faecal colifom, E.coli and faecal Streptococci
were seen in all the boreholes.
Some boreholes and open
wells in Okhoro and Teboga Districts in Benin City are contaminated with
abnormal levels of metals and microorganisms capable of causing health hazards
to the consumers of boreholes and open wells.
