“…Erah et al . [35] in a study conducted on the quality of ground water in Benin City, Nigeria found unacceptable levels of aerobic bacteria and fungi present in borehole water of Teboga District of Benin City. In another similar work, Eniola et al [30] obtained a range of 5.0 x10 2 to 7.0 x 10 2 cfu/ml for stored borehole water samples.…”

“…The findings of this study agree with those of Ogbonna, et al, (2007) on physicochemical parameters of borehole water from Borokiri area of Port Harcourt. However, they contrast Erah et al, (2002) report for quality of boreholes and open wells in Benin City which were contaminated with abnormal levels of dangerous chemicals. Earlier researchers attributed high concentration of mineral salts to the geological nature of the bed rock in which the aquifers are situated, anthropogenic activities, inadequate seals, split castings, wrong choice of materials for casing which may have led to rusting and corrosion hence chemical pollution of the water supply (Ifeadi, 1982;Adeyemo et al, 2002).…”

“…Acute effects such as; nausea, lung irritation, skin rash, vomiting, dizziness and in the extreme death have been reported (Erah et al, 2002). More so, effect of iron overload on some organs such as skin, is trivial, compare to hemosiderotic harm to other organs, like the liver and kidney, which can be fatal (Anon, 1976).…”

This study was undertaken to assess potability in relation to physicochemical quality characteristics of borehole water in Abonnema Community of Rivers State. The sampling sites were divided into five zones namely Bob-Manuel, Jack, Briggs, New Site and Obonoma. Water samples from various sites such as urban area, new site and rural areas were obtained. Standard sampling and analysis were done aseptically at different locations according to the compounds and sites of water supply. The result of the analysis showed that the pH values across the zones had a mean range of 6.2 + 0.2 to 6.8 + 0.4, while conductivity values for Briggs and Obonoma compounds were 47.8 and 50.6 µs/cm respectively. However, the study revealed that Mg, Fe, SO 4 and CO 2 contents were in greater amounts in the rural area and new site while chloride and copper were relatively low in the same water sites. Total alkalinity ranged between 35.2 + 9.7 and 112.7 + 7.1 mg/l in the water samples and is below the permissible limits for drinking water. From the findings of this study, borehole water samples from urban are more potable than those of new site and rural area. The public health implications for people of Abonnema who depend on these sources of water supply daily have been discussed. Treatment of boreholes, boiling and filtering of drinking water as well as improved sanitary conditions and personal hygiene were advocated. Government should as a matter of urgency ensure appreciable decline in the level of water pollution through routine monitoring of groundwater and anthropogenic activities in the zone.

“…Apart from the phytotoxicity, long exposure of Al, Pb, Cd, Cu, Cr and Mn to man can pose serious health hazards. According to Erah et al (2002), chronic exposure of man to Pb can cause Pb-poisoning, interference in red-blood cell chemistry, nervous system damage, mental defects, and IQ depressions in children. Cd in man and animals causes kidney and liver dysfunction, hypertension and heart diseases.…”

The ancient Benin moat of 2.00 to 5.00 m width, and 10 to 30 m depth almost concentrically dug round the City, is supposed to be an important socio-cultural artifact if well preserved. It has served its good purpose of defense and protection of the ancient Bini civilization. Now, modern urbanization pressure has defaced and is degrading the moat and its environs through house development, soil quarrying, gullying, flood catchment, and waste disposal. Because of its extent, it is pertinent to understand its pedo-geological and hydrogeological setting in order to assess the impact of the waste disposal on the soil and groundwater systems. Random; 11 soil (pool) samples at 0.0 to 0.5 m depth, and eight groundwater samples from pumping boreholes, 0.5 to 10.0 m on both sides of the moat were drawn. Samples were analyzed for their chemical, heavy metal constituents (including microbial in water). Comparisons of means with pristine locations in previous studies were conducted using one way analysis of variance (ANOVA) at 5% α level of significance. Results reveal contamination of soil with Al, Cd, Fe, Pb and THC at P<0.05. The groundwater also is polluted with presumptive coliform of 1.0 x 10 2 to 1.5 x 10 3 cfu/ml -1 and heavy metals; Al, Cd, and Pb at P<0.01 indicating high significant difference. This indicates that the once protective moat is now a likely area of phytotoxicity and general environmental toxicity to man if chronic exposure is allowed by continual waste disposal.
