ABSTRACT
Water can be classified as atmospheric water, surface water and underground water. Underground water is also referred to as ground water. Ground water is generally less susceptible to contamination and pollution when compared to surface water bodies. Ground water (e.g. borehole water) is not completely protected from contaminants, which could be either microbial or inorganic agent or even due to human activities and environmental conditions. Some studies have found that water from some borehole do not meet the WHO standard for drinking water. To ensure that the water is safe for drinking and domestic use, a Whole House Water Filter is connected to the point of entry.
This study was conducted in Warri, Warri South, Effurun, Uvwie Local government areas in Delta State and as well as two Local government areas in Edo State, namely: Egor and Ovia North-East Local government areas. Samples were taken over a period of three months beginning from April, 2019 to June, 2019. A total of thirty-six (36) water samples were collected using sterile sampling bottles according to the standard methods as described by American Public Health Association. Water samples were collected from boreholes with standard Whole House Water Filters and boreholes without standard Whole House Water Filters at different locations in Warri, Warri South and Effurun, Uvwie Local government areas in Delta State respectively. Water samples were also collected from boreholes without standard Whole House Water Filters at different locations in Egor and Ovia North-East Local government areas in Edo state respectively. Thorough chemical and biological analyses were carried out on all the samples for the entire duration. Standard culture- based methods were adopted in the isolation and identification of the bacteria isolates. The antibiotics sensitivity tests were also carried out as well as test for heavy metals.
