Assessment of Borehole Water Quality in OredoMunicipality
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 10
Abstract
In Oredo municipality, households basically rely on groundwater sources as their only source of water to meet their ever-growing water demands and as such the need to study the quality of these sources of water arises. Water samples were collected from 15 boreholes located within the study area and their physicochemical and microbial parameters assessed. The laboratory results obtained were compared with standards limits specified by World Health Organization (WHO) and the Nigerian Standard for Drinking Water Quality (NSDWQ).Results of the pyhsico-chemical tests conducted on the water samples indicated that all the parameters except pH and nitrate were within the permissible limits given by the WHO and the NSDWQ. pH values ranged from 4.0 -6.5, withonly BS12 having a pH of 6.5. Also, nitrate values were above both standards in water samples fromBS4, BS5, BS6, BS9 and BS14 (68-81.5mg/l), whilewater samples fromBS1, BS2,BS3,BS7,BS8,BS11 and BS15 (15.2-43.9 mg/l) were above the set standard by WHO but below that of NSDWQ. Coliform was present in samples BS4, BS5, BS6,BS7, BS8, BS14 and BS15 in amounts that are above the permissible limits. This signifies about 50% of water samples tested. The presence of coliform bacteria in borehole water source has been attributed to the unhygienic environment around the water source. It is recommended that water from borehole sources in the locality should be treated to minimize water related diseases.
