Physicochemical Properties Evaluation of Well and Borehole Water-Samples from Elebu District, Iddo LGA, Ibadan, Nigeria

Throughout ages, water has proven to be an indispensable liquid for life,food production, agriculture, domestic and industrial uses. Access topotable water in Nigeria poses a challenge due to infrastructural deficit.Well and boreholes remain major sources of potable water and in eventof poor practices, the risk of contamination is imminent. Hence,continuous evaluation of water quality designated for specific purposesremains a necessity and is thus the underpinning of this study. A total ofeleven (11) sites namely: Eleta, Yidi, Akuru, Adedayo, Kuyoro, Elebumarket, Ajokankan, Health centre, Police station, Lawyer Oke, Olanlegestreets, respectively were randomly selected from Elebu district. Tensamples each from well and borehole were collected and analyzed forphysicochemical properties: pH, Conductivity (C); Total DissolvedSolids (TDS), Alkalinity, Salinity, hydrogen ion concentration (H+), (pH)were determined in the laboratory using standard techniques. Salinity, TDS and conductivity between January to March, 2024. Results revealedthat pH of well and borehole water varied between 6.36±0.02 to7.21±0.02 and 6.40± 0.01 to 7.10± 0.02 respectively and fell withinWHO recommended limits of 6.4 to 8.5. Furthermore, the totalhardness of well and borehole water ranged between 4.92±0.02 mg/Lto 15.40± 0.10 mg/L and 7.84± 0.02 mg/L to 12.43 to 0.02 mg/Lrespectively and fell within World Health Organization (WHO)recommended limits of 0.0 to 180.0 mg/L. Iron (Fe) content of well andborehole water ranged between 1.21±0.21 mg/L to 3.17± 0.03 mg/Land 1.91± 0.03 mg/L to 3.84± 0.04 mg/L respectively which far exceedsWHO standards of 0.3 mg/L to 1.0 mg/L. Results from this study indicatethat water from the wells and borehole in Elebu district of Ibadan is highin iron content load, hence there is need for water treatment procedureto engender safe water supply to the district.
