Abstract

Twenty (20) water samples were randomly collected from different hand dug wells in three localities in Ekiti-State; namely: - Ado-Ekiti, Iyin Ekiti and Ilawe Ekiti. They were analyzed for their physical, chemical and bacteriological properties. The physical tests included taste, color and odor. The chemical tests also included cations and anions determination while the bacteriological analysis carried out on the water samples involves determination of E–coli and total bacteria counts. Other parameters tested are the conductivity, total hardness, trace elements, total dissolved solids and alkalinity. The result of the physical tests revealed that the water is colourless, odourless and tasteless, while the result off the chemical tests revealed that the pH ranges from 6.0–7.3, indicating that the water samples are slightly acidic to alkaline, temperature ranges from 27.30c–32.10c, Electrical conductivity ranges from 20–750 Ns/cm, total hardness ranges from (30-400)mg/L and Total dissolved solids ranges from13.4-503(mg/L).The analyzed cations and anions in the samples showed that ca2+ ranges from (4.8 – 139.5)mg/l, Mg2+ (3.4-25.9)mg/l, Na+ (6.5-130.7)mg/l and K+ (3.9-26.80)mg/l, while the anions showed that HCO3- ranges from (14-142) mg/L, CL (10.0-201) mg/L; SO42- (3-62) mg/L and NO32- (0.8-6.8)mg/L. The present of HCO3- in the water samples revealed that the water is moderately soft to hard, the soft to moderately hard nature of the water samples make them suitable for a wide range of industrial applications.
