ABSTRACT

Physicochemical and microbiological quality of water samples from some hand-dug wells in Iworoko-Ekiti, Nigeria were investigated. The coliform count ranged between 25 and 1,600 per 100mls of the original water sample. Physico-chemical values ranged; pH (6.30-8.90), conductivity (1.20-5.30), acidity (7.50-9.60mg/ml), alkalinity (27-170mg/l), chloride (0.11-3.20mg/l), free CO2 (0.23-1.95mg/l), total solid (0.20-1.60mg/l) total suspended solids (0.10-1.20mg/l) respectively. Values for minerals ranged; Zn (0.19-0.70), Fe (0.24-0.66), Pb (0.01-0.04), Ca (3.28-32.24), Mg (1.98-15.36), Na (1.01-4.69) and K (1.077-6.715). There is no evidence on the effect of installation of concrete ring casting in wells on the quality of the water as samples from either ringed or unringed wells were almost of the same quality.
