Qualitative Assessment of Some Available Water Resources in Efon-Alaaye, Ekiti State Nigeria
As water is a major life sustainer, hence its portability is of great importance in performing that role well. In this study, various water samples were collected within Efon-Alaaye for both physicochemical and bacteriological tests. A total of nine (9) water samples were taken for analysis with six (6) from various surface sources and three (3) from groundwater sources in the study area. The mean turbidity value, temperature, total dissolved solids
(TDS) concentration, hardness and EC are 2.92 NTU, 23°C, 447.8 mg/l, 48.1 mg/l and 138.4 μS/cm respectively. Manganese has mean value of 0.27 mg/l. The concentration of both copper and zinc ranges from 0.07 – 0.13 mg/l and 0.16 – 0.55 mg/l with an average value of 0.04 mg/l and 0.28 mg/l respectively. Water samples collected were also analyzed for total coliform bacteria and ranged from 1 to 4.6/100 ml with an average value of 3.29 colony/100 ml. On the basis of findings, the physico-chemical analysis reveals that some of the water samples were above the WHO standards for parameters like turbidity and TDS while the bacteriological test reveals that seven (7) of the water samples considered met the WHO requirement of portability while the other two samples contain faecal contaminant as E.coli
was discovered, though at reasonable rate.
