ABSTRACT

The study aimed to assess the quality of drinking water in Olowotedo community of Ogun state, Nigeria. Five samples were taken from different sources (wells, borehole, tap and sachet water) were analyzed, Selection of water samples was carried out using proportionate allocation, equal allocation, simple random sampling  and systematic sampling methods depending on the stage. The water  quality parameters examined and their results for all the five water samples were; colour having 0.0TCU, taste and odour were absent, temperature was 24.7oC, 26.2oC, 25.6oC, 25.5oC and 25.7oC respectively, turbidity was 0.0NTu, sulphate was 0.0ppm, Ph was 7.42, 7.24, 7.75, 8.15 and 8.55 respectively, hardness was >150ppm, nitrate was >10mg/L, >10mg/L, >3.4mg/L, >1.94mg/L and >1.0mg/L respectively, iron was 1.65mg/L, 0.25mg/L, 1.5mg/L, 1.85mg/L and 1.7mg/L respectively, chloride was 62ppm, 15ppm, 50ppm, 60ppm and 65ppm respectively, resistivity was-1 , conductivity was 246, 223, 362, 400 and 400 respectively, salinity was 400, TDS was 144.8mg/L, 142.4/L, 219mg/L, 116.7mg/L and 114.8mg/L respectively, coliform and E-coli were only present in one of the five samples.

Finally, there is an urgent need to improve on the quality of drinking water in Olowotedo town coupled with mass health education to the community.
