Abstract

Some organisms and chemicals are hazardous to human health if found in drinking water. Drinking water should be free of suspended particles. It must be colourless, odourless and tasteless .In order to achieve the stated qualities of water, water is being treated with chlorine and fluoride in Taraba State. It is clear to us that high concentrations of fluoride (above 1.5 mg/litre, the WHO guideline value) can damage bones and teeth. Chlorine compounds on the other hands destroy pathogens after 30 minutes of contact time. The amount of chlorine that will be needed to kill the pathogens will be affected by the quality of the untreated water and by the strength of the chlorine compound used. The addition of chlorine in excess will do more harms than good to human health and for this reason, we have decided to carry out this research so as to find out if the amount of chlorine and fluoride being added into water for treatment is adequate. Data was collected from Taraba State Water Board. The data covered the whole 2015 that is from January to December, 2015. Water treatment is gone daily, but we selected data for four days in each month at random. Pearson’s correlation coefficient and Analysis of Variance methods were used in the analysis. The significance of the correlation coefficient results was tested by the use of student t-distribution test. The results from both Correlation and Analysis of Variance show that the amount of chlorine and fluoride used in water treatment in Taraba State is statistically adequate.
