Chemical analysis of drinking water from some communities in theBrong Ahafo region



This study consisted of the determination of the trace metals and some physiochemical properties in drinking water samples from the Brong Ahafo region of the Republic of Ghana, where drinking water samples are nottreated before it is consumed. The purpose was to ascertain the quality of water from these sources. Samples weretaken from fifteen sampling points and analyzed for the following parameters Fe, Cu, Mn, Zn, Al, NO3-, NO2-, SO42-, PO42-, and F- using the procedure outline in the Palintest Photometer Method. The data showed the variation of theinvestigated parameters in samples as follows: pH 5.57-7.54, conductivity (EC) 35-1216 μs/cm, turbidity 3.25-72.50NTU, PO42- 1 0.32-9.30 mg/L, F- 0.32-1.05 mg/L, NO3- 0.09-0.99 mg/L, NO2- 0.006-0.114 mg/L, SO4 2- 3.33-8.02 mg/L,Cu 1.19-2.75 mg/L Fe 0.05-0.85mg/L, Zn 0.04-0.15 mg/L, Mn 0.003-0.011 mg/L and Al 0.05-0.15 mg/L. Theconcentrations of most of the investigated parameters in the drinking water samples from Brong Ahafo region werewithin the permissible limits of the World Health Organization drinking water quality guidelines. There were nocorrelations between metal concentrations in the drinking water samples.
