Most people in the rural areas, due to high cost of treatment of water, resort to readily available sources of water which are of low quality and thereby get themselves exposed to water borne diseases. This therefore approves the aim of this study which is to determine the degree of purity of water sources in Bali metropolis of Taraba State, Nigeria as treated with Moringa oleifera (zogalle), commercial Alum, and their combination. The phyisco-chemical properties investigated for in the raw and treated water were pH, total dissolved solids (TDS), and turbidity. The pH of the various raw water sources investigated were 7.26 for well water, 8.00 for pond, 7.64 for river Taraba water and 7.50 for borehole. When Moringa oleifera seed powder was used as a sole coagulant in the treatment of the various sources of water, it was observed that the pH of the water sources reduced to the recommended range set by World Health Organization standard for drinking water. The investigation using 5g i.e. (1g/2) Moringa oleifera seed powder to treat different water sources after 24hrs showed that the pH reduced to 6.50 for well, 6.50 for pond, 7.11 for River Taraba water and 6.02 for borehole. There was little increment in value of Total Dissolved Solid in some of the treated water sources than the raw water sources indicating high dissolution of Moringa oleifera in the solution. These increments were observed in Borehole and river water. The turbidity test showed that Moringa dose reduced the different sources of water turbidity to 17.1 NTU, 20.8 NTU, 18.1 NTU and 16.2 NTU for well, pond, river and borehole against 102.0 NTU, 115.5 NTU, 104.3 NTU and 99.10 NTU respectively for a settled period of 2 h. This gave a reduction value of 83.23%, 81.99%, 82.64% and 83.65% for well, pond, river and borehole respectively. Therefore, this investigation about the use of Moringa oleifera for the treatment of drinking water may be an important, sustainable, and affordable indigenous method towards reduction, and improvement of quality of life for a larger size of the poor by providing extra income and food.
