Mafikeng, the capital of the North West Province, receives water from two sources, namely the Molopo eye and the Modimola dam. Once treated, the potable water is mixed and supplied to the city via distribution systems. This study was designed to assess the quality of drinking water in Mafikeng and also to determine whether the water from the two sources has an impact on the mixed water quality. Physico-chemical parameters and bacteriological quality (faecal coliforms (FCs), total coliforms (TCs), heterotrophic bacteria and Peudomonas spp.) was monitored at three drinking water sites weekly for 4 months. The results revealed that the physico-chemical quality of the water was generally acceptable. The pH ranged from 5.7 ± 0.18 to 8.6 ± 0.14, the temperature ranged from 18.3 ± 0.69 to 25.1 ± 0.69 °C and the total dissolved solids (TDS) ranged from 159.9 ± 22.44 to 364.4 ± 12.44 mg/l. These values are within the target water quality range for drinking water as prescribed by WHO, Department of Water Affairs and SANS 241. What is of concern was the microbial quality of the water. FCs, TCs, heterotrophic bacteria and Pseudomonas spp. were present in some of the treated water samples. The most significant finding of this study is that all drinking water samples were positive for Pseudomonas spp. (>100/100 ml).

Introduction: Safe water is a precondition for health and development and is a basic human right, yet it is still denied to hundreds of millions of people throughout the developing world. Water-related diseases caused by insufficient safe water supplies, coupled with poor sanitation and hygiene, cause 3.4 million deaths a year, mostly in children. Methodology: The present study was conducted on 1,317 drinking water samples from various water sources in Amritsar district in northern India. All the samples were analyzed to assess bacteriological quality of water for presumptive coliform count by the multiple tube test. Results: A total of 42.9% (565/1,317) samples from various sources were found to be unfit for human consumption. Of the total 565 unsatisfactory samples, 253 were from submersible pumps, 197 were from taps of piped supply (domestic/public), 79 were from hand pumps, and 36 were from various other sources A significantly high level of contamination was observed in samples collected from submersible pumps (47.6%) and water tanks (47.3%), as these sources of water are more exposed and liable to contamination. Conclusions: Despite continuous efforts by the government, civil society, and the international community, over a billion people still do not have access to improved water resources. Bacteriological assessment of all sources of drinking should be planned and conducted on regular basis to prevent waterborne dissemination of diseases.

Cases, concerns and complaints in public about refill drinking water,  low businessmen DAMIU are checked routinely product processed as well as the mandate of the Consumer Protection Act, Kepmerindag RI and Permenkes RI on monitoring refill drinking water background for the author to conduct research. Purpose to describe the bacteriological quality of refill drinking water in terms of disinfection method used in District Ngawi. This method is descriptive study and cluster sampling to 49 samples DAMIU in District Ngawi with the results of the method used, namely ultraviolet disinfection, ozonation and reverse  osmosis. The results bacteriological quality (total coliforms) of any disinfection method shows a different picture, which shows the method of disinfection reverse osmosis bacteriological quality with the percentage of 50.00%, followed by ozonation method of 46.15% and the latter by the ultraviolet method percentage value 44.12 %. The ability of any reduction in total coliform disinfection method shows a different picture, in which the reverse osmosis method of disinfection showed total coliform reduction percentage of 94.08%, followed by ozonation method of 91.46% and the latter by the ultraviolet method percentage value 86.09%. The conclusion willingness, support and cooperation of all stakeholders is needed to improve the supervision, guidance and inspection of the quality of refill drinking water in Ngawi. Key word : water, disinfection, coliform
