Pipe borne water supplied to Nigerian households may not always meet the accepted drinking water quality standards due to possible water pipe damage. The objective of this study was, therefore, to develop a portable water filter device for improving household drinking water quality. Five litres of representative tap water samples collected from Lagos State University Staff quarters were passed through the developed device. The experimental variables investigated for data acquisition were aeration period of untreated tap water; device backwashing operation cycles and retention times of tap water in the filter device. The results of the analyses of water samples for the various values of the experimental variables showed that the range values of water parameters between the treated and untreated tap water samples were 0.04-0.05, 0.02-0.03, 0.04-0.12, 0.3-0.4, 125-137, 10-20, 3-10 mg/L for barium, chromium, iron, pH, Total Dissolved Solids, hardness and chloride, respectively. Although the developed device helped in improving the quality of the tap water; the p-values for the different experimental variables were greater than α-level of 0.05 indicating the non-significance of using the developed water device. Consequently, future study will consider other experimental variables that will justify the significance of using the developed device.

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

Biodegradable Dissolved Organic Carbon

Total organic carbon (TOC) present in surface water consists of different fractions like dissolved organic carbon (DOC) or biodegradable dissolved organic carbon (BDOC). BDOC may have an impact on the bacteriological quality of water as it can be a source of carbon and energy for microorganisms. It is important to consider this parameter in case of the distribution of drinking water. The aim of this research was to compare the qualities of chosen surface water in Poland and Germany in terms of concentration of total organic carbon and its fractions. The samples were taken from the reservoir in Poland and Rhine River in Germany. The first one is a source of drinking water for humans. The research showed that, considering the analyzed compounds, the water from the river has better quality.
