Mechanisms Of Formation

Lyon, France has the opportunity to distribute in abundance a groundwater resource with a good quality for drinking water. However, the length and the complexity of the distribution network can lead to consumer complaints in some areas of the water distribution system. In order to improve the organoleptic quality of distributed water, the water supplier wants to get a better understanding of potential taste and odour formation and to succeed in controlling it. Since 2006, activities have been taken with targeted analyses and sensory evaluation of water, taking into account both the consumers' private networks and the citywide distribution network. The first results were focused on the occurrence of bromophenols along the water distribution system, the understanding of the mechanisms of formation of such compounds, as well as their incidence on taste-and-odour events at the consumer's home.

Background: Today possibility of rendering water non-potable by various types of contaminants (physical, chemical and biological) is of considerable importance. It is not only the microbial con­taminants but also the physical and chemical contaminants, playing an important role in compro­mising our health in many ways. The aim of this study was to assess the physical, chemical and the microbiological quality of commercially produced bottled water in Pokhara city. Methods: A study was conducted to assess the quality of bottled drinking water produced in Pokhara city. Total of 21 brands of bottled water was collected, first batch in monsoon season and second batch in pre-monsoon season, from the market. The physical, chemical and microbial as­sessment was carried out as per National Drinking Water Quality Standards, 2062. Coefficient of variation and t-test were applied where applicable. Results: Better water quality was found in Pre-monsoon season than that of monsoon season, in regard to microbial assessment. None of the samples in first batch tested positive for coliform whereas in second batch 38.2% of samples tested positive for coliform. Coefficient of variation for pH and chloride content was, 8.9% and 6.1%, 35.6% and24.19%, in pre-monsoon and monsoon season respectively. Both were found to be statistically significant. While other tested parameters were within normal limits. Conclusions: The quality bottled drinking water available for sale do not meet the standards given by National Drinking Water Quality Standards, particularly the microbial quality.

Background: Bottled drinking water has become popular for consumption by customers. Bottled drinking water with pathogenic microbiological contamination is a public health concern. This study aimed to describe the current situation of microbiological contamination in bottled drinking water products, food safety conditions and some influencing factors in production facilities in Hau Giang province in 2020. Methods: A cross-sectional study has been conducted in 2020 using quantitative and qualitative methods. The evaluation was carried out at 54 bottled drinking water production facilities, 108 workers/owners and 54 samples collected from facilities for microbiological analysis in the province. In-depth interviews were conducted with local government officials on food safety, two owners of facilities and two workers. Results: It showed that the proportion of microbiological contamination in bottled drinking water accounted for 18.5%, of which P. aeruginosa contamination was 18.5%; and Coliform contamination was 3.7%; No drinking water samples were contaminated with E. coli. 79.6% of facilities met general food safety conditions. There were several factors affecting the proportion of microbiological contamination of bottled drinking water as follows: Bad compliance with food safety in production for the sake of profit by workers, affecting the quality of products such as trash cans without lids; No sterilization treatment before filling; Non-sterilization in filling room. Non-monitoring of UV lights for replacement; No regular cleaning of water pipes, tanks, and discharge valves; Difficulty in state management of food safety for facilities of bottled drinking water production, such as insufficient manpower, lack of equipment and funding for activities. Conclusion: The quality of bottled drinking water in Hau Giang province was not good. The important factors affecting the contaminated bottled drinking water products were identified. We recommend that: management agencies should frequently conduct sudden inspections and supervisions of facilities with no ensured food safety and strictly handle according to regulations. Owners of bottled water facilities should voluntarily comply with food safety. This study is particularly concerned with ensuring food safety conditions in the production of bottled drinking water to prevent products from microbiological contamination. Keywords: Microbiological contamination; E. coli, Coliform, P. aeruginosa; bottled drinking water; food safety conditions; Hau Giang province.
