Drinking Water Sources

Most water supply programmes in Cambodia have focused on providing access to bacteriologically safe water, an approach which has led to an increasing reliance on ground water, especially in rural areas. However, there have been very few data collected on the chemical quality of the nation's drinking water sources, and few water supply programmes have the capacity to assess chemical quality. The study was designed to address this data gap by conducting a low-cost, rapid assessment of drinking water sources nationwide to determine whether there were any chemicals of concern in Cambodian water supply sources. Results of the assessment confirm that there are several parameters of health and aesthetic concern; dissolved arsenic is the most significant. Elevated arsenic levels (some exceeding 500 μg l-1) were detected in aquifers of moderate depth in several highly populated areas, confirming that further investigation of the occurrence of arsenic contamination in Cambodia is warranted. Other chemicals of health concern include nitrate, nitrite, fluoride and manganese. Additionally, many ground water sources are negatively impacted by parameters of aesthetic concern, such as iron, manganese, hardness and total dissolved solids. Elevated levels of these parameters have caused consumers to reject newly installed water supplies, often in favour of surface water sources that are bacteriologically unsafe.

Abstract PT. XYZ is a company engaged in producing bottled drinking water. To compete in the market, it is demanded to maintain the quality of the goods produced because of the quality products so that it has the aim of knowing the causes of significant product defects in the 240 ml cup packaging at PT. XYZ and knowing what factors cause defects in 240 ml cup packaging products at PT. XYZ Abstract is written in Indonesian as well as using the seven tools method. The results show that the cause of product defects is based on the cause and effect diagram of lid defects including: 1) leaking lid: Heater is not hot enough, heater is too hot, bucket with trimming is not center, seal disk is dirty and operators are less careful. 2) Broken lid: The lid is brittle and the handling is not good 3) Tilted lid: The position of the roll lid shakes and the operator is not careful.    Keywords: Quality, product defects, Seven Tools   Abstrak XYZ merupakan perusahaan yang bergerak di bidang memproduksi air minum dalam kemasan. Untuk bersaing di pasaran maka di tuntut untuk menjaga kualitas dari barang yang di hasilkan karena produk yang berkualitas sehingga memiliki tujuan untuk mengetahui penyebab kecacat produk yang signifikan pada kemasan cup 240 ml di PT. XYZ dan mengetahui Faktor-faktor apa yang menjadi penyebab ke cacat produk kemasan cup 240 ml di PT. XYZ Abstrak ditulis dalam Bahasa Indonesia segingga dengan menggunakan metode seven tools di dapatkan hasil bahwa Penyebab terjadinya kecacatan produk berdasarkan diagram sebab akibat cacat lid diantaranya:  1) bocor lid : Heater kurang Panas, heater terlalu panas, bucket dengan trimming tidak center, seal disk kotor dan operator kurang cermat. 2) Pecah lid : Lid getas dan handling kurang baik 3) Lid Miring : Kedudukan roll lid goyang dan operator kurang teliti.   Kata Kunci: Kualitas, cacat produk, Seven Tools

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.
