Tap Water Quality

Abstract Samples of bottled water (n = 172) offered for sale in Canada were analyzed for lead, cadmium, arsenic, aluminum, and fluoride: means and ranges (μg/g) found were, respectively, 0.0026 (<0.0010- 0.074), 0.00018 (<0.0001-0.0004), 0.0030 (<0.001- 0.048), 0.027 (<0.010-0.568), and 0.543 (<0.050- 5.85). Comparison of levels among mineral waters (n = 64), spring waters (n = 77), and miscellaneous waters (n = 31) indicated appreciable differences only in the case of fluoride. For fluoride, the means and medians (μg/g) for mineral, spring, and miscellaneous waters were 1.179 and 0.455, 0.152 and 0.090, and 0.201 and <0.050, respectively. No samples were found in violation of the tolerances in the Canadian Food and Drug Regulations; however, 1 sample (in a lead-soldered can) contained lead and 15 samples contained fluoride at levels above the limits recommended by the Guidelines for Canadian Drinking Water (tap-water) Quality.

Background: The main objective of this study was to investigate the logics behind tendencies towards bottled drinking water usage in spite of availability of treated tap water. The amount of waste bottle is also estimated in Iran and managing principles for resolving the issue presented. Methods: A questionnaire was used to survey the logics behind tendencies toward bottled drinking water consumption among 120 participants. In order to estimate the quantities of the PET wastes produced in the country, data about bottled water production rate as well as volume of the imported and exported drinking bottled water were collected from 1962 to 2015 and applied in the calculations. Results: Findings suggested that about 0.026 to 3.86 billion liters (about 1.04 billion literson average) of bottled water was consumed annually between 2000 and 2015. Furthermore, bottled water consumption increased from 0.41 to 48.9 L/capita-year within the same time period. In the meantime, the plastic bottle waste generation rate rose from 12.84 to 1519.38 g/capita-year. There is no efficient and suitable system for managing and recycling waste bottles in the country. The perceived unreliability of tap water quality was the main reason of bottled water consumption among 74% of the respondents. Conclusion: To reduce bottled water consumption and the associated harmful environmental and health consequences, measures such as informing people, validating public water supply quality, preventive rules enactment, and establishing extended producer responsibility (EPR) are highly recommended.

Tap Water Quality

Parallel to the increase in public concern about the safety of drinking water globally, the demand for bottled water has increased in almost every country. Although tap water is significantly cheaper than bottled water, consumers concerned about the safety of tap water. They still prefer the bottled water despite several checks implemented in tap water networks. The present paper aims to discuss network water quality in the city of Istanbul, Turkey and to present the findings on a related survey conducted by the authors. The survey was conducted with the participation of 980 individuals living in different districts in Istanbul and the findings were assessed to determine the public perception about tap water quality and bottled water consumption especially after the experienced years of drought and water quality concerns. Findings demonstrated that several individuals never drink tap water and certain individuals do not utilize tap water at all. It was found that only 4% in the surveyed group drink tap water without hesitation. Based on survey findings, the abovementioned group was mainly among the lowest income group in the sample. When purchasing bottled water, several individuals preferred the well-known brands. It was found that the most significant reasons for preferring bottled water were the nice taste of the bottled spring water, which was perceived not to exist in tap water. It was concluded that drinking water treatment facilities and regulations are required to cater the future quality demands. Furthermore, it was determined that adequate inspections and controls on network water are necessary.

AbstractMany people prefer to drink bottled water instead off the tap water. The bottled water is stored in the plastic bottles sometimes for long time. These plastic bottles might leach out some harmful materials into the water especially when exposed to temperature alteration, which may affect human health. This research work focused on investigating the effect of changing temperature on the bottled water quality. The work studied the effect of heating water in plastic bottles by sun, oven, and microwave. The study included also the impact of cooling and freezing the bottled waters. Results showed that temperature alterations caused changes in some physicochemical properties of bottled waters such as decreasing the values of pH and TDS and increasing levels of fluoride and chloride. In addition, the concentration levels of some physiochemical parameters exceeded the permissible values for drinking water. With temperature alterations, all levels of heavy metals in bottled waters were minimal except some small concentrations of copper and zinc. Results confirmed also differences in behavior between the bottled water brands exposed to the same temperature alterations. Heating bottled waters above 50 °C is alarming problem on the water quality. This is because above this degree, many alternations were observed in the water content. The outcomes of this work are useful for improving the current legislation on bottled waters and their storage.

The microbiological monitoring of mineral bottled waters results is crucial for the prevention of outbreaks in consumers. European and International regulations establish the quality of water intended for human consumption in order to preserve human health from the negative effects deriving from water contamination. Advanced methods targeting the faster detection of potential pathogens in drinking water may consent to the creation of an early warning system, enhancing water quality management. This study aimed to suggest the implementation of standard water quality evaluations, based on the characterization of the microbial composition of mineral bottled water brands, contributing to the periodic control of the water’s microbiological stability along with the shelf life, and, consequently, the stability of the supplying sources. Bottled water microbiota analysis was combined with the qualitative and quantitative evaluation of microbial loads in time, and the monitoring was performed in two seasons and two different storage conditions for a total of sixty days. The employment of molecular microbiology techniques (NGS and Sanger sequencing), compared to standardized cultural methods and integrated with metagenomic analysis, combining chemical and physical indicators for each sample, allowing for the generation of specific fingerprints for mineral bottled waters, pointing at simplifying and improving the foreseen risk assessment strategies to ensure the adequate traceability, quality and safety management of drinking water.

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.

Tap Water Quality

A questionnaire survey was conducted in order to assess residents’ perceptions of water quality for drinking and recreational purposes in a mid-sized city in northcentral West Virginia. Two logistic regression analyses were conducted in order to investigate the factors that influence bottle use and filter use. Results show that 37% of respondents primarily use bottled water and that 58% use a household filter when drinking from the tap. Respondents with lower levels of environmental concern, education levels, and lower organoleptic perceptions were most likely to perceive health risks from tap water consumption, and were most likely to use bottled water. Income, age, and organoleptic perceptions were predictors of water filter use among respondents. Clean water for recreational purposes was not found to be significant with either of these models. Our results demonstrate that bottle use and filter use are explained differently. We argue that more education and better communication about local tap water quality would decrease the use of bottled water. We demonstrate that household filters could be used as an alternative to bottled water.

Requisite reference facts about essential elements in treated and plastic bottled drinking water is usually mentioned on the products. However, more information is sometime crucial regarding trace elements in treated, bottled and other sources of drinking water such as tap water to evaluate their quality. This study is aimed to evaluate drinking water quality in the main governorates (Jazan, Sabya and Abu Arish) of Jazan province located in the South-Western region of Kingdom of Saudi Arabia. This is the first such study carried out in Jazan city so that the research team can come out with valuable recommendations in the issue. The research team has collected a sum of 68 water samples from different sources comprising hospitals (treated tap water), stations for drinking water treatment (large blue bottles of drinking water) and bottled drinking water (purchased from local markets). Using inductively coupled plasma-mass spectrometry (ICP-MS), the concentrations of 20 elements were determined. The physiochemical parameters of water samples were measured. All parameters were within the recommended limits of the World Health Organization (WHO, 2011) and Gulf Cooperation Council Standardization Organization (GSO, 2008). Trace and major elements were found to be below the standard guideline values , except for uranium in some tap water samples. This preliminary study will significantly improve the awareness and knowledge among the society about the drinking water quality in Jazan area.

Introduction: Current legislation permits a phased achievement of drinking water quality standards by making decisions on temporary deviations from hygienic standards for the period of design, construction, and/or upgrade of water supply facilities. Objective: To substantiate the mechanism for coordinating temporary deviations of concentrations of certain chemicals in drinking water from hygienic standards for the period of implementing measures for water quality improvement. Materials and methods: We applied methods of sanitary and epidemiological expert examination and assessment and the method of system analysis to review and study current regulations, results of laboratory testing of water quality in centralized cold water supply systems for 2011–2019, and action plans of 83 constituent entities of the Russian Federation for improvement of tap water quality. Results: We established that violation of hygienic standards was most often registered for aluminum, boron, bromine, iron, silicon, lithium, magnesium, manganese, sodium, and chloroform. Hygienic requirements for tap water quality determine necessary technological solutions to be implemented at water treatment facilities; yet, their implementation requires a certain amount of time and might cause temporary tap water quality deterioration making it necessary to agree with the local bodies in charge of federal sanitary and epidemiological surveillance a phased transition to eliminating threat to public health from poor quality drinking water. Conclusions: The authors propose an algorithm for conducting a risk assessment and a mechanism for decision making on temporary deviations.

Abstract West Virginia has had a history of water quality issues. In parallel, the world is facing a plastic pollution crisis. In order to better understand behavioral responses to perceived water quality, a survey was conducted at a major research university to ask participants about water quality perceptions and drinking water behaviors. A total of 4,188 students completed the survey during the Spring 2017 semester. Logistic regression analyses were used to predict behaviors. Results indicated that a third of the student population primarily used bottled water for drinking purposes at home, while 39% used a filter at home and 26% drank water directly from the tap. On campus, bottled water use was reported by 36% of the students, water fountain use represented 31%, and 29% of the students brought their own water with reusable cups/bottles. Health risk perceptions, organoleptic perceptions (i.e., taste, odor, color), and environmental concern were predictors of the different behaviors. Students originally from West Virginia had a higher propensity of using bottled water. We argue that bottled water consumption should be reduced in areas where water quality is not an issue. In this sense, there is a need for education among the student population in West Virginia.
