Although access to safe drinking water is one of the most important health-related infrastructure programs in the world, drinking water remains a large problem in China today, especially in rural areas. Despite increased government investment in water resource protection and management, there is still an absence of academic studies that are able to document what path the investment has taken and whether it has had any tangible impact. The purpose of this paper is to analyze the impact of drinking water investment on drinking water in China.

The authors make use of nationally representative data from 2005 and 2012 to measure the impact of drinking water investment among 2,028 rural households in 101 villages across five provinces. Both ordinary least squares regression and probit regression are used to analyze the correlates and the impact of drinking water investment.

The authors demonstrate that water quality was likely a significant problem in 2004 but that China’s investment into drinking water appears to have resulted in initial improvements during the study period. The authors show that the most significant change came about in terms of hardware: villages that received more drinking water investment now have more piped tap water and more access to water treatment infrastructure (disinfecting and filtering facilities). High rates of rural resident satisfaction with drinking water suggest the effects of drinking water investment are being felt at the village level.

To the authors’ knowledge, this is the first empirical study on drinking water investment over time in rural China using nationally representative data.

This study aims to determine preference and concerns regarding tap vs bottled water and recommendations to increase tap water use in a US Midwest university. The authors propose interventions to increase tap water use based on survey results.

The authors conducted an online survey of the community of a regional comprehensive university in the St. Louis metro-east region (Illinois, USA). They analyzed 781 responses using mixed methods, and developed recommendations based on community-based social marketing principles.

Black respondents reported higher bottled water use than White respondents. Undergraduate students reported higher bottled water use than faculty or staff. Most respondents were concerned about cost and environmental impact for bottled water and taste and water quality for tap water. Chemical and safety concerns were specific and location-focused for tap water only. Concerns were similar to Safe Drinking Water Act mandated public information, such as prior reports of lead (Pb) in campus drinking water. Tap water taste concerns may relate to proximity to the water treatment plant, resulting in high residual chlorine levels. To increase tap water use in this community, the authors recommend persuasive information campaigns, improvements to infrastructure and distribution that increase tap water convenience, more transparent public reporting on tap water lead levels, management of residual chlorine levels, and establishment of institutional norms favoring tap water over bottled water.

The authors evaluate barriers to drinking tap water across multiple environmental and social systems. The methods used in this study combine mixed methods analysis and community-based social marketing. The findings integrate respondent demographics and concerns, local water quality, local and national contamination events, campus-specific sustainability initiatives and barriers, and national drinking water regulations.

Bottled water consumption continues to break records worldwide and its environmental impact is often underestimated by the consumer. Many factors affect individuals’ choices to consume tap water and bottled water including perceived health risks and water quality. The University of South Florida (USF) has joined a nationwide initiative to become carbon-neutral, and reducing bottled water consumption was a chosen strategy. The purpose of this study was to assess the risk perceptions and drinking water choices of the USF-Tampa campus community.

A sample of 561 students, faculty and staff members responded to an online survey. The survey contained questions about the use of bottled water and tap water, reusable water bottles, risk perceptions and demographics.

The results revealed that certain groups – undergraduate students and ethnic/racial minorities (e.g. black/African American, Hispanic/Latino) – drank significantly more bottled water. Among political ideologies, Liberals drank the least bottled water. Females and minorities had significantly greater risk perceptions of the tap water on campus. Important perceived benefits were tap water being less expensive and better for the environment than bottled water. Important perceived barriers were poor tasting tap water and the desire for filtered water.

The findings suggest the need for public health campaigns to increase awareness of health, environmental and financial consequences of bottled water consumption. Such campaigns should aim to discourage bottled water and any potential increased sugar-sweetened beverage consumption while promoting tap water consumption.

The University of A Coruña (UDC) elaborated the SOSTAUGA project, aiming to reach a higher sustainable level of its water management. SOSTAUGA defined four priority points of action: the restoration of the natural courses on the campus; the adoption of an ecological sanitation model; the sustainable management of urban runoff; and the reduction of water consumption in university facilities and activities. This paper aims to present the methodology, the actions and the results related to the reduction of water consumption and the potential for the use of endogenous resources.

The agents involved were the senior management of the centres, the committees of the Green Campus, the scholarship students and the Office for the Environment. Several actions have been experienced: audit of water consumption in sanitary services; flow reduction in washbasin taps by means of valve adjustment (and repair of the valves when necessary); replacement of tap aerators with other more eco-efficient ones; replacement of faucets; introduction of dual-flush (DF) in cisterns; and information to users (eco-label).

Water audit reached 68% of the total number of washbasins and tanks in the UDC. Efficient aerator installation covered 16% of taps and valve adjustment covered the further 33.5% and provided flow reduction of 42%. Another 20% of valve units required repair. The current situation in toilets combines tankless flush valves and cisterns with single flush mechanisms. The introduction of DF mechanisms was assessed and proposed. The cost of these actions was very low, as evidenced by the investment return period while showing a high potential for user awareness.

Both from the environmental (water saving) and from the economic and social points of view, this study shows that similar projects aimed at the efficient and rational use of water are applicable to the universities and other public and private schools, with potentially positive results on sustainability and people awareness.

This study seeks to find out if chronic exposure via drinking water to high doses of a mixture of metals found as contaminants in tap and bottled water sources can alter the systemic physiology of residents.

A case control study was designed, 18 subjects drinking mainly tap water as main group (group I) and 15 subjects drinking exclusively bottled water as control group (group II) for a minimum of two years. Cadmium, lead, chromium and iron concentrations in drinking tap and bottled water samples were measured. The effect potential of the same metals were evaluated by assessing liver and kidney functions and haemoglobin levels for the studied subjects.

Iron concentration was found to be significantly higher in drinking tap water samples compared to bottled. Chromium, lead and iron were significantly higher in blood samples of group I subjects compared to the control group. Blood creatinine levels were positively correlated with that of chromium and cadmium of group I; and chromium levels of group II. Urea levels was positively correlated with lead levels of group I. Haemoglobin was positively correlated with iron blood levels of group I and negatively with lead levels of group II. No appreciable changes were found in the blood clinical markers of the liver functions of either group.

This study gives a concise idea about the higher level of some heavy metals in tap water compared to bottled and how heavy metal contaminants in drinking water may affect kidney function and haemoglobin level of consumers.

The purpose of this study was to identify how to reduce bottled water use on our campus, given that the majority of students were bringing it onto campus from outside sources. Bottled water bans have been implemented on several college and university campuses in an effort to reduce the consumption of bottled water and the associated waste. Observations on the campus of Allegheny College demonstrated that while bottled water was being consumed, students were not purchasing those bottles on campus.

To identify methods to reduce bottled water prevalence on campus, alter negative perceptions of local tap water and create behavioral changes among student, an environmental science class surveyed the student body. Students were asked about their preferred type of drinking water and why they preferred one type to another, as well as additional questions about reusable bottle ownership and usage.

The data identified that disposable bottled water was most commonly consumed by first year students, with rates of use decreasing the longer students are on campus. Many students were concerned about the safety of tap water and did not like the taste.

As a result of this survey, Allegheny College has increased the number of filtered, bottle refill stations throughout campus and provides a high-quality, metal water bottle to all students upon beginning their first year. Students are also provided information about the safety of Meadville tap water, as well as the environmental and social benefits of choosing tap water over bottled water.

The market of bottled water is one of the largest in the world. Paradoxically, the consumption of water in plastic bottles is highest in countries rich in the potable tap water of excellent quality. This paper aims to gain a better understanding of the factors that foster or hinder the intention to use refillable water bottles by university students and to determine whether their study program played a moderating role.

Within the framework of Ajzen’s theory of planned behavior (TPB), this paper conducted this cross-sectional study to understand the influence of attitudes, norms and perceived behavioral control (PBC) on the intention to drink tap water from reusable bottles. Italian university students (n = 540) majoring in the hard (42.4%) or the soft (57.6%) sciences completed an anonymous self-report questionnaire.

For both groups, there was a significant association between attitudes and intention to use a refillable water bottle. The intention to drink tap water was also influenced by PBC among the hard science students, whereas among the soft science students the descriptive norm exerted a significant influence.

This is the first application of TPB, a well-established theoretical and methodological framework, to understand the intention of university students to drink tap water from reusable bottles. Within the framework of TPB, this study is the first to address this specific pro-environmental behavior and explore the potential moderating role of university studies programs, which proved significant.

Iodine content in drinking water is a reflection of the iodine level of rocks and soil of the region. Different water sources have different levels of iodine; this makes variability in concentration of iodine content. The present study was done to estimate the iodine content in drinking water from different water sources of Ramtek villages in Nagpur district identified with sporadic cases of endemic goiter. The paper aims to discuss these issues.

The water samples were collected from seven villages from Ramtek taluka, which included well, bore well and tap water. Water was collected in clean and dry glass bottles from each source from the entire villages under study. The analysis of the water samples was done by the method of Karmarkar et al.

Iodine content of water samples varied from 17.42 to 43.55 μg/l in tap water, 17.42-21.77 μg/l in well water and 8.7-37.02 μg/l bore well water. The mean iodine content was found to be highest (34.04±11.44 μg/l) in tap water, while bore well water and well water showed 20.46±14.16 μg/l and 19.59±3.07 μg/l, respectively.

The endemic area has been surveyed by the author – the data generated and analyzed – the findings of which are independently arrived. The study is helpful for students, academicians, independent researchers, and the government policy makers for their further research, policy formulation and implementation.

The purpose of this paper is to assess and monitor a sample of heavy metals, namely lead, cadmium and copper, in water treatment plants at Greater Cairo, Egypt, to assess the efficiency of water treatment plants for metals removal and to monitor lead concentrations in the distribution system.

Water samples were collected from two water treatment plants. In addition, randomly flushed tap water samples from different districts at Greater Cairo were analyzed for lead concentration. Other water quality parameters also were monitored in water samples.

The study indicated that for water treatment plant intake, the mean concentrations were 4.44, 0.38 and 5.54μg/l for lead, cadmium and copper respectively. However, the final effluent shows that the mean concentrations of lead, cadmium and copper were 2.0, 0.15 and 2.78μg/l respectively. The drinking water mean metals concentrations were below World Health Organization drinking water guidelines and the Egyptian drinking water standards. The results revealed that water‐treatment plants have a high efficiency for metals removal where lead, cadmium and copper concentrations were reduced by 54.9, 60.5 and 49.8 per cent respectively. On the other hand, as expected, the water treatment plant sludge showed high accumulation with metals in concentrations decreased in the following order Fe > Mn > Zn > Cu > Cr > Ni > Pb > Cd. The mean lead concentration was 9.5μg/l in tap water samples.

Water treatment plants have a high efficiency for metals removal; water treatment plant sludge contains high concentrations of metals and should be treated before discharge; lead contamination from the distribution system is well established and lead concentration in homes in studied areas were higher than concentrations in plant effluent.
