Bottled water versus tap water Risk perceptions and drinking water choices at the University of South Florida

Purpose 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. Design/methodology/approach 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. Findings 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. Originality/value 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.
