Potable water. Consumption preferences among the population of Mures County, Romania

Water covers 75% of the Earth's surface and is essential for drinking, hygiene, agriculture, and industry. An individual requires roughly 5 liters daily to survive in moderate climates with minimal physical activity. Globally, about 4 trillion cubic meters of freshwater are consumed annually, yet drinking water distribution and consumption vary significantly. Consumer preferences, such as tap versus bottled water, have implications for public health and sustainability. Objective: This study aimed to evaluate drinking water consumption behaviors in Mure? County, Romania, focusing on preferred water sources and influencing factors. Methods: A cross-sectional survey of 1,310 adults, customers of the regional water supplier, was conducted through an online questionnaire assessing water sources, consumption habits, expenditures, and quality awareness. Tap water and popular bottled waters were analyzed for quality differences using statistical tests. Results: The majority of respondents (61%) bottled water, while 37% chose tap water; 15% consumed both. Tap water was mainly used for cooking (89%) and washing (93%). Many respondents (59%) spent an additional 10–50 RON monthly on bottled water. Younger adults favored bottled water. Conclusions: Although tap water met safety standards, bottled water remained popular, suggesting a need for public awareness initiatives promoting sustainable tap water usage.
