Public Perception of Drinking Water Quality in an Arsenic-Affected Region: Implications for Sustainable Water Management
Researchers surveyed residents in an arsenic-affected region of Serbia about their perceptions of tap water quality and found that most had a negative view, which closely matched actual water contamination levels. Over 43% of respondents purchased at least five liters of bottled water per week, and because Serbia has low plastic recycling rates, most of those bottles end up in landfills where they slowly break down into microplastics. The study highlights a cycle where water contamination drives bottled water consumption, which in turn contributes to plastic pollution.
