Public Perception of Drinking Water Quality in an Arsenic-Affected Region: Implications for Sustainable Water Management
AI summary Read the abstract
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.
This work explores the relationship between water quality and public trust in their water supply, in an arsenic-affected region of Serbia. The results from an online public survey are presented and subjected to Pearson’s correlation, cluster analysis, and principal component analysis. In general, survey respondents in settlements with known arsenic issues had a poor opinion on the quality of their tap water. This poor opinion was underlined by their consumption of bottled water, with more than 43% of responders purchasing at least 5 L of bottled water a week. In addition to the great economic cost, the relatively low plastic recycling rate in Serbia means that this also has a very negative effect on the environment, as most of the plastic bottles are sent to landfill, to degrade slowly into microplastics, whilst leaching a variety of chemical contaminants into the surroundings. In the area studied, the poor public opinion of the water quality is a realistic reflection of water at the tap. Although significant, the additional environmental pollution from bottled water consumption should nonetheless be of secondary consideration in comparison to the health risks associated with chemical contaminants in the study area, with local waterworks requiring significant financial assistance if they are to meaningfully improve tap water quality.

Analytical Review of Microplastics Occurrence in Bottled Water, Tap Water, and Wastewater Treatment Plants
AI summary Read the abstract
This review analyzes microplastic contamination across bottled water, tap water, and wastewater treatment plants using data from studies worldwide. Researchers found that microplastic levels in drinking water are closely tied to the water source and that packaging type significantly influences contamination, with glass bottles recommended over plastic. The study emphasizes the need for improved water treatment technologies and greater public awareness about microplastic exposure through drinking water.

Comparing in-home and bottled drinking water quality: regulated and emerging contaminants in rural Central Appalachia
AI summary Read the abstract
Researchers analyzed regulated and emerging contaminants including bacteria, inorganic ions, PFAS, and microplastics in 23 in-home, 4 roadside spring, and 36 bottled drinking water samples from rural Central Appalachia. They found that coliform bacteria and elevated sodium levels occurred in 52% of home water samples, while PFAS and microplastics were detected across all water source types, complicating the assumption that bottled water is consistently safer than in-home supplies.
