Synthetic Polymer Contamination in Bottled Water

Back to Resource Library

Scientists test for microplastic contamination in 11 globally sourced brands of bottled water, purchased in 19 locations in nine countries. Of 259 bottles, 93% show clear signs of microplastic contamination. Fragments of microplastic were the most common type detected. A small number of particles showed chemical presence of industrial lubricant chemicals. Data suggests the contamination is at least partially coming from the packaging and/or the bottling process itself. The researchers found roughly twice as many plastic particles within bottled water as compared to tap water on average.
