Plastic taints most bottled water, study finds
Microplastics in water can come from larger pieces of plastic that break down in landfills and oceans.
Fabrics such as fleece and nylon are made from plastic. When washed, they shed bits of plastic lint.
It travels from the wash water down household drains and eventually into rivers, lakes and oceans.
Other microplastic beads go in some toothpastes and skin-care products.
Once plastic bits go down the drain, it will wash into — and then out of — water treatment plants.
These facilities release their water into rivers and the ocean which is the source of tap water. Some of that water may move into groundwater, which some companies use for bottled water.
