In a survey last year, the association found that the average American drinks about a half-dozen eight-ounce servings of a water each day. Bottled water accounts for 2.3 of those servings.

Doing so would free up 60,000 to 65,000 gallons of water a month. The EWA says its board of directors is working hard to correct this problem as soon as possible.

Researchers found roughly 240,000 detectable plastic fragments in a typical liter of bottled water. Most of them were nanoplastics — particles less than 1 micrometer in size.
