Switch to a stainless steel or glass reusable water bottle. There are a lot of great options out there nowadays— insulated, non-insulated, sports top, straw top, open top, etc.

Recent studies show that bottled water contains 10 to 100 times more microplastics than previously estimated. A study published in January 2024 found that a typical liter of bottled water contains approximately 240,000 plastic fragments; 90% of these are actually nanoplastics (plastic pieces or fibers of 1 micrometer or less).

Scientists are still studying the health impacts of ingesting microplastics from bottled water and other sources. The micro- and nanoplastics may damage cells directly, and they may be harmful due to myriad toxic chemicals used in the manufacturing of plastics. According to the 2024 PlastChem project, about 16,000 chemical additives are used in making plastics (all types); 4,200 of these are known to be harmful to human health and/or the environment, and even more have not been studied.
