A nonprofit environmental group says independent testing it commissioned found that two brands of bottled water have arsenic levels high enough to require a consumer health warning in at least one state.

The Center for Environmental Health (CEH) is talking about the levels of arsenic in Starkey Water, which is owned and sold by Whole Foods, and Peñafiel, owned by Keurig Dr. Pepper. Peñafiel is sold at Target, according to CEH, and USA Today reports it's also sold at Walmart.
