Several brands of bottled water contain concerning levels of arsenic contamination, according to an investigation by Consumer Reports.

The worst offenders in the report were Starkey, a brand owned by Whole Foods and marketed as water in its "natural state," and Penafiel, owned by Keurig Dr Pepper and imported from Mexico.

Samples of Penafiel tested by CR had arsenic levels that averaged 18.1 parts per billion, well above the federal allowable limit of 10ppb set by the Food and Drug Administration. Testing of Whole Foods' Starkey Water revealed levels at or just a smidge below federal limits, with results ranging from 9.48 ppb to 10.1 ppb.
