Keurig Dr Pepper said it was withdrawing its Peñafiel brand unflavored mineral spring water products after reports that they contained high levels of arsenic.

The announcement, which was made on June 21, came three days after the Center for Environmental Health notified the company that tests showed the amount of arsenic in the water exceeded the level requiring a health warning under California’s consumer protection law, and two months after Consumer Reports found the amount exceeded the level set by the federal government.

A market withdrawal is voluntary and “occurs when a product has a minor violation that would not be subject to FDA legal action,” according to the United States Food and Drug Administration’s website.

Keurig Dr Pepper said its own independent water quality tests confirmed arsenic levels exceeding the F.D.A.’s bottled water standards of 10 parts per billion.
