Mountain Valley bottled water tested clean with no detectable heavy metals, despite past allegations of arsenic contamination.

“When we tested Mountain Valley for contaminants, it was very clean. It did not have any detectable heavy metals. There's a story behind this, though. There's a pending class action lawsuit against Mountain Valley for two things. There's a test from 2019 that found arsenic at 1.1 parts per billion in Mountain Valley, and there's a test from 2025 that found.16 parts per billion of arsenic in Mountain Valley.”
