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.
