If you’re on municipal water, you’re probably safe—your utility has to send you annual reports. But check those reports anyway, because sometimes they glance over “trace” levels like it’s no big deal. Private wells are where the real wild west begins, especially in areas with historic mining or volcanic soil (think the Southwest, New England, or the Midwest).
Quick reality check: don’t assume your “mountain spring” is pure just because it tastes crisp. That lovely taste could be arsenic’s cousin. Ironic, no? The only way to know is to test.
