What this violation means

Arsenic is a known human carcinogen that occurs naturally in groundwater across many parts of the United States, especially the Southwest and parts of New England. Long-term exposure even at low levels has been linked to bladder, lung, and skin cancer, as well as cardiovascular disease and developmental effects in children.

Recommended precautions

→Reverse osmosis filtration removes arsenic effectively.
→Distillation also removes arsenic — point-of-use distillers work for drinking and cooking water.
→Boiling does NOT remove arsenic. It actually concentrates it as water evaporates.
→If your well water has arsenic, test annually and treat at the point of entry.

Recommended precautions

→Reverse osmosis is the gold standard for removing uranium.
→Ion exchange systems work but must be sized correctly for uranium.
→If you live near former mining sites, test for uranium even if not required.
