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.

What this violation means

Atrazine is one of the most widely used herbicides in US agriculture, primarily on corn and sorghum. Spring runoff from farm fields creates seasonal spikes in atrazine levels in surface water sources across the Midwest. Long-term exposure is linked to hormone disruption and reproductive effects.

Recommended precautions

→Granular activated carbon removes atrazine — most carbon filters work.
→Reverse osmosis provides additional protection.
→Atrazine spikes are seasonal — utilities monitor quarterly averages, but acute exposure can occur in spring.
