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.
