Where It Comes From
Applied to soil as pellets or granules for non‑selective vegetation control on rangelands, rights‑of‑way, and some crops [1][2].
How You Are Exposed
Mixing and applying products, contacting treated soil or dust, spray drift, and drinking private well water where it has leached [1].
Why It Matters
Short‑term exposure may irritate eyes/skin or cause nausea if swallowed; animal studies show liver and body‑weight effects at high doses; groundwater risk drives regulation [1][2].
Who Is at Risk
Pesticide applicators and workers; people using shallow or sandy‑soil private wells near treated areas; infants, children, and pregnant people [1][2].
How to Lower Your Exposure
Follow label directions and wear protective gear; keep kids and pets off treated areas; prevent runoff; test private wells; use alternative water if contamination is found [1].
