Where It Comes From
Spraying on non‑crop areas; runoff and leaching from treated soil; slow breakdown in soil and water [1][2].
How You Are Exposed
Drinking contaminated well water; touching or breathing dust/spray near treated areas; on‑the‑job mixing and application [1][2].
Why It Matters
High exposures can irritate eyes/skin and cause nausea or dizziness. In animals, repeated dosing affected liver and kidneys. Cancer evidence in humans is inadequate; regulators have not identified a cancer hazard from typical environmental exposures [1][2].
Who Is at Risk
Pesticide applicators; people using private wells near treated rights‑of‑way; young children; pregnant people; those with liver or kidney disease [1][2].
How to Lower Your Exposure
Keep children and pets off treated areas until dry; follow product labels and wear gloves, long sleeves, and eye protection when applying. If you have a nearby private well, test your water; consider NSF‑certified activated carbon filtration to reduce pesticides [2][3].
