Where It Comes From
Applied to lakes, ponds, reservoirs, and irrigation canals; breaks down in water over days to weeks [1][2].
How You Are Exposed
Drinking or using recently treated water; swimming/boating during or soon after treatment; work handling products or spray mists; pets/livestock drinking treated water [1][2].
Why It Matters
Short-term exposure can cause nausea, vomiting, diarrhea, stomach cramps, and eye/skin irritation; inhaling mist can irritate the nose and throat. Not classified as a cancer risk by major programs; acute effects are the main concern [1][2][3].
Who Is at Risk
Pesticide applicators; people using treated water bodies soon after application; children and pets [1][2].
How to Lower Your Exposure
Follow local notices and label waiting periods before swimming, drinking, fishing, or irrigating; use alternate water if your supply was just treated; keep pets/livestock away; wear gloves/eye protection when using products; rinse skin/eyes if contacted and seek care if symptoms occur [1][2][3].
