Where It Comes From
Applied on farms; can reach streams and groundwater via runoff and leaching; breaks down slowly in soil and water [1][2].
How You Are Exposed
Drinking water in agricultural areas; residues on treated crops; skin/eye contact or breathing spray during application; drift to nearby homes [1][2].
Why It Matters
Short-term exposure can irritate eyes/skin; high-dose animal studies report effects on liver and blood. It is moderately persistent and mobile, so protecting water sources matters [1][2].
Who Is at Risk
Farmworkers and pesticide applicators; people living near treated fields; private well users in farming regions; pregnant people and children [1][3].
How to Lower Your Exposure
Rinse and scrub produce; peel when possible [4]. For private wells, test regularly and consider treatment; activated carbon or reverse osmosis can reduce many herbicides [3][5]. Follow label directions and wear protective gear when using pesticides; keep children and pets away from treated areas [1].
