When this is used, you cannot swim in the area for 24 hours. If you pull lake water, you cannot drink it for about a month. It could be longer. This includes water for coffee, cooking etc. You cannot shower in it for 24 hours. Scary?? I know people who wouldn't shower in it for the whole month. The towns have to arrange for an alternative water supply during the time the 2,4-D is in the water. If your well is within a certain distance from a treated area, you should not use your well. (50 feet maybe?) They say it doesn't hurt the loons, ducks or fish. But your dogs are not supposed to drink it. If you are growing vegetables, you cannot water them with it and I believe flowers also. Any other questions, class?
( I probably couldn't answer them.)
