How long does 2,4-D stay in water?
The half-life of 2,4-D (the time it takes for half of the active ingredient to degrade) ranges from 12.9 to 40 days depending on water conditions. In anaerobic lab conditions, the half-life has been measured up to 333 days. After treatment, the 2,4-D concentration in the water is reduced primarily through microbial activity, off-site movement by water, or adsorption to small particles in silty water. It is slower to degrade in cold or acidic water, and appears to be slower to degrade in lakes that have not been treated with 2,4-D previously.

Depending on the type of waterbody treated and the type of plant being watered, irrigation restrictions may apply for up to 30 days. Certain plants, such as tomatoes and peppers and newly seeded lawn, should not be watered with treated water until the concentration is less than 5 parts per billion (ppb).
Is 2 4 D toxic to fish?
The ester formulations are toxic to fish and some important invertebrates such as water fleas (Daphnia) and midges at application rates; the amine formulations are not toxic to fish or invertebrates at application rates.

These organisms only recolonize the treated areas as vegetation becomes re-established.
