Triazines and phenylureas are commonly used herbicides for controlling weeds in row crops. These herbicides and their degradation products have been found in samples collected from surface water, groundwater, and precipitation throughout the United States. Atrazine until recently was the most widely applied herbicide in the U.S. and is still a widely applied preplanting corn herbicide.
