Environmental fate of triclopyr.
Triclopyr is nonpersistent in surface water. It has limited mobility and low to medium persistence in soil. Considering its adsorptive characteristics and that it dissipates via multiple pathways, such as photolysis, plant metabolism, and microbial degradation, its potential to leach to depth in soil and to contaminate groundwater is low. This conclusion is corroborated by field leaching and groundwater monitoring data, both derived from use areas in several states in the U.S. and sites directly near handling/mixing facilities. Even when detected in the groundwater, e.g., five reported detections in two states in the U.S., the highest concentration was well below the estimated HAL of the USEPA.
