Agricultural Chemicals
One of the focuses of the U.S. Geological Survey Toxic Substances
Hydrology (Toxics) Program is investigation of the fate and occurrence
of agricultural chemicals. Toxics Program agricultural chemical investigations
focus on characterizing the processes that affect dispersal of chemicals
in the atmosphere, ground water, and surface water; identifying persistent
degradation products; and developing methods to measure these compounds
in water samples at environmentally relevant concentrations. Results
of these investigations are used by government regulators, pesticide
manufacturers, farmers, water resource managers, and the public.
Toxics Program Projects studying agricultural chemical transport and fate in
regional or watershed settings:
