The occurrence, movement, flux, fate, and effects
of agricultural chemicals in the U.S. are studied by the U.S. Geological
Survey's Research on Pesticides in the Environment (RPE) group.
Project researchers are identifying the sources of agricultural
chemicals (insecticides, herbicides, fungicides, fertilizers, and
others) to the environment and the factors that affect their dispersal
from point of application to groundwater, small streams, large rivers,
reservoirs, precipitation, and the atmosphere. The overall goal
of this research is to collect and synthesize agricultural chemical
related water-quality information to help resource managers, policy
makers, and the public develop agricultural management practices
that protect the region's water resources. This project is part
of the U.S. Geological Survey's Toxic
Substances Hydrology program, the recent activities of which
are described in a USGS
fact sheet.
