Ground-water Sensitivity and Vulnerability to Pesticides in Utah

Front Cover

The U.S. Environmental Protection Agency is recommending
that states develop Pesticide Management Plans for
four agricultural chemicals – alachlor, atrazine, metolachlor,
and simazine – herbicides used in Utah in the production of
corn and sorghum. This report and accompanying maps are
intended to be used as part of these Pesticide Management
Plans to provide local, state, and federal government agencies
and agricultural pesticide users with a base of information
concerning sensitivity and vulnerability of ground water
to agricultural pesticides in Utah. We used existing data to
produce pesticide sensitivity and vulnerability maps by
applying a combined process-based and index-based model
specifically tailored to the Western United States using Geographic
Information System analysis methods. This is a first
cut at developing pesticide sensitivity and vulnerability
maps; better data and tools may become available in the
future so that better maps can be produced.
