Pesticides in the Nation’s Streams and Ground Water:
A Decade of Assessments Provide Information for Future Protection
Friday, March 3, 2006
9:30 am – 11:30 am
2318 Rayburn House Office Building
The U.S. Geological Survey’s National Water Quality Assessment
Program (NAWQA) will release a report documenting its nationwide
assessment of pesticides in streams and ground water from a decade of
monitoring and analysis. The report will be released at this briefing
and available for briefing attendees.
The USGS assessment provides the most comprehensive national-scale
analysis to date of pesticide occurrence, concentrations, and potential
for aquatic life, and wildlife. Among the major findings are that
pesticides are frequently present in streams and ground water, were
seldom found at concentrations likely to affect humans, but were found
in many streams at concentrations that may have effects on aquatic life
or fish-eating wildlife.
The assessment also begins to examine two important topics with
implications for the future—prediction of pesticides in unmonitored
areas and long-term trends.
USGS findings can be used to help guide and inform state and
national regulations and policies for water-quality protection, such as
those currently being deliberated in the 2007 Farm Bill. For example,
the science-based insights can help decision makers better anticipate
the types of pesticides most likely to affect water quality in urban
and agricultural areas, and improve investments in water-quality
monitoring and management across the Nation’s diverse environmental and
pesticide use patterns.
- Robert Hirsch, USGS Associate Director for Water,
will describe the elements of the NAWQA design and significance of
NAWQA’s studies, providing a context for the pesticide findings.
- Bob Gilliom, NAWQA Pesticide Synthesis Team Leader, will present key findings and implications.
- Jim Jones, Director, Office of Pesticides of the U.S. Environmental Protection Agency (EPA), will
present implications of the findings and collaborative efforts by EPA
and USGS to enhance the science base for EPA policy decisions.
The briefing is cosponsored by the Water
Environment Federation and the Environmental and Energy Study Institute
in cooperation with the U.S. Geological Survey.
The briefing is free and open to the public. No registration is required.
