On September 17, 2008, EPA’s Office of Pesticide Programs, Office of
Water, Office of Research and Development, and Region 7 met with
Syngenta Crop Protection, Inc. on atrazine ecological stewardship
activities in Missouri.  Syngenta reported to EPA on its label education
efforts in two Missouri watersheds, where atrazine concentrations have
exceeded EPA’s levels of concern, as well as results from those
efforts.   Syngenta also reported on ecological monitoring results from
2004 to 2008 and its progress in adapting monitoring protocols to EPA
recommendations.  EPA reviewed with Syngenta deliverables and due dates
necessary to prepare for a May 2009 follow-up consultation with the
FIFRA Scientific Advisory Panel on the atrazine ecological monitoring
program.   At the end of the meeting, Syngenta presented results of GIS
research on slope and hydraulic conductivity that provides an additional
means of identifying water bodies vulnerable to atrazine contamination.
