II. Background

On a biannual interval, an Exposure Modeling Public Meeting is held for presentation and discussion of current issues in modeling pesticide fate, transport, and exposure of risk assessment in a regulatory context. Meeting dates and abstract requests are announced through the “empmlist” forum on the LYRIS list server at https://lists.epa.gov/​read/​all_​forums/​.

III. How Can I Request to Participate in this Meeting?

IV. Topics for the Meeting

Topics for the meeting will include presentations related to ground water modeling and pesticide modeling refinements in agricultural and urban environs. Specifically, presentations will include the following:

• Prospective groundwater monitoring studies and their utility for leaching model development.

  • Design and testing of a process-based groundwater vulnerability assessment (P-GWAVA) system.
  • Screening approaches for predicting pesticide concentrations in groundwater.
  • Using modern watershed and cropping data for estimating percentage crop treatment.
  • Comparison of models for estimating the removal of pesticides by vegetative buffer strips.
  • Advances in modeling urban/residential pesticide runoff.
