The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) was originally approved by US Congress in 1988 and it requires review and registration of both new and older pesticides. Since that time, many tools and versions of models have been developed by US EPA. This presentation will examine the changes in estimated environmental concentrations (EECs) and estimated drinking water concentrations (EDWC) over 25 years. This will include the impact in EECs and EDWCs from Piranha (PRZM-EXAMS) and SCI-GROW to PWC2.001. The affect to EDWCs with changing the drinking water scenarios will also be presented. Has it gotten more or less conservative over the years? What’s next?

Over 25 years of ecological and drinking water modeling for pesticide registration
