Providing Expert Advice and Water Quality Impact Assessments for Agriculture & Turf

The pesticide law, FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) and its regulations, constitutes a mature but complex environmental statute. It is difficult to achieve the burden of proof that there will be "...a reasonable certainty that no harm to any population subgroup will result from exposure to [pesticide x]." This goal is dictated by the Food Quality Protection Act (FQPA) of 1996. This effort requires the use of appropriate, valid, and often cutting-edge risk assessment methods, often including computer simulations models. In addition, ETS assists pesticide registrants by conducting ground water and surface water quality impact studies and risk assessments. These field and modeling studies can support pesticide registration at the federal and state levels, as well as internal corporate decision making.

• Sample Problems
• Agriculture: Evaluation of water quality monitoring results from cotton areas of an herbicide with complex environmental chemistry. Used PRZM-EXAMS model system for an insecticide applied to sugarcane, and a molluscicide applied to citrus and tomatoes.
  
  
• Industrial: Evaluation of potential water quality impacts of a once-through disinfectant proposed for Wastewater Treatment Plants (WWTP) using the CORMIX and EXAMS models.
  
  
• Turf: Presentations in 2002 and 2007 at EPA's Office of Pesticide Programs Environmental Modeling Public Meeting providing guidance on modeling potential turf pesticide impacts on water quality. Integrated evaluation of ground water, surface water, fish, sediment, and atmospheric modeling and monitoring related to reregistration of a turf fungicide.
