Field and aquatic dissipation studies

Dissipation studies are crucial for the registration of agrochemicals.  Waterborne has managed numerous dissipation studies since 1996 with a variety of study designs.  Our scientists collaborate with reputable field cooperators across the US and Canada to conduct both terrestrial and aquatic field dissipation studies.  Our team provides everything from instrumentation support and data management to complete study management and regulatory reporting.

Our Terrestrial Field Dissipation Work

At Waterborne, we have conducted and managed numerous terrestrial field dissipation (TFD) studies following USEPA Guideline 835.6100. Each study conducted has been designed to meet regulatory guidelines such as the USEPA FIFRA Subdivision N Guidelines. We have additionally used a variety of study designs, pesticide application methods (e.g., broadcast, banded, multiple, aerial, and seed treatment), sampling techniques (e.g., soil, water, air, and crop) and crops covering all geographical regions of the United States and parts of Canada based on similar Ecoregions. Due to the diverse nature of studies, Waterborne has developed sampling techniques for a broad range of crops and innovative solutions for atypical sampling requirements, including:

  • Turf
  • Tomato
  • Cotton
  • Small grain
  • Sugar cane
  • Orchard
  • Rice
  • Corn
  • Tobacco
  • Soybean
  • Other vegetables
  • Treated Seeds

Waterborne works closely with Contract Research Cooperators (CROs) that have undergone vigorous prequalification inspections to ensure their capabilities of performing a compliant Good Laboratory Practice (GLP) study. Our diverse network of field cooperators allows us to place studies anywhere in North America.

Aquatic Field Dissipation

We know all about rice production and have performed numerous rice paddy aquatic field dissipation (AFD) studies (USEPA Guideline 835.6200) with seed treatment, ground and aerial applications at multiple locations in Arkansas, California, Louisiana, Mississippi, Missouri, and Texas. These studies generate real-world data for evaluating potential hazards of an agrochemical (including mobility and formation of transformation products of the parent compound) under actual use and environmental conditions. Additionally, these studies generate information relative to mechanisms of dissipation in various aquatic environments. 

Based on this experience, we’ve developed an environmental fate model (RICEWQ) specific to rice production that has been used throughout the world to address regulatory concerns.
