Environmental Processes and Engineering Division, EP

Published Oct. 6, 2016


The Environmental Processes and Engineering Division (EPED) conducts research, development, technology transfer, and technical support in assessment and remediation technologies essential for the understanding and management of watersheds and associated aquatic ecosystems. Assessment technology research and development ranges from custom chemical analysis to field scale experiments utilizing a complex of unique laboratory and engineering facilities to simulate and/or model field conditions. Approaches typically follow the environmental risk assessment paradigm of evaluation of exposure and effects of stressors on endpoints of concern. Results of these investigations support the development of environmental quality modeling technologies for surface and groundwater environments that are used for the simulation of management or remediation alternatives. These assessment and modeling technologies also support the research and development of remediation technologies, which utilize civil and environmental engineering approaches to develop pilot and field scale engineering systems for cleanup and remediation of contaminants. Training with these developed technologies is also provided to the Corps of Engineers, Army and other Federal and nonfederal agencies.


  1. Apply research and development to chemical analytical methods for routine and specialized analysis of chemicals in soil, water, and biological media.
  2. Provide chemical analysis quality control for the Corps' water quality and Hazardous, Toxic, Radiological Waste (HTRW) missions.
  3. Apply research and development to physical, chemical, and microbiological processes associated with watershed and aquatic ecosystems.
  4. Apply research and development to ecotoxicological processes and methods to develop more quantitative evaluations of effects of contaminants in the environment.
  5. Apply research and development to water quality and contaminant models to provide numerical models for simulation of physical, chemical, and biological processes in aquatic ecosystems.
  6. Apply research and development to civil and environmental engineering solutions to cleanup and remediation of contaminants in soil, water, and groundwater. Provide environmental engineering research, development, evaluation, consultation, technology transfer, and training support to the Corps, other Department of Defense (DoD) elements, and non-DoD agencies.
