Area of Science:

  • Environmental Science
  • Environmental Modeling
  • Geographical Information Systems (GIS)

Background:

  • Trichloroethene (TCE) is a significant environmental contaminant.
  • Understanding contaminant fate and transport is crucial for watershed management.
  • Existing models often lack spatial resolution for complex environmental units.

Purpose of the Study:

  • To develop and apply a spatially resolved multimedia model for assessing TCE fate.
  • To evaluate TCE distribution and transport within the Passaic River Watershed.
  • To identify data gaps in environmental monitoring for improved modeling.

Main Methods:

  • Utilized publicly available GIS data, chemical release data, and monitoring networks.
  • Developed an unsteady-state multimedia model incorporating spatial resolution.

  • Modeled seven environmental media (air, water, sediment, soil, vegetation) and their sub-compartments.
  • Defined sub-watersheds as environmental units for spatial analysis.

    • Main Results:

    • Successfully demonstrated spatial representation of cross-boundary contaminant fluxes.
    • Assessed TCE fate and transport across 11 sub-watersheds within the Passaic River Basin.
    • Identified critical data gaps, including limited organic contaminant monitoring and non-uniform physical environmental data.

    Conclusions:

    • The developed spatially explicit multimedia model is effective for assessing toxic contaminant fate.
    • Sub-watersheds serve as effective environmental units for understanding contaminant transport.
    • Improved and standardized environmental monitoring data are essential for refining such models.
