Introduction
  • Geographical Information Systems (GIS) and Remote
    Sensing Imagery was used to identify possible
    releasers of effluent
  • made available through the development of a large
    dataset
  • points, lines, polygons, and vectors were
    developed and geographically projected to
    identify areas of interest.

  • Longest coastal monitoring program
  • Bivalve Sediment Collection
  • 300 active sites
  • 150 monitored contaminants

PBDEs
  • Toxic Chemical
  • Three Different Mixtures
  • Flame Retardants
  • Atmospheric Transport
  • Banned in California
  • EVERYWHERE!!!
  • Similar in structure to PCBs

Concluded SUCCESS
  • .but the proximity between mussel watch sites,
    and locations referenced as releasers of effluent
    and potentially polluted substances do not alone
    allow researchers to draw final conclusions that
    lead to the direct source of chemical
    contamination.

Future Applications
  • Water Quality Testing
  • GIS development
  • Localize Level
  • Government Partnership
  • Implementation of other Contaminants
