PHASE IV GIS-BASED SEDIMENT QUALITY DATABASE FOR THE ST. LOUIS RIVER AREA OF CONCERN—WISCONSIN FOCUS - Overview of Sediment Quality Conditions in the St. Louis River Area of Concern

The Phase IV GIS-based sediment quality database for the St. Louis River AOC—Wisconsin focus represents a collaborative project between the St. Louis River Citizens Action Committee (CAC), WDNR, MPCA, and Exa Data & Mapping Services, Inc. in conjunction with their subconsultants from Premier Environmental Services, Inc. and Searay Environmental. For this phase of the database, additional sediment quality data from the Wisconsin side of the AOC were added to the database based on the procedures documented in the Phase III Quality Assurance Project Plan (QAPP; Crane 2005a), as well as in the Phase IV project team roles and responsibilities report (Crane 2005b). These data consisted of mostly benthic invertebrate community data from throughout the Wisconsin side of the St. Louis River AOC, as well as some pre-remediation sediment chemistry data from Hog Island Inlet and Newton Creek in Superior, WI. Post-remediation sediment chemistry data from this site were not available in time to add to the Phase IV database.
