RIVER AREA OF CONCERN - GRAND CALUMET (EPA) --
Grand Calumet River Area of Concern, 2008
In an effort to clean up the most polluted areas in the Great Lakes, the United States and Canada committed to working with
State and Provincial governments to develop Remedial Action Plans for designated Areas of Concern (AOC) in the Great Lakes Basin.
Currently there are 26 AOCs wholly within the United States and five that are shared by both the United States and Canada. This
shapefile provides a polygon boundary for the Grand Calumet AOC in Northern Indiana. In developing the polygon boundary,
the description of each AOC provided by EPA was used as a starting point for collecting basemap information to aid in the delineation
of each boundary.
The main use of the delineated AOC boundaries is for EPA and State governments to locate those sites listed on the National
Priorities List or other sites that are in close proximity or may have contributed to the pollution within each AOC. These
analyses are completed on a relatively small scale of the areas in and around each AOC. Attributes only include the AOC name
and the predominant state in which the AOC is located. The boundaries should not be used for large scale, high resolution mapping
These data were obtained from the Great Lakes Areas of Concern Web site of the U.S. Environmental Protection Agency (EPA)
