Indiana Lakeshore Air Toxics Screening
This website will serve as a repository of information for the Lakeshore Air Toxics Study and will be periodically updated as the project develops.
Purpose of the Study
The Northwest Indiana Lakeshore area is a highly industrialized, heavily populated area that includes Lake and Porter counties. The goal of this study will be to assess and properly depict potential risk associated with exposure to air toxics within northern Lake and Porter Counties. The secondary goal will be to enhance our knowledge using the latest risk characterization tools and techniques.
Sources and monitors within the Lakeshore Air Toxics Study Area
This assessment will:
- Create an air toxics inventory for use in a community scale modeling project
- Analyze data using Regional Air Impact Modeling Initiative (RAIMI)
- Calculate concentrations to determine:
- Excess cancer risk for each area
- Noncancer hazards
- Contributing facilities or mobile sources
- Contributing air toxics
- Compare results to:
- 2005 NATA
- Existing monitoring data
- Communicate results to the public
