The UIC School of Public Health (UIC-SPH) Public Health program partnered with the Electronic Visualization Laboratory (EVL) and environmental experts to develop this Proximity to Hazards Dashboard and a series of other visualization dashboards.These interactive dashboards use maps and data tools to help communities better understand environmental health concerns.
One of the underlying objectives of this dashboard is to enhance the visual communication of the distribution of environmental burdens and benefits in Cook County. Based on our interaction with the community all these years, we established that with a "nearby" design approach (e.g., address), the concept of proximity burden ceases to be an abstract construct concerning a potential exposure of a population within preselected boundaries (e.g., community area, block group, etc.). This proximity to the hazards dashboard places individual community members at the center of a cognitive frame. It provides an answer to a common question raised during our meetings: "which polluters are near my home?" (or the school of my children).
SPC utilizes the PHD tohelp identify and evaluate potential environmental hazards that may impact thehealth and safety of local communities. This tool allows SPC to betterunderstand nearby environmental concerns and assess potential risks associatedwith hazardous sources.
Through comprehensiveinvestigations, SPC evaluates site conditions to determine whetherenvironmental hazards are present and if they may pose ongoing risks to publichealth. These assessments provide valuable information to support regulatorycompliance, informed decision-making, and the development of effectivesolutions that protect communities and the environment.
TRI facilities were included as documented sources of hazardous emissions. Data from the USEPA TRI Basic Plus Database provided facility locations and information related to reported toxic chemical releases, including emission quantities and potential health concerns.
Major freight railroad hubs were incorporated due to their contribution to particulate matter pollution. Chicago contains eight major freight rail hubs, with six located in the Southwest region of the city. Data was collected from the U.S. Department of Transportation database.
Brownfield locations were included to identify properties where redevelopment may be impacted by the presence or potential presence of hazardous substances, pollutants, or contaminants. The dashboard utilized data from the USEPA’s “Cleanups In My Community” database to evaluate brownfield proximity and density.
Asphalt production and processing facilities were added due to concerns from Southwest Chicago communities regarding their proximity to residential areas. These facilities were identified by name and location to improve public awareness, with ongoing efforts to expand available information for asphalt facilities throughout Chicago.
