The article's primary focus is the failure of a government agency in the wake of the 9/11. The EPA's inadequate response to air pollution and subsequent public misguidance led to a multitude of public health issues. While the article does not explicitly detail the issues stated in this lawsuit, it does mention the EPA's failure to properly formulate and enact a plan to clean up materials released into the air.
The article addresses the inequities in public health by showing how millions of tons of dust from concrete and asbestos were kicked up into the air after the tower collapses of 9/11 and was then determined to be safe per the EPA. A lawsuit was filed against the EPA on behalf of schoolchildren required to attend school in buildings near the site of the collapse and forced to breathe in so-called safe air. Emergency response is not directly addressed however plans of mandating that the EPA pay for the cleanup process are mentioned.
