The report finds that seven low-income and minority-majority communities in northern New Castle County, Delaware, face significantly higher cancer risks and respiratory hazards from toxic air pollution compared to the state average and a wealthy, predominantly White comparison community. These risks are compounded by the high density of hazardous chemical facilities, Superfund sites, and Brownfields in these areas, particularly in Southbridge. The authors recommend stricter chemical safety regulations, mandatory fenceline monitoring, and the prevention of siting schools near dangerous facilities to mitigate these disproportionate environmental health burdens.

The report finds that seven communities in northern New Castle County, Delaware—characterized by higher poverty and proportions of people of color—face substantially higher cancer and respiratory health risks than the affluent, predominantly White community of Greenville and the state average. These risks are driven by toxic air pollutants, specifically formaldehyde and acrolein, and proximity to high-risk chemical facilities and contaminated waste sites. The document recommends stricter chemical safety regulations, enhanced fenceline monitoring, and the implementation of comprehensive health-impact assessments to address these environmental justice disparities.
