According to data from the California Environmental Protection Agency (EPA), Coronado, Camp Pendleton and Barrio Logan have the highest density of hazardous waste facilities and generators in San Diego.
Every census tract in San Diego is assigned a hazardous waste score by the California EPA in order to determine the areas most affected by pollution.
The San Diego Union Tribune has more information:
According to the California EPA, hazardous waste facilities are often located near poorer neighborhoods and communities of color. A 2011 study of 82 hazardous waste treatment, storage and disposal communities in Los Angeles County found that the communities most affected by the facilities are primarily working-class and ethnic minority populations living near industrial areas.
Other studies have found health effects, including diabetes and cardiovascular disease, are associated with living near a hazardous waste site.
Data show the rate of heart-attack-related emergency room visits in Coronado from 2011 to 2013 is 1.7 per 10,000 people. Camp Pendleton has a rate of 4.5 and south Barrio Logan has a rate of 5.4.
