From The New Orleans Times-Picayune / NOLA.com.  interesting bit is that the work comes from a religious group, the United Church of Christ Breath to the People project.

Louisiana, in spite of historically producing something around half of of the oil and gas in the US (if you include federalized offshore wells), and in spite of being a major hub of the petrochemical industry, Louisiana, particularly south Louisiana continues to be polluted and impoverished.  I tell people Louisiana isn’t a state, it’s a colony.

Report: These 4 south Louisiana chemical plants are top-10 ‘super polluters’ in the U.S.
