New Orleans’ Black Pearl neighborhood has spent the week trying to identify a white dust that settled over cars, trees and other outdoor surfaces. Residents have photos, a few theories and at least one freshly washed vehicle—but no confirmed answer. The Louisiana Department of Environmental Quality had not publicly identified the substance or its source as of Thursday.
Images sent to WDSU show a visible coating on a car and on a tree near Burdette and Benjamin streets. Phil Sandusky, who said he has lived in the neighborhood for decades, described the substance on the trees as dust, while Erin Constantine said she washed her car to remove it. The newsroom also received photos and videos from other viewers who noticed the same residue.
Residents Point Across The River To Westwego
Some viewers suspected the dust came from Cargill’s grain-processing operation in Westwego, across the Mississippi River. Cargill told WDSU that it is “committed to being a good neighbor” and maintains environmental controls and operating practices. That response does not confirm the plant caused the dust, and no agency has publicly made that connection.
The Westwego operation is a grain facility rather than a mystery industrial site conjured by neighborhood rumor. Older OSHA records identify the Cargill Westwego facility as a grain and field-bean merchant operation, but those records concern a closed 2012 inspection and do not establish the source of the current residue.
Officials Have Not Identified The Substance
New Orleans City Councilmember Aimee McCarron’s office told WDSU it was not aware of the issue, while the Louisiana Department of Environmental Quality had not responded to the station’s questions. That leaves residents with no official explanation for why the dust appeared or whether it came from a nearby industrial operation, weather event or another source.
For now, the Black Pearl has the least satisfying kind of environmental update: the dust is real, the cleanup is real and the explanation is still missing. Until officials or independent testing identify the material, the Cargill theory remains just that—a theory.
