The soil around the Gowanus Canal might be so flammable you can set fire to it with a match, but a new solution to the problem of the canal’s toxic underbelly is being explored, according to an article in the Brooklyn Eagle.
Instead of dredging the muck out, the Army Corps of Engineers is considering covering the contamination with a clay-based seal called AquaBlock.
“If the canal is dredged from top to bottom, you’re talking tens of millions of dollars. To use a clay capping like this AquaBlock material, it would be in the single digits,” said one of the engineers.
