Status of Hydrogen Sulfide in Bayou Corne AreaPrepared by Gary R. Hecox, Ph.D.

While low concentrations of hydrogen sulfide have been detected at some of the bubble sites, the concentrations are well below those that would pose a human health risk. Other than Relief Well #2, all hydrogen sulfide concentrations measured are consistent with the production of hydrogen sulfide caused by decay of trees and other vegetation in a swamp environment.
