A Pilot Study of Post-Hurricane Katrina Floodwater Pumping on Marsh Infauna

Abstract

The Interagency Performance Evaluation Taskforce (IPET) is presently evaluating the performance of hurricane protection and damage reduction systems and consequences of structural failures to the New Orleans area following Hurricane Katrina. This evaluation includes determining environmental impacts to habitat and other biological resources. This report presents preliminary data concerning the effects of pumping of floodwaters on assemblages of benthic invertebrates in the immediate vicinity of the pumping stations in wetlands near Chalmette and Violet, Louisiana. Key points& What effect did Hurricane Katrina floodwaters have on benthic invertebrates close to the pumping stations in wetlands near Chalmette and Violet, Louisiana? Did floodwaters pumped on wetlands elevate salinity and contaminants? A pilot sampling study set out to answer these questions. Samples were taken at four pumping stations 3-1/2 months after Hurricane Katrina. Study results suggest
