Pilot Study of the Effects of Post-Hurricane Katrina Floodwater Pumping on the Chemistry and Toxicity of Violet Marsh Sediments

摘要

The Interagency Performance Evaluation Task Force (IPET) is investigating the environmental impacts of the future of the hurricane protection system around New Orleans, Louisiana, during Hurricane Katrina. The study is needed to determine the extent to which Katrina floodwaters in the New Orleans area may have impacted wildlife habitat and other biological resources iii surrounding areas. This technical note presents preliminary data regarding the effects of pumped floodwaters on sediment chemistry and benthic invertebrate toxicity near pumping stations that pumped floodwaters into marshes near Chalmette and Violet, Louisiana.
