Abstract:

INTRODUCTION This subtask of the Interagency Performance Evaluation Team IPET Task 9 project focuses on data mining and compilation for chemical results in four Louisiana parishes affected by flooding from Hurricanes Katrina and Rita Orleans, Plaquemines, St. Bernard, and St. Charles. The compounds of interest are arsenic, lead, benzoapyrene BaP and 1,1-dichloro-2,2- bisp-chlorophenylethylene DDE, selected by consensus as likely candidates because of availability of data following the flooding events Hurricanes Katrina and Rita and the chemical variability between them. Arsenic and lead, although both inorganic analytes, would behave differently based on soilsolution chemistry. Lead sorbs to soil as a traditional cation, whereas arsenic speciation AsIII or V would yield little sorption in reduced environments as AsIII, compared to increased sorption in the case of AsV being favored in oxidizing environments. AsV being favored in oxidizing environments. BaP is an organic polycyclic aromatic hydrocarbon which could be used to trace petroleum-impacted floodwaters. The pesticide DDE was selected because of its presence at superfund sites in the New Orleans area and historical production and usage in the area.
