CONTAMINATION EXTENT REPORT AND PRELIMINARY INJURY EVALUATION FOR THE CALCASIEU ESTUARY Prepared for: Damage Assessment Center National Oceanic and Atmospheric Administration Silver Spring, MD William Conner, Contracting Officer's Technical Representative Prepared by: Mark S. Curry, Michael T. Huguenin, Aaron J. Martin, and Todd R. Lookingbill Industrial Economics, Incorporated 2067 Massachusetts Avenue Cambridge, MA 02140 Contract 50-DGNC-1-00007 Task Order 56-DGNC-6-50107 June 16, 1997 FOREWORD This document reviews chemical contamination within the Calcasieu Estuary and fulfills the requirements of NOAA Task Order 56-DGNC-5-50107. The report consists of three major components. Part I presents the Resource Characterization. This section of the report assesses the overall extent of chemical contamination within the surface water, sediment, and fish and shellfish of the Calcasieu Estuary. Part II presents the Facility Review, which inventories the manufacturing processes, waste water treatment systems, and waste management practices of nine major industrial facilities within the Calcasieu Estuary. Finally, Part III contains the Injury Evaluation and Contaminant Review. This part of the report identifies contaminants that have the potential to injure the natural resources of the Calcasieu Estuary.
