Calcasieu Estuary Remedial Investigation

The Calcasieu Estuary Remedial Investigation Report presents the results of the site characterization study conducted from late 1999 to 2002. The report comprises 10 volumes of information in paper form. The report has been broken down into manageable files to accommodate downloading and viewing. Downloading the entire report may not be feasible for some users because of the size of the files. CD copies of the report are available at:
