Calcasieu Estuary Initiative
Site Description and History
The Calcasieu Estuary includes the area of the Calcasieu River from northern Moss Lake to the salt water barrier at Lake Charles. The estuary is an an industrialized area where several petrochemical and agrochemical plants manufacture and process diverse products. These chemical manufacturing and petroluem refining companies first appeared during the early 1920s with the discovery of nearby petroleum and gas reserves. Access to water transportation enabled the industrial base to suport more than ten major petroleum refining and chemical operations that produce a wide range of industrial chemicals, petroleum products, and commercial feedstocks.
In March 1999, EPA decided to conduct a Federal lead Remedial Investigation and Feasibility Study to evaluate the sediments in Calcasieu Estuary. EPA has divided the study into four areas: Bayou d'Inde, Bayou Verdine, Upper Calcasieu River (starting with the salt water barrier) and Lower Calcasieu River (ending at Moss Lake).
The
principal pollutants in the area are listed below. Follow the IRIS link
to EPA's Integrated Risk Information System. IRIS is a database of human
health effects that may result from exposure to various substances found
in the environment.
