Search Superfund Site Information
In 2014, the Superfund Program implemented a new information system, the Superfund Enterprise Management System (SEMS). Efforts to migrate data to SEMS and to enhance data quality control are now in the final stages. The Program will continue to rely on the final CERCLIS data set (dated November 12, 2013, which reflects official end of Fiscal Year 2013 Program progress) for public reporting until a complete and accurate SEMS data set is available. The current estimate for refreshing the content on this page is April 2015.
ILLINOIS CENTRAL RAILROAD COMPANY'S JOHNSTON YARD SUPERFUND SITE
The below list only includes contaminants identified as contaminants of concern (COCs) for this site. COCs are the site-specific chemical substances that the health assessor selects for further evaluation of potential health effects. Identifying contaminants of concern is a process that requires the assessor to examine contaminant concentrations at the site, the quality of environmental sampling data and the potential for human exposure.
