The Kerr-McGee Chemical Corp � Columbus site is located in Columbus, Mississippi. It includes the area where Kerr-McGee Chemical and its successor, Tronox Incorporated (Tronox), operated a chemical manufacturing facility from 1928 to 2003. EPA placed the site on the Superfund program�s National Priorities List (NPL) in 2011 because of contaminated groundwater, sediment and soil resulting from facility operations. EPA and the Mississippi Department of Environmental Quality (MDEQ) have taken steps to clean up the site in order to protect people and the environment from contamination. EPA conducted short-term cleanups in 2010 to remove highly contaminated soils from Hunt Intermediate School, Miranantha Faith Center and a nearby residential property on Moss Street. EPA is conducting an extensive investigation to identify all site-related risks to people and the environment. Most residents and businesses nearby use the public water system for drinking water. As part of its investigation, EPA plans to survey residents and businesses to make sure no one is drinking water affected by groundwater contamination. EPA has also taken several steps to keep the community informed and involved in site-related activities.
