EPA Superfund Site

LOUISIANA ARMY AMMUNITION PLANT

LA | EPA ID LA0213820533

Human exposure is under control

About this site’s exposure pathways: As of August 2023, there is insufficient data to determine the human exposure status at the Louisiana Army Ammunition Plant Superfund site. EPA identified an area of the site that includes residential land use with unknown potential for vapor intrusion into indoor air from volatile groundwater contaminants of potential concern. This residential land use affects the assumptions used during the time the remedy was originally selected. The activities planned to make the human exposure evaluation include completion of an evaluation, using multiple lines of evidence, to assess the potential indoor air vapor intrusion pathway for industrial and residential land use at areas exceeding the Vapor Intrusion Screening Level and to determine if any mitigation or remedial measures are warranted.

Data limitations: Proximity to a Superfund site boundary does not mean your property is contaminated. EPA site boundaries show the area designated for cleanup, not the full extent of contamination. Groundwater plumes can extend beyond site boundaries. This tool shows publicly available EPA federal data.
