Staying Informed and Involved
Contact EPA or LDEQ with any questions or concerns regarding Bayou Bonfouca.
Are there risks at the site now?
Risks and pathways addressed by the cleanup include health risks from people ingesting or touching contaminants in soil, sediment and groundwater.
Prior to the cleanup activities, contamination from the creosoting operations resulted in about one and a half miles of Bayou Bonfouca becoming biologically sterile due to severe creosote contamination in bayou sediments and water. In the early 1980's when EPA was investigating the contamination in the bayou, exposure to creosote contaminated sediments and water caused second-degree chemical burns to divers, injured or killed aquatic animals and waterfowl, and posed a significant hazard to recreational users. However, EPA's cleanup at Bayou Bonfocua consolidated contaminated soils and bayou sediments under a protective cap. As a result, there is no longer an exposure pathway to contaminated soils or sediments. Institutional controls which prohibit the use of groundwater at and near the site prevent exposure to contaminated groundwater. Groundwater use restrictions will stay in place until the site's groundwater remedial goals are achieved.
Sampling and Monitoring Information
EPA and LDEQ continue to review the operation and maintenance of the groundwater pump and treatment system. The system extracts groundwater which is contaminated with creosote and removes the creosote from the groundwater. The creosote that is removed from the groundwater is stored onsite and disposed of regularly. Monthly operational reports for the groundwater treatment system are submitted to the EPA for review and comment.
