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.

Redevelopment Activity

Today, the cleanup efforts have restored over a mile of the Bayou for aquatic life and recreational and public reuse. A boat launch, which was constructed during the site's cleanup in the 1990s, is now a public boat launch which provides boater’s access to Bayou Bonfouca.  The former site owners donated the prime waterfront property to the City for redevelopment. The site now houses the City’s public operations offices and other city services. The City also coordinated with EPA and LDEQ to develop community green space and a public park, now known as Heritage Park. The park includes playgrounds, picnic areas, walking/jogging paths, restrooms and a large gazebo for performances and community gatherings.
 
In 2012, the City of Slidell received a $1.5 million Boat Infrastructure Grant (BIG) to promote boating access along Bayou Bonfouca near the site. Several years of coordination among the City, LDEQ and EPA has paved the way for the “Slidell Municipal Marina at Heritage Parkt”. A ground breaking for the marina project was hosted by the City in April 2017 and marina opened to the public in May 2018. .The Slidell Municipal Marina adds fixed and floating docks to Heritage Park and.includes65 new boat slips,s, piers, new sidewalks and more to encourage recreational boating on Bayou Bonfouca.
