Crosby Mississippi DEQ Clean Up Site

Crosby Mississippi Streambank Restoration Remediation

Streambank Stabilization Project
Crosby Mississippi, April 2011

Abandoned creosote plant that stopped production in the 1940’s left a legacy of creosote leaching into an adjacent creek. A two step process of clean up and remediation of the streambank restored the natural bank and eliminated any leaching potential. Heavy, flashy storms battered the sandy banks eroding, in some areas, over 15 feet of streambank threatening a newly installed well head monitor.

Project Background
Dating to the turn of the century this creosote plant was used to make telephone poles and rail road ties. An extensive system of monitoring wells, removal of contaminated soils, and the use of organoclay to remove oil from water and to seal any potential of petrochemical leaching was utilized in this clean up of the site.


To revegetate the streambank and control continual erosion, Envirolok was utilized to face the highly eroded stream and protect monitoring wells that were installed as part of the clean up effort. PermaMatrix® Biotic Soil Amendment was installed over the Envirolok system to restore the biological function of the streambank. PermaMatrix is a combination of organics and biochar that greatly enhances the establishment and diversity of native plants. Sunmark environmental provided the Certified Installers to work with local contractors and was able to complete this job in 4 working days.
