bc-logo-block.jpg

PROJECT SUMMARY

Bluff City Materials, Inc., through its environmental division. Abbott Constructors, Inc., was contracted by Lane Construction, Inc. to remediate a 2.5-acre wetland contaminated with petroleum/tar.  The site, owned by the MWRDGC, was impacted by on-site migration of heavy marine bunker fuel into the wetlands.

The scope of work included:

  • Site preparation and site clearing and grubbing

  • Installation of coffer dams to control groundwater and petroleum infiltration

  • Excavation, stabilization, and staging of contaminated soil and sediment

  • Transportation and disposal

  • Water treatment

  • Wetlands restoration

 

Over 2,000 cubic yards of contaminated sediment and soils were excavated at the site.  In addition, over 100,000 gallons of petroleum and contaminated water were collected for treatment.  During the initial excavation stages of the project, BCM/Abbott had to design and construct a hydraulic barrier upgradient to prevent significant infiltration of petroleum and contaminated water into the active excavation site.  The clay barrier was implemented allowing the project to proceed.  BCM/Abbott was able to use beneficially reuse soil for backfill during the course of the project.  This allowed for project savings.
