COMANCO Caps Landfill for Mississippi Superfund Site: Delivering long-term environmental remediation with advanced geosynthetics installation
COMANCO recently reached the final stages of remediating a Superfund site in Southeast Mississippi, delivering another safe and efficient geosynthetic installation to protect surrounding communities and the environment. This project involved capping a former industrial site that carried decades of environmental challenges. After years of planning and design changes, COMANCO Superintendent Carlos Garcia and his team mobilized last month. They completed the liner, GCL, and ClosureTurf® installation in just over a month, with support from KEMRON. Despite weather challenges, the crew maintained momentum, ensured material integrity, and is now finalizing sand grooming to complete the closure.
Materials Installed
COMANCO deployed and installed multiple geosynthetic materials to finalize this complex closure system, including:
- Watershed Geo ClosureTurf® System – featuring AGRU 40mil textured LLDPE geomembrane and engineered turf – both over 300,000 SF installed.
- CETCO BENTOMAT® GCL – over 300,000 SF installed
- SKAPS Geocomposite Vent Strips – more than 2,000 LF installed
These advanced materials provide long-term stability, erosion control, and a sustainable final cover solution for the Superfund site.
Building on COMANCO’s Safety Culture
A highlight of this project was the opportunity for seasoned crew members to mentor newly hired employees. Carlos and his team continued COMANCO’s strong safety culture established on prior projects, reinforcing the importance of planning, communication, and adapting to environmental conditions like heavy rain. The result was an efficient installation completed with zero safety incidents.
Tackling Historic Site Challenges
The site itself presented unique challenges due to a history of wood-preserving operations spanning several decades. Past practices left residual impacts in the soil and surrounding areas, requiring specialized containment measures. COMANCO’s expertise in geosynthetic systems allowed for a safe, lasting solution that helps prevent future risks while stabilizing the land for long-term protection.
Positive Impact
The completed cap ensures that residents and businesses in the surrounding area remain protected. Local water supplies remain safe, and the site has been stabilized to prevent further contamination. This project demonstrates COMANCO’s commitment to delivering turnkey environmental containment solutions that protect both people and the environment.
