Environmental - Remediation We use innovative and cost-effective technologies to clean up sites that have been contaminated with hazardous or non-hazardous wastes. We work with consulting engineering firms to develop a risk-based assessment of a site, then develop recommendations for cleanup. We have experience implementing a wide array of remediation technologies, including:
- In-Situ stabilization delisting for heavy metals (8RCRA)
- Ex-situ excavation and disposal
- Liquid-Boot®
- Engineering controls for pollution containment
- Steel or HDPE Piling cut-off wall
- Biopolymer slurry wall
- Bentonite/Clay barrier walls
- Geo-Composite Liner (GCL)/HDPE Liner/Cap construction, Installation, and landfill cover material
In-Situ Stabilization delisting for heavy metals (8RCRA) In this process, the Environmental team uses chemicals that react with heavy metals, binding them and keeping them from leaching out of soil. It is often used with Toxicity Characteristic Leaching Procedure (TCLP) testing. The process involves excavating soil, mixing the appropriate blends of chemicals with the excavated soil, and then backfilling the soil into the excavated site. Ex-situ excavation and disposal This process involves excavating contaminated soil, disposing of it at an approved landfill, and backfilling the excavation site with clean soil. The Environmental team can:
- Identify disposal sites
- Identify backfill sources
- Complete excavation, loading, backfill, compaction (hog and haul)
Liquid-Boot® LIQUID-BOOT® is manufactured and licensed in Ohio to Performance Environmental by LBI Technologies of Santa Ana, California. The cold-spray application of LIQUID-BOOT® creates an elastomeric liquid-impermeable membrane that can be used as a liner for Brownfields sites. The LIQUID-BOOT® membrane is a NSF/ANSI 61 approved, water impermeable liner. A membrane formed using LIQUID-BOOT® is also gas and vapor impermeable, making it a nearly perfect gas/vapor membrane adaptable to Brownfields needs. Engineering controls for pollution containment These remediation techniques allow the contamination to be stabilized and treated on-site. Steel or HDPE Piling cut-off wall Typically used to create an impermeable groundwater flow barrier, a steel pile cutoff wall also lends structural support to surrounding excavation activities. Performance Environmental will install steel or HDPE piling cut-off walls within 50 feet of the surface. Biopolymer slurry wall Performance Environmental excavates a narrow 2-3' trench and adds a biopolymer solution that creates a slurry, then backfills with clean soils or engineered controlled fill. This will minimize soil disposal issues on a project and allows for installation of groundwater recovery equipment. Bentonite/Clay barrier walls At many sites, the natural clay soil found throughout Ohio can be mixed with Bentonite to create a clay barrier that keeps contaminants from migrating off-site. Performance Environmental specializes in clay barrier wall and cell cap construction that provide a 10-7 impervious permeability level groundwater barrier. Geo-Composite Liner (GCL)/HDPE Liner/Cap construction, installation, and landfill cover material Used in capping and containing landfills, this process installs a High Density Polyethylene Liner (HDPE) to separate contaminants from surrounding soil and water. The Environmental team excavates a site and then uses certified HDPE welders on site to weld a liner of 30-60 mil plastic sheeting to fit the disturbed cap. A cap of the same material completes the process, completely sealing off the contaminants from surrounding soil and water. |
