  • Soil remediation, one discipline within the broader scope of environmental remediation, is the process of decontaminating soil. RECON is an industry leader in soil and sludge stabilization and solidification.
  • A secant wall is used in deep foundations in situations where the surface soil layers are unstable.
  • Among the processes used in soil remediation, excavation and dredging are among the most common. The process involves extracting unrecoverable contaminated soil.
  • Secant pile walls are one of the most economical methods of creating effective water control barriers for building structural walls, top-down tunnels and dams.
  • Deep Soil Mixing is a in-situ soil improvement technology used to construct cutoff or retaining walls and to treat contaminated soils.
  • This sludge pond is a good candidate for bio remediation or stabilization.
  • RECON's excavator is capable of digging a slurry wall up to 100 ft deep. Slurry walls have been used for decades to provide cost-effective, long-term solutions for many groundwater control problems.
  • Soil remediation project using remote placement conveyor.
  • Driving concrete pile to strengthen and support structural foundations.
  • Slurry wall construction is used to create non-structural barriers (Cutoff Walls, Slurry Trenches), which are constructed underground to impede groundwater flow.

Bioremediation

 

RECON is an international leader in the development and application of bioremediation technologies. Our vast experience consists of both insitu and exsitu applications.

 

INSITU BIOREMEDIATION: Recon was the first contractor to develop and construct permeable reactive barriers (PRB) to bioremediate contaminated groundwater. Insitu technologies also include the deep soil mixing of oxygen releasing compounds (ORC) and other constituents designed to promote contaminant degradation.

 

EXSITU BIOREMEDIATION: Exsitu remedies include windrow composting, bioheap extraction, and landfarming. All of RECON's bioremediation technologies enhance indigenous microorganism growth to accelerate the degradation of organic contaminants. Our experience base includes both aerobic and anaerobic biodegradation. Depending upon project requirements enhancement of indigenous microorganism is completed with:

 

1. Enzymes

2. Surfactants

3. Nutrient addition

4. Compost

5. ORC

6. Acclimated microbes

 

Should up-front laboratory testing indicate a low native bacteria colony count, populations of microbes specifically acclimated for the waste stream are developed and deployed. Our field personnel continually monitor contaminant concentrations, pH, nutrient dosage and other parameters to ensure optimum degradation occurs. Additionally, RECON utilizes field equipment to ensure affected soils remain aerated or windrowed when inclement weather is approaching.
