Contaminated soil and groundwater remediation

GERMEN develops soil and groundwater remediation solutions based on site conditions and the nature of the contaminants. In situ and ex situ alternatives are evaluated to identify an appropriate treatment for each project.

Site characterization informs the selection of a technique and the intervention scope. Explore our bioremediation, Bio-Sparge and landfarming solutions and discuss the next step for your site.

Remediation: how to decide between in situ and ex situ alternatives

There is no single remediation technique that is best for every site. The appropriate alternative depends on contaminants, site conditions, the remediation objective and operational constraints.

01

What is the difference between in situ and ex situ remediation?

In situ treatment acts on the affected medium without excavation as the central step; ex situ treatment involves removing material so it can be treated under different conditions.

02

How is a remediation technique selected?

Selection starts with characterization and considers contaminants, geology, groundwater, land use, access, time and treatment objectives.

03

What information helps scope a project?

Location, site history, characterization results, contaminants of concern, affected media, operational restrictions and the remediation objective.

In situ vs. ex situ remediation

CriterionIn situEx situ
Where treatment occursAt the affected site, without excavation as the central step.After excavation or removal of affected material.
Operational factorCan reduce excavation but depends strongly on subsurface conditions.Allows greater process control but requires excavation and handling.
What defines suitabilityContaminant, geology, groundwater, access and treatment objective.Contaminant, excavation feasibility, logistics and final management.

Bio-Sparge Closed Loop System Benefits

  • Closed Circuit “ZERO” emissions by operating completely on-site and without emissions, we protect both the environment and local communities, avoiding the dissemination of pollutants.

  • By operating completely on-site, WITHOUT STOPPING operations and without emissions, we protect both the environment and the personnel operating in these areas, avoiding the dissemination of contaminants.

  • Control of Volatile Organic Compounds. They can present several risks, including high explosiveness, toxicity, and the generation of bad odors.

  • Integration of various technologies: Bioventing, Biostimulation, Bioaugmentation, Desorption, Closed Circuit, Biosparging, Vapor Extraction, Chemical Oxidation, Neutralization, etc.

  • Useful for Total Petroleum Hydrocarbons (TPH's), light, medium and heavy fractions; Polycyclic Aromatic Hydrocarbons (PAH's), Benzene, Toluene, Ethylbenzene and Xylenes

  • The only one in Mexico authorized for the treatment of:

    Oils, greases and lubricants (mineral, synthetic, soluble, hydraulic, vegetable, etc.)

  • Federal Permit: Authorization for the Treatment of Hazardous Waste: 11-V-77-18

  • Monitoring and control system. Our system allows monitoring of specific conditions, ensuring maximum safety in all types of industrial and population environments.

  • Compatible and flexible for each site. We adapt our system to the specific conditions of each site, ensuring maximum efficiency in all types of industrial and geographical environments.

"When the site does not allow for on-site treatment, our ex-situ bioremediation takes the solution off-site, to remediate the soil."

The fastest, most economical and flexible.

Benefits and Advantages of Ex-Situ Bioremediation

  • Rigorous Process Control: Allows precise control of treatment conditions, optimizing the effective degradation of contaminants.
  • Flexible Treatment Options: Can be designed to address a wide range of contaminants, including hydrocarbons, heavy metals, and persistent organic compounds.
  • Time and Cost Efficiency: Faster and more economical than in-situ methods, especially beneficial when quick action is needed to reduce environmental or public health risks.
  • Minimization of Environmental Risks: Reduces the risk of exposure and prevents the possibility of contaminant migration to unaffected areas.
  • Parallel Treatment Possibility: While ex-situ bioremediation is underway, the original site can remain active, which is particularly advantageous in industrial or construction zones where downtime is costly.
  • Regulatory Compliance: Ensures compliance with environmental standards, facilitating project approvals and adhering to best industry practices.
  • Soil Recovery and Reuse: Treated soil can be returned to its original location or repurposed elsewhere.
  • Reduced Visual and Noise Impact: Minimizes visual and noise disruptions for surrounding areas, improving the acceptance of remediation projects.
