Remediation of contaminated sites

The Talantia team has expertise in the custom design of soil and water (groundwater and surface water) clean-up solutions and has led numerous projects at sites of varying size and complexity.  In each case, our speciality is to select the best technologies and combine them in order to obtain the most satisfactory results.

Our approach consists of tackling the contaminated site remediation challenge based on an in-depth analysis of alternatives for the purpose of selecting the most effective and worthwhile solutions whilst reducing waste generation. Talantia defines itself as a problem-solver.

Remediation work at a site may end up requiring significant investment.  For that reason, we believe it is essential to involve the client in the team so that they are able to understand the strategy proposed, the service that is being bought and participate in the process.

However, the mere design and implementation of a remediation system is not sufficient to clean up affected subsoil.  Ongoing monitoring of the clean-up process is also required in order to adjust the process based on the results obtained over time.  This avoids extending the duration of work, which could result in increased costs and frustrated expectations for the entire team.

Some of the “in situ”, “on-site” and “off-site” remediation techniques we have used at various sites include:

  • Soil Vapour Extraction
  • Air sparging
  • Groundwater pumping and treatment
  • Excavation and management of soil and waste
  • Biopiles
  • Soil washing
  • In situ chemical oxidation (ISCO)
  • In situ chemical reduction (ISCR)
  • Surfactants
  • Bioremediation


In addition, Talantia is in the process of developing applications that involve new treatment technologies in order to offer more complete, effective and affordable solutions to our clients.
