Before starting a reclamation, it is necessary to conduct preliminary investigations to evaluate the level and type of contamination present on the site. This may include samples of soil, of groundwater, of air and living organisms to determine the presence and the extension of contaminants.

Based on the information collected during the preliminary investigations, a detailed remediation plan is developed. This plan identifies the most appropriate strategies and techniques to remove or reduce contaminants in the contaminated site. Planning phase also includes cost estimation, time evaluation and the management of the resources necessary for the reclamation.

Remediation may require the application of different technologies and techniques depending on the type and the extension of contamination. These may include soil remediation through soil washing, thermal incineration or extrusion, physical removal of contaminated materials, the use of bioremediation or phytoremediation processes, as well as the application of containment barriers or extraction systems of groundwater.

During remediational operations, contaminated waste is generated and It must be managed safely and effectively. This requires contaminated materials identification, and the correct separation and disposal of them, in accordance with current environmental regulations. It is essential to ensure that waste is treated and disposed at authorized facilities, approved by the current regulations.

During and after remediation, it is necessary to monitor the effectiveness of the actions taken and verify compliance with the established remediation criteria. This may include monitoring levels of residual contamination, analysing groundwater, soil or air, as well as checking the performance of the technologies used. Monitoring and verification are essential to ensure that the site has been fully remediated and It is safe for future use.

Remediation must be conducted in accordance with applicable environmental laws and regulations. This may include laws for the remediation of contaminated sites, regulations for waste management, guidelines for monitoring and evaluation for environmental impacts, as well as occupational safety and health standards.
