EVALUAR METHODOLOGY
The EVALUAR methodology was designed to evaluate the
dual-purpose rehabilitation of a mining- impacted land
parcel. This method integrates technical, environmental,
and economic considerations into a structured approach
for land restoration and sustainable reuse. The methodol-
ogy involves four stages: Evaluate, Validate, Adjust, and
Reflect.
• Evaluate: Initial analysis of contamination levels,
identification of suitable techniques for soil move-
ment and encapsulation, and feasibility studies for
tourism and agricultural uses.
• Validate: Testing the proposed techniques, verifying
post-remediation contamination levels, and assessing
the suitability of the encapsulated soil for crops and
livestock.
• Adjust: Refining methods and strategies based on
pilot test results and adapting them to the specific
characteristics of the site.
• Reflect: Assessing the long-term effectiveness of the
interventions, measuring their impacts, and develop-
ing recommendations for future projects or policies.
So, if we follow the stages of EVALUAR cycle, we have:
EVALUATE
This initial stage involves evaluating the conditions of the
land to be rehabilitated and analyzing contamination levels
in the different zones. It also includes identifying suitable
techniques for soil movement and encapsulation, consider-
ing technical and economic feasibility.
This involves:
• Analyzing contamination levels in the upper and
lower parts of the land.
• Identifying and selecting appropriate techniques for
soil movement and encapsulation.
• Studying the capacity of the encapsulated soil to sup-
port short-stem plants and evaluating its impact on
the geomembrane.
• Conducting a preliminary analysis of the potential
uses of the upper part (hiking/tourism) and lower
part (livestock/agriculture).
VALIDATE
In this stage, proposed solutions are validated to ensure
they meet environmental quality standards and are feasible
for the planned uses of the land.
