Which factor is critical when selecting geomembrane materials for landfill operations?

• A. The color of the geomembrane
• B. The material's resistance to environmental factors
• C. The ease of installation
• D. The thickness of the geomembrane

Answer: (B)

Selecting geomembrane materials for landfill operations primarily centers around the material's resistance to environmental factors. This is because geomembranes serve vital functions such as preventing leachate migration, controlling gas emissions, and protecting against soil contamination. The right material needs to withstand various conditions, including chemical exposure, temperature fluctuations, UV radiation, and mechanical stresses. A geomembrane's ability to resist degradation from these environmental factors ensures its longevity and effectiveness in containment. If the material is not sufficiently resistant, it may lead to potential failures, resulting in environmental hazards and increased operational costs. While color, ease of installation, and thickness are relevant factors in the overall consideration of geomembrane selection, they do not carry the same level of critical importance as environmental resistance in terms of the material’s performance and reliability in landfill operations.
