Respuesta :
Adding buffering compounds to neutralize acids is used to address acid mine drainage.
Therefore, the correct option is C.
Adding lime or other alkaline materials to neutralize the acidity of the soil, as well as adding uncontaminated topsoil, planting vegetation, and modifying slopes to stabilize the soil and reduce surface water infiltration into the underlying contaminated material, are some of the common methods for cleaning up contaminated land. The most commonly used technique for treating AMD contamination is the use of alkaline reagents like lime, limestone, sodium carbonate, or sodium hydroxide. The purpose of this process is to neutralize acidic water and prevent the precipitation of heavy metals.
Acid mine drainage (AMD) is a global problem that has negative effects on the ecosystem. Because of its high acidity and high concentration of heavy metals and metalloids, AMD is harmful to both plants and animals as well as to people. Traditional AMD therapies have been in use for a very long time.
