Geological disposal is a method used to safely store hazardous waste, particularly radioactive materials, deep underground. This process involves placing waste in stable geological formations, such as salt or clay, which can effectively contain the materials for thousands of years. The goal is to prevent any harmful substances from reaching the surface or contaminating the environment. Before a geological disposal site is chosen, extensive studies are conducted to assess the area's geology, hydrology, and potential risks. Regulatory bodies, such as the Nuclear Regulatory Commission, oversee these projects to ensure safety and compliance with environmental standards.
