What is the primary purpose of a UST system?

The primary purpose of a UST (Underground Storage Tank) system is to store petroleum products and hazardous substances safely underground. This design minimizes the potential for leaks and environmental contamination, which can occur when these materials are stored above ground. By keeping these substances underground, the tanks reduce the risk of exposure to the elements, help prevent spills from reaching the surface, and comply with regulations aimed at protecting groundwater and the surrounding environment.

Options like filtering hazardous substances, treating contaminated water, or incinerating waste materials do not align with the fundamental function of UST systems, which is focused on storage rather than treatment or disposal processes. The emphasis is placed on safety, containment, and adherence to environmental standards, which are critical in managing hazardous materials effectively.
