What is the primary purpose of underground storage tank (UST) systems?

The primary purpose of underground storage tank (UST) systems is to store petroleum or hazardous substances safely. USTs are specifically designed to contain liquids, which can include fuels such as gasoline, diesel, and heating oil, as well as other hazardous materials that require safe storage to prevent leaks and environmental contamination. This capability is critical due to the potential risks associated with improper storage of these substances, including groundwater pollution and soil contamination.

While other options mention storage or management, they lack the comprehensive focus on the nature of substances that USTs are designed for, which is specifically aimed at petroleum products and hazardous materials categorized under regulatory frameworks. UST systems are equipped with monitoring and leak detection systems to ensure that any potential issues are identified quickly, maintaining safety standards and environmental protection.
