What is a significant risk associated with UST systems if not properly maintained?

Increased fuel sales
Environmental contamination
Enhanced performance of the system
Lower operational costs

The correct answer is: Environmental contamination

A significant risk associated with underground storage tank (UST) systems, if not properly maintained, is environmental contamination. UST systems are designed to store fuel and hazardous materials safely underground. However, if there are leaks or structural failures due to neglect, the stored substances can escape into the soil and groundwater, leading to significant environmental damage. Environmental contamination can have a wide range of detrimental effects, including harming local ecosystems, contaminating drinking water supplies, and necessitating costly cleanup efforts. Proper maintenance and regular inspections are crucial for preventing such incidents and ensuring that the UST system operates safely and compliantly. The other options, such as increased fuel sales, enhanced performance of the system, or lower operational costs, do not represent risks associated with UST systems but rather hypothetical positive outcomes that do not relate to maintenance issues. These factors could be influenced by various operational decisions and strategies, rather than the direct consequences of poor maintenance.
