Which of the following is a consequence of failing to maintain UST systems properly?

When UST systems are not properly maintained, one of the primary consequences is environmental contamination. A malfunctioning UST can result in leaks or spills of hazardous substances into the surrounding soil or groundwater, posing significant risks to public health and the environment. Such contamination can lead to legal issues, as regulatory agencies may impose fines, require costly clean-up efforts, or even take legal action against the responsible parties.

In addition to the immediate environmental concerns, the implications can extend to the affected communities, including potential drinking water contamination and harm to local ecosystems. Proper maintenance practices are essential to prevent these negative outcomes and ensure compliance with environmental regulations. Thus, the failure to maintain UST systems properly primarily leads to environmental contamination and associated legal and financial ramifications.
