What common environmental risk is associated with UST systems?

Groundwater contamination from leaked substances is a significant environmental risk associated with Underground Storage Tank (UST) systems. USTs are designed to store hazardous materials, including fuels and chemicals. If these tanks develop leaks or if their integrity is compromised, the substances can seep into the surrounding soil and subsequently infiltrate the groundwater. This can lead to widespread contamination, posing serious risks to drinking water supplies and impacting ecosystems.

Groundwater is a critical resource for both human consumption and agricultural use, making its protection paramount. The risks associated with groundwater contamination are not just localized; they can affect large areas, complicating cleanup efforts and leading to long-term environmental and public health challenges.

While the other environmental risks mentioned have their own importance, they do not represent the most common or critical concern related to UST systems compared to groundwater contamination, which has overarching implications for health, safety, and environmental integrity.
