What is a significant environmental risk associated with Underground Storage Tanks (USTs)?

The significant environmental risk associated with Underground Storage Tanks (USTs) is the contamination of groundwater and soil. USTs are often filled with hazardous substances, such as gasoline or other petroleum products. Over time, these tanks can corrode or develop leaks, causing their contents to seep into the surrounding soil and potentially reach the groundwater supply. This contamination poses serious risks not only to the environment but also to human health, as groundwater is a primary source of drinking water for many communities.

Contaminated soil can harm local ecosystems and disrupt fragile habitats, while contaminated groundwater can spread the pollutants over large areas, making remediation efforts complex and costly. Protecting against the risk of groundwater and soil contamination is a primary focus in the management and regulation of USTs to ensure both environmental safety and public health.
