What is one potential risk associated with contaminated groundwater from UST leaks?

One significant risk associated with contaminated groundwater from UST leaks is the potential impact on public health. When underground storage tanks leak, hazardous substances such as petroleum products or chemicals can seep into the groundwater. This contamination can affect the safety and quality of drinking water supplies that many communities rely on. Exposure to polluted groundwater can lead to a range of serious health issues, including respiratory problems, skin irritation, and long-term effects such as cancer or other chronic diseases. Furthermore, communities may face increased healthcare costs and loss of trust in local water safety, highlighting the critical importance of monitoring and managing USTs to prevent such risks.

In contrast, the other options suggest outcomes that are unlikely to arise from UST leaks, such as improved tourism or increased property values, which typically decline in areas with known environmental issues. Additionally, the emergence of new plant species is generally not considered a direct benefit of groundwater contamination, as native ecosystems are often harmed rather than improved.
