Which of the following is a known risk associated with underground oil tanks?

Groundwater contamination from leaks that can occur over time is a well-documented risk associated with underground oil tanks. Over time, aging tanks or those that have not been properly maintained can develop leaks. When oil leaks from these tanks, it can seep into the surrounding soil and ultimately reach groundwater supplies. This not only poses a risk to the environment but can also have serious health implications for communities that rely on that groundwater for drinking and other uses.

The significance of this issue is underscored by environmental regulations that require proper monitoring and maintenance of underground tanks, as well as protocols for immediate action in the event of a leak. Addressing and preventing groundwater contamination is crucial for protecting public health and preserving natural resources.
