What is the function of monitoring wells in a UST system?

Monitoring wells play a crucial role in the integrity and environmental safety of underground storage tank (UST) systems. Their primary function is to monitor groundwater contamination. They are strategically placed around the UST system to sample and analyze groundwater for hazardous substances that may have leaked from the tank or its associated piping. By sampling the groundwater, operators can detect early signs of contamination, assess the extent of any potential leaks, and take the necessary steps to mitigate risks to the environment and public health. This monitoring is vital for ensuring compliance with environmental regulations and for preventing long-term groundwater pollution, which can be difficult and expensive to remediate.

While other choices incorporate relevant concepts related to UST systems, they do not accurately describe the specific purpose of monitoring wells.
