What is 'interstitial monitoring' used for?

Interstitial monitoring is a critical method used in the context of underground storage tanks (USTs). It primarily involves the monitoring of the space or interstitial area between the inner and outer walls of a double-walled tank system. This monitoring is crucial for detecting any leaks that may occur within the inner tank. By continuously monitoring this space, technicians can identify the presence of leaked substances, such as fuel or hazardous materials, before they can escape into the surrounding environment.

This approach helps in preventing contamination of soil and groundwater, ensuring both environmental safety and regulatory compliance. The ability to quickly detect leaks allows for timely intervention, which can mitigate potential damage and protect public health. Thus, interstitial monitoring is an essential practice in the management of USTs, focusing on safeguarding the environment and adhering to safety regulations.
