What is the purpose of vapor monitoring in UST systems?

The purpose of vapor monitoring in Underground Storage Tank (UST) systems is primarily to detect the presence of vapors that may indicate a tank leak. This monitoring technique plays a critical role in environmental protection by identifying potential leaks before they can lead to significant contamination of soil and groundwater.

When vapors escape from a tank due to a malfunction or structural failure, they may rise and accumulate in the subsurface environment. By implementing vapor monitoring systems, operators can promptly identify these leaks, potentially minimizing environmental damage and ensuring compliance with regulatory standards.

Additionally, detecting vapors early can help prevent safety hazards associated with exposure to flammable substances, thus protecting both personnel and the public. Overall, vapor monitoring serves as a vital tool for maintaining the integrity of UST systems and safeguarding environmental health.
