Which of the following methods can be employed for leak detection in USTs?

The selected answer highlights the importance of utilizing automatic tank gauging, manual tank gauging, or inventory control systems for leak detection in underground storage tanks (USTs). Each of these methods provides a means to monitor changes in liquid levels, as well as detect discrepancies that may indicate a leak.

Automatic tank gauging systems continuously measure the volume of product in the tank using sensors and can provide alerts in real-time if there are unexpected changes in levels. This enables prompt action to address potential leaks. Manual tank gauging involves regular, scheduled measurements taken by personnel to compare liquid levels over time, which can help identify irregularities. Inventory control systems track the inflow and outflow of fuel, looking for inconsistencies that may suggest a leak.

Together, these methods form a robust approach to leak detection, ensuring compliance with environmental regulations and promoting safety. The choice of these methods reflects the requirement for effective monitoring and response protocols necessary to manage USTs responsibly.

In contrast, the other options are not viable methods for leak detection in USTs. While GPS tracking and satellite imaging aid in location services and general surveillance respectively, they do not directly monitor liquid levels or identify leaks. Daily visual inspections alone, while necessary for basic upkeep and maintenance, do not
