What is a common method to check for leaks in USTs?

Installing leak detection systems is a common method for checking for leaks in underground storage tanks (USTs). These systems are specifically designed to monitor the UST for potential leaks continuously or at predetermined intervals. By utilizing technologies such as sensors, automatic tank gauging, and vapor monitoring, leak detection systems provide real-time data and alerts when a leak is detected, allowing for immediate response and mitigation efforts.

This method is highly effective compared to other approaches because it actively monitors the integrity of the tank rather than relying solely on visual assessments or anecdotal evidence. While methods such as pressure testing can be part of leak detection strategies, having a dedicated system in place enhances the reliability of the monitoring process.

Visual inspections alone may not reveal all leaks, especially if they are minor or occurring underground. Similarly, conducting interviews with nearby residents does not provide direct evidence of leaks and relies on subjective reports. Therefore, the implementation of an active leak detection system represents the best practice for ensuring the safety and environmental compliance of USTs.
