CGRS is licensed through Praxair® to provide Tracer® testing, a leak detection method, for the retail and commercial petroleum industry. The Tracer Tight® method entails adding a small amount of highly volatile, non-contaminating tracer to the system. After a waiting period, soil vapor samples are collected adjacent to the tank and line systems. The soil vapor samples are then analyzed for the specific tracer and the target contaminant (generally hydrocarbon based) by gas chromatography (FID and ECD).

We Offer: Non-volumetric precision tightness testing for above ground and underground storage tanks Enhanced Leak Detection Monthly monitoring for fuel systems

The Tracer Tight® method enables us to test without interruption of service. It also gives us the ability to locate and characterize leak sources without excavation. Tracer Tight® may also be used to fulfill the requirements of monthly monitoring and is an approved method in the state of Colorado for testing AST tank bottoms. In addition, the target chemical data obtained during the test can help in risk management, as an effective tool to target possible problem sites for remediation.
