When the location of your tank equipment’s leak is a mystery, it’s best to call a company with a tried-and-true system.

The owner of Quick Gas Mart in El Sobrante, California, contacted CGRS in October to perform a Tracer Test on a fiberglass split double-wall underground storage tank (UST) after the local CUPA inspector notified the owner that the tank failed the triannual SB989 secondary-containment testing. The original testing contractor found fuel in the tank annular, though he was unable to find the leak. The report led the CUPA inspector to believe that the primary tank had leaked into the secondary containment system and to issue a red tag. This meant that Quick Gas Mart had to shut down the dispensers pumping from that tank until the leak was identified, repaired and the system passed compliance testing.

The CGRS team performed a Tracer Tight® test that was inconclusive in verifying that the primary tank was leaking. Our team then performed two additional Tracer Tight® tests to verify that the primary containment was intact. The CGRS team then submitted an estimate to perform a helium leak locate with its iota® VaporTite V005 method. Once approved, CGRS proceeded with the test, which involves filling the tank’s components with helium and using iota® to detect from where helium was escaping.
