Technology Type:
Detection/Monitoring and Remediation

Technology Description:
Service interruptions are costly and disruptive to tank owners. When there is a leak, the Tracer Tight™ test can discover it before it becomes a serious problem that may lead to expensive remediation and liability expense. The Enhanced Tracer Tight™ is a variation of the standard Tracer Tight™ test, but with greater leak sensitivity. The standard test provides a leak sensitivity of 0.05 gallons per hour (gph), while the enhanced version provides a leak sensitivity of 0.005 gph. The Enhanced Tracer Tight™ test was developed to meet the 0.005 gph leak detection requirement set forth by the State of California Water Resource Control Board (SWRCB). This one order of magnitude improvement is achieved by strategically adding additional data points (probes), and by altering the amount of "tracer" compound introduced into the system. The objective is to identify any releases from a system (liquid and/or vapor).

Application:
The Tracer Tight™ test is effective for all types of installations, including tanks and pipes buried under pavement, concrete or buildings. It provides a rapid and cost-effective means of assessing pipeline integrity through new super-sensitive tracer chemical technology.

Environmental Benefits:
Pipeline integrity becomes more proactive and not reactive because miles of line can be scanned for small "seeper" size leaks quickly and inexpensively.

Performance:
Leaks as small as a gallon a day can be identified and located for repair. Depending on pipeline route, up to 4-5 miles of pipeline a day can be evaluated.

In addition, Tracer Tight™ has/is:

• No Fill Requirement: Enhanced Tracer Tight™ does not require specific levels of product, like some volumetric test methods. In fact, tanks can be tested completely empty.
• No Down Time: Enhanced Tracer Tight™ does not inhibit system operation. Your system will remain in use during the entire test period.
• Not affected by hydrocarbons in the soil from previous leaks or spills.
• Accepted by the State of California Water Resource Control Board as a method capable of achieving the 0.005 gph leak detection requirement.
• Third-Party approved evaluation by Ken Wilcox & Associates.

Limitations:
Pipeline route needs to be located accurately and cleared adequately to allow sampling equipment to be dragged over the surface of the ground.
