GMA/IGS-NA Webinar – Leak Detection Sensitivity

GMA / IGS North America Webinar

Leak Detection Sensitivity – What does it mean?

(IGS Electrical Leak Location Seminar Series Episode 3*)
Presented By Abigail Gilson-Beck, M.S., P.E.

Ms. Gilson has over eighteen years of diverse civil engineering experience and is a registered Civil Engineer in
multiple states. She spent the first part of her career as a containment facility design engineer and joined TRI in 2012 to focus solely on the implementation and innovation of electrical leak location technologies. She has over fifteen years and 170 million square feet of electrical leak location experience. Her contribution to the field of electrical leak location includes numerous published technical papers, educational seminars, presentations world-wide, and chairing the ASTM committee for the recent revisions and additions to the ASTM Standard Guide and Practices.

Free to Students and Industry Professionals
The ASTM standardized methodologies detail leak detection sensitivity testing for the various electrical leak location methods. The term “sensitivity testing” is misleading, since it typically implies the ability to reliably detect a leak of a particular size. This is not the reality! The ability to detect any leak is generally a function of site conditions and the hole’s electrical contact with underlying and overlying material. Equipment can be optimized for the site conditions using and actual or artificial leak, but in many cases particular leaks can remain undetected for various reasons. This webinar details the factors affecting leak detection sensitivity for the various ELL methods. Case studies are presented that illustrate these factors. 
You will learn about:

1.How sensitivity testing and leak detection distance testing is performed
2.How equipment is calibrated for site conditions
3.How site materials factor into leak detection sensitivity
4.How conditions local to each hole affect leak detection sensitivity

5.How electrical isolation of cover material affects covered geomembrane surveys
