IGS-NA hosts free electrical leak location webinar  

News | November 17, 2017 | By:

IGS North America (IGS-NA) presents the free webinar “Overview of Electrical Leak Location (ELL) Methods and Their Application” on Nov. 21, 2017, at 1:00 p.m. EST.

All geomembrane-lined containment facilities should be tested for leaks before going into service. Early detection of leaks allows for swift and effective repair pre-service, protecting the engineer, contractor, owner and, in many cases, the environment. There are a variety of different methods available. Choosing and specifying the most appropriate method requires an understanding of the various technologies, as well as their benefits and limitations. In many applications an ELL method must be specified in the design phase, before construction starts, to ensure a successful test.

This presentation identifies the common ELL technologies and details criteria that should be considered when specifying ELL methodology. Participants can earn 1 PDH at the conclusion of this webinar.

The webinar will be taught by Abigail Gilson, M.S., P.E., director of TRI Environmental’s Liner Integrity Services. Gilson has a wealth of experience in geomembrane-lined containment facility design and construction, and has performed ELL surveys since 2004. As a graduate of TRI’s inaugural liner integrity class in 2003, her ELL field experience has exceeded 100 projects and 110 million square feet. She has written and presented papers to industry conferences and taught short courses worldwide regarding the technical aspects of liner integrity and leak location surveys.
