Abigail Gilson, M.S., P.E., is the Director of TRI Environmental’s Liner Integrity Services. She has a wealth of experience in geomembrane-lined containment facility design and construction and has performed liner integrity surveys since 2004. As a graduate of TRI’s inaugural liner integrity survey class in 2003, her liner integrity and leak location field experience has exceeded 180 million square feet and well over 100 projects. 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.
