Abstract

Covers the results of the fourth phase of a program to define and advance the state of the art leak detection for aboveground storage tanks (ASTs). Three leak detection methods are examined, passive acoustic, soil vapor monitoring and volumetric, over a wide range of tank types, petroleum fuels and operational conditions. Also evaluates the applicability of a general leak detection methodology involving multiple tests and product levels as well as determining the integrity of 14 ASTs using two or more test methods.
