... the theoretical response of both types of survey to a hole in a liner and then compare with measurements made in the field. The theoretical leak response indicates that above-liner surveys are sensitive to leaks over a greater area, though both responses result in comparable leak detectability. However, field...

... Acoustic Emission leak detection and location for liquid-filled, buried pipelines was studied using various leak sources and laboratory reference standards.These standards provided significant data that have contributed to the development of test procedures for generating two-phase flow...

... of leak detection and the role of measurement precision. The important methodological issues of identifying and discriminating among sources of apparent volume changes which are not related to leakage, and the analysis and interpretation of test results will also be addressed. volumetric leak...

.... Airport hydrant systems are currently deferred from the leak detection requirements of the federal EPA regulations covering underground storage tanks. However, several states, eg. Texas, have neither exempted nor deferred these systems. These states are regulating hydrant systems on a case by case basis...

... The need for improved leak detection and corrective action has prompted research into the movement of hydrocarbon vapors from leaking underground storage tanks (USTs) as well as the build-up of liquid hydrocarbon on the water table. This research has included the development of two evaluation...

... Vapor monitoring for leak detection around underground storage tanks (UST) is generally regarded as being plagued by false alarms. Examples of field data from six sites are provided. Vapor monitoring indicates real leak or spill events but methods are needed to differentiate between the two...

... In 1990, EPA released a series of “Standard Test Procedures for Evaluating Leak Detection Methods” to define consistent, rigorous procedures for determining the performance of underground storage tank leak detection methods. Each test procedure outlines one or more ways to evaluate...

... Leaking underground storage tank systems present an environmental concern and a potential health hazard. It is well known that leaks in the piping associated with these systems account for a sizeable fraction of the leaks. EPA has established performance standards for pipeline leak detection...
