초록

The present invention integrates an inverse modeling technique and a field measurement system. The system uses inexpensive and non-hazardous gaseous tracers injected inside the contained volume of a barrier to quantify the location and size of any leaks in the barrier. The vapor sampling point installation, which allows the collection of soil gas samples from multiple points around the barrier installation, can be accomplished with conventional drilling or direct push techniques. The system uses a field-proven soil gas analyzer, incorporated in a samplin...
