The objective of this proposal is to develop a technique                   capable of identifying, locating and quantifying leakages                       through liners or barriers that contain hazardous leachates.                    The technique is based on the use of seismic boundary waves.                    These waves propagate along soil/water and soil/soil boundary                   created by a liner or barrier.  These boundary waves are                        focused on the liner interface and are highly sensitive to the                  conditions of this interface.  Changes in moisture, void ratio                  and permeability can be detected and correlated to leakage                      events.                                                                              On Phase I the feasibility of this concept was                             demonstrated by conducting a small scale field test.  The                       objective of Phase II is to:  confirm the concept, integrate                    the hardware, develop the analysis and interpretive software,                   develop implementation methods and interpretive techniques.
