How do you test a landfill liner is sealed properly?

The above diagram shows the method that is now used for testing the integrity of the liner used in land fill sites, the pressure is increased within the hollow section and monitored, it has to remain constant for a set amount of time. How long? What pressures are involved? This liner is used with a 1 meter thickness of clay as an additional liner. In hazardous waste sites this clay can be as thick as 5 meters.
