1. A leak detection system for detecting leaks from a storage system containing a liquid less dense than water in which water has collected at the bottom of the storage system to form a water level and a separate liquid level, comprising:

  • a tracer, the tracer comprising a substance soluble in the liquid to provide a liquid-tracer mixture upon introduction into the liquid, the tracer operable to provide a detectable component in the liquid-tracer mixture;

    a second detectable tracer, soluble in water, operable to mix with water and escape with the water through a leak in the storage system within the water level;

    a tracer introduction mechanism for introducing the tracers into the liquid; and

    a sampling device positioned near the storage system, the sampling device containing adsorption material for adsorbing tracer from the liquid-tracer mixture and the water-tracer mixture.
