Abstract
Method, systems, and techniques for determining the age of an underground space are provided. In some embodiments, determining the age of an underground space comprises taking soil samples from a plurality of surface locations within a second underground space, analyzing the soil samples from the plurality of surface locations to determine an amount of a chemical compound for each soil sample, and determining an age of the second underground space using one or more relationships based on amounts of the chemical compound measured in a plurality of soil samples taken over a period of time in a first underground space and a baseline amount of the chemical compound at one or more locations remote from both the first underground space and the second underground space.
