Abstract
A method for conducting environmental sampling includes determining to environmentally sample a particular paper transit ticket for a specific residue. Using an automated ticket device, at least one chemical reagent is applied to the particular paper transit ticket. The chemical reagent is selected based on the specific residue. The particular paper transit ticket is collected after the particular paper transit ticket was used as a fare media within a transit system. The at least one chemical reagent is analyzed to determine whether any of the specific residue is present.
