Additional details on analytical details, confidence assignment, control experiments, quantitative results and corrections for potential losses, hopane biomarkers, toxicology and water treatment implications, and references. Tables showing a full list of mass spectral library matching derived tentative identifications and putative compound origins, potential losses to the air phase, and the quantitative outcome of volatile organic compound analysis. Figures showing a retention index verification confidence assignment plot, boiling point versus 1D retention model confidence assignment plots, effect of retention index verification filter, and hopane biomarker patterns and representative ratios
