Composition of soil gas at the site of remediated home heating oil discharges in Virginia, United States. Samples are collected at a depth of ~2 meters at or near the exact location of a remediated underground storage tank. Gases are sampled onto an adsorbent tube and analyzed by gas chromatography coupled to mass spectrometry. Composition is characterized by total mass concentration (ug/m3) of each hydrocarbon group defined by the number of carbon atoms (N_C) and number of degrees of unsaturation (N_DBE), with saturated and mono-unsaturated (N_DBE = 1) classes further broken down into branched and unbranched compounds. Each sample is listed by a unique number, and a sequential site number indicating at which site the sample was collected; all identifying information has been removed to ensure compliance with university-approved privacy protocols. Methodological details are described in Isaacman-VanWertz et al., doi: 10.1021/acs.analchem.0c02308 . R2 changes: Added concentrations of benzene and toluene. Added Hazard Quotient of TPH and cancer risk of benzene, ethylbenzene (treating all mass with N_C = 8, ND_BE = 4 as ethylbenzene) and naphthalene.
