  "description": "This metadata record contains 14 tables of biogeochemical data collected to evaluate the fate and transport of chlorinated ethenes in Area B groundwater, Fort Detrick, Frederick, Maryland collected during 2018-2020. Included in the dataset are (1) FtD_All_Constituents_NA_2019: concentrations of all non-VOC constituents analyzed as part of the natural attenuation sampling event in 2019, (2) FtD_All_Constituents_NA_2020: concentrations of all non-VOC constituents analyzed as part of the natural attenuation sampling event in 2020, (3) FtD_All_Constituents_PW_2019: concentrations of all non-VOC constituents analyzed as part of the porewater-surface water sampling event in 2019, (4) FtD_All_Constituents_PW_2020: concentrations of all non-VOC constituents analyzed as part of the porewater-surface water sampling event in 2020, (5) FtD_Concentrations_in_Rock_Matrix_VOC_2020: calculated concentrations of VOCs detected in rock matrix cores, extracted in 2020, (6) FtD_ISM_QuantArray_2020: abundance of microbial communities analyzed as part of the in situ microcosm event in 2020, (7) FtD_ISM_VOC_2020: concentrations of VOCs from the in situ microcosm event in 2020, (8) FtD_ISM_Redox_2020: concentrations of oxidation-reduction (redox) constituents from the in situ microcosm event in 2020, (9) FtD_MeOH_Extract_VOC_2020: concentrations of VOCs in methanol extracts of rock cores, extracted in 2020, (10) FtD_NA_VOC_2019: concentrations of VOCs analyzed as part of the natural attenuation sampling event in 2019, (11) FtD_NA_VOC_2020: concentrations of VOCs analyzed as part of the natural attenuation sampling event in 2020, (12) FtD_PW_VOC_2019: concentrations of VOCs analyzed as part of the porewater-surface water sampling event in 2019, (13) FtD_PW_VOC_2020: concentrations of VOCs analyzed as part of the porewater-surface water sampling event in 2020, and (14) FtD_USGS_Laboratory_evaluation_samples_VOC_2020: concentrations of VOCs analyzed as part of laboratory comparison in 2020.",
