Chemistry Data from the Birney Test Site, Montana, 2018-2020

January 10, 2022

Data were collected to monitor geochemistry before and after an injection designed to stimulate microbial methanogenesis in the shallow Flowers-Goodale coal bed, near Birney in southeastern Montana. Waters from wells completed in the Flowers-Goodale, Nance, Knobloch, and Terret coalbeds at the Birney Test Site were sampled. Geochemical characterization of the water included non-purgeable dissolved organic carbon, acetate, major anions and cations, extractable hydrocarbons, and trace metals.
