Nonvolatile dissolved organic carbon (NVDOC), total petroleum hydrocarbons at the USGS crude oil study site near Bemidji, Minnesota, USA (2018)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-18T00:00:00Z
This data set describes dissolved concentrations in groundwater of nonvolatile dissolved organic carbon (NVDOC), total petroleum hydrocarbons (TPH) in the gasoline (C6-C10), diesel range (C10-C28) with and without silica gel cleanup, and oil range (>C28-C40) with and without silica gel cleanup. Groundwater samples were collected in June 2018 from the USGS crude oil study site located near Bemidji, MN. A background (reference) well located 200 m upgradient from the source and five wells along a flowline in the plume at 39, 68, 102, 125, and 254 m downgradient from the source.
