From objectives and scope: The objectives of the study were to: (1) Determine the geographic extent of the minable lignite beds and identify aquifers down to a depth of about 400 feet beneath the lower minable lignite; (2) assess the ground-water flow regime in all aquifers found; (3) evaluate the flow characteristics of the two streams draining the study area; and (5) qualitatively assess the impacts mining might have on the hydrologic system.

This baseline risk assessment of ground water contamination at the inactive uraniferous lignite ashing site near Bowman, North Dakota, evaluates the potential impacts to public health or the environment from contaminated ground water at this site. This contamination is a result of the uraniferous lignite ashing process, when coal containing uranium was burned to produce uranium. Potential risk is quantified only for constituents introduced by the processing activities and not for the constituents naturally occurring in background ground water in the site vicinity. Background ground water, separate from any site-related contamination, imposes a percentage of the overall risk from ground water ingestion in the Bowman site vicinity. The US Department of Energy (DOE) Uranium Mill Tailings Remedial Action (UMTRA) Project is developing plans to address soil and ground water contamination at the site. The UMTRA Surface Project involves the determination of the extent of soil contamination and design of an engineered disposal cell for long-term storage of contaminated materials. The UMTRA Ground Water Project evaluates ground water contamination. Based on results from future site monitoring activities as defined in the site observational work plan and results from this risk assessment, the DOE will propose an approach for managing contaminated ground …

This report presents field and laboratory data for 585 groundwater samples and 201 stream sediment samples collected from the Grand Forks quadrangle in North Dakota and Minnesota.

From abstract: "Laboratory studies of uraniferous coal were started in connection with explorational core drilling in 1951. The cores were described and used for coal analyses, for determinations of uranium and other mineral elements, and for microscopical investigations. Results of microscopical studies are feature in this report."

During the months of August and September, 1979, geoMetrics, Inc. collected 12,415 line miles of high sensitivity airborne radiometric and magnetic data in adjoining portions of South Dakota and Minnesota over seven 1 by 2 degree NTMS quadrangles (Thief River Falls, Grand Forks, Fargo, Milbank, Watertown, New Ulm, and St. Cloud). All radiometric and magnetic data were fully corrected and interpreted and are presented as eight volumes.
