Attenuation Capacity of Western North Dakota Overburden Sediments. Final Report
The objective of this project was to determine the cation and anion attenuation capacity of typical North Dakota overburden materials from three surface mine sites. The two overburden types that were chosen were a sandy silt and a clay. These sediments were evaluated in both oxidized and reduced states. Attenuation experiments were performed in which these sediments were treated with solutions of selected cations and anions at known concentrations. Attenuating solutions contained arsenic, selenium, molybdenum, cadmium, iron, calcium, sodium, and sulfate. These experiments were repeated at various concentration levels at four varying degrees of alkalinity and at two ionic strengths. 22 refs., 9 figs., 6 tabs. (ERA citation 11:035459)
