These data represent the air-free pH and specific conductance per pore volume of effluent generated by the phosphate removal column experiment. Solid samples used for the columns are of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana, USA.

These data represent the major, minor, and trace element compositions of effluent water samples generated by column experiments of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana. Details of the column experiments may be reviewed in the journal article listed in the cross-reference section of this data release titled, "Geochemical Characterization of Iron and Steel Slag and Its Potential to Remove Phosphate and Neutralize Acid".
The Ironwood Iron-Formation, part of the Gogebic Iron Range in Wisconsin, is a Paleoproterozoic Superior-type banded iron formation (BIF) with substantial iron resource potential. The development of a Mesoproterozoic contact metamorphic aureole related to the emplacement of the Mellen Intrusive Complex resulted in the production of a variety of silicate minerals in the western portion of the Ironwood Iron-Formation, including amphibole, pyroxene, and olivine. The presence of amphibole minerals, some of which occur in a fibrous habit, has complicated development of this resource due to potential human health impacts. This data release provides information related to amphibole and other minerals in order that commercial,...

These data represent the acid neutralization potential and grain size analysis of 13 samples, 2 duplicate samples, of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana, USA.
Stable hydrogen (H), oxygen (O), and sulfur (S) isotope data were collected from the Elizabeth copper mine Superfund site, South Strafford, Vermont. Sample media include surface water (H and O), groundwater (H and O), dissolved sulfate (O and S), and sulfide minerals in bulk mill tailings samples. Where available, supporting data for water samples include discharge, pH, specific conductance, and dissolved sulfate concentration. The water samples span a time period from August 1998 to October 2009.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
