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".

These data represent the phosphate removal capacity of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana, USA, based on batch leaching experiments. Also included are major, minor, and trace element compositions of the leachates along with associated water parameters pH, specific conductivity, and alkalinity. Details of the batch 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".

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.
