Abstract
The EPA Method 1312 Synthetic Precipitation Leaching Procedure (SPLP) leachate chemistry data for mine waste samples is presented. Four mine waste composite samples were collected from Silverton (YUK and MAY) and Leadville (SUN and VEN), Colorado and were extracted following the EPA Method 1312 procedure. Leachate pH values ranged from 2.68 to 3.37 and the samples were ranked by increasing pH: VEN < SUN < YUK < MAY. Specific conductivity values ranged from 203 µS to 1080 µS and the samples were ranked by increasing specific conductivity: MAY < YUK < SUN < VEN. For selected metal concentrations, no consistent pattern presented itself. MAY is the sample that typically has the lowest metal concentrations with the exception of nickel, zinc, and lead. The samples had SPLP leachate concentrations below the EPA Method 1311 Toxicity Characteristic Leaching Procedure (TCLP) regulatory levels.
