Observed Average Sulfate Concentration and Mass in Rivers and Seeps

  • * 545 gpm at conc of 811 mg/L (Flow from Table 6.2 "Simulated Versus Estimated Seep Flow Rates and Groundwater Discharge Rates" - CRA June 2013 Report:)

  • Calculations are based on observations from approximately 2000 to present except for the Dark River Stream which are from 3 measurements from November 2011 to September 2012

  • SCS = Seepage Collection System
