Sulfide data were calculated based on Na2S.11H2O as calibrated by Lan Tong with Winkler back titration on 11 July 2011 Total zero valent sulfur seem high and surprisingly constant especially above interface. However data have been included here as we have less experience with this parameter. Contact Scranton for further discussion.
