A different lab (Accu-Labs Research Inc.) was used for the 4 and 12 week composites. Accu-
• Labs used more sensitive analytical techniques which resulted in lower detection limits. A copy
of these data are included in appendix 6.
The bulk of the data incorporated into the graphs of this appendix are from the Chemax dataset.
The Accu-Labs data which are included are those analyses for the 4 week composites of the
following five samples: CC91-14(135-138'), CC92-36(29-32'), CB-6132, CC90-4(441-451'),
and CC90-5(190-195'). These five humidity cells were started recently, and the only trace
element data available are those from Accu-Labs.
Included in this appendix are graphs of humidity cell drainage values for pH and sulfate plus the
following elements:
Aluminum
Arsenic
Cadmium
Chromium
Copper
Iron
Lanthanum
Manganese
Molybdenum
Vanadium
• Zinc
Included, where available and appropriate, are the maximum, minimum, and average water
quality values from the AG-1 site (Appendix 11). Also shown is the 0.8% ST cutoff for Cresson
waste. Note that the humidity cell samples are ranked by ST content along the x axis. The
values for each sample, taken over successive 4 week increments (as explained above), are
plotted in the graph field above the appropriate "waste rock sample number". The
corresponding drill sample number and total sulfur value for the "waste rock sample number"
is given in the table beneath each graph.
Results of the analyses for some of the trace elements not graphed are summarized below:
Antimony - no values above the detection limit.
Barium - no values above the upper detection limit; 9 values above the lower
detection limit ranging from 0.05-0.08 mg/L with the exception of one
value of 0.15 mg/L.
Beryllium - one value above the detection limit.
Bismuth - one value above the detection limit.
Gallium - no values above the detection limit.
Lead - no values above the upper detection limit; 3 values above the lower
detection limit (0.005, 0.16, and 0.29 mg/L).
Lithium - no values above the detection limit.
Mercury - no values above the upper detection limit; one value above the lower
. detection limit (0.0001 mglL).
Nickel - no values above the upper detection limit; 8 values above the lower
