Re-analysis of the samples was not possible as the <br />samples have been discarded. <br />CT&E ID: 72-451506, Sample ID: FBR 11A, Sampled 7/7/01 <br />HC03, {2200 mg/L) > TDS, {2000 mg/L) The TDS OC data all reflected acceptable data for the run. A <br />potential source of error is the loss of C02 from conversion of HC03 to carbonates and / or partial <br />carbonate decomposition to oxides or basic salts. <br />CT&E ID: 72-457083, Sample ID: 1005, Sampled 8/6/01 <br />Na, (1060 mg / L) > TDS, (390 mg/L) Data review of the TDS and Metals analysis runs did not indicate <br />and errors with the analysis. However, after review of historical data for the sample site, the sodium <br />data seems to be in error, potentially from a sample switch during preparation. <br />If you have any questions concerning this information please contact me at (303) 373 - 4772. <br />Byron Caton <br />Operations Manager <br />ATTN RECEIVER: The information and materials Vansmitted with this fax are considered privileged and intended only for the individual or entity <br />addressed.
