This sample was replicated by creating a field duplicate sample. Two batches of analyses bottles were prepared from the same sample. The dissolved chromium and dissolved zinc concentrations from the field duplicate agree more closely with the previous two samples. Possible cause for the discrepancy might be the contamination of the sample bottle during preparation or sample processing. The analyses for the field duplicate are available upon request.
