TM94-09 Calculation error on mercury bottom material data

Due to a calculation error by laboratory personnel, all mercury bottom material results (Test ID 71921A) for samples analyzed from August through December 1993 have been updated. This problem affected about 100 samples. The results were originally reported as <0.1 μg/g. These values have been changed to reflect either the correct detection limit value of <0.01 μg/g or a reported value between 0.01 μg/g and 0.1 μg/g.
