Enclosure (1) TO COMDTINST 16478.12
Puget Sound
The percent methyl mercury for the Puget Sound samples ranges from 0.34
(Sample OFR 2) to 1.10 (Sample COL 10); concentrations range from 0.000696
mg/kg to 0/0001862 mg/kg. Figure 3-8 illustrates the percent of total mercury
as methyl mercury for Puget Sound samples. The data were variable and do not
indicate a pattern with respect to battery proximity. The methyl mercury
concentrations measured in Sample 3 (0.001962 mg/kg) collected well away from
a group of batteries was between the range of methyl mercury values measured
in sediment Samples 2 (0.000696 mg/kg) and 10 (0.003857 mg/kg), collected near
a group of batteries.
