Table 13: Low level mercury results for samples collected in Lake Whatcom, selected tributary creeks, and the Middle Fork of the Nooksack River on October 11 and 15, 2001 by Exponent. All samples were analyzed by Frontier Geosciences (detection limit = 0.00000002 mg/L for methyl hg; 0.0000002 mg/L for total hg). Note that Frontier Geosciences’ original results were reported as ng/L in Appendix B.8 (1 ng/L = 0.000001 mg/L).
