* = digested in duplicate. † = analyzed using ICP-OES; Zn reference material results are for ICP-OES. ‡ = analyzed at a larger dilution factor than others; therefore, no oxide correction was applied. For Sample 331-C0014B-3H-5, 20–30 cm, we disregarded a high Zn and Cd value from one duplicate digestion. These samples were not rerun to ascertain accurate concentrations, but in each case they would have had the highest concentrations measured during this study (Zn ~ 3800 µg/g and Cd ~ 10 µg/g). For Sample 331-C0017D-7H-5, 80–90 cm, one Re value was below the detection limit (BDL) and one was just above; we report the value above the detection limit.
