Table F-1. Minimum and maximum 2015 values for each metal and the creek sediment in which it occurred. Control creeks are indicated with an asterisk (*).
Minimums shown with < represent the DL for metals not detected (Method, Instrument, or Estimated Detection Limit per analytical method). Silver (Ag) detected
only in Long Creek (0.068 pg/g) and Muddy Creek (0.077 pg/g).

Table F-2. Values of sediment metals in 2015 in the PCS creeks study. Creeks are listed with most
upstream creek on South Creek first (Jacks Creek) and proceed downstream by creek to Hickory Point and
Muddy Creek, then upriver along the Pamlico to the most western creeks (DCUT11 and DCUT19). Control
creeks are indicated with an asterisk (*). Entries with < were undetected and value shown is LOQ/CL
(reporting limit and control limit.)
