2014 Sediment and Water Column Metals
(Data only on CD)
Table F -1. Minimum and maximum 2014 values for each metal and the creek sediment in which it occurred. Control creeks are indicated with an asterisk ( *).
Minimums shown with < represent the LOQ /CL (reporting limit/control limit).

Table F -2. Values of sediment metals in 2014 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.)
