I. Introduction and Project Background
Polychlorinated biphenyls (PCBs) are a complex mixture of similar manmade chemicals
with from 1 to 10 chlorines attached to a biphenyl structure (Figure 1). They are
produced by direct chlorination of biphenyl with chlorine gas. By adjusting the reaction
conditions, manufacturers were able to produce different mixtures with different average
degrees of chlorination (1). Monsanto, the manufacturer of PCBs in the United States
produced these chemicals at two facilities trademarked under the name Aroclor.
Mixtures of other chlorinated polyaromatic compounds such as terphenyls were also
produced (2,3). Each Aroclor was given a number as part of its name which indicated
the weight percent of chlorine in the mixture (i.e. Aroclor 1254 is approximately 54% by
weight chlorine). There are 209 possible structural combinations of chlorinated
biphenyl; the 209 different combinations are referred to as “congeners”. Each congener
has a structure-based name and a shorthand name developed by Ballschmitter (1),
which is a number from 1 to 209 (See Appendix A) based on the IUPAC naming
conventions.
Analytical chemistry methods exist that allows the composition of PCB complex
mixtures to be deciphered, i.e. the concentration of each congener in the PCB mixture
can be measured. This approach is termed “PCB congener-specific analysis”.

Conducting investigations of PCB environmental contamination on a congener-specific
basis allows the relative concentrations of PCBs (often referred to as “patterns” or
“fingerprints”) to be evaluated. Different Aroclors and mixtures of Aroclors have
different fingerprints; this is an important consideration in designing environmental
forensic investigations because the fingerprints of PCBs can be used to better
understand the source, fate and effects of PCB contamination. Contamination can also
be expressed as a total concentration of PCBs by summing the congener
concentrations and arriving at what is referred to as “total-PCB” concentration.
Polychlorinated biphenyls were manufactured from the mid 1930s to the early 1970s at
a facility in Anniston Alabama. During that period company records indicate that PCBs
were released into ditches outside of the facility that lead to Snow Creek (2,3).
Investigations conducted since the 1980s have found that fish, sediments and soils in
the Anniston area and downstream are contaminated with PCBs (2). The
environmental fate of PCBs released from the Anniston facility is under investigation to
evaluate the extent of potential injury to natural resources. The US Geological Survey,
in collaboration with the US Fish and Wildlife Service and Geological Survey of
Alabama, undertook this reconnaissance investigation to provide a preliminary
assessment of the distribution, concentrations, and fingerprint (patterns) of PCBs (on a
congener specific basis) in sediments collected from aquatic environments upstream
and downstream of the former PCB manufacturing facility. This information will be used
to design a comprehensive assessment of the extent and severity of injuries to natural
resources of the region.

II. Site Selection and Sample Collection
Thirteen sites (Figure 2, Appendix B) were selected for this reconnaissance
investigation of PCB sediment contamination, including sites downstream of the Solutia
facility beginning with Eleventh Street ditch, followed by downstream sites in Snow
Creek and Choccolocco Creek. Areas outside of the surface water drainage path from
the Solutia facility, including sites on Coldwater Creek and Choccolocco Creek were
also selected for sampling.
Personnel from the U.S. Fish and Wildlife Service (FWS), the U.S. Geological Survey
(USGS), and the Geological Survey of Alabama (GSA) collected sediments on the
dates 15-17 September 2003 for this investigation. Depending on availability at each
site, depositional areas near the surface of the water, midstream bed sediments and

cores from the bank were sampled. USGS Standard Operating Procedures (SOPs)
were used to collect the sediment samples (4). In order to obtain a spatially integrative
sample of the surficial sediments (the top 2-3 cm) at a site, 5 to 7 sub-samples were
spoon sampled at each site and combined (4). The GSA identified bank depositional
areas from which segments of sediments 5-10 cm deep were collected using a coring
device fitted with clean, disposable sleeves. Bed sediments were sampled from mid-
stream and in the reservoirs using a Petite ponar. After each zone was sampled, the
sediments were homogenized on site in the stainless steel bowl by stirring thoroughly
for several minutes, and then transferred into a pre-cleaned, glass jar fitted with an
aluminum foil lid liner. Sediments collected were < 2 mm particle size and did not
require sieving. All sampling equipment was cleaned prior to sampling and cleaned
after each use by washing with soap and water, followed by rinses of distilled water,
acetone, hexane, and then allowed to dry.
Sediments were kept at 4°C in coolers and handled under chain of custody. The FWS
Daphne Field Office shipped samples overnight to USGS Columbia Environmental
Research Center (CERC) on September 18, 2003.
III. Summary of Analytical Methods
1. Sample Preparation
Sediment samples were analyzed for PCBs using congener-specific methods described
by USGS-CERC SOPs (Figure 3), with total PCBs quantified by a summation of
congeners. Two sediments were analyzed in triplicate to determine method
reproducibility. The following quality control (QC) samples were incorporated into the
various analyses:
1-Procedural blank: to measure laboratory background and to establish method
detection limits.
2-Sediment matrix blank: to measure laboratory background.
8
3-Sediment matrix spike (PCB spiked): to demonstrate recovery through the
analytical method
4-Positive Control Sediment: CERC laboratory reference material, Saginaw
River sediment.
Portions of sediment were used for sediment particle sizing, and determination of
percent organic carbon and percent moisture. Particle size analysis was performed by
the Bouyoucos method (5). The organic carbon was determined by difference: total
carbon by combustion and inorganic carbon by evolved carbon dioxide (6). Percent
moisture was determined using an oven to dry the sediment (7).
The PCB analytical procedure began by homogenizing sediment samples by stirring
with a clean, solvent-rinsed, stainless steel spoon and weighing out 10-gram portions.
The sediment portions were dehydrated by addition of anhydrous sodium sulfate, and
surrogate recovery compounds were added and allowed to equilibrate overnight. A
mixture of Aroclors 1242, 1248, 1254, and 1260 (in a 1:1:1:1 ratio) was added to control
blank sediment to create the sediment matrix spikes. The following surrogate recovery
compounds were added to all samples including samples used for QC:
PCB 029 (2,4,5-trichlorobiphenyl)
PCB 155 (2,2',4,4',6,6'-hexachlorobiphenyl)
PCB 204 (2,2',3,4,4',5,6,6'-octachlorobiphenyl)
These PCBs are used as surrogates because they are rarely found or undetectable in
Aroclors and they are chromatographically resolvable. The three surrogates are used to
correct for analytical recoveries of the PCBs: PCB 029, a trichlorobiphenyl, is
representative of more volatile early eluting PCBs (Cl1 - Cl3); PCB 155, a
hexachlorobiphenyl, is representative of mid-range eluting congeners (Cl4 - Cl6); and
PCB 204, an octachlorobiphenyl, is less volatile and representative of later eluting PCBs
(Cl7 - Cl10). Evaluation of the sediment matrix spikes and positive controls also gives
recovery information for PCB congeners.

The sediments were Soxhlet extracted overnight with dichloromethane (8,9). Co-
extracted biogenic compounds were removed from the extracts by a two stage reactive
cleanup followed by high performance size exclusion chromatography (HPSEC) (10).
The resulting fractions were prepared for gas chromatography with electron capture
detection (GC/ECD). The sample extracts were adjusted to a final volume of 2 mL.
Two instrumental internal standards were added: PCB congeners 030 and 207 (40
ng/mL each).

2. Summary of Gas Chromatographic Method for PCB congeners
Individual PCB congeners were measured by dual-column GC/ECD using Hewlett-
Packard 5890 Series II GCs with cool on-column capillary injection systems and
Hewlett-Packard model 7673 autosamplers (11). For all analyses, a 3-m section of 0.53
mm i.d. uncoated and deactivated capillary retention gap (Agilent, Palo Alto, CA) was
attached to each analytical column by a Press-Tight® (Restek Corp., Bellefonte, PA)
union. The dual analytical columns were 60-m x 0.25-mm x 0.25μm DB-5 (5% phenyl-,
components analysis of potential sources of polychlorinated dibenzo-p-dioxin and
dibenzofuran residues in surficial sediments from Newark Bay, New Jersey” Arch.
