Re: Dioxin Testing Report of Findings For The Von Drehle Corporation
Cordova Plant And Land Application Sites (Hamlet and Highway US-1)
Richmond County, NC
Permit Number WQ005135
Mr. Barber,
Enclosed please find a copy of the Dioxin Testing Report Of Findings for the above
referenced sites. Dioxin compounds have essentially been found in very low
concentrations (picograms per liter) at every site, off, and on the properties. Dioxins were
identified in all non -disturbed and native soil background samples. Dioxin has also been
identified in the on -site potable water supply. Evidence of dioxin compounds at
comparable concentrations has also been found in the laboratory QA/QC sample results.
Only three of the samples collected as part of this investigation were found at any level
above any applicable State action limit. As shown on Figure 4, at least five potential
sources of dioxins were identified within a 2 mile radius of the Cordiva Plant. Four of these
are located adjacent to Hitchcock Creek, and up flow gradient from the Plant. The
prevailing wind direction within the area of investigation is to the northeast, with some
southwestern and southeastern flow components. This was considered due to the dioxin
concentrations found in the stream discharge sample obtained adjacent to the air
discharge stacks.
It is concluded that dioxin compounds, although very low, are prevalent throughout the
environment in the Rockingham and Hamlet areas. The presence of dioxins in the
laboratory results also leads to the simple fact that dioxins are also present in our
environment at very low concentrations.

The following recommendations are made:
1. As part of the tri-annual monitoring events, initiate groundwater and stream
sampling at the Cordova Plant to monitor the low level dioxin compounds
present and to track and help identify significant changes that may adversely
affect human health or the environment.
2. Include soil and groundwater monitoring at the land application sites as part
of the tri-annual monitoring events.
3. Further evaluate the potential for the off -site source areas to be additional
dioxin contributors.
Should you have any questions and/or concerns please do not hesitate to contact this

PREPARED FOR:
VON DREHLE CORPORATION
HICKORY, NORTH CAROLINA
February 19, 2015
1.0 SITE HISTORY
The Von Drehle Corporation Plant is located in Cordova, Richmond County, NC.
The Plant is comprised: of approximately 29.88 acres of land adjacent to First Street
and Zion Church Road. The project location is depicted -in aerial view on Figure 1.
Site historywas determined through aerial photograph review,. personal interviews,
historical environmental reports, and other historical reviews. It appears that the
subject property was utilized as a textile mill from the late 1800s to the 1980s. The
site currently operates as a paper recycling facility. The Plant utilizes two land
application fields for fiber clay disposal. Petroleum soil and groundwater impacts
were identified at the Cordova Plant associated with former USTs, ASTs, and a
ruptured pipeline incident. Abatement activities were conducted within the release
areas. The incidents have been issued No Further Actions by the State.
A Phase I -Environmental Site Assessment was completed by Card no ATC. Cardno
ATC's investigation identified the following two areas of concern:
1. Chemical storage and process areas showing evidence of releases by
staining and cracks within the concrete floor surfaces.
2. Former on -site wastewater treatment plant in the southwest portion of the
site across First Street.

1
February 19, 2015
Six test wells were identified by the contractor during their Phase I activities.
Reportedly, no known soil or groundwater impacts above regulatory levels were
known to exist at the time of the assessment.
As part of their Phase II assessment activities, Cardno ATC sampled the six pre-
existing test wells, plus installed six temporary monitoring wells to address data
gaps in the other test wells. All of the test well groundwater samples were analyzed
for VOCs. Dioxins were .analyzed from eight of the groundwater samples. In
addition, soil samples were submitted from the boreholes:of each temporary well
and analyzed for VOCs- and SVOCs. All of the soil samples were found to be
compliantforall hydrocarbon compoundstested. The groundwater sample findings
revealed all VOC and SVOC compounds to be compliant. A dioxin compound
identified as OCDD-(octochlorodibenzo-p-dioxin) was found to exist within five of
the seven shallow test wells. Concentrations ranged from 0:26 to-0.98 ng/L. The
soil samples were- not analyzed for dioxins during the assessment.
Applied Resource Management, P.C. (ARM) was contracted by the Von Drehle
Corporation to confirm the presence of the dioxin OCDD at the Plant. Initial findings
revealed the dioxin to be present at every testing location. Soil, groundwater, and
surface water stream samples were all found to be impacted by OCDD at very low
levels. It should be noted.:that the laboratory method blank samples for both soil
f` and water were also found to contain trace levels- of OCDD as reported in the
discussion section of the lab report dated August 22, 2014. Expanded dioxin
assessment activities were conducted at the Plant as well as the two land
application fields, .and are'addressed within the following sections.
Research has indicated that OCDD has been associated with bleaching of paper
pulp. Reportedly, the Plant facility does not conduct bleaching operations. It is
unclear if the raw material being recycled has undergone bleaching as part of its
original manufacturing process.
2.0 PURPOSE
The purpose of this report is to provide findings and recommendations for the dioxin
testing. activities conducted by Applied Resource Management, P.C. at the Cordova
Plant, and land application sites (Hamlet and US-1). Initial findings at the Cordova
Plant revealed OCDD to be present in soil, groundwater, and stream samples;
therefore, an expanded dioxin investigation was conducted at the land application
sites.

3.0 ASSESSMENT ACTIVITIES
ARM has conducted extensive soil, groundwater, stream, and steam discharge
sampling activities at the Cordova Plant and land application sites in August and
November, 2014. The assessment activities consisted of the following:
• Advancement of numerous soil borings, soil descriptions and sampling, and
background soil sampling.
• Groundwater monitoring well sampling, water supply and waste water
sampling, and collection of pond/stream samples.
• Steam discharge sampling conducted at the Cordova Plant.
Sampling activities are provided for each site location as follows:
3.1 Cordova Plant
(Refer to Figures 1, 1A, Tables 1A, 2A, and Appendices A and B)
As part of the initial dioxin testing activities, the following were conducted:
• Cardno ATC found two of their temporary monitoring wells to be
impacted with OCDD. Two replacement monitoring wells, MW-9R and
MW-11 R were constructed in place of previously abandoned
temporary wells.
• All wells previously found to be impacted by dioxins (MW-2, MW-3,
MW-5, MW-6, MW-9 and MW-11) were sampled for EPA Method
1613B for OCDD only..
• Soil borings were advanced immediately adjacent to. the OCDD
impacted well locations and soil samples collected for lab analysis.
• Two stream samples, identified as Stream Up and Stream Down were
collected immediately adjacent to the Plant in the north portion of the
property.
Low level OCDD concentrations were found at every sample location as
shown on Tables 1A and 2A. Trace levels of OCDD were also found in the
laboratory method blanks in soil and water. Due to these findings, it was
recommended by ARM to expand the investigation at the Plant, and include
the two application fields. As a result, the following were conducted:
L 3

February 19, 2015
• One on -site waste water sample, W-1, was collected from a
wastewater pipeline outside and adjacent to the northern portion of
the Plant.
• One water supply sample, PW-1, was obtained from the public water
supply to the Plant.
• One background soil sample, BG-3, was collected approximately 500
feet southeast of the Plant in undisturbed native soils.
• Two stream samples were collected from approximately 0.5 miles
upgradient and downgradient of the Plant as shown on Figure 1A.
• One steam discharge sample, AS-1, was obtained -on the Plant roof
top adjacent to the air discharge stacks as partof a 24.hour Method
T09 sampling event. The steam sample was collected utilizing a
portable high volume T09 Puff Air Sampler. Flow rates were
calculated at 241 liters per minute and a total air volume of 347,622
liters of air after a 24 hour test period.
All of the samples were submitted for laboratory analysis.per USEPA Method
1613B full list dioxins.
3.2 Hamlet Land Application Site
(Refer to Figures 2 and 2A)
As part of the expanded dioxin investigation activities, the following were
conducted:
• Eleven soil borings, D-1 thru D-11 were advanced within designated
fiber clay application areas to two feet deep. Each boring was logged
by field description to segregate the fiber clay material plow zone
from the native soil. All soils samples were collected from
undisturbed native soil.
One background soil sample, BG-1, was obtained approximately
4,000 feet southwest of the application fields in undisturbed native
soils (see Figure 2A).
In addition, the five on -site monitoring wells (MW-1 thru MW-5) and
two ponds located in the central portion of the site were sampled.

February 19, 2015
3.3 US-1 Land Application Site
(Refer to Figure 3)
The following activities were conducted at this site:
Twelve soil borings, D-12 thru D-23 were advanced within
designated: fiber clay application areas to two feet deep. Each
boring was logged by description to segregate the fiber clay material
plow zone from the native soil. Soil samples were collected and
analyzed -for full list dioxins.
One background soil sample, BG-2, was obtained in the far west
portion of the property across US-1 Highway in undisturbed native
soils and analyzed for full list dioxins.
Monitoring well MW-11 was found to be damaged and could not be
sampled. With the exception of MW-11, all of the on -site monitoring
wells were gauged purged, and sampled for full list dioxins.
4.0 Soil Sampling Activities With Results
(Refer to Figures 1,1A,2,2A,3, Tables 1A,1B,1C, and Appendices A and B)
4.1 Cordova Plant
Soil borings were advanced immediately adjacent to the impacted OCDD
well locations to seven feet below ground surface. Soil samples were
collected from each borehole with a decontaminated hand auger bucket or
split spoon. The soil samples, identified as MW-2/S-1, MW-3/S-1, MW-5/S-
1, MW-6/S-1, MW-9R/S-1, and MW-11 R/S-1, were analyzed for OCDD
only. Boring logs are provided in Appendix A. As shown on Table 1A, low
level concentrations of OCDD were found at all six soil sampling locations
ranging from 0.38 ppm to 6.5 ppm. No preliminary health based soil
remediation goals have been established by the IHSB for this compound.
One background soil sample, BG-3, was collected approximately 500 feet
southeast of the Plant in undisturbed native soils. Dioxin compounds
including 2,3,7,8-TCDD, 1,2,3,4,7,8-HxCDD, 1,2,3,6,7,8-HxCDD, and
1,2,3,7,8,9-HxCDD(hexachlorodibenzo-p-dioxin)were found to be present
within the background soil sample, BG-3 was found with laboratory
estimated concentrations above the IHSB Residential and Industrial Health
Based Remediation Goals. It should be noted that several of the dioxin
compounds were also found at estimated low levels within the laboratory
method blank sample.

February 19, 2015
4.2 Hamlet Land Application Site
Eleven soil borings, D-1 thru D-11 were advanced within designated fiber
clay application areas to two feet below ground surface. Each boring was
logged by field description to segregate the fiber clay material from the
native soil. Fiber clay content was typically found from surface to
approximately 10" below ground surface. Soil samples were collected from
the native soil each borehole with a decontaminated hand auger bucket at
the 18" to 24" interval. Also, one background. soil sample, BG1, was
obtained approximately 4,000 feet southwest of the application fields in
undisturbed native soils. All of the soil samples were analyzed per EPA
Method 161-313 for full list dioxins. As shown on Table 1 B, OCDD was found
in all of the soil samples at low level concentrations. Other dioxin
compounds were found in most of the samples at estimated low level
concentrations. D-6 revealed a laboratory estimated non -compliant
1,2,3,7,8,9-HxCDD concentration of 0.00055 .ppm, exceeding -the IHSB
Residential and Industrial Health Based. Remediation Goals currently at
0.000094 and 0.00039 ppm.

5.0 Water Sampling Activities With Results
(Refer to Figures 1,1A, 2, 2A, 3, Table 2A, 213, 2C and Appendices A and B)
5.1 Cordova Plant
Comprehensive water sampling activities included:
• Groundwater sampling of the on -site monitoring wells.
• Potable water supply sampling to the Cordova Plant.
• Waste water sampling.
• Stream sampling in upstream and downstream locations.
Water sampling activities are described in the following sections:
5.1.1 Groundwater Sampling
As part of the initial dioxin groundwater testing activities, two
replacement monitoring wells, MW-9R and MW-11 R were
constructed in place of previously abandoned temporary wells which
were identified by ATC to be impacted- with OCDD (See Figure 1).
Boring logs, As -Built Well Details, and NC Well Construction
Records are provided in Appendix A. All wells previously found to
be impacted (MW-2, MW-3, MW-5, MW-6, MW-9R and MW-11 R)
were gauged, purged of at least three well volumes, and
groundwater samples collected for analysis per EPA Method 1613B
for OCDD only. As shown on Table 2A, low level OCDD
concentrations ranging from 0:00016 to 0.011 ppb were found at all
six monitoring well locations. No ' specific action limit has been
established by NCDENR under NCAC 02L Groundwater Standards
or IHSB Protection of Groundwater for this compound.
5.1.2 Stream Sampling
Two stream samples were initially collected from the north portion of
the Von Drehle Cordova. Plant property. As shown on Figure 1, the
water samples were obtained immediately upgradient and
downgradient of the Plant. The samples were identified as Stream
Up and Stream Down, and were analyzed for OCDD only. Findings
revealed both samples to contain low level laboratory estimated
7

�j
February 19, 2015
concentrations of OCDD at 0.000041 and 0.000058 ppb. As such,
additional stream samples were collected from approximately 0.5
miles upstream and downstream from the Plant. Low level
concentrations of OCDD were also found at both of these locations.
In addition, low level estimated concentrations of HpCDD ranging
from 0.000012 ppb to 0.000027 ppb were found in the upstream
sample. No other dioxin compounds were identified.
5.1.3 Potable. Water Supply Sampling
One potable water supply sample, PW-1, was collected from the
municipal water supply, from the mens' bathroom lavatory inside the
Cordova Plant office. The sample was analyzed for full list dioxins.
As shown on Table 2A, all of the dioxin compounds are non detected
with the exception of a low level laboratory estimated concentration
of OCDD at 0.0000074 ppb. It should be noted that OCDF, a
daughter product of OCDD, was identified in the laboratory method
blank sample at a similar estimated concentration of 0.000011 ppb.
5.1.4 Waste Water Sampling
One wastewater sample, WW-1, was collected from discharge atthe
north portion of the Cordova Plant. The sample was analyzed for full
list dioxins. As shown on Table.2A, all of the dioxin compounds are
non detected with the exception of a. low level estimated
concentration of OCDD at 0.0000088 ppb. It should be noted that
OCDF, a daughter product of OCDD, was identified in the laboratory
method blank sample at a similar :estimated concentration of
0.000011 ppb.
5.2 Hamlet Land Application Site
Comprehensive water sampling activities included:
Groundwater sampling of the on -site monitoring wells.
Pond water samples collected from the two drainage ponds located
in the central portion of the property.
Water sampling activities are described in the following sections:
T

February 19, 2015
5.2.1 Groundwater Sampling
Groundwater samples were collected fromthefive on -site monitoring
wells, MW-1 thru MW-5 (See Figure 2). Priorto sampling, each well
was gauged and purged of at least three well volumes. Groundwater
samples were submitted for analysis per EPA Method 1613B for full
list dioxins. As shown in Table 2B, low level estimated OCDD
concentrations were found at monitoring wells MW-3, MW-4 and
MW-5. The laboratory estimated concentrations ranged from
0.000013 to 0.000089 ppb. It should be noted that OCDD was also
found to be present in the laboratory method blank sample at a
similar estimated concentration of 0.000009 ppb.
5.2.2 Pond Water Sampling
Pond water samples identified as Pond-1 and Pond-2 were collected
from the two drainage ponds located in the central portion of the
property (See Figure 2). Both water .samples were submitted for
analysis per EPA Method 1613B for full. list dioxins. As shown in
Table 2B, no dioxin compounds were found to be present at either
pond location.
5:3 US-1 Land Application Site
5.3.1 Groundwater Sampling
Groundwater samples were collected from six of the seven on -site
monitoring wells, MW-6 thru MW-12 (See Figure 3). MW-11 was
found to be damaged and was not sampled. Prior to sampling, each
well was gauged and purged of at least three well volumes.
Groundwater samples were submitted for analysis per EPA Method
1613B for full list dioxins. According to Table 2C, low level
estimated OCDD concentrations were found at, monitoring wells MW-
6, MW-9 and MW-12. The concentrations ranged from 0.000013 to
0.000027 ppb. It should be noted that OCDD was also found to be
present in the laboratory method blank sample at a similar estimated
concentration of 0.000009 ppb.

6.0 Steam Discharge Sampling Activities With Results
(Refer to Figure 1, Table 3, and Appendices B and C)
As part of this investigation, ambient air sampling activities were conducted at the
Cordova Plant. A portable high volume TO9 Puff Air Sampler Unit was set up on
the Plant roof top and immediately adjacent to the air discharge stacks. The
approximate sampling location area is depicted on Figure 1. After machine
calibration was completed, the quartz fiber filter and glass Puff cartridge were
installed in the unit. The air sampler was run for a continuos 24 hour period with
an average magnehelic flow of 42. Flow rates were calculated at 241 liters per
minute and a total air volume of 347,622 liters of air. A TE-1000 PUF Calibration
Worksheet is provided in Appendix C. After the testing period was completed, the
filter and cartridge were prepared, labeled AS-1, wrapped in aluminum foil and
place on ice for laboratory pickup. The steam discharge air sample was analyzed
per Method TO9 for full list dioxins. As shown on Table 3, several dioxin
compounds were identified at very low levels. None of. the concentrations were
found to . exceed the NCDENR Toxic Air Pollutant Guidelines for Annual
Carcinogens. It should be noted that very low level dioxins 2,3,4,7,8-PeCDF and
OCDD were also detected in the laboratory method blank sample at similar
concentrations.
7.0 OFF -SITE POTENTIAL DIOXIN SOURCES
(Refer to Figure 4)
Figure 4 presents several points and information. First, note the wind direction
diagram on the bottom of the map. The prevailing wind direction is to the
northeast, with some southwestern and southeastern flow components. This was
considered due to the dioxin concentrations found in the steam discharge sample
results. Second, 0.5, 1, and 2 mile radii were imposed on the map for quick
referenced. Third, a quick industrial history of the area was completed. Note that
at least five (5) additional potential sources of dioxins were identified in the area.
Four of these are located adjacent to Hitchcock Creek, and up flow gradient from
the site.
8.0 CONCLUSIONS AND RECOMMENDATIONS
Findings of this investigation have revealed the following:
Very low OCDD concentrations to be present in all of the soil samples
collected from all three sites, including the laboratory method blanks for
both the Cordova Plant and the US-1 Land Application Site.
10

February 19, 2015
Dioxin concentrations were found in all three background soil samples
collected from each of the three areas of investigation.
One non -compliant soil sample was found at each of the three sampling
sites. Cordova Plant background soil sample, BG-3, contained several
dioxin compounds above the IHSB remediation goals. D-6 from the Hamlet
application site and. D-16 from the US-1 site revealed HxCDD
concentrations above the IHSB remediation goals.
Low level OCDD_concentrations were found to be present in all of the
groundwater, stream, water supply and wastewater samples collected for
the Cordova Plant. In addition, OCDD was found to be present at estimated
low levels in several of the monitoring wells at both land application sites,
as well as in the laboratory method blank samples for.Hamlet and US-1 at
similar concentrations.
• The dioxin HcCDD was found at very low estimated concentrations in
monitoring well MW-12 at the US-1 site. No groundwater standards have
been established for this dioxin.
• Dioxin concentrations were found higher in the 0.5 mile upstream sample
than in the 0.5 mile downstream sample. This suggests at least one other
dioxin source off of the subject property.
Several dioxins were found in the steam discharge sample collected at the
Cordova Plant. Findings revealed that: none of the contaminant
concentrations were above the established limits as per 15A NCAC 02D
.01104.
Dioxin concentrations have essentially been found at every site, off, and on the
properties. Dioxins were identified in all non -disturbed and native soil background
samples. Dioxin has also been identified in the on -site potable water supply.
Evidence of dioxins at comparable concentrations has also been found in the
laboratory: QA/QC sample results. Only three of :the samples were found at any
level above any State action limit. It is concluded that dioxin compounds, although
very low, are prevalent throughout the environment in the Rockingham and Hamlet
areas. Presence of the dioxins in the laboratory results also leads to the simple
fact that dioxins are prevalent in our environment at very low concentrations.
It is logical that dioxins would be found associated with site operations, but these
concentrations are at such low levels, it is believed that an imminent threat from
site operations to human health or the environment likely does not exist. We are
11

February 19, 2015
simply measuring the background presence of dioxins at very low concentrations
throughout the surrounding environment.
The following recommendations are made:
1. As part of the tri-annual monitoring events, initiate groundwater and stream
sampling at the Cordova Plant to monitor the low level dioxin compounds
present and to track and help identify significant changes that may
adversely affect human health or the environment.
2. Include soil and groundwater monitoring at the land application sites as part
of the trkannual monitoring events.
3. Further evaluate the potential for the off -site source areas to be further
contributors of dioxins.

DISCUSSION

1700 Elm Street
Minneapolis, MN 55414
Phone: [phone]
Fax: [phone]
This report presents the results from the analyses performed on fourteen samples
submitted by a representative of Pace Analytical Services, Inc. The samples were
analyzed for the presence or absence of octachlorodibenzo-p-dioxin (OCDD) using
USEPA Method 1613B. The reporting limits were based on signal-to-noise
measurements.
The recoveries of the isotopically -labeled OCDD internal standard in the sample
extracts ranged from 57-76%. All of the labeled standard recoveries obtained for this
project were within the target ranges specified in Method 161313. Also, since the
quantification of the native OCDD was based on isotope dilution, the data were
automatically corrected for recovery and accurate values were obtained.
In one case, an interfering substance impacted the determination of OCDD; the
affected value was flagged "I" due to an incorrect isotope ratio. Concentrations below
the calibration range were flagged "J" and should be regarded as estimates. 0r ez
reported concentration was above the calibration range, flagged "E", and should also
be regarded as an estimate.
A laboratory method blank was prepared and analyzed with each sample batch as part
of our routine quality control procedures. The results show Blank-41661 to contain a
trace level of OCDD. This level was below the calibration range of the method. The
OCDD concentrations reported for the associated field samples were higher than the
corresponding blank level by three or more orders of magnitude. These results indicate
that the sample processing steps did not contribute significantly to the levels reported
for the field samples.
Laboratory and matrix spike samples were also prepared using clean sand, water, or
sample matrix that had been fortified with native standard material. The results show
that the spiked native OCDD in the laboratory spike samples was recovered at
111-122% with relative percent differences (RPDs) of 5.0-5.3%. The
background -subtracted recoveries obtained for the matrix spike analyses were above
the 70-130% target range, possibly due to sample inhomogeneity. The RPD value
obtained for the matrix spike analyses was 14.1 %. Matrix spikes were not prepared
with the water sample batch.

DISCUSSION

Fax: [phone]
This report presents the results from the analysis performed on one sample submitted
by a representative of Pace Analytical Services, Inc. The sample was analyzed for the
presence or absence of polychlorodibenzo-p-dioxins (PCDDs) and
polychlorodibenzofurans (PCDFs) using a modified version of USEPA Method T09A.
The reporting limits were based on signal-to-noise measurements. Estimated
Maximum Possible Concentration (EMPC) values were treated as positives in the toxic
equivalence calculations. The sample was extracted outside of the 7-day hold time
recommended in the method, therefore, the reported concentrations should be
regarded as minimum possible concentrations.
The recoveries of the isotopically labeled PCDD/PCDF internal standards in the sample
extract ranged from 69-101 %. All of the labeled internal standard recoveries obtained
for this project were within the target ranges for the method. Also, since the internal
standards were added to the samples prior to the extraction step, the data were
automatically corrected for recovery and accurate values were obtained.
The recoveries obtained for the PCDD/PCDF surrogate compounds in the field sample
ranged from 68-92%. All of the surrogate recoveries obtained for this project were
within the 50-120% target range specified in the method. These results indicate that no
significant breakthrough occurred during sample collection.
In some cases, interfering substances impacted the determination of PCDD or PCDF
congeners; the affected values were flagged "I" where incorrect isotope ratios were
obtained. Concentrations below the calibration range were flagged "J" and should be
regarded as estimates.
A laboratory method blank was prepared and analyzed with the sample batch as part of
our routine quality control procedures. The results show that PCDDs and PCDFs were
not detected.
Laboratory quality control PCDD/PCDF spike samples were also prepared with the
sample batch using clean PUF cartridges that had been fortified with native standards.
The results show that the spiked native compounds were recovered at 91-124% with
relative percent differences of 0.0-12.4%. These results indicate high degrees of
accuracy and precision for these determinations. Matrix spikes were not prepared with
the sample batch.

This report presents the results from the analyses performed on five samples submitted
by a representative of Pace Analytical Services, Inc. The samples were analyzed for
the presence or absence of polychlorodibenzo-p-dioxins (PCDDs) and
polychlorodibenzofurans (PCDFs) using USEPA Method 161313. The reporting limits
were based on signal-to-noise measurements. Estimated Maximum Possible
Concentration (EMPC) values were treated as positives in the toxic equivalence
calculations. This report was revised to present results for all tetra through
octachlorinated PCDDs and PCDFs.
The recoveries of the isotopically -labeled PCDD/PCDF internal standards in the sample
extracts ranged from 53-97%. All of the labeled standard recoveries obtained for this
project were within the target ranges specified in Method 1613B. Also, since the
quantification of the native 2,3,7,8-substituted congeners was based on isotope
dilution, the data were automatically corrected for variation in recovery and accurate
values were obtained.
In some cases, interfering substances impacted the determinations of PCDD or PCDF
congeners; the affected values were flagged "I" where incorrect isotope ratios were
obtained. Concentrations below the calibration range were flagged "J" and should be
regarded as estimates. One reported concentration was above the calibration range,
flagged "E", and should also be regarded as an estimate.
A laboratory method blank was prepared and analyzed with each sample batch as part
of our routine quality control procedures. The results show the blanks to contain trace
levels of selected congeners. These levels were below the calibration range of the
method. The levels reported for the affected congeners in the associated field samples
were higher than the corresponding blank levels by one or more orders of magnitude.
These results indicate that the sample processing steps did not contribute significantly
to the levels reported for the field samples.
Laboratory spike samples were also prepared with the sample batches using clean
sand or water that had been fortified with native standard materials. The results show
that the spiked native compounds were recovered at 101-130% with relative percent
differences of 0.0-10.8%. The recoveries obtained for 1,2,3,4,6,7,8-HpCDF in three of
the four laboratory spike samples were above the target range, flagged "R" on the
results tables, and may indicate a high bias for this congener in these determinations.
However, since HpCDF isomers were not detected in the field sample analyses, the
accuracy of the reported results was not impacted by these deviations. Matrix spikes
were prepared with the solid sample batch using sample material from a separate

project; results from these analyses will be provided upon request. Matrix spikes were
not prepared with the water sample batch.
The labeled cleanup standard in the solid field sample extract was inadvertently added
at 1.5 times the amount specified in our procedures. The actual spike amount was
used in the calculations and an accurate recovery value was reported. It should be
noted that the accuracy of the native congener determinations was not impacted by this
deviation.

This report presents the results from the analyses performed on nineteen samples
submitted by a representative of Pace Analytical Services, Inc. The samples were
analyzed for the presence or absence of polychlorodibenzo-p-dioxins (PCDDs) and
polychlorodibenzofurans (PCDFs) using USEPA Method 161313. The reporting limits
were based on signal-to-noise measurements. Estimated Maximum Possible
Concentration (EMPC) values were treated as positives in the toxic equivalence
calculations.
The recoveries of the isotopically -labeled PCDD/PCDF internal standards in the sample
extracts ranged from 28-119%. Except for two low values, which were flagged "R" on
the results tables, the labeled standard recoveries obtained for this project were within
the target ranges specified in Method 1613B. Also, since the quantification of the
native 2,3,7,8-substituted congeners was based on isotope dilution, the data were
automatically corrected for variation in recovery and accurate values were obtained.
In some cases, interfering substances impacted the determinations of PCDD or PCDF
congeners; the affected values were flagged "I" where incorrect isotope ratios were
obtained. Concentrations below the calibration range were flagged "J" and should be
regarded as estimates.
A laboratory method blank was prepared and analyzed with each sample batch as part
of our routine quality control procedures. The results show the water blanks to contain
trace levels of selected congeners. These levels were below the calibration range of
the method. Sample levels similar to the corresponding blank levels were flagged "B"
on the results tables and may be, at least partially attributed to the background. It
should be noted that levels less than ten times the background are not generally
considered to be statistically different from the background.
Laboratory and matrix spike samples were also prepared with the sample batches
using clean sand, water, or sample matrix that had been fortified with native standard
materials. The results show that the spiked native compounds were generally
recovered at 88-130% with relative percent differences (RPDs) generally from
0.0-15.1%. The recoveries obtained for 1,2,3,4,6,7,8-HpCDF in LCS-42979 and for
1,2,3,7,8,9-HxCDD in LCSD-43106 were above the target ranges, flagged "R" on the
results tables, and may indicate high biases for these congeners in the associated field
sample determinations. Also, the background -subtracted recoveries obtained for
2,3,4,7,8-PeCDF and 1,2,3,6,7,8-HxCDD in the matrix spike and/or matrix spike
duplicate were above the 70-130% target range; these results may also indicate high
biases for the affected congeners. The RPD obtained for 1,2,3,7,8,9-HxCDD in the

laboratory spikes prepared on 12/08/2014 was above the 20% target upper limit and
may indicate elevated variability for this congener. However, since the affected
congeners were not detected in the associated field sample analyses, the accuracy of
the reported results was not impacted by these deviations. Matrix spikes were not
prepared with the water sample batches or with the 12/04/2014 solid sample batch.

DISCUSSION

Fax: [phone]
This report presents the results from the analyses performed on nineteen samples
submitted by a representative of Pace Analytical Services, Inc. The samples were
analyzed for the presence or absence of polychlorodibenzo-p-dioxins (PCDDs) and
polychlorodibenzofurans (PCDFs) using USEPA Method 161313. The reporting limits
were based on signal-to-noise measurements. Estimated Maximum Possible
Concentration (EMPC) values were treated as positives in the toxic equivalence
calculations.
The recoveries of the isotopically -labeled PCDD/PCDF internal standards in the sample
extracts ranged from 20-126%. Except for fourteen low values, which were flagged "R"
on the results tables, the labeled standard recoveries obtained for this project were
within the target ranges specified in Method 1613B. Also, since the quantification of
the native 2,3,7,8-substituted congeners was based on isotope dilution, the data were
automatically corrected for variation in recovery and accurate values were obtained.
In some cases, interfering substances impacted the determinations of PCDD or PCDF
congeners; the affected values were flagged "I" where incorrect isotope ratios were
obtained. Concentrations below the calibration range were flagged "J" and should be
regarded as estimates. Concentrations above the calibration range were flagged "E"
and should also be regarded as estimates.
A laboratory method blank was prepared and analyzed with each sample batch as part
of our routine quality control procedures. The results show the water blank to contain
trace levels of selected congeners. These levels were below the calibration range of
the method. Sample levels similar to the corresponding blank levels were flagged "B"
on the results tables and may be, at least partially attributed to the background. It
should be noted that levels less than ten times the background are not generally
considered to be statistically different from the background.
Laboratory spike samples were also prepared with the sample batches using clean
sand or water that had been fortified with native standard materials. The results show
that the spiked native compounds were generally recovered at 88-128% with relative
percent differences (RPDs) generally from 0.0-15.1 %. The recovery obtained for
1,2,3,7,8,9-HxCDD in LCSD-43106 was above the target range, flagged "R" on the
results table, and may indicate a high bias for this congener in the associated field
sample determinations. Also, The RPD obtained for 1,2,3,7,8,9-HxCDD in the
laboratory spikes prepared on 12/08/2014 was above the 20% target upper limit and
may indicate elevated variability for this congener. However, since HxCDD isomers

Calculations
Qstd 1/m[Sgrt((H20)(Pa/760)(298%Ta))-b] m = sampler slope
Flow (corrected)=Sgrt((magn)(Pa/Pstd)(Tstd/Ta)) _ b = sampler intercept
(magn) = magnehelic reading
Qstd = standard flow rate Tav = daily average temperature
Flow (magn)= reading from magnehelic:gauge Pav = daily average pressure
Flow (corrected) corrected flow rate
m = calibrator astd slope. -
b = calibrator Qstd intercept
Ta = actual temperature during calibration (deg K)
Pa = actual pressure during calibration (mm Hg)
Tstd = 298 deg K
Pstd = 760:rnm Hg
For subsequent calculation of sampler flow:
Qstd = 1/m[Sgrt((H20)(Pa/760)(298/Ta))-b]
