Figure 3-26. Observed benzo[a]pyrene concentration for Bedford-1 soil at both the 4°C and -20°C
holding temperature by holding time and associated Day 0 nonparametric bounds;
there was no significant negative trend.
For the Eagle Harbor soil's fluorene, and phenathrene data, storage at -20°C limited the loss of
these PAHs as well as the other five (Figs. 3-10, 3-11 and Table 3-22). While the loss of
chrysene and benzo[a]pyrene, regardless of storage temperature, was limited, most of the data
are still within the 95% confidence interval (Fig. 3-13, 3-14). For the most part, the six
representative PAHs exhibited stability for a length of time at least double that of the
recommended MHT in all 3 soils/sediments and both storage conditions.
All of the Eagle Harbor and SQ-1 PAHs and all but six of the Bedford-1 PAHs had observations
that fell outside of the Day 0 nonparametric boundaries (Figs. 3-21 to 3-26). For the Bedford-1
55
-------
soil, the higher molecular weight PAHs (benzo[k]fluoranthene and heavier) had only extreme
outliers for observations on day 168. No observations that could be used for the analysis after
day 14 (Fig. 3-24). Thus, only these PAHs were plotted and a holding time was not calculated.
3.2.1.3 PAH Holding Time Study - Conclusions: The objective of this study was to
determine if significant loses of PAHs occurred when sediment/soil samples were stored at either
4°C or -20°C for a period of 168 days (12*MHT). Samples from three field sites were examined.
Of the 20 compounds that were quantified, there were only significant differences in the mean
concentration between samples stored at the two temperatures for about half of the PAHS in the
Eagle Harbor soil (Tables 3-10 and 3-21). The estimated number of days for eight PAH
compounds to decrease by 20% in Eagle Harbor soil ranged from 92 to 272 days for storage at
4°C and 138 days for one PAH stored at -20°C (Table 3-22). These data indicate that the stability
of PAHs varies with both sediment/soil type and storage conditions. The instability of the lower
molecular weight PAHs in the Eagle Harbor soil stored at 4°C is consistent with results of other
studies and probably is the result of both volatilization and biodegradation. Storage of the Eagle
Harbor soil at -20°C prior to extraction was observed to ameliorate the problem of low molecular
weight PAH concentration loss.
3.2.2 Polychlorinated Biphenyls (PCBs)
Concentrations of PCB congeners and Aroclors were characterized through time in three
sediments/soils; Housatonic River sediment, SQ-1 sediment, and Tri-Cities soil, and for two
holding temperatures (4°C and -20°C) (Appendix A, Descriptive Statistics Tables A-8 to A-10).
None of the analytes were analyzed in all three of the sediments/soils (Table 3-23). Housatonic
River sediments were analyzed for Aroclors 1254 and 1260. The SQ-1 sediment was analyzed
for Aroclor 1254, and Tri-Cities soil was analyzed for Aroclors 1242 and 1260 and seven PCB
congeners. All of the observed concentrations for the specific congeners and aroclors tested were
above 2*MDL. The SQ-1 sediment (after correction) had the lowest concentration of Aroclor
1254 averaging 125 ng/g (dry weight). The Housatonic River sediment had the highest
concentration of Aroclor 1260 averaging 23,400 ng/g. The Tri-Cities soil had the highest
concentration of Aroclor 1242 averaging 26,800 ng/g.
The value of CV<25% was considered the allowable variability between replicates for SVOC
extraction. Table 3-23 shows the mean concentration and CV of all Day 0 data accepted for
statistical analysis (including potential statistical outliers), and the across time CV for the data at
4°C and -20°C (i.e., all data across a time sequence except for Day 0). For the Aroclor analyses,
only the SQ-1 sediment exhibited Day 0 CVs>25%, but once the data was surrogate corrected
(discussed below), the CV was reduced to 0.6%. No other Day 0 CVs exceeded 25% although
congener PCB-8 extracted from the Tri-Cities soil came close with a CV=24.7%.

a Cells highlighted with light yellow have CVs greater than 25%, and blank cells indicate analytes for which a sediment was not
characterized.
The results shown in Table 3-23 for the mean and CV of across time data (excluding Day 0 data)
for sediment held at 4°C and -20°C, can be viewed as an estimate of data variability. The
variability arising for the across time CV analysis is a combination of sample heterogeneity,
analytical precision, and the variability with time. Given the metric of CV<25%, much of the
data for a given time sequence (excluding Day 0), soil or sediment, and storage temperature
could be considered valid replicates regardless of holding time.
For the SQ-1 Aroclor 1254 analyses, 1 observation from the -20°C sediments and two from the
4°C sediments were identified as extreme outliers (observations greater than the 75th percentile
plus 3 times the interquartile distance of the Day 0 data). These observations (3 out of 20 = 15%)
were identified in the plot (Fig. 3-29; discussed below) but they were not removed from the
analysis since the number of extreme outliers was greater than 10%. For the Tri-Cities soil,
analysis of individual PCB congeners, eight observations from the -20°C sediments and seven
from the 4°C sediments (15 out of 257 = 6%) were considered extreme outliers and were
removed from the analysis but not the plots (Fig. 3-34 to 3-40; discussed below).
3.2.2.1 Surrogate Correction of SQ-1 Sediment PCB Extraction Data: The SQ-1 sediment
was this project's first PCB extraction study. Over the life of the timed study with this sediment,
it was observed that surrogate recovery (concentration and % recovery) increased with holding
time (days to extraction; Figure 3-27). Thus, the SQ-1 results for Aroclor 1254 were surrogate
corrected using the surrogate PCB-198 per procedure (see section 2.2.4). However, even though
extracts were not held greater than 40 days (the MHT based on the analytical method), it was
noticed that extracts older than 30 days and surrogate corrected had a reduced Aroclor 1254
concentration (Figure 3-28). The age of the extract appeared to be a confounding factor.

Figure 3-28. SQ-1 surrogate corrected data as a function of the age of

Extracts older than 30 days were from the early sampling periods (Day 0-Day 7). While the
reason for the apparent time dependence was not determined, for the statistical analysis, only
extracts held for less than 30 days were used and the starting time of the experiment (Day 0) was
moved to the original Day 14. Interestingly, the same extract of SQ-1 for PCB analysis was
utilized in the PAH study (section 3.3.1) and no evidence of this type of behavior was noted in
those analyses. Regardless of organic contaminant of interest, all remaining extracts (except for
Bedford-1 pesticide) where analyzed prior to 30 days.

3.2.2.2 Statistical Analysis of PCS Extraction Data: Once analyte extraction data for all
soils, storage temperatures, and holding time sequence were surrogate corrected (SQ-1 sediment)
and statistical outliers removed, data for a given soil and storage temperature were pooled across
time (0 to 168 days). The mean, standard deviation and CV were calculated for the pooled data
(Table 3-24). Strictly based on the metric CV<25% as a measure of acceptable replicate
precision, the overall CV showed that all measurements for a given soil and analyte could be
considered valid replicates despite holding times prior to extraction stretching over 168 days.
The exceptions to this observation were congeners PCB 8 (at 4°C and -20°C), PCB 153 (at 4°C
and -20°C), and PCB 180 (at 4°C), which exhibited CVs slightly greater than 25. These data
confirm the general perception that PCBs in soils and sediments tend to have a long half-life.
These findings do not preclude the possibility that PCB concentrations change over the time
studied; rather, by the aforementioned metric data falls within the acceptance criterion for
replicate precision.
A one-sample t-test of the null hypothesis Ho: the sample is from a population with the mean
equal to or greater than the Day 0 mean, was rejected for both Aroclors found in the Housatonic
River sediments at both holding temperatures (Table 3-24). For the SQ-1 sediment and the Tri-
Cities soil, none of the PCBs had mean concentrations that were significantly less than the Day 0
mean. With an overall CV<25%, rejection of the null hypothesis provides a measure of data
variability and validity to any potential decrease in concentration suggested by linear regression
(discussed below). Unlike the analysis of the PAH data, no PCB data exhibited a holding time
analysis with an overall CV>25% and a significant test. In fact, only the Housatonic River
sediment Aroclors and 5 Tri-Cities soil PCB congeners [8, 153 (at 4°C and -20°C) and 180 (at
4°C)] exhibited holding time analyses with mixed statistical analyses (CV<25% but a significant
t-test, or a CV>25% but a non-significant t-test). The other holding time analyses yielded data
that exhibited both an overall CV<25% and a non-significant t-test (Table 3-24) and; therefore,
these PCB concentrations must be considered stable over the 168 day period of the study.
The lack-of-fit to the linear model was significant for seven of the PCBs measured in all three
sediments (Table 3-25). The residuals for these analytes did not show a consistent U-shaped
pattern through time, and therefore, the lack-of-fit was assumed to be noise. Hence, the simple
linear model was used for all analytes, sediments, and holding temperatures. The slope
associated with the number of days held was negative and significantly different from zero for
both Aroclors measured in the Housatonic River sediment and for both holding conditions (Table
3-25). Neither of the slopes associated with the number of days held were significantly different
from zero for Aroclor 1254 measured in SQ-1 sediment. For the Tri-Cities soil, only PCB 153 (at
both holding temperatures) had a significant, negative slope while PCB 8 (at 4°C) exhibited a
significant positive slope. There was no consistent pattern between the three samples and the
behavior of the aroclors or PCB congeners.

The linear regression model's estimated lower confidence limit of the slope (£LCL) was utilized
to calculate a conservative holding time estimate (prior to extraction) for a 5%, 10% or 20%
decrease in concentration to occur for each Aroclor or PCB congener and storage temperature.
Based on the linear regression analysis, the PCBs sampled from the Housatonic River sediment
(aroclors) and the Tri-Cities soil (aroclors and congeners) had a minimum holding time of 65
days until a 5% decrease in the natural log concentration would be expected (Table 3-26). PCB
52 and 153 had the shortest holding times for both holding conditions. Only one of the PCBs
(PCB 8) had a positive estimated lower confidence limit on the slope (PLCL) and; thus, the
number of days until a given percentage decrease in concentration could not be calculated for the
4°C holding condition. For all but PCB 52, the holding time for the -20°C holding condition was
greater than the 4°C holding condition with the minimum holding time for a 5% decrease being
65 days for PCB 52. Given the prescribed SW-846 metric of CV<25% for replicate samples, the
shortest holding time for a 20% decrease in concentration was estimated to be 260 days, which is
18.5 times longer than the current SW-846 prescribed 14 days.

As a result of the wide variability in the slope estimate for Aroclor 1254 measured in the SQ-1
sediment (Table 3-25), the estimated numbers of days until a 10% decrease in natural log
concentration from the best-fit intercept was estimated as zero to one day. Confounding this wide
variability was the previously discussed concerns associated with SQ-1 Day 0 and Day 7
measurements that required surrogate correction. Even with surrogate correction; however, the
analyte's concentration appeared to be linked to extract age (Fig. 3-28). While it is believed that
data manipulation may have inserted bias into the values, it clearly reduced the variability of the
Day 0 data (prior to surrogate correction CV=33.7%, but after correction CV=0.6%). The
resulting tight data set placed inordinate dependence on Day 0 data that can be clearly seen in the
plotted data (Fig. 3-29). Because of these concerns the data for SQ-1 sediments were not
presented in Table 3-26. Even with these concerns; however, the overall CV (Table 3-24) for the
SQ-1 sediment aroclor data suggests that there is no substantive change in the aroclor
concentration over the life of the study (168 days).

Figure 3-29. Observed Aroclor 1254 concentration for SQ-1 sediment at both the 4°C and
-20°C holding temperature by holding time and associated Day 0
nonparametric bounds; there was no significant trend.
Plots of the observed concentration through time were compared to the nonparametric upper and
lower boundaries of the Day 0 concentration for the Housatonic River sediment and the Tri-
Cities soil (Fig. 3-30 to 3-40). All of the PCBs had observations that fell outside of the Day 0
nonparametric boundaries. Regression lines are shown for those holding time sequences that
exhibited a negative slope (Aroclor 1254 and 1260 - Housatonic River and PCB 153 - Tri-
Cities). The PCB 153 congener extracted from the Tri-Cities soil appears to decrease over time
(Fig. 3-30) as the data exhibited a statistically significant negative slope (Table 3-25), its CV was
slightly greater than 25% (28.1% for both holding temperatures), but the t-test was not
significant, and the plotted data remained (for the most part) within the nonparametric bounds.
Taken together, the statistical data suggests that there is a decrease in PCB 153 over the life of
the study. The regression model estimated that a decrease in PCB 153 concentration of 20%
would require 260 days (Table 3-26) which appears to be in agreement with the plotted data
(Fig. 3-30), but was beyond the duration of this study. With the exception of the Housatonic
River sediment Aroclors (Fig. 3-31 and 3-32; discussed below), the remaining plots show the
variability of the extraction data discussed previously, but also shows the stability of PCB
congeners and Aroclors though the holding time sequence of this study regardless of holding
temperature (Figs. 3-33 to Fig. 3-40).
The Housatonic River sediment Aroclor (1254 and 1260) data exhibited significant negative
slopes at both holding temperatures (Table 3-25). However, inspection of the data plots for these
Aroclors showed an anomaly that was difficult to explain (Fig. 3-31 and 3-32). For Aroclor 1254
the initial extractions (Day 0 and Day 7) had similar concentration means and distributions, but
concentrations at Day 14 had decreased to below the Day 0 lower bound and maintained that
concentration for the remaining 154 day time sequence (Fig. 3-31). While this behavior yielded a
statistically significant linear regression (Table 3-25), the plotted data suggests an extraction

or analysis error because of the sharp break between 7 and 14 days. An explanation for this
behavior; however, could not be discerned from a reevaluation of the raw data. Despite this
aberrant behavior the overall CV<25% suggests that the holding time sequence concentrations of
the Aroclor would be within replicate precision prescribed by SW-846 (Table 3-24); hence the
concentration did not change significantly during the 168 day study. This conclusion was
essentially the same as that arising from the regression analysis in that a 5% decrease in
concentration required 157 days; essentially the length of the study. The extract concentration
data for Aroclor 1260 behaved in a similar manner (Fig. 3-32) and yielded very similar
conclusions (Table 3-24 and 3-26).
3.2.2.3 PCB Holding Time Study- Conclusions: The objective of PCB extraction study was
to determine if significant loses of PCBs occurred when sediment/soil samples were stored at
either 4°C or -20°C for a period of 168 days. Samples from three field sites were examined. Of
the three Aroclors and 7 congeners that were quantified, there was no difference in the mean
concentration between samples stored at the two temperatures (Table 3-23). The minimum
estimated number of days required for Aroclors to decrease by 20% was 630 days (Aroclor 1254;
Housatonic River sediment) and 260 days for PCB 153 stored at 4°C (Table 3-26); both of these
time estimates are well beyond the currently prescribed 14 day MHT.

3.2.3 Pesticides
Concentrations of pesticides were characterized through time for each of four soils/sediments;
Housatonic River sediment, Sequim Bay (SQ-1) reference sediment, Tri-Cities soil, and
Bedford-1 soil and two holding temperatures (4°C and -20°C) (Appendix A, Descriptive
Statistics Tables A-l 1 to A-14). None of the analytes were analyzed in all four of the
sediments/soils. The pesticides that were characterized across time for each soil/sediment are
listed in Table 3-27. All of the observed concentrations were above 2*MDL except for
Housatonic River sediment concentrations for 4,4-DDD and SQ-1 sediment concentrations for y-
BHC (Table 3-27). The SQ-1 sediment had the lowest concentration of all pesticides with its
highest concentration being a-chlordane averaging 11 ng/g (dry weight). The Tri-Cities soil had
the highest a and y chloradane concentrations averaging about 6,000 ng/g while and the
Housatonic River sediments had the highest 2,4-DDT concentrations averaging 1100 ng/g.
As with the PAH and PCB extractions, the value of CV<25% is considered the allowable
variability between replicates for pesticide extraction. Table 3-27 shows the mean concentration
and CV of all Day 0 data accepted for statistical analysis (including potential statistical outliers)
and the across time CV for the data at 4°C and -20°C (i.e., all data across a time sequence except
for Day 0). The SQ-1 sediment exhibited Day 0 CVs>25% for most of the pesticides extracted
from this sediment (Table 3-27), but once the data were surrogate corrected (as with the PCB
Aroclor) the CV was reduced considerably (discussed below). The only other soil/sediment to
exhibit CV>25% was the Day 0 Housatonic River sediment 4,4-DDD, whose concentration was
< 2*MDL. Interestingly, the Bedford-1 soil Day 0 analyses suggested the same curious analysis
time dependence observed for the SQ-1 Aroclors (section 3.3.2.1). However, unlike the SQ-1
analyses, the Day 0 Bedford-1 pesticide data were below the CV<25% metric.
The results shown in Table 3-27 for the mean and CV of across time data (excluding Day 0 data)
for sediment held at 4°C and -20°C, can be viewed as an estimate of data variability. The
variability arising for the across time CV analysis is a combination of sample heterogeneity,
analytical precision, and the variability with time. Given the metric of CV<25%, much of the
data for a given time sequence (excluding Day 0), soil/sediment, and storage temperature could
be considered valid replicates regardless of holding time.
For the Housatonic River sediment, five observations from the -20°C holding temperature and
three for the 4°C holding temperature (8 out of 100 = 8%) were identified as extreme outliers
(observations greater than the 75th percentile plus 3 times the interquartile distance of the Day 0
data) and were removed from the analysis. For the SQ-1 analysis, 15 observations from the
-20°C holding temperature and 21 from the 4°C holding temperature out of 183 (20%) were
identified as extreme outliers. Because 20% of the data were considered extreme outliers and this
amount was greater than the limit of 10%, these data were not removed from the analysis. For
the Bedford-1 soil analysis, seven observations from the -20°C holding temperature and eight
from the 4°C holding temperature out of 84 (18%) were identified as extreme outliers. These
data were not removed from the analysis.

3.2.3.1 Surrogate Correction of SQ-1 Sediment Pesticide Extraction Data'. As with the
SQ-1 sediment PCB analyses, surrogate recovery for the SQ-lsediment pesticide results
generally increased with holding time (days to extraction; Fig. 3-41). Thus, the SQ-1 results were
surrogate corrected using either PCB 103 or PCB 198 based on their molecular weight (Table
3-28). Even though extracts were not held for more than 40 days, extracts older than 30 days
showed a reduced concentration (Figure 3-42). Those extracts held for more than 30 days were
from Day 0 and Day 7 sampling periods. Thus, for the statistical analysis, only extracts held for
less than 30 days were used, and the starting time of the experiment (Day 0) was moved to Day
14 data. The Bedford-1 soil pesticide results also showed an increase in the surrogate recovery
with holding time (Figure 3-43) and; thus, these data were surrogate corrected using the
surrogates listed in Table 3-28.
3.2.3.2 Statistical Analysis of Pesticide Extraction Data'. Once analyte extraction data for
all soils/sediments, storage temperatures, and holding time sequences were surrogate corrected as
necessary (SQ-1 and Bedford-1) and statistical outliers removed, data for a given soil and storage
temperature were pooled across time (0 to 168 days). The mean, standard deviation and CV were
calculated for the pooled data (Table 3-29). Strictly based on CV<25% as a measure of
acceptable replicate precision, the overall CV showed that only 12 out of the 40 holding time
sequence pooled data sets did not meet the CV metric. Two of the holding time sequences with
CV>25% exhibited concentrations at < 2MDL, namely, 4,4-DDD from the Housatonic River
sediment and y-BHC from the SQ-1 sediment. The remaining pooled data at CV>25% were
extracted from the SQ-1 sediment (5), Tri-Cities soil (2), and one from Bedford-1 sediment. The
remaining 28 holding time sequence studies all exhibit an overall CV<25% (Table 3-29), which
suggests that these data met the SW-846 prescribed criteria for replicate precision except for the
obvious fact that the data were collected over a period of 168 days.

A one-sample t-test of the null hypothesis Ho: the sample is from a population with the mean
equal to or greater than the Day 0 mean, was rejected for a total of 8 holding time sequence
studies (Table 3-29). Interestingly, only one holding time sequence exhibiting a significant t-test
also exhibited a CV>25% (i.e., Housatonic River sediment for 4,4-DDD held at 4°C), but this
pesticide holding time sequence had concentrations <2*MDL. The remaining 7 holding time
sequences presented conflicting statistical data; that is, they exhibited statistically significant t-
tests, but their overall CV was <25%. The Tri-Cities and Bedford-1 soils did not have any
pesticides that had mean concentrations that were significantly less than the Day 0 means.

Overall, 18 of 40 holding time sequences exhibited conflicting CV and t-test results; the series
either had CV<25% and significant t-tests (7 series), or CV>25% and non-significant t-tests
(1 Iseries) (Table 3-29). The 21 remaining holding time sequences exhibited CVs<25% and a
non-significant t-test (Table 3-29). For these 21 holding time sequences, the pesticide
concentrations did not change significantly over the 168 day life of the study. For the 18 holding
time sequences that exhibited conflicting CV and t-test statistics the potential for a small change
in concentration cannot be ruled out. However, the series that had an overall CV<25% essentially
exhibited variability that would fall within the current SW-846 prescribed replicate precision
acceptance.
The lack-of-fit to the linear model (using the natural log scale) was significant for 12 of the 40
pesticide holding time sequences measured in all sediments/soils at both holding temperatures
(Table 3-30). As with the PAH and PCB analysis, the pesticide residuals for the analytes did not
show a consistent U-shaped pattern through time and; therefore, the lack-of-fit was assumed to
be noise. Hence, the simple linear model was used for all analytes, sediments/soils, and holding
temperatures. The slope associated with the number of days held was negative and significantly
different from zero for 5 of the pesticide holding time series measured. Pesticides 4,4'-DDE from
Housatonic River sediment and 4,4-DDD from Bedford-1 soil had significantly decreasing
concentrations when held at both 4°C and -20°C, while 2,4-DDT from Housatonic River
sediment had significantly decreasing concentrations when held at -20°C. None of the slopes
associated with the number of days held were both negative and significantly different from zero
for pesticides measured in either SQ-1 sediment or Tri-Cities soil. There was no observable,
consistent pattern between the sediments/soils, temperature, and the behavior of the pesticides.

-------
Due to the wide variability in the slope estimate for many of the pesticides measured in the SQ-1
sediment [also observed for PCB Aroclors (section 3.3.2.2)], the estimated numbers of days until
a particular percent decrease (5%, 10%. or 20%) in natural log concentration from the best-fit
intercept was estimated as 0 to 24 days. Therefore, the SQ-1 sediment data were removed from
Table 3-31 because this calculation was dependent on Day 0 concentrations, which may have
been biased as a result of surrogate correction and analysis of extracts after 30 days but before 40
days. However, it can not be ignored that 14 out of 20 pooled SQ-1 pesticide data exhibited
corrected CVs<25%, which implies no significant change occurred for these analytes over the
168 day study.
The remaining pesticides sampled from the Housatonic River, Tri-Cities, and Bedford-1
sediments/soils had an estimated minimum holding time of 108 days or 217 days until a decrease
in the concentration of 10% or 20%, respectively, would be expected (Table 3-31). The
estimated time required for concentration decreases of 10% and 20% were 7.7 and 15.5 times
longer than the current SW-846 prescribed MHT for pesticides (14 days). Four of the pesticide
holding time sequences (all associated with the Tri-Cities soil; Table 3-31) exhibited positive
estimated slopes associated with the lower confidence limits (PLCL) and; thus, the number of days
until a given percentage decrease in concentration could not be calculated. However, all four of
the pesticide holding time sequences with positive slopes exhibited non-significant t-tests, two
[a-chlordane (4°C) and trans nonachlor (4°C)] had overall CVs<25%, and the other two [y-
chlordane (-20°C) and trans nonachlor (-20°C)] had overall CVs of 26.4 and 25.7, suggesting
that the concentrations associated with these four pesticide holding time sequences did not
change significantly over the 168 day life of the study.
Plots of the observed concentration through time were compared to the nonparametric upper and
lower boundaries of the Day 0 concentration (Fig. 3-44 to 3-56). The pesticide 4,4'-DDD from
the Housatonic River sediment and all pesticides from Tri-Cities soil fell within the Day 0
nonparametric bounds. All other pesticides had observations that were either greater or less than
these boundaries. Regression lines were included in the plots only when the slope was
significantly less than zero and negative.
Some of the Housatonic River sediment 4,4'-DDD concentrations were below 2*MDL and its
overall CV was >25% (regardless of holding temperature). An inspection of the plot (Fig. 3-44)
shows that the pesticide's concentration, while low, is apparently stable of the life of the study.
The other pesticides extracted from the Housatonic River sediment (4,4'-DDE, 2,4-DDT, and
4,4-DDT) exhibited greater variability, and at least several extreme outliers (Fig. 3-45, 3-46, and
3-47). The 4,4'-DDE and 2,4-DDT analyses yielded a significant and negative slope for
sediments held at -20°C for both pesticides and at 4°C for 4,4'-DDE. However, as can be seen
from the plots of both pesticides (Fig. 3-45 and 3-46), if the extreme outliers were removed from
the analysis, allowed the regression slope became significant and negative. Despite the outlier
data removal, the estimated time estimated for an observed 5% decrease in concentration of 4,4'-
DDE and 2,4-DDT was calculated to be a minimum of 60 days (Table 3-31); more than 4 times

behavior between 2,4-DDT (Fig. 3-46) and 4,4-DDT (Fig. 3-47) during the initial 84 days and
the final timed extraction at 168 days was nearly the same yet the outlier removal changed the
result from a significant regression line slope to a non-significant regression line slope. The 4,4-
DDT did not have a slope significantly different than zero. In the case of 4,4-DDT, the same 5%
decrease in concentration was estimated to require a minimum of 258 days.
Pesticides extracted from the SQ-1 sediment are presented in Figures 3-48 to 3-52 which
represent only five of the ten pesticides extracted from the SQ-1 sediment. The remaining plots
are presented in Appendix B. As previously discussed, the SQ-1 sediment pesticide data required
surrogate correction, which caused the T = 0 replicates to be very tightly centered on the mean
(note the narrow upper and lower bounds in Figs. 3-48 to 3-52). Despite the need for surrogate
correction and the low concentrations of all the SQ-1 extracted pesticides, the data are relatively
tight over the life of the study. Unlike the Housatonic River sediment data for 4,4'-DDE and 2,4-
DDT, outlier removal does not appear to have greatly effected the regression line slope of the
plotted data.

All the Tri-Cities soil extracted pesticides (a-, and y-chlordane, and trans nonachlor) holding
time sequences had non-significant t-tests; only y-chlordane (at -20°C) and trans nonachlor (at
-20°C) had overall CVs>25% (both pesticides CV=26%); and the regression slope was either
non-significant or positive (Table 3-30). From these statistical results it is clear why the Tri-
Cities soil extracted pesticide data fell within the Day 0 nonparametric bounds (Fig. 3-53 to
3-55) indicating no significant trends in pesticide concentrations through time.
Of the three Bedford-1 soil extracted pesticides, only 4,4-DDD, and 4,4-DDT are plotted below
(Fig. 3-56 and 3-57) while the plot for 2,4-DDD is presented in Appendix B. The 4,4-DDD
extract data did have a significant and negative slope at both holding temperatures, its CVs<25%
and the t-test was not significant (Table 3-30). Inspection of the plotted data (Fig. 3-56) shows
the slope to be minimal, which is reflected in the minimum estimated time (146 days) required to
observe a 5% decrease in concentration (Table 3-31). The data plotted for the Bedford-1 soil
extracted 4,4-DDT were surrogate corrected and exhibited the numerous outliers that were not
removed for analyses because of the 18% outlier percentage. Even with the outliers accounted
for, there was essentially no change in 4,4-DDT concentration over the life of the study.
3.2.3.3 Pesticide Holding Time Study- Conclusions: The objective of the pesticide
extraction study was to determine if significant loses of chlorinated pesticides occurred when
sediment/soil samples were stored at either 4°C or -20°C for a period of 6 months. Samples from
four field sites were examined. Of the 12 compounds that were quantified, there was no

difference in the mean concentration between samples stored at the two temperatures (Table
3-27). The estimate for the number of days for pesticides to decrease by 20% is 217 days for
4,4-DDT stored at 4°C and greater than 217 days for other compounds in three sediment/soils
(Table 3-31). The data for SQ-1 samples could not be evaluated for stability because the initial
concentrations were significantly lower than the concentrations in the stored samples.
3.3 Acid Extraction of Metals
The six month holding time between sample collection and extraction/analysis is a substantial
time period. The larger issue of drying a solid matrix (i.e., a soil or sediment) is often questioned.
The extraction method allows the sample to be dried, but drying is not required. However,
sample homogeneity is typically more easily achieved with dried and sieved materials.
This study utilized a soil and sediment to determine if extractable concentrations of As, Cu, Pb,
and Zn changed with time, and the impact of air drying the sample. The soil and sediment
utilized in this study exhibited very different pHs and particle size distributions (Table 3-32).
3.3.1 Statistical Analysis of Metals Extraction
Metals (As, Cu, Pb, and Zn) were characterized through time for Sinclair river sediment and
Wilmington soil and for holding conditions (moist and air-dried) (Appendix A Descriptive
Statistics Tables A-15, A-16). The Sinclair sediment had the highest concentrations of Cu and Zn
averaging at least 487 |j,g/g and 448 ng/g, respectively (Table 3-33). The Wilmington soil had
the highest concentrations of As and Pb averaging at least 62 (ig/g and 5653 |j,g/g, respectively
(Table 3-33). Within replicate (Day 0) CVs ranged from 6.4% (As) to 15.9% (Pb) for the Sinclair
River sediment.

The CVs ranged from 4.8% (As) to 8.3% (Pb) for the Wilmington soils. Two observations from
Day 0 were removed from the analysis, one observation for Pb from the Sinclair sediment and
one observation for Zn from the Wilmington soil because of possible sample contamination.
Data for each holding time sequence were pooled (Table 3-33). Only one pooled data set
exhibited a CV>20% (i.e., Sinclair River sediment for Pb held in the dry condition). The
remaining data sets exhibited fairly tight CVs across time ranging from 5.6 to 15.8. The pooled
CV data suggests that no chemically significant change in concentration occurred during the 12
month time sequence; further, the pooled data exhibited no clear cut difference between moist or
dry sample handling techniques. The holding time sequence pooled CV data (with the exception
of the Sinclair River sediment Pb, air-dried series) are well within the SW-846 prescribed
replicate precision metric of CV<20% for the hot acid metal extraction from soils/sediments.
A one-sample t-test of the null hypothesis Ho: the sample is from a population with the mean
equal to or greater than the Day 0 mean, was rejected for the dry Sinclair sediment for As and Zn
87
-------
(Table 3-33). The remaining 14 data sets failed to reject the null hypothesis. For those holding
time sequences that exhibited CV<20% and a non-significant t-test, the extractable
concentrations did not changed significantly over the 12 month period of this study. Importantly,
Pb extracted from the air-dried Sinclair sediment exhibited a non-significant t-test, but a pooled
CV>20%. In contrast, Zn and As extracted from the air-dried Sinclair River sediment exhibited a
pooled CV<20%, but a significant t-test. These apparent contradictory statistics can be
reconciled by inspection of the data plots (Figs. 3-58 to 3-60).
The Sinclair River sediment As plot (Fig. 3-58) showed As concentrations to be low and the Day
0 mean to be very tightly focused around 22.5 |j,g/g sediment. In contrast, the concentration for
the dry sediment at 217 days was the lowest value measured and was outside the Day 0
nonparametric bounds. In addition, the 392 day dry sediment As concentration was also low.
These two holding time data sets were responsible for the As significant t-test. Likewise, the
extracted Zn concentration plot for the air-dried Sinclair River sediment (Fig. 3-58) exhibited a
similar pattern at 392 days; the mean of these data were well outside the Day 0 mean (470 |j,g/g
sediment) which was sufficient to reject the t-test null hypothesis. The Pb extraction from the air-
dried Sinclair River sediment (Fig. 3-60), on the other hand, exhibited only one data set whose
mean (253 |j,g/g sediment) that was well outside of the Day 0 mean (164 |j,g/g sediment) and
resulted in an overall CV>20%, but a non-significant t-test. It seems clear that despite the
conflicting statistics the extractable concentrations of As, Pb, and Zn from the air-dried Sinclair
sediment did not change significantly over the 392 day period of this study.
The lack-of-fit to the linear model was significant only for As from the wet Sinclair River
sediment (Table 3-34). The residuals; however, did not show a consistent U-shaped pattern
through time suggesting that a parameter for curvature was not needed in the model. Therefore,
the simple linear model was used for all sediments and holding temperatures. Except for Zn in
both dry sediments, the slope associated with the number of days held was not significantly
different from zero for any of the remaining metals and sediments (p > 0.07; Table 3-34). For all
metals and sediments; however, the absolute value of the estimated slope was very small
(<0.001) suggesting that a significant decrease was not occurring within the 392 day time frame
of the study.
The estimated numbers of days until a 5% decrease in metal concentration from the estimated
intercept would be observed were all greater than 177 days; a 20% decrease in concentration was
estimated to require 709 days for As (Table 3-35) which had the least amount of time required
for a 20% change to be detected. Zn from the Wilmington dry sediment had a positive estimated
lower confidence limit on the slope (PLCL) and; thus, the number of days until a given percentage
decrease in concentration could not be calculated. Except for Pb in both matrices and Cu in
Wilmington soil, it appeared that the holding times for matrices held in moist state were longer
than the holding time for sediment held in an air-dried state. However, these estimates were
made from data whose slopes were not significantly different from zero and no difference was
observed between wet and air-dried samples. Hence, the estimated time required for a given
increase was directly related to the data's variability. The conservative estimate; however, is the
smaller number of days.

Figures 3-61 to 3-65 show the observed concentration through time and the nonparametric upper
and lower boundaries of the Day 0 concentration for the Wilmington soil As, Cu, Pb, and Zn,
and the Sinclair sediment Cu. All observations fell within the Day 0 nonparametric boundaries.
Thus, the concentration of metals in the two sediments held either wet or dry did not decline
significantly over the 12 month life of the study.
3.3.2 Metal Extraction Holding Time Study - Conclusions
The objective of the metal hot acid extraction study was to determine if the concentrations of As,
Cu, Pb, and Zn exhibited significant decreases when stored at either 4°C in either an air-dried or
field moist state for a period of 12 months. None of the metals exhibited a statistically significant
decrease in extractable concentration over the 392 day test period. In addition, none of the metal
concentration data, as a function of time, exhibited a slope statistically different from zero.
Hence, none of the metal concentrations, regardless of matrix or storage condition decreased
during the life of the study. Estimates of stability suggest that a 20% decrease in concentration
would occur most rapidly for As but would require 709 days or about 3.9 times longer than the
current MHT.

Section 4
Conclusions
The extractable concentration of Cr(VI) was investigated in six soils/sediments. Of the six soils
studied, five exhibited no or only limited influence of holding time prior to extraction for the 224
days of this study regardless of the holding condition (4°C or -20°). The estimated number of
days until a 5% decrease in natural log concentration from the estimated intercept would be
observed was greater than 140 days for all sediment/soils tested.
The sixth Cr(VI) contaminated soil exhibited poor recovery (<5%) of the matrix spikes from the
outset of the study. Standard additions of Cr(VI) added to the extract solutions after filtration and
pH adjustment were not detectable by SW-846 Method 7196A, Chromium, Hexavalent
(colorimetric). Regardless of the Cr(VI) standard addition, a constant, lowUV/Vis absorbance
(-0.25 au) was measured at the prescribed 540 nm wavelength. However, the same low
absorbance was observed whether the extract absorbance was measured directly without pH
adjustment and addition of diphenylcarbazide with pH adjustment only, or as prescribed in SW-
846 Method 7196 A. These results were directly related to the high DOC content of the extracts,
which was high enough that its absorbance was significantly above background (-0.02 au).
Reduction by the dissolved Fe2+ and/or the quinine character of the DOC reduced the Cr(VI)
added to the system to Cr(III). It is likely that Cr(VI) was not associated with this soil and the
prescreen positive Cr(VI) results were the result of high levels of extracted DOC.
The stability of the Cr(VI) soils/sediment extracts over the 56 day holding period was far beyond
the MHT of 24 hrs specified in SW-846. Even with the noted variability between replicates, the
CV across time was low with the extracts stored at 4°C exhibiting a maximum CV of 3%. When
extracts were stored at 20°C, the maximum CV was substantially greater (8%). These data
demonstrate that for the soil/sediment extracts investigated, there was no or only very limited
change in Cr(VI) concentration within the 56-day time frame. While we can not definitively
demonstrate or delineate the cause of observed differences between the two storage regimes, it is
well known that lower temperatures slow both microbial and chemical processes. While these
studies strongly demonstrate that when extract stability is present at "Day 0" (that is, the matrix
and laboratory control samples are within the specified range), it is likely that the stability of the
extract will last considerably longer than the SW-846 specified MHT. However, because of the
chemical nature of the extract and the analysis, it advisable that sample analysis be completed as
soon as possible.
The results of the Cr(VI) study suggest that the recoveries of the control and matrix spikes are
key to determining stability of Cr(VI) in the solid materials to be extracted and the extracts
themselves. In all cases, when the recovery of the matrix spike and control samples was good
(within acceptable parameters), the stability of Cr(VI) in the sediment/soil and extract solutions
(stored under proper conditions) appear to be longer than the current SW-846 specified MHT.

For the 17 PAH compounds that were quantified in three different soils/sediments, a holding
time of 100 days at either 4°C or -20°C would result in not more than a 20% decrease in PAH
concentration. Importantly, there is considerable variability in the estimated holding times for
different compounds and in different soils/sediments. The major consideration in sediment
holding time appears, from these studies, to be the ring number (or molecular weight) of the
PAH of interest.
The Eagle Harbor soil was collected from a creosote treatment site and contained the greatest
number of PAHs. This was the only soil/sediment that appeared to have significant loss to PAHs
for samples stored at 4°C refrigerated compared to frozen at -20°C. Compounds with relatively
low molecular weights, acenaphthene, fluorene, dibenzothiophene, phenanthrene, and anthracene
extracted from the soil held at 4°C were estimated to lose 5% of their concentration in as little as
23 days and 20% in as few as 92 days. The minimum calculated number of days for a 5% and
20% loss in concentration of these same five PAHs was 106 days and 424 days, respectively,
when the soil was held at -20°C. Our work is supported by studies of the stability of PAHs in
contaminated soil by Rost et al. (2002) who also observed significant losses of the lower
molecular weight compounds stored refrigerated compared to no significant losses for soil stored
frozen for a six week period. Their conclusion was that microbiological degradation was the
cause for the loss because PAH concentrations in samples treated with sodium azide (a
preservative biocide) did not change for the entire 3 month experiment.
The PAH results for the SQ-1 sediment and Bedford-1 soil exhibited none of the holding
temperature versus molecular weight results seen in the Eagle Harbor soil. However, the
minimum holding times for a 5% and 20% decrease in PAH concentrations for the SQ-1
sediment was 24 days and 99 days, respectively. The Bedford-1 soil minimum calculated holding
times for 5% and 20% PAH concentration decreases was 48 days and 195 days, respectively.
Given the SW-846 prescribed replicate precision metric of CV<25%, the shortest number of days
estimated for a 20% decrease (92 days) is 6.6 times longer than the current SW-846 MHT (14
days). Also, the results of the Eagle Harbor soil and those of Rost et al., (2002) suggest that a
holding temperature of-20°C seems appropriate regardless of the PAH under investigation.
For the three PCB Aroclor mixtures and the seven congener concentrations that were quantified
in three different soils/sediments remained fairly stable throughout the study. The minimum
estimated number of days required for Aroclors to decrease by 20% was 630 days (Aroclor
1254) and 260 days for PCB 153 stored at 4°C (Table 3-26). Both of these time estimates are
well beyond the currently prescribed SW-846 MHT of 14 days.
An indication of the stability of the PCBs in the three soil/sediments was the very small
difference in the mean concentration for all data across time at the two different storage
temperatures. In almost every case, the mean concentrations for the -20°C samples were slightly
greater, about 10% or less, than for the 4°C mean concentrations. This could be interpreted that
about 10% more PCBs are lost during 168 day storage at 4°C than at -20°C. The difference
between the "overall means" for two different temperatures similarly showed that storage for 168
day in a refrigerator resulted in not more than about 10% loss compared to freezer storage. Given
the 25% CV precision metric prescribed in SW-846, it is unlikely that this difference could be
accurately quantified.

The pesticides sampled from the Housatonic River, Tri-Cities, and Bedford-1 sediments/soils
had a minimum holding time of 108 days and 217 days until a 10% or 20%, respectively,
decrease in the concentration would be expected. The estimated time required for concentration
decreases of 10% and 20% were 7.7 and 15.5 times longer than the current SW-846 prescribed
MHT for pesticides (14 days). Due to the wide variability in the slope estimate for many of the
pesticides measured in the SQ-1 sediment [also observed for PCB Aroclors], the estimated
numbers of days until a 10% decrease in natural log concentration from the best-fit intercept was
estimated as 0 to 24 days. While the SQ-1 sediment pesticide holding time estimates were not
calculated because of the Day 0 data required surrogate correction, it can not be ignored that 14
out of 20 pooled SQ-1 pesticide data exhibited corrected CVs<25%, which implies no significant
change occurred for these analytes over the 168 day study. For the 10 pesticides that were
quantified in four different soil/sediments, a holding time of 217 days at 4°C and 299 days at
-20°C would result in not more than a 20% decrease in concentration, which is far greater than
the currently prescribed SW-846 MHT (14 days). There was no observable, consistent pattern
between the sediments/soils, storage temperature, and the pesticide concentrations.
Extractable metal concentrations were not affected significantly by a holding time of up to 392
days or by air drying of the soils. Only one pooled data set exhibited a CV>20%, which is the
current SW-846 precision metric for hot acid extraction of metals. However, CV>20% was
found to be the result of one holding time data set that was well outside the Day 0 mean. The
remaining data sets exhibited fairly tight CVs across time ranging from 5.6 to 15.8%. The CV
data suggests that no chemically significant change in concentration occurred during the holding
time sequence and the pooled data exhibited no clear cut difference between moist or dry sample
handling. These results suggest that it would take a minimum of 709 days before the acid-
extractable As, Cu, Pb, or Zn concentration would be reduced by 20%.

Chromate [Cr(VI)] Soil Extract Holding Time
Chromate [Cr(VI)] extract holding time data for soil extracts from 125A,
125B, 125C, and 126D
The laboratory control sample (LCS), soluble (K2Cr2O7) and insoluble
(PbCrO4) spikes, and the extract (K2Cr2O7) spike are listed in red for each
extraction along with the permissible QA/QC range. The soluble and
insoluble spike solutions were original to the initial extraction, but were
carried through the entire extract storage study as an additional check. The
solution spike and LCS were produced at each analysis point in this study.
