EXECUTIVE SUMMARY
A study was performed to validate proposed method SW-846 8327. Data from eight labs, which fit
quality assurance guidelines, was used in the statistical analysis. The method was validated for 24 per-
and polyfluorinated alky substances (PFAS) analytes and 19 surrogates. Four media were tested: reagent
water, surface water, groundwater, and wastewater effluent. The samples tested included blanks (no
PFAS), low spikes (60 ng/1), and high spikes (200 ng/1). The labs each analyzed five replicates for each
media and spike level.
The results were statistically analyzed for accuracy using the recovery and for precision using the relative
standard deviation. The laboratory results were analyzed for each analyte and surrogate separately as well
as for each lab, media, and spike level. The lab results were then compiled to provide across lab results.
The results were also compiled across labs, spike levels, and analytes to determine if the results differed
between media. The results were also compiled across labs, media, and analytes to determine if the results
differed between spike levels. The results were also compiled across labs, media, and spike levels to
determine if the results differed between analytes and surrogates. Finally, an intra-laboratory analysis was
performed.

1 INTRODUCTION
1.1 Analytical Methods
The validation study was undertaken to determine if multiple laboratories could achieve the necessary
accuracy and precision of draft method SW-846 8327, analysis of Analysis of Poly and Perfluorinated
Alkyl Substances (PFAS) in Waters. The analysis was performed in four media: reagent water, surface
water, groundwater, and wastewater effluent. The method is for 24 target PFAS and 19 surrogate PFAS.
Each participating laboratory was asked to analyze five replicates each of blank samples, low-spike
samples, and high-spike samples for all target and surrogate PFAS in all four media. The fifteen samples
per media (five blank, five low-spike, and five high-spike) were assigned random sample numbers. To
summarize, the labs were asked to analyze a total of 60 samples: five replicates for each three spike levels
for each four media. The labs were not blinded to media, as it was considered difficult to blind the
laboratory analysts to wastewater effluent compared to reagent water, and possibly surface water and
groundwater. To prevent bias in analysis order, all 60 samples per lab were assigned a random analysis
order, and the participating laboratories were asked to analyze in that order. The random analysis order
assignment was independently done for each lab, so each lab analyzed the samples in the different order
from the other labs.
The analysis results were statistically analyzed to determine if they met the necessary performance
measures. A total of eight laboratories were used for the analysis. Four laboratories from the internal
validation study were used. These laboratories are designated as Labs 2, 4, 5, and 6. The number was
randomly assigned to participating labs at the beginning of the internal study. Four laboratories from the
external validation study were used. These laboratories are designated as labs 10, 11, 12, and 16. The
number was randomly assigned to participating labs at the beginning of the external study. The data from
four laboratories, who returned analysis results, were not used due to deviations from the method or
multiple calibration failures. More detailed discussion of the reasons for the exclusion of these
laboratories from the statistical analysis is given in Appendix E. Other laboratories were initially part of
the study but did not return results in the needed timeframe. Of the results from included eight
laboratories, only one sample, a low spiked waste water sample from lab 10, was not used in the statistical
analysis because the sample results did not meet quality control measures.
1.2 Statistical Methods
All statistics were performed in SAS version 9.4 (TS1M1) (SAS Institute, Cary, NC). Data was imported
into SAS from Microsoft Excel. Statistics were calculated through a combination of PROC MEANS and
PROC UNIVARIATE. Tables presented in this report were generated in SAS and exported to Excel.
Graphs from generated in SAS using PROC SGPLOT.
1.3 Performance Measures
Numerous statistical measures are used to determine if the results met the necessary accuracy and
precision. Accuracy signifies how close a measurement is to the real value. The accuracy is based on the
recovery. The recovery is the percentage of the actual spiked concentration that was measured. The
precision is based on the relative standard deviation. Precision signifies how close repeated measurements
are to each other.

1.3.1 QAPP Specified Performance Measures
For several reported analysis, the arithmetic mean is used. The arithmetic mean is the sum of a set of
measurements divided by the number of measurements. The formula is provided below:
i=i
Where x = mean, n = number of measurements, and Xj = the measurements.
Background was calculated for the target analytes before calculating the several statistics. The
background was calculated as the mean of the measured concentration for the blank replicates for each
analyte for each media for each laboratory. The background was then subtracted from each measured
concentration to give a modified concentration, as follows:
* 	 	
xi — xi — xblank
This modified concentration was used for numerous statistical tests including the recovery for target
analytes.
The percent recovery of the analyte was calculated differently for the target analytes and the surrogates.
The percent recovery of the surrogates was calculated as follows:
Recovery(%) = —-— x 100
xspike
Where xspike = the actual spike concentration. The percent recovery of the target analytes was calculated
as follows:
X*
Recovery(%) = —-— x 100
xspike
According to the Quality Assurance Project Plan (QAPP), a recovery between 70% and 130% was
considered acceptable. Thus, in the report, if the recovery of a sample or the median recovery of a dataset
was between 70% and 130%, it was declared acceptable.
The standard deviation measures the variability between repeated measurements and is calculated as
follows:
ZF=i(xi-x)
The relative standard deviation measures the variability between repeated measurements compared to the
mean of the repeated measurements and is calculated as follows:
SD
RSD = —X 100
x
A relative standard deviation less than 50% was considered acceptable according to the Quality
Assurance Project Plan (QAPP). Thus, in the report, if the relative standard deviation of a dataset was less
than 50%, it was declared acceptable.

To determine the overall accuracy of the measurements, the median of the recovery was calculated. The
median was used rather than the mean in case the measurements did not have a normal distribution. The
median is also less impacted by outliers than the mean. To calculate the median, the recoveries were first
ordered from smallest to largest. For an odd number of measurements, the median is the middle number.
That is, if there are n measurements, and n is odd, then the median is the [(n+l)/2]th measurement. If n is
even, then the median is arithmetic average of the middle two measurements.
The lower and upper 95% limits were calculated on the median recovery to indicate the range of the
confidence as the true median. The lower 95% confidence limits is given by
n 1.96Vn . . , .
	th ranked value.

2 ANALYTE AND SURROGATE RESULTS
The results of the laboratory analysis are first discussed for each target analyte then for each surrogate
analyte. The results for the blanks, low spikes, and high spikes are discussed. Tables displaying all the
calculated statistics are given in Appendix A. Graphs displaying the measured concentrations and also the
recoveries for each target analyte and surrogate analyte are given in Appendix B. Reference lines are
presented on the measured concentrations graph indicating the spike levels for the analytes. Reference
lines are presented on the recovery graphs indicating 70% and 130%, the acceptable limits for recovery.
Because of outliers with many analytes that compressed the recovery graphs, for several analytes, two
recovery graphs are presented. Each analyte has a recovery graph is set with a minimum recovery of 0%
and a maximum recovery of 250%. Some analytes have a second recovery graph with no maximum
recovery limit so that all outliers are shown.
2.1 Perfluorotetradecanoic acid (PFTreA)
The measurements and recoveries combined for all labs are presented in Figures B-l and 2. Overall, the
results are good, but a few high outliers exist that skew the results. The interquartile range of all
recoveries are within the acceptable limits.
Results of the blank samples are given in Table A-l. One lab reported a concentration for each media for
PFTreA in the blank samples. Lab 11 reported a concentration in at least one sample of all media. The
highest reported concentration across the media was 30.1 ng/1.
The results of the low spike samples are given in Table A-44. Of the 159 low spike samples (only 39
wastewater), 29, 30, 31, and 27 samples have acceptable recovery in the groundwater, reagent water,
surface water, and wastewater, respectively. The median recovery for groundwater was unacceptable for
lab 4 (too low). The median recovery for reagent water was unacceptable for lab 2 (too low) and lab 16
(too high). The median recovery for surface water was unacceptable for lab 2 (too low) and lab 12 (too
low). The median recovery for wastewater was unacceptable for lab 2 (too low), lab 4 (too low), and lab
16 (too high). With a spike level of 60.0 ng/1, the lowest modified concentration across the media was
19.6 ng/1, and the highest modified concentration across the media was 103.0 ng/1. All labs had acceptable
RSD in all media. With the exception of a few individual lab data sets, the data were normally distributed
including when combined across all labs. Overall for all media, t-tests indicate that confidence is low the
measured concentrations reported by the individual labs are the same as the true spiked concentration
with just a few exceptions. For two to three labs per media, t-tests indicate that there is reasonable
confidence the reported measured concentrations are the same as the true spiked concentration. However,
it was not consistent across media as to which labs had reported measured concentrations that were or
were not the same as the true spiked concentration. Lab 5 though had results with consistently good
confidence of being equal to the true values.
The results of the high spike samples are given in Table A-87. Of the 160 high spike samples, 37, 37, 36,
and 34 samples have acceptable recovery in the groundwater, reagent water, surface water, and
wastewater, respectively. The median recovery for wastewater was unacceptable for lab 2 (too low). With
a spike level of 200.0 ng/1, the lowest modified concentration across the media was 110.4 ng/1, and the
highest modified concentration across the media was 317.8 ng/1. All labs had acceptable RSD in all
media. With the exception of a few individual lab data sets, the data were normally distributed including
when combined across all labs except for groundwater and surface water. Overall for all media, t-tests
indicate that confidence is low the measured concentrations reported by the individual labs are same as
the true spiked concentration with just a few exceptions. For two to three labs per media, t-tests indicate
-------

that there is reasonable confidence the reported measured concentrations are the same as the true spiked
concentration. However, it was not consistent across media as to which labs had reported measured
concentrations that were or were not the same as the true spiked concentration. Labs 4 and 16 though had
results with good confidence of being equal to the true values for three of four media.
2.2 Perfluorotridecanoic acid (PFTriA)
The measurements and recoveries combined for all labs are presented in Figures B-3 and 4. Overall, the
results are good, but a few high outliers exist that skew the results. The interquartile range of all
recoveries are within the acceptable limits.
Results of the blank samples are given in Table A-2. At least one lab reported a concentration for each
media for PFTriA in the blank samples. Lab 11 reported a concentration in at least one sample of all
media. Lab 5 reported a concentration in at least one sample surface water and wastewater. The highest
reported concentration across the media was 24.4 ng/1.
The results of the low spike samples are given in Table A-45. Of the 159 low spike samples (only 39
wastewater), 32, 32, 33, and 30 samples have acceptable recovery in the groundwater, reagent water,
surface water, and wastewater, respectively. The median recovery for groundwater was unacceptable for
lab 5 (too high). The median recovery for surface water was unacceptable for lab 2 (too low). The median
recovery for wastewater was unacceptable for lab 16 (too high). With a spike level of 60.0 ng/1, the lowest
modified concentration across the media was 24.7 ng/1, and the highest modified concentration across the
media was 122.8 ng/1. With the exception of a few individual lab data sets, the data were normally
distributed including when combined across all labs except for groundwater and waste water. Overall for
groundwater, reagent water, and surface water, t-tests indicate that confidence is low the measured
concentrations reported by the individual labs are the same as the true spiked concentration with just a
few exceptions. For wastewater, t-tests indicate that five of the labs reported measured concentrations that
are the same as the true spiked concentration. For one to five labs per media, t-tests indicate that there is
reasonable confidence the reported measured concentrations are the same as the true spiked concentration.
However, it was not consistent across media as to which labs had reported measured concentrations that
were or were not the same as the true spiked concentration. Lab 11 though had results with good
confidence of being equal to the true values for three of four media.
The results of the high spike samples are given in Table A-88. Of the 160 high spike samples, 35, 35, 36,
and 34 samples have acceptable recovery in the groundwater, reagent water, surface water, and
wastewater, respectively. The median recovery for reagent water was unacceptable for lab 5 (too high).
The median recovery for wastewater was unacceptable for lab 2 (too low). With a spike level of 200.0
ng/1, the lowest modified concentration across the media was 119.8 ng/1, and the highest modified
concentration across the media was 300.5 ng/1. With the exception of a few individual lab data sets, the
data were normally distributed including when combined across all labs. Overall for all media, t-tests
indicate that confidence is low the measured concentrations reported by the individual labs are the same
as the true spiked concentration with just a few exceptions. For two to four labs per media, t-tests indicate
that there is reasonable confidence the reported measured concentrations are the same as the true spiked
concentration. However, it was not consistent across media as to which labs had reported measured
concentrations that were or were not the same as the true spiked concentration. Labs 4 and 11 though had
results with good confidence of being equal to the true values for three of four media.

2.3 Perfluorododecanoic acid (PFDoA)
The measurements and recoveries combined for all labs are presented in Figures B-5 and 6. Overall, the
results are good, but several high outliers and a few low outliers exist that skew the results. The
interquartile range of all recoveries are within the acceptable limits.
Results of the blank samples are given in Table A-3. At least one lab reported a concentration for each
media for PFDoA in the blank samples. Lab 11 reported a concentration in at least one sample of all
media. The highest reported concentration across the media was 21.8 ng/1.
The results of the low spike samples are given in Table A-46. Of the 159 low spike samples (only 39
wastewater), 33, 33, 35, and 28 samples have acceptable recovery in the groundwater, reagent water,
surface water, and wastewater, respectively. The median recovery for groundwater was unacceptable for
lab 16 (too high). The median recovery for wastewater was unacceptable for lab 4 (too low) and lab 16
(too high). With a spike level of 60.0 ng/1, the lowest modified concentration across the media was 28.8
ng/1, and the highest modified concentration across the media was 115.3 ng/1. All labs had acceptable
RSD in all media. With the exception of a few individual lab data sets, the data were normally distributed,
but when combined across all labs, the data was not normally distributed except for surface water. Overall
for all media, t-tests indicate that confidence is low the measured concentrations reported by the
individual labs are the same as the true spiked concentration for more than half the labs. For three to four
labs per media, t-tests indicate that there is reasonable confidence the reported measured concentrations
are the same as the true spiked concentration. However, it was not consistent across media as to which
labs had reported measured concentrations that were or were not the same as the true spiked
concentration. Labs 5 and 11 though had results with good confidence of being equal to the true values
for all four media.
The results of the high spike samples are given in Table A-89. Of the 160 high spike samples, 35, 36, 36,
and 36 samples have acceptable recovery in the groundwater, reagent water, surface water, and
wastewater, respectively. The median recovery for groundwater was unacceptable for lab 16 (too high).
The median recovery for reagent water was unacceptable for lab 16 (too high). The median recovery for
surface water was unacceptable for lab 16 (too high). The median recovery for wastewater was
unacceptable for lab 16 (too high). With a spike level of 200.0 ng/1, the lowest modified concentration
across the media was 132.7 ng/1, and the highest modified concentration across the media was 331.4 ng/1.
All labs had acceptable RSD in all media. While the data from individual labs tended to be normally
distributed, the data when combined across all labs were not normally distributed except for surface
water. Overall for all media, t-tests indicate that confidence is low the measured concentrations reported
by the individual labs are the same as the true spiked concentration. However, for about two or four labs
per media, t-tests indicate that there is reasonable confidence the reported measured concentrations are the
same as the true spiked concentration. However, it was not consistent across media as to which labs had
reported measured concentrations that were or were not the same as the true spiked concentration. Labs 4
and 11 though had results with good confidence of being equal to the true values for all four media.
2.4 Perfluoroundecanoic acid (PFUnA)
The measurements and recoveries combined for all labs are presented in Figures B-7 and 8. Overall, the
results are good with just a few high outliers exist that skew the results. The interquartile range of all
recoveries are within the acceptable limits.
-------

Results of the blank samples are given in Table A-4. At least one lab reported a concentration for each
media for PFUnA in the blank samples. Lab 11 reported a concentration in at least one sample of all
media. The highest reported concentration across the media was 25.1 ng/1.
The results of the low spike samples are given in Table A-47. Of the 159 low spike samples (only 39
wastewater), 36, 36, 36, and 36 samples have acceptable recovery in the groundwater, reagent water,
surface water, and wastewater, respectively. The median recovery was acceptable for all labs and all
media. With a spike level of 60.0 ng/1, the lowest modified concentration across the media was 37.7 ng/1,
and the highest modified concentration across the media was 97.7 ng/1. All labs had acceptable RSD in all
media. While the data from individual labs tended to be normally distributed, the data when combined
across all labs were not normally distributed. Overall for all media, t-tests indicate that confidence is low
the measured concentrations reported by the individual labs are the same as the true spiked concentration.
However, for about three to five labs per media, t-tests indicate that there is reasonable confidence the
reported measured concentrations are the same as the true spiked concentration. However, it was not
consistent across media as to which labs had reported measured concentrations that were or were not the
same as the true spiked concentration.
The results of the high spike samples are given in Table A-90. Of the 160 high spike samples, 36, 36, 39,
and 35 samples have acceptable recovery in the groundwater, reagent water, surface water, and
wastewater, respectively. The median recovery for groundwater was unacceptable for lab 16 (too high).
The median recovery for reagent water was unacceptable for lab 16 (too high). The median recovery for
wastewater was unacceptable for lab 16 (too high). With a spike level of 200.0 ng/1, the lowest modified
concentration across the media was 144.7 ng/1, and the highest modified concentration across the media
was 312.0 ng/1. All labs had acceptable RSD in all media. While the data from individual labs tended to
be normally distributed, the data when combined across all labs were not normally distributed except for
surface water. Overall for all media, t-tests indicate that confidence is low the measured concentrations
reported by the individual labs are the same as the true spiked concentration. However, for about two to
four labs per media, t-tests indicate that there is reasonable confidence the reported measured
concentrations are the same as the true spiked concentration. However, it was not consistent across media
as to which labs had reported measured concentrations that were or were not the same as the true spiked
concentration. Lab 4 though had results with good confidence of being equal to the true values for all four
media.
2.5 Perfluorodecanoic acid (PFDA)
The measurements and recoveries combined for all labs are presented in Figures B-9 and 10. Overall, the
results are good with just a few high outliers and a low outlier. The interquartile range of all recoveries
are within the acceptable limits.
Results of the blank samples are given in Table A-5. At least one lab reported a concentration for each
media for PFDA in the blank samples. Lab 11 reported a concentration in at least one sample of all media.
Two other labs reported a concentration in at least one wastewater sample. The highest reported
concentration across the media was 34.0 ng/1.
The results of the low spike samples are given in Table A-48. Of the 159 low spike samples (only 39
wastewater), 38, 36, 38, and 35 samples have acceptable recovery in the groundwater, reagent water,
surface water, and wastewater, respectively. The median recovery was acceptable for all labs and all
media. With a spike level of 60.0 ng/1, the lowest modified concentration across the media was 33.2 ng/1,
-------
8
and the highest modified concentration across the media was 107.0 ng/1. All labs had acceptable RSD in
all media. While the data from individual labs tended to be normally distributed, the data when combined
across all labs were not normally distributed except for surface water and wastewater. Overall for all
media, t-tests indicate that confidence is low the measured concentrations reported by the individual labs
are the same as the true spiked concentration for about half the labs. However, for about three to six labs
per media, t-tests indicate that there is reasonable to good confidence the reported measured
concentrations are the same as the true spiked concentration. However, it was not consistent across media
as to which labs had reported measured concentrations that were or were not the same as the true spiked
concentration. Labs 4 and 16 though had results with good confidence of being equal to the true values
for all four media.
The results of the high spike samples are given in Table A-91. Of the 160 high spike samples, 40, 37, 39,
and 39 samples have acceptable recovery in the groundwater, reagent water, surface water, and
wastewater, respectively. The median recovery was acceptable for all labs and all media. With a spike
level of 200.0 ng/1, the lowest modified concentration across the media was 128.2 ng/1, and the highest
modified concentration across the media was 326.7 ng/1. All labs had acceptable RSD in all media. While
the data from individual labs tended to be normally distributed, the data when combined across all labs
were not normally distributed except for surface water and wastewater. Overall for all media, t-tests
indicate that confidence is low the measured concentrations reported by the individual labs are the same
as the true spiked concentration for about half the labs. However, for about three to four labs per media, t-
tests indicate that there is reasonable to good confidence the reported measured concentrations are the
same as the true spiked concentration. However, it was not consistent across media as to which labs had

2.6 Perfluorononanoic acid (PFNA)
The measurements and recoveries combined for all labs are presented in Figures B-l 1 and 12. Overall, the

acceptable limits and are nicely small.
Results of the blank samples are given in Table A-6. At least one lab reported a concentration for each
media for PFNA in the blank samples. Lab 11 reported a concentration in at least one sample of all media.
The highest reported concentration across the media was 29.5 ng/1.
The results of the low spike samples are given in Table A-49. Of the 159 low spike samples (only 39
wastewater), 38, 40, 38, and 38 samples have acceptable recovery in the groundwater, reagent water,
surface water, and wastewater, respectively. The median recovery was acceptable for all labs and all
media. With a spike level of 60.0 ng/1, the lowest modified concentration across the media was 38.8 ng/1,
and the highest modified concentration across the media was 86.1 ng/1. All labs had acceptable RSD in all
media. While the data from individual labs tended to be normally distributed, the data when combined
across all labs were not normally distributed except for reagent water and surface water. Overall for all
media, t-tests indicate that confidence is low the measured concentrations reported by the individual labs
are the same as the true spiked concentration for about half the labs. However, for about four to six labs
per media, t-tests indicate that there is reasonable to good confidence the reported measured
concentrations are the same as the true spiked concentration. However, it was not consistent across media
as to which labs had reported measured concentrations that were or were not the same as the true spiked

and the highest modified concentration across the media was 86.1 ng/1. All labs had acceptable RSD in all
media. The data from individual labs tended to be normally distributed, and the data when combined
across all labs were also normally distributed. Overall for all media, t-tests indicate that confidence is
good the measured concentrations reported by the individual labs are the same as the true spiked
concentration for about half the labs. For about four to six labs per media, t-tests indicate that there is very
good confidence the reported measured concentrations are the same as the true spiked concentration.
However, it was not consistent across media as to which labs had reported measured concentrations that
were or were not the same as the true spiked concentration. Lab 2 though had results with good
confidence of being equal to the true values for all four media.

With a spike level of 60.0 ng/1, the lowest modified concentration across the media was 41.4 ng/1, and the
highest modified concentration across the media was 101.2 ng/1. All labs had acceptable RSD for all
media. While the data from individual labs tended to be normally distributed, the data when combined

data from individual labs tended to be normally distributed, and the data when combined across all labs
were also normally distributed except in wastewater. Overall for all media, t-tests indicate that confidence
is low the measured concentrations reported by the individual labs are the same as the true spiked
concentration for about half the labs. However, for about three to five labs per media, t-tests indicate that
there is good confidence the reported measured concentrations are the same as the true spiked

2.10 Perfluoropentanoic acid (PFPeA)
The measurements and recoveries combined for all labs are presented in Figures B-19-21. Overall, the
results are good, but a few high outliers, mainly with the low-spiked groundwater, exist that skew the

lab 4 (too low). With a spike level of 54.72 ng/1, the lowest modified concentration across the media was
25.1 ng/1, and the highest modified concentration across the media was 75.0 ng/1. All labs had acceptable
RSD for all media. The data from individual labs tended to be normally distributed as were the data when
combined across all labs. Overall for all media, t-tests indicate that confidence is low the measured
concentrations reported by the individual labs are the same as the true spiked concentration for about half
the labs. However, for about two to five labs per media, t-tests indicate that there is good confidence the
reported measured concentrations are the same as the true spiked concentration. However, it was not
consistent across media as to which labs had reported measured concentrations that were or were not the
same as the true spiked concentration.

were not normally distributed except for groundwater and surface water. Overall for all media, t-tests
indicate that confidence is low the measured concentrations reported by the individual labs are the same
as the true spiked concentration for about half the labs. However, for about three to six labs per media, t-
tests indicate that there is good confidence the reported measured concentrations are the same as the true
spiked concentration. However, it was not consistent across media as to which labs had reported

Results of the blank samples are given in Table A-17. None of the labs reported a concentration for
PFPeS in any of the blank samples.

2.20 Fluorotelomer sulfonic acid 8:2 (FtS 8:2)
The measurements and recoveries combined for all labs are presented in Figures B-41 and 42. Overall, the

interquartile range of all recoveries are within the acceptable limits, except high-spiked wastewater whose
upper quartile is just over 130%.
Results of the blank samples are given in Table A-20. None of the labs reported a concentration for

2.2] Fluorotelomer sulfonic acid 6:2 (FtS 6:2)
The measurements and recoveries combined for all labs are presented in Figures B-43-45. Overall, the
results are fair, but a large number of high outliers exist that skew the results. Also, extreme
-------
21
measurements both high and low skew the results but don't qualify as outliers. In particular, high-spiked
groundwater and low-spiked surface water each have a sampled with an adjusted measured concentration
over 1000 ng/1. Also, due to background adjustment, several samples have adjusted measured
concentrations that are negative. The interquartile range of recoveries for high-spiked reagent water and
high-spiked wastewater are the only spike-media combinations within the acceptable limits for recovery.
The rest extend below 70%. The low-spiked surface water mean is higher than the interquartile range due
to the outliers.
Results of the blank samples are given in Table A-21. At least one lab reported a concentration for each
media for FtS 6:2 in the blank samples. Lab 10 reported a concentration in at least one sample of all

16 had unacceptable RSD in reagent water. Lab 11 had unacceptable RSD in surface water. The RSD
across all labs was unacceptable for surface water. While the data from individual labs tended to be
normally distributed, the data when combined across all labs was not normally distributed except for
wastewater. Overall for all media, t-tests indicate that confidence is low the measured concentrations
reported by the individual labs are the same as the true spiked concentration for about half the labs.

was 65.6 ng/1, and the highest modified concentration across the media was 1089.0 ng/1. Lab 10 had
unacceptable RSD for groundwater. Lab 11 had unacceptable RSD for reagent water. The across all labs
RSD for groundwater was unacceptable. While the data from individual labs tended to be normally

wastewater, respectively. The median recovery was acceptable for all labs and all media. With a spike
level of 160 ng/1, the lowest concentration across the media was 92.7 ng/1, and the highest concentration
across the media was 308.7 ng/1. All labs had acceptable RSD for all media. While the data from
individual labs tended to be normally distributed, the data when combined across all labs was not
normally distributed. Overall for all media, t-tests indicate that confidence is low the measured
concentrations reported by the individual labs are the same as the true spiked concentration for about half
the labs. However, for about one to six labs per media, t-tests indicate that there is good confidence the
reported measured concentrations are the same as the true spiked concentration. However, it was not

The measurements and recoveries combined for all labs are presented in Figures B-54 and 55. Overall, the

range of all recoveries are within the acceptable limits and are nicely small. While all samples should
have had the same concentration of the surrogate MPFDoA added, for consistency with the analytes, the

normally distributed except for reagent water. Overall for all media, t-tests indicate that confidence is low
the measured concentrations reported by the individual labs are the same as the true spiked concentration
for less than half the labs. However, for about five to seven labs per media, t-tests indicate that there is
good confidence the reported measured concentrations are the same as the true spiked concentration.
However, it was not consistent across media as to which labs had reported measured concentrations that
were or were not the same as the true spiked concentration. Labs 4, 12, and 16 though had results with
good confidence of being equal to the true values for all four media.
2.41 ]H, JH, 2H, 2H-petjluoro-l[1,2-LX 'j/hexvl sulfonic acid (M242FTS)
The measurements and recoveries combined for all labs are presented in Figures B-86 and 87. Overall, the
results are good, but numerous high outliers and outliers exist that skew the results. The interquartile
range of all recoveries are within the acceptable limits. While all samples should have had the same
concentration of the surrogate M242FTS added, for consistency with the analytes, the results from the
-------
42
blank, low spike, and high spike samples will be discussed separately. This also allows a pattern to be
seen in case the concentration of the analytes affects the reading of the surrogates.
Results of the blank samples are given in Table A-41. Of the 200 blank samples, 37, 37, 35, and 39
samples have acceptable recovery in the groundwater, reagent water, surface water, and wastewater,
respectively. The median recovery for reagent water was unacceptable for lab 4 (too low). With a spike
level of 149.6 ng/1, the lowest concentration across the media was 83.8 ng/1, and the highest concentration
across the media was 320.0 ng/1. All labs had acceptable RSD for all media. While the data from
individual labs tended to be normally distributed, the data when combined across all labs was not
normally distributed except for wastewater. Overall for all media, t-tests indicate that confidence is low
the measured concentrations reported by the individual labs are the same as the true spiked concentration
for more than half the labs. However, for about two to four labs per media, t-tests indicate that there is
good confidence the reported measured concentrations are the same as the true spiked concentration.
However, it was not consistent across media as to which labs had reported measured concentrations that
were or were not the same as the true spiked concentration. Lab 16 though had results with good
confidence of being equal to the true values for all four media.
The results of the low spike samples are given in Table A-84. Of the 159 low spike samples (only 39
wastewater), 37, 38, 39, and 35 samples have acceptable recovery in the groundwater, reagent water,
surface water, and wastewater, respectively. The median recovery was acceptable for all labs and all
media. With a spike level of 149.6 ng/1, the lowest concentration across the media was 0.0 ng/1, and the
highest concentration across the media was 288.2 ng/1. Lab 4 had unacceptable RSD for groundwater.
While the data from individual labs tended to be normally distributed, the data when combined across all

it was not consistent across media as to which labs had reported measured concentrations that were or
were not the same as the true spiked concentration. Lab 4 though had results with good confidence of
being equal to the true values for all four media.
The results of the high spike samples are given in Table A-127. Of the 160 high spike samples, 36, 37, 35,
and 34 samples have acceptable recovery in the groundwater, reagent water, surface water, and
wastewater, respectively. The median recovery was acceptable for all labs and all media. With a spike
level of 149.6 ng/1, the lowest concentration across the media was 46.1 ng/1, and the highest concentration
across the media was 285.2 ng/1. Lab 4 had unacceptable RSD for groundwater and surface water. While
the data from individual labs tended to be normally distributed, the data when combined across all labs
was not normally distributed. Overall for all media, t-tests indicate that confidence is low the measured
concentrations reported by the individual labs are the same as the true spiked concentration for about half
the labs. However, for about four to six labs per media, t-tests indicate that there is good confidence the
reported measured concentrations are the same as the true spiked concentration. However, it was not
consistent across media as to which labs had reported measured concentrations that were or were not the
same as the true spiked concentration. Labs 4 and 16 though had results with good confidence of being
equal to the true values for all four media.

The measurements and recoveries combined for all labs are presented in Figures B-88 and 89. Overall, the
results are good, but numerous high outliers and outliers exist that skew the results. The interquartile
range of all recoveries are within the acceptable limits. While all samples should have had the same
concentration of the surrogate d5NEtFOSAA added, for consistency with the analytes, the results from
the blank, low spike, and high spike samples will be discussed separately. This also allows a pattern to be
seen in case the concentration of the analytes affects the reading of the surrogates.
Results of the blank samples are given in Table A-41. Of the 200 blank samples, 37, 34, 33, and 34
samples have acceptable recovery in the groundwater, reagent water, surface water, and wastewater,
respectively. The median recovery for surface water was unacceptable for lab 5 (too high). The median
recovery for wastewater was unacceptable for lab 5 (too high). With a spike level of 160.0 ng/1, the lowest
concentration across the media was 90.1 ng/1, and the highest concentration across the media was 338.0
ng/1. All labs had acceptable RSD for all media. While the data from individual labs tended to be
normally distributed, the data when combined across all labs was not normally distributed except for
reagent water. Overall for all media, t-tests indicate that confidence is low the measured concentrations
reported by the individual labs are the same as the true spiked concentration for about half the labs.
However, for about four to five labs per media, t-tests indicate that there is good confidence the reported
measured concentrations are the same as the true spiked concentration. However, it was not consistent

3 SUMMARY INTEMLAROMATOMY RESULTS
3.1 Media
The statistics on data sets with acceptable RSD, acceptable recovery, and acceptable t-tests were
combined across analytes, spike levels, and labs to examine if the media affected the results. The results
are presented in Table C-l with the analyte and surrogate results presented separately and combined
(labeled total). The recoveries for each analyte and surrogate were also graphed separately by media in
Figures C-l-8. [Note: For all figures where all analytes or surrogates where graphed together, the analytes
and surrogates are labeled with a number in front of their acronym. This was done to force the analytes
and surrogates to graph in a specific order, mainly grouped by functional group in order of descending
number of carbons.] The figures are standardized with a low recovery of 0% and a high recovery of
250%. Only a small number of outliers lie outside this range and are not visible in these graphs. The
media had no discernable effect on the results.
3.2 Spike Level
The statistics on data sets with acceptable RSD, acceptable recovery, and acceptable t-tests were
combined across analytes, media, and labs to examine if the spike level affected the results. The results
are presented in Table C-2 with the analyte and surrogate results presented separately and combined
(labeled total). The recoveries for each analyte and surrogate were also graphed separately by spike level
in Figures C-9-13. The figures are standardized with a low recovery of 0% and a high recovery of 250%.
Only a small number of outliers lie outside this range and are not visible in these graphs. The recovery of
the surrogates does not change significantly between spike levels of the analytes. There is a slightly
smaller percentage of acceptable recoveries with the low-spiked analytes versus the high-spiked analytes.
Conversely, there is a lower percentage of analyte sets passing the t-test with the high-spiked samples
versus the low-spiked samples, but the reverse is true for the surrogates. The analyte figures indicate that
the low-spiked samples have a larger number of outliers than the high-spiked samples. The interquartile
ranges appear to be slightly smaller with the low-spiked samples than the high-spiked samples. The
surrogate figures indicate that the blank, low-spike, and high-spiked samples for the surrogates are very
similar.
3.3 Analytes and Surrogates
The statistics on data sets with acceptable RSD, acceptable recovery, and acceptable t-tests were
combined across spike levels, media, and labs to examine if the analyte or surrogate affected the results.
The results are presented in Table C-3 for the analytes and in Table C-4 for the surrogate. The recoveries
for each analyte and surrogate were also graphed separately in Figures C-14 and 15, respectively. The
figures are standardized with a low recovery of 0% and a high recovery of 250%. Only a small number of
outliers lie outside this range and are not visible in these graphs. The analytes and surrogates are graphed
in descending order of carbon chain length within functional groups.
For the analytes, within the carboxylic acids, the recoveries start to decrease almost linearly above a
carbon length of ten and below a carbon length of seven, although the decrease is less notable on the
lower end. A similar decrease is observed with the sulfonic acids above a carbon length of seven, but the
effect is less noticeable, and the effect is not clear on the lower carbon chain length. PFOSA has similar
-------
47
recovery to the equivalent length carboxylic acid. The fluorotelomer sulfonic acids do not have a chain
length effect with recovery, but FtS 6:2 has a clear decrease in recovery versus FtS 8:2 and FtS 4:2. With
only two sulfonamidoacetic acids, no chain length effect can be discerned, but NEtFOSAA has a
noticeably lower recovery than NMeFOSAA. All analytes have similar, very good RSDs, with the
exception of FtS 6:2, which while still had a good RSD, was noticeably decreased from all other analyte
RSDs. The t-tests mirror the recovery results in terms of carbon chain length effect and decrease in
passing the test with longer and shorter chain lengths. Figure C-14 also shows the chain length effect with
outliers increasing on either end of the chain length. Not shown of Figure C-14 with its maximum
recovery of 250% are two PFOS and two FtS 6:2 outliers outside this range. FtS 6:2 is the only analyte
whose overall interquartile range was not within acceptable limits. The sulfonamidoacetic acids appear to
have the most outliers, and the fluorotelomer sulfonic acids appear to have more variance in general than
other functional groups.
For the surrogates, there does not appear to be a clear chain length recovery effect like the analytes.
However the longest and the shortest carboxylic acid do a slightly decreased recovery compared to the
rest of the carboxylic acids. The sulfonamidoacetic acids have slightly decreased recoveries also. All
surrogates have similar, very good RSDs, with the possible exception of FtS 4:2, which while still had a
good RSD, was noticeably decreased from all other surrogate RSDs. The t-tests show a decrease in
passing rates with higher chain lengths of shorter chain lengths similar to the analytes, but with the
carboxylic acids, the pattern is not clear. Figure C-15 shows a similar chain length effect as analytes with
outliers increasing on either end of the chain length. Not shown of Figure C-15 with its maximum
recovery of 250% is one MFtS 6:2 outlier outside this range. Similar to the analytes, the
sulfonamidoacetic acids appear to have the most outliers, and the fluorotelomer sulfonic acids appear to
have more variance in general than other functional groups.

APPENDIX E JUSTIFICATION FOR EXCLUSION OF
LABORATORIES FOR VALIDATION OF METHOD 8327
-------
E-l
Internal and external laboratories that submitted data for the validation of Method 8327 were sent a
survey so that a consistent rationale for inclusion vs. exclusion of data could be determined. TechLaw
was tasked with validating the data according to the method, QAPP, and study instructions. Both were
used in developing the rationale for exclusion.
The following laboratories were excluded with the rationale provided:
Laboratory 1:
Method Deviation: Target compounds stock and surrogate spiking solutions were prepared at
concentrations of 20 ng/mL in 1:1 methanol-water containing 0.1% acetic acid using borosilicate glass
vials and rubber lined plastic caps. The method states that these are to be prepared in 95:5 ACN-water (to
keep longer chain PFAS in solutions at higher concentrations). Use of borosilicate glass and rubber septa
is not recommended.
QC Issues: TechLaw validation report states "The data provided by the laboratory contains numerous
quality control defects as well as elevated reporting limits." Initial calibrations did not meet the minimum
criteria for curve fit (R2), minimum number of points, and/or refit criteria for many of the compounds, and
multiple CCV failures were observed. [After the validation reports were completed, SW-846 PFAS
workgroup opined that analysis should have halted until minimum criteria were met]. Also, 47% of
surrogates failed to meet preliminary recovery limits of 70-130% used as a benchmark for acceptable
laboratory performance and comparability of data in study samples (all other labs whose data was
included in the statistical analysis had a failure rate of 7% or less). Four or more surrogates did not meet
the recovery limits in 100% of study samples (compared with a maximum of 5% of study samples from
other labs whose data was included in the statistical analysis). Results for most target analytes were
qualified during validation due to calibration and/or surrogate QC failures. Given the laboratory QC
issues observed in this data set, Laboratory l's study sample data cannot be directly compared to or
pooled with data from other labs.
Laboratory 3:
Method Deviations: At the time of the study, the method developer reported that in the developer's
opinion the laboratory was deviating from the method. However, deviations could not be confirmed
during the survey.
QC Issues: Lab 3 stated in survey "The responses of some compounds in standard solutions and in
fortified samples were erratic during analyses on our instrument. The causes have not yet been
determined." Initial calibration for one analysis batch did not meet the minimum criteria for curve fit (R2)
and/or refit criteria for many of the compounds, and multiple CCV failures were observed. [After the
validation reports were completed, SW-846 PFAS workgroup opined that analysis should have halted
until minimum criteria were met]. Also, 19% of surrogates failed to meet preliminary recovery limits of
70-130% used as a benchmark for acceptable laboratory performance and comparability of data in study
samples (compared to a maximum of 7% of surrogates in study samples from other labs whose data was
included in the statistical analysis). Four or more surrogates did not meet the recovery limits in 37% of
study samples (compared with a maximum of 5% of study samples from other labs whose data was
included in the statistical analysis). Results for most target analytes were qualified during validation due
to calibration and/or surrogate QC failures. Given the laboratory QC issues observed in this data set,
Laboratory 3's study sample data cannot be directly compared to or pooled with data from other labs.

E-2
Laboratory 13:
Method Deviation: Target compounds stock and surrogate spiking solutions were prepared at
concentrations of 20 ng/mL in 1:1 methanol -water containing 0.1% acetic acid. The method state s that
these are to be prepared in 95:5 ACN-water (to keep longer chain PFAS in solutions at higher
concentrations).
Note: The laboratory reprocessed these samples with calibration standards prepared from stock standards
in methanol and significantly improved recoveries and precision were observed. However, samples were
analyzed over a period of a couple of days prior to the associated initial calibration standards, which was
a significant deviation from the study instructions. Therefore, study sample data from Laboratory 13 were
not included with data from the other laboratories in the statistics summary or in this data validation
summary.
Laboratory 15:
Method deviation: A subsample was removed from the original container prior to preparation (0.5 ml
prepared instead of whole 5 ml). Low to no recoveries were observed for mid to longer chain PFAS in all
study samples.
Note: The laboratory prepared the remaining 4.5 ml of sample following the correct method protocol and
mid and longer chain PFAS were recovered at expected concentrations. Data could not be included due to
the high bias associated with mid and longer chain PFAS.
