Exceedance/Notes

The residual canister receipt vacuum values in the laboratory report were recorded as positive values. The laboratory was
contacted and confirmed that all values are negative, even though the minus signs are missing, and that the laboratory uses the
following convention for recording Summa canister vacuums and pressures: vacuums are recorded as positive values using the unit
of inches of mercury ("Hg), and positive pressures are recorded using the unit pounds per square inch (psi). No qualifications were
applied.

Method blanks:

Within
Criteria

Exceedance/Notes

TO-15 SIM (2306335-10B): 1,1,2,2-Tetrachloroethane, 1,2-dibromomethane, 1,4-dichlorobenzene, chloromethane,
tetrachloroethene, and toluene were detected in the method blank at levels between the method detection limit (MDL) and
reporting limit (RL). The 1,1,2,2-Tetrachloroethane result in EPD-UW-H-061523 was qualified as nondetect (flagged U) at the RL. All
1,2-dibromomethane and 1,4-dichlorobenzene sample results were nondetect, therefore no qualifications were necessary. All
chloromethane results were qualified as nondetect (flagged U) at the RL. Tetrachloroethene results in EPD-UW-H-061523, EPD-WA-
01-061523, EPD-WA-04-061523, EPD-WA-05-061523, and EPD-WA-44-061523 were qualified as nondetect (flagged U) at the RL.
Toluene results were greater than ten times blank value in all samples, therefore no qualifications were necessary.

Overall Qualifications:

See results summary pages attached for changes to the laboratory qualifiers based upon this validation. The following is a list of qualifiers and
definitions that may be used for the validation of this data package:

The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.

J+

The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.

J-

The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.

The tentatively identified compound was manually searched for but was not found in the sample.

The analysis indicates the presence of an analyte that has been "tentatively identified" and the associated value is the approximate
concentration of the analyte in the sample.

The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.

The analyte was analyzed for but was not detected at or above the associated value (reporting limit).

The analyte was analyzed for but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.

Sample preservation, receipt, and holding times:

Within
Criteria

Exceedance/Notes

N

The canister receipt vacuum/pressure values in the laboratory report were recorded as positive values. The laboratory was
contacted and confirmed that all values are negative, even though the minus signs are missing, and that the laboratory uses the
following convention for recording Summa canister vacuums and pressures: vacuums are recorded as positive values using the unit
of inches of mercury ("Hg), and positive pressures are recorded using the unit pounds per square inch (psi). No qualifications were
applied.

The field-measured residual canister vacuum listed on the chain of custody for EPD-WA-55-061623 was -14"Hg and the receipt
laboratory-measured residual vacuum listed on the laboratory summary was -13.5"Hg. The residual vacuum value suggests that the
canister filled more slowly than intended over the allotted time and therefore the sample volume is lower than planned. The lower
volume may have affected the analytical sensitivity (possibly leading to an elevated method detection limit (MDL) and reporting
limit (RL) values). The sample may not be representative of the full collection period, therefore analytical results for EPD-WA-55-
061623 should be used with caution.

TO-15 (2306351-10A): Methylene chloride and tetrahydrofuran were detected at levels between the method detection limit (MDL)

Exceedance/Notes

CCV (2306351-11B) had low percent recovery of 1,4-dichlorobenzene. 1,4-Dichlorobenzene results in EPD-DW-B-061623, EPD-WA-
03-061623, and EPD-WA-55-061623 were qualified by the laboratory as estimated (flagged UJ) by the laboratory. No further
qualification was applied.

Overall Qualifications:

The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.

J+

The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.

J-

The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.

The tentatively identified compound was manually searched for but was not found in the sample.

The analysis indicates the presence of an analyte that has been "tentatively identified" and the associated value is the approximate
concentration of the analyte in the sample.

The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.

The analyte was analyzed for but was not detected at or above the associated value (reporting limit).

The analyte was analyzed for but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.

No rejection of results was required for this data package. The results may be used as qualified based on the findings of this validation effort.

Sample preservation, receipt, and holding times:

Within
Criteria

Exceedance/Notes

The canister receipt vacuum/pressure values in the laboratory report were recorded as positive values. The laboratory was
contacted and confirmed that all values are negative, even though the minus signs are missing, and that the laboratory uses the
following convention for recording Summa canister vacuums and pressures: vacuums are recorded as positive values using the unit
of inches of mercury ("Hg), and positive pressures are recorded using the unit pounds per square inch (psi). No qualifications were
applied.

The laboratory-measured residual vacuum for EPD-WA-03-061723 listed on the laboratory summary was -10.5"Hg. This residual
vacuum value suggests that the canister filled more slowly than intended over the allotted time and therefore the sample volume
is lower than planned. The lower volume may have affected the analytical sensitivity (possibly leading to elevated method
detection limit (MDL) and reporting limit (RL) values). The sample may not be representative of the full collection period, therefore
analytical results for EPD-WA-03-061723 should be used with caution.

Method blanks:

Within
Criteria

Exceedance/Notes

TO-15 SIM (2306430-10B): 1,4 Dichlorobenzene was detected in the method blank at a level between the method detection limit
(MDL) and reporting limit (RL). Associated sample results are nondetect, therefore no qualification was necessary.

Overall Qualifications:

The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.

J+

The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.

J-

The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.

The tentatively identified compound was manually searched for but was not found in the sample.

The analysis indicates the presence of an analyte that has been "tentatively identified" and the associated value is the approximate
concentration of the analyte in the sample.

The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.

The analyte was analyzed for but was not detected at or above the associated value (reporting limit).

The analyte was analyzed for but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.

Sample preservation, receipt, and holding times:

Within
Criteria

Exceedance/Notes

The laboratory-measured residual vacuum for EPD-WA-03-061923 listed on the laboratory summary was -10.5"Hg. This residual
vacuum value suggests that the canister filled more slowly than intended over the allotted time and therefore the sample volume
is lower than planned. The lower volume may have affected the analytical sensitivity (possibly leading to elevated method
detection limit (MDL) and reporting limit (RL) values). The sample may not be representative of the full collection period, therefore
analytical results for EPD-WA-03-061923 should be used with caution.

Method blanks:

Within
Criteria

Exceedance/Notes

TO-15 scan (2306431-10A): 1,2-Dichlorobenzene, 1,3-dichlorobenzene, and alpha-chlorotoluene were detected in the method
blank at levels between the MDL and RL. Associated sample results are nondetect, therefore no qualifications were necessary.

TO-15 SIM (2306431-10B): 1,1,2,2-Tetrachloroethane, 1,2-dichloroethane, 1,4-dichlorobenzene, m,p-xylene, naphthalene, and o-
xylene were detected in the method blank at levels between the MDL and RL. All 1,1,2,2-tetrachloroethane and 1,4-
dichlorobenzene results are non-detect, therefore no qualifications were necessary. 1,2-Dichloroethane results were qualified as
not detected (flagged U) at the RL. All m,p-xylene sample results are greater than ten times the blank value, therefore no
qualifications were applied. The naphthalene result in EPD-WA-06-061923 was qualified as estimated with possible high bias
(flagged J+). Naphthalene in EPD-WA-04-061923 was nondetect, therefore no qualification was necessary. All other naphthalene
results were qualified as not detected (flagged U) at the RL. O-xylene results in EPD-DW-E-061923, EPD-WA-02-061923, EPD-WA-
06-061923, and EPD-WA-11-061923 were qualified as estimated with possible high bias (flagged J+). O-xylene results in EPD-UW-A-
061923 and EPD-WA-04-061923 were qualified as nondetect (flagged U) at the RL. All other O-xylene results were greater than or
equal to ten times the blank value, therefore no qualifications were necessary.
