The residual canister receipt vacuums 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

N

TO-15 SIM (2306432-10BLB): Tetrachloroethene and 1,1,2,2-tetrachloroethane were detected in the method blank at levels
between the method detection limit (MDL) and reporting limit (RL). The tetrachloroethene result in EPD-WA-06-061823 was
greater than ten times the blank value; therefore, no qualification was applied. The tetrachloroethene results in all other samples
were qualified as nondetect (flagged U) at the RL.

The 1,1,2,2-tetrachloroethane result in EPD-DW-D-061823 was qualified as nondetect (flagged U) at the RL. The 1,1,2,2-
tetrachloroethane results in all other samples were nondetect; therefore, no further qualifications were applied.

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.

The residual canister receipt vacuums 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.

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.

Criteria

Exceedance/Notes

N

The residual canister receipt vacuums 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-DW-G-062123 listed on the laboratory work order summary was 11.0"Hg (a.k.a.
-11.0"Hg). This large 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-DW-G-062123 should be used with caution.

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.

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.
