Receipt The samples were received on 3/17/2023 11:50 AM. Unless otherwise noted below, the samples arrived in good condition, and, where required, properly preserved and on ice. The temperature of the cooler at receipt time was 1.7°C

GC/MS VOA

Method 8260D: Due to the TCLP extraction process, the following sample was diluted X5: FULL TCLP (670-16475-1).

No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

GC/MS Semi VOA Method 8270E: Internal standard (ISTD) response for Perylene-d12 for the following sample in analytical batch 400-618363 was outside acceptance criteria: (LB 400-617947/1-E). This ISTD does not correspond to any of the requested target compounds reported from this analytical batch; therefore, the data have been reported.

Method 8270E: Six surrogates are used for this analysis. The laboratory's SOP allows one of these surrogates to be outside acceptance criteria without performing re-extraction/re-analysis. The following sample contained an allowable number of surrogate compounds outside limits: FULL TCLP (670-16475-1). These results have been reported and qualified.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Herbicides No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Pesticides Method 8081B: Two surrogates are used for this analysis. The laboratory's SOP allows one of these surrogates to be outside acceptance criteria without performing re-extraction/re-analysis. The following sample contained an allowable number of surrogate compounds outside limits: FULL TCLP (670-16475-1). These results have been reported and qualified.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Metals No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Receipt The samples were received on 3/17/2023 11:50 AM. Unless otherwise noted below, the samples arrived in good condition, and, where required, properly preserved and on ice. The temperature of the cooler at receipt time was 1.7°C

GC/MS VOA

Method 8260D: Due to the TCLP extraction process, the following sample was diluted X5: FULL TCLP (670-16477-1).

No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

GC/MS Semi VOA Method 8270E: Internal standard (ISTD) response for Perylene-d12 for the following sample in analytical batch 400-618363 was outside acceptance criteria: (LB 400-617947/1-E). This ISTD does not correspond to any of the requested target compounds reported from this analytical batch; therefore, the data have been reported.

Method 8270E: Six surrogates are used for this analysis. The laboratory's SOP allows one of these surrogates to be outside acceptance criteria without performing re-extraction/re-analysis. The following sample contained an allowable number of surrogate compounds outside limits: FULL TCLP (670-16477-1). These results have been reported and qualified.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Herbicides No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Pesticides No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Metals No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
