SAMPLE DELIVERY GROUP CASE NARRATIVE

Volatiles by GCMS By Method SW846 8260CMatrix SO Batch ID: VY3521

All samples were analyzed within the recommended method holding time.

All method blanks for this batch meet method specific criteria.

Sample(s) TC42188-1MS, TC42188-1MSD were used as the QC samples indicated.

Matrix Spike Duplicate Recovery(s) for Methyl bromide are outside control limits. Probable cause due to matrix interference.

TC42161-1, TC42161-2, TC42161-3, TC42161-4 for Hexachlorobutadiene, Dichlorodifluoromethane: CCV recovery was above method acceptance criteria. This target analyte was not detected in the sample.

Extractables by GCMS By Method SW846 8270DMatrix SO Batch ID: OP31117

All samples were extracted within the recommended method holding time.

All samples were analyzed within the recommended method holding time.

Sample(s) TC42188-1MS, TC42188-1MSD were used as the QC samples indicated.

All method blanks for this batch meet method specific criteria.

Matrix Spike Recovery(s) for 2,4-Dinitrophenol, 4,6-Dinitro-o-cresol, Pentachlorophenol are outside control limits. Probable cause due to matrix interference.

Matrix Spike Duplicate Recovery(s) for 2,4-Dinitrophenol, 4,6-Dinitro-o-cresol, Pentachlorophenol are outside control limits. Probable cause due to matrix interference.

Metals By Method SW846 6010BMatrix SO Batch ID: MP22463

All samples were digested within the recommended method holding time.

All samples were analyzed within the recommended method holding time.

All method blanks for this batch meet method specific criteria.

Sample(s) TC42161-1MS, TC42161-1MSD, TC42161-1SDL were used as the QC samples for metals.

Matrix Spike Duplicate Recovery(s) for Lead are outside control limits. Probable cause due to matrix interference.

Matrix Spike/Matrix Spike Duplicate Recovery(s) for Barium are outside control limits. Spike amount low relative to the sample amount. Refer to lab control or spike blank for recovery information.

RPD(s) for Serial Dilution for Arsenic, Barium, Chromium are outside control limits for sample MP22463-SD1. Serial dilution indicates possible matrix interference.

TC42161-1 for Selenium: Elevated reporting limit due to dilution required for matrix interference.

TC42161-3 for Cadmium, Selenium: Elevated reporting limit due to dilution required for high interfering element.
