CASE NARRATIVE
Laboratory number: 292701
Client: SLR International
Project: 102.01422.00001
Location: Jean Sweeney
Request Date: 09/21/17
Samples Received: 09/21/17
This data package contains sample and QC results for seven soil samples, requested for the above referenced project on 09/21/17. The samples were received cold and intact.

TPH-Extractables by GC (EPA 8015B):

JS-SW-B107 (lab # 292701-005), JS-BS-A109 (lab # 292701-006), and JS-BS-B109 (lab # 292701-009) were diluted due to the dark and viscous nature of the sample extracts. No other analytical problems were encountered.

Metals (EPA 6010B):

No analytical problems were encountered.

CASE NARRATIVE
Laboratory number: 292734
Client: SLR International
Project: 102.01422.00001
Location: Jean Sweeny
Request Date: 09/22/17
Samples Received: 09/22/17
This data package contains sample and QC results for eight soil samples, requested for the above referenced project on 09/22/17. The samples were received cold and intact.

TPH-Extractables by GC (EPA 8015B):

Matrix spikes QC902184,QC902185 (batch 251980) were not reported because the parent sample required a dilution that would have diluted out the spikes.

JS-SW-C01 (lab # 292734-003) was diluted due to the dark and viscous nature of the sample extract. No other analytical problems were encountered.

CASE NARRATIVE
Laboratory number: 292760
Client: SLR International
Project: 102.01422.00001
Location: Jean Sweeney
Request Date: 09/22/17
Samples Received: 09/15/17
This data package contains sample and QC results for six soil samples, requested for the above referenced project on 09/22/17. The samples were received cold and intact. This report was revised and reissued on 10/10/17 to include revised client sample IDs.

TPH-Extractables by GC (EPA 8015B):

Matrix spikes QC902184,QC902185 (batch 251980) were not reported because the parent sample required a dilution that would have diluted out the spikes. No other analytical problems were encountered.
