CASE NARRATIVE

This data summary package is comprised of sediment and soil samples received for analysis on December 18, 2008 (Assigned Sample Delivery Group: 08120163). The samples are from Project Name: Plainwell Dam #2 Investigation. The samples were collected by Camp, Dresser & McKee (CDM) on December 10, 2008. Samples were delivered to Northeast Analytical, Inc. (NEA) by FedEx courier service. All samples were received at the laboratory intact and within holding times.

This sample delivery group consists of the following samples:

NEA Sample ID: AL20776 AL20777 AL20778 AL20779 AL20780 AL20781 AL20782 AL20783 AL20784 AL20785 AL20786 AL20787 AL20788 AL20789 AL20790 AL20791 AL20792 AL20793 AL20794 AL20795

PCB Aroclor Analysis

Analysis for PCB Aroclors was performed by EPA Method 8082 single column GC analysis. The Accelerated Solvent Extraction Method (EPA Method 3545) was employed for the sediment and soil samples. The following technical and administrative items were noted for the analysis:

1. The concentration results for Aroclor 1242 was flagged to denote that an altered Aroclor pattern was observed for several samples. Please see Form 1 for details.

2. The concentration results for Aroclor 1254 was flagged to denote that an altered Aroclor pattern was observed for several samples. Please see Form 1 for details.

3. The percent recovery for the TCMX and DCBP surrogates was diluted out for the Matrix Spike and the Matrix Spike Duplicate (NEA ID: AL20785M and AL20785K)' samples due to high PCB concentration in the samples. Please see Form 2 for details.

4. The percent recovery for the TCMX and DCBP surrogates was diluted out for several samples (NEA ID: AL20783, AL20784, AL20791 and AL20793-95) due to the high PCB concentration in the samples. Please see Form 2 for details.

Northeast Analytical, Inc. 08120163.PDF Page 5

5. Sample P2SD-4A-01 (NEA ID: AL20781) had a DCBP surrogate recovery below QC limits, but the alternate TCMX surrogate was within limits. Please see form 2 for details.

Form -1 Qualifier Summacy PCB Analysis:

J-Denotes concentration result greater than the MDL but less than the PQL B-Denotes analyte observed in associated method blank at a concentration exceeding the PQL U-Denotes analyte not observed at a concentration greater than the PQL
