Subject: CPT Site Investigation Green River Golf Course Corona, California GREGG Project Number: 09-0310SH

Dear Mr. Kulikowski:

The following report presents the results of GREGG Drilling & Testing’s Cone Penetration Test investigation for the above referenced site. The following testing services were performed:

1 Cone Penetration Tests (CPTU) 2 Pore Pressure Dissipation Tests (PPD)

3 Seismic Cone Penetration Tests (SCPTU) 4 Resistivity Cone Penetration Tests (RCPTU) 5 UVOST Laser Induced Fluorescence (UVOST)

6 Groundwater Sampling (GWS) 7 Soil Sampling (SS) 8 Vapor Sampling (VS)

9 Vane Shear Testing (VST) 10 SPT Energy Calibration (SPTE)

A list of reference papers providing additional background on the specific tests conducted is provided in the bibliography following the text of the report. If you would like a copy of any of these publications or should you have any questions or comments regarding the contents of this report, please do not hesitate to contact our office at (562) 427-6899.

Sincerely, GREGG Drilling & Testing, Inc.
