1 February 26, 07 KSA Environmental Laboratory Inc. Hydrologic Associates - Miami Attn: Brad Waller 8925 S.W. 148th Street Suite 212 Miami, FL RE: Parkland KSA Workorder: Q0012 Dear Brad Waller, Enclosed is a copy of your laboratory report for test samples received by our laboratory on 02/16/07 13:55. Unless otherwise noted in an attached project narrative, all samples were received in acceptable condition and processed in accordance with the referenced methods/procedures. s for these procedures apply only to the samples as submitted. This data has been produced in accordance with NELAC standards. This report shall not be reproduced except in full, without the written approval of the Laboratory. If you have any questions or require further information, please do not hesitate to contact me. Sincerely, Emerson Perez Project Manager Enclosure(s) Page 1 of 23 KSA Environmental Laboratory Inc USA Today Way - Miramar, FL (954)

2 CASE NARRATIVE KSA Work Order #: Q0012 Project Name: Parkland I. Sample Receiving Notes All samples listed on the Chain of Custody identified with KSA Work Order # Q0012 were received with containers intact, correctly preserved, and at the proper temperature for the requested analyses. II. Data Notes The analyses were performed in accordance with KSA Environmental Laboratory SOP's and industry-standard methodologies in compliance with FDEP/NELAC criteria. There were no notable problems encountered in the analytical process. III. Quality Control Notes EPA 8081: The LCS/LCSD for batch exceeded laboratory guidelines for delta-bhc, Endosulfan sulfate, and Endrin aldehyde; however, the LCS and LCSD percent recoveries were within control limits. The associated samples are flagged with the FDEP "J" qualifier. EPA 8260: The LCS/LCSD for batch exceeded laboratory guidelines for 1,1,1-Trichloroethane; however, the LCS and LCSD percent recoveries were within control limits. The associated samples are flagged with the FDEP "J" qualifier. EPA 300.0: The LCS/LCSD recovered slightly above the control limits for Nitrite; however, since this analyte was detected below in the samples and the high recovery would yield a high bias, no further corrective action was necessary.
