(iii) Field -Generated Quality Control (QC) Blanks — Blanks associated with field activities as defined in FQ 1210 of the DEP SOPs shall be collected according to the requirements of FQ 1230. (1) If an analyte detected in the sample is also found in any field -generated QC blank that is associated with the sample the CONTRACTOR shall investigate and attempt to determine the cause of the QC blank contamination. The outcome of this investigation shall be reported and shall include a discussion of the corrective measures taken to minimize future occurrences of QC blank contamination. (2) If an analyte detected in the sample is also found in any field -generated QC blank that is associated with the sample the CONTRACTOR shall ensure that the analyte in the affected sample is reported as estimated ("J" with a narrative explanation) unless the analyte concentration in the affected sample is at least 10 times the reported QC blank value concentration (iv) The CONTRACTOR shall identify a second laboratory that meets the requirements in Section 1 and shall arrange to have split samples collected using the sampling procedures specified in the Contract and analyzed by the primary and secondary laboratories. Split samples shall be collected at least once during the project and at least annually thereafter The CONTRACTOR shall specify the procedure for splitting the samples in the planning document. (1) The results from the two laboratories shall be assessed using a precision criterion of no greater than 20% RPD as an initial guide to assessment of the split sample results. (2) All differences between split sample results from the two laboratories shall be investigated and resolved. 4. REPORTING, DOCUMENTATION AND RECORDS RETENTION a. The CONTRACTOR shall ensure that all laboratory and field records as outlined in Rules 62-160.240 and .340, F.A.0 are retained for a minimum of five years after the project completion. b. All field and laboratory records that are associated with work performed under this Contract shall be organized so that any information can be quickly and easily retrieved for inspection, copying or distribution. c. The CONTRACTOR shall ensure that all laboratory reports are issued in accordance with NELAC requirements. These reports shall be submitted to the DEP contract manager and shall include the following information: ► Laboratory sample identification (ID) and associated Field ID ► Analytical/test method ► Parameter/analyte name ► Analytical result (including dilution factor) ► Result unit ► Applicable DEP Qualifiers per Table 1 of Chapter 62-160, F.A.C. ► Result comment(s) to include corrective/preventive actions taken for any failed QC measure (e.g., QC sample, calibration failure, etc.) or other problem related to the analysis of the samples ► Date and time of sample preparation (if applicable) ► Date and time of sample analysis ► Results of laboratory verification of field preservation ► Sample matrix ► DoH ELCP certification number for each laboratory (must be associated with the test result(s) generated by the laboratory) ► MDL DEP Agreement No. LP/4##, Attachment H, Page 3 of 12
