OHM RemediationServices Corp. SAMPLING AND ANALYSIS PLANTB = Trip BlankFtB= Equipment Rinsate BlankDP = Field Duplicate/ReplicateAdditional information may be required in the sample identification (ID) column. This willinclude operable unit, site designation, truck or pile number, and any grid coordinates orlocation designations associated with the sample.3.3 Sample Preservation and Holding TimesWhen samples are collected for off-site analyses, they will be sent to the laboratory within 24hours after collection to ensure that the most reliable and accurate answers will be obtained as aresult of the analysis. The holding time begins from the date of collection in the field.All environmental samples, as well as QA/QC samples, will be preserved to a temperature of4°C prior to shipment to the analytical laboratory, using ice or refrigeration. This temperatureshould be maintained during shipment by placing ice in leak-proof containers, and placing itabove and below the sample containers. Other sample preservation requirements and holdingtimes applicable to the sample matrix and analyses are listed in Appendix A, Table A-l.3.4 Field QC SamplesThe appropriate number of field QC samples, as specified in the NEESA 20.2-047B documentwill be collected during this project. These samples will include field blanks, equipmentrinsate blanks and field duplicate samples. These samples will be collected at the followingfrequencies and analyzed for the parameters listed in Appendix A, Table A- 1:lField Blanks - Field blanks consist of the source water used in decontamination andsteam cleaning. At a minimum, one field blank from each sampling event and eachsource of water will be collected and analyzed for the same parameters and at the sameQC levels as the related samples.lEquipment Rinsate Blank - Equipment rinsate blanks are the final analyte-free waterrinse from equipment cleaning collected daily during a sampling event. One equipmentrinsate blank will be collected daily for NFESC Level C and E reporting. However,only samples from every other day are analyzed. The laboratory will be informed as towhich rinsate blanks will be analyzed, The remaining rinsate blanks are to be held bythe laboratory and analyzed only if evidence of contamination exists.lField Duplicate - Duplicates for soil samples are collected, homogenized, and split. Ailsamples except volatiles are homogenized and split. Volatiles are not mixed, but selectOHM Project 16487SAP Sampling and Analysis Plan h4ay 199sInformation herein is proprietary and confidential and to be used or rekascd to others only with explicit written permission of OHM Rancdiationscniccs Corp.3-8
