SOP: Chain of Custody, Handling, Packing, Shipping VI. Procedures Chain-of-Custody Procedures 1. Prior [o collecting samples, complete the chain-of-custody record header information by filling in the project number, project name, and the name(s) of the sampling technician(s). Please note it is important that chain- of-custody information is printed legibly using indelible ink. 2. After sample collection, enter the individual sample information by filling in the following chain-of-custody fields: 1. STA. NO. Indicates the station number or location that the sample was collected from. Appropriate values for this field include well locations, grid points, or soil boring identification numbers (e.g., MW- 3, X-20, SB-30). 2. Date. Indicates the date the sample was collected. The date format to be followed should be mm/dd/yyyy (e.g., 03/23/2005). 3. Time. Indicates the time the sample was collected. The time value should be presented using military format. For example, 3:15 P.M. should be entered as 15:15. 4. Comp. This field should be mazked with an "X" if the sample was collected as a composite. 5. Grab. This field should be mazked with an "X" if [he sample was collected as an individual grab sample. 6. Station Location. This field should represent the complete sample name; although in some instances, it may be similar to the "STA. NO." field. An example of a complete sample name is "SB-3 (0.5-1.0)," where the 0.5-1.0 represents the depth interval in feet from where the sample was collected. Please note it is very important that the use of hyphens in sample names and depth units (i.e., feet or inches) remain consistent for all samples entered on the chain-of-custody form. Sample names may also use the abbreviations "MS/MSD," "FB," "TB," and "DUP" as prefixes or suffixes to indicate that the sample is a matrix spike/matrix spike duplicate, field blank, trip blank, or field duplicate, respectively. 7. Number of Containers. This field represents the number of containers collected at the sampling location to be submitted for analysis. 8. Analytical Parameters. The analytical pazameters that the samples are being analyzed for should be written legibly on the diagonal lines to the right of the "number of containers" column. As much detail as possible should be presented to allow the analytical laboratory to properly analyze the samples. For example, polychlorinated biphenyl (PCB) analyses may be represented by entering "PCBs" or "Method 8082." Multiple methods and/or analytical parameters may be combined for each column (e.g., PCBs/VOCs/SVOCs or 8082/8260/8270). These columns should also be used to present project- specific parameter lists (e.g., Appendix IX+3 target analyte list or MADEP SW-846). Quality assurance/quality control (QA/QC) information may also be entered in a sepazate column for each parameter (e.g., PCBs - MS/MSD) to identify a sample that the laboratory is to use for a specific QA/QC requirement. Each sample that requires a particular parameter analysis will be identified by placing an "X" in the appropriate analytical pazameter column. iireros 2 SOPo3-Sample Custody, Hantlling, Lacking. and Shipping-Mine.tlac
