• Document all pre-trip and daily instrument calibrations on appropriate form and add to the <br /> laboratory equipment calibration log in the NS laboratory. <br /> • Record results obtained, observations made, the review of the results; nonconformance <br /> should be recorded as noted. <br /> • Record temperature, weather, humidity, wind speed and direction, or other environmental <br /> influences that might affect the results. Note — relative comments such as: windy, slightly <br /> breezy, muggy, light drizzle are acceptable. <br /> • Document variances from planned activities. A variance is considered to be a deviation <br /> from "shall," "must," or "will' statements of a procedure. <br /> • Sampling entries must include date and time of sample collection and water quality <br /> parameters. <br /> • Verify that all sections of the Field Data Form have been completed through the "Signature <br /> of Technician" before leaving the sight. <br /> B.1.6. Review of Field Data Books <br /> Field Data Books will be reviewed for content, accuracy, legibility, calculations, error correction, <br /> and reproducibility. The reviewer will check for completeness, validity of data, and traceability <br /> between each page and the items or activities to which it applies. The reviewer will take action <br /> to correct any deficiencies. Once the reviewer is satisfied with the data on the sheets, he/she <br /> must sign and date the bottom of each Field Data Sheet. <br /> B.2. Standard Practice for Sample Labeling <br /> B.2.1. Scope <br /> This procedure addresses labeling requirements and recommended practices for labeling <br /> samples that are collected in the field and intended for analysis at a later time. <br /> This procedure is intended for use with a variety of sample types, including grab samples, <br /> equipment blanks, duplicate samples, and split samples unless otherwise noted. All samples <br /> collected by the sampling technician shall have a sample label and a technician-generated <br /> sample number (well name). <br /> B.2.2. Terminology <br /> Chain of Custody Form — Form used to document sample custody and receipt. It also may <br /> contain other information, such as the sample analyses required and traceability. <br /> Field— any place where the material for analyses or testing is collected. <br /> Duplicate samples — More than one sample collected from the same source location, but <br /> placed in separate containers. <br /> Sample — A portion of material collected from a larger mass that represents the characteristics <br /> of that mass. <br /> Daub &Associates, Inc.
