Sample Identification. Sample identifiers (labels) will be applied in accordance with the SOP SAS-03-01, which addresses the prefixes to be used for various sample types. In addition, xxxxx, borings, and other sampling locations have been assigned specific numbers based on the site. Although there are specific incidences at some of the sites where the well names/numbers do not follow the specified scenarios, this usually reflects sampling points that were conducted prior to the Consultant’s involvement at the site.
Sample Identification. Samples must be clearly identified by individual catch lot such that the following information is readily available on a tag (using a black indelible ink marker):
Sample Identification. The Sample Identification - Field Chain of Custody Record (SI-FCCR) in Appendix A4 or an approved equivalent will be completed. All primary and QA/QC samples collected at a given sampling point over a discrete interval of time will be assigned the same sample event ID. This ID is used to link that set of containers together and associate them with all of the information contained on the Sampling Form or approved equivalent. If the SI-FCCR is used, it will contain a unique record number printed in the upper margin on the right side of the form. If it is not used, the remainder of the paragraph may be disregarded. The container’s row # appended to the record # on the form uniquely identifies each sample. In the case of a multi-container set, such as a set of three associated VOC vials, the set is uniquely identified. Each sample container will be labeled with the following information using a waterproof marker on firmly affixed, water- resistant labels: • site name • unique container ID • sample collection Date • sample collection Time • initials of person 17 c-clf1- • collecting sample • parameters names/groups to be analyzed • preservation method Containers will be labeled at the sampling point at the time of sample collection with the following exceptions. For containers receiving preservatives in advance, “parameter names” and “preservation method” will be entered onto labels by laboratory staff. For containers receiving preservatives in the field, “preservation method” will be entered at the time individual containers are filled.
Sample Identification. LABORATORY shall have a specified method for maintaining identification of samples throughout the laboratory to assure traceability of samples while in possession of LABORATORY. Each sample and sample preparation container shall be labeled with the EPA Region III DAS number or a unique laboratory identifier. If a unique laboratory identifier is used, it shall be cross-referenced to the EPA Region III DAS number.
Sample Identification. LABORATORY shall have written SOPs regarding the assignment of unique laboratory identifiers (if this procedure is used by LABORATORY) including a description of the method used to assign the unique LABORATORY identifier and cross-reference to the EPA Region III sample number. LABORATORY shall have written SOPs on the assigning of prefixes or suffixes in addition to sample identification numbers (if this procedure is used by LABORATORY), including their definitions.
