%✓ %0011 is required for these samples. The samples will be chilled to 4°C immediately upon collection. Two bottles of each groundwater sample are required for each laboratory. CLPAS Metals. Low concentration groundwater samples collected for CLPAS metals analysis will be collected in 1-liter polyethylene bottles with nitric acid (HNO3). 8.3 Sample Chain-Of-Custody Forms and Custody Seals Chain-of-custody records will be used to document sample collection and shipment to laboratory for analysis. All sample shipments for analyses will be accompanied by a chain-of-custody record. A copy of the form is found in Appendix D. Form(s) will be completed and sent with the samples for each laboratory and each shipment (i.e., each day). If multiple coolers are sent to a single laboratory on a single day, form(s) will be completed and sent with the samples for each cooler. The chain-of-custody form will identify the contents of each shipment and maintain the custodial integrity of the samples. Generally, a sample is considered to be in someone's custody if it is either in someone's physical possession, in someone's view, locked up, or kept in a secured area that is restricted to authorized personnel. Until the samples are shipped, the custody of the samples will be the responsibility of BASELINE Environmental or Black & Veatch. The site leader or designee will sign the chain-of-custody form. The site leader or designee will sign the "relinquished by" box and note date, time, and air bill number, if appropriate. A quality assurance/quality control (QA/QC) summary form will be completed for each laboratory and each matrix of the sampling event. The sample numbers for all trip blank samples, laboratory QC samples, and duplicates will be documented on this form (see Section 9.4). The original form will be sent to the QA Program; a photocopy will be made for the BASELINE Environmental and Black & Veatch master files. This form is not sent to the laboratory. The shipping containers in which samples are stored (usually sturdy picnic cooler or ice chest) will be sealed with self-adhesive custody seals any time they are not in someone's possession or view before shipping. All custody seals will be signed and dated. 8.4 Labeling, Packaging, and Shipment All samples collected will be labeled in a clear and precise way for proper identification in the field and for tracking in the laboratory. A copy of the sample label is included in Appendix D. The samples will have preassigned, identifiable, and unique numbers. At a minimum, the sample labels will contain the following information: station location, date of collection, analytical parameter(s), and method of preservation. Every sample, including samples collected from a single location but going to separate laboratories, will be assigned a unique sample number. n:1352101985APlwebsap2.wp5 WEBER BLOCK (Area 9) Sampling and Analysis Plan Q Page 19
