GEUR <br /> • GENESIS ENGINEERING&REDEVELOPMENT <br /> • Name, address, and telephone number of laboratory <br /> Sample coolers will be sealed in the field with the completed Chain-of-Custody document <br /> inside the cooler and the express shippers (e.g., Federal Express) shipment forms filled out in <br /> the field and attached to the cooler at that time. The Chain-of-Custody record will have the <br /> signature of the relinquishing field geologist and the shipper's form document tracking <br /> number written on the comment line. <br /> The completed Chain-of-Custody form will be placed in a plastic bag and taped to the <br /> underside of the cooler lid. The cooler will be tightly bound with filament tape. Custody <br /> seals will be signed by the individual relinquishing custody and affixed in such a way that the <br /> cooler cannot be opened without breaking the seals. <br /> 3.3.2 Custody Seals <br /> Custody seals will be preprinted, adhesive-backed seals with security slits designed to break <br /> if disturbed. Custody Seal Numbers will be assigned in the field and will consist of an <br /> unique four digit number which will legibly printed on the seal using permanent waterproof <br /> • ink. Field personnel will maintain a record of the Custody Seal Numbers to assure that no <br /> numbers are used more than once. Sample shuttles (i.e., coolers) shall be sealed with two <br /> custody seals. Seals will be signed and dated before use. Upon receipt by the laboratory, the <br /> Laboratory Sample Custodian will check and certify,by completing logbook entries,that the <br /> seals are intact. <br /> 3.4 Quality Control Samples <br /> Quality Control samples are collected and analyzed for the purpose of assessing the quality <br /> of the sampling effort and the analytical data. Quality Control samples will include field <br /> duplicates and equipment blanks. <br /> A duplicate sample is a single soil sample divided into two equal parts from a single <br /> sampling location. Field duplicates will be identified so that laboratory personnel are unable <br /> to distinguish them from field samples. Duplicate samples will be collected at a frequency of <br /> I per every 10 or fewer(10%) field samples per matrix;with a minimum of one duplicate <br /> sample collected per sampling day. Duplicate samples are to be analyzed utilizing the same <br /> types of analyses as their associated field samples. <br /> An equipment blank is a sample of the final rinse water following decontamination of <br /> equipment. Equipment blanks will be analyzed for the same parameters as the soil samples. <br /> Equipment blanks will be collected at a frequency of 1 per 20 or fewer field samples(5%). <br /> • William DePaoli Property 9 of I I <br /> Sampling and Analysis Plan <br /> February 2012 <br />
