CIIAIN OF CUSTODY SamploA are continuously maintained in either a chiliad ice cheat, refrigerator, or freezer from the* time of collection until acceptance by the States cnrtifled linzardous Materials Testing Laboratory selected to perform the ;lnalyticnl procedures, If the samplers are taken charge of by a different party (such as another person from our office, a courier etc.) prior to being delivered to the laboratory, appropriate release and acceptance records are made on the chain of custody (time, date, and signature of person releasing the samples followed by the time, date and signature of the person accepting custody of the samples). LABORATORY IDENTIFICATION NUMBERS , Following receipt of the samples and completion of the Chain of Custody form, the laboratory then assigns their awn identification numbers to the snnspic Different laboratories use different numbering systems and, according to their own internal conventions, may or mny not assign sequential numbers to E samples which are placed on temporary "hold", pending the results of other analyses. Laboratory identification numbers (if assigned and available) are included in the TABLE, and will be found on the certified analytical report F by the analytical laboratory. b CERTIFIED ANALYTICAL REPORT The certified analytical report (CAR) generated by the laboratory is the official document in which they issue their findings. The Results of Analyses section of the TABLE OF SAMPLING LOCATIONS AND ANALYTICAL RESULTS should correspond exactly with the laboratory's CAR. Any discrepancy between analytical values should be decided in favor of the CAR, for while it may, i itself, be in error with regard to a particular number, the CAR remains the recognized document until such time as it Is amended with a corrected report. The certified analytical report should also be reviewed whensamrlex two taken from below wamte oil tanks as any detection of the FI'A halogenated and ptargeala.c aromatic compounds may be grotinds for requiring further action. 7 Also the TAKE OF SAMPLING LOCATIONS AND Al:ALYTICAI.
