It is <br />important that samples are packaged for transport once the sampling event is complete, and delivered <br />to the laboratory in order to arrive within the required holding time for each constituent. <br />5.4.1 Field Notebook. Field notes will be taken at sampling sites and recorded in a bound <br />field notebook. Observations and sampling methods will be recorded while at the sampling site to <br />improve accuracy. Types of information to be recorded include monitoring site identification, date <br />and time of sampling, identity of the sampler(s), type of samples, identification of QA /QC samples, <br />method of sampling, results of field analyses, description of weather, access conditions, air <br />temperature, site appearance, and unusual conditions observed. Calibration information will also be <br />recorded in the field notebook. <br />5.4.2 Sample Bottle Labeling. Collected samples will be designated by sample location (for <br />example, MW -001, MW -002). Each sample container will be individually labeled, with the label affixed <br />directly to the bottle itself with the preservative and analysis to be performed printed on the label. <br />Additional sampling information, including date, time, location, sampling medium, and sampler initials, <br />will also be written on the label with indelible ink. <br />5.4.3 Chain of Custody Documentation. COC documentation will identify sample <br />containers, include a complete inventory of containers in a sample set, and provide an audit trail <br />identifying the persons who have custody of a sample in order, and the date and time when custody was <br />relinquished from one person to the next. COC forms will be obtained from the analytical laboratory <br />with the sample bottles. <br />5.4.4 Sample Containment for Transport. Sample bottles collected in the field will be <br />labeled, double - bagged and placed in a plastic re- useable cooler with double - bagged ice for transit to <br />the appropriate laboratory. Samples will be kept chilled to 4 degrees Celsius in a cooler from the <br />time of collection through delivery to the analytical laboratory. Bubble wrap packing and air -filled <br />baggies will be used to fill the space in the cooler to minimize the chance for movement and damage <br />of the sample bottles inside the cooler. <br />P:\ Data\ GEN\ FS- P- T\22421 \Permimng \Supulation Response \Groundwater Sampling Plan \Condition 1 Groundwater Sampling Plan 3_24_03.doc <br />10 <br />
