• <br /> Sample Documentation <br /> The following procedures were used during sampling and analysis to provide chain-of- <br /> custody control during sample handling from collection through storage. Sample <br /> documentation included the use of the following: <br /> • Water sample field data sheets to document Chain-of-custody record sheets for <br /> sampling activities in the field documenting possession and transfer of <br /> samples <br /> • Labels to identify individual samples <br /> • Laboratory analysis request sheets for <br /> documenting analyses to be performed <br /> Field Logbook <br /> In the field, the sampler recorded the following information on the water sample field data <br /> sheet (see Figure A-2) for each sample collected: <br /> • Project number • Calculated and actual purge volumes <br /> • Client's name • Purging equipment used <br /> • Location • Sampling equipment used <br /> • Name of sampler • Appearance of each sample (e.g., color, <br /> • Date and time turbidity, sediment) <br /> • ResuIts of field analyses (temperature, pH, <br /> • Well accessibility and integrity specific conductance) <br /> • Pertinent well data (e.g., casing diameter, • General comments <br /> depth to water, well depth) <br /> The water sample field data sheet was signed by the sampler and reviewed by the <br /> sampling coordinator. <br /> i <br /> CM:\QMR�,3RDQ1R-112186Q398.DOC-98Usg:1 A-5 Rev.0,11/30/98 <br />
