Sample Documentation <br /> The following procedures were used during sampling and analysis to provide <br /> chain-of-custody control during sample handling from collection through storage. Sample <br /> documentation included the use of the following: <br /> o Water sample field data sheets to document o 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 /> a 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 /> a Project number a Calculated and actual purge volumes <br /> C Client's name o Purging equipment used <br /> o Location O Sampling equipment used <br /> Name of sampler • Appearance of each sample(e.g., color, <br /> m Date and time turbidity, sediment) <br /> • Results of field analyses (temperature, pH, <br /> a 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 sampling <br /> coordinator. <br /> SACIN:1PJ010805108051470.3AS-971cjb:I A-5 emcon <br /> Rev.0,6/6/97 <br />
