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 /> i <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 /> turbidity, sediment) <br /> • Date and time <br /> • Results 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 sampling <br /> coordinator <br /> SAC\N\PJM805\08051440 SAA 95\pra i A-5 Rev 0,5/12/97 <br />
