Field Logbook <br /> In the field, the sampler recorded the follownng information on the water sample field data sheet <br /> (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 <br /> turbidity, sediment) <br /> Well accessibility and integnty • Results of field analyses (temperature, pH, <br /> Specific conductance) <br /> • Pertinent well data (e g , casing diameter, <br /> • 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 /> Labels <br /> Sample labels contained the following information <br /> • Project number • Sampler's initials <br /> • Sample number(i e , well designation) • Date and time of collection <br /> • Sample depth • Type of preservation used (if any) <br /> Sampling and Analysis Chain-of-Custody Record <br /> The ARCO chain-of-custody record initiated at the time of sampling contained, at a minimum, the <br /> sample designation (including the depth at which the sample was collected), sample type, <br /> analytical request, date of sampling, and the name of the sampler The record sheet was signed, <br /> timed, and dated by the sampler when transferring the samples The number of custodians in the <br /> chain of possession was minimized A copy of the ARCO chain-of-custody record was returned to <br /> EMCON with the analytical results <br /> sACNN\PJM80MOS 1140 6Bs 96\cjb 1 Rev 0 10/10/'96 <br /> A-5 <br />
