• 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 /> • <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 <br /> nuinmum, the sample designation (including the depth at which the sample was collected), <br /> sample type, analytical request, date of sampling, and the name of the sampler The record <br /> sheet was signed, timed, and dated by the sampler when transferring the samples The <br /> number of custodians in the chain of possession was minimized A copy of the ARCO <br /> chain-of custody record was returned to EMCON with the analytical results <br /> SAG\N\PJMSOM051440 2DS-96,pac 1 A-5 Rev 0,1/24/96 <br />
