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 • CaIculated 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 /> • Results of field analyses (temperature, pH, <br /> Well accessibility and integrity <br /> 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 /> CP\D:\QMR\ARCOIISTQ99\2186Q199.DOC-9811sg:1 A-5 <br /> Rev.d,4/26/99 <br />
