• Pertinent well data (e.g., well depth, water level, <br />water -surface elevation, casing diameter, and purge and <br />sample methods) <br />• Calculated and actual purge volumes <br />• Color of sample <br />• Appearance of each sample <br />• Analyses performed in the field (e.g., temperature, pH, <br />specific conductance) <br />• Sampler's name <br />• General comments (e.g., unusual weather conditions) <br />Each sample container will be labeled immediately after the sample is <br />taken. Label information will include the following: <br />• Sample number <br />• Sampler's identification <br />• Project number <br />• Data and time of sample collection <br />• Type of preservative used <br />The chain -of -custody records, initiated at the time of sampling, will <br />contain the following information: well number, date of sampling, and <br />the name of the person collecting the sample. Figure A-2 shows a <br />typical chain -of -custody record. The record sheet will be signed by <br />the sampler when transferring the possession of the samples. Custody <br />transfers will be recorded for each individual sample; for example, if <br />samples are split and sent to multiple laboratories, a record sheet <br />will accompany each sample.
