SAMPLE HANDLING AND DOCUMENTATION This section presents the requirements for handling, labeling, and transport of water samples and field recording practices necessary for reconstruction of the sampling event. SAMPLE DOCUMENTATION Information pertinent to the sampling effort will be recorded on the Liquid Substance Sampling Forms (Figure A-1). Any pertinent information that is not included on this form will be documented in a bound field logbook. All entries will be made in indelible ink and all corrections will follow error correction protocol of one line through the error and initial and date of correction. At a minimum, entries on the field records shall include the following: • Purpose of sampling • Location, description, and available photographs of the sampling point • Details of the sampling site (for example, condition of station, weather, etc.) • Documentation of procedures for preparation of reagents or supplies which become an integral part of the sample (e.g., filters and preservatives) • Identification of sampling crew members • Type of sample (e.g., ground water, surface water, soil, etc.) • Number and volume of sample taken • Sampling methodology • Sample preservation • Date and time of collection • Collector's sample identification number(s) • References such as maps of the sampling site • Field observations • Any field measurements made (e.g., pH, specific conductance, temperature and water depth) • Date and signature of the personnel responsible for observations • Decontamination procedures Sampling situations vary widely. No general rules can specify the extent of information that must be recorded. However, records shall contain sufficient information so that someone can reconstruct the sampling activity without relying on the collector's memory. The field records shall be kept under strict chain-of-custody and stored in a location so as to make it accessible to the project QA Coordinator.
