AWES, LLC <br />•Raise the bailer by grasping a section of cord, using each hand alternately. This bailer lift method will <br />assure that the bailer cord will not come into contact with the ground or other potentially <br />contaminated surfaces. <br />Sampling <br />Instructions for obtaining samples for parameters are reviewed with the laboratory coordinator to insure that <br />proper preservation and filtering requirements are met. <br />•Appropriate sample containers will be obtained from the contract laboratory. After samples are <br />collected, they will be put on ice in coolers (4°C). Care will be taken to prevent breakage during <br />transportation or shipment. <br />•Samples collected by bailing will be poured directly into sample containers from bailers. The sample <br />should be poured slowly to minimize air entrapment into the sample bottle. During collection, <br />bailers will not be allowed to contact the sample containers. <br />•Upon completion of sampling a chain-of-custody log will be initiated. Chain-of-custody records will <br />include the following information: project name and number, shipped by, shipped sampling point, <br />location, field ID number, date, time, sample type, number of containers, analysis required and <br />sampler’s signature. The samples and chain-of-custody will be delivered to the laboratory. Upon <br />arrival at the laboratory the samples will be checked in by the appropriate laboratory personnel. <br />Laboratory identification numbers will be noted on the chain-of-custody record. Upon completion of <br />the laboratory analysis, the completed chain-of-custody record will be returned to the project <br />manager. <br />Field Cleaning Procedures <br />For all equipment to be reused in the field, the following cleaning procedures must be followed: <br />•Disassemble the equipment to the extent practical. <br />•Wash the equipment with distilled water and laboratory-grade detergent. <br />•Rinse with distilled water until all detergent is removed. <br />•Rinse the equipment with isopropyl or methanol, making sure all surfaces, inside and out, are <br />rinsed. <br />•Triple rinse the equipment with distilled water. <br />Laboratory Selection <br />The project manager should consider the following factors when selecting a laboratory: <br />•Capabilities (facilities, personnel, instrumentation), including: <br />•Participation in interlaboratory studies (e.g., EPA or other Federal or State agency sponsored <br />analytical programs); <br />•Certifications (e.g., Federal or State); <br />•References (e.g. other clients); Experience. <br />•Turnaround time; and <br />•Technical input (e.g., recommendations on analytical procedures).
