CGRS, Inc. <br />• Pour [he bailed groundwater into a bucket. Once the bucket is full, transfer the water to a barrel and <br />contain on-site. <br />• Raise the bailer by grasping a section of cord, using each hand alternately. This bailer lift method <br />will assure [ha[ [he bailer cord will not come into contact with the ground or other potentially <br />contaminated surfaces. <br />Samyline <br />Instructions for obtaining samples for parameters are reviewed with the laboratory coordinator to <br />insure that 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 <br />sample should be poured slowly to minimize air entrapment into the sample bottle. During <br />collection, bailers will not be allowed to contact the sample containers. <br />• Upon completion of sampling achain-ofcustody log will be initiated. Chain-of-custody records <br />will include [he following information: project name and number, shipped by, shipped sampling <br />point, location, field ID number, date, time, sample type, number of containers, analysis required <br />and sampler's signature. The samples and chant-ofcustody will be delivered to tfie laboratory. <br />Upon arrival a[ the laboratory the samples will be checked in by the appropriate laboratory <br />personnel. Laboratory identification numbers will be noted on [he chain-of-custody record. Upon <br />completion of the laboratory analysis, the completed chain-of-custody record will be returned to the <br />project 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 [he extent practical. <br />• Wash the equipment with distilled water and laboratory-grade detergent. <br />• Rinse with distilled water until ail 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 Se[ec[ion <br />The project manager should consider the Following factors when selecting a laborarory: <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 (c.g., Federal or State): <br /> <br />
