1 <br /> Sample/data collection activities will be documented fully and accurately. Log books will be used <br /> ' to record mapping locations and specific considerations associated with sample acquisition, <br /> preparation, transportation, receipt by a certified laboratory and analysis to be performed on the <br /> sample. Sample locations will be surveyed so the exact sample locations will be known. In addition, <br /> ' logbooks will be used to record when and where photographs, temperatures, pressures, etc. are <br /> taken. Field sampling team will have at least one person designated as the Site Supervisor who will <br /> be thoroughly familiar with documentation procedures. The site supervisor will personally perform, <br /> or at least oversee, the completion of documents that accompany the samples. For consistency in <br /> data recording, whenever possible, one person on each field sampling team will record data. Using <br /> one person to record data will permit timely recording of observations, enable more data to be <br /> recorded, and minimize any chances of contaminating field records. <br /> ' Documentation in logbooks, sample tags, labels, custody seals and other accountable serialized <br /> documents will be completed with permanent reproducible ink. None of these documents will be <br /> destroyed or thrown away, even if the comments are illegible or if inaccuracies are recorded that <br /> must be replaced. The documents will be marked "VOID" and maintained by CGRS. CGRS will <br /> hold all documentation for 5 years subject to the availability of any other authorized person. <br /> t Document control means that controlled documents will receive review and concurrence as <br /> appropriate, the distribution of the documents will be recorded and revisions will be made in all <br /> distributed copies. The preparation, issuance and revisions of documents that specify quality <br /> requirements or prescribed activities affecting quality will be controlled to ensure that correct <br /> documents are used. Control will consist of item identification, secure storage and documented <br /> distribution. <br /> ' 2.0 Measurement/Data Acquisition <br /> ' 2.1 Sampling Process Design <br /> Soil for the column testing will be obtained from the site in the vicinity of the proposed pilot trench <br /> ' location. The gravel will be obtained at ten feet below ground surface (seven feet below the water <br /> table surface) which is the expected depth of the trench. This material would be representative of <br /> the gravel that would be in contact with the ash. <br /> ' Water used for the column leaching experiment will be obtained from the mined out quarry just <br /> upstream of the proposed trench location. The water will be collected near the soil water interface <br /> no less than 50 feet of the proposed trench location. <br /> ' Ashes used in this experiment will be the same ashes used in previous experiments, and as such, <br /> obtaining additional ash is not required. Ashes used for the field study will be the Cherokee 4 Fly <br /> ' Ash with Sodium and Class F Silo Ash with Gypsum. These ashes will be blended to a 50/50 <br /> mixture and used for the leaching experiment. <br /> Water quality samples obtained from the column leaching experiment will be obtained on a periodic <br /> ' basis in order to evaluate possible changes in water quality relative to pore volume effluent. <br /> Samples will be obtained at 1, 2, 4 and 8 pore volumes (calculated as the pore volume for the entire <br /> column at 1.5 liters). <br /> ' 2.2 Sampling Method Requirements <br /> Soil from the site will be obtained by using a backhoe. The backhoe will remove overburden as <br /> ' necessary to that a representative sample can be obtained from the desired depth. The soil will then <br /> be containerized and transported to the CGRS field office. <br /> ' Vama Companies <br /> Quality Assurance Project Plan <br /> Page 6 <br />
