<br /> 2 <br />1 <br />4 F <br />l i <br /> . <br />. <br />ie <br />d Qual <br />ty Control Check: A thorough review of procedures will be <br />' made by <br />t <br />l the field sampling <br />i <br />i <br />h <br />b personnel to check that all quality <br />t <br />i <br /> con <br />ro prov <br />s <br />ons <br />ave <br />een me <br />. If any <br />tems are outside the <br /> control limits as defined in the above procedures, the field <br /> sampling personnel will take corrective action. The action taken <br /> shall be of a nature to return the sample back to within control <br />' limits. The corrective-action, decision-making process will <br />progress in a reverse sequence of the procedures listed above, in <br />' a descending order until the sample is within control limits. <br />Recollection of a sample will be the means of last resort to return <br />' a sample to within control limits. If there is a deviation from <br />the sampling procedure and/or sample management program, but this <br />will not sufficiently affect the integrity of the sample to warrant <br />' recollection, the sample will continue through the sample <br />management sequence. The field sampling personnel will Notify the <br />' Project Manager of this situation. In addition, any such <br />deviations from procedure must be noted. <br />2.L5 Filtration of Ground Water Samples. Preservation and Preparation: Ground <br />water samples requiring dissolved analysis will be filtered on <br />site. Filtering techniques are defined in Section 2.2.10. Samples <br />will be filtered with as little delay after collection as is <br />practical under field conditions. Samples requiring filtration <br />' will be acidified after filtering. Sample bottles that are <br />filtered will be recorded on the Field Data Collection Sheet. <br />' If conditions allow for same day delivery to the laboratory, the <br />samples may be filtered at the laboratory, providing filtration is <br />' performed promptly upon receipt by laboratory personnel. Samples <br />will not be acidified in the field but, rather, will be $cidified <br />' at the laboratory following filtration. Time and date of <br />filtration will be recorded by the laboratory. <br /> <br />LJ <br />-7- <br /> <br />
