Holding Times. The laboratory shall notify the appropriate City Project Manager or designee immediately on discovery that holding time(s) have been exceeded so that re-sampling can take place. The decision on analysis of such samples will be made upon notification. The City reserves the right to recover cost of re-sampling due to the Contractor failing to meet sample holding times, provided that the Contractor has had possession of the sample for at least fifty (50 ) percent of the sample holding time. The exception to this would be in the case of coliform samples where the Contractor will only be liable if the Contractor was not notified of sample pick up within two hours of the time of the sampling. Re-sampling will be billed to the Contractor at the rate of the City's cost plus standard overhead cost or one hundred ($100.00) dollars, whichever is greater.
Holding Times. A holding time is defined as the allowable time between sample collection and analysis and/or extraction recommended to ensure accuracy and representativeness of analysis results, based on the nature of the analyte of interest and chemical stability factors. The holding time is calculated from the date and time of sample collection to the time of sample preparation and/or analysis. Sample holding times are established to minimize chemical changes in a sample prior to analysis and/or extraction. In general, there are no holding time requirements for asbestos. Ashing the tissue samples will address any concerns with holding times for the medium.
Holding Times. In general, there are no holding time requirements for asbestos. Because sample preparation (see Section B4.1) will include techniques to address any issues related to holding time for the media (i.e., ashing of tree bark and duff samples will address the growth of organic material that may occur between sample collection and sample analysis), there are no holding time requirements for samples collected as part of this sampling program.
Holding Times. As specified by EPA protocol, the sampling, extraction, and analysis dates will be reviewed to confirm that extraction and analyses were completed within the recommended holding times. Appropriate data qualifiers will be noted if holding times are exceeded. Table 2 contains the current EPA method holding times.
Holding Times. Samples received passed the established holding time shall not be analyzed without written consent from the CLIENT. (This does not include samples for testing methods with fifteen minute or “as soon as possible” holding times.) Samples held by the CLIENT and delivered to BASIC LAB with minimal holding time remaining will incur additional fees, or may be rejected.
