<br /> <br />' Following a sampling series of no more than 5 samples, a rinse <br />blank will be collected from the bucket, running laboratory- <br />provided de-ionized, distilled water throughout the entire bucket. <br />Analysis of this rinse blank will be used to validate cleaning <br />' procedures. <br />Immediately after collection, all samples must be placed in iced <br />coolers. The sample bottles required for each surface water sample <br />' are listed in Table 5. Sample preservation, pre-treatment and <br />holding times, as outlined in Table 5, will be strictly adhered to. <br />' 3.2.5 Field Parameter Measurements: Standard procedures should be <br />followed to maintain consistent measurements of field tDarameters. <br />These standard procedures are as follows: <br />' (1) Instruments should be calibrated at the beginning of each <br />sampling day, using a known standard solution. Field <br />instrumentation calibration procedures are documented in <br />Table 6. <br />' (2) The samples to be measured should be collected in a <br />t sample container that has been cleaned at bast twice <br />with the same water that is being measured. <br />' (3) A11 measurements should be made within as brief a period <br />of time as possible, so that temperature or chemical <br />' changes will be minimized. <br />' (4j In some cases, the instruments take a certain amount of <br />time to stabilize. This stabilization time should be <br />noted for each measurement. <br />1 <br />-23 <br />1 <br />
