1 laboratory supplying the de-ionized, distilled water will perform <br />i ' an analysis on each lot to demonstrate that the water is analyte <br />free. <br />3.3.3 Rinse Blanks: Prior to any sampling, and at every fifth sample, <br />a rinse blank will be collected. Rinse blanks will be collected <br />' from the sampling equipment, e.g, the filling bucket. <br />After cleaning, using the procedure as outlined in this protocol, <br />a final rinse of de-ionized, distilled water will be collected. <br />' The analytical laboratory performing the analysis will supply the <br />de-ionized, distilled water which is to be used for rinse blanks. <br />' The laboratory supplying the de-ionized, distilled water will <br />perform an analysis on each lot to demonstrate that the water is <br />analyte free. Analysis of this rinse blank will be used to <br />' evaluate the equipment cleaning procedure. <br />' 3.4 Record Keeping <br />' All field data will be recorded in the Field Data Collection <br />Sheets. These data will include: weather conditions, field water <br /> quality parameter data, station number or location, the number of <br />' sample bottles to be obtained, the sequence in which the samples <br /> were taken and t he sampler's name. A Field Data Collection <br />' Checklist will a lso be filled out for each sample site to <br /> demonstrate that appropriate protocols were followed. The <br />' Checklist form is shown in Appendix B. <br />' A chain of custody will be implemented during sample collection, <br />which will be filed with the laboratory indicating the parameters <br />requested, as well as the collection date of the sample. <br />Prior to off-site shipment, samples will be inspected as to whether <br />' they are tightly capped, and labeled properly.
