Significance and Use4.1 When sampling groundwater monitoring wells, it is very important to thoroughly document all field activities. Sufficientfield data should be retained to allow one to reconstruct the proc
17、edures and conditions that may have affected the integrity of asample. The field data generated are vital to the interpretation of the chemical data obtained from laboratory analyses of samples.Field data and observations may also be useful to analytical laboratory personnel.4.2 Due to the changing
18、nature of regulations and other information, users are advised to thoroughly research requirementsrelated to packaging and shipping prior to initiating a sampling event.NOTE 1The sampling of an individual groundwater monitoring well should be repeated as closely as possible each time the monitoring
19、well issampled. This reduces the variability of the chemical parameters due to sampling variability which is the desired result. The intent is to detect the changein chemistry by repeating the sampling protocol at each individual well. This does not mean that all the wells are sampled the same way,
20、nor does itprohibit changes in the sampling protocol, provided they are planned and documented.5. Documentation Methods5.1 Field records should be generated by a member of the sampling team. It is important to record procedures used andmeasurements immediately after they have been accomplished and a
21、re fresh in the memory. In general, notes should not be takenafter returning from the field.5.2 The format of the documentation is discretionary, but should be consistent from well to well and in accordance withregulatory requirements. Forms are often used for consistency and to reduce the chance of
22、 failing to record needed information.It may be desirable for records to be entered with indelible ink in a hard cover, stitch-bound book for credibility in litigation.6. Documentation Content6.1 General:6.1.1 Record the facility or site name, or both, and the well identification.6.1.2 Record the we
