The approved laboratory2 provides NS with pre -cleaned and pre -preserved sample bottles. In
addition, the laboratory handles the QA/QC protocols for all groundwater samples. NS
conducts all field sampling, field data collection, and sample collection. NS is responsible for
ensuring groundwater samples are delivered to the laboratory within the required hold times
and preservation techniques. Daub performs additional QA/QC by compiling all analytical data
and cross checking the data with historical values.
3.2 Field Measurements and Calibration
General methodologies for field measurements are located in Appendix B, Sections B.9 through
B.13. Calibration of field instrumentation will be conducted according to manufacturer's
recommendations, refer to Table 2 for basic calibration checks. If calibration acceptance
criteria are not met during the operational check, a primary calibration of the affected probe(s)
and instruments(s) must be conducted. Probe replacement or cleaning may also be required if
the operational acceptance criteria are not met, per the manufacturer's calibration
specifications.

4 Sample Identification and Handling Procedures
Each sample will be assigned an identifier that corresponds to each well name or surface
sample location. In addition, a unique Project ID will be assigned to each sample group
analyzed by the laboratory (See Section B.2, "Standard Practice for Sample Labeling," in
2 ACZ Laboratories, Inc. in Steamboat Springs, CO is currently contracted to NS for water sample
analyses.
