APPENDIX C<br />

4.1.6 Comparability<br />

Comparability is an expression of the confidence with which one data set can be compared with another.<br />

4.1.6.1 Measures to Ensure Comparability of Field Data<br />

Comparability is dependent upon the proper design of the sampling program and will be satisfied by<br />

ensuring that the FSP (Appendix A of the BWP) and project specific addenda is followed and that proper<br />

sampling techniques are used.<br />

4.1.6.2 Measures to Ensure Comparability of Laboratory Data<br />

Planned analytical data will be comparable when similar sampling and analytical methods are used and<br />

documented in the QAPP. Comparability is also dependent on similar QA objectives. To optimize<br />

comparability, EPA-established methods and protocols will be used whenever possible to collect and<br />

analyze samples. By using specific sampling and analytical procedures, including the reporting of the<br />

analytical data using common standard units, all data sets will be comparable at each specific site at<br />

Kirtland AFB and between sites at Kirtland AFB to ensure that decisions and priorities are based on a<br />

consistent database.<br />

All solid matrix results for the specified analytical methods will be reported on a dry weight basis. All<br />

organic analyses will be reported as micrograms per kilogram for soil and milligrams per liter (mg/L) for<br />

water; most inorganic analyses will be reported in milligrams per kilograms for soil and mg/L for water;<br />

and radiological data will be reported in picocuries per gram for soil and picocuries per liter for water.<br />

4.1.7 Completeness<br />

Completeness is a measure of the amount of valid data obtained from a measurement system compared to<br />

the amount that was expected to be obtained under normal conditions.<br />

4.1.7.1 Field Completeness Objectives<br />

Field completeness is a measure of the amount of valid measurements obtained from all the<br />

measurements taken in the project. The equation for completeness is presented in Section 13.0 of this<br />

QAPP. Field completeness objectives for Kirtland AFB projects will be greater than 90 percent.<br />

4.1.7.2 Laboratory Completeness Objectives<br />

Laboratory completeness is a measure of the amount of valid measurements obtained from all<br />

measurements taken in the project. The equation for completeness is presented in Section 13.0 of this<br />

QAPP. Laboratory completeness objectives for projects will be greater than 95 percent.<br />

2.14 Level of Field Quality Control Effort<br />

Equipment rinse blank, trip blank, ambient field blank, and QA replicate samples will be collected and<br />

analyzed on a project-specific basis to assess the quality of the data resulting from the field sampling and<br />

analytical programs. Equipment rinse blanks consisting of distilled water will be submitted to the<br />

analytical laboratories to provide the means to assess the quality of the data. Equipment blank samples<br />

will be analyzed to check for potential contamination resulting from improper decontamination<br />
