Site-Specific Health and Safety Plan (HASP) - Laschools.org

3.2 CALIBRATION PROCEDURES AND FREQUENCY FOR FIELD TEST
EQUIPMENT
Instruments and equipment used to gather, generate, or measure environmental data will
be calibrated according to manufacturer’s specifications with sufficient frequency to
ensure accuracy and reproducibility of results.
3.3 REVIEW OF FIELD RECORDS
Field record review is an ongoing process. Field team leaders will be responsible for
ensuring that proper documentation is recorded during each site's sampling activities.
Field records include logbooks, log forms, and any documentation, whether electronic or
hardcopy, that is used to record data, observations, assumptions, or other information in
the field. The sections below describe the items used for evaluation.
3.3.1 Completeness of Field Records
The check of field record completeness will ensure that all requirements for field
activities in the work plan have been fulfilled, complete records exist for each field
activity, and the procedures specified in the work plan (or approved as field change
requests) are implemented. Field documentation will ensure sample integrity and provide
sufficient technical information to recreate each field event. The results of the
completeness check will be documented, and environmental data affected by incomplete
records will be identified in the technical report.
3.3.2 Identification of Valid Samples
The identification of valid samples involves interpretation and evaluation of the field
records to detect problems affecting the representativeness of environmental samples.
For example, field records can indicate if unanticipated environmental conditions were
encountered during field activities. Records should note sample properties such as
clarity, color, and odor. Photographs may show the presence or absence of obvious
sources of potential contamination (during sampling). Judgments of sample validity will
be documented in the technical report, and environmental data associated with poor or
incorrect field work will be identified.
3.3.3 Identification of Anomalous Field Test Data
Anomalous field data will be identified and explained to the extent possible. Anomalous
data will be assessed for usability and explained in the technical report.
3.3.4 Accuracy and Precision of Field Data and Measurements
The assessment of the quality of field measurements will be based on instrument
calibration records and a review of any field corrective actions. The accuracy and
precision of field measurements will be discussed.
