Logbooks

1. Logbooks ALLprocedures involving the analyzers, samplers, and the site itself should be documented. As a rule of thumb, all information recorded on Excel forms should be documented in the logbook. Each entry should have enough information that it could “stand alone.” The logbook should be bound and page numbered. All logbook entries should be written in ink, signed, and dated. Corrections to the logbook should be made with a single line through the entry, the site operator’s initials, and the date of the correction.
