SOP6 – Water Quality Analysis

7.9. QAQC
A log is kept of each analysis conducted during vendor and validation trials. The information
includes what type of sampling, volume used, and when the samples were processed. The filter
log chain of custody tracks the samples from the field sites, to the storage site, and finally the
analytical laboratory. At each site, a MERC team member signs and dates the document. The
analytical laboratory also signs and dates the documents.
