The EDF Format is a method for transferring environmental laboratory data from one organization to the next, delivering fully defined data of known quality. EDF data includes:
Chain-of-Custody (COC) Information
- − sample collection information
- − administrative information
- − preservatives added to the samples
- − conditions of transport
Laboratory Results Information
- − tests performed
- − parameters tested
- − analytical results
Quality Assurance (QA) Information (key to data verification)
- − detection limits
- − control limits for precision and accuracy
- − validation flags
- − narrative report explaining non-conformances
EDF may be used for electronic data review, data quality summaries, or the production of hard copy reports. EDF is the electronic reflection of the legally defensible hard copy laboratory report.
