Laboratory Data Records Review (LDRR)
Client: Westinghouse Savannah River Company
The client requested that we perform quarterly LDRRs for several of their contract analytical laboratories that provide groundwater and soils analyses results. The LDRR was to include review of both process-specific and sample-specific information.
Our reviews included
The process-specific reviews were conducted using process review forms and data records review checklists. The sample-specific reviews were conducted using data records review forms and checklists. We also reviewed sample documentation for every analyte reported, selecting one or two samples per matrix per month depending on the analytical method. We provided the client with written reports of the LDRR results for each laboratory.
