TM93-02 Review process for samples analyzed at the National Water Quality Laboratory (NWQL)

The purpose of this memorandum is to assist the District personnel in understanding the Quality Control (QC) review process that samples presently undergo at the NWQL prior to release. As the tools become available to implement major changes in the procedure, the Quality Management Group (QMG) will coordinate with District personnel and chemists to improve the data review process. The review process is explained for the inorganic and radiochemical samples. The organic review process will be explained in a future memorandum.
