QUALITY OF WATER BRANCH TECHNICAL MEMORANDUM NO. 82.11

Subject:  PROGRAMS AND PLANS--Central Laboratories Quality-
                              Assurance Report

A Quality-Assurance Report for the Central Laboratories--
Atlanta and Denver--for the period July 1 through September 
30, 1981, is attached.  This Report covers quality-assurance 
samples which were submitted daily to the laboratories 
through a program which is independent of the management of 
the Central Laboratories System.  The Report does not cover 
the quality-control samples within the laboratory sections or 
the quality-assurance samples submitted by each Laboratory 
Chief to his laboratory.

Because this quality-assurance program examines data after it 
has undergone routine Central Laboratory quality control 
checks and has been stored in WATSTORE, the report should 
reflect the quality of the analyses received by the data 
user.

A Quality-Assurance Report for the period October 1 through 
December 30, 1981, is in preparation.  Current plans are to 
issue quarterly reports plus a yearly summary which will be 
distributed as an Open-File publication.  Quality-assurance 
reports covering previous years are on file in the Quality of 
Water Branch.
