QUALITY OF WATER BRANCH TECHNICAL MEMORANDUM NO. 85.05

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

A quality-assurance report for the Central Laboratories-
Atlanta and Denver-for the period April 1 throuih June 30, 
1984, is attached.  The report covers quality-assurauce 
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.  Special attention should be directed to the 
"discussion and recommendations" section of this report.  
This section provides qualifications necessary for 
interpreting the information provided in tabular and graphic 
form.

Quality-assurance reports covering previous time periods are 
on file in the Quality of Water Branch.
