OFFICE OF WATER QUALITY TECHNICAL MEMORANDUM NO. 92.04

Subject:  PUBLICATIONS--Revised Statement Regarding Dissolved
                        Trace-Element Data Production

This memorandum contains a revised statement on dissolved 
trace element data to be included in the State annual data 
reports.  Revision was requested by the Assistant Chief 
Hydrologist for Scientific Information Management who has 
policy oversight of Water Resources Division publications.

While the statement for reports is revised, the reasons for 
this statement, as discussed in the Office of Water Quality 
(OWQ) Technical Memorandum 92.03, remain unchanged.  Please 
include the following statement in State annual data reports 
for 1991:

    "Historical and current (19xx) dissolved trace-element
     concentrations are reported herein for water that was
     collected, processed, and analyzed by using either
     ultraclean or other than ultraclean techniques.  If
     ultraclean techniques were used, then those 
     concentrations are reported in nanograms per liter.
     If other than ultraclean techniques were used, then
     those concentrations are reported in micrograms per
     liter and could reflect contamination introduced
     during some phase of the procedure."



                              David A. Rickert
                              Chief, Office of Water Quality

Key words:  Water quality, annual reports, trace elements.
This memorandum supplements OWQ Technical Memorandum 92.03.
