OFFICE OF WATER QUALITY TECHNICAL MEMORANDUM NO. 86.08

Subject:  Issue Paper on Solid Phase Data in the Water Resources 
          Division

The enclosed issue paper on solid-phase data in the Water 
Resources Division is a revision of a draft prepared one year ago, 
and discussed and critiqued by several WRD geochemists.  The 
Office of Water Quality is distributing this paper now in order to 
give wider exposure to these ideas and to get responses from you, 
pro and con, to its many points.

The Surface Water Toxics Program has focused new attention on the 
solid phase, but the Regional Aquifer-System Analysis program and 
many individual projects over the years have also demonstrated the 
utility of data on the solid phase to improve our understanding of 
hydrologic processes.  Because the Division's access to solid-
phase data is limited at best, the arguments and proposals in this 
paper require careful consideration.

Please send your comments and suggestions on the ideas expressed 
in this paper to R. Schoen at Mail Stop 4l2, (RSCHOEN@QVARSA) by 
September 30 so that we can consider them in program planning.
