OFFICE OF WATER QUALITY TECHNICAL MEMORANDUM 87.03

Subject:  EQUIPMENT--pH Measurement in Low Conductivity 
                     Waters

The attached paper, "Some Recommendations and Comments on pH 
Measurement of Low Conductivity Waters," by Busenberg and 
Plummer, of the National Research Program, provides the new 
guidance on care and use of pH electrodes that we promised in 
Quality of Water Branch Technical Memorandum 85.13.

All who are involved in making pH measurements should find 
it of interest. And those who are working with low 
conductivity waters will find this information essential.

The authors intend to publish this paper as a Water-Resources 
Investigation Report.
