STATEMENT OF JOSEPH L. McCARTHY 



PROFESSOR IN CHEMICAL ENGINEERING 

 UNIVERSITY OF WASHINGTON 



PROFESSOR MCCARTHY: Mr. Stein, Mr. Poston 

 and Mr. Harris, ladies and gentlemen. 



My name is Joseph McCarthy. I am a Professor 

 in Chemical Engineering at the University of Washington, 

 and for about the last two decades I have served as the 

 principal investigator of the Pulp Mills Research Project 

 which has been conducted at the University of Washington 

 under the sponsorship of the Northwest Pulp and Paper 

 Association. 



I wish to comment today on the results of 

 investigations which have been conducted as part of this 

 program, that is particularly investigations which have 

 been carried out on the Pearl-Benson or nitroso method 

 for the estimation of sulfite spent liquor concentration 

 in fresh and salt waters, a procedure which I believe, 

 incidentally, was introduced and first used by Professor
