QUALITY OF WATER BRANCH TECHNICAL MEMORANDUM 71.06

Subject: WATER QUALITY - Analytical methods

Water Resources Division Memorandum No. 71.72 dated 
November 24, 1970, outlined Division policy regarding the use 
of analytical methods by Division laboratories and 
established procedures for recommending new or improved 
methods for Division use.

Two methods not contained in the manual for inorganic 
analytical methods (TWRI, Book 5, Chapter Al) have been 
tested and approved by the Analytical Methods Unit and the 
Branch for immediate use by all Division laboratories. These 
methods, the mercuric thiocyanate colorimetric method for the 
determination of chloride and the SPADNS method for the 
determination of fluoride (copies attached), should be added 
to the manual.
