STATEMENT BY STORES WATERMAN 



contains a table of water uses and limitation of parameters 

 to protect such uses. This table is a useful guide when 

 approaching an overall water quality standard, but choices 

 must be made when conflicting uses or natural conditions 

 do not permit the idealized condition indicated by the 

 chart to prevail. Reasonable departure from the ideal will 

 allow satisfactory multiple use of the water. A number of 

 terms in the chart need to be more adequately defined and 

 several present a quandary for implementation for instance, 

 when natural conditions do not satisfy the standards pro- 

 posed.

A review of Table I listing water uses for 



the waters in question both future and present, fails to 

 reveal any definite reference to the legitimate use of 

 water to receive effluents from industrial operations or 

 municipal treatment works even though such a use is implied 

 by the setting of certain of the standards. As technology 

 progresses there is a continually increasing effort being 

 made to re-use water. This is possible because of advanced 

 methods of treatment which not only make re-use more practi- 

 cal but also put waste water into better condition for dis- 

 posal. It is expected that this approach will continue to 

 grow and more and more industrial and municipal waste water 

 will be re-used. However at present it is not practical to
