Statement to the Sanitary Water Board of Illinois (Continued from Page 9) 
"For many years members of the Illinois Audubon Society have worked to 
help establish clean streams, We have been concerned over the problems posed 
by increased amounts of municipal and industrial wastes due to our increased 
population, We believe that through close enforcement of the laws, including 
the setting of water quality criteria standards, nature's gift of clean water 
can be restored, 
"Illinois Audubon members hope that criteria for the Rock River will set 
high enough standards to sustain wildlife, fish and aquatic life, and protect 
citizen health and recreation. We approve of the proposed standard of a 
minimim treatment of 90% of organic waste. 
"Special care should be taken to establish high enough standards so that 
industrial wastes, including cyanide are not a hazard, 
"Every citizen is profoundly affected by the quality of water supply. 
Although we cannot all be technical water experts, we know that clean water is 
essential to health, important for recreation and affects the economy and the 
taxes we pay."
