and other renewable resources. 



Restrictive impacts may involve damage to water quality, living 

 organisms, or aesthetic quality; such impacts may also result 

 from the exclusive appropriation of space. The key feature 

 of uses which cause restrictive impacts is that they may, with 

 proper management, be carried out simultaneously with other uses. 



Liquid Waste Disposal 



Although not generally regarded as a beneficial use, the 

 discharge of liquid wastes to estuarine waters is and is likely 

 to continue to be one of the major universal uses of the estuarine 

 zone. The present discussion considers liquid waste disposal 

 as one of many uses of the estuarine environment which has the 

 potential of conflicting with other uses but which will probably 

 have to be accomodated within the overall use patterns of nearly 

 all estuarine environments. 



The major restrictive impacts of liquid wastes arise from the 

 disposal of untreated or inadequately treated wastes in massive 

 quantity to estuarine waters. The discussion in Part IV, 

 Chapter 5, pointed out the various pollutional effects different 

 types of municipal and industrial wastes can have, and presented 

 some typical examples of pollutional effects. Six types of 

 impacts tend to restrict other uses:
