and often results in extended periods of flooding and 

 drought 1n these Regions. 



(3) Consumption of water other than for Irrigation is 

 bound to Increase at a high rate in resDonse to expected 

 population growth considerably above the national average. 



It should be noted, however, that these diversion projects may also 

 allow Increased control of water inflows that could be beneficial to 

 maintenance of existing estuarine productivity. Furthermore, some 

 proposed projects may merely shift the major portion of existing in- 

 flows from one area to another as in the case of the proposed diver- 

 sion of Delaware River inflow from Delaware Bay, through the Hudson 

 River, to Raritan Bay and Mew York Harbor. 



Municipal Wastes 



Municipal waste water disoosal is the most frequently cited example 

 of water quality degradation. The major impact of municipal waste 

 water discharge is calculated on the basis of the amount of 

 Biological Oxygen Demand (BOD), bacterial indicator organisms, gen- 

 erally coliforms, and suspended and dissolved solids reaching both 

 fresh and estuarine water. The magnitude of the future extent of the 

 water pollution problem is indicated by the projection that even if 

 secondary treatment were provided for all urban and sewered popula- 

 tion in the United States by 1980, the amount of residual wastes 

 reaching the Nation's waters would be about the same as today when
