much of this population is not served by secondary treatment faci- 

 lities. From approximate coefficients developed by the Federal 

 Water Pollution Control Administration for municipal wastes gen- 

 erated by man in areas served by sewers, a rough estimate of the 

 overall yearly municioal sewered waste loads may be computed for 

 the estuarine zone as shown in Table IV. 4. 9. 



Although these figures are approximate, and understate the magnitude 

 of the municipal waste load in the estuarine zone, they indicate the 

 tremendous pressure increasing population itself will place on the 

 water quality of the estuarine zone in the future. It does not take 

 into account the Increasing use of high water use appliances such as 

 washing machines, dishwashers, and garbage disposals which will con- 

 tribute significantly to higher per capita water wastes in the 

 future.
