These figures are reasonable statements of pressures from urban 

 poDulatlons, but the exterior suburban and rural populations pre- 

 sently not served by sewers will undoubtedly contribute further 

 significant liquid-bearing wastes to the estuaries. For example, 

 beach front and estuarine communities, particularly resort-oriented 

 developments, have traditionally and continue to depend 1n large 

 degree on septic tank disposal of municipal wastes. Problems of 

 waste seepage from seDtlc treatment have been noted 1n such places 

 as the north and south shores of Long Island, Florida resort and 

 retirement communities, and the Delaware-Maryland-Vlrginia shoreline. 

 Furthermore, many coastal communities were originally sewered with 

 primary treatment facilities. These facilities, often discharqing 

 directly Into shallow back bays, are no lonqer adeouate to meet 

 increased develoDment, density pressures and the lonqer duration of 

 stays caused by burgeoning "second home" markets. The communities, 

 limited to residential tax bases, are hard-Dressed to finance facili- 

 ties adequate to handle peak loads reached for relatively short 

 periods 1n the critical summer months. 



A final indicator of the magnitude of the municipal waste problem is 

 provided by Table IV. 4. 10. The marine coastal states are projected to 

 require an outlay of five and one-half billion dollars between 1969 

 and 1973 to adequately treat municipal wastes during that period. 

 This represents 63 percent of the national total of 8.693 billion pro- 

 jected for 1969 through 1973. The estuarine portions of the marine 

 states (basically the coastal counties) are estimated to require 60 

 percent of the Marine states' total outlay, or something over two and
