minor domestic or industrial waste categories, 

 and mapped the areas that are closed to shell- 

 fishing (Figs. 2-24) . Major sources of industrial 

 waste were considered to be those with a strength 

 of effluent exceeding 8,000 population equiva- 

 lents (see footnotes, Tables 7 and 8, for defini- 

 tions) ; major domestic wastes were those with 

 a flow in excess of four million gallons per day 

 (15 million liters per day). 



Figure 44 illustrates the distribution of pol- 

 lution sources. Underlined place names and 



solid black indicate areas that are closed to 

 shellfishing and major sources of pollution 

 are shown by arrows with numbers keyed to 

 Tables 7 and 8. Only estuaries that are af- 

 fected by pollution are named. They total 20 

 of the 40 estuarine study areas listed previously. 

 Their combined area is 31 percent of the area 

 of all west coast estuaries (Table 1) , but if Flor- 

 ida Bay is excluded from consideration because 

 most of it lies in Everglades National Park, their 

 combined area is 43 percent of the total. Ten
