permit evaluation of wind, river inflow, tide, and internal 

 waves as transport mechanisms. 



(2) To improve our ability to predict the fate of pollutants 

 introduced into estuaries and coastal waters under specific 

 environmental conditions, a study is recommended of the 

 effects of intermediate scale variations in the current 

 pattern on the time varying concentrations of waste compenents 

 at various distances from the source, using tracers such as 

 fluorescent dyes as well as waste components from existing 

 outfalls. 



(3) It is recommended that the large-scale processes which 

 lead to exchange of coastal water with oceanic water be 

 studied. One possibility is the development of a fluorometer 

 capable of sampling at all depths which is an order of 

 magnitude more sensitive than at present so that large-scale 

 dye tracer experiments could be carried out economically. 

 Another possibility is a search for a more economical tracer. 



Decay of Non-Conservative Constituents 

 as Related to Physical Factors 



A series of controlled field experiments should be conducted to study 

 the non-conservative properties of such constituents of wastewater as 

 enteric bacteria and other toxic substances discharged into coastal 

 and estuarine waters. As soon as reliable detection and enumeration
