Related to this is research into the influence of water availa- 

 bility and public-policy regarding water use and pollution control 

 on industrial location decisions. There is evidence that separate 

 industrial categories are affected by and react to a single set 

 of water conditions in different fashions, but no comprehensive 

 survey of response to conditions has been conducted at this time. 



There are a large number of conditions where controls must be 

 developed to deal with diffuse poTlutional influences of natural 

 runoff (siltation, water-borne pesticides, concentrated urban 

 runoff, etc.) and where costs have been inadequately examined or 

 are unknown. Such cost data are essential to formulation of 

 meaningful abatement programs and their development should provide 

 a number of research projects. In general, however, these kinds 

 of information requirements cannot be satisfied by economists 

 alone, since they require technical determinations demanding 

 the skill of hydrologists, biologists, engineers, and others. 



Economic Planning Units 



One of the most immediate needs is for the delineation of suitable 

 economic planning units for comprehensive estuarine management. 

 What is the minimum area of the estuarine resource that must be 

 incorporated into a system before it can be managed effectively? 

 If suitable economic planning units can be delineated and the
