realistic evaluation procedures in this difficult area will require 

 generations of research, recognition of marginal concepts and 

 extra market utility in the context of risk and uncertainty would 

 be of immense value to management policy and program formulation. 



Pollution Control 



In the specific area of water pollution control, studies should 

 be made on the development of a better information system on the 

 capitalization of in-place pollution abatement facilities. Ade- 

 quate reporting of investment data exists only for the period from 

 1952 to the present, and there is little in the way of reliable 

 depreciation information relating to sewers and wastes treatment 

 facilities. Development of historical investment and depreciation 

 levels would be useful in the development of national investment 

 policies informed by an adequate awareness of capital requirements. 



There is a requirement for research into the effectiveness of the 

 various pollution abatement strategies. Comparative evaluation 

 of results of the several program emphases, i.e., various control- 

 ling jurisdictions, consequences in terms of financial outlays, 

 water quality preservation or degradation, water utilization con- 

 straints, would be useful in forming least cost national and 

 state-controlled programs in the future.
