Geoloqical Survey and by the Federal Water Pollution Control 

 Administration. It is among States, university groups, and 

 Federal grant program receivers that most of the identification 

 work should be concentrated. 



5. Existing similar data systems should be used reciprocally 

 and cooperatively to store and retrieve various data types. 

 These systems include the Inventory, STORET, USGS Hydrologic, 

 and NODC. The compatibility of system concept and structure 



of these four systems is such that they can function as comple- 

 mentary segments of a single large storage and retrieval system. 



In data gathering, for example, each organization searches pri- 

 marily for the type of data which its "software" (that is, 

 programs — the machines themselves are "hardware") will accept. 

 It is inevitable that the searches will encounter information 

 which can be stored in a sister system more efficiently; thus, 

 a considerable amount of duplication can he saved. 



6. Concurrently with data gathering, processing and servicina, 

 there must be a constant background of analytical data information 

 investigation to identify special needs and conditions, and to 

 explore new possibilities and applications, both directly and 



by contract.
