12. Although terrestrial sources of potentially usable beach fill 

 exist, this report is limited to consideration of subaqueous sources because 

 these deposits are usually more desirable as borrow sources for economic and 

 environmental reasons. However, subaqueous borrow source investigations are 

 much more difficult and expensive, and improvements in technology and tech- 

 niques can result in a significant reduction in costs. 



13. The focus of this report is on the state of the art of borrow 

 source exploration in terms of the basic items of equipment presently avail- 

 able for the conduct of a borrow source exploration program and how they can 

 be used to gather necessary information for locating and characterizing poten- 

 tial borrow sources.
