 Atlantic rem'on. Some industrial development in other reaions tends 

 to follow historical or oresent raw material availability. Leather 

 product Dlants are clustered in the North Atlantic reoion, and lum- 

 ber manufacturinn plants ere most plentiful in the Pacific Northwest. 

 Food processing plants, however, follow closely the distribution of 

 Donulation. 



While much of the industrial development located in coastal counties 

 affects the estuarine zone indirectly throuoh use of adjacent land, 

 some of the water-usinn industries have an impact on the estuarine 

 zone far beyond their numbers. The naner, chemical, petroleum, and 

 primary metals industries are the ma.ior water us^rs -mono manufactu-
