PROBLEMS FROM DEVELOPMENT 113 



from those recharge areas, for distances as great as 7 miles 

 in the case of Ivorydale. 



Water spreading in recharge areas north of the clay cap 

 would probably increase the supplies for Wyoming and 

 Lockland, which are only a mile or two to the south. For 

 Carthage and Ivorydale to be benefited by such a program 

 would take years, plus a guarantee that Wyoming would not 

 take the water as it goes by. All other corrective measures 

 depend upon bringing water into the area from more ade- 

 quate sources outside the valley. This was done successfully 

 in 1943 for the war-emergency plant of Wright Aeronauti- 

 cal Corporation, built at Wyoming. When studies showed 

 that its water requirement of 8 million gallons a day could 

 not be met locally without aggravating a situation already 

 serious, a well field was developed along the watercourse of 

 the Miami River, and water was piped to the plant. Large 

 supplies could be similarly developed elsewhere along the 

 Miami or Little Miami Rivers, and brought in by pipeline. 

 As an alternative, the feasibility of obtaining Ohio River 

 water from the city of Cincinnati has been explored. Two 

 industrial plants are already purchasing water during the 

 winter when the temperature meets their needs and have 

 reduced their pumping correspondingly. 



It would be unfortunate if the ground-water reservoir in 

 lower Mill Creek Valley were marked off as useless because 

 it has not been adequate to meet demands to date. It is still 

 a place where a large volume of water can be stored, and if 

 the Ohio River (or other surface water) is eventually 

 selected to serve the water needs of Mill Creek Valley, the 

 industrial need for cool water would best be served by tak- 

 ing water from the stream in the winter, and storing it 

 underground for year-round use. 



Some areas of concentrated development are at no great 

 distance from the recharge area, measured in miles, but the 

 aquifers have been cut by barriers that prevent the free move- 

 ment of water into the area of development. Thus a wedge-
