PROBLEMS FROM DEVELOPMENT 141 



ground water than is presently pumped, with full replenish- 

 ment from the streams. Hydrologic data are needed to show 

 the most promising areas for additional development and 

 also the most economical corrective measures for the con- 

 ditions that have developed in the heavily pumped areas. 



Louisville, Ky. 65 Here the wartime shortage of ground 

 water was acute. Some wells dropped far below the yield re- 

 quired of them, and it was obvious that pumpage of 63 mil- 

 lion gallons a day took water from the well fields faster than 

 it could be replaced by precipitation and the Ohio River. 

 The industries dependent upon ground water took prompt 

 action to prevent further depletion of the well fields, by 

 reducing pumpage to 40 million gallons a day (conserva- 

 tion and reuse of water helped) and recharging the wells 

 during the following winter with w r ater pumped from the 

 Ohio River by the city of Louisville. Since the war, pumpage 

 has dropped to 30 million gallons a day; the water table is 

 rising slowly in the industrial area but still dropping about 

 2 feet a year in the downtown area because of pumping for 

 air conditioning. Since the war, too, hydrologic studies have 

 shown that more than 250 million gallons a day can be de- 

 veloped by wells along a 7-mile reach of the Ohio River 

 northeast of Louisville, and about 50 million gallons a day 

 can be developed southwest of the city. To develop this 

 water by infiltration, the wells must be spaced scientifically 

 along the riverbank, not clustered to conform to the density 

 of population or industry.
