The average hydraulic conductivity of the Empress Gravels is some five 

 orders of magnitude higher than that of the tills. The volume of water 

 flowing through the Empress Gravels would therefore, under similar head 

 conditions be correspondingly much higher than the volume of leakage from 

 the overlying tills into the gravels. Because of this, the dilution 

 effect would be large enough so as to mask or otherwise render 

 Indeterminable the effects of increased leakage, on the water quality. of 

 the gravels.

Water quality samples for wells 2 through 11 were collected in August, 

 1985. No significant changes in water chemistry have been observed. 

 After additional development on wells 13 through 19, 21 and 22 (by 

 bailings), samples were collected from wells 13, 14, 15, 17, 18, 19, 21 

 and 22.
