Saskatchewan Power continues to esqjeriment with the surcharging of 

 dry ash into the lagoons . An experimental program began in 1987 to 

 determine suitable types of vegetation for the exposed ash. Two 

 species of grass showed some promise for this purpose. Further 

 testing will continue in 1988. 



Saskatchewan Power has, since Hay, 1983, undertaken analyses on 

 filtered ash lagoon water samples to obtain appropriate information 

 on potential leachate quality. Generally, the water quality data 

 show increases in the Ash and Polishing Lagoons for sodium, 

 potasium, sulphate, fluoride, boron and molybdenum; and continued 

 variability in the levels for uranium, and vanadium. In addition, 

 there were some decreases noted for other measured variables such 

 as strontium and chromium. The changes are to be expected in a 

 closed system of this type.
