Effectiveness of a grout curtain to prevent seepage into ground water. It was doubted by the engineering geologists present Mat any grout curtain is 100 percent effective.

. What would be needed would be a test of the pit with tracers, over a period clef time equivalent to the length of storage time.

From page 94... ...
These sites appear to have all the disadvantages of granite quarries ~ a magnified form . It would be virtually impossible to seal them so that liquid waste s would not contaminate groom water supplie s .

If the material is placed in shale pits, deposition of solids will occur at the bottom and produce seating there. The clear supernatant with some high radioactivity ~11 pass out the sides.

Is there a geologist present who knows of a clay deposit ten feet thick, without bedclirlg plies and fractures? (No volunteer s ~ In propane storage we can take a slight i088 but here we're taming about zero leakage.

Chairman: Infiltration of material close to the surface into permeable Ed semipermeable formations: A good estimate of adsorption capacitie s word be twenty tons of clay for complete adsorption of one thousand gallons. How much clay is there in the desert basins ?

b. The f~giomerate at the edge calf a desert mountain range Louis be a suitable test site, if preliminary laboratory te sts are favorable .

From page 99... ...
A deep dry mine (not on a fissure rein deposit) Would definitely be suitable for storage of ctry wastes in containers and might be suitable for liquid wastes.

From page 100... ...
Solution cavities In salt are probably the most promising sites for relatively shallow ;lisposal of liquid wastes. Both bedded salt any salt domes are pos Bible, although bedded salt would have more prob lems, such as the greater difficulty of controlling the size and shape of the cavity and the additional testing of the roof and floor rocks.

From page 101... ...
Solution caviled ~ mat domes are probably She best potential Bites for the disposal of liquid wastes at shallow depths. Caprices ~ salt beds are also good potential sites, but must be viewed with more caution.
|
From page 102... ...
Salt domes can be written off as economically worthless because of huge arnour~ts of salt available. Salt has twice tide heat conductivity of soil, ~d a melting pout of 800° C

From page 103... ...
Some may be fifteen thousand feet thick, or more. Consensus: Salt storage is a preferred method for liquid disposal.
