DISPOSAL IN SEDIMENTS 
Containing Packaged Wastes in the Sea Bottom. 
There exists the possibility of using sediments on the sea 
floor as an enveloping medium. If engineering progresses so that 
waste volumes may be economically concentrated, the sea bottom becomes 
a logical place for disposal. On the bottom the wastes may in time 
be covered with sediments with reduced possibility of dispersal. 
A suitable container of reasonable size to carry the concentrated 
wastes down might be 2 feet in diameter by 20 to 30 feet long with 
a mean density of 3 or 4. The container should sink through the 
water with a velocity of at least 60 knots; with a carefully selected 
bottom it might penetrate one “anode. A proper location would be R 
in a basin having active deposition which would cover the ceeieeals 
In reviewing the idea of disposal in the bottom with geologists 
it was learned that, generally, they are not too sanguine on the 
penetration theory but were quite hopeful on the possibility of 
areas with rapid deposition. Unfortunately none of those areas of 
deposition are close to existing waste producing plants, Transportation 
(27) 
and cost of transportation are matters of no small concern, 
Natural Adsorption on Sediments. 
There are natural processes occurring at river mouths which 
remove from water many of the elements in the fission product range. 
If this adsorption did not occur, many of the elements present in 
sea water in trace quantities would be present in much larger amounts. 
Because of the possible deleterious effects on sea life along the
