suspensions and methods described herein the suspension should have a brookfield viscosity in the range of about 100 to about 2 000 centipoises preferably about 200 to about 1 000 cps more preferably about 200 cps to about 700 cps the uses for the powdered or granular material containing water submergible suspensions described herein are virtually infinite since the suspensions can be applied against very contoured and slopping surfaces rough or smooth into crevices in the waterway floor as well as below grades such as in tank farms and for irrigation and water conservation techniques the suspensions are substantially better than layered products having an intermediate layer of powdered or granular material since the suspensions will not peel apart and the contaminant reactant material is positioned easily over large areas without the tendency to leak out of the product as occurs with geosynthetic products during handling and installation the suspensions described herein have a number of other advantages over the prior art layered geosynthetic products that include an upper and lower fabric surrounding an interior layer of powdered or granular materials since the suspensions are relatively viscous liquids containing suspended solids the suspensions are particularly well suited for providing contaminant removal in shored wall conditions to protect surface areas that are either sloped or horizontal the suspensions are very durable since strength is not dependent upon any method of structurally securing two separate fabric layers together across an intermediate layer of powdered or granular material in another embodiment the suspensions described herein can be pumped in place under a geosynthetic fabric or film or large balloon type geosynthetic material fig5 that is disposed on a waterway floor underwater when disposed under a geosynthetic fabric or film which may be water permeable or water impermeable the geosynthetic.
