Subsurface Waste Disposal by Injection in Hawaii: A Conceptual Formulation and Physical Modeling Plan

November 1974
ABSTRACT
Emphasis on water pollution control and stringent regulations on waste water disposal into surface and coastal waters has focused attention on subsurface disposal as an alternative of great promise for increasing use in Hawaii. However, the need exists to ascertain the mechanics of injection well systems and the fate and effects of the injected fluid in the aquifer. A laboratory study was begun to examine the hydromechanics of waste injection into Hawaiian density stratified groundwater systems using both a sandbox model and a vertical Hele-Shaw model. The sandbox model is constructed to allow use of a variety of aquifer fluids and movement of dyed injection fluids will be followed by visual observation, liquid sampling, and photography. Both models are nearly completed and ready for preliminary testing and experimentation.
