Abstract:During the past two decades in Hawaii, more than 500 injection
wells for the disposal of domestic sewage wastewater have been constructed and
operated. Thus far, contamination of potable groundwater supplies has not been
a problem. Many of the injection wells, however, have not performed as designed
, and aquifer clogging and reduced injection capacity have produced
numerous well failures resulting in public health, legal, and financial problems.
Factors most commonly responsible for the well problems have been unfavorable
hydrogeology, underdesign of injection well capacity, poor effluent quality, and
lack of injection well maintenance. Detailed study of clogging mechanisms in the
immediate vicinity of injection wells suggests that binding of pore spaces by
nitrogen gas is the most important cause of aquifer clogging. Other clogging
mechanisms also operating are filtration of solid particles and growth of
