- Geologic
conditions
- Hydrogeologic
conditions
- Depth
to the water table and seasonal water level fluctuations
- Directions
of flow paths and groundwater velocity between the injection
and monitoring wells (tracer test, etc.)
- Zones
of preferential flow
- Depth
of drilling to minimize the cost
- Other
contaminants and geochemical conditions
- Be
sure that the zones of influence of the injection and monitoring
wells intersect each other
- Consider
alternative methods for HRC injection
- Linear
source
- injection
through the trench
- injection
through a horizontal well
- Areal
(spatially distributed or discrete intervals) injection
- Consider
an option of groundwater pumping through a monitoring well
- HRC
injection
- Changes
the formation permeability
- HRC
solubility and the diffusion coefficient in groundwater from
Hanford
- The
zone of influence of HRC in the formation
- A
preliminary bench-scale and small-scale field injection test
- Using
geophysics to control the zone of HRC distribution in the formation
during injection and its degradation over time
