Frequently Asked Questions
Will this project risk contamination of drinking water? No.
1. This is non-hazardous material that is currently approved for application
directly on the land surface. Placing material 5000 ft below ground is
inherently more protective of surface and groundwater than placing it
on the surface.
2. The heat in the subsurface provides almost immediate sterilization.
3. Geologic setting (impermeable confining layers), well design (multiple
casings), and continuous monitoring practices will ensure confinement in
target intervals.
4. Finally, we have chosen an isolated, offshore fault block for the field
experiment.
Will this project cause an earthquake? No.
1. Planned injection represents less than 3% of current injection taking
place in the Wilmington Field;
2. Past injection has been extensively monitored by City of Long Beach and
Southern California Earthquake Center for more than 20 years with no
activity other than natural seismicity in area;
3. Injection interval is soft, aseismic, and relatively shallow (earthquakes in
LA Basin generally are deeper than 20,000ft);
4. Average formation pressure will not be significantly elevated.
Will this project increase air pollution? No. Quite the opposite!
1. More than 50 trucks per day currently load and transport LA City
biosolids for land application more than 100 miles from the City. Truck
traffic and associated emissions will be significantly reduced by this
project.2. Project will eliminate significant CO2 emissions into atmosphere.
Will this project really save energy? Yes!
1. Project will reduce energy required to transport biosolids.
2. Project will reduce energy required to de-water biosolids.
3. Project will reduce energy required to thermally treat biosolids to Class A
standards.
4. Some methane may be recovered for fuel cell use at sanitation plant
providing a potential source of renewable energy.
Why evaluate this technology? The status-quo is not good enough and is not sustainable!
If demonstrated successful, this technology will:
1. Improve environmental protection of surface and groundwater.
2. Reduce air pollution and greenhouse gas emissions.
3. Provide energy savings.
4. Allow large urban centers to responsibly manage their biosolids, locally
and more cost- effective, while at the same time reducing their impact
on the environment
