Sirs:

I have just read your e-mail about the former Naval Air Station at
Alameda and the soil and groundwater contamination at this site.

Our company has been developing remediation technology involving the use 
of directionally -drilled horizontal wells to perform soil and
groundwater remediation.  A major benefit of this technology is that
large areas can be treated using just a few wells.  Moreover, the
treatment equipment associated with each well can be placed in areas of
the site which do not interfere with surface operations.  Lastly, these
wells can be placed under buildings, paved areas, and other facilities
without adverse impacts.

For petroleum sites, especially, we have found that using these wells to 
perform in situ biodegradation is particulary cost-effective.  All that 
is necessary to to blow air through the contaminated area. 
Naturally-occurring microbes will biodegrade site contaminants.  

For sites such as NAS Alameda, directionally-drilled biosparge wells can 
be placed near the down-gradient edge of contamination plumes and
positioned in such a way that on-site contaminants cannot and do not
migrate to off-site receptors.  We have cleaned up air ports, petroleum
terminals, refineries and other facilities using this approach. 
Currently, we are using the same approach to address chlorinated solvent 
contamination at two DOE sites.

In my view, the Navy and other DOD installations could well benefit from 
this technology and our experience.  Horizontal biosparge wells commonly 
cleanup sites at a cost of only about 20% of traditional vertical well 
pump-and-treat approaches.  They are also better than monitored natural 
attenuation since they will produce a clean site in our lifetimes.
