Investigation and Remediation
of Contaminated Soil and Groundwater
Over the past 15 years, RBDI has successfully
obtained No Further Action letters
from regulatory agencies on 23 chlorinated solvent
sites and an additional 42 sites impacted by MTBE/gasoline,
pesticides, PCBs, dioxins, or metals.
Among these was closure of a Superfund site
impacted by chlorinated solvents, where our client
was released from the PRP group as a result of our
analysis.
The
following key factors distinguish RBDI from others
in the field:
 |
Perform statistically valid soil and groundwater sampling such that each
sample collected can be justified on a scientific basis minimizing the
need for multiple rounds of sampling and associated cost excursions.
|
|
|
Developed techniques to chemically “fingerprint”
contaminant
sources in both soils and
groundwater
(Jamall, I.S., Lu, T.X., Huber,
W.A.
2005.

Chlorinated Solvent
Plumes: A Comprehensive

Implemented innovative methods to remediate chlorinated solvents
in situ in record time and at a fraction of the cost of
pump-and-treat.
|
|
|
Developed
in situ oxidation techniques to treat
carcinogenic pesticides previously believed to
be recalcitrant (Jamall, I.S. and Brown, I.
2006.

in Wastewater.

Environ. Contam. Toxicol. 76:740-744)
|

|
Developed, designed, and implemented an
ex
situ UV/peroxide
treatment system to
destroy MTBE in extracted groundwater by as
much as 98%, thereby significantly extending
the life of the activated
carbon units
from change-outs every 7 weeks to no
change-outs for
765 days resulting in
substantial cost savings to the client
(Jamall, I.S., Lu, T.X. and Powers, J.
2006.
