| Project
Navigator has been managing large complex groundwater
problems at major sites since the company's founding in
1997. Our approach is to blend sound science with strategic
thinking to derive the most cost-effective, robust and
simple solution to the problem. We focus on what is defined
as compliance, which remedial components will best achieve
compliance, and the possible timeframes required. We pay
special attention to forecasting what might be the O&M
timeframe, for experience shows that a large fraction
of a remedy's NPV is in O&M costs. |

| Projects
where we have made a significant impact on groundwater
activities on behalf of our PRP clients include: |
| |
- At
the OII
Landfill, Ian Webster was president of
New Cure from 1997 to 2000. While the main focus of
his work was on the gas and cover remedy, he also
oversaw the ongoing groundwater RI/FS.
|
- At
the Tex Tin Superfund Site in U.S.
EPA's Region 6, PNL is the project coordinator. We
have managed the entire project for the Tex Tin Steering
Committee from assessment, through design/build and
now into O&M. The goal of the work was to redirect
shallow impacted groundwater via slurry walls and
manage the plume at the downgradient end of the site.
|
- At
the MAR Services Site in Louisiana,
PNL has worked with the major oil company project
owners to structure a cost-effective remedy where
the groundwater component is natural attenuation and
monitoring.
|
- Project
Navigator was the project coordinator at the El
Monte Operable Unit from 2000 to 2003.
We assisted the PRPs negotiate an SOW with EPA and
plan a compliance monitoring program.
|
- Project
Navigator has assisted a confidential client make
sense of an enormous groundwater database for a local
project. We have plotted all data in 3D using GIS.
The resulting simulations have allowed our client
to develop a project strategy.

|
| Additional
examples of Project Navigator Groundwater Experience: |
| |
- Project
Navigator managed the groundwater assessment at the
Waste
Disposal, Inc. Superfund Site, and was
the lead advocate for the PRPs with EPA on selecting
the Monitoring Only remedial alternative.
|
- Project
Navigator is managing the groundwater RI/FS at the
Ascon
Landfill Site in Huntington Beach. In
2001 we performed a focused study at the site by installing
hydropunches to quickly and cost-effectively derive
a snapshot of the site's groundwater conditions. This
snapshot has been used to guide the ongoing 2004 RI/FS.
|
- At
the PAB Oil and Chemical Superfund Site
in Louisiana, PNL has managed EPA negotiations, design
and construction work on a source treatment and control
remedy. The groundwater is currently being monitored
by PNL via an appropriately sized monitoring well
network.
|
- We
have also performed conceptual design and project
cost analysis for a major oil company at a site impacted
with salt water in Florida.
