                           Companies Agree  to Address
                           Vapors and  Contamination
                                  Hartford Area Hydrocarbon Plume Site
                                  Hartford, Illinois
                                                                           March 2004
                           Three oil companies have agreed to study ways to permanently clean up a
                           large pool of refined petroleum products that has contaminated the ground
                           underneath much of northern Hartford. The companies have also agreed to
                           find ways to protect homes and other buildings from dangerous fumes while
                           they design a permanent cleanup.
                           On March 17, U.S. Environmental Protection Agency signed a legal
                           agreement with Atlantic Richfield Co., Shell Oil Products US,  and Premcor
                           Refining Group. These companies are considered potentially responsible
                           for the contamination. In this legally enforceable settlement, the companies
                           agreed to complete a thorough investigation of the pollution by the end of
                           2004 under EPA supervision. Once the investigation is complete, the
                           companies will design a way to permanently clean up the contamination in
                           the ground with the oversight of EPA.
If you suspect vapors in your home...
If you smell or suspect you have fumes in your home:
Call the Hartford Fire Department by dialing 911.
As part of the agreement signed by the companies, EPA has required they
develop a plan for responding to complaints of vapors in homes. The
companies have agreed to provide temporary housing and money for
incidental expenses if residents need to be evacuated from their home. EPA
will notify residents of further details of this plan once they are available.
                           Two kinds of home vapor removal systems being studied
                           Until the contamination can be removed, the companies have agreed to find
                           ways to protect people from possible vapor exposure in their homes. At
                           the end of February, a study was started to see if fumes can effectively be
                           stopped from getting into
                           houses. The study is              ' EXHAUST
                           being done at two
                           residences in north
                           Hartford.
                                                 VENT PIPE
                           At one home, a pipe was
                           put into a small hole drilled
                           in the basement floor and
                           was routed through the
                           wall and up the side of the
                           house to the roof. A fan
                           draws the vapors up
                           through the pipe. The
                           sketch to the right shows
                           how this system works.
                        FAN
                      This drawing shows the type of vapor removal system
                      installed in a basement.

-------
The second system is
similar. The vapors are
drawn up through pipes
placed at four spots
outside the home. These
four pipes—all of which
are underground—are
linked by another
underground pipe that
encircles the home and
comes out of the ground
along the side of the
home, reaching to the
roof. A fan draws the vapors into this vent pipe expelling
them at roof level as in the diagram on Page 1.
This photo shows what a vent pipe
might look like at a home with a
vapor extraction system installed.
Once this study is complete, EPA will determine if either
of these systems will work in homes where vapors are a
problem. This study is expected to be completed by
May 1. However, if EPA determines that these systems
are not working, it will require the companies to find
other ways to protect people from dangerous fumes.

Investigating other ways vapors get into
homes
Another study the companies will be doing is looking at
other ways—such as through the sewer lines—that
vapors may be getting into houses. EPA expects a report
on the results of this investigation by June 2004.

1990s vapor removal system also studied
The companies are currently evaluating the effectiveness
of a system of extraction wells (put in to remove the
vapors) that were installed in the 1990s. Those wells
allow vapors to rise from the soil through pipes. The
vapors are collected and sent to be treated on the
Premcor property.  The treated air is then released. If
EPA finds that all or some of these wells are still in good
shape and are in good locations, they may be used for a
new vapor removal system. The companies, at the
request of EPA, have installed a newer type of vapor
extraction well and are testing it to see how effectively it
works. (See map on Page 3 for the locations of the
vapor extraction wells.) The treatment system on the
Premcor property is also being examined for its
effectiveness. Although still operating, the wells and
treatment system installed in the 1990s are not as
effective now as they once were.
Protecting the water supply
Five monitoring wells have been installed between the area
affected by the contamination and where the village water
wells are located. These "sentinel" wells are being
monitored to ensure that the underground contamination
does not reach the village water supply. The results of the
samples taken from the sentinel wells so far have shown
no contamination. The map on Page 3 shows the
locations of these wells.

Designing a permanent cleanup
In the legal agreement, the companies potentially
responsible for the contamination have agreed to design a
long-term solution. The specifics of the cleanup will
depend on the investigations that are under way.
As part of these investigations, the companies pushed an
instrument into the ground at 66 different locations to find
out if petroleum products exist at each of those locations.
(See map on Page 3.) The technicians used a Rapid
Optical Screening Tool, which uses a laser to detect a
petroleum product. When the laser is pointed at a
petroleum product in the ground, it reflects fluorescent
light, confirming its presence.

                             Soil samples were also taken at 12 of the locations to help
                             EPA confirm the results of the optical screening. (See
                             map on Page 3.) This investigation, including the optical
                             screening and the soil sampling, will help EPA determine
                             where and how widespread the contamination is. This will
                             help the companies and EPA determine the best way to
                             design a permanent cleanup.

                             Pumping out the petroleum products
                             The companies are also studying how to pump the
                             petroleum products out of the ground. Two of three
                             existing wells are being used to see how quickly the
                             pollution can be removed. (See map on Page 3.)
