New Fact Sheet on Cleanup Activities at Metachem
Available; See the Metachem Link on DNREC Website: www.dnrec.state.de.us
The Delaware Department of Natural Resources and Environmental Control
and the U.S. Environmental Protection Agency have released an eleventh fact
sheet on the cleanup operations at Metachem Products LLC.
The Fact Sheet provides the public with an update of recent design
activities for the soil/sediment and groundwater cleanup and the
chlorobenzene removal and separation project operations.
Additional soil and data sampling results from the 2003 study show that the
chlorinated benzene compound contamination in the soil piles and upland
areas around the facility has not spread to adjacent areas since 1993;
however, the study concludes that since 1993, contamination in nearby
wetlands has spread downward and laterally in the sediments.
This new area of contamination does not pose any additional impacts to human
health. EPA is studying the feasibility of using in-situ chemical oxidation
at the site. This technology involves injection of oxidants just below
ground level to break down and clean up the contamination.
Groundwater testing data during the last several months show the groundwater
plume is stable and not expanding in the Columbia aquifer system and that
the Potomac aquifer remains unaffected. Groundwater samples from Columbia
aquifer wells, located across Red Lion Creek and across the tributary west
of the site also show no contamination.
The chlorobenzene removal and separation program began 24 hours per day,
seven days per week July 17, 2003. As of Aug. 27, 2003 over 675,000 gallons
of chlorinated benzene compound mixture has been separated into two separate
chlorobenzene mixtures and solidified. The operation continues to separate
nearly 10,000 pounds of mixture per hour and is expected to continue for the
next six months.
The fact sheet can be obtained in several ways. It is available on DNREC's
web site at www.dnrec.state.de.us by clicking on the "Metachem Cleanup" link
on the front page. DNREC has also set up a listserv so that those interested
can have the fact sheets electronically mailed to them. To sign up, go to
www.dnrec.state.de.us/dnrec2000/ and select "DNREC Direct." Check "DNREC
Metachem List" and then select "Join Checked Lists." For those without
access to a computer, you may request that a copy of each fact sheet be
mailed to you by calling Gayle Govorko at (302) 739-4764 and signing up for
the Metachem mailing list.
In addition to DNREC's web site mentioned above, EPA has also established a
web site: www.epaosc.net/Metachem. There is also a hot link to this site
from DNREC's site. EPA's web site includes pictures of major activities that
have occurred each week since Metachem announced the plant's closure along
with weekly status reports of site activities.
