Hanover USDA Site
Site Background
The KDHE-Bureau of Environmental Remediation (KDHE-BER)
is overseeing an environmental investigation being conducted at the
former Commodity Credit Corporation/U. S. Department of Agriculture
(CCC/USDA) facility in Hanover. The investigation is being conducted
by Argonne National Laboratory on behalf of the CCC/USDA.
Carbon tetrachloride, a grain fumigant used at the
Hanover facility, has been detected in the groundwater and soil beneath
the former CCC/USDA facility. The contaminant was also detected in indoor
air samples collected at several homes built on the former facility.
KDHE has completed a study of mortality rates for Hanover, Kansas,
for the years 1999 to 2007. The purpose of the study is to provide information to Hanover
residents who may be concerned about the overall health of the community, in light of
the ongoing environmental investigation at the former CCC/USDA facility. The report
indicates that, after adjusting for age, the mortality rate in Hanover is similar to
the mortality rate for the entire state of Kansas. The study may be viewed or downloaded

In August 2009 indoor air samples were collected from
several homes where trace levels of contaminants had been previously
detected. The purpose of the sampling/monitoring event was to provide
information/data to better determine if vapor intrusion is a concern.
Additionally, CCC/USDA installed three vapor intrusion mitigation systems
in homes with confirmed problems of indoor air vapor intrusion.
Recent field work events included the installation of
additional monitoring wells. More work is being planned that will provide
information on aquifer characteristics. KDHE-BER will continue to work
closely with CCC/USDA to complete the investigation and determine the best
means to address the contamination.
