Fact Sheet
September 2006
Remedial Action Implementation - Ogallala Ground Water Superfund Site OU2, Ogallala, Nebraska
INTRODUCTION
The U.S. Environmental Protection Agency (EPA) will be initiating the implementation
of the remedial action at the Ogallala Ground Water Superfund Site known
as Operable Unit (OU) 2. The activities will involve the placement
of a chemical oxidant that would further degrade and reduce the levels of
contamination in the ground water. The first injection event is tentatively
scheduled for the week of September 11, 2006, to be followed by subsequent
injections every 3 months.
ABOUT THE CONTAMINATION
Perchloroethylene/tetrachloroethylene (PCE) is the contaminant of concern at the OU2 portion of the site. PCE is a chlorinated hydrocarbon solvent. PCE is commonly used in dry-cleaning fluid, spot removers, and degreasers.
BACKGROUND
The Nebraska Department of Health discovered contamination in Ogallala's water supply wells during routine sampling in 1989. Since that time, the City has installed a new well field. The Ogallala Ground Water site was placed on the National Priorities List in December 1994, making it eligible for cleanup under EPA's Superfund program. Several actions have already been taken to address contamination at other parts of the site.
On February 3, 2006, EPA issued a Record of Decision for OU2 of the site. In the ROD, EPA presented the selected remedy to address the contamination in the ground water. The remediation goal of this remedy is to reduce contamination in the ground water to below drinking water standards.
EPA and its contractors will be performing the prescribed work at various locations extending from West A Street to East F Street.
