| PARKVIEW WELL | Grand Island, Nebraska | |
| Hall County | 3rd Congressional District |
Site Location/Size:
The Parkview Well area is located near the southwest corner of the City
of Grand Island, Hall County, Nebraska. Investigations in this area
identified two contaminant plumes: the northern plume extends from the
Case New Holland (CNH, an agricultural combine manufacturer) property
east toward the Parkview subdivision, and the southern plume extends
from a golf course west of the Marylane, Kentish Hills, and Castle
Estates subdivisions to the east where it commingles with the northern
plume under the Parkview subdivision.
Site History:
Beginning in 1965, CNH has primarily manufactured and assembled
agricultural combines. From 1966 to 1975, CNH dumped paint sludge, spent
solvents, waste oil, waste machine coolants and other waste material in
the burn area on the property. From 1975 to 1980, plant operations
included burying both containerized and noncontainerized paint sludge,
spent solvents, waste oil, waste machine coolants, and other liquid and
semiliquid waste in the burial area. In 1991, CNH contractors identified
burn and burial areas in the southern portion of CNH impacted by past
waste disposal practices at the property.
Routine monitoring first detected volatile organic compounds (VOCs) in a
nearby municipal well in 1999. In 2001, the contamination in the public
well exceeded health-based benchmarks and the City found contamination
in numerous private wells around the Parkview subdivision. A few of
those private wells showed contamination exceeding EPA's Maximum
Contaminant Level (MCL). In 2002, CNH investigated its property and
found significantly elevated levels of VOCs in soil and ground water.
Additional sampling in 2003 by the Nebraska Department of Environmental
Quality and the City found many more private drinking water wells with
contamination exceeding MCLs.
Site Contamination/Contaminants:
The main contaminants of concern are VOCs, specifically
1,1-dichloroethylene (1,1-DCE) and tetrachloroethylene (PCE).
Potential Impacts on Surrounding Community/Environment:
Seventy-four private drinking water wells and one municipal well contain
ground water contaminated with VOCs at levels exceeding health-based
standards, impacting approximately 1,384 individuals. In addition, 69
private drinking water wells, which supply drinking water to
approximately 179 individuals, have been documented to contain VOCs at
significantly elevated levels.
Response Activities (to date):
On November 3, 2000, CNH entered into Nebraska Department of
Environmental Quality's (NDEQ) Remedial Action Plan Monitoring Act
program. Alternative water or filtration systems currently are being
provided to those whose drinking water is contaminated above action
levels.
