| WEST HIGHWAY 6 & HIGHWAY 281 | Hastings, Nebraska | |
| Adams County | 3rd Congressional District |
Site Location/Size:
The West Highway 6 & Highway 281 site is located in Hastings, Nebraska,
in Adams County. The area of soil and ground water contamination is
approximately 1.75 miles long by 1/3 mile wide.
Site History:
One known source of the ground water contamination appears to be from
the former Dana Corporation facility, which manufactured a variety of
cast piston rings for internal combustion engines at the Hastings
facility. The former Dana facility housed four vapor degreasing units
inside concrete pits that utilized tetrachloroethylene (PCE) and
trichloroethene (TCE) as degreasers to clean the piston rings during wet
machining operations. The vapor degreasing units were used from the
1970s through the 1990s. A release of solvents occurred approximately
between 1984 and 1987, but the amount of PCE released is unknown. PCE
contamination was first documented at the facility in 1998 during a
Phase 1 and Phase II Environment Site Assessment. As a follow-up, Dana
hired a consultant to conduct a soil and ground water subsurface
investigation at the facility in 1999. Dana has since ceased operations
at the facility, and the facility is currently owned by another company.
EPA is investigating other potential source areas in the surrounding
area.
Site Contamination/Contaminants:
During sampling investigations, elevated levels of PCE, TCE, vinyl
chloride, carbon tetrachloride, and other volatile organic compounds
were present in the primary drinking water aquifer within the study
area. Two municipal wells and several private wells contained PCE at
levels above the maximum contaminant level.
Potential Impacts on Surrounding Community/Environment:
The City of Hastings consists of approximately 24,064 people consuming
drinking water from a municipal system. The ground water plume of
contamination has impacted two municipal wells and several
privately-owned domestic wells.
Response Activities (to date):
Dana Corporation performed multiple response actions at the source area
under the State of Nebraska's Voluntary Cleanup program. Dana
Corporation conducted installation of soil vapor extraction and ground
water extraction systems and permanganate injection in affected onsite
portions of the aquifer. Ground water sampling conducted by Dana in
January 2005 indicated very high levels of PCE remain in the aquifer
beneath the site. Three private wells have been impacted by the
contamination and the users of these wells have recently been connected
to the municipal water supply.
