KURT MANUFACTURING COMPANY LANDFILL NATIONAL PRIORITIES LIST (NPL) SITE FRIDLEY, MINNESOTA FILE COPY DO NOT REMOVE APR I 0 1989 SUMMARY
The Kurt Manufacturing Cc:x!pmy National Priorities List (NPL) Site is
located in the City of Fridley, Minnesota. The site grourrlwater and soil
are contaminated with various volatile organic CCil1pClUIXls, primarily
tetrachloroethene, 1, 1, 1-trichloroethane, trichloroethene, and
1,2-dichloroethene. The extent of grourrlwater and soil contamination
appears to be limited to within the site boun:laries. The site surface
soils and subsurface soils are contaminated with low levels of
tetrachloroethene (8.6 Irgjkg, maximum and 100 rrgjkg, maximum,
respectively) and are not expected to pose a health concern. The on-site
grourrlwater is currently being use:i for Cc:x!pmy production process water.
It is not knc:mn if this water is use:i for pw:poses other than process
water. The ingestion and use of on-site grourrlwater without treatment
would pose a health concern. The inhalation of volatile CCil1pClUlXls from
the production process water would come urrler the authority of the
Occupational Safety and Health l\dministration (OOHA) which regulates the
worker envirorment. No data were provided for an evaluation of this
exp::>SUre pathway.
From an examination of the grourrlwater 100nitoring well
data, off-site private wells are not believed to have been affected by the
grourrlwater contamination. However, off-site wells have not been sanpled
and analyzed to confinn this conclusion.
A. SITE DESCRIPI'ION
The Kurt Manufacturing site is located in Anoka County, Minnesota (see
Apperrlix, Figure 1) approximately five miles north of Minneapolis. The
site is in an industrial setting and is bourrled to the north by another
establis!nnent, to the west by railroad tracks, to the east by Main Street,
and to the south by another building.
The Kurt Manufacturing Cc:x!pmy produces precision CC!l1p.lter components and
has been in operation since 1960. In February 1982, an investigation by
the Minnesota fullution Control Agency (~) indicated that two company
production wells were contaminated by volatile organic compounds (VOCs)
specifically, tetrachloroethene (K:E) , 1, 1, !-trichloroethane ('K:A) , and
1,2-dichloroethene (DCE).
In Decernber 1982, monitoring wells wells were installed at the site.
Results of the grourrlwater sanpling and analyses of these wells indicated
that the shallow grourrlwater near the Corrq:>any's loading dock was
contaminated by K:E.
Page 1
Until 1982, solvent-coated metal shavings frcan the machining area were
placed in a storage bin located near the loading dock. In October 1983,
high levels of PCE and TCA were fourrl in the soil and grounjwater near the
metal shavings bin sunp. MK:A and Corrpany representatives detennined from
the soil and grounjwater !IK)nitoring data that the metal shavings bin sump
was the source of grounjwater contamination by voes.
In April 1984, the MK:A issued a Request for Response Action to the
Company to complete a Remedial Irwestigation and Feasibility Study
(RI/FS).
In March 1984, the shaving bin
sunp was excavated and capped to prevent
further infiltration by this route.
'Ihe RI Final Report was completed on September 18, 1985, and the
Feasibility Study was completed on January 21, 1986.
13, 1986, a Minnesota Enforcement Decision Document (MEDD) approved
response actions that consisted of:
On May
1. lDng-tenn operation and maintenance of a contaminated grounjwater
pllJ1pOUt system to prevent migration of contaminated grounjwater by
punping to control the grounjwater gradient. 'Ihe pumped grounjwater
would be used in the manufacturing process, with the excess to be
discharged to the Metropolitan Waste Control Commission sanitary
sewer.
2. capping the sump area with an impervious material to minimize
infiltration through the remaining contaminated soil.
3. Abarrloning the shallCM production well to minimize migration of
contaminated grounjwater frcan the alluvitnll to the Prairie du allen
aquifer through the annular space along the well casing.
4. lDng-tenn !IK)nitoring to insure remedial action perfonnance.

A. SITE CliARACI'ERIZATION (DATA NEEDS AND EVAIIJATION)
1. Environmental Media:
Air: No ambient air monitoring data were provided for an evaluation.
Since surface soil concentrations of VOCs were very low, ambient air
contamination is not expected to be of concern. However, monitoring data
are needed to validate this conclusion.
SUrface water: SUrface water data were not provided for an evaluation.
Very little infoDnation was reported on surface water uses or surface
water impacts from the VOC contamination.
Little to no infoDnation were provided on lam use ani deiOOgraphics :fur
the site area. InfoDnation on the estimated population surrourrling the
site that would be useful in the Health Assessment pr=ess includes: the
nlll!lber of residences, locations of schools, hospitals, population
distribution by age, sex, scx::ioeconomic status, ethnic background, the.
occupations of employed persons, ani the lam use around the site.
3. Quality Control ani Quality Assurance (QlVQC):
'lhis Health Assessment was based on compiled data from the RJ!l.lEDIAL
INVESTIGATION, KURr MANUFACIURING o:::MPANY, DECEMBER 19, 1984, the RmEDIAL
INVESTIGATION, FINAL RER:lRr, KURr MANUFACIURING o:::MPANY, SEPI'EMBER 18,
1985, ani the FEASIBILITY S'IUDY, DErAilED ANALYSIS RER:lRr, KURr
MANUFACIURING o:::MPANY, JANUARY 21, 1986. ATSDR assumes that the sanplles
were haniled properly ani the analytical data provided by the laboratories
are correct. Insufficient infoDnation was provided on Qli,IQC to further
corrnuent on the validity of the data.
B: ENVlRONMENI'AL PA'IHWAYS
'lhe soil ani grourrlwater on the site are contaminated with varying
concentrations of voes. 'lhe voc indicator chemicals of concern are reE,
TCA, DCE, ani trichloroethene ('ICE).
On-site soil contamination of the surface soils consisted primarily oJf PCE
at relatively low concentrations (8.6 ngjkg, nrudnrum). PCE was founci at
Page 4
higher concentrations in soil samples taken greater than 6 feet belCM the
surface (100 rrgjkg, maximtnn).
'Ihe RI report noted that the shallCM groundwater flow across the site
appeared to be north to northeast. 'Ihe deeper groundwater flCM
corresporrls to the regional groundwater flCM, towards the Mississippi
River and to the southwest. 'Ihe glacial deposits on the site which house
an alluviumjdrift water table aquifer overlie the surface of the St. Peter
Sarrlstone, the first bedrock underlying the site. 'Ihe lower portion of
the St. Peter Sarrlstone deposit acts as a confining bed to the Prairie du
Chien fonnation, which is a carbonate bedrock aquifer for the area.
'Ihe soils and shallow groundwater beneath the Sl.ll!p pit were highly
contaminated with VOCs. 'Ihe RI report postulated that an a=idental spill
of waste solvents occurred at the Sl.ll!p pit. 'Ihe pit was excavated and
filled in March 1984.
'Ihe Kurt Manufacturing Conpany used a shallow and a deep production well
for water needs in the manufacturing process. 'Ihe shallow production well
was abandoned in 1986. 'Ihe shallow well was thought to be a factor in the
downward migration of contaminants by its punping activity. Contamination
of the deep production well was also thought to be caused by contaminant
migration via the annular space of the shallCM well. 'Ihe groundwater in
the upper levels of the drift aquifer appears to be moving in a northward
direction. After remedial activities had proceeded with the installation
of the J?Ul111;r0Ut system, the deeper groundwater appeared to be flowing in a
general northward direction across the site also.
Since the shallCM and deep groundwater contamination plumes do not appear
to have moved past the site botlrrlaries, dCMrJgradient potable supply wells
should not have been affected. HCMever, no infonnation was provided on
the location or the water quality of the dCMrJgradient private wells to
confinn this conclusion.
Although no infonnation was provided on VOCs exposure to biota, the
industrial, commercial nature of the site and surroundings would
discourage the raising of constnnable plants and anllnals.
C. HUMAN EXroSURE PA'IHWAYS
Incidental ingestion of contaminated soil by VOCs, inhalation of
contaminated fugitive dust, and dennal absorption of VOCs from soils are
possible human exposure pathways for this site. Incidental ingestion lli3.Y
occur during re!OOdial or construction activities, from smoking,
nail-biting, eating, etc. 'Ihe inhalation of contaminated fugitive dust
lli3.Y occur for employees during windy periods or for workers during
re!OOdial or construction activities if soil surfaces are disturbed.
IJennal absorption of contaminants lli3.Y occur when workers contact the
surface soils or subsoils during construction or re!OOdial work.
Page 5
.•.
VOC-contaminated groun:iwater ingestion, inhalation of VOCs released from
the groun:iwater, arrl dennal absorption of VOCs from groun:iwater would be
the most likely human exposure pathways associated with this site.
HCMever, it is not known if the water from the production wells were used
in the past for drinking water on the premises or were used for production
processes only. Agitation of the contaminated water, either during
production or use of the water for shCMering, bathing; etc., would release
voes. VOCs would then be available for human exposure by inhalation.
Dermal absorption of VOCs may cx:x::ur during shCMering, bathing, washing of
harrls, etc. 'lhere is no indication of exposure to site-related VOCs for
off-site users of the shallCM arrl deep groun:iwater; the shallCM arrl deep
contaminated groun:iwater pl1.I!reS do not appear to ext:errl beyond the site
boundaries.
'lhe possibilities of human exposure to VOCs by ambient air arrl surface
water contamination cannot be assessed because no data were provided on
these IOOdia.
Consumable plants arrl animals are not considered to be a human exposure
pathway of concern since the site is in an industrial/commercial setting.
RJBLIC HFAIJIH IMPLICATIONS
Although the possibility exists for human exposure to VOCs to cx:x::ur from
surface arrl subsurface soil exposure, the concentration of VOCs in the
soil is not high (PCE-100 rrgjkg, maximum). 'lherefore, incidental
ingestion of contaminated soils, inhalation of fugitive dust, arrl dennal
absorption of VOCs from the surface arrl subsurface soil should not be a
health concern. SUbsurface soils contain higher concentrations of VOCs
(PCE-100 rrgjkg, maximum).
'lhe ingestion of on-site untreated groun:iwater would pose a health
threat. It is ass\.lll'ed for the purposes of this Health Assessment that
enployees are not currently drinking the untreated groun:iwater or using
the water for washing or showering, although the untreated groun:iwater is
currently being used in the production processes. 'lhe inhalation of the
VOCS released during the production process may be a health concern if
high concentrations are reached. Applicable OOHA guidelines for VOCS
inhalation exposure would apply during these enployee exposure periods.
No data were provided to conunent on the health :il!lplications.
Since the contaminated on-site groundwater does not appear to have
migrated past the site boundaries, the off-site users of the shallCM arrl
deep groun:iwaters should not be affected. Public health :il!lplications
relating to ambient air arrl surface water cannot be made because of the
absence of data.

'!he following is a general discussion of the effects of exposure to high
levels of PCE, 'K:A, TCE and DCE and is for infonnational pm:poses. 'lhese
effects are not expected to occur from the known exposure pathways found
at this site.
PCE, urrler acute exposure conditions, may cause central nervous system
(eNS) depression, hepatic injury, and anesthethic death. Kidney damage
and canliac arrhythmias have been produced in animal experiments.
Olrerexposure symptoms include malaise, headache, staggering gait, and
slowing of mental ability. PCE has been found to be carcinogenic in
laboratory animals, and is classified as a probable human carcinogen by
the EPA. .Routes of entry are inhalation, skin absorption, and ingestion.
Target organs and systems are liver, kidneys, eyes, respiratory system,
and eNS.
may also cause dry, scaly dennatitis of the skin from
repeated or prolonged exposure. 'K:A also acts as a narcotic and eNS
depressant. Acute exposure symptoms include dizziness, drowsiness,
incoordination, unconsciousness, and death. '!his chemical is not thought
to be carcinogenic to humans. Routes of entry are inhalation, ingestion,
and skin absorption. Target organs and systems are the eyes, skin,
canliovascular system and the eNS.
'K:A exposure
Repeated skin contact to TCE may cause dennatitis. Acute exposure
depresses the eNS with corresponding symptoms of headache, vertigo,
trerrors, nausea, canliac arrhythmia, blurred vision, vomiting, and
intoxication similar to alcohol. '!here have been reports of
unconsciousness and death. TCE addiction and peripheral neuropathy have
also been reported. Although no evidence of human carcinogenicity from
exposure to this chemical has been found, animal experiments (mice) have
produced hepatocellular carcinomas that spread to the lungs; based on such
infonnation, TCE has been classified by the EPA as a probable human
carcinogen. Routes of entry include inhalation, dennal absorption, and
ingestion. Target organs and systems are the heart, liver, kidneys, skin,
eNS, and lungs.
DCE can act as a primary irritant producing dennatitis and irritation of
the mucous membranes. DCE functions as a narcotic, causing eNS
depression. Acute exposure may cause symptoms of dizziness, nausea,
frequent vomiting, and eNS intoxication similar to alcohol. Renal effects
are transient following cessation of exposure. Routes of entry are
inhalation, dennal absorption, and ingestion. Target organs and systems
are the eNS, eyes, and respiratory system.
CONCIDSIONS AND RECXM1ENDI\.TIONS
Conclusions:
'!his site is of potential health concern because of the risk to human
health resulting from possible exposure to hazardous substances at
Page 7
concentrations that may result in adverse health effects. As noted in the
Pathways above, h1.1111ai1 exposure to PCE, 'ICE, TCA, and IX:E
may occurjbe occurringjhave occurred via ingestion, inhalation, and dennal
abso:rption.
Human Exposure
'Ihe Kurt Manufacturing Company Site has VOC contamination of the on-site
soil and groundwater. 'Ihe VOC indicator chemicals of ·concern are PCE,
'ICE, TCA, and IX:E. 'Ihe site surface and subsurface soils do not pose a
health concern from incidental ingestion or dennal abso:rption. 'Ihe extent
of groundwater contamination does not appear to extetn beyond the site
boundaries. Off-site private well users are thought not to be affected by
this contamination. HCMeVer, no private well data were available to
support this conclusion. 'Ihe ingestion and use of on-site groundwater
without treatnent may result in adverse health effects. CUrrently, the
on-site groundwater is used in the manufacturing process as production
water. Inhalation by enployees of VOCs that may volatilize from the
production water is probable; applicable OSHA standards/guidelines should
be follCMed to safeguard potentially exposed workers. Re!redial actions to
date have been the reiroVal of the SUirp pit, capping of the SUirp pit area
with an inpenneable material to limit infiltration of rainwater, the
installation of a groundwater pump-out system to limit migration of the
contaminated groundwater, and abandoning and capping the shallCM
production well :i.rrplicated in contaminating the lc:Mer aquifer by
contaminant migration through the annular space along the well casing. No
ambient air data or surface water data were provided for an evaluation of
these pathways.
Recomme!x'lations:
1. Ambient air monitoring and surface water data are needed to complete
an evaluation of the site erwiromnental media.
2. Sanpling and analysis of the nearest off-site d=ngradient private
wells (in both shallCM and deep aquifers) are recanunended to confinn the
asSUirption that off-site private wells are not affected.
In accordance with the Ccmprehensive Enviromnental Response, Ccmpensation,
and Liability Act (CERcrA) of 1980, as amended, the Kurt Manufacturing
Company Site has been evaluated for appropriate follCM-up with respect to
health effects studies. Inasmuch as there is no extant documentation or
indication in the infonnation and data reviewed for this Health Assessment
that h1.1111ai1 exposure to on-site or off-site contaminants is currently
occurring or has occurred in the past, this site is not being considered
for follCM-up health studies at this time. HCMever, if data become
available suggesting that h1.1111ai1 exposure to significant levels of
hazardous substances is currently occurring or has occurred in the past,
ATSDR will re-evaluate this site for any indicated follCM-up.
