1534 Lone Oak Rd - Final report soils testingFINAL REPORT
ON
INVESTIGATION AND EVALUATION
OF
LONE OAK ROAD DISPOSAL SITE
DAKOTA COUNTY
ENVIRONMENTAL MANAGEMENT DEPARTMENT
JULY 24, 1996
Introduction
The Dakota County Environmental Management Department (Department) has
the responsibility of enforcing ordinances that regulate solid waste, hazardous
waste and water quality management in Dakota County. The Department has
also organized special teams, as needed, composed of solid waste, hazardous
waste and water quality staff to investigate known or suspected contaminated
sites in the County.
When a report concerning a rubber dump site on Lone Oak Road in Eagan was
received, a team was forrned to determine what contaminants might be present
on and/or leaving this site and what potential health and safety concerns and
environmental impacts might exist.
Background
On April 15, 1993, a citizen reported to the Department that they had uncovered
buried waste rubber during abandonment of a septic system and installation of
municipal water and sewer lines at a residence on Lone Oak Road in the City of
Eagan. Department staff inspected the site and verified that rubber products
such as tires, tire parts, hoses, boots, and inner tubes were buried under
approximately four feet of sandy fill cover in the areas being excavated to the
south and east of the house on Lone Oak Road.
At that time, this residence relied on a private well for its water supply. To
determine whether the disposed material had any immediate impact on the
drinking water supply, Department staff sampled the water from the well at the
residence on Lone Oak Road on May 4, 1993, and analyzed the samples for
heavy metals, volatile organic compounds, poly nuclear aromatic hydrocarbons,
total organic carbon and inorganic indicators of water quality. These are
constituents that cause or are indicators of health impacts in water supplies.
Pace Laboratory did the actual analysis and found silver to be pre"sent at a
concentration above the recommended allowable level for drinking water, as
determined by the Environmental Protection Agency. In August 1993,
Department staff again sampled and analyzed the water from the well at the
same residence on Lone Oak Road, and on that occasion detected no metals in
concentrations that exceeded recommended allowable levels.
Available aerial photographs and topographic maps were studied and it was
determined that the disposal site could cover up to three acres and that 6 homes
could be affected. The aerial photographs showed activity in the area, including
haul roads, that indicated that filling had been done. The location of the area
and affected homes is shown on the attached maps (see Attachments 1a and
1 b).

During 1994, Department staff gathered background information at the Historical
Society and conducted interviews with longtime residents of the area as well as
waste haulers. Anecdotal accounts referred to the burial of tires and rubber
products in the Eagan area that were collected as part of the World War II
materials salvage efforts. One longtime resident of the area specifically stated
that rubber collected by the Labor Volunteers for Victory Program and stockpiled
at Fort Snelling was dumped in this area in 1946-1947. Department staff also
contacted the Army Corps of Engineers in an effort to locate records from that
era. Army Corps personnel indicated that they were not aware of any records
pertaining to this site or any means of locating any records that might exist.
Preliminarv Evaluation
In the second half of 1994, Department staff developed a plan for characterizing
the site to the extent necessary to determine any potential impact from the
buried rubber, particularly impacts on the health of the residents in the area. The
County aiso contracted with a consultant to do a geophysical survey of the site in
Spring 1995. Site access was necessary to conduct this survey, and the
Department obtained signed access agreements from all six homeowners in the
area.
The geophysical survey of the site was conducted on June 5-7, 1995, by Fromm
Applied Technology (Fromm), an environmental consulting firm based in
Mequon, Wisconsin. On those dates, Fromm took numerous measurements at
the surFace while walking over the entire suspected disposal area. The
equipment was hand-held and had no physical impact on the land or the buried
material. Fromm representatives computerized the data and prepared charts
and maps that depicted the perimeter and approximate depth of fill. The results
of this survey were consistent with the information obtained from the aerial
photographs and topographic maps. Department staff confirmed that the
disposal site covered two and one-half to three acres with six houses-either on
the disposal site or near the perimeter of the site.
Fromm also took magnetometer measurements to determine the presence of
6uried metal objects. Fromm determined that there was no indication of large
metal objects in the fill. (See Attachment 2- Report on the Electromagnetic and
Magnetic Surveys Conducted at the Dakota County's Lone Oak Site, Dakota
County, Minnesota, July 18, 1995).

Subsurface Investigation
Following the Fromm study, the Department contracted with Braun Intertec, an
environmental consulting/services firm, to do a subsurface investigation. In
October 1995, Braun Intertec used a large mobile unit to bore one vapor
monitoring well and three temporary monitoring wells at a property on Lone Oak
Road, the location selected based on the Fromm geophysical survey.
Braun Intertec constructed three temporary monitoring wells on the selected
property to measure depth to ground water and to take samples of the ground
water. This enabled Department staff to chemicaliy analyze the ground water
samples to determine if there had been any contamination and what risks, if any,
might have resulted from such ground water contamination. After the sampling,
all of the welis were sealed.
The water samples were taken with a ten foot pertorated PVC pipe section that
was installed a few feet into the watertable. The water samples contained
various amounts of sand, silt and clay sediment. The ground water was found to
be high in total metals before filtering the sample to remove the sand and
sediment, but after filtering most of the metals were below the method detection
limit (the lowest concentration that could be determined by the laboratory
procedure). The chemicals found in the water were determined to not exceed
the recommended allowable limits for drinking water.
A separate vapor monitoring well was installed on the upper level of the selected
property for sampling any gas that might be present in the waste. A perForated
PVC pipe was installed into the waste to collect gas samples. The samples were
analyzed for gases that were present. Methane was the only gas of concem that
was detected, with a concentration of about 16%.
While drilling the vapor monitoring well, waste at various levels and the soil
below the waste were also sampled. The waste that was obtained through the
boring was a mixture of soil and rubber pieces. Two samples were taken from
the waste rubber for analysis: one at a depth of ten feet, and one at a depth of
twenty feet. One sample was also taken of the soil below the waste, at a depth
of twenty-five feet. The samples of waste rubber tested high in a number of
metals, especially lead, but the soil below the waste tested very low in metals.
After completing these field tests, Braun prepared a report summarizing the data
that was gathered. This report was completed on November 22, 1995, and
indicated two issues of concern: the high methane concentration in the vapor
monitoring well; and, the high levei of lead in the waste material itseif. (See
Attachment 3, SubsurFace Investigation, Rubber Disposal Site, 1534 Lone Oak
Road, Eagan, Minnesota, November 22, 1995).

The presence of inethane gas was considered by Braun and Department staff to
be the most immediate concem to heaith and safety. With an adequate supply
of oxygen and an ignition source, methane gas at the level detected during the
Braun sampling could result in an explosion if the methane gas were
concentrated in an enclosed area. Therefore, the Department's first concern
was possible migration of the methane gas into homes and buildings where
oxygen coupled with an ignition source could be present. To determine what
was occurring and ensure the safery of the residents, the Department then took
the following steps:
. checked for the presence of inethane gas in the basement of each home in
or near the disposal site in late October, 1995. The basements were checked
again in January, 1996, at the owner's request. No methane gas was
detected in those homes on these occasions.
. had NSP do a fingerprint test on the methane gas detected in the vapor
monitoring well. NSP indicated that it was nof natural gas from a leak in the
gas distribution line.
• had probes installed at depths of about four feet and six feet next to the
basement at a residence on Lone Oak Road to test for methane near the
house. No methane gas was found at these locations.
The high levels of lead reported to be in the waste were a concern because of
the possibility that people could be exposed to lead from waste that had come to
the surface or from surface soils that had been contaminated.
The sfiallow ground water samples tested low in volatile organic compounds, i.e.,
below drinking water standards. Based on these and other analytical results,
Department staff and Braun concluded that there was no evidence that industrial
wastes other than rubber materials were disposed on the site. This was
consistent with the finding of the work done earlier by Fromm. After reviewing
the test results, Department staff were also convinced that there was not likely to
be a ground water probiem caused by lead or other metals associated with the
waste migrating from the site. In addition, the water from this surficial aquifer
was not used by area residents for drinking water. Therefore, Department stafF
had no immediate concerns about the environmental impact of the rubber waste
on the ground water and planned no further testing or evaluation of the ground
water. The Lone Oak Site was placed in the County inventory of known or
suspected contaminated sites. The ground water in this area may be
investigated further at a later date, if warranted.

Findings
1. Public Health and Safety Imaacts
The study of any impacts on public health and safety from the rubber waste that
was used as fill at this site has now been completed to the satisfaction of the
Environmental Management Departrnent. The presence of nuisance rubber at
the surface will be an irritation and an ongoing problem in terms of land use for
residents to contend with, but based on the results of the DepartmenYs
investigation, the disposed waste rubber, if undisturbed, does not present a
heaith or safety problem.
• METHANE GAS
The methane gas detected in the Lone Oak Area does not appear to be a
serious health or safety concem. The subsurface presence of inethane gas on
the residential property where most of the testing was done on Lone Oak Road
has been verified. Although all six residential lots in the Lone Oak Road area
have not been extensively evaluated, the Department believes that the methane
gas is limited in distribution. The property at that specific location on Lone Oak
Road was connected to city sewer in 1993, and the existing septic system was
abandoned. Based on the physical properties of rubber, the DepartmenYs
consultant, Braun Intertec, and Department staff believe that the rubber waste is
not the source of the methane gas. With no other source attributable, the
presence of inethane gas appears to be caused by residual septic waste that
continues to decompose and produce the methane gas. Current and former
area residents have stated that the location of the methane monitoring probes on
this property are in the location of the old septic system. Therefore, methane
gas would be expected to be found at this location.
Each of the six homes in the Lone Oak area have been monitored for methane
gas in the basements and near the foundations outside of the homes. Methane
gas was not detected on any occasion. Outbuildings that are present behind
some of the homes were also monitored for methane gas and none was
detected.
Methane gas at certain levels can result in an explosion if the methane gas is
concentrated in an enclosed area and if an adequate supply of oxygen and an
ignition source are present. These conditions have not been found in or near
any of the houses in this area.
Braun Intertec recommends, however, that residents have methane monitoring
detection systems with alarms installed in their basements. They also
recommend that residents have methane probes installed outside the basements
of their homes and monitored periodically.

}
• LEAD METAL
The concentration of lead found in the surface soils in the disposal area does not
appear to be a health concem. The lead concentration in surface soil samples
collected during the evaluation of this site was generally found to be well below
the 100 ppm standard recognized by the State Health Department and well
within acceptable levels normally found as background lead 4evels in soil. The
one sample that tested high in lead was still below HUD health concerns and it
was a single sample from an area that had been disturbed due to an excavation.
Residential exposure to 4ead is minimal, especially from soils that are not
disturbed. Exposure can be reduced further, if desired, by keeping some type of
cover on the soil (a good grass cover or wood chips), and by refraining from any
excavation activ'ity that goes below the top four to six feet of cover soil, into the
soillrubber waste material.
Construction projects in this area may require excavation that could result in
residents being exposed to lead-contaminated rubber waste. Analytical testing
that was done on this site indicates that the chances of encounter+ng higher
levels of lead will increase with excavations into the waste. Any excavation of
soil/rubber waste should be done in a manner that will reduce dust and water
runoff. This could be achieved by placing the soil/rubber waste directly into a
rolloff container to avoid contaminat+ng the surface soils and by covering piles of
excavated materiai with plastic tarps until removed from the site. Any rubber
waste or contaminated soil that is excavated should be removed completely from
the site and must be disposed properly in accordance with local, County, and
State requirements.
2. Environmentallmpacts
The Department does not intend to further investigate or perform any add'+tional
work at the Lone Oak Road ruhber disposal site. The Lone Oak Road rubber
disposal site will be placed in the Dakota County inventory of known disposal
sites and further evaluated at a later date if new information arises.
3. Land Use Imoact
The most serious impact from the presence of rubber waste on the properties in
the Lone Oak area will be during construction projects. in addition to the
precautions described above that they will need to take, residents may be
inconvenienced by rubber on the surFace or rubber encountered during
construction.

Dear Mr. Erickson:
Re: Subsurface Investigation, Rubber Disposal Site, 1534 Lone Oak Road, Eagan, Minnesota
As authorized by Dakoca Counry, Bnun Intertec Corporation has completed addirional
investigarion az the referenced site. Our results, conclusions and recommendations ate described
in the following letter report and attachmenu.
Scope of Work
1. Mettiane F.xtraction Test
On May 10, 1996, Braun Incertec conducted a methane extraction test to qualitatively assess the
extent of che methane and the radius of influence which might be expected from a methane
extraction system. To conduct this test, a vacuum of 18 inches water was applied to VW-i and
selected probes were monitored during the test. All of the vaQor pro6es were monitored prior to
conducting the test and iuunediateiy after comQletion of the test.
2. Methane Monitoring
In addition to the mechane extraction test, the meshane probes were monitored on a weekly basis
for three weelcs after the test (three monitoring events).
3. Chemicai AnalYsis of Sail Samples
Dakota County personnei collected surface soil samples from rhe site and adjacent residences on
May 16, 1996. For chis procedure. 64 sample locations consisting of 180 square feet were
plotted. Ten of the 64 sample locations were randomly selected. Wirhin each of the ten
locarions, three soil samples were collected and composited intovne sample. These samples were
analyzed by the Braun Intertec laboratory for arsenic, barium, lead, cadmium and chromium. Six
additionai soil samples were collected from selected locations and analyzed for lead only.
4. Sampling and Anatysis of Resideutiai Water R'ell SamPle
Braun Intertec collected a wacer sample from the weil ac the Holland residence. T'he samples were
analyzed by the Braun Intertec laboratory for the parameters listed below.

1. Methane F.xtradion Test
Data coilected during the methane extraction test aze provided in Table 1. These data indicate the
following observazions:
In general, the vacuum leveis measured at the vapor probes increased as the methaae
extraction tesc progressed. The test was terminated afrer the vacuum field (i.e., azea of
influence) had stabili2ed.
The vacuum radius of influence around VW-1 shows directional variability. Using the
criteria of 0.1 inches wazer to define the limit of influence, the radius of influence caused
by creating a vacuum of 18 inches water u VW-1 is estunated to be: becween ZS feet and
40 feet to the nonh, less than 40 feet to the east, greater than 60 feet to the south and
greater than 40 feec to the west. This observarion suggests heterogeneity in the
permeability of the rubber fill.
T'he methane concentrarions in the sod gas extracted from VW-1 decreased as the test
progressed, from 21% befare the test to 14% az che conclusion of the test. Aowever,
because methane concentrations tend to be relatively variable over small periods of tune
under noimal conditions, t6is decrease is not necessarily significant.
Based on the results of this test, no conclusions can be made regarding the extent of rhe
methane or the raze at wtrich it regenerates. A longer test, lasting several days, might
provide greater insight into these topics.
2. Methane Monitoring
Methane monitoring data obtained to date for the site are summarized in Table 2. Methane has
been detected at 7 of the 14 monitoring points. None of the pmbes located adjacent to houses
exhibited methane concencrations. 1'he lateral extent of the mechane has not been clearly defined
to the east and west, aithough methane was noc detected in Probe H located 30 feet east of the
area of known me[hane impacu (Figure 1). As indicaced in t6e attached o aQh, mechane
concentra[ions have flucmated az the site. Nieasuremenu of inechane concentrations in subsurface
soils are typically variable and can be affecied by factors such as bazometric pressure, the
presence of frost in the ground, etc.

3. Soil Analytical Resuits
Results of the surface soil sample analysis aze summazized in Table 3, and the laboratory report is
attached. Other than lead,the concen[rations of inetals appear to be consistent with naturally
occurring levels. The lead concentratioos in the majority of the samples also appear to be
consistent with naturally occurring levels. The lughest concentration of lead detected az the site is
320 mg/Kg (ppm); all other concentrations were below 100 ppm.
There are two applicable standazds for evaluating lead concentradons in soIl relarive to human
health risk. The first of ihese is che Minnesota Departmeat of Health Lead Hazard Reduction
Program standazd of 100 ppm. The second is the Housing and Urban Development Lead Risk
Assessment Guideline standazd of 400 ppm for lrigh comact ueas such as sandboxes and gazdens
and 2,000 ppm for the dwelling perimeter and yard.
4. Ana[yticai Results for Residential Water WeII Sample
Results for the Holland water well sample aze provided in the attached laboratory repoa. None
of the organic paramesers were detecced in the sample. The concentrarions for the inorganic
pazameters appear to be within normal ranges and meec drinking wazer quality standards. It
should be noted that the method detection limits for cadmium and selenium (which were not
decected in the well) aze slighdy above the Minnesota Department of Health Health Risk Limit
(HRL)•
Conclusions and Recommendations
Based on the results of ttus addidonal investigation and previous work az the site, the most
significant and immediaze risk at t6is site is associated wizh the methane. Concemrations at four
sampling locations have been above the lower explosive limit. At this cime, our monitoring
results do not indicate the presence of inethane nezt to the foundations of the houses. However,
the potential exists for the methane to migrate. Therefore, we recommend that the houses which
are in contacs or close prmcimiry to the waste rubber be equipQed wiEh a methane detection and
alann system. This system shouid include probes along che ouuide oi the house founda[ion which
aze periodically monitoced as well as a mechane detector and alarm in the basement.
The source of the methane remains unclear. Methane is produced by the breakdown of organic
material. Therefore, the rubber waste is an unlikely source. The nibher waste does appear to be
serving as sort of reservoir for the methane due to ics porous nanue. Assuming rubber is the only
waste mazerial buried at this locanon, the most likely source for [he methane appears to be
previously used sepric systems.
Elevated concentrations of some mecals have been detecced in associa[ion with the buried ru6ber
waste. However, surface soil samples exhibited merals concen¢ations within the range of
naturally occurring levels, wich the excepdon of one sampie which showed eleva[ed lead
concentradons. The buried wasce should noc pose a significanc risk to health or the environmenc
as long as it rema;ns undisturbed. The srandazd mirigarion measute for elevated concen[rations of
lead in surface soils is to remove the soils or cover them. Cover mazerials can consist of sod,
paving material, or other material such as sand or wood chips.
