7.0 Nature and Extent of Contamination at Operable Unit 4
This section discusses the nature and extent of groundwater and soil contamination identified at the
Operable Unit 4 (OU 4) source areas DP25, ST27, WP33, SS35, SS36, SS37, SS39/SS63, ST58, and
SS64.
7.1 Contaminants of Concern
OU 4 consists of a series of past-practices source areas that were characterized by drum disposal,
asphalt-cement handling, road-oil mixing, and sludge disposal operations. Therefore, a variety of
contaminants-would be expected at these source areas. Because of the nature of the operations, most of
the contaminant sources would be expected to be of relatively low volumes (such as drums). However,
two of the reported sludge disposal areas, DP25 and ST27, are located within active fuel storage tank
complexes, where large volumes of petroleum hydrocarbons are handled.
Any number of chemical components could have been stored in drums. Solvents and fuel hydro-
carbons were sometimes used at asphalt-cement handling areas for cleaning and diluting the asphalt
cement. Waste oils and fuels were used in road oiling operations. Chemicals that have been detected
in previous work at these sites include pesticides (particularly DDT and its decomposition products
DDD and DDE); lead and chromium (from paint); total petroleum hydrocarbons (TPHs) and polycyclic
aromatic hydrocarbons (PAHs) from asphalt cement; benzene, toluene, ethylbenzene, and xylene
(BTEX) from fuels and solvents; and chlorinated hydrocarbons from solvents. Compounds that might
be expected, but were not detected in significant quantities, include polychlorinated biphenyls (PCBs)
and ketones (paint solvents).
7.2 Source Area DP25
DP25, the E-6 Fuel Storage Tank Area, (shown in Figure 2.1) is located north of Quarry Road,
adjacent to the E-ll Fuel Storage Tank Area, ST27. Six 4.78-million liter and two 800,000 L above-
ground tanks are enclosed by a fence in a 210- by 340-m (229- by 372-yd) area. A single 16 million-
liter above-ground tank is enclosed by a separate fence to the east of the main tank farm area. The fuel
storage tanks were installed, with their underground piping and valves, in 1955 or 1956. Until 1992,
the E-6 Tank Farm was used for storage of JP-4 jet fuel. Beginning in 1992, the tanks were converted
to JP-8 fuel storage. The main fuel-product line feeding the tanks runs along Quarry Road. Weathered
sludge from periodic cleaning of fuel tanks was buried in shallow trenches between the fuel storage
tanks until 1980 (CH2M Hill 1982). The sludge consisted primarily of water, rust, dirt, and fuel. The
trench or burial areas have never been located, despite a search of aerial photographs and old records
in 1992. In 1987, a pipeline fuel spill of JP-4 reportedly occurred along Quarry Road adjacent to the
source area.
The potential sources of contamination in DP25 are spills and leaks from the fuel storage tanks and
their associated piping within the E-6 POL (petroleum, oil, and lubricants) Storage Area. The major
contaminants of concern expected from fuel spills would be BTEX and lead. Additionally, the sludge
from periodic cleaning of the tanks could be a source of lead contamination.

7.2.1 Soil Contamination
Soil samples were collected from soil borings and analyzed for the constituents listed in Table 5.6.
Soil contaminants greater than EPA risk-based screening levels or background concentrations for DP25
are summarized in Table 7.1. A summary of the sample concentrations can be found in Appendix A.
Because DP25 is an active tank farm, the area is considered industrial. The 870,000 /xg/kg of lead
(Table 7.1) at DP25 does not exceed the EPA industrial action level of 1,000,000

BTEX constituents are curiously absent from soils at DP25, possibly because the water table is
shallow at this site, often within two feet of land surface. Leaks in tanks or buried pipelines would
have released fuel directly into the groundwater. Soils would be contaminated at the leak site or
distributed in a layer over the area covered by the floating fuel. Because these latter soils are near land
surface, volatile constituents such as the BTEX compounds could evaporate.
7.2.1.1 Floating Fuel No floating fuel was detected at DP25 in 1986, but was detected in
measurements made from 1988 through 1993. During this period of time, fuel thicknesses in the
monitoring wells ranged from no floating fuel to 0.33 m (Table 7.2). The floating fuel samples from
these wells were identified as JP-4. The greater thickness of product in Well B-15 in June 1992 may
have been related to the increased recharge from spring snowmelt. No floating fuel has been detected

pipeline break along Quarry Road.
7.2.2 Groundwater Contamination
Groundwater contaminants greater than EPA risk-based screening levels or background concentra-
tions for DP25 are summarized in Table 7.3. A summary of the groundwater sample concentrations is
presented in Appendix A. Groundwater samples were collected from soil borings and analyzed for the
constituents listed in Table 5.6.
Significant lead concentrations were detected in 1988 groundwater samples from wells inside the
main fence and ranged from 291 to 362 /zg/L (see Figure 7.1). Outside the main fenced area, lead
concentrations that exceed the maximum contaminant level (MCL) of 15 fig/L were detected in 1988 in
three wells located west of the tank farm and in two wells east of the tank farm. Lead results varied
from 1988 through 1993 somewhat erratically but were generally lower in 1993 (Figure 7.2) than in
1988. Lead also appeared to decrease in the downgradient wells. The lead distribution appears to have
expanded between 1988 (Figure 7.1) and 1993 (Figure 7.2) only because of the additional monitoring
locations in 1993. The source of the lead plume in the monitoring wells to the west of the facility is
not known, as lead is expected to be less mobile in groundwater than BTEX. One of the unlocated
sludge pits could be the source of this contamination.
In 1988, BTEX was detected in groundwater at a number of the wells within the fenced areas of the
tank farm. Significant benzene concentrations in groundwater at the wells in the main fenced area
ranged from 46 to 290 ng/L, with the concentration of benzene near the large tank to the east reading
7900 /xg/L. Toluene concentrations in three wells in the main tank farm area ranged from 1200 to
34,000 fJLg/L; near the large tank, the concentration was 24,000 /xg/L. Based on these data, the appar-
ent extent of the VOC plumes appeared to be limited to the fenced area, as shown in Figures 7.3
and 7.4.
BTEX was also detected at high concentrations (900 to 4700 figfL) in 1988 in groundwater at Well
53M01 near the reported 1987 pipeline fuel spill. A hydrocarbon identification test of the groundwater
sample showed the source of the contamination to be motor gasoline, although the spill was reportedly
JP-4 fuel. VOCs were fairly low (< 10 mg/kg) in the adjacent soil, indicating that most of the product
had already volatilized or migrated to the groundwater.
The results from 1992 show that BTEX contamination still existed at DP25 for the two monitoring
wells sampled inside the bermed areas; concentrations have decreased by about a factor of 3 between
1988 and 1992. These observations, coupled with the essentially static amount of floating product
since 1988, indicate the source of contamination at this site may have already ceased. Groundwater
samples collected in April 1993 from downgradient wells indicate that contamination from DP25 has
not migrated, in significant concentrations, beyond the bermed walls surrounding the tank farm (see
Figure 7.5). Data from a microwell study in 1994, also indicate that BTEX contamination is still
confined inside the E-6 tank farm berm (Nerney et al. 1994). No contamination was detected in any of
the microwells north of DP25. No evidence exists that any contaminants, except lead, have spread
beyond the bermed and fenced area of the facility..

7.3 Source Area ST27
ST27, the E-ll Fuel Storage Tank Area, (shown in Figure 2.1) is a fence-enclosed complex of five
fuel tanks on the south side of Quarry Road approximately 600 m (654 yd) southeast of Hardfill Lake.
At present, the E-ll Tank Farm is used for storage of jet fuel (JP-4 until 1992, now JP-8). The
8.72 million-liter above-ground tanks were installed in 1972 and are cleaned at 3- to 6-year intervals.
Before 1980, the sludge from cleaning operations, composed of water, rust, dirt, and fuel, was buried
in shallow trenches within the storage area. The trench burial areas have never been located, despite a
search of aerial photographs and old records in 1992. Since 1980, the sludge has been drummed and
shipped off-base for disposal.
The potential sources of contamination in ST27 are spills and leaks from the fuel storage tanks and
their associated piping within the E-l 1 POL Storage Area. The major contaminants of concern
expected from fuel spills would be BTEX and lead. Additionally, the sludge from periodic cleaning of
the tanks could be a source of lead contamination.
7.3.1 Soil Contamination
Soil samples were collected and analyzed for the constituents listed in Table 5.7. No soil
contaminants above EPA risk-based screening levels or background concentrations were identified for
ST27. A summary of the soil sample concentrations is presented in Appendix A.
7.3.2 Groundwater Contamination and Floating Fuel
Groundwater contaminants greater than EPA risk-based screening levels or background concentra-
tions for ST27 are summarized in Table 7.4. Groundwater samples were collected and analyzed for the
constituents listed in Table 5.7. A summary of the groundwater sample concentrations can be found in
Appendix A. No floating product was found at ST27 during surveys in 1987, 1988, and 1992. In
addition, all of the 1992 VOC and BTEX analyses were below detection at all of the wells in and
around ST27 (see Figures 7.3, 7.4, and 7.5.) None of the well samples, either within or downgradient
of ST27, has shown any evidence of POL contamination. These tanks were installed in 1972 and have
been maintained periodically since that time. It appears that these tanks have better integrity than those
at ST10 and DP25, and no fuel leaks have occurred at this site.
A number of the wells within the source area boundary did show low levels of lead contamination.
In June 1992, one well (B-13) showed a significant lead concentration (120 ng/L). The high lead
results for Well B-13 were not confirmed when the well was resampled on 1993 (Figure 7.2).

7.4 Source Area WP33
WP33, the effluent infiltration pond, is a 7.7-hectare (19-acre) unlined pond into which treated
liquid effluent from the wastewater treatment plant is discharged. It is a major portion of the existing
Wastewater Treatment Plant at Eielson AFB (Figure 2.1 and 7.6). The plant is on a separate access
road from Central Avenue, about 0.5 km (0.3 mi) northeast of the main gate. The pond has been in
use since 1979.
The wastewater treatment plant, built in 1953, currently treats most of the base domestic and
operations wastewater. Some operations waste streams are treated by 12 distributed oil-water
separators. The average daily flow through the plant in 1982 was 3400 m3/day (900,000 gal/day)
(CH2M Hill 1982). Before 1973, primary treatment was effected through three clarifiers and two
sludge digesters. The plant was expanded in 1973 to include secondary treatment at two aeration
lagoons and a chlorination system. Until 1979, effluent was directly discharged to Garrison Slough
under a National Pollution Discharge Elimination System permit (No. AK-002089-3). This permit
requires routine monitoring of discharge waters for sanitary sewer parameters, chemical oxygen
demand, and oil and grease. These parameters were frequently above normal, indicating unauthorized
POL disposal or releases.
Wastewater entering the plant may have included wastes generated by spent solvents, deicers, and
degreasers from shops and other repair facilities disposed of into storm drains, accidental discharges of
these and other industrial chemicals, and photo shop and laboratory waste reagents from sinks and floor
drains. The wastewater may also have included contaminated wash-down waters from runways, drive-
ways, and roads; fire training pit discharges; dust suppressive oils; excess herbicides; pesticides; PCB;
wood preservative containing solutions; spillage; and a variety of household and office supplies
discharged through sanitary sewer outflows.
The infiltration pond, WP33, is engineered to discharge groundwater to the vadose zone, thereby
disposing of treated wastewater effluent. According to conversations with Eielson AFB staff, the pond
appears to be increasing in volume, evidenced by the increase in pond surface area over the last several
years. This increased area would suggest that siltation of sediment or organic material has created a
less permeable substrate. Groundwater monitoring data indicate that WP33 has not impacted the
groundwater quality in the area. Nevertheless, historical data suggest the pond sediments may be
contaminated from past practices. It is possible that future changes in the hydrology of the site or the
operation of the ponds could expose pond sediments. No soil or groundwater contaminants greater
than EPA risk-based screening levels or background concentrations were identified for WP33. A
summary of the groundwater sample concentrations for WP33 is presented in Appendix A. Ground-
water samples were collected and analyzed for the constituents listed in Table 5.8.

7.5 Source Area SS35
SS35, the Asphalt Mixing and Drum Burial Area, (shown in Figure 2.1) is located in the central
part of the base adjacent to Central Avenue, about 0.3 km (0.2 mi) south of the Water Treatment Plant.
SS35 was used as a mixing area from the early 1950s to the late 1960s. Asphalt cement was mixed
in a tank and then used for road maintenance. Commingled waste oils and solvents were mixed with
contaminated fuels and used for road oiling to control dust. Approximately 200 empty asphalt-cement
drums were reportedly disposed of along the banks of Garrison Slough (CH2M Hill 1982). A ground
tour of the site showed no evidence of the empty drums or the areas saturated with asphalt cement. It
was speculated the drums might have been removed for proper disposal. The area was also apparently
used for pesticide mixing and pesticide equipment cleaning operations.
The source area currently is inactive and covered with mowed grass. The only indications of past
activities are several areas where asphalt cement and gravel are visible at the surface.
A number of potential sources of contamination at SS35 have been identified, including surface
spills of asphalt cement, waste oils, solvents, contaminated fuels, and pesticides from the asphalt-
cement mixing operations; pesticide mixing and cleaning operations; residual materials in buried
drums; and metal, concrete rubble, and demolition debris remaining in the source area. Soil and
ground water samples were collected (see Figure 7.7) and analyzed for the constituents listed in
Table 5.9.
Geophysical studies have been conducted at SS35 to identify potential locations of buried drums
and other materials. During the 1988 geophysical investigation, two anomalies (anomaly areas A and
B) indicating possible buried drums were identified (HLA 1989). The first anomaly (A) was a 23- by
69-m (25.2- by 75.5-yd) area identified in a location adjacent to Garrison Slough, roughly corres-
ponding to an excavation area identified on historical aerial photographs. The area did not appear to
have large numbers of buried drums, but does contain smaller areas concentrated with drums. The
second anomaly (B), oriented northwest to southeast near Garrison Slough, may be an abandoned
utility, such as a drainage culvert. Two small areas containing asphalt cement were present on the
ground surface in this area, and aromatic and chlorinated hydrocarbons were detected near the center
of the linear anomaly (B) in a soil gas survey.
It was concluded that metal debris and/or asphalt-cement drums had been disposed of in the trench
(HLA 1989). The linear anomaly (B) is referred to as the trenched area.
A geophysical survey in 1990 identified a third anomaly (C) in the northern part of the source area
extending about 38.1 m (41.7 yd) along the pond shoreline. Partially buried concrete rubble and
demolition debris were visible in the brush and trees at the shoreline. It was concluded the area
contained buried metal, concrete, and other demolition debris.
The contents of any drums buried at SS35 are generally unknown. In 1989, a number of drums
were uncovered during the connection of Building 3460 to the utilidor. The burial site of the drums
was located approximately 60 m (66 yd) east of anomaly area C, near the junction of the utilidor from
Building 3460 with the Central Avenue utilidor. The contents of one drum uncovered at this time were
analyzed for VOCs and semivolatile compounds (SVOCs) and metals. Its analysis is reported in
HLA (1990). The compounds detected would be expected to be present in waste oils used in road
oiling operations or waste solvent mixtures.

7.5.1 Soil Contamination
Soil contaminants greater than EPA risk-based screening levels or background concentrations for
SS35 are summarized in Table 7.5. Surface soils, subsurface soils, and sediments from Garrison
Slough were collected and analyzed for the constituents listed in Table 5.9. A summary of the sample
concentrations for SS35 is presented in Appendix A.
DDT and its derivatives were found in almost all surface and subsurface soil samples collected in
the 1988 and 1990 investigations. The highest concentration observed was 396 mg/kg in a surface soil
sample collected at 35SS03, located within anomaly area A near Garrison Slough. High DDT con-
centrations in surface soil were also observed at 35M01 (32.1 mg/kg), 35M02 (1.6 mg/kg) and two
surface soil locations. In all cases, DDT concentrations were higher than the DDD and DDE concen-
trations. DDT was less than 1 mg/kg in all subsurface soil samples tested. Heptachlor was found in all
soil samples tested in 1990 at concentrations less than 1 mg/kg. Chlordane was found in four of seven
soil samples collected in 1990 at levels up to 260
One sediment sample from the slough (35S01) was tested for pesticides in 1988. It was located
near the inlet of the pond Garrison Slough forms adjacent to the source area and showed 0.4 mg/kg of
DDD. DDT concentrations were lower, at 0.097 mg/kg. In 1990, a sediment sample (62S04) was
collected from the slough adjacent to SS35 just upstream of the pond. In that sample, DDT and DDD
were 62.4 and 58.6 mg/kg, respectively.
Surface soil samples from SS35 in 1992 were analyzed for PCBs (such as Aroclor), pesticides, and
lead. The results from the PCB analyses were at or below the detection limits reported by the ana-
lytical laboratory for soil samples. A summary of these sample concentrations is presented on
Appendix A.
The surface soil samples from SS35 in 1992 contained detectable concentrations of 4,4'-DDT and
derivative products 4,4'-DDD and 4,4'-DDE (Figures 7.8 and 7.9, respectively). The concentrations
were highest for the soil samples taken from anomaly area B. The lowest concentrations of 4,4'-DDT,
4,4'-DDD, and 4,4'-DDE were measured in samples from anomaly area C along the pond shoreline.
It is estimated that SS35 contains 765 m3 (1000 cu yd) of contaminated soil covering a 1500 m2
(16,000 ft2) area.

Groundwater samples from SS35 in 1992 were also analyzed for several other pesticide and organic
contaminants. The concentrations of these compounds in all groundwater samples that were analyzed
in August-September 1992 from SS35 were determined to be at or below the limits of detection.
Groundwater probes installed in the area showed some BTEX, chlorinated solvent, and lead contami-
nation. 1,1 dichloroethylene (1,1 DCE) was found in 17 of 33 groundwater probes, including 6 probes
with concentrations exceeding the drinking water standard. 1,1 DCE was not detected in the deeper
monitoring wells. Lead was detected at concentrations ranging up to 68 /xg/L, but this is likely due to
high turbidity of the samples. None of the water samples collected in 1992 from the eight monitoring
wells contained lead in excess of the 15 /xg/L screening level.
7.6 Source Area SS36
SS36, a drum storage site, is located in the central portion of the base, east of Industrial Drive and
south of the base power plant (see Figure 2.1).
SS36 was used as a mixing area for asphalt cement and the road oiling operations from the
late 1960s to the mid-1970s. In 1982, approximately 100 drums containing materials, such as waste
oils, hydraulic fluid, diesel, JP-4, Stoddard solvent, and methyl ethyl ketone, were stored in this area.
At that time, none of the drums were observed to be leaking; however, evidence of petroleum-
contaminated soil and a pool of petroleum-contaminated water appeared near the mixing tank used for
asphalt cement and waste.oils. A number of laboratory analyses were performed on groundwater and
soil samples from SS36 and the constituents are listed in Table 5.10. None of the available references
indicate that drums may have been buried at SS36.
A paint spill in the northeast corner of the area was reported in 1989 (SAIC 1989a). The soil
contaminated from the paint spill was removed in 1992. The paint spill was the source of the high lead
and chromium values in this area. The drum storage location and paint spill area are identified on
Figure 7.10.

7.6.1 Soil Contamination
No soil contaminants above EPA risk-based screening levels or background concentrations were
identified for SS36. A summary of the sample concentrations for SS36 is presented in Appendix A.
One surface soil sample showed a lead concentration of 7800 mg/kg which is significantly above the
EPA action level for lead in soil. However, this sample was collected directly from the paint spill area
prior to removal of the soil.
7.6.2 Groundwater Contamination
No groundwater contaminants above EPA risk-based screening levels or background concentrations
were identified at SS36. Groundwater samples were analyzed for the constituents listed in Table 5.10.
A summary of the sample concentrations for SS36 is presented in Appendix A.
BTEX and TCE were detected in a soil gas survey and in 14 groundwater probes installed at SS36.
However, no volatile compounds were detected in the 1992 groundwater samples collected from three
monitoring wells. One groundwater probe showed a lead concentration (44 /xg/L), above the EPA
action level for lead in drinking water. However, the groundwater probe samples were used as site
screening measurements, and are less accurate than the analysis of groundwater samples from the
monitoring wells.
7.7 Source Area SS37
SS37, the Drum Storage/Asphalt Mixing Area, is located approximately 90 m (98.4 yd) east of
Building 4333, just east of Flightline Avenue, between Quarry Road and Chena Street (as shown in
Figure 2.1). The site was used as a mixing area for road oiling operations and a mixing area for
asphalt cement from the mid-1970s to 1986. Some drums of miscellaneous liquid wastes were stored at
the source area. Their contents included waste oils, diesel fuels, jet fuels (JP-4), and Stoddard solvent
(PD-680). The drums have since been characterized, manifested, and disposed through the base
hazardous waste handling facility. None of the drums were observed to be leaking during the IRP
Phase I investigation; however, the ground surface appeared to be stained with petroleum, oil, and
lubricant (POL) (HMTC 1986). None of the available references indicate that drums may have been
buried at SS37. An area south of the storage area was used for fire-training exercises from 1976 to
1981. A number of laboratory analyses were performed on groundwater and soil samples from SS37.
Source area investigations in SS37 were conducted in 1984 (Dames & Moore 1985), in 1986,
1987, 1988 (SAIC 1989b), and in 1992 and 1994 (U.S. Air Force, 1995a,b,c). U.S. Air Force (1992,
Tables 10.2 through 10.5) summarizes analytical results from all sampling events.
7.7.1 Soil Contamination

7.7.2 Groundwater Contamination
Benzene at a concentration above drinking water standards was detected in monitoring Well 37-2 in
1986 (26 /ig/L) and in Well 37-3 in 1987 (15 /ig/L) (SAIC 1989a). All four wells at source area SS37
were sampled in 1992 and benzene was detected in all of the wells, with two of the wells showing
concentrations above the MCL (10 and 13 ng/L). Traces of free-phase product were found in one well
in February 1992, but were not confirmed in the summer of 1992.
By 1994, concentrations of all ground water contaminants had decreased to below EPA risk-based
screening levels or background concentrations at SS37. Groundwater samples were collected and
analyzed for the constituents found in Table 5.11. A summary of the sample concentrations for SS37
can be found in Appendix A.
7.8 Source Areas SS39 and SS63
Asphalt Lake (SS39) and the adjacent Asphalt Lake Spill Site (SS63) are located approximately
2 km (1.2 mi) south, of the Eielson AFB main gate. The two areas are separated by a gravel access
road. Five groundwater monitoring wells (39M01 through 39M05) exist at SS39, and one groundwater
monitoring well (53M02) lies approximately 100 m (109.4 yd) southeast (cross-gradient) of SS63.
Asphalt Lake was used as a disposal area for barrels and drums of asphalt cement after runway
construction in the 1950s. As these containers deteriorated and leaked, a layer of asphalt cement up to
45 cm (17.7 in.) deep in places covered an area of approximately 4000 m2 (1 acre). Besides the
physical hazard imposed by the asphalt cement, the primary contaminants of concern were PAHs,
which were a component of the asphalt cement. During May and June 1992, the asphalt cement,
barrels, approximately 2500 drums, 91,750 m3 (120,000 cu yd) of petroleum contaminated soil, and
other debris were removed. A layer of fill dirt approximately 2 m (6.6 ft) deep was placed over the
excavated area in June 1992. No record is shown for disposal activities at SS63.
7.8.1 Soil Contamination
The only soil contaminant to exceed EPA risk-based screening levels or background concentrations
at SS39 was DDT, as reported in Table 7.7. A summary of the sample concentrations for SS39 can be
found in Appendix A. Soil samples were collected from pits, soil borings, and ground surface soil and
analyzed for the constituents found in Table 5.12. Sample locations and diesel kerosene sampling
results are presented on Figures 7.11 through 7.14.

7.9 Source Area ST58
ST58, site of the old Quartermaster service station, is located on the northwest corner at the inter-
section of Division Street and Wabash Avenue (Figure 2.1). The service station covered approximately
400 m2 (478 yd2).
The Quartermaster service station was operated from 1970 to 1988. The service station was a
source of petroleum products for private vehicles operated by Eielson AFB personnel and their
dependents until 1975, and for Eielson AFB vehicles only after 1975. The service station used four
95-m3 (25,000-gal) above-ground storage tanks, containing leaded and unleaded motor gasoline
(MOGAS) and diesel. Two barrels of motor oil were stored at the service station for customer use.
Eielson AFB staff removed the above-ground storage tanks and above-ground piping in August
1988. Underground piping was left in place. During removal, workers noted evidence of product
releases. No analytical work was performed. The surface was covered with a meter (a yard) of fill
after the above-ground storage tanks and piping were removed (Liikala and Evans 1995). No spills
have been reported at ST58. However, the pipeline that supplied fuel to ST58 was suspected of leaking
at the intersection of Industrial Drive and Division Street, east of ST58. In 1993, approximately
532 cu m (700 cu yd) of fuel-contaminated soil was removed from the area most highly contaminated
for a composting demonstration and replaced with clean fill material.
Motor gasoline (MOGAS) and diesel stored and used at the Quartermaster service station appears
to have been spilled or leaked from the piping and diesel tanks. Some of the volatile components of
petroleum products released at the surface may have evaporated. The less volatile components
probably seeped into the soil. The less volatile contaminants may have adsorbed to the soils or been
dissolved in surface infiltration and carried to the groundwater. Fuel from large spills, if any occurred,
may have moved through the vadose zone and formed a floating layer on the water table. Because the
primary potential source of contamination (fuel storage tanks) has been removed, the potential source is
now any residual contamination in the soil that could be released to the groundwater. Additional
volatilization could occur, if the area is excavated.
Potential contaminants of concern are fuel-related organic compounds (BTEX) and lead. A variety
of laboratory analyses for geotechnical and chemical parameters have been performed using different
methods. Investigations of the site were carried out in 1991 (Shannon & Wilson 1991), in 1992
(Shannon & Wilson 1992), in 1993 (U.S. Air Force 1994b), and in 1994 (U.S. Air Force, 1995a,b,c).
Chemical analyses are summarized in Table 5.13.

7.9.1 Soil Contamination
Two soil-gas survey methods were used during June 1993 to identify heavily contaminated soil for
use in an ex situ remediation demonstration. Soil samples were collected from 17 test pits, using a
backhoe, and analyzed for VOCs, TPH-G, TPH-D, and lead.
The most contaminated soils were found in the central part of ST58 at the 1- to 1.7- and 2.7- to
3-m (4- to 5.5- and 9- to 10-ft) sampling intervals. Soils were contaminated with benzene and TPH
(gasoline) in significant concentrations, as shown in Table 7.8. This soil was subsequently excavated
for a composting demonstration. Significantly lower BTEX concentrations were found in the 0.1-m
(0.5-ft) samples (for example, benzene, 52 /*g/kg to detection limit). No chlorinated hydrocarbons
were detected in any of the samples (Liikala and Evans 1995).

Groundwater contaminants greater than EPA risk-based screening levels or background concentra-
tions for ST58 are summarized in Table 7.9. Groundwater samples were collected and analyzed for the
constituents listed in Table 5.13. A summary of the sample concentrations for ST58 can be found in
Appendix A and in Liikala and Evans (1995).
Investigations conducted during the fall of 1991 and winter of 1992 indicated that benzene
concentrations in the groundwater downgradient of source area ST58 were greater than the drinking
water standard. Toluene, ethylbenzene, and xylene were also detected.
In April 1993, groundwater samples were collected from the same wells. Benzene concentrations
above the drinking water standards were again found in several locations. Toluene and total xylenes
were also detected. Gasoline-range petroleum hydrocarbons at a concentration of 200 /ug/L were
detected in one well. Diesel-range petroleum hydrocarbons, ranging in concentrations from 0.1 to
99 /tg/L, were detected in 9 of 12 wells. Samples were analyzed for lead and it was found in
concentrations above the EPA action level (15 fig/L) in all of the source area wells.
A follow-on investigation was conducted in the fall of 1994. Lead and benzene concentrations in
the groundwater remain above the drinking water standard. The extent of benzene and lead
contamination is shown in Figures 7.15 and 7.16.
All contaminants detected at ST58 were in aqueous form. No floating product was encountered,
but it is likely that past fuel releases resulted in transient product plumes that have since dissipated after
the service station was closed and the buried supply pipeline removed from service.

7.10 Source Area SS64
SS64, the Transportation Maintenance Drum Storage Area, is located in the center of the developed
portion of the base, just north of the Water Treatment Plant pond on Garrison Slough, on the west side
of the Vehicle Maintenance Shop (Building 3213) (Figure 2.1). SS64 and an area south of Building
3213 (officially part of SS61) were used for an unspecified number of years as a storage and staging
area for drums containing hazardous materials and waste. Drums collected from routine base
operations and cleanup were stored at this area until they were shipped for disposal.
In 1986, the EPA found 550 208-L (55-gal) drums labeled methanol, paint waste, lacquer,
thinners, oils, acids, and asphalt at SS64. These drums were in poor condition and leaking. In 1987,
the EPA reported that additional drums had been brought to SS64 since the 1986 survey. Approxi-
mately 160 drums were labeled as paint materials, and 300 drums were labeled as solvents including
methyl ethyl ketone and cyclohexylamine. Six 322-L (85-gal) overpack drums were labeled as PD-680
solvent and paint thinner. Other inspection reports indicated that drums that were in other source areas
during previous compliance inspections had been transferred to SS64. In 1989, the approximately 900
drums from SS64 were disposed of by base Hazmat personnel. At that time, stained soils were
excavated and removed from SS64.
7.10.1 Soil Contamination
The drums stored at SS64 leaked and were the source of soil contamination. The locations of the
leaking drums are not known, but they are assumed to have been located randomly, each producing a
discontinuous spot of contamination. The contents of drums leaked onto the soil and then either
evaporated, leached into the subsurface via precipitation, or remained on the surface soils as stains. In
1989, the last drums were removed, eliminating that source. At that time, surface spills were cleaned
up, contaminated soil removed, and the area was graded and gravel added to prepare it as a parking
lot. Because of the graveling and grading activities at SS64, surface soil sampling was not performed.
Because contaminated soils were removed in 1989, subsurface soil sampling was not performed.
7.10.2 Groundwater Contamination
Groundwater contaminants greater than EPA risk-based screening levels or background concentra-
tions for SS64 are summarized in Table 7.10. Samples were collected and analyzed for the constituents
listed in Table 5.14. A summary of the sample concentrations for SS64 is presented in Appendix A.
The objective of the sampling was to check groundwater beneath the area where drums were stored
for constituents that were contained in the drums. Groundwater was sampled to determine if drum
contents reached the water table.

The only contaminants of concern that were detected were TCE, tetrachloroethene, and trans-
1,2-dichloroethene. These constituents were detected only in Well 64MW01, in the downgradient
position, at concentrations less than MCLs, but greater than the risk-based screening levels. Because
of the close proximity of SS61 where elevated concentrations of these constituents were detected, this
measurement may indicate that groundwater in this area is impacted by SS61.

8.0 Nature and Extent of Contamination at Operable Unit 5
This section discusses the nature and extent of groundwater and soil contamination at source areas
in Operable Unit 5 (OU 5). OU 5 includes LF02, LF03, LF04, and LF06, which are landfills. FT09,
a former fire-training area, is located on LF03 and included in OU 5.
8.1 Contaminants of Concern
The contamination detected and characterized at the OU 5 source areas is primarily a result of
land disposal practices. In addition, contamination caused by the burning of aviation fuels is present at
FT09. Contaminants of concern in groundwater at LF03/FT09 include the volatile organic compounds
(VOCs) benzene and vinyl chloride. Contaminants of concern in soil include total petroleum hydro-
carbons (TPHs) and polycyclic aromatic hydrocarbons (PAHs) resulting from the incomplete combus-
tion of fuel used in fire-training exercises. Contaminants of concern at LF02 and LF06 include
metallic and nonmetallic elements.
8.2 Source Area LF02
LF02 is an abandoned, approximately 6-acre (2.4 hectares) landfill located about 0.8 km (250 ft)
northwest of the intersection of Manchu Road and Gravel Haul Road on the banks of French Creek, a
tributary of Moose Creek (Figure 2.1). LF02 is about 122 m (133.4 yd) west of Bear Lake, a 370-m2
(3980-ft2) surface water body. A gravel road provides access from Gravel Haul Road. LF02
boundaries were located through a surface electromagnetic survey (HLA 1989). The minimum
distance from the site to French Creek is about 6 m (6.6 yd) (Figure 8.1).
LF02 was used as the primary base landfill from 1960 to 1967 and received domestic and base
operations waste. Refuse was burned from 1960 until 1964, when this practice was discontinued.
Burial of refuse continued until 1967, when the landfill was closed and capped. Capping material
included soil and fly ash from the base power plant. The cap was graded and has been maintained
since closure; it appears to be in good condition in the center of the landfill. At the edges, debris is
scattered on the surface, including miscellaneous household items, paper trash, metal and glass
fragments, scrap lumber, and construction debris. The area has been used as a snow removal disposal
area, and for at least 9 months of the year, a layer of scraped snow and ice overlies the cap. This snow
layer is piled 6- to 9-m (20- to 30-ft) deep on the margins of the landfill and somewhat less near the
center. During annual breakup, the snow melts and an unknown amount of water infiltrates the
landfill.

8.2.2 Groundwater Contamination
No groundwater contaminants were present in excess of EPA risk-based screening levels or
background concentrations. Groundwater samples have been collected and analyzed for the
constituents listed in Table 5.15. A summary of sample concentrations is presented in Appendix A.
8.3 Source Area LF03/FT09
LF03 is located east of the south end of the runway and north of the refueling loop (see Fig-
ure 2.1). FT09 is located within the west-central part of LF03. LF03 and FT09 are approximately
39.5 hectares (98.8 acres). LF03 was used as the main base landfill from 1967 to 1987. The landfill
received household garbage, scrap lumber and metal, construction debris, concrete slabs, empty cans
and drums from flightline industrial shops, and possibly waste oils, spent solvents, and paint residues
and thinners. The six trenches on the east side of the landfill received most of the waste after 1980.
The landfill excavation reportedly extended below the water table. The landfill boundaries were
established by geophysical surveys performed by HLA in 1988 and 1989. Potential sources of con-
tamination include the leaching of landfill debris by groundwater, and subsurface soil and groundwater
contamination by leaks from buried drums or cans. Because of the large number of potential
contaminant sources on a landfill, samples were analyzed for a variety of constituents, as shown on
Table 5.16.
Fire-training exercises at FT09 occurred from 1955 to 1989 and involved burning waste oils,
contaminated fuels, and spent solvents. Procedures used during the most recent exercises involved
saturating the ground with approximately 20,000 L of water, applying fuel, burning the fuel for
30 seconds, and extinguishing it with foam. A mixture of 2000 to 4000 L of clean JP-4 and up to
800 L of contaminated JP-4 was used in these exercises. Fire-training exercises were conducted at
least twice per month. Expected contaminants from FT09 include fuel-related compounds (BTEX) and
chlorinated solvents. The mock jet was removed in 1994. A new lined fire training facility is
currently under construction.
8.3.1 Soil Contamination
Soil contaminants greater than EPA risk-based screening levels or background concentrations for
LF03/FT09 are summarized in Table 8.1. A summary of sample concentrations for LF03/FT09 is
presented in Appendix A. Soil samples were collected and analyzed for the constituents listed in
Table 5.16.
Sample results delineated several areas of soil with TPH concentrations greater than 100 mg/kg.
An area of surface contamination approximately 30 by 60 m (98.4 by 196.9 ft) was delineated near a
mock-up jet fighter used for fire-training exercises. An area of subsurface contamination was identified
west of the mock-up jet, at a depth of approximately 1 to 2 m (3.3 to 6.6 ft) bis, which is just above
the water table. The subsurface TPH contamination may be the result of fire-training activities (such as
spilled fuel) or leakage from landfill debris.
As a result of the TPH survey, samples were collected adjacent to the former site of the mock-up
jet. PAHs were detected in all of these samples at concentrations ranging from 75 to 410 mg/kg. The
greatest number of PAHs was detected in surface soil sample 03SYS05, at the west end of the mock-up
jet. In addition, kerosene was detected in all but one sample. Naphthalene and 2-methylnaphthalene,

Sampling results, prior to 1994, indicated the presence of VOCs in groundwater at LF03/FT09 (see
Figure 8.2). Leakage from a subsurface JP-4 fuel pipeline approximately 76 m (83 yd) upgradient of
Well 03M13 had been cited as a possible source of benzene contamination; however, no toluene,
ethylbenzene, or xylene were detected in samples with the highest benzene concentrations. No floating
product was encountered. The presence of benzene without the other fuel-related VOCs is charac-
teristic of the leading edge of a plume from an upgradient source because benzene is more mobile than
the other constituents. Another possibility is the benzene plume may have originated from a source in
the fire-training area. Solvents were also detected in groundwater at LF03, prior to 1994.
Groundwater sampling results in 1989 delineated plumes of trichloroethane (TCE) near Well
03M08 and vinyl chloride near Well 03M01. TCE was not detected in samples collected downgradient
of Well 03M08 and, therefore, is probably caused by a localized leak from landfill debris. The plume
appeared to have originated near Well 03M01 and extended to the north, toward Garrison Slough.

These solvents were most likely derived from leaking containers of spent solvent in the landfill. Low
concentrations of solvents were also detected in the 1992 groundwater samples.
By the time of the sampling event in August 1994, benzene and chlorinated solvents were below
MCLs (and in many cases below detection limits) in all wells in LF03/FT09 and SS37, except for
Well 03M08 (see Figures 8.2 through 8.5). This well contained relatively high concentrations of a
number of contaminants (see Table 8.2), including 4-methyl phenol (p-cresol), dichlorodifluoromethane
(Freon-11), and trichlorofluoromethane (Freon-12). Analyses were not reported for Well 03M08 in a
previous investigation by HLA (1989) because of analytical difficulties. Well 03M08 was not sampled
in 1992. This well is located in the eastern portion of LF03 in the area of the waste trenches, which
were used after 1980.
Contaminated groundwater from LF03/FT09 has not migrated beyond the landfill boundaries.
8.4 Source Area LF04
LF04 is located approximately 5 km (3 mi) east-northeast of the south end of the runway (see
Figure 2.1) and covers an area of greater than 100,000 m2 (24.7 acres) (HLA 1989). LF04 reportedly
received general refuse, small quantities of waste oil and spent solvents, and possibly small amounts of
munitions and spent cartridges. A number of laboratory analyses were performed on groundwater and
soil samples from LF04. The Army originally used the site to store ammunition in bunkers. Access to
LF04 is currently restricted because of its designation as an emergency ordnance demolition area,
where small munitions are incinerated in a burning kettle. Geophysical surveys conducted by HLA in
1988 and 1989 established the approximate boundaries of the landfill.
No significant surface or subsurface contamination has been detected at LF04. Small areas of TPH
have been detected at concentrations of less than 250 mg/kg. No TNT or RDX compounds, resulting
from ordnance activities, have been detected. Under a separate federal program, the Air Force has
submitted a closure plan for the ordnance area at LF04 under RCRA, Section 3008(a).
8.5 Source Area LF06
LF06, the old landfill, is located near the central power plant just south of the power plant cooling
pond on the eastern side of the main developed portion of Eielson AFB (Figure 2.1). The landfill is
approximately 348 m (1000 ft) north of Hardfill Lake (Figure 8.6). From 1959 to 1963, LF06 was
used as a secondary landfill to the original base landfill (LF01, used in the 1950s) and the old base
landfill (LF02, used from 1960 to 1967). The landfill has been covered with a loose sand cover that is
maintained by periodic grading.
LF06 reportedly received large construction and metal debris and smaller quantities of general
refuse (such as wood, empty drums, and paint containers) from the flightline industrial shops (CH2M
Hill 1982). Because most of the base refuse would have been disposed at other sites, only small
quantities of waste paint, thinners, and spent solvents were assumed to have^been present as drum
residuals at LF06. Also, other liquid wastes, such as spent solvents, would likely have been disposed
only in 1959, because beginning in 1960, refuse disposed of in LF02 was first burned and then buried.
Therefore, only small quantities of these wastes are assumed to have been disposed in LF06.

9.0 Summary of Operable Unit Risks
9.1 Human Health Risks
The objective of the baseline risk assessment (BLRA) was to characterize the current and potential
threats to human health and the environment. The results helped establish remedial action objectives
necessary to develop remedial alternatives in the feasibility studies (National Contingency Plan 40 CFR
300). The BLRA evaluated risks at Eielson now and into the future. Consistent with EPA guidance,
the BLRA assumes that without cleanup measures, the identified source areas will remain in their
present states of contamination.
The Alaska Department of Environmental Conservation (ADEC), U.S. Air Force, and the U.S.
Environmental Protection Agency (EPA) have agreed to follow the guidelines for federal facilities
under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Super-
fund), 40 CFR Part 300, Section 120. The health risk assessments are based on the following EPA
guidance:
• Risk Assessment Guidance for Superfund, Volume 1, Human Health Evaluation Manual, Part A
(EPA 1989a)
• Exposure Factors Handbook (EPA 1989b)
• EPA Region 10 Supplemental Risk Assessment Guidance for Superfund (EPA 1991a)
• Standard Default Exposure Factors (EPA 1991b)
• Guidance on Risk Characterization for Risk Managers and Risk Assessors (EPA 1992).
9.1.1 Source Evaluation Report Areas
Contamination within the Source Evaluation Report (SER) sites, LF01, WP32, and DP55, was
analyzed by a conservative screening risk assessment that compared the maximum concentration of
each contaminant detected at the source area to a conservative risk-based concentration using EPA
standard default exposure factors for a residential scenario. The target risks used for the conservative
screening were chosen based on the lower end of the 10"4 to 10~6 risk range specified in the NCP. This
screening approach assumes that if no single sample exceeds a concentration representing a human
health risk concern, total exposure to the contaminant from the source area will not be of concern.
Based on this assumption, no further action is required for areas where maximum concentrations
detected were < 10'6 cancer risk for water, < 10'7 cancer risk for soil, and <0.1 hazard quotient. No
contamination at source areas LF01, WP32. or DP55 exceeded the screening levels; thus, further risk
assessment was not necessary for these SER areas.

9.1.2 Operable Unit 3, 4, and 5 Source Areas
As presented in the three previous sections of this ROD, the OUs were grouped according to their
use and the chemical contaminants detected:
• OU 3 -- cleaning and maintenance of equipment (DP44. WP45, ST56, SS61), refueling (SS57)
• OU 4 -- pesticide storage and mixing (SS35). mixing and storage of asphalt (SS35, SS36, SS37,
SS39/SS63, SS64), fuel tank farms (DP25. ST27). auto refueling (ST58), waste effluent ponds
(WP33)
• OU 5 - former landfill areas, including a fire-training area (LF02, LF03/FT09, LF04, LF06).
9.2 Site Data, Screening, and Identification of Contaminants of
Potential Concern
The environmental data used in the BLRA was collected in the CERCLA Remedial Investigation
and Feasibility Studies (Rl/FSs) (SAIC 1988. 19895; HLA 1989, 1990, 1991; U.S. Air Force
1993a,b,c). Fuel- and solvent-related organic chemical contamination of the groundwater and soil was
found at specific source areas that resulted from the dispensing or use of
• petroleum, oil, or lubricants
• industrial (cleaning) solvents (electronic and other equipment repair)
• paint products
• asphalt cement materials
• acids and bases (with storage batteries)
• other miscellaneous contaminants.
U.S. Air Force sampling results collected in 1991 and 1992 established background concentrations
for inorganic chemicals in soil and water media. The elevated concentrations of inorganic chemicals in
soil and water, including arsenic and manganese, are considered intrinsic in the Fairbanks region and
are not considered to relate to base activities. Nevertheless, risks were determined for all measured
chemicals that are not considered to be common laboratory contaminants (such as, acetone, chloro-
form, methylene chloride, and phthalates).
The BLRA used data collected in 1992 to 1994 for groundwater, and data from 1986 to 1994 for
soils and other media. Groundwater data collected before 1992 is not considered to be representative
of current conditions. Concentrations of contaminants in the soils are not believed to have changed
significantly between 1986 and 1994.
For some source areas and for several media, it was necessary to estimate chemical concentrations
using fate/transport modeling, either because samples were not collected or because concentrations at
September 1995 9.2 FINAL
-------
OUs 3, 4, and 5 Record of Decision Eielson AFB
points of human contact (exposure) were not available. For example, specific chemicals in garden
vegetables were not measured, but have been estimated from appropriate soil concentration data.
Table 9.1 lists all contaminants of potential concern that were analyzed with the mean, maximum,
and reasonable maximum exposure (RME) concentrations that were used in the assessment. Data
provided in Table 9.1 include the values taken as half the detection limits. The RME value is either the
upper 95th confidence interval (CI) of the mean or the maximum value, if the CI exceeded the maxi-
mum concentration value. If measured concentration data were not available, the RME values were
estimated using modeling, as described in the BLRA. The RME value was used in the BLRA to esti-
mate human intake of contaminants for risk assessment. The exposure point concentration (the upper
95th confidence interval on the mean or the maximum value, as appropriate) is the maximum concen-
tration value that is expected for human contact.
All positively identified chemicals were screened to determine whether their concentrations and
toxicity potentials exceeded EPA-established risk levels (EPA 1991b). Any chemicals with maximum
concentrations that triggered cancer risk levels greater than one in 10"6 for water or one in 10"7 for
soils, or noncancer hazard quotients (HQs) greater than 0.1 are presented in Tables 9.2a and 9.2b.
Screening levels were set below toxicity thresholds to ensure the combined actions of chemicals are
neither excluded in the calculations nor underestimated in the determination of net adverse health
potentials in humans.
The chemicals of potential concern that result from the screening by source area and media are
presented in Table 9.2a for carcinogens and Table 9.2b for noncarcinogens. The classes of chemicals
detected in OUs 3, 4, and 5 were fuel-related [benzene, toluene, ethylbenzene, and xylene (BTEX),
kerosene, and lead]; residuals from asphalt paving [kerosene, polycyclic aromatic hydrocarbons
(PAHs)]; pesticides; chlorinated cleaning solvents; and paint-related compounds.
The screening process described previously allowed for identification of contaminants of concern
above the EPA-established risk levels. This screening process was not used, however, to limit the
number of contaminants carried through the quantified risk assessment; all of the contaminants listed in
Table 9.1 as contaminants of potential concern were retained for further risk evaluation. All data was
available in electronic form; therefore, it was a more straightforward process to run all data through
the computerized spread sheets than to revise the database and remove contaminants that do not
contribute significantly to the total risk.
9.3 Exposure Assessment
9.3.1 Conceptual Site Model
An exposure assessment evaluates the potential for human contact with chemicals of concern
present at, or migrating from, a source area. At Eielson, human exposures occur as a result of contact
with organic chemicals (including pesticides, asphalt, and fuel mixtures) and inorganic chemicals.
The goal of the assessment is to appropriately combine the exposure point concentrations with land
use/population scenarios to calculate chemical intake or dose due to human contact with contaminants.
The calculated doses were then combined with toxicity data to characterize health risks.
FINAL 9.3 • September 1995
-------
Eielson AFB OUs 3, 4, and 5 Record of Decision
Chemicals may migrate along pathways from sources to points of human contact (such as expo-
sure). Included as part of the pathway assessment are the contaminant sources, the environmental
media (such as soils, groundwater, and air), the routes of contact (such as oral ingestion, dermal con-
tact, and inhalation), and the contact itself. If contact is not made, exposure does not occur and the
pathway is not complete. The completed pathways of concern at specific source areas within the OUs
were evaluated quantitatively to provide numerical estimates of potential exposures, which were then
used to .estimate human health risks.
The exposure cases or scenarios evaluated for a given source area depend on the populations
potentially exposed and on the current and potential land use at Eielson. In this assessment, a
residential scenario is evaluated to consider potentially exposed future users who could spend 30 years
on-site. This scenario, which includes children, who may be the most sensitive subpopulation to be
exposed, is generally the most conservative case. The residential exposure scenario is evaluated for
OUs 3,4, and 5 to determine potential risks in the unexpected event of base closure. The current land
use as a military base is not expected to change in the foreseeable future. Other populations of concern
are current military and civilian workers; and commercial workers who could be exposed in the future,
if the base is converted to civilian use.
The conceptual model of pathways and exposures evaluated for current use, future use, and
recreational scenarios is outlined in Figure 9.1.
9.3.2 Exposure Factors
To ensure consistency in the risk assessment process, the EPA's Superfund program has developed
standard default exposure factors for selected exposure pathways. Standard default factors are con-
sidered the most appropriate exposure parameter values for risk calculations, and EPA stipulates they
should be used in BLRAs, unless alternate or site-specific values are clearly justified by supporting data
(EPA 1991a, 1991b). The rationale for each standard default value is discussed in Human Health
Evaluation Manual, Supplemental Guidance: Standard Default Exposure Factors (EPA 1991a), and the
values are listed in Region X guidance (EPA 1991b). However, the Eielson location near the Arctic
Circle required the use of site-specific factors to compensate for extended periods with snow cover and
frozen ground. In addition, to accommodate a possible subsistence lifestyle, the assessment considered
the ingestion of fish caught adjacent to two source areas (SS35 and SS37), vegetables potentially grown
at the source areas evaluated for future residential use, and other site-specific parameters. Table 9.3
lists both the EPA default and the Eielson site-specific exposure factors used in the assessment. When
the exposure factors are applied to standard risk equations, intake factors are calculated; the table
includes these results. When the intake factor is multiplied by exposure point concentrations, a dose is
calculated. Specific doses are used with toxicity factors (for each chemical) to estimate human health
risk.
Chronic exposure periods (9-, 12-, 25-, or 30-year durations) that typify high-end recreational and
average residential and worker exposures provide information for assessing human cancer risks and
other chronic adverse effects. Cancer risks are considered for 70-year lifetimes. A 3-year exposure
period is used for the current at-risk child in a recreational setting, and a 6-year exposure period is
used for a child in a residential setting. These periods are consistent with the typical on-base stay of
military personnel and dependents. At the levels of contamination existing in the source areas, acute
poisoning and other short-term effects are considered unlikely.
The potential current- and future-use exposures assume above-average intake of contaminants that
are used to calculate chemical (contaminant) intake by humans. Whether the contaminants are

measured from field sampling data or estimated using fate/transport modeling, the upper 95th con-
fidence limit on mean (Gilbert 1987) RME concentrations represents conservative exposures expected
for a site under current or future conditions. Non-detect values were assigned a concentration of one-
half the detection limit (EPA 1991b) and future-use exposures were based on the surface soil or the
subsurface soil RME, whichever is larger.
9.4 Evaluation of Lead Contamination
Lead contamination was identified at source areas DP25, ST27, and ST58. Source area DP25 is
the E-6 Fuel Storage Tank area, ST27 is a fuel-storage tank farm, and ST58 is the site of the old
Quartermaster Service Station, which has been removed.
Exposure to inorganic lead is treated separately from other contaminants for purposes of deter-
mining protective levels. In July 1994, EPA issued OSWER Directive # 9355.4-12, Revised Interim
Soil Lead Guidance for CERCLA Sites and RCRA Corrective Action Facilities to establish an approach
to determine protective levels for lead in soil. This directive identifies the Integrated Exposure Uptake
Biokinetics (IEUBK) model as the most appropriate and applicable method for assessing and managing
risks from lead in soils (Bennett 1990; EPA 1991c, 1994a).
The EPA guidance set residential and industrial screening levels for lead at 400 mg/kg and
1000 mg/kg, respectively. The screening level serves as an indicator that additional study may be
appropriate. With the exception of one soil sample in 1986 of 870 mg/kg at DP25, the E-6 Fuel
Storage Area, soil lead levels found at all sites reviewed at Eielson AFB are below the 400 mg/kg
screening level. The E-6 Fuel Storage Area is an industrial area and lead levels do not exceed the
industrial screening level. No further study is necessary, given that special circumstances are absent.
Presently, no MCL exists for lead. In lieu of an MCL, EPA has established a lead action level of
15 ng/L for water. Groundwater lead levels found at the sites reviewed at Eielson AFB were com-
pared to this action level. Based on this screening, lead was identified as a contaminant of concern in
groundwater for source areas DP25, ST27, and ST58.
9.5 Toxicity Assessment
Where available, the EPA-authorized chemical-specific toxicity factors are the reference values
used to express cancer risk levels and nohcancer effects. The available factors, listed in Integrated
Risk Information System (IRIS) and Health Effects Assessment Summary Tables (HEAST), have been
corrected for exposure times, animal-to-man extrapolations, and others. Potential cancer risks are
quantified through the use of dose-response slope factors. The cancer potency or risk is characterized
as an upper-bound estimate, meaning the true risk to humans is not likely to exceed the estimate and
may even be lower (EPA 1989a). The reference dose (RfD) is used to evaluate toxic effects from
noncarcinogens and estimates the maximum daily exposure to human populations that is not likely to
result in an appreciable risk of adverse effects. The critical toxicity values used for the major
20 contaminants of concern are shown in Table 9.4a. Table 9.4b shows the additional toxicity factors
that were needed in the risk assessment for screening of chemicals and risk quantification.

The carcinogenic risk from exposure to a chemical is described in terms of the probability that an
exposed individual will develop cancer over a lifetime. This value is a function of the estimated
chronic daily intake (dose) and the slope factor for the chemical. The slope factor converts the
estimated dose, averaged over a 70-year lifetime of exposure, to a risk for an individual (EPA 1989a):
Cancer risk = Dose x SF (9.1)
where
risk = n excess probability (such as 2 x 10'3) of an individual developing cancer as a
consequence of chronic exposure
Dose = chronic daily intake averaged over 70 years, in mg/kg • day
SF = slope factor, in mg/kg • day
The estimated carcinogenic risks from each contaminant and pathway are added to determine total
additional risk resulting from site-specific contamination. This additional risk is above the rate of
cancer in the United States from all causes which is estimated to be as high as 1 in 4. The National
Contingency Plan (40 CFR 300) defines acceptable risk from Superfund site as additional cancers due
to site-specific contamination in the range of 1 chance in 10,000 (1 x 10"") to 1 chance in 1,000,000
(1 x 10'6).
The risk of noncarcinogenic effects from contaminant exposure is expressed in terms of the hazard
quotient (HQ). The HQ is the ratio of the estimated average daily dose (ADD) (for an appropriate
period of exposure) to the RfD. The HQ for chronic effects is expressed by the following equation:
HQ = ADD/RfD (9.2)
where
ADD = average daily dose (in mg/kg • day)
RfD = reference dose for chronic exposure (in mg/kg • day).
An HQ that is greater than 1.0 indicates a potential for adverse health effects. Although the
incidence or severity of those effects is likely to increase as the HQ increases, the dose-response rates
can differ among contaminants and health effects. Thus, an HQ value of 1.0 does not define a sharp
distinction between no effects and adverse effects, but rather a transition to the potential for adverse
effects.
Exposures to a single contaminant from different pathways, or exposures to multiple contaminants,
can act cumulatively to produce adverse health effects, even if all individual exposures are below RfD
values. Therefore, a hazard index is calculated by summing HQs across contaminants and pathways.
A hazard index that exceeds 1.0 indicates a potential for adverse health effects, under the assumption
that risks are additive across chemicals and pathways.

A summary of cancer risks and noncancer effects is found in Table 9.5. For each source area, the
summary table shows the probable cancer risks that are expected to be greater than a rate of 1 in
1,000,000 or noncarcinogenic effects with a HI greater than 0.1. In these tables, organic and inorganic
chemical risks have been summed, according to EPA guidance (EPA 1989a).
A breakdown of the routes of contaminant intake, the environmental media, the chemical, and the
corresponding risk or effect level for all positively identified chemicals is shown in Tables 9.2a and
9.2b. These tables identify the contaminants of concern for each pathway along with its corresponding
.risks. The cumulative risks presented in Table 9.5 are somewhat higher than the cumulative risks
presented in Tables 9.2a and 9.2b, which include only positively identified contaminants, because all
contaminants analyzed are included in Table 9.5, regardless of whether they were detected. In Table
9.5, nondetect values were assigned a concentration of one-half the detection limit (EPA 1991b) and
future use exposures were based on the surface soil or the subsurface soil RME, whichever is larger.
.Cancer risks: In OU 3, the cancer risks at source area DP44 shown in Table 9.2a result from soil
exposure to benzo(b)fluoranthene, benzo(a)anthracene, and dibenzo(a,h)anthracene, while groundwater
exposure results from contact with trichloroethane. Benzene in the groundwater is the major contri-
butor at SS57. At SS61, pentachlorophenol, trichloroethane, and gasoline are the risk contributors.
In OU 4, exposure to the groundwater via ingestion and inhalation arise from contact with benzene.
At source area SS35, dermal exposure to DDT drives risks. The inadvertent ingestion and inhalation
of traces of gasoline in the groundwater at ST58 provides elevated cancer risk probability.
At OU 5, 1,1-dichloroethylene, vinyl chloride, 1,4-dichl.orobenzene, and trichloroethane may
result in cancer risk from exposure to soil and groundwater media at LF03.
Noncancer risks: Table 9.2b shows noncancer risks that metals contribute are most of the
noncancer risks at Eielson AFB. However, because they are assumed to be at background levels and
not from Eielson sources, inorganic chemical are not considered as risk drivers. With the exception of
DDT at source area SS35, all of the following noncancer OU 3, 4, and 5 exposures result from use of
the groundwater.
In OU 3 at DP44, trichloroethane may cause adverse effects from drinking the groundwater. At
WP45, ingestion of trichloroethane in the groundwater may cause ill effects. At SS57, toluene is the
major contributor to noncancer effects. At SS61, trichloroethane contributes the bulk of the
contaminant load.
For OU 4, the DDT levels at SS35 approach a HQ of 1 to become the major risk source.
At the OU 5 source area LF03, the major organics, trichloroethane and tetrachloroethylene, sum to
less than 1.
9.7 Uncertainty Evaluation for the Human Health Risk Assessment
The calculated exposures and risks are based on numerous assumptions and parameter estimates
that are themselves uncertain. These uncertainties affect both exposure estimates and toxicity values.
Overall, the calculated exposures and upper-bound risks for the defined adverse effects are unlikely to
result in underestimates; however, true risks could be lower than those calculated. Some assumptions
and uncertainty factors associated with the BLRA include the following:
FINAL 9.7 September 1995

Eielson AFB OUs 3, 4, and 5 Record of Decision
> The numerical estimates, based on standard EPA default and site-specific exposure factors for
potential exposure and risk development for a quantitative risk assessment, cannot be precise
values. Therefore, the uncertainty in the risk estimates is an important consideration, particularly
for the Eielson sub-Arctic climate. Some risks, based on standard defaults, may be overestimated,
despite compensation for location-specific factors.
The baseline risk assessment presumes media concentration will prevail over time at their current
levels. This assumption does not account for any natural biodegradation of contaminants with
time. At LF03, most recent contaminant concentrations are considerably lower than the previously
measured values. In this instance, it is likely that groundwater risks have been overestimated.
Conversely, if the groundwater contaminant concentrations increase in the future due to additional
leaching from a remaining source, the groundwater risks may be underestimated.
' At WP45, the maximum TCE concentration in groundwater has not been confirmed on resampling.
This could be due to the disposal of snow on the area, resulting in the dispersal and dilution of
groundwater TCE. Therefore, this value was not included in the risk assessment. If the value was
included, the risk at WP45 due to TCE in groundwater would be 8E-4, doubling the total risk at
WP45/SS57.
• Several of the basic assumptions used to develop appropriate exposure scenarios at Eielson AFB
have little or no uncertainty associated with them. The existence of elevated concentrations of
some contaminants within the various source areas is not in question, because these contaminants
have consistently appeared in sampling studies, including data collected since 1986. Also, little
uncertainty exists that specific source areas are contaminated by mixtures of aviation and motor
fuels, cleaning solvents, and pesticides, even if the full extent of the contributions of each chemical
is not completely defined. The primary land use in the source areas is military/commercial, a fact
not expected to change in the foreseeable future (unless the base is closed). As a result, a worker
exposure scenario is considered highly appropriate for current and future risk characterization at
Eielson AFB.
• Exposures and risks to individuals (at a given source area) will differ because of different
behavioral patterns, or genetic differences and sensitivity among individuals. Consequently, in
addition to the uncertainty associated with a given estimate of risk for a particular population
group, an underlying distribution will be present (on the risk level) that reflects alternative poten-
tially exposed populations.
• Exposure point concentrations are reasonably certain for measured data. However, concentration
data for sediments, surface water, and fish (for locations and chemicals not sampled in 1994) were
modeled. The modeled data may be uncertain; for the Eielson region, it is difficult without site-
specific fate/transport data to judge whether the resulting exposure point concentrations
overestimate or underestimate risks.
• The background sampling for metals is thought sufficient to show that, with the exception of lead,
these metals did not result from Air Force activities. For example, considerable information exists
to verify that arsenic, which occurs at elevated concentrations throughout the region, is responsible
for elevated risk rates, near Fairbanks from the ingestion of groundwater. Sources of lead have
been identified on the base; unfiltered lead concentrations were used to for comparison to current
action levels.
• Toxicity factors associated with the 20 risk-driver chemicals shown in Table 9.6 are based on
scientific information with measurable uncertainty. In contrast, many of the other toxicity factors
used in the screening process have an unknown degree of uncertainty. Most of the carcinogenic
September 1995 9.8 FINAL
-------
OUs 3, 4, and 5 Record of Decision Eielson AFB
chemicals considered to be risk drivers are class A (sufficient evidence of carcinogenicity in
humans), B (probable evidence), or C (limited evidence for humans). The uncertainty associated
with the risk driver chemicals is not considered to either overestimate or underestimate risks.
• Some uncertainty may exist in the determination of the risks associated with human exposure to
fuels. Although total petroleum hydrocarbons (TPHs) were measured, their risk was not estimated
because they are fuel mixtures and not pure chemicals. Consequently, they lack the toxicity factors
needed for risk analyses. Usually the BTEX chemicals (benzene, toluene, ethylbenzene, and
xylene) are considered surrogates for TPHs, thus allowing for the estimation of fuel-related risks.
The EPA has estimated preliminary factors for the gasoline, diesel, kerosene, and jet fuel mixtures, .
but these factors may not be applicable to the weathered fuel frequently found at Eielson AFB.
Even though these preliminary factors have been withdrawn, they were used in the assessment.
Surrogate and preliminary data that do not necessarily apply to the contamination found at Eielson
Air Force Base were used to calculate fuel-related risks; this may result in overestimated or
underestimated risks.
9.8 Environmental Risks
Table 9.6 summarizes the terrestrial habitat types and their primary wildlife species on Eielson
AFB.
No endangered or threatened species are resident to Eielson AFB. The American peregrine falcon
(federally endangered) breeds within 50 miles of the base and the Arctic peregrine falcon (federally
threatened) migrates to within 50 miles of the base. Bald eagles (federally threatened) are occasionally
sighted on Eielson AFB.
No acute ecological risks were identified for source areas in Operable Units 3, 4, or 5. With the
exception of SS35, the Asphalt Mixing and Drum Burial area, these areas do not appear to be acting as
sources of surface water or sediment contamination. PCBs and pesticides, particularly DDT, were
found in soil at source area SS35, which is located adjacent to Garrison Slough. Elevated body
burdens of DDT were found in fish caught near SS35. Cumulative ecological risks at Eielson AFB are
currently being evaluated under the Sitewide program. Preliminary conclusions indicate that SS35 may
present reproductive risks to birds and mammals from ingestion exposure to PCBs and DDT. The
Sitewide biological risk assessment addresses ecological risks from all areas on base.
9.9 Summary of Source Area Disposition
The nature and extent of contamination and its corresponding risk, as well as the potential future
use of a given source area, were evaluated to determine which source areas required development of
cleanup alternatives in the Feasibility Study. A summary of the dispositions for source areas is
presented in Table 9.7.

(a) The value 70 is used to calculate the intake term for the 70-year cancer case; other values are used for the noncancer exposures.
(b) Intake factors multiplied times exposure point concentration terms yield dose for risk characterization. Units for intake factors are kg/kg-day (soils, sediments, soil
particles, vegetables and fish), L/kg-day (groundwater and surface water), and m'/kg-day (volatile chemicals from the groundwater and surface water).
(c) NA = not applicable.
(d) The inhalation of groundwater volatiles is daily, not only, for bathing or showering.
Note: A chemical-specific permeability factor is needed to calculate intake for dermal contact with surface water and groundwater.

10.0 Description of Alternatives-OU 3
This section provides a concise description of the remedial action objectives and remedial alter-
natives evaluated for each source area in OU 3. The feasibility study (FS) provides information on the
assumptions and calculations used in the development of the alternatives and the cost estimates for the
alternatives.
10.1 Remedial Action Objectives
Remedial action objectives (RAOs) were developed to specify actions and contaminant levels
necessary to protect human health and the environment. RAOs define the contaminants of concern,
exposure routes and receptors, and remediation levels, which are defined as acceptable contaminant
levels for each exposure route. The primary RAO is protection of groundwater.
The RAOs for the source areas within OU 3 are:
• At DP44, prevent the continued migration of TCE into the groundwater at concentrations that
present a risk to potential future groundwater users.
• At WP45/SS57, prevent the continued migration of TCE and benzene into the groundwater at
concentrations that present a risk to future groundwater users. Subsequent sampling indicates
that little contamination remains in the unsaturated zone (see Section 16).
• At ST56, supply drinking water, apply wellhead treatment, as applicable, prevent use of
groundwater that exceeds state or federal drinking water standards.
• At SS61, determine if an additional source of contaminants exists on the north side of the
building and if so, prevent the continued migration of TCE into the groundwater at
concentrations that present a risk to future groundwater users.
• At all source areas, prevent human exposure to groundwater contaminated above the drinking
water standards and restore the beneficial uses of the aquifer.
The goal of the Superfund approach is to return usable groundwaters to their beneficial uses within
a timeframe that is reasonable, given the particular circumstances of the site. Reasonable restoration
time periods may range from very rapid (one to five years) to relatively extended (several decades).
Location, proximity to population, anticipated future land use, and mobility of the contaminant plume
are factors considered when determining an appropriate restoration timeframe.
The use of: (1) natural attenuation with institutional controls, (2) source reduction through treating
soil contamination to prevent additional contaminant leaching into the groundwater, and (3) ground-
water pumping and treating were considered viable options for addressing groundwater contamination
at Eielson AFB. For source areas within OUs 3,4, and 5, the following site specific conditions were
considered when determining reasonable restoration timeframes:
• Contaminant plumes in this relatively homogeneous aquifer do not appear to be spreading or
are decreasing in size.
FINAL 10.1 September 1995
-------
Eielson AFB Oils 3, 4, and 5 Record of Decision
• Biodegradation, dispersion, dilution, or adsorption appear to be effectively containing or
reducing the size of the contaminant plume.
• Areas impacted by the contamination are relatively small with little likelihood of extended
exposure to groundwater anticipated.
• Future land use as a military installation is not anticipated to change in the foreseeable future.
10.2 Remedial Action Components
The sources areas comprising OU 3 (DP44, WP45/SS57, ST56, and SS61) contain groundwater
and soils contaminated with VOCs, SVOCs, and metals. Subsurface treatment of the groundwater at
ST56 was not evaluated in the FS because of the complex hydrogeology of the fractured bedrock; the
limited extent of the contamination in a remote, restricted area of the base; and the reliability of
available institutional controls to restrict the use of the contaminated water. The alternatives to address
the remaining source areas are assembled from one or more of the following remedial action
components:
• No Action
Components to Address Groundwater Contamination
• Institutional Control and Groundwater Monitoring
• Groundwater Extraction and Treatment
Components to Address Soil Contamination
• Soil Vapor Extraction (SVE)/Bioventing
• Soil Excavation
The no action alternative does not address the RAOs established for each source area. It represents
the baseline risk without institutional controls or active remediation. The institutional controls and
groundwater monitoring alternative prevents the use of contaminated groundwater, but does not include
active remediation. The other components provide a range of control with varying timeframes to
achieve the RAOs. Because it is difficult to remove all of the residual contamination and to reduce
groundwater contaminant concentrations below state and federal water quality standards, even with
groundwater extraction and treatment, it is expected that all of the alternatives would require long-term
management of the area.
The five remedial action components are described in the following paragraphs. Following this
discussion, the components are assembled into remedial action alternatives for each of the source areas.
Cost for the alternative for each source area is included in Table 10.1.
10.2.1 No Action
Under this approach, no action is taken to remove contaminants from the soils or the groundwater.
Evaluation of the no action approach is required by the NCP to provide a baseline against which other
alternatives can be compared. Under the no action alternative, no remedial measures are implemented

standards. Specific controls include restrictions limiting access to the source areas and administrative
controls to limit groundwater and future land use. Access restrictions, including such measures as
permanent markers, are used to prevent direct human exposure to contaminants. Groundwater restric-
tions are implemented by placing written notification in base policies prohibiting the use of con-
taminated groundwater. In addition, all existing and any new wells located in or near the contaminated
portion of the aquifer shall be locked to prevent unauthorized use.
The administrative controls for limiting future land use include placing written notification of these
remedial actions in the base land use master plan. The notification shall prohibit any activity that
disrupts aspects of the engineered controls. A copy of the notification is provided to any prospective
transferees of the property and is included in any transfer documents, including deeds, in the event that
the Air Force released control of the affected property. The Air Force shall provide EPA and the state
with written verification that notification(s) have been implemented.
10.2.3 Groundwater Extraction and Treatment
Groundwater extraction was evaluated for source areas DP44, WP45/SS57, and SS61 as a way to
potentially accelerate aquifer restoration. The number and location of extraction wells, as well as
estimated times to achieve cleanup, are discussed in Sections 10.3, 10.4, and 10.5.
VOCs and SVOCs in the extracted groundwater would be removed using physical/chemical treat-
ment, such as air stripping and activated carbon. Due to the high metals levels naturally found in the
groundwater at Eielson AFB, metals removal may be necessary prior to treating the water for site-
specific contamination. The need for air emission controls would be evaluated and implemented in
accordance with the Clean Air Act (42 USC 7401). Treated groundwater would be discharged to
Garrison Slough in accordance with federal ambient water quality criteria, 18 AAC 70, and
18 AAC 72.
10.2.4 Soil Vapor Extraction/Bioventing
A combination of SVE and/or bioventing was evaluated for source areas DP44 and WP45/SS57.
This alternative enhances bioremediation and volatilization of contamination in the vadose zone for
SVE/bioventing and in the smear zone for bioventing. For WP45/SS57, the system could be operated
in the air injection or air withdrawal mode with wells screened across the water table. Although air
emission controls would be installed in accordance with the Clean Air Act, if needed, the system would
be designed and operated to minimize the need for air emission controls.
Based on assumed contaminant concentrations and expected removal rates, it is estimated the SVE
system would operate from 1 to 3 years (6 months/year) to meet soil RAOs for TCE and related
compounds in the vadose zone. SVE may be enhanced with air injection or capping. For bioventing,
estimates of treatment times are provided in specific alternatives incorporating this component.
10.2.5 Soil Excavation
Excavation of contaminated soil from source areas WP45/SS57 and SS61 and out-of-state disposal
was evaluated. Soil excavation would be conducted during one summer construction season. Con-
taminated soils would be removed from the ground surface to the top of the saturated zone. Using a
field screening technique, clean soils would be segregated from contaminated soils. The excavated area
would then be backfilled with clean material.

10.3 Source Area DP44
Site conditions of source area DP44 followed by the remedial action alternatives are discussed in
this section.
10.3.1 Site Conditions
The primary concern at source area DP44 is TCE in the groundwater. However,
tetrachloroethylene, benzene, and cis-l,2-DCE (a TCE breakdown product) were also found in the
groundwater. In addition, TCE was found in the subsurface soil along the edge of and beneath the
tarmac south of the Hangar (Building 1140).
The primary potential exposure pathway for source area DP44 is from the future unrestricted use of
contaminated groundwater. Therefore, contaminants in groundwater and the risk from continued
leaching of contaminants to groundwater are of primary concern.
10.3.2 Remedial Alternatives
Four alternatives have been developed to address the contaminated soil and groundwater at source
areaDP44. The four alternatives are listed in Table 10.2.
A description has been developed for each of the four alternatives identified for source area DP44.
The descriptions identify the technologies, describe the representative process options, and present the
assumptions that provide the basis for the analyses of the alternatives.

Alternative 2—Institutional Controls/Groundwater Monitoring
This alternative is a limited action alternative consisting of two components.
Based on currently observed concentrations in the soil and groundwater, it was estimated that TCE
may continue to leach into groundwater for more than 10 years. Trichloroethane-contaminated soils
could continue to act as a contaminant source to groundwater, especially during periods of snow melt.

Eielson AFB OUs 3, 4, and 5 Record of Decision
Within the groundwater, biodegradation, dispersion, dilution, and adsorption appear to be effectively
containing and degrading the contamination. Because of this continuing source of release and the
probability that groundwater concentrations will remain above federal and state standards for an
extended period of time, a long-term groundwater monitoring program and institutional controls are
included as part of this alternative.
Institutional controls and groundwater monitoring would be implemented, as discussed in Sec-
tion 10.2.2, to restrict groundwater use, prevent human exposure to contaminants at concentrations
above state and federal standards, and maintain an accurate definition of the area of contamination.
Alternative 3-SVE
The SVE alternative includes the following remedial action components.
Under this alternative, SVE would be used to reduce the concentrations of TCE in the subsurface
soils along the edge of the runway on the southeast side of Hanger 1140. This area is the suspected
source of the TCE contamination found in groundwater at nearby Well 44M04. It is assumed that
approximately six vertical extraction wells on a 18.3-m (60-ft) spacing would be installed to remove
contaminated soil vapor from the assumed 76- to 84-m (250- by 275-ft) target area.
Seven passive air injection wells were assumed to be installed below the surface of the existing
tarmac to provide improved air flow through the vadose zone, and to prevent short-circuiting from the
southern edge of the target area. Due to the relatively short distance from the surface to the con-
taminated vadose zone, and the narrow zone of contamination, a portion of the unpaved target area
would be capped as part of the operation.
The groundwater would not be actively remediated. The contaminants would be allowed to
disperse and degrade naturally. Within the groundwater, biodegradation, dispersion, dilution, and
adsorption appear to be effectively containing and degrading the contamination. If a significant volume
of TCE is remaining in the vadose zone, the natural attenuation of the TCE in groundwater would
benefit from the remedial activities designed to address the contaminant source.
The TCE in the vadose zone would be removed through SVE, and the chlorinated VOCs in
groundwater would be allowed to attenuate through natural processes. The continuing source from the
vadose zone soil will be treated by SVE in 1 to 3 years. Because it is probable that groundwater
concentrations will remain above federal and state standards for an extended period of time, a long-
term groundwater monitoring program and institutional controls was included as part of this
alternative.
Institutional controls and groundwater monitoring would be implemented, as discussed in Sec-
tion 10.2.2, to restrict groundwater use, prevent human exposure to contaminants at concentrations
above state and federal standards, and maintain an accurate definition of the area of contamination.
Alternative 4-SVE/Extract
The SVE/Extract alternative includes the following remedial action components:

Groundwater Extraction and Treatment. These actions would be implemented in an attempt to
accelerate aquifer restoration. A single groundwater extraction well would be operated at 30 gpm to
increase the speed of aquifer restoration. Extracted groundwater will be treated as discussed in
Section 10.2.3.
Based on modeling projections, the groundwater extraction and treatment system proposed under
this alternative would need to operate for at least 10 years. Year-round operation is assumed.
The TCE in the vadose zone would be removed through SVE, and the chlorinated VOCs in
groundwater would be reduced through extraction.
The continuing source from the vadose zone soil will be treated by SVE in 1 to 3 years. Because it
is probable that groundwater concentrations will remain above federal and state standards for an
extended period, a groundwater monitoring program and institutional controls was included as part of
this alternative.
Institutional controls and groundwater monitoring would be implemented, as discussed in Sec-
tion 10.2.2 and Alternative 3, to restrict groundwater use, prevent human exposure to contaminants at
concentrations above federal and state standards, and maintain an accurate definition of the area of
contamination.
10.4 Source Area WP45/SS57
10.4.1 Site Conditions
The primary concern at source area WP45/SS57 is the presence in groundwater of TCE and
benzene above drinking water standards. However, a breakdown product of TCE, as-l,2-DCE, and
tetrachloroethylene (PCE) were also found in the groundwater. TCE was found in the subsurface soils
at Well 45M08.
The primary potential exposure pathway for source area WP45/SS57 is from the future unrestricted
use of contaminated groundwater. Therefore, contaminants in groundwater and the risk from
continued leaching of contaminants to groundwater are of primary concern.
10.4.2 Remedial Alternatives
Six alternatives have been developed to address both the contaminated soil and groundwater at
source area WP45/SS57. The six alternatives are listed in Table 10.3.
A description has been developed for each of the six alternatives identified for source
areas WP45/SS57. The descriptions identify the technologies, describe the representative process
options, and present assumptions that provide the basis for analyses of the alternatives.

This alternative is a limited action alternative. No action will be taken for subsurface soil.
primary components are briefly outlined in the following paragraphs.
The
Institutional controls and groundwater monitoring would be implemented, as discussed in Section
10.2.2, to restrict groundwater use, prevent human exposure to contaminants at concentrations above
federal and state standards, and maintain an accurate definition of the area of contamination. Fire well
C is located in the middle of the TCE plume, but only trace concentrations of DCE have been detected
in the well. The well is connected to the potable water supply on base and a slight chance exists that it
could introduce solvent contamination into the water supply. Institutional controls also apply to use of
this well to prevent using the contaminated groundwater in a manner that would pose an unacceptable
risk to human health and the environment.
Results of a recent Utah Water Research Laboratory (UWRL) study at WP45/SS57 concluded that
the remaining source of TCE contamination is predicted to be exhausted in approximately 7 years. No
evidence is present of residual dense non-aqueous phase liquid (DNAPL) and it also does not appear
that any residual fuel material exists in the form of light non-aqueous phase liquid (LNAPL). The
contamination is adsorbed and contained or is in a dissolved phase and not readily accessible for source
removal or treatment. The data indicate that natural processes are expected to achieve remediation
within the same relative timeframe as that predicted for active remediation.
Within the groundwater, biodegradation, dispersion, dilution, and adsorption appear to be
effectively containing and degrading the contamination. Because of the continuing source of release
and because groundwater concentrations are currently above state and federal standards and are
expected to remain at those levels for an extended period of time, a long-term groundwater monitoring
program and institutional controls would be implemented under this alternative.

Alternative 3-In Situ
The in situ alternative includes the following remedial action components:
SVE. SVE would attempt to reduce the concentrations of TCE in the subsurface soils, where
accessible, in the area of the old maintenance shop off the northeast corner of the fire station. This
area is the suspected source of the TCE contamination found in the wells downgradient from this area.
The extraction and treatment system is discussed in Section 10.2.4. It was assumed the SVE
system would use five vertical extraction wells on an approximately 18.3-m (60-ft) spacing to remove
contaminated soil vapor from the assumed 37- by 37-m (120- by 120-ft) target area. The area is
currently planted in grass and would not be capped as part of the operation.
Based on assumed contaminant concentrations and expected contaminant removal rates, it is
estimated the SVE system would have to operate in this area for 1 to 3 years (6 months per year) to
meet the soil cleanup levels for TCE and related compounds in the vadose zone.
Bioventing. Bioventing would be used to treat any residual BTEX-contaminated soils beneath the
fire station parking lot. This area is the suspected source of the benzene and toluene found in the wells
downgradient from this area.
Conceptually, the bioventing system was assumed to include 20 vertical injection wells on
approximately 15-m (50-ft) centers to provide oxygen to the assumed 61-m by 76-m (200- by 250-ft)
contaminated zone to enhance in situ degradation. The air injection rate would be based on achieving
an optimal number of pore-volume exchanges per week to stimulate microbial degradation of the BTEX
compounds. No extraction wells would be used as part of the bioventing system, and no attempt would
be made to capture the injected air for treatment. The system would operate year-round.
It was previously estimated the bioventing system would have to operate year-round in this area for
2 to 4 years to meet the soil cleanup levels for BTEX compounds. Based on recent UWRL findings, it
appears that levels of BTEX are significantly lower than previously reported and that little residual
BTEX contamination exists in the vadose zone.
As described in Section 10.2.4, the groundwater would not be actively remediated. The TCE and
BTEX plumes in the shallow groundwater would continue to disperse and degrade naturally. Within
the groundwater, biodegradation, dispersion, dilution, and adsorption appear to be effectively
containing and degrading the contamination.
Any residual continuing source from the vadose zone soil would be treated by SVE in an estimated
1 to 4 years and by bioventing in 2 to 4 years. Because it is probable that groundwater concentrations
may remain above state and federal standards for an extended period of time, a long-term groundwater
monitoring program and institutional controls were included as part of this alternative.
Institutional controls and groundwater monitoring would be implemented ,as discussed in Sec-
tion 10.2.2, to restrict groundwater use, prevent human exposure to contaminants at concentrations
above state and federal standards, and maintain an accurate definition of the area of contamination.

Excavation of Soil. Under this alternative, approximately 2800 m3 (3700 cu yd) of VOC-
contaminated soil would be excavated from the TCE- and PCE-contaminated maintenance shop and
other source locations at source area WP45/SS57 and transported for disposal out-of-state as hazardous
waste. Excavation is expected to take one summer to complete. The excavation component is dis-
cussed in further detail in Section 10.2.5.
Bio venting. The BTEX-contaminated soils from beneath the fire station parking lot would be
treated with bioventing as described Alternative 3.
Under this alternative, the groundwater would not be actively remediated. Within the ground-
water, biodegradation, dispersion, dilution, and adsorption appear to be effectively containing and
degrading the contamination. The TCE and PCE in the vadose zone would be removed through exca-
vation and the BTEX in the vadose zone would be removed through bioventing. The chlorinated VOCs
and BTEX in groundwater would be allowed to attenuate through natural processes.
The continuing source from the vadose zone soil would be removed in 1 year and, by bioventing,
in 0 to 4 years. Because it is probable that groundwater concentrations will remain above state and
federal standards for an extended period of time, a long-term groundwater monitoring program and
institutional controls were included as part of this alternative.
Institutional controls and groundwater monitoring would be implemented, as discussed in Sec-
tion 10.2.2, to restrict groundwater use, prevent human exposure to contaminants at concentrations
above state and federal standards, and maintain an accurate definition of the area of contamination.
Alternative 5-In Situ/Extract
The in situ/extract alternative includes the following remedial action components:
SVE. SVE would be implemented, as discussed in Alternative 3, to treat TCE-contaminated soils
located near the old maintenance shop on the northeast corner of fire station (Building 1206).
Bioventing. Bioventing would be implemented, as discussed in Alternative 3, to treat BTEX-
contaminated soils beneath the fire station parking lot.
Groundwater Extraction and Treatment. This component would be implemented to remove and
treat VOC contaminated groundwater. The extraction network for this alternative is assumed to consist
of two extraction wells with a combined extraction rate of approximately 60 gpm. Extracted ground-
water will be treated as discussed in Section 10.2.3.
Based on modeling projections, the groundwater extraction and treatment system proposed under
this alternative would need to operate for at least 30 years. Year-round operation is assumed.
Institutional controls would be used to prevent exposure to groundwater until state and federal
standards are achieved.
The TCE and PCE in the vadose zone would be removed through SVE and the BTEX in the vadose
zone would be removed through bioventing. The chlorinated VOCs and BTEX in groundwater would
be reduced through extraction.
The continuing source from the vadose zone soil will be treated by SVE in an estimated 1 to

Alternative 6-Remove/Extract
The remove/extract alternative includes the following remedial action components:
Excavation of Soil. Excavation of VOC-contaminated soil would be implemented as discussed for
Alternative 4.
Bioventing. Bioventing would be implemented as discussed for Alternative 3.
Groundwater. The groundwater component is the same as described in Alternative 5.
The TCE and PCE in the vadose zone would be removed through excavation and the BTEX in the
vadose zone would be removed through bioventing. The chlorinated VOCs and BTEX in groundwater
would be reduced through extraction.
Based on a batch flush groundwater model, extraction of the TCE that is already in groundwater
could take 34 to 68 years for a plume In a highly permeable aquifer. The continuing source from the
vadose zone soil will be removed in 1 year and, by bioventing, in 0 to 4 years. Because it is probable
that groundwater concentrations will remain above state and federal standards for an extended period of
time, a long-term groundwater monitoring program and institutional controls was included as part of
this alternative.

10.5 Source Area SS61

the primary concern at source area SS61 is TCE in the groundwater. However, a breakdown
product of TCE, cis-l,2-DCE, was also found in the groundwater, and low-level TCE contamination
was found in the subsurface soil adjacent to the old dry well at the Vehicle Maintenance Building
(Building 3213). This dry well, along with surrounding soils, was removed during construction of the
new building.
The primary potential exposure pathway for source area SS61 is from the future unrestricted use of
contaminated groundwater. Therefore, contaminants in groundwater and the risk from continued
leaching of contaminants to groundwater are of primary concern. The groundwater contamination is

The descriptions identify the technologies, describe the representative process options, and present the
assumptions that provide the basis for the individual and comparative analyses.
Alternative 1-No Action
The no action alternative would be implemented as discussed in Section 10.2.1.
Alternative 2-Institutional Controls and Groundwater Monitoring
This alternative is a limited action alternative. It focuses on the following components.
Institutional controls and groundwater monitoring would be implemented, as discussed in Sec-
tion 10.2.2, to restrict groundwater use, prevent human exposure to contaminants at concentrations
above federal and state standards, and maintain an accurate definition of the area of contamination.
No evidence of residual dense non-aqueous phase liquid (DNAPL) is found at SS61. The
contamination is adsorbed and contained or is in a dissolved phase and not readily accessible for source
removal or treatment. The data indicate that natural processes are expected to achieve remediation
within the same relative timeframe as those predicted for active remediation.
This alternative would achieve the RAOs for source area SS61. It does not appear that a continuing
source of release is present in the vadose zone. However, if TCE-contaminated soils are present, they
would continue to act as a contaminant source to groundwater. Within the groundwater,
biodegradation, dispersion, dilution, and adsorption appear to be effectively containing and degrading
the contamination. Because of the potential for a continuing source and the probability that

groundwater concentrations will remain above state and federal standards for an extended period of

Alternative 3-Remove
The remove alternative includes the following remedial action components:
Excavation. If a significant source of residual contamination could be located, up to 115 m3
(150 cu yd) of contaminated soil would be excavated from the vadose zone on the north side of the
building at source area SS61 and placed in roll-off bins. Close observation of the building foundation
would occur during excavation. Pressure grouting may be necessary to facilitate the excavation. The
excavation and offsite treatment through incineration of the contaminated soil at source area SS61 is
expected to take one month to complete. Excavation is discussed in further detail in Section 10.2.5.
This component may not be applicable unless it is shown that a source of TCE is present in soil on the
north side of the building.
No action would be taken to treat groundwater. Within the groundwater, biodegradation,
dispersion, dilution, and adsorption appear to be effectively containing and degrading the
contamination. The natural dispersion of the TCE in groundwater may benefit from the remedial
activities designed to address the contaminant source if any was found.
If a TCE source is located in the vadose zone soils on the north side of the building, it would be
removed by excavation. The chlorinated VOCs in groundwater would be allowed to attenuate through
natural processes.
If located, any continuing source from the soil could be removed in 1 year. Because it is probable
that groundwater concentrations will remain above state and federal standards for an extended period of
time, a long-term groundwater monitoring program and institutional controls would be implemented
under this alternative.
Institutional controls and groundwater monitoring would be implemented, as discussed in Sec-
tion 10.2.2, to restrict groundwater use, prevent human exposure to contaminants at concentrations
above federal and state standards, and maintain an accurate definition of the area of contamination.
Alternative 4—Extract
In the extract alternative, only groundwater is treated; any residual contamination found in
subsurface soil is not treated. This alternative includes the following components:
Groundwater Extraction and Treatment. Would be used to capture the contaminant plume.
One extraction well would be installed at the downgradient edge of the plume, directly adjacent to the
building to extract groundwater from beneath the building. Extracted groundwater will be treated as
discussed in Section 10.2.3.
Based on modeling projections, the groundwater extraction and treatment system proposed under
this alternative would need to operate for at least 8 years. Year-round operation is assumed. Insti-
tutional controls would be used to prevent exposure until state and federal standards are achieved.

Institutional controls and groundwater monitoring would be implemented, as discussed in Sec-
tion 10.2.2, to restrict groundwater use, prevent human exposure to contaminants at concentrations
above federal and state standards, and maintain an accurate definition of the area of contamination.

11.0 Description of Alternatives - OU 4
This section provides a concise description of the remedial action objectives and remedial alter-
natives for each source area in OU 4. The feasibility study provides information on the assumptions
and calculations used in the development of the alternatives and the cost estimates for the alternatives.
11.1 Remedial Action Objectives
Remedial action objectives (RAOs) were developed to specify actions and contaminant levels neces-
sary to protect human health and the environment. RAOs define the contaminants of concern, expo-
sure routes and receptors, and remediation levels, which are defined as acceptable contaminant levels
for each exposure route.
The specific RAOs for the source areas within OU 4 are as follows:
• At DP25, prevent the continued migration of contaminants (BTEX) into the groundwater from the
floating product and smear zone.
• At ST58, prevent the continued migration of benzene into the groundwater at a concentration that
presents an unacceptable risk to future groundwater users.
• At DP25 and ST58. prevent human exposure to groundwater contaminated above state and federal
standards.
• At SS35, clarify the extent of DDT contamination in surface soil, prevent migration of DDT from
the surface soils into Garrison Slough, and remove any drums, if practical, that may present a
threat of future release of hazardous materials to the environment.
The goal of the Superfund approach is to return usable groundwaters to their beneficial uses within
a timeframe that is reasonable, given the particular circumstances of the site. Reasonable restoration
time periods may range from very rapid (one to five years) to relatively extended (several decades).
Factors, such as location, proximity to population, anticipated future land use, and mobility of the
contaminant plume are considered when determining an appropriate restoration timeframe.
The use of: (1) natural attenuation with institutional controls, (2) source reduction through treating
soil contamination to prevent additional contaminant leaching into the groundwater, and (3) ground-
water pumping and treating were considered viable options for addressing groundwater contamination
at Eielson AFB. For source areas within OUs 3. 4, and 5, the following site specific conditions were
considered when determining reasonable restoration timeframes:
• Contaminant plumes in this relatively homogeneous aquifer do not appear to be spreading or
are decreasing in size.
• Biodegradation, dispersion, dilution, or adsorption appear to be effectively containing or
reducing the size of the contaminant plume.
FINAL 11.1 ' September 1995

Eielson AFB OUs 3, 4, and 5 Record of Decision
Areas impacted by the contamination are relatively small with little likelihood anticipated of
extended exposure to groundwater.
Future land use as a military installation is not anticipated to change in the foreseeable future.
11.2 Remedial Action Components
Two source areas within OU 4 (DP25 and ST58) contain groundwater and soils contaminated with
petroleum hydrocarbons, BTEX; lead and DDT have been found in surface soils only at SS35. The
individual alternatives to address these three source areas are assembled from one or more of the
following remedial action components:
• No Action
Components to Address Groundwater Contamination
• Institutional Controls and Groundwater Monitoring
• Groundwater Extraction and Treatment
Components to Address Soil Contamination
• Excavation/Removal
• Cover for Containment in Place
• Bioventing
The no action alternative does not address the RAOs established for each source area. It represents
the baseline risk without institutional controls or active remediation. The institutional controls and
groundwater monitoring alternative prevents the use of contaminated groundwater, but does not include
active remediation. The other components provide a range of control with varying timeframes to
achieve the RAOs. Because it is difficult to remove all of the residual contamination and to reduce
groundwater contaminant concentrations below state and federal water quality standards, even with
groundwater extraction and treatment, it is expected that all of the alternatives would require long-term
management of the area.
The six remedial action components are described in the following paragraphs. Following this
discussion, the components are assembled into remedial action alternatives for each of the source areas.
Costs for the alternative for each source area is included in Table 11.1.
11.2.1 No Action
Under this approach, no action is taken to remove contaminants from the soils or the groundwater.
It represents the baseline risk without institutional controls or active remediation. Evaluation of the no
action approach is required by the NCP to provide a baseline against which other alternatives can be
compared. Under the no action alternative, no remedial measures are implemented, including long-
term review, monitoring, or controls. No direct costs are associated with the no action alternative.

11.2.2 Institutional Controls and Groundwater Monitoring
Institutional controls are used to prevent current and future human exposure to contamination
remaining at the source areas at concentrations above health-based risk levels and federal and state
standards. Specific controls include restrictions limiting access to the source areas and administrative
controls to limit groundwater and future land use. Access restrictions, including such measures as
permanent markers are used to prevent direct human exposure to contaminants. Groundwater restric-
tions are implemented by placing written notification in base policies prohibiting the use of contam-
inated groundwater. In addition, all existing and any new wells located in or near the contaminated
portion of the aquifer shall be locked to prevent unauthorized use.
The administrative controls for limiting future land use include placing written notification of these
remedial actions in the base land use master plan. The notification shall prohibit any activity that

disrupts aspects of the engineered controls. A copy of the notification is provided to any prospective
transferees of the property and is included in any transfer documents, including deeds, in the event that
the Air Force released control of the affected property. The Air Force shall provide EPA and the State
with written verification that notification! s) have been implemented.
11.2.3 Groundwater Extraction and Treatment
Groundwater extraction was evaluated for source areas DP25 and SS58 as a way to potentially
accelerate aquifer restoration. Groundwater extraction focuses on reduction of contaminant mass
through removing the dissolved constituents in groundwater. It involves removing contaminated
groundwater for aboveground physical/chemical treatment. The estimated number and location of
extraction wells, as well as estimated timeframes to achieve cleanup, are discussed in Sections 11.3 and
11.5.
Due to the high metals levels naturally found in the groundwater at Eielson AFB, metals removal
may be necessary prior to treating the water for site-specific contamination. Treatability studies are
recommended to evaluate iron fouling problems and determine if the sludge generated by dissolved
metals would be a hazardous waste. In addition, no proven method is known for removing lead from
groundwater at a reasonable cost in a reasonable amount of time. However, a treatability test is being
performed at another site at Eielson AFB to determine the fate and transport of lead and the most viable
option for extraction and treatment, if warranted. Results from this test will be used to further evaluate
lead remediation at ST58.
The need for air emission controls would be evaluated and implemented in accordance with the
Clean Air Act (42 USC 7401). Treated groundwater would be discharged to surface water in accord-
ance with federal ambient water quality criteria, and state 18 AAC 70, and 18 AAC 72.
11.2.4 Excavation/Removal
The excavation/removal component is a source control measure involving the excavation and
removal of contaminated materials for offsite or onsite treatment or disposal. For source area DP25,
contaminated soils would be excavated. For source area SS35, drums would be removed and contam-
inated soil would be excavated. Three disposal options, onsite, offsite, or oftsite with treatment, were
evaluated for disposal of contaminated material from SS35. The excavated area would then be back-
filled with clean material.
11.2.5 Cover
The cover component was evaluated for SS35 and involves placement of a soil cover over the
surface of the source area eliminating direct contact with surface contamination and runoff into nearby
Garrison Slough. The type of cover material is dependent on the specific remedial action objectives for
the source area.
11.2.6 Bioventing
Bioventing was evaluated for source area SS58. The bioventing component involves enhancing the
destruction of fuel-derived organic constituents in soil by injecting air into the soil to sustain naturally
occurring microorganisms that break down the fuel. The number of injection wells and estimates of
treatment times are provided in Section 11.5.

11.3 Source Area DP25
11.3.1 Site Conditions
The primary concerns at source area DP25 are the presence of a layer of fuel-saturated soils at the
water table, BTEX-contaminated soils in the smear zone, and BTEX compounds and lead in the
groundwater. The primary potential exposure pathway for source area DP25 is from the future
unrestricted use of contaminated groundwater. Therefore, contaminants in groundwater and the risk
from continued leaching of contaminants to groundwater are of primary concern.
A source control program to identify and replace leaking tanks or pipes and line the berms will be
implemented as part of the base tank program. This plan would include locating and repairing leaking
tanks and piping, removing 0.3 to 0.6 m (1 to 2 ft) of gravel within the berms, installing an imper-
meable liner, and replacing the gravel. The alternatives developed for source area DP25 assume that
no fuel continues to leak into the soil.
11.3.2 Remedial Alternatives
In accordance with NCR guidance, a range of potential remedial alternatives have been developed.
The alternatives range from no action to removal for ex situ treatment and disposal. Four compre-
hensive alternatives have been developed to address the contaminated soil, floating fuel, and
contaminated groundwater at source area DP25. The alternatives are summarized in Table 11.2.

Alternative 1 - No Action
The no action alternative was evaluated as discussed in Section 11.2.1.
Alternative 2 - Institutional Controls and Groundwater Monitoring
This alternative is a limited action alternative consisting of the following components.
Under this alternative, floating fuel and BTEX-contaminated soils beneath the storage tanks would
continue to act as a contaminant source to groundwater and the groundwater would not be actively
remediated. Remediation time in this case is a function of natural processes in groundwater including
sorption/desorption, biodegradation. and contaminant dispersion resulting from groundwater flow
through the aquifer.
Based on currently observed concentrations in the soil and groundwater, it was estimated that
BTEX constituents may continue to leach into groundwater. Within the groundwater, biodegradation,
dispersion, dilution, and adsorption appear to be effectively degrading the contamination and containing
it within the bermed areas around the tanks. Because of this continuing source of release and the
probability that groundwater concentrations will remain above federal and state standards for an
extended period of time, a long-term groundwater monitoring program and institutional controls are
included as part of this alternative.
Institutional controls and groundwater monitoring would be implemented, as discussed in Sec-
tion 11.2.2, to restrict groundwater use, prevent human exposure to contaminants at concentrations
above state and federal standards, and maintain an accurate definition of the area of contamination.
Alternative 3—Limited Removal
The limited removal alternative focuses on reducing the long-term source of contamination in soils
at source area DP25 to the extent possible without interfering with the integrity of the tank berms. The
removal alternative includes the following components.
It is assumed that approximately 21,000 m3 (28,000 cu yd) of BTEX-contaminated soil would be
excavated for treatment onsite using composting or landfarming. The excavated soil would include the
top 30.5 cm (12 in.) of soil from the entire area within the berm, approximately 153 m3 (200 cu yd) of
BTEX-contaminated soil from the area of the fuel spill near monitoring well 53M01, and soils to the
top of the water table at approximately 1.2 m (4 ft) bis from the areas where floating fuel has been
identified. The excavation of soil from these areas could be completed in one construction season.
Because some of the source would be removed, RAOs may be achieved slightly faster under this
alternative than without source control. The groundwater would not be actively remediated. The
contaminants would be allowed to disperse and degrade naturally. Within the groundwater, biodegra-
dation, dispersion, dilution, and adsorption appear to be effectively containing and degrading the
contamination. Because some soil and smear zone contamination will remain above state and federal
standards for an extended period of time, a long-term groundwater monitoring program and institu-
tional controls are included as part of this alternative.

tion 11.2.2 to restrict groundwater use. prevent human exposure to contaminants at concentrations
above state and federal standards, and maintain an accurate definition of the area of contamination.
Alternative 4-Extract
The extract alternative focuses on reducing the contaminant mass in groundwater. It includes
short-term active skimming of floating product in conjunction with high-rate extraction of groundwater
with treatment. The three components of the extract alternative are briefly outlined as follows.
Active skimming and pumping of approximately seven dual-phase extraction wells would be used
to address the floating fuel layer at source area DP25. The active skimming wells, equipped with
groundwater extraction pumps and product skimmer pumps, would be installed within the bermed area
as part of this alternative. During the active skimming phase of operation, the groundwater extraction
rate would be optimized to enhance product recovery, while minimizing the chance of distributing the
product over a larger area. The alternative assumes the system will operate year-round for 3 years and
recover a small fraction of the product present (150.000 L [40.000 gal]). The recovered fuel would be
sent to the power plant to be burned.
When no more fuel can be recovered through active skimming and to minimize the potential for
any further distribution of residual undissolved contamination, full-scale groundwater extraction would
be implemented. It is assumed that two extraction wells would be installed downgradient of the two
areas with residual floating fuel and would be pumped at a rate to remove as much contaminated
groundwater as possible. The combined extraction rate of both wells is estimated to be 80 gpm.
The extracted groundwater would be treated using an air stripper to remove the VOCs and using
activated carbon to remove SVOCs from the extracted water as described in Section 11.2.3. The
effluent from the treatment system would be discharged to Hardfill Lake. The need for air emission
controls would be evaluated and implemented in accordance with the Clean Air Act (42 USC 7401).
Treated groundwater would be discharged to surface water in accordance with federal ambient water
quality criteria, and state 18 A AC 70. and 18 AAC 72.
Based on modeling projections, the high-rate groundwater extraction and treatment system
proposed under this alternative would need to operate for more than 30 years after the active skimming
operation has ceased. Year-round operation is assumed, although permafrost present in the area will
affect yearly maintenance requirements.
The BTEX in the residual fuel and soils will continue to act as a source of contaminants to ground-
water for an estimated 60 years. Removal of some of the contaminant mass through groundwater
extraction may achieve the RAOs slightly faster. In addition, contaminants not treated would be
allowed to disperse and degrade naturally. Within the groundwater, biodegradation, dispersion,
dilution, and adsorption appear to be effectively containing and degrading the contamination. Because
the continuing source of contamination will remain above state and federal standards for an extended
period of time, a long-term groundwater monitoring program and institutional controls are included as
pan of this alternative.
Institutional controls and groundwater monitoring would be implemented as discussed in Sec-
tion 11.2.2 to restrict groundwater use, prevent human exposure to contaminants at concentrations
above state and federal standards, and maintain an accurate definition of the area of contamination.

11.4 Source Area SS35
11.4.1 Site Conditions
The primary concern for source area SS35. is from DDT found in the surface soils in an area
adjacent to Garrison Slough. DDT has also been found in the sediment samples from Garrison Slough
in the vicinity of source area SS35. In addition, drums that may contain hazardous materials may be
buried in three small disposal areas within the site. Groundwater in this area does not pose an
unacceptable risk to human health and the environment.
Based on the homogeneous nature of the site and the limited data available, the extent of the con-
tamination and, therefore, the volume of contaminated soil, cannot be well defined. It is not known
whether these concentrations represent hot spots associated with drum burial areas where the samples
were taken or whether DDT contamination could be more widespread. Based on the 1994 data, 6.5 kg
(13.3 Ib) of DDT was estimated to be spread over 459 m3 (600 cu yd) of DDT-contaminated soil.
SS35 appears to be acting as a source of surface water or sediment contamination. PCBs and
pesticides, particularly DDT, were found in soil at source area SS35, which is located adjacent to
Garrison Slough. Elevated body burdens of DDT were found in fish caught near SS35. Cumulative
ecological risks at Eielson AFB are currently being evaluated under the Sitewide program. Preliminary
conclusions indicate that SS35 may present reproductive risks to birds and mammals from ingestion
exposure to PCBs and DDT. The Sitewide biological risk assessment addresses ecological risks from
all areas on base.
11.4.2 Remedial Alternatives
Based on the remedial objectives, four remedial alternatives were developed for source area SS35.
The alternatives are listed in Table 11.3. The following subsections describe the remedial alternatives
developed for source area SS35. The descriptions provide details about the technologies, describe

Alternative 2 - Control
The control alternative is a limited action alternative that includes institutional controls and ground-
water monitoring. It focuses on the use of institutional controls to prevent human intrusion into the
drum disposal areas. The alternative includes base policies restricting access to the area as described in
Section 11.2.2.
The control alternative would not achieve RAOs for source area SS35. The DDT in surface soil
would continue to be a potential exposure hazard to human and ecological receptors until it degraded.
Institutional controls would also not prevent surface water runoff into Garrison Slough.
Alternative 3 - Cover
The cover alternative consists of the installation of a cover as described in Section 11.2.5. The soil
cover serves to prevent the migration of contaminants into Garrison Slough by overland runoff and to
prevent direct soil contact and ingestion of contaminated surface soils by the base personnel and
ecological receptors. The cover is proposed for those areas where DDT has been detected above risk-
based levels in the surface soil. In this alternative, the contamination would be contained until natural
processes eventually degraded the DDT.
The soil cover would be designed to coordinate with the existing contours to facilitate runoff and
minimize the need for maintenance. The cover would extend beyond the areas where risk-based levels
are exceeded and would be tapered, as appropriate, to the existing grade. It is assumed the cover
consists of 15.2 cm (6 in.) of native top soil overlying 30.5 cm (12 in.) of native sand and gravel.
Both layers would be placed in horizontal lifts and compacted. After the cover is placed, the surface
would be planted with grass to stabilize the soil cover. Construction of the soil cover could be
completed within one summer season.
Alternative 4—Removal
The removal alternative consists solely of the excavate/remove component discussed in Sec-
tion 11.2.4. It focuses on removing and disposing of surface soil with DDT concentrations above risk-
based levels. Removal of this soil would prevent migration of contaminants into Garrison Slough and
prevent exposure through direct contact and ingestion. In addition, buried drums, if found, would be
excavated and residual contents would be consolidated, characterized, and incinerated, if necessary.
A description of the primary components follows.
Soil in areas where DDT exceeds risk-based levels would be excavated from the site. It is esti-
mated the extent of contaminated surface soil is less than 0.3 m (1 ft) deep and covers an area of
approximately 279 m2 (3000 ft2) which would produce approximately 459 m3 (600 cu yd) of contami-
nated soil. The soil would be disposed in one of three ways: (1) by offsite transportation and incinera-
tion. (2) by offsite transportation and landfill disposal in a county landfill, or (3) by disposal in an on-
base landfill. Although the soil is not expected to be a RCRA waste, the concentrations are higher than
the universal treatment standard, as published in the land disposal restrictions. Therefore, the county
landfill may not accept this material. An alternate disposal option for this small amount of material
would be to place it in an on-base landfill. This action would remove the contaminated soil from the
vicinity of Garrison Slough and place it in a managed landfill.
Three areas of the site that exhibited magnetic anomalies are presumed to contain up to 200 buried
drums. Part of this alternative consists of excavating soil to remove, consolidate, characterize, and
FINAL 11.9 September 1995

dispose of the drums. It is estimated that up to 8410 m3 (11,000 cu yd) of soil would have to be
excavated to remove all of the drums. One fourth of the drums are assumed to contain residual
material that must be incinerated. The soil surrounding the drums is assumed to be uncontaminated
and suitable for backfilling the excavation. After excavation, the drums will be opened, characterized,
and consolidated for offsite transportation and incineration.
11.5 Source Area ST58
11.5.1 Site Conditions
The primary concern for source area ST58 is benzene and lead in the groundwater. Petroleum
hydrocarbons were also found in the subsurface soils.
The primary potential exposure pathway for source area ST58 is from the future unrestricted use of
contaminated groundwater. Therefore, contaminants in groundwater and the risk from continued
leaching of contaminants to groundwater are of primary concern.
11.5.2 Remedial Alternatives
Four alternatives were developed for remediation of ST58 and are listed in Table 11.4. Descrip-
tions for each of the four alternatives is presented in the following.

ination. Because of this continuing source of release and the probability that groundwater

concentrations will remain above federal and state standards for an extended period of time, a long-
term groundwater monitoring program and institutional controls are included as part of this alternative.
• Institutional controls and groundwater monitoring would be implemented, as discussed in Sec-
tion 11.2.2. to restrict groundwater use. prevent human exposure to contaminants at concentrations
above state and federal standards, and maintain an accurate definition of the area of contamination.
Alternative 3—In Situ
The in situ alternative consists of the following remedial action components: •
Bioventing is implemented.as described in Section 11.2.6. to reduce the BTEX concentrations in
soils. BTEX in the groundwater would be allowed to attenuate through natural processes. It has been
assumed that hot spots have been removed and bioventing will achieve long-term bioremediation of
residual contaminants in the soil. Bioventing employs a target air flow rate through the vadose zone to
optimize oxygen availability for microbial growth.
It is assumed the bioventing system would use nine vertical injection wells on a 15.2-m (50-ft)
spacing. The injection wells would be used to introduce oxygen or withdraw soil vapor from an
assumed 45.7- to 91.4-m (150- by 300-ft) target area. The air injection rate would be.based on
achieving an optimal number of pore-volume exchanges per week for contaminant degradation. BTEX
in vadose zone soils is expected to be removed by bioventing after a period of 1 year.
Based on currently observed concentrations in the soil and groundwater, it was estimated that
BTEX constituents may continue to leach into groundwater. Because it is probable the groundwater
concentrations may remain above state and federal standards for an extended period of time, institu-
tional controls and groundwater monitoring will be implemented, as described in Alternative 2.
Alternative 4-In Situ/Extract
The in situ/extract alternative consists of the following remedial action components:
Bioventing will be implemented as described in Alternative 3 to remove vadose zone BTEX
constituents.
Groundwater extraction and treatment will be implemented, as described in Section 11.2.3, to
expedite groundwater restoration. A single extraction well removing approximately 40 gpm is assumed
for this alternative. The extracted groundwater would be treated using an air stripper to remove the
VOCs and using activated carbon to remove other petroleum contaminants from the water. The treated
effluent would be discharged to Garrison Slough. The need for air emission controls would be
evaluated and implemented in accordance with the Clean Air Act (42 USC 7401). Treated ground-
water would be discharged to surface water in accordance with federal ambient water quality criteria,
18 AAC70, and 18 AAC72.
Because it is probable the groundwater concentrations may remain above state and federal
standards for an extended period of time, institutional controls and groundwater monitoring will be
implemented as described in Alternative 2.

12.0 Description of Alternatives-OU 5
This section provides a concise description of the remedial action objectives and remedial alter-
natives for source areas LF03/FT09 in OU 5. Detailed information on the assumptions and calcu-
lations used in the development of the alternatives are presented in the FS.
12.1 Remedial Action Objectives
The primary contaminants of concern at source areas LF03/FT09 are TCE, PCE, vinyl chloride,
and 1.4-dichlorobenzene in the groundwater directly beneath the landfill. The specific objectives are,
therefore, to
• prevent direct human contact with landfill contents
• minimize the migration of chlorinated VOCs into the groundwater
• control surface water runoff and erosion
• continue to comply with state and federal standards at the boundary of the waste management area.
12.2 Site Conditions at Source Areas LF03/FT09
The main part of the landfill was excavated to a depth below the groundwater table. During the
time the landfill was active, wastes were reportedly dumped into the standing water. The shallow
trenches on the eastern side of the landfill may be above the water table. This theory will be confirmed
in the remedial design phase. The trenches were active during the early 1980s and received waste from
the base, including industrial wastes and solvents from the flightline shops. The fire training area
(source area FT09) was located on top of the fill in the west-central portion of the landfill. During fire
training exercises, JP-4 and other liquids were dumped into an unlined pit and ignited. The soils and
waste in the fire training area are contaminated with fuel and solvents.
12.3 Remedial Alternatives
Four alternatives have been developed to address the landfill and fire training area at LF03/FT09.
The alternatives are presented in Table 12.1 and are described in the following subsections. Costs are
presented in Table 12.2.
12.3.1 Alternative 1 -No Action
Under this alternative, no action would be taken to remove contaminants from or prevent exposure
to the landfill or groundwater in source area LF03/FT09. It represents the baseline risk without
institutional controls or active remediation. Evaluation of the no action alternative is required by the
NCP to provide a baseline against which other alternatives can be compared. The no action alternative
will not protect human health or the environment or achieve RAOs. No risk reduction or reduction in
the toxicity, mobility, or volume of contaminants will occur. No direct cost is associated with the no
action alternative.

12.3.2 Alternative 2-Institutional Controls and Groundwater Monitoring
Institutional controls are implemented to achieve one or more of the following:
• prevent human contact with the landfill waste.
• prevent exposure to groundwater contaminants at concentrations above state and federal standards.
• restrict access or development on the landfill.
Institutional controls are implemented to reduce potential risks from intrusion into the landfill or
the use of contaminated groundwater from beneath the landfill.
This alternative is a limited action alternative. It consists of the following components:
Groundwater monitoring is conducted at the edge of the waste management area to monitor any
migration of contaminants from the source areas LF03/FT09 landfill beyond the boundary of the waste
management area and Garrison Slough. Monitoring will also be performed at the edge of the waste
management area to confirm continuing compliance with state and federal standards.

This alternative would not achieve the remedial action objectives for source areas LF03/FT09.
Without proper closure, the landfill debris, which may include buried drums of organic contaminants
and the residual soil contamination at the fire training area, is likely to pose a risk from direct contact
and uncontrolled surface runoff.
12.3.3 Alternative 3 - Cover
The cover alternative includes the following components:
A soil cover would be placed over the landfill area in accordance with applicable or relevant and
appropriate requirements of RCRA Part 264. The cover would minimize the long-term migration of
liquids from the landfill and would prevent direct contact with landfill debris and contaminated soil.
Conceptually, the covered area would be less than 40.5 hectares (100 acres) in size. The cover
would consist of native soil (sand and gravel) excavated from the base and placed and graded to
provide a minimum 1 percent slope. Fine soil, if available, would be more suitable material for the
cap, because the permeability of the cap would be reduced. Because the cover would promote surface
water drainage, a drainage system (perimeter ditches) would be included to direct and manage surface
runoff.
The cover alternative would reduce or eliminate the threat of direct contact of personnel with
buried landfill debris. It would also help control surface water runoff and erosion and, subsequently,
will reduce the leaching of contaminants to groundwater.
Currently, no state or federal standards are exceeded at the edge of the waste management area, but
institutional controls and groundwater monitoring will be implemented to achieve the following:
• prevent human contact with the landfill waste.
• prevent exposure to groundwater contaminants at concentrations above state and federal standards.
• restrict access or development on the landfill.
Institutional controls are implemented to reduce potential risks from intrusion into the landfill or
from use of contaminated groundwater from beneath the landfill. Groundwater monitoring is
conducted at the edge of the waste management area to monitor any migration of contaminants from the
source areas LF03/FT09 landfill beyond the boundary of the waste management area and Garrison
Slough. Monitoring will also be performed to confirm continuing compliance with state and federal
standards at the edge of the waste management area.
12.3.4 Alternative 4-Cap
The existing open area of source areas LF03/FT09 would be capped or covered as part of this
alternative. The cap alternative includes the following components:
A soil cover, as described in Alternative 3, would be placed over the LF03/FT09 landfill area,
where appropriate.
For areas requiring a composite cover under RCRA Part 264. some areas of LF03 may be capped
with a multi-layer geosynthetic cap. Conceptually, the capped area was assumed to be about
8.1 hectares (20 acres) in size. The cap would reduce the release of landfill contaminants to the
groundwater through leaching for material existing above the groundwater table. Landfill gas vents to

release methane would be installed, as needed, to adequately vent the landfill. A drainage system
would be included to direct and manage surface runoff. The capped area would be fenced to minimize
traffic over it that could damage the cap components.
The cap alternative would achieve RAOs relating to the elimination of exposure to the waste
materials, controlling surface water runoff and erosion, and reducing infiltration to subsequently reduce
leaching of contaminants to groundwater.
Currently, no state or federal standards are exceeded at the edge of the waste management area, but
institutional controls and groundwater monitoring will be implemented to reduce potential risks from
intrusion into the landfill or from use of contaminated groundwater from beneath the landfill. Ground-
water monitoring is conducted at the edge of the waste management area to monitor any migration of
contaminants from the source areas LF03/FT09 landfill beyond the boundary of the waste management
area and Garrison Slough. Monitoring will also be performed to confirm continuing compliance with

13.0 Summary of the Comparative Analysis of Alternatives
In accordance with federal regulations, the cleanup alternatives for each source area were evaluated
based on the nine criteria presented in the National Contingency Plan (NCP). The nine criteria are
divided into three groups as follows:
Threshold Criteria - Must be met by all alternatives:
(1) Overall Protection of Human Health and the Environment. How well does the alternative protect
human health and the environment, both during and after construction?
(2) Compliance with Applicable or Relevant and Appropriate Requirements. Does the alternative meet
all applicable or relevant and appropriate state and federal laws?
Balancing Criteria - Used to compare alternatives to each other:
(3) Long-Term Effectiveness and Permanence. How well does the alternative protect human health
and the environment after cleanup? What, if any, risks will remain at the area?
(4) Reduction of Toxicity. Mobility, or Volume Through Treatment. Does the alternative effectively
treat the contamination to significantly reduce the toxicity, mobility, and volume of the hazardous
substance?
(5) Short-term Effectiveness. Are there potential adverse effects to either human health or the
environment during construction or implementation of the alternative? How fast does the
alternative reach the cleanup goals?
(6) Implementabilitv. Is the alternative both technically and administratively feasible? Has the
technology been used successfully at similar areas?
(7) Cost. What are the relative costs of the alternatives?
Modifying Criteria - Evaluated as a result of public comments:
(8) State Acceptance. What are the state's comments or concerns about the alternatives considered and
about the preferred alternative? Does the state support or oppose the preferred alternative?
(9) Community Acceptance. What are the community's comments or concerns about the alternatives
considered and about the preferred alternative? Does the community generally support or oppose
the preferred alternative?
This section contains the results of the comparative analyses for the source areas DP44,
WP45/SS57, SS61, DP25, SS35, ST58, and LF03/FT09 where alternatives were evaluated in the
Feasibility Study.

13.1.1 Threshold Criteria
Overall Protection of Human Health and the Environment:
All of the alternatives, except the No Action alternative, would implement institutional controls to
prevent exposure to contaminated groundwater until federal and state regulatory levels are achieved.
The SVE/extract alternative would be designed to treat contaminated soils and groundwater and could
theoretically achieve cleanup objectives more quickly than either Alternative 3, which includes source
reduction to treat the soil contamination in the unsaturated zone or Alternatives 1 and 2, which rely on
natural processes.
Although the alternatives include varying levels of contaminant removal, all alternatives are
expected to require an extended period of time to comply with all state and federal regulatory levels
throughout the contaminant plume. For this source area, source reduction using SVE may be
warranted, if sufficient contamination remains in the vadose zone.
Compliance with Applicable or Relevant and Appropriate Requirements (ARARs):
The primary ARARs for this source area focus on groundwater protection. Compliance with
ARARs include compliance with federal MCLs and with State of Alaska Water Quality Standards
(18 A AC 70). All alternatives will eventually comply with groundwater chemical-specific ARARs and,
with the exception of the No Action alternative, would prevent exposure to contaminated groundwater
through the use of institutional controls. The period for compliance with all state and federal regu-
latory levels may be decreased through implementation of Alternative 3, SVE, or Alternative 4,
SVE/Extract.
It is expected that all action-specific ARARs could be met by all alternatives, including air emission
limitations and surface water discharge levels. No action-specific ARARs exist for Alternative 1, No
Action, or Alternative 2, Institutional Controls/Groundwater Monitoring.

Overall Protection of Human Health and the Environment:
All of the alternatives, except the No Action alternative, would implement institutional controls to
prevent exposure to contaminated groundwater until federal and state regulatory levels are achieved.
Alternative 6 would be designed to treat both contaminated soils and groundwater and could
theoretically achieve cleanup objectives more quickly than either Alternatives 3, 4, or 5 which include
SVE, bioventing, and/or soil excavation.to reduce the source of groundwater contamination in the
unsaturated soils. Alternatives 1 and 2 rely on natural processes to achieve groundwater cleanup
levels. Recent data indicates that little residual contamination remains in the vadose zone. Within the
groundwater, biodegradation, dispersion, dilution, and adsorption appear to be effectively containing
and degrading the contamination.
Although the alternatives include varying levels of contaminant removal, all alternatives are expected to
require an extended period of time to comply with all state and federal regulatory levels throughout the
contaminant plume.
Compliance with Applicable or Relevant and Appropriate Requirements (ARARs):
The primary ARARs for this source area focus on groundwater protection. Compliance with ARARs
include compliance with both federal MCLs and with state of Alaska Water Quality Standards (18 AAC

exception of the No Action alternative, all would prevent exposure to contaminated groundwater
through the use of institutional controls. The period for compliance with all state and federal
regulatory levels is not expected to be significantly decreased through source removal or groundwater
extraction/treatment.
It is expected that all action-specific ARARs could be met by all alternatives, including air emission

Alternatives 3 and 4 would be designed to treat either contaminated soils or groundwater and could
theoretically achieve cleanup objectives more quickly than either Alternatives 1 or 2 that rely on natural
processes to achieve groundwater cleanup levels. Dry wells and surrounding soils were removed
during construction of the new building and little residual contamination is expected in the unsaturated
soils. Unless additional soil contamination is identified, soil excavation is not expected to decrease the
time to reach RAOs. Within the groundwater, biodegradation, dispersion, dilution, and adsorption
appear to be effectively containing and degrading the contamination within an area below the building.

Overall Protection of Human Health and the Environment:
All of the alternatives, except the No Action alternative, would implement institutional controls to
prevent exposure to contaminated groundwater until federal and state regulatory levels are achieved.
Alternatives 3 and 4 would be designed to treat either contaminated soils or groundwater, if accessible,
and could theoretically achieve cleanup objectives more quickly than either Alternatives 1 or 2 that rely
on natural processes to achieve groundwater cleanup levels. Groundwater and soil contamination
appear to be confined beneath the bermed area containing the tank farm. Within the groundwater,
biodegradation, dispersion, dilution, and adsorption appear to be effectively containing and degrading
the contamination within an area below this tank farm.
The success of the contaminant removal under the various alternatives is dependent upon the
accessibility of the contamination and the implementability of a treatment system beneath the tank farm.
Given the potential inability to treat a significant amount of contamination in either the subsurface soils
or the groundwater, all alternatives are expected to require an extended period of time to comply with
all state and federal regulatory levels throughout the contaminant plume.
Compliance with Applicable or Relevant and Appropriate Requirements (ARARs):
The primary ARARs for this source area focus on groundwater protection. Compliance with

Long-term effectiveness and permanence
Alternatives 1 and 2 both rely on natural processes to degrade contamination, but
Alternative 2 prevents use of contaminated groundwater. Alternatives 3 and 4 treat
the source in soil to minimize future contaminant migration. In addition.
Alternative 4 includes groundwater treatment and therefore addresses more of the
contamination. However, its effectiveness in achieving groundwater standards is
not well-established.
Reduction of toxicity, mobility, or volume through treatment
Neither Alternative 1 or 2 includes treatment. Alternatives 3 and 4 reduce toxicity
and volume through treatment, but Alternative 4, which includes groundwater
treatment, would treat a larger portion of the contamination.
Short-term effectiveness
Although the effectiveness of groundwater extraction and treatment is not
well-established, Alternative 4 might achieve cleanup standards more quickly than
Alternative 3.
Implementability
Under Alternatives 2-4, institutional controls are readily implementable.
Alternatives 3 and 4 include readily available technologies. Alternative 4 is more
difficult to implement due to the additional need for installation and construction
of a groundwater extraction and treatment system and operational difficulties in an
arctic climate.

14.0 Selected Remedies
This section presents the source areas that require no further action, followed by a discussion of the
selected remedies for the source areas in OUs 3, 4 and 5 that require action. Table 14.1 summarizes
the selected remedy for each source area. Table 14.2 provides a summary of the estimated costs of the
selected remedies.
The goal of the Superfund approach is to return usable ground waters to their beneficial uses within
a timeframe that is reasonable, given the particular circumstances of the site. Reasonable restoration
time periods may range from very rapid (1 to 5 years) to relatively extended (several decades). Fac-
tors, such as location, proximity to population, anticipated future land use, and mobility of the
contaminant plume, are all considered when determining an appropriate restoration timeframe. The
use of: (1) natural attenuation with institutional controls, (2) source reduction through treating soil
contamination to prevent additional contaminant leaching into the groundwater; and (3) groundwater
pumping and treating were all considered viable options for addressing groundwater contamination at
Eielson AFB. For source areas within OUs 3,4, and 5, the following site-specific conditions were
considered when determining reasonable restoration timeframes:
• Contaminant plumes in this relatively homogeneous aquifer do not appear to be spreading or are
decreasing in size.
• Biodegradation, dispersion, dilution, or adsorption appear to be effectively containing or reducing
the size of the contaminant plume.
• Areas impacted by the contamination are relatively small with little likelihood of extended exposure
to groundwater anticipated.
• The future land use as a military installation is not anticipated to change in the foreseeable future.
For source areas at Eielson AFB. natural attenuation, in combination with institutional controls or
source reduction, was selected in situations where reduction of contamination in the groundwater would
be attained in a similar timeframe as active remediation of the groundwater.
14.1 No Further Action Sites
As indicated in Section 4.1, the source evaluation screening process found that three areas (LF01,
WP32, and DP55) contained contaminants below screening levels or the affected pathway was incom-
plete; therefore, no further action under CERCLA is required. For the source areas within OUs 3, 4,
and 5, the cumulative risk for source areas LF02, LF04, LF06, ST27, WP33, SS36, SS37, SS39/SS63,
and SS64 is within acceptable regulatory levels and, therefore, environmental cleanup is not proposed
for these 10 source areas under CERCLA. The Air Force will continue to monitor groundwater on the
base to ensure compliance with state and federal regulations, and to ensure that groundwater use does
not pose an unacceptable risk to human health or the environment.
FINAL 14.1 September 1995
-------
Eielson AFB OUs 3, 4, and 5 Record of Decision
Under a separate federal program, the Air Force has submitted a closure plan for the ordnance area
at LF04 under the Resource Conservation and Recovery Act (RCRA), Section 3008(a). The landfills,
LF01, LF02, LF06, and, potentially, LF04 will be addressed in accordance with state of Alaska Solid
Waste Regulations under 18 A AC 60.
14.2 Recommended Limited Action Sites
• Groundwater constituents in five of the source areas (WP45/SS57, ST56, SS61, and DP25) exceed
maximum contaminant levels. These source areas are isolated, have no significant contamination or
have inaccessible residual contamination in the vadose zone, and are characterized by a stable plume
configuration. In the case of DP25, the plume is limited to an active tank farm. Action for these
source areas is limited to continued groundwater monitoring and restrictions on the use of the
groundwater.
Five of the source areas (WP45/SS57, ST56, SS61, and DP25) will receive limited action
including:
• Monitor the groundwater to evaluate contaminant levels and identify changes to contaminant plume
configuration until remediation levels are achieved.
• For groundwater at ST56, wellhead treatment using carbon adsorption or air stripping will be
applied, as appropriate, to prevent human exposure to contaminants above regulatory levels.
• If future developments in bioventing technology make implementation practical at DP25,
installation of a bioventing system will be re-evaluated at that time.
• Institutional controls to prevent exposure to contaminated groundwater. In the event of base
closure, any remaining contaminated sites will be addressed in accordance with CERCLA
Section 120.
Institutional controls would be used to prevent human exposure to contamination remaining at the
source areas at concentrations above state or federal regulatory levels or health-based risk levels.
Specific controls would include restrictions limiting access to the source areas, and administrative
controls to limit groundwater use and future land use. Access restrictions, including such measures as
permanent markers would be used to prevent direct human exposure to contaminants. Groundwater
restrictions would be implemented by placing written notification in the base directives prohibiting the
use of contaminated groundwater. In addition, all existing and any new wells located within the area of
contamination shall be locked to prevent unauthorized use.
The administrative controls for limiting future land use would include placing written notification
of these remedial actions in the base land use master plan. The notification shall prohibit any activity
that would disrupt aspects of the engineered controls. A copy of the notification would be provided to
any prospective transferees of the property and would be included in any transfer documents, including
deeds, in the event that the Air Force releases control of the affected property. The Air Force shall
provide EPA and the state with written verification that notification(s) have been implemented.

14.2.1 Source Area ST56 (OU 3}
Groundwater monitoring/institutional controls constitute the selected remedy for source area ST56.
The limited action at ST56 includes supplying drinking water, applying wellhead treatment as applica-
ble, and monitoring groundwater from the water supply well and existing monitoring wells. Subsur-
face treatment of the groundwater was not selected, because of the complex hydrogeology of the
fractured bedrock; the limited extent of the contamination in a remote, restricted area of the base; and
the reliability of available institutional controls to restrict the use of the contaminated well.
14.2.2 Source Area WP45/SS57 (OU 3)
Alternative 2, Groundwater Monitoring/Institutional Controls, has been determined to be the most
appropriate remedy for source area WP45/SS57. Soil and groundwater investigations previously
indicated that groundwater posed a risk to human health or the environment and that residual
contamination in the soil could be acting as a source of continuing groundwater contamination.
However, data from a report presented by the Utah Water Research Laboratory (UWRL), collected
during an independent study of WP45/SS57, indicates that soil contamination is contained around Well
45MW08 and rapid soil contaminant degradation is apparently occurring in the immediate vicinity of
that well. In addition, groundwater contamination appears to have reached a steady-state concentration
and distribution. The proposed alternative at WP45/SS57 was to implement SVE and bioventing in
addition to groundwater monitoring and institutional controls. The selected alternative, groundwater
monitoring/institutional controls, is significantly different from the proposed alternative. The reason
for changing the remediation alternative for WP45 and SS57 is explained in Section 16.0.
Fire Well C is located in source area WP/57 and is currently connected to the base water supply
system. Institutional controls would also apply to this well to prevent use of the contaminated
groundwater in a manner that would pose an unacceptable risk to human health or the environment.
14.2.3 Source Area SS61 (OU 3)
Alternative 2, Groundwater Monitoring/Institutional Controls, has been determined to be the most
appropriate remedy for source area SS61.
The source of solvent contamination at SS61 was a dry well on the south side of the vehicle
maintenance shop. The dry well and surrounding soils were excavated and backfilled. Soil and
groundwater investigations indicate that soil above the water table does not pose a significant risk to
human health or the environment. Groundwater beneath the vehicle maintenance shop is contaminated
with solvent. This plume is limited to the area beneath the building and slightly north beneath the
asphalt driveway in front of the building. The majority of the remaining contaminated soil is located
below the water table. Therefore, removing this soil would be difficult and of limited usefulness in
decreasing timeframes to meet RAOs.
Because of the limited access to the groundwater beneath the building, the action proposed is
limited to preventing the use of groundwater and to monitoring the plume to ensure that it does not
move from beneath the building. If the groundwater contamination is shown to be moving from
beneath the building at concentrations that would pose an unacceptable risk to human health or the
environment, the need for cleanup action will be reevaluated.

OUs 3, 4, and 5 Record of Decision Eielson AFB
14.2.4 Source Area DP25 {OU 4)
Alternative 2, Groundwater Monitoring/Institutional Controls, has been determined to be the most
appropriate remedy for source area DP25. Currently, all contamination at DP25 is contained within
the tank complex berm. The proposed alternative at DP25 is to monitor the groundwater and imple-
ment institutional controls. To comply with other state and federal programs, the secondary con-
tainment requirement of 18 Alaska Administrative Code 75, the bulk storage fuel tanks will be
upgraded with impervious liners in the diked areas. The upgrade project is scheduled to be completed
by the state deadline of January 1997. During the installation of the liners, approximately 0.3 m
(12 in.) of fuel-contaminated soil from within the berms (21,400 m3 or approximately 28,000 cu yd)
will be excavated. Although the liner is being emplaced to contain possible future fuel spills, it will
also serve to prevent infiltration of fuel into the soil, which would otherwise contribute to the spread of
contamination at this site.
If monitoring indicates any migration of contaminants outside the tank complex berm in the future,
trenches will be emplaced outside the berm to capture any migrating fuel. In addition, if nature
developments in bioventing technology make implementation practical at DP25, installation of a
bioventing system will be re-evaluated at that time.
14.3 Recommended Treatment Action Sites
Five source areas in OUs 3, 4, and 5 will require active remediation. Based upon CERCLA
requirements, the detailed analysis of the alternatives using the nine EPA criteria, and public
comments, the U.S. Air Force, ADEC, and EPA have determined the alternatives that are the most
appropriate remedies for each source area. Table 14.1 summarizes the selected remedy for each source
area. These remedies were selected as a result of the comparative analysis of the alternatives against
the nine EPA criteria. Additional discussion about the alternatives selected for each source area is
included in the following subsections.
Cleanup alternatives will be implemented using a phased approach, where design data gathering
and ongoing monitoring will continue to be evaluated to confirm the appropriateness of the selected
remedy or, once a remedy is implemented, to determine the effectiveness of the technology. This
phased approach will accommodate needed selected remedy or system modifications.
14.3.1 Source Area DP44 (OU 3)
The selected remedy for DP44 is soil vapor extraction/groundwater monitoring/institutional
controls. This alternative was chosen because of its effectiveness for treating chlorinated solvents that
are found at this source area and because it is believed that SVE will reduce risk to human health and
the environment sooner than monitoring and institutional controls alone. Groundwater extraction and
treatment/SVE is not the preferred alternative because of its difficult implementation, and because
biodegradation, dispersion, dilution, and adsorption appear to be effectively containing and degrading
the contamination.
The primary components of the selected remedy are:
• Install a soil vapor extraction system to remove solvent contamination in soil that is posing a threat
to groundwater through leaching.
FINAL 14.5 September 1995
-------
Eielson AFB OUs 3, 4, and 5 Record of Decision
• Implement institutional controls, as described, to prevent exposure to contaminated groundwater.
In the event of base closure, any remaining contaminated sites will be addressed in accordance with
CERCLA Section 120.
• Monitor the groundwater to evaluate contaminant levels and identify changes to contaminant plume
configuration until remediation levels are achieved.
It may become apparent, during the design phase, implementation, or operation of the SVE system
that solvent and fuel-related compounds in the soil and groundwater have .declined or have fallen below
levels that would pose an unacceptable risk. In such cases, the system performance standards or the
remedy may be re-evaluated to allow for the contaminants to naturally degrade.
14.3.2 Source Area SS35 (OU 4)
A combination of Alternative 3 (Soil Cover) and Alternative 4 (Possible Removal of Drums) has
been determined to be the most appropriate remedy for source area SS35. The placement of a clean
soil cover is designed to prevent contact with pesticide-contaminated soil and to prevent runoff of
contaminated soil into Garrison Slough. The buried drums will be left in place and the groundwater,
surface water, sediments, and aquatic organisms monitored, as appropriate. At this time, excavation of
the contaminated soil and drums is not considered cost-effective.
The cover alternative focuses on minimizing DDT migration into Garrison Slough and eliminating
the surface soil exposure pathway. The cover is proposed for those areas where DDT has been
detected above the risk-based levels in the surface soil. The soil cover is primarily for the purpose of
limiting the migration of contaminants into Garrison Slough and to prevent direct soil contact and
ingestion by the base personnel and ecological receptors.
The primary components of the selected remedy are:
• Installation of a soil cover over the surface soil contamination to prevent direct contact by humans,
animals, and surface water runoff into Garrison Slough.
• Removal of drums in the future, if it is determined that they are a continuing source of
contamination.
• Monitoring of surface water, sediments, and aquatic organisms in this area, as required to verify
effectiveness of the cover and monitoring of the groundwater to verify that levels remain below
acceptable screening levels.
14.3.3 Source Area ST58 (OU 4)
Alternative 3, an in situ alternative consisting of bioventing/groundwater monitoring/institutional
controls, has been determined to be the most appropriate remedy for source area ST58. This alterna-
tive will reduce the fuel source in the soils through degradation of fuel hydrocarbons, and will thus
reduce the risk to human health and the environment sooner than with monitoring and institutional
controls alone. At present, no proven method is known for removing lead from groundwater at a
reasonable cost in a reasonable amount of time. However, a treatability test is being performed at
another site at Eielson AFB to determine the fate and transport of lead and the most viable option for
extraction and treatment, if warranted. Results from this test will be used to further evaluate lead
remediation at ST58. Groundwater extraction/bioventing (Alternative 4) is not the preferred alternative
September 1995 14.6 FINAL
-------
OUs 3, 4, and 5 Record of Decision Eielson AFB
because of its difficult implementation, and because biodegradation, dispersion, dilution, and.
adsorption appear to be effectively containing and degrading the contamination.
This alternative will reduce the long-term source of contamination by preferentially encouraging
the removal of contaminants from the soil through bioventing. Groundwater action will consist of
natural attenuation, institutional controls, and monitoring.
The primary components of the selected remedy are:
• Installation of a bioventing system to remove fuels contamination in the soil that poses a threat to
groundwater through leaching. This system may include air injection within the upper part of the
groundwater table and smear zone to volatilize and promote bioremediation of the contaminants.
The system may also include air extraction if deemed appropriate.
• Institutional controls to prevent exposure to contaminated groundwater. In the event of base
closure, any remaining contaminated sites will be addressed in accordance with CERCLA
Section 120.
• Monitor the groundwater to evaluate contaminant levels and identify changes to contaminant plume
configuration until remediation levels are achieved.
14.3.4 Source Area LF03/FT09 (OU 5)
Alternative 4, Soil Cover/Composite Cap/Groundwater Monitoring/Institutional Controls, has been
determined to be the most appropriate remedy for source area LF03/FT09. FT09 is considered
together with LF03, because FT09 is completely contained within LF03.
This alternative was chosen because it is believed that a soil cover/composite cap will be more
protective of human health and the environment than will monitoring and institutional controls alone.
Groundwater monitoring will be performed at the edge of the waste management area to detect any
movement of contaminants.
The cap alternative focuses on eliminating the threat of direct contact with buried landfill debris,
and on soil contamination and monitoring of groundwater at the edge of the waste management area to
ensure that federal and state standards are met.
The primary components of the selected remedy are:
• For the portion of the landfill where disposal occurred before 1980, RCRA Part 264 is relevant and
appropriate. Currently, no groundwater at the edge of the waste management area exceeds regula-
tory levels; the residual contamination poses a direct contact threat. A cover to address the direct
contact threat will be installed and maintained in accordance with relevant and appropriate require-
ments of Part 264. Groundwater at the landfill will continue to be monitored, as appropriate, to
verify that contaminant concentrations, if any, remain within acceptable screening levels.
• For the portion of the landfill where disposal occurred after 1980, RCRA Part 264 is applicable.
The final cover will be constructed to: (1) provide long-term minimization of migration of liquids,
(2) function with minimum maintenance, (3) promote drainage and minimize erosion, (4) accom-
modate settling and subsidence, and (5) have a permeability less than or equal to the natural

subsoils present. Post-closure care, including maintenance and monitoring, will be conducted in
accordance with 40 CFR 264.117 and 264.228(b).
• Institutional controls will be implemented to restrict land use. In the event of base closure, any
remaining contamination will be addressed in accordance with CERCLA Section 120.

15.0 Statutory Determinations
The selected remedies meet the statutory requirements of Section 121 of CERCLA, as amended by
SARA, and to the extent practicable, the National Contingency Plan. The evaluation criteria for
compliance with these statutory requirements are discussed in this section.
15.1 Protection of Human Health and the Environment
The selected remedies protect human health and the environment through removal of the sources of
groundwater contamination. Institutional controls will eliminate exposure to contaminated groundwater
until state and federal standards are achieved. Groundwater monitoring will track the extent of contam-
ination above the MCL. The selected remedy will reduce risks to within the 10"4 to 10~6 range for
carcinogens and hazard indexes will be less than one. No unacceptable short-term risks or cross-media
impacts, resulting from implementation of the remedy, are present that cannot be readily controlled.
15.2 Attainment of Applicable or Relevant and Appropriate
Requirements of Environmental Laws
CERCLA specifies that remedial actions must attain standards that are defined by EPA and ADEC
as applicable or relevant and appropriate requirements (ARARs) for Eielson AFB, unless a waiver is
obtained. The selection process for remedial actions may also take into account the to be considered
(TBC) criteria, if ARARs do not address a particular situation. These criteria may include nonenforce-
able criteria, advisories, or guidance issued by federal or state agencies that are not legally binding but
are considered, if appropriate, in developing remedial action objectives and PRGs.
The selected remedies will comply with all substantive requirements for ARARs of federal and
State of Alaska environmental and public health laws.
15.2.1 Applicable or Relevant and Appropriate Requirements
The remedy chosen for each set of source areas will comply with all action-, chemical-, and
location-specific ARARs.
15.2.2 Chemical-Specific ARARs
The chemical-specific ARARs for remedial actions to be conducted at source areas in OUs 3, 4,
and 5 are:
• Maximum contaminant levels (MCLs) and maximum contaminant level goals (MCLGs) established
under the Safe Drinking Water Act for area groundwater that may be used as a drinking water
supply (40 CFR 141 and 18 AAC 80) (see Table 15.1).
• Federal ambient water quality criteria (AWQC) established under the Clean Water Act for the
protection of aquatic life in Garrison Slough and French Creek (see Table 15.1).

• Federal AWOC for the protection of human health from the consumption of fish from Garrison
Slough and French Creek (see Table 15.1).
• Alaska water quality standards under 18 AAC 70 for groundwater, designated beneficial use
Class (1)(A) for freshwater water supply, including the water quality standards for (l)(A)(i)
drinking, culinary, and food processing; (l)(A)(ii) agriculture, including irrigation and stock
watering; (l)(A)(iii) aquaculture; and (l)(A)(iv) industrial. At areas where the selected remedy is
active remediation, treatment will continue until MCLs are consistently attained. Natural
attenuation is expected to meet the petroleum requirements of 18 AAC 70.
• Alaska water quality standards for fresh waters (i.e., fresh surface water), designated beneficial use
Class (1)(A) for fresh water supply, Class (1)(B) for fresh water recreation, and Class (1)(C) for
growth and propagation of aquatic life and wildlife. The surface water quality standards include
those for (l)(A)(i) drinking, culinary, and food processing; (l)(A)(ii) agriculture, including irriga-
tion and stock watering; (l)(A)(iii) aquaculture; and (l)(A)(iv) industrial; (l)(B)(i) contact
recreation; (l)(B)(ii) secondary recreation; (1)(C) growth and propagation of fish, shellfish, other
aquatic life, and wildlife (18 AAC 70.020).
• Alaska Oil Pollution Regulations (18 AAC 75)
Under the Alaska Oil Pollution Regulations, responsible parties are required to clean up oil or
hazardous releases. The U.S. Air Force has proposed a calculation of soil cleanup levels,
based on the findings in the baseline risk assessment (U.S. Air Force 1995b) and a method-
ology using the EPA SESOIL and AT123D models (Anderson 1992). The proposed soil
cleanup levels are based on protecting groundwater in accordance with drinking water standards
and are specified in Table 15.2.
• Alaska Regulations for Leaking Underground Storage Tanks (18 AAC 78)
Under this regulation, the regional supervisor may identify alternative cleanup standards based
on the potential for leaching to groundwater. In accordance with this requirement, alternative
soil cleanup standards have been calculated (Table 15.2) based on the findings in the baseline
risk assessment (U.S Air Force 1995b) and a methodology using the EPA SESOIL and
AT123D models (Anderson 1992). The soil cleanup levels are based on protecting
groundwater in accordance with drinking water standards.
15.2.3 Location-Specific ARARs
The location-specific ARARs identified in the Draft RI for OUs 3,4, and 5 include:
• designation of the underlying aquifer as a sole source aquifer
• flood plain restrictions
• wetland protection under the Clean Water Act.
Remedial action at source areas within OUs 3,4, and 5 must consider remediation of contaminated
groundwater. Because the aquifer has been identified, but not designated, by the state as the sole
source of drinking water supply in the Eielson AFB area, prevention of further water quality deteriora-
tion and restoration of water quality to achieve state and federal water quality and drinking water
standards are primary objectives of remediation.

OUs 3, 4, and 5 Record of Decision
Eielson AFB
Remedial action at source areas within a designated flood plain must be designed to avoid adverse
effects, minimize potential harm, and restore and preserve natural and beneficial values of the flood
plain (40 CFR 6).
None of the source areas within OUs 3, 4, and 5 contain designated wetlands protected under the
Clean Water Act (USAF 1995a).
15.2.4 Action-Specific ARARs
Action-specific ARARs are technology- or activity-based requirements or limitations that relate to
specific remedial actions. Potential action-specific requirements are identified in Table 15.2. Com-
pliance with action-specific ARARs is evaluated as part of the detailed evaluation of alternatives
conducted in the FS process.

OUs 3, 4, and 5 Record of Decision
Because some of the contaminants identified in soils and groundwater within OUs 3, 4, and 5 can
be classified as RCRA hazardous wastes, RCRA requirements may be considered action-specific
ARARs for those source areas where placement or disposal occurs.
15.2.5 Criteria To Be Considered for Protectiveness
In addition to ARARs, federal and state criteria, policy, and guidance have been considered in
defining the appropriate level of protectiveness. The TBC criteria identified for source areas within
OUs 3, 4, and 5 are discussed in the following subsections.
Several methods, including the MEPAS model, were evaluated for determining soil cleanup levels.
Because of the limitations of using the MEPAS model for source areas with floating product or soil
contamination that occurs primarily in the smear zone, it was decided that a simpler approach would
probably provide more reliable results.

Eielson AFB
The generic leachate pathway soil cleanup levels were developed by the Oregon Department of
Environmental Quality using the EPA SESOIL and AT123D models. The cleanup levels are designed
to prevent contaminant levels in groundwater from exceeding a health-based safe drinking water level
through the leachate pathway. It was decided that although these numbers are based on higher precipi-
tation values than occur in the Fairbanks region, they would provide an adequate margin of safety for
cleanup of soils at Eielson. The methodology is described in Appendix A of the FS. The calculated
soil concentrations have been included in Table 15.3. However, it is expected that these levels will be
refined, if other levels are found to be protective of groundwater and as more site-specific and better
fate and transport data become available.
"RCRA ARARs: Focus On Closure Requirements," OSWER Directive 9234.2-04FS, October
1989, is a TBC when RCRA Subtitle C Part 264 is and ARAR.

15.3 Cost-Effectiveness
The selected remedies are considered cost-effective for remediation of the contaminated soils and
groundwater, because they have been determined to provide overall effectiveness proportionate to their
costs and duration.
15.4 Use of Permanent Solutions and Alternative Treatment
Technologies to the Maximum Extent Practicable
The selected remedies protect human health and the environment, comply with federal and state
requirements that are legally applicable or relevant and appropriate to the remedial actions, and are cost
effective. The remedies use permanent solutions and alternative treatment (or resource recovery)
technologies to the maximum extent practicable and satisfy the statutory preference for remedies that
employ treatment that reduces toxicity, mobility, or volume as a principal element.
15.5 Preference for Treatment as a Principal Element
For source areas DP44 and ST58, the selected remedy includes treatment to address the soil
contamination which is the principal threat posed by conditions at the site.

Eielson AFB Oils 3, 4, and 5 Record of Decision
For source areas WP45/SS57, ST56, SS61. DP25, SS35, and LF03/FT09, the selected remedy
does not include treatment because the contamination does not meet the definition of a principal threat,
as defined in the preamble to the NCP and the contamination can be reliably controlled in place.

16.0 Explanation of Significant Differences
CERCLA Section 117(b) requires an explanation of any significant changes from the preferred
alternatives originally presented in the proposed plan. Based on recent sampling results, the selected
remedy for source areas WP45/SS57 is different than that presented in the proposed plan. The new
information indicates that another alternative from the proposed plan provides the best balance of
tradeoffs among the alternatives with respect to the nine evaluation criteria.
16.1 Proposed Alternative
The proposed alternative for WP45/SS57 presented in the Proposed Plan for Operable -Units 3, 4,
5, and Other Areas (May 1995) was Alternative #3: soil vapor extraction (SVE)/groundwater moni-
toring and institutional controls for WP45, and bioventing/groundwater monitoring and institutional
controls for SS57. SVE was chosen for WP45 because it is an effective method of remediation for
solvents in unsaturated soils. It was believed that SVE would reduce the risk to human health and the
environment sooner than with monitoring and institutional controls alone. Bioventing was the pre-
ferred alternative for SS57, because it may be an effective method for treating the fuel-related
contaminants in the smear zone, where most of the contamination had been found. These proposed
alternatives were based primarily on information presented in the OU 3,4, and 5 Remedial Investi-
gation, the Baseline Risk Assessment, and the Feasibility Study (U.S. Air Force 1995a, 1995b, and
1995c).
16.2 Significant Changes
The selected remedy for both sites WP45 and SS57 has been changed to Alternative #2: ground-
water monitoring and institutional controls.
16.3 Reason for Change
An independent study of natural attenuation by Utah Water Research Laboratory (UWRL), Utah
State University, has been conducted concurrently with the remedial investigation at WP45/SS57. A
meeting was held 6 July 1995, during which UWRL presented their findings and modeling of site data
collected at WP45/SS57. The soil and groundwater contamination exists at this site in the form of low-
level sorbed species and dissolved contaminant mass. Currently, no evidence of residual dense non-
aqueous phase liquid (DNAPL) is present within the source area at the site; it also does not appear that
any residual fuel material exists in the form of light nonaqueous phase liquid (LNAPL). The contami-
nation is adsorbed and contained or in a dissolved phase and not accessible for source removal or
treatment. UWRL focused its study on evaluating the current extent of the dissolved TCE plume,
investigating evidence of TCE degradation existing throughout the site in the form of anaerobic
dechlorination intermediate products, and evaluating the likelihood of biological mediated reactions
based on mass balance estimates and known stoichiometric relationships for these anaerobic trans-
formation processes.
FINAL 16.1 September 1995
-------
Eielson AFB OUs 3, 4, and 5 Record of Decision
UWRL field data collection confirmed earlier findings reported by PNL. Low levels of soil con-
tamination (< 1 ppm TCE in all samples), an apparently contained groundwater plume (particularly
benzene), no free product, and no vinyl chloride detected through DCE was found to be present. New
findings include further evidence of TCE anaerobic dechlorinatiqn with ethylene and large distribution
of DCE product, significantly lower BTEX than previously reported, and rapid transportation of con-
taminants in the immediate vicinity of monitoring well 45MW08 (suspected source area).
The relative rate and extent of contaminant migration was evaluated through the use of a conven-
tional 3-dimensional advective/dispersive groundwater model that incorporates groundwater flow,
contaminant sorption, and contaminant degradation to describe the downgradient movement within the
shallow aquifer over time. Model parameters that were not available or measured at the site were
estimated using representative literature values.
The results of the UWRL study suggest that groundwater movement from this site is relatively slow
(approximately 18 m/yr pore water velocity, with approximately 6 rn/yr retarded TCE groundwater
velocity based on measured field data). Additionally, with approximately 9 kg of TCE mass apparently
lost in the aquifer over a 2-year monitoring period, it appears that TCE degradation is occurring at a
first order degradation rate of approximately 0.00027/d (0.027%/d), yielding a TCE half life of
approximately 7 years. With these values of contaminant velocity, apparent degradation rate, and an
estimated source configuration based on model calibration, the remaining source of TCE contamination
is predicted to be exhausted in another 7 years, with the subsequent groundwater plume generated from
this source being attenuated within the aquifer to below regulatory limits of 5 ng/L within 70 years,
and approximately 500 m of the source (Figures 16.1 and 16.2). Comparatively, it was estimated that
by implementing SVE, coupled with bioventing, groundwater monitoring, and institutional controls,
soils at WP45/SS57 would attain ARARs within 1 to 4 years, and groundwater would take more than
100 years to attain MCLs (U.S. Air Force 1995c). The data presented by UWRL indicates that active
remediation of source areas WP45/SS57 will not significantly increase the rate of contaminant
degradation from that now occurring naturally.
UWRL also evaluated a source removal scenario. Figures 16.3 and 16.4 graphically show the
response of the dissolved TCE groundwater plume over time to complete source removal at source area
WP45/SS57. At At - 60 years (that is, 60 years after source removal) the TCE plume centerline con-
centration is still predicted to be above its current MCL 5 /xg/L. TCE centerline concentrations would
drop below the MCL for At - 70 years. At At - 70 years, the maximum centerline concentration was
predicted to be 3 pg/L at a distance of 430 to 450 m downgradient from the source. These results,
along with the estimate of remaining source lifetime, suggest that source removal alone would be
expected to reduce the lifetime of the TCE plume by only approximately 7 years, or 10%, indicating
that source removal would not be an effective approach for expediting remediation at source areas
WP45/SS57.
In summary, the findings presented by UWRL support several conclusions at WP45/SS57. It is
apparent the BTEX plume is contained (see Figures 16.5 and 16.6). The TCE groundwater plume has
reached steady-state conditions, and plume containment and TCE degradation are observed (see Fig-
ures 16.7 through 16.10). A limited extent of containment distribution was found near the source
areas. SVE and bioventing would have limited effectiveness in comparison with the rate of degradation
achieved by natural processes.

Responsiveness Summary
A. OVERVIEW
The proposed cleanup alternatives considered by the U.S. Air Force, Alaska Department of
Environmental Conservation (ADEC), and U.S. Environmental Protection Agency (EPA) were
presented to the public in a proposed plan (U.S. Air Force 1995d) and discussed in a public meeting on
31 May 1995. This plan proposed the preferred alternative to address contamination in the soil and
groundwater at Operable Units 3. 4. 5. and other areas. The preferred alternative restricts ground-
water use in the contaminated areas through institutional controls. The controls will remain in effect as
long as the contamination persists.
Generally, public comments supported the plan as the best compromise among the clean up
options.
These sections follow:
• Background on Community Development
• Summary of the Comments Received During the Public Comment Period and USAF Responses
- Part I: Summary and Response to Local Community Concerns
- Part II: Response to Specific Technical and Legal Questions
• Remaining Concerns
B. BACKGROUND ON COMMUNITY INVOLVEMENT
Prior to the addition of Eielson AFB to the EPA National Priority List in 1989, the community was
offered little opportunity for involvement in environmental activity. From 1982 until 1989, the USAF
used the Installation Restoration Program (IRP) to identify potential contaminated areas and investigate
what remedial actions might be required. This process was purely technical and did not evaluate
community concerns in the decision-making process. However, after signing a Federal Facility Agree-
ment with the State of Alaska and the EPA in 1991, the Air Force began its Superfund clean up
program, which does include extensive community involvement.
A technical Review Committee (TRC), established in 1992, included three representatives from the
community (selected by local officials and the University of Alaska Chancellor), industry representa-
tives, and environmental representatives. Many of the TRC participants are members of the profes-
sional public. The TRC was converted to a Restoration Advisory Board (RAB) in the Spring of 1995.
Three community representatives were selected as RAB co-chairpersons, one each from the communi-
ties of Salcha, Moose Creek, and North Pole, Alaska. The RAB met on April 27, 1995 to review
OU 3,4, and 5 information and again on 8 June 1995 during the comment period.

-------
Eielson AFB OUs 3, 4, and 5 Record of Decision
The proposed plan and the public meeting for OU 3. 4. and 5 were advertised twice in each of two
local newspapers. In addition, more than 3500 copies of this notice were added as an insert in the base
newspaper and delivered to every home in. the Eielson AFB housing area on May 19, 1995. Proposed
plans were mailed to more than 150 people on the clean up mailing list on May 16, 1995. In addition,
copies of the plan were delivered to various information repositories, the Alaska Department of Fish
and Game, North Pole City Hall, Moose Creek Fire Department, and several local stores and busi-
nesses. Flyers were placed on store bulletin boards in the Moose Creek and North Pole communities.

C. SUMMARY OF COMMENTS RECEIVED DURING THE PUBLIC
COMMENT PERIOD AND USAF RESPONSES
The public comment period on the Operable Unit 3,4, and 5 Proposed Plan extended from May 18
through June 17, 1995. Comments received during that period are summarized in Parts I and II.
Part I addresses nontechnical concerns; Part II responds to technical and legal questions. Each part is
grouped by similar topics.
September 1995 RS.2 FINAL
-------
OUs 3, 4, and 5 Record of Decision Eielson AFB
PART I - Summary and Response to Local Community Concerns
- Topic: Environmental Questions
- Public Comment: One person wanted to know how to get information on clean up work at Eielson,
and another asked to be added to the mailing list. A third caller asked for information about source
area LF04.
- USAF Response: The Air Force provided fact sheets on work opportunities and how to be
considered for this clean up work at Eielson. The mailing list was updated to include the names of
those people interested in the environmental clean up work at Eielson Air Force Base. A package of
information from the Administrative Record on LF04 was mailed to the interested person.
PART II - Response to Specific Technical and Legal Questions
- Topic: Alternatives Selection
- Public Comment: One person supported the cold mix asphalt process that was used to resurface
roads on base with materials recovered from source area SS39 in OU 4. The person commented this
procedure should be considered for any diesel-contaminated soil, or any other application where a waste
material can be treated and recycled into a useful product, instead of being thrown away.
- USAF Response: The Eielson clean up team appreciates this technology, as demonstrated by having
already used cold mix asphalt paving in local projects. The team will continue to consider this method
for future situations where this technology could feasibly be applied. The selected remedies for source
areas in OUs 3,4, and 5 do not include excavation and disposal for any petroleum contaminated soil;
therefore, this technology to recycle contaminated soil is not applicable for these areas.
D. REMAINING CONCERNS
- Topic: Transporting Contaminated Soils Through Moose Creek
- Public Comment: One person was concerned that dust from contaminated soil and heavy traffic to
transport the soil could create a risk for residents in Moose Creek. The soil is being transported to an
incinerator in Moose Creek. The caller said residents are worried about the potential for an accident
due to the poor condition of the narrow roadway between the base and the treatment facility. The caller
requested the trucks be diverted to a back road that leads directly from the base to the incinerator and
that avoids populated areas.
- USAF Response: The comment was routed through the RAB military co-chairman to the Support
Group commander. The contractor was advised of the safety concerns expressed by the area residents.
The trucks were directed to drive on the new Richardson Highway, this eliminating excessive traffic in
the Moose Creek community. The issue was also addressed at the RAB meeting in North Pole on 8
June 1995.
