I. Introduction
The purpose of a Five-year Review (FYR) is to evaluate the implementation and performance of a
remedy to determine whether the remedy is and will continue to be protective of human health and the
environment. The methods, findings, and conclusions of reviews are documented in FYR reports such as
this one. In addition, FYR reports identify issues found during the review, if any, and document
recommendations to address them.
The U.S. Environmental Protection Agency is preparing this FYR pursuant to the Comprehensive
Environmental Response, Compensation, and Liability Act Section 121, consistent with the National Oil
and Hazardous Substances Pollution Contingency Plan (40 CFR Section 300.430(f)(4)(ii)), and
considering EPA policy.
This is the fifth FYR for the Red Oak City Landfill Superfund Site (Site). The triggering action for this
statutory review is the signature date of the previous FYR report, which was signed on July 27, 2017.
This FYR has been prepared because hazardous substances, pollutants or contaminants remain at the
Site above levels that allow for unlimited use and unrestricted exposure.
The Site consists of one operable unit (OU), and is the only OU reviewed in this FYR. The purpose of
the remedial action at OU1 was to reduce or eliminate the threat of direct contact with, ingestion of, or
inhalation of materials which are associated with significant human health risks due to exceedance of the
EPA's risk management criteria for either the average or the reasonable maximum exposure scenarios.
Exposure to contaminated groundwater at the Site was determined to not represent a significant
exposure pathway.
The Red Oak City Landfill Superfund Site FYR was led by David Wennerstrom, EPA Region 7
remedial project manager. Additional EPA Region 7 participants included Ann Jacobs, human health
risk assessor; Catherine Wooster-Brown, ecological risk assessor; Randy Brown, hydrogeologist; Danny
Lyskowski, attorney; and Pam Houston, community involvement coordinator. The Iowa Department of
Natural Resources (IDNR) was represented by Matt Culp. A public notice of FYR initiation was posted
in November 2021 in the Red Oak Express Newspaper. Relevant entities, including the potentially
responsible parties (PRPs), were notified directly. The review began in August 2021.
Site Background
The Site occupies 40 acres in Montgomery County, Iowa, about 1.5 miles northwest of the city of Red
Oak (City) on the west bank of the East Nishnabotna River and on the east side of Parkwest Road, now
known as G Avenue. Red Oak is a community of approximately 6,300 residents. The Site occupies a
parcel of land approximately 40 acres in size on the west bank of the East Nishnabotna River within
Section 17, Township 72 North, Range 38 West. The Site was originally a limestone quarry which
operated from the late 1940s to the early 1960s. The city of Red Oak purchased the property in 1962 and
operated it as a landfill until it closed in April 1974. Wastes disposed of at the Site reportedly included
construction and demolition debris, tree pruning waste, municipal refuse generated by residents and
businesses, and industrial wastes from facilities in the Red Oak area. The industrial wastes disposed of at
the Site reportedly included toluene, methyl isobutyl ketone, tetrachloroethene (PCE), mineral spirits,
diacetone alcohol, and laminated paper containing approximately three percent mercurous chloride by
weight, related to the Union Carbide Corporation's production of dry cell batteries. Along with general
refuse, Uniroyal Incorporated disposed of approximately 3,000 pounds of drummed filter cake
containing approximately 430 parts per million lead.
1
-------
The Site was initially identified as a result of notification to the EPA by the Union Carbide Corporation
and Uniroyal, Incorporated. In September 1984, the EPA observed leachate seeping from the landfill
into the East Nishnabotna River and collected samples of groundwater, surface water, and sediment.
Analyses detected toluene, chlorbenzene, and 1,1,1-trichloroethane. Preliminary site investigation
activities were completed in 1983 and 1985. Based on findings of the investigations, the Site was
proposed for the National Priorities List (NPL) in 1984 and became final on the NPL in June 1986. In
1989, the EPA and the PRPs entered into a Consent Decree (CD) for performance of the Remedial
Investigation (RI)/Feasibility Study.
The Site is currently fenced and posted with warning signs, and the landfill waste is contained within the
fenced area under an impermeable cap. The landfill surface is vegetated primarily with grasses and
weeds; wooded areas are located along the river bank, adjacent to G Avenue and along the southern
boundary of the Site. The quarry pond west of the Site is privately owned and used for recreation,
including fishing and swimming. The East Nishnabotna River located along the eastern boundary of the
Site is used for fishing (Appendix B, Figure 2).

II. Response Action Summary
Basis for Taking Action
Hazardous substances released at the Site include aluminum, barium, cadmium, chromium, copper, lead,
manganese, mercury, nickel, silver, zinc, acetone, 1,2-dichloroethene (1,2-DCE), PCE, bis(2-ethylhexyl)
phthalate and polycyclic aromatic hydrocarbons (PAH). These contaminants were of concern primarily
in the surface soil and exposed waste. Exposure to soil and exposed waste are associated with significant
human health risks due to exceedance of the EPA's risk management criteria for either the average or
the reasonable maximum exposure scenarios. The carcinogenic risks were highest for exposure to soil
and waste due to the concentrations of carcinogenic PAHs. Non-carcinogenic hazards were highest for
exposure to soil and waste due to lead, manganese and cadmium. Exposure to contaminated
groundwater at the Site was determined to not represent a significant exposure pathway.
Response Actions
The Record of Decision (ROD) for the Site was signed on March 31, 1993. The remedial action
objectives (RAOs) were developed as a result of data collected during the RI to aid in development and
screening of remedial alternatives to be considered for the ROD. The RAOs for the Site were to:
• Reduce or eliminate the threat of direct contact with, ingestion of, or inhalation of materials
containing acetone, 1,2-DCE, PCE, toluene and other contaminants contained in soil and waste
buried at the Site;
• Reduce surface water infiltration through the buried waste materials to minimize the potential for
leaching of contaminants from the waste materials to groundwater and surface water;
• Control erosion of the river bank slope to minimize the potential for exposure of buried waste
materials; and
• Address potential exposure to increased contaminant levels in the future due to erosion of existing
surficial materials.
The major components of the remedy selected in the ROD include:
• Installation of an engineered low-permeability cap over the surface of the landfill;
• Construction of diversion and drainage structures to manage surface drainage resulting from the
reduced permeability of the landfill cover;
• Stabilization of the river bank slope by contouring and re-vegetation along with further study of the
stability of the slope;
• Access control provided by a perimeter fence around the landfill area;
• Institutional controls (ICs), including deed restrictions, to control future land use at the Site; and
• Long-term groundwater monitoring to evaluate the effectiveness of the remedy and ensure
groundwater contaminant levels remain protective.
An Explanation of Significant Differences (ESD) was issued on January 30, 1996. Based on a study by
the PRPs, the EPA determined that river bank slope shaping could be limited, the thickness of the
landfill cap could be reduced, the slope study and further stabilization measures could be eliminated, and
costs could be re-estimated. These changes were incorporated into the ESD.
3
-------
Status of Implementation
In a CD signed with the EPA on November 27, 1996, the PRPs agreed to perform the Remedial
Design/Remedial Action and pay past costs for cleaning up the Site. The RD was conducted in
conformance with the ROD, as modified by the ESD. The RD was approved by the EPA on July 28,
1997.
The remedial action was initiated on August 16, 1997. Initial construction activities were completed on
November 21, 1997. The PRPs were divided into three groups according to the obligations they took on:
• The construction parties, consisting of Eveready Battery Company, Inc. (Eveready) and its parent;
• A group of operation and maintenance (O&M) parties consisting of Magna International (Magna)
and the city of Red Oak; and
• A group of cash-out parties.
Construction of the remedy was initially thought to have been completed in November 1997. However,
areas of instability in both the landfill cap and the river bank slope were discovered in the spring of
1998. The cap was repaired in May 1998, and the slope was repaired in September 1998.
In February 1999, the dispute provision of the CD was invoked by Eveready, concerning the EPA's
declination to view the entire remedy as completed. A May 1999 site visit was set to inspect both the
slope and cap, but before this meeting occurred, it was discovered that the slope was unstable. It was
agreed that an inspection of the Site would be conducted in October 1999 to verify that there was an
adequate growth of new vegetation on the cap and slope.
The construction completion designation was achieved when the Preliminary Closeout Report was
signed on June 21, 2001. The EPA stated its intention to carefully monitor the landfill over the next
several winters to obtain more assurances that the slope would hold. After the slope was determined to
be adequate, the EPA certified completion of the remedy on November 19, 2002. The EPA issued a
Final Closeout Report on June 13, 2005. The Site was deleted from the NPL on September 26, 2005.
Institutional Controls
ICs are required for the Site. First, the state placed the Site on Iowa's Registry of Hazardous Waste
Disposal Sites, which prevents changes in land ownership or use without state approval. Second, under
the 1996 CD with the EPA, the site owners granted to the City an easement containing restrictive
covenants that limited future uses of the Site. A provision was also added to the CD in the event the City
became a site owner; the provision required the City to retain an easement, similar to the one in place
from the previous owners, if the City decided to sell the property.
When the original owner died, he gave the property to the City, which now owns the property. The deed
granting the property to the City, filed seven months after the CD became final, contains language which
acts as a deed notice and acknowledges the grantee's assumption (i.e., the City's assumption) of the
requirements of the CD concerning this real estate. Further, the listing of the Site on the Iowa Registry
of Hazardous Waste Disposal Sites is noted and recorded with Montgomery County (dated February 12,
1987).
In conjunction with IDNR, the EPA has proposed environmental covenants for the Site. Presently the
proposed environmental covenants are in review by the city of Red Oak. Once the environmental
4
-------
covenants are recorded, the Site will be deleted from Iowa's Registry of Hazardous Waste Disposal
Sites.
Systems Operations/Operation & Maintenance
Pursuant to the Monitoring, Operations and Maintenance Plan (MOMP), the primary O&M activities
include the following:
• Inspection of the landfill cap, drainage structures, and river bank slope with regard to vegetative
cover, settlement, stability, fencing, and monitoring well protection, including any necessary repairs;
• Annual reseeding to be done as necessary, as well as semi-annual mowing and noxious weed
control;
• Conducting groundwater and surface water sampling; and
• Sampling of landfill seeps occurring on the river bank slope.
The PRPs have been conducting monitoring and maintenance according to the MOMP. Since 2001, the
landfill cap, stabilized river bank slope, monitoring wells, fence and security structures, and drainage
structures have been inspected on an annual basis. Mowing of the landfill cap is done semi-annually and
re-seeding and noxious weed control is performed as needed.

IV. Five-year Review Process
Community Notification, Involvement & Site Interviews
A public notice was made available by a week-long advertisement in the Red Oak Express in October
2021, stating that a FYR had begun and inviting the public to submit any comments to the EPA. The
results of the review and the report will be made available via the EPA's internet-based information
repository, which can be accessed by the public through the following website:
https://semspub.epa.gov/src/collections/07/AR/IAD9806325Q9
During the FYR process, interviews were conducted to document any perceived problems or successes
with the remedy that has been implemented to date. The results of these interviews are summarized
below.
Interviews were conducted on October 26, 2021, at the Red Oak Superfund Site in Red Oak, Iowa. The
following individuals were interviewed: David Wennerstrom, EPA; Matt Culp, IDNR; Darren Paul and
Brad Wright, city of Red Oak; Joe Byce, Magna; and Gaylen Hiesterman, Atlas.
All interviewees stated that they had been well-informed about the Site's activities and progress and that
they had no concerns regarding the protectiveness of the Site. All interviewees expressed concern over
the steepness and stability of the slope, but all felt that the correct monitoring was being performed and
that there is no real risk associated with the slope. The City would like to see a beneficial reuse of the
Site; IDNR requested involvement in any discussions regarding site reuse. All interviewees agreed that
the remedy was effective and that the monitoring and inspection program in place was effective and
appropriate. The EPA and IDNR did not receive any communication from the public regarding
concerns, comments, or questions regarding the remedy during this FYR period.
Data Review
This FYR included a review of relevant information contained in a variety of site-related documents
addressing groundwater and surface water quality. Specific activities during this FYR period included
collection of surface water samples from two locations (one upstream and one downstream of the
landfill), seep samples collected from one seep located downslope of GW-02R near the river bank,
collection of groundwater samples from five monitoring wells, and collection of inclinometer data used
to monitor slope movement.
The annual Monitoring, Operation and Maintenance Report (MOMR, Appendix C) was reviewed from
2017 through 2020. The MOMRs included inspection of the landfill cap and drainage, sampling of the
existing monitoring wells, sampling of the intermittent seep present at the Site, sampling of surface
water in the East Nishnabotna River adjacent to the Site, and bank stability observations including visual
observations and readings from the subsurface inclinometer installed on the cap at the edge of the river
bank adjacent to monitoring well GW-02R. There are five monitoring wells at the site, GW-01
through GW-05. GW-02 was destroyed by bank instability in 2008 and was replaced by GW-02R. GW-
02R has been repeatedly dry or had insufficient water to sample since its installation. The inclinometer
INC-1 was installed in 2009 to measure subsurface movement of the slope beneath the inclinometer.
The 2020 sampling event identified concentrations of total 1,2-DCE and vinyl chloride in GW05 at 1.68
micrograms per liter (|ig/L) and 2.17 |ig/L, respectively. The vinyl chloride detection was slightly above
6
-------
the Maximum Contaminant Level (MCL) of 2 |ig/L, although a site-specific action level was not
established in the ROD. Throughout the monitoring period of 2001-2020, volatile organic compounds
(VOCs) have only been reported in monitoring well GW05. No trend is apparent for the detected VOCs.
The majority of the VOC analytes in MW-05 have historically been below laboratory detection limits.
Arsenic (total and dissolved) was detected above the ROD action level in groundwater samples in
several sampling events. No definitive trend is apparent for arsenic concentrations. Cobalt (total and
dissolved) was detected above the ROD action level at GW05 and is consistent with historical data
(stable trend). Iron (total and dissolved) and manganese (total and dissolved) were detected above the
ROD action level at GW03 and GW05. No trend is apparent for these concentrations.
For surface water, no VOCs were detected in surface water samples during 2020. Inorganic
concentrations that were anomalously high during 2019 returned to historical ranges during 2020,
supporting the interpretation that 2019 concentrations were caused by record flooding. Arsenic (total and
dissolved) was detected above the ROD action level at similar concentrations in upstream and
downstream samples, supporting the historical interpretation of an upstream source or background
concentrations.
The seep appeared downslope of GW02 after the bank instability events of 2008 and is intermittent in
nature seasonally, from no flow to approximately 0.5 gallons per hour. No VOCs or arsenic were
detected in the seep sample during 2020. Repeated sampling of the seep has demonstrated that it does
not appear to be a significant source of contaminants to the East Nishnabotna River.
Visual observations of the slope markers indicate that the bank has stabilized. Inclinometer Profile A
included in the 2020 MOMR has returned towards baseline values, supporting the 2019 interpretation of
swollen soils as a result of record precipitation and flooding. Profile B resembles the 2019 departure
from historical values, possibly indicating a new baseline caused by settlement of soils in moderate
drought conditions after record flooding. Continued monitoring of Profile B is necessary to determine
the cause of the 2019 and 2020 shift. The 2020 MOMR concluded that the inclinometer deflections are
not considered to be caused by deep-seated movement of the slope subsurface, which corroborate the
visual observations of bank stability.
Tables of analytical results for all sampling activities (seep, surface water, and groundwater) are
presented in the 2020 MOMR in Appendix C.
Site Inspection
An inspection of the Site was conducted on October 26, 2021. The purpose of the inspection was to
assess the protectiveness of the remedy. A record of the site inspection titled "LSASD Field Activity
Report" can be found in Appendix C. In attendance were:
• David Wennerstrom, EPA Region 7,
• Randy Brown, EPA Region 7,
• Matt Culp, IDNR,
• Brad Wright, City Administrator,
• Darren Paul, City of Red Oak,
• Joe Byce, Magna, and
• Gaylen Hiesterman, Atlas.
7
-------
The site inspection assessed the overall maintenance of the Site, the condition of the side slope adjacent
to the East Nishnabotna River, the surface integrity of the groundwater monitoring wells and
inclinometer (including well pads, protective covers, name plates and locks), and perimeter fencing.
The site inspection found the landfill cover to be well maintained and the remedy functioning as
intended by the ROD and as modified by the ESD. No deficiencies in the landfill cover or surface water
drainage structures were noted. The only potential area of concern is associated with the slope stability,
which is being monitored. The ICs in place appear to be working properly. No activities were observed
that have violated the ICs. The landfill cap, slope, and surrounding areas were undisturbed, and no uses
of groundwater or surface water that would result in new exposures were observed. No opportunities
were identified to optimize the monitoring or O&M.
V. Technical Assessment
Question A: Is the remedy functioning as intended by the decision documents?
Question A Summary:
The remedy appears to be functioning as intended by the decision documents. No significant increases in
concentration trends in groundwater, surface water, or the seep concentrations were identified during
this FYR period. The bank slope from the landfill cap to the East Nishnabotna River appears to have
stabilized.
Remedial Action Performance
The landfill cap is being maintained and no significant erosional features were identified during the FYR
site inspection. The surface drainage was in good condition, no drains were obstructed, and no standing
water or obstructed drains were present even after a rainfall of several inches before the site inspection.
Monitoring wells were locked and in good condition; however monitoring wells GW-03 and GW-04
have cracks in the protective apron (photos included in Appendix C). The well aprons were replaced in
2022.
The bank appears to have stabilized, and the observations during the site inspection are consistent with
the 2020 MOMP that no further significant bank slumping has occurred. Native trees and grasses as well
as some of the planted trees are well established along the slope, which will add to future stability. The
seep concentrations appear to indicate that it is not a significant source of surface water contamination.
System Operations/O&M
Findings from the FYR site inspection and a review of MOMRs since the last FYR indicate that the
landfill cover has been well maintained and that the monitoring and maintenance requirements outlined
in the approved MOMP have been followed. The site inspection revealed no deficiencies in the landfill
cover or surface water drainage structures that would warrant a change in the system's operation or
O&M activities. O&M procedures have been properly implemented and are being sufficiently
maintained to ensure current and long-term protectiveness of the remedy.
8
-------
Implementation of Institutional Controls and Other Measures
ICs at the Site consist of a deed notice that refers to the restriction and responsibilities placed on the
owner by the CD. The Site is also listed on Iowa's Registry of Hazardous Waste Disposal Sites pursuant
to Iowa Code 455B.426. The state registry listing prohibits the sale or significant change in use of the
property without the approval of the director of IDNR. This is typically filed with the county recorder to
add a notice to the deed that the Site is on the registry. The listing of the Site on the Iowa Registry of
Hazardous Waste Disposal Sites was recorded in Montgomery County on February 12, 1987. Also, 567
Iowa Administrative Code (IAC) Chapters 43 and 49 prescribe minimum lateral distances for placement
of public and private wells from solid waste landfills and sanitary landfills.
Access controls at the Site, fencing and a locked entry gate, remain in place and were in good condition
at the time of the FYR site inspection. These controls appear to be effective as there have been no
reports of vandalism or trespassing on the Site.
In addition to the institutional and access controls, an annual groundwater use review is conducted. This
consists of a driving survey of the area generally within a two-mile radius of the Site to identify new
construction or development within the area. Due to the absence of rural water systems in the area, it is
inferred that such development would also likely include installation of a well for water supply
purposes. The Montgomery County Environmental Services Department is also contacted for updated
well registration information in the area. This department is responsible for issuing well construction
permits within the county.
The ICs in place are effective in preventing exposure, and no activities were observed that have violated
the ICs or question the need for additional ICs. The landfill cap, slope and surrounding areas were
undisturbed, and no uses of groundwater or surface water that would result in new exposures were
observed. The requirements and monitoring frequency outlined in the MOMP are acceptable to assess
the protectiveness of the remedy. O&M procedures have been properly implemented and are being
sufficiently maintained to ensure current and long-term protectiveness of the remedy.
Question B: Are the exposure assumptions, toxicity data, cleanup levels, and remedial action
objectives (RAOs) used at the time of the remedy selection still valid?
Question B Summary:
Human Health Risk Assessment
The groundwater action levels remain a mix of Health Advisory Levels (HALs), Negligible Risk Levels
(NRLs), maximum contaminant levels (MCLs), and EPA tap water screening levels. There have been no
changes to the action levels during this FYR period.
There have been no changes in exposure assumptions, toxicity data, cleanup levels, or remedial action
objectives that call into question the protectiveness of the remedy.
The 2018 monitoring report did not indicate groundwater exceedances of VOCs, but did note
groundwater exceedances of action levels for arsenic, cobalt, and manganese (ATC, 2018). Exceedances
of action levels in surface water samples were noted for several metals in the 2019 monitoring report
(ATC, 2019) for aluminum, arsenic, cadmium, and manganese. Water samples from the seep indicated
exceedances of action levels for aluminum, arsenic, and manganese in 2019, likely due to significant and
9
-------
persistent spring flooding. The monitoring report for 2020 indicated that surface water concentrations
returned to detections below action levels (ATC, 2020).
Ecological Risk Assessment
The RAOs remain valid. Federal Ambient Water Quality Criteria and Iowa Surface Water Quality
Standards were designated by the ROD as Applicable or Relevant and Appropriate Requirements
(ARARs) to be used to screen water at the seeps entering the river and in the surface water of the river.
According to the latest MOMR (ATC, 2020), site surface waters contained no detections of any VOCs
in either the upstream or downstream samples. In 2020, the heavy metals in surface water results are all
less than the action levels. The 2020 MOMR did note that after a 2019 flooding event, there were some
elevated concentrations of metals in 2019 surface water sample results (and there had not been elevated
concentrations since 2003). Those elevated concentrations returned to below the site action levels in
both the spring and fall sampling events in 2020. Therefore, it was concluded that the elevated
concentrations of metals in surface water samples were an anomaly and a result of record flooding in
southwest Iowa in 2019.
Changes in Standards and TBCs
The ROD did not identify chemicals of concern (COCs) or specific cleanup goals based on risks or
ARARs. The ROD indicated that groundwater data were to be compared instead to a set of "action
levels", exceedances of which would trigger an evaluation, investigation, or remediation, if needed.
These action levels for groundwater are designated as the first values obtained from a hierarchy of
values set out in 567 IAC 133.2. Values in the hierarchy include the EPA lifetime HALs, the EPA
NRLs, federal primary enforceable MCLs, and other credible sources of risk-based screening levels
(RSLs) (e.g., EPA Regional Screening Levels), in that order.
Federal Ambient Water Quality Criteria and Iowa Surface-Water Quality Standards were designated by
the ROD as ARARs to be used to screen water at the seeps entering the river and in the surface water of
the river. These values take into account the types and limitations of exposures likely to occur in surface
water at the Site and address both human and ecological risks, since groundwater may be discharged to
the river. However, the rate of groundwater discharge is considerably lower than the flow rate of the
river, resulting in substantial dilution of any contaminants that may be discharged from the Site. Thus,
an exceedance of any of these values would not automatically call the effectiveness of the remedy into
question.
There were no changes to standards or TBCs for this FYR period.
Changes in Toxicity and Other Contaminant Characteristics
Since this Site is a landfill, characterization of contamination in the landfill and identification of COCs
would have been problematic. The landfill cap and restriction on placement of drinking water wells
precludes direct contact by any receptor with chemicals in the landfill. Without contact to the
groundwater, there are no risks.
Although there have been changes in the toxicity values for some of the site COCs since the time of
remedy selection, these changes do not impact the protectiveness of the remedy. As described above, all
of the action levels are based on HALs, NRL, MCLs, and some RSL tapwater screening levels, and all
remain valid.

-------
Changes in Risk Assessment Methods
Human Health and Ecological Risk Assessment
There have been no changes in risk assessment methodologies since the last FYR that could affect the
protectiveness of the remedy.
Changes in Exposure Pathways
Human Health Risk Assessment
There have been no changes in exposure pathways since the last FYR that would impact human health
or the effectiveness of the remedy.
Land use at the Site, which is undeveloped rural land in a primarily agricultural area, has not changed.
Ecological Risk Assessment
There have not been any changes to the toxicity factors or other contaminant characteristics that affect
the protectiveness of the remedy for ecological receptors at the Site.
Are there newly identified contaminants or contaminant sources leading to a potential/actual pathway
not previously addressed by the remedy?
Per- and polyfluoroalkyl substances (PFAS) are a group of emerging contaminants, consisting of more
than 5,000 man-made fluorinated organic chemicals known for their water, oil, and stain repellency.
PFAS chemistry was discovered in the late 1930s and widespread use began in the 1950s. PFAS have
historically been used in numerous industrial processes, including electroplating (Interstate Technology
Regulatory Council, 2020).
Question C: Has any other information come to light that could call into question the
protectiveness of the remedy?
Former disposal of industrial wastes at the Red Oak Landfill justifies a detailed evaluation of current and
past site activities being conducted to determine whether PFAS may have been disposed of at the Site.
This evaluation should determine whether historical site operations may have resulted in the release of
PFAS to the environment.
To the best of our knowledge, during the FYR period no impacts from climate change have occurred that
affect the protectiveness of the remedy. Potentially, future increases in precipitation could elevate
groundwater levels to contact impacted vadose zone soils or affect transport of impacted groundwater.
Future flooding could also impact the integrity of the cap.
No other information has come to light during this FYR period that would call into question the
protectiveness of the remedy.

Red Oak Landfill Five-Year Review Site Inspection
Red Oak Landfill Superfund Site
Red Oak, Iowa
EPA ID No. # IAD980632509
PROJECT CUSTOMER
David Wennerstrom, Remedial Project Manager, SEMD
PURPOSE AND GOALS OF THE
FIELD ACTIVITY
Inspection of site as required by CERCLA for the Five-Year Review to determine
protectiveness of the implemented remedy
START AND END DATE(s) (when
the field activity occurred)
October 26, 2021
FIELD TEAM MEMBERS (names
and organizational affiliations of all
people who participated in the field
activity including those from
organizations outside of LSASD)
David Wennerstrom, EPA; Randy Brown, EPA; Matt Culp, IDNR; Brad Wright, City
Administrator, representatives from Magna and Atlas (responsible party and consultant).
On October 26, 2021,1 accompanied Remedial Project Manager David Wennerstrom to the
Red Oak Landfill Superfund Site ("Site") in support of the Five-Year Review (FYR) Site
Inspection. Observations and comments are included below. The Site photographs are
attached.
1) General Security and Site Conditions. Gates were locked at the Site and secure. The Site
had been mowed recently and appeared to be in a well-maintained condition.
LOCATIONAL INFORMATION,
ACTIONS PERFORMED, AND THE
RESULTS OF THOSE ACTIONS
(include references to logbooks, sample
sheets or logs, forms, and checklists as
appropriate. Discuss where photos,
videos, and collected measurements
and observations may be found, as well
as where data from analyzed samples
will be maintained. Analysis of data and
information is not expected. Discuss
whether planned goals were achieved
and if not, why not.)
2) Landfill Cap/Cover. The cap appeared to be in very good condition with no erosional rills,
scours or exposed waste visible. There was no standing water observed on the cap even
though a four-inch rain event had occurred within 72 hours of the inspection.
3) Landfill Surface Drainage. Although a four-inch rain event had occurred less than 72 hours
prior to the inspection, the surface drains were dry with no visible standing water, no brush or
debris clogging drain outlets or inlets, or significant staining. No significant erosional rills or
other features were observed.
4) Monitoring Wells. Well covers and protective caps were intact on all monitoring wells and all
monitoring wells had functional locks. Concrete aprons were cracked on Monitoring Wells
GW-03 and GW-04 (see photographs).
5) Bank Stability. No recent slumping was observed on the slope of the landfill adjacent to the
East Nishnabotna River. The previous slump line appeared to be stabile with native grasses
and trees growing into the slump line. Native trees are becoming established along the entire
slope in addition to the trees planted as part of the bank stabilization. The native grass cover
appeared to be reestablishing well. No erosional boils, exposed waste, or bank scours were
observed along the bank frontage of the East Nishnabotna River.
6) Findings/Issues/Concerns. The protective concrete aprons foster proper surface drainage
away from the well casings. It is recommended that the protective concrete aprons be
repaired for the monitoring wells indicated above in Comment 6. No other significant
concerns with Site conditions were observed. See accompanying photographs.

RE: Monitoring, Operation and Maintenance Report (2020)
Red Oak Landfill Superfund Site, Red Oak, Iowa
Dear Mr. Wennerstrom:
On behalf of Magna Seating of America, Inc. (Magna), and the City of Red Oak, please find
enclosed the 2020 Annual Monitoring, Operation and Maintenance Report for the Red Oak
Landfill Superfund site as required under the Consent Decree entered November 27, 1996. This
report has been prepared by ATC Group Services LLC of Omaha using monitoring data and
riverbank slope observations collected on behalf of Magna in 2020, and with reports supplied by
the City of Red Oak on Operations and Maintenance activities.
This MOMP Report covers the twentieth year of monitoring and inspection data collected at this
site under the Consent Decree. During the 2020 sampling event, water collected from
seep/spring, surface water and groundwater was analyzed for Target Compound List (TCL)
VOCs, total TCL inorganics (Short List) and dissolved TCL inorganics (Short List).
The 2020 program also included the Spring Landfill Cap and Riverbank Slope Reconnaissance,
Gauging of Inclinometer INC-1, Annual Landfill Cap Maintenance, testing and inspection
activities. The 2020 sampling results do not indicate significant changes from previous trends
observed for the analytes sampled.
With regard to the riverbank slope, two (2) separate inspections of the slope were made in 2020.
While some movement of soil was noted, no new areas of significant slope slumping or
movement were identified and historic areas of slumping showed evidence of re-establishment of
-------
-2-
vegetation as well as tree growth. In addition, measurements collected from the inclinometer at
the Site indicates there is no deep movement of the slope.
If you should have any questions regarding the report on groundwater/surf ace water data
acquisition, analytical portions of the monitoring event, or the groundwater user survey, please
contact Avin Duggal at 905-726-7473. Questions regarding the City Operations and
Maintenance activities should be directed to Mr. Brad Wright, the Red Oak City Administrator.
Administrative issues should be directed to either Avin Duggal or to Mr. Wright.

1.0 INTRODUCTION
1.1 Purpose
This Report is prepared by ATC in accordance with the requirements of the Monitoring, Operations and
Maintenance Plan (MOMP), February 2000, prepared for the Red Oak Landfill Superfund Site (Site)
approved by the United States Environmental Protection Agency (EPA). The MOMP was required by the
EPA per the Consent Decree entered on November 27, 1996, by the U.S. District Court for the Southern
District of Iowa, Western Division - Red Oak Landfill Superfund Site, as set forth in Appendix A to the
Consent Decree: Scope of Work (SOW) For The Remedial Design, Remedial Action, And Operation And
Maintenance At The Red Oak Landfill, Red Oak, Iowa. Under this Decree, The City of Red Oak (City)
and Magna Seating of America, Inc. (Magna) (formerly known as Intier Seating of America, Inc. and as
ultimate successor by merger to Douglas & Lomason Company) are responsible for monitoring,
maintenance and inspection of the various aspects of the selected Site remedy including the landfill cap,
drainage features, Site security measures, monitoring wells, monitoring well protection/identification
devices, and the vegetation and stability of the riverbank slope. The River Bank Slope stabilization was
approved November 19, 2002 and the associated monitoring and maintenance activities were subsequently
incorporated into the MOMP responsibilities of the City and Magna.
1.2 Site Location
The Site is located approximately 1.5 miles northwest of the City of Red Oak, Montgomery County, Iowa
(see attached Figure 1). The Site encompasses approximately 40 acres and is located on the west bank of
the East Nishnabotna River on the east side of "G Avenue (formerly Parkwest Road) in Section 17,
Township 72 N, Range 38W. The Site is bounded by farmland on the north and south, "G" Avenue and a
quarry pond/private lake to the west and the East Nishnabotna River to the east. Farmland and trees lie to
the east of the river. The attached Figure 2 presents a Site Map.
1.3 2020 Site Events and Issues
The following activities were completed at the Site in 2020 in compliance with the MOMP:
• Spring Landfill Cap and Riverbank Slope Reconnaissance
• Gauging of Inclinometer INC-1
• Annual Landfill Cap Maintenance, Testing and Inspection Activities
• Groundwater, Seep/Spring, and Surface Water Sampling and Analysis
• Fall Landfill Cap and Riverbank Slope Reconnaissance
• Annual Groundwater Use Survey
A detailed explanation of each of these activities and the associated findings is provided in later sections of
this report.
In a correspondence to U.S. EPA Region 7, dated January 10, 2014, ATC proposed the removal of
Ammonia Nitrogen, Chloride, Chemical Oxygen Demand (COD) and Total Organic Halogens (TOX) from
the Site monitoring program. ATC also proposed a reduction in monitoring well sampling frequency from
annually to biennially, every other year, unless analytical results or site observations suggest continued
annual monitoring is warranted. These modifications, with several provisions, were approved by the EPA
Project Manager of record, Ms. Shelley Brodie, in e-mail correspondence dated March 29, 2014 prior to
her retirement. The primary provision affecting this submittal is that the Annual Monitoring Operations

3.0 OPERATION AND MAINTENANCE ACTIVITIES
The City of Red Oak (the "City") performed the 18th annual (eighteenth since November 7, 2002) Landfill
Cap inspection on September 3, 2020. Inspection and maintenance activities undertaken are as more
specifically described in the following sections. Generally, inspection disclosed the condition ofthe Landfill
Cap, fence and security measures, monitoring wells, Energy Dissipation Structures ("EDS") and Drainage
System Components ("DSC") to be in good condition and fulfilling the operations for which they were
designed.
3.1 Landfill Cap and Stabilized Riverbank Slope Inspection
3.1.1 Landfill Cap Inspection
Inspection of the Landfill Cap was performed by Chris Day, Red Oak Wastewater Superintendent, on
September 3, 2020. Inspection began at 1:00 P.M. and concluded at 3:00 P.M. The weather was noted as
partly cloudy with temperature in the mid-60s. No defects of the final cover and side slopes were noted. No
cracking, settlement, burrows or other animal activities were noted. No slumping or sliding of the Landfill
Cap was noted. No unwanted plant species were noted. No low spots or ponding were noted. No damaged
or improperly compacted areas were noted. No irregularities or protrusions were noted. The EDS and DSC
were noted be to be in good condition and serving the purposes for which they were constructed. The
Landfill Cap perimeter fencing and warning signs were inspected and noted to be in good condition and
serving the purposes for which they were erected.
3.1.2 Stabilized Riverbank Slope Inspection
Inspection ofthe Stabilized Riverbank Slope was performed on January 8, 2020. Inspection was performed
by Chris Day, Red Oak Wastewater Treatment Plant Superintendent. The inspection was conducted to look
for distressed, disturbed or unwanted vegetation, and for defective conditions such as eroded areas, soil
slumping, tension cracks and isolated slump blocks. From the observation of Chris Day, there was no
serious deterioration in the condition of the Stabilized Riverbank Slope from the 2019 inspection. Eroded
areas were noted to exist. Isolated slump blocks were noted to exist in areas between Markers Ml and M3.
No unwanted vegetation was noted to be present. The weather on January 8 was noted to be in the mid-40s
and sunny.
A second inspection of the Stabilized Riverbank Slope was conducted June 12, 2020, by Chris Day, Red
Oak Wastewater Superintendent. Inspection began that day at 9:00 A.M. and ended at 10:30 A.M.
Inspection disclosed no serious changes from the previous inspection. Noted were one or two small eroded
areas, some unwanted vegetation inaccessible for removal due to the slope angle. Vegetation does not
appear to be causing any damage. Trees appear healthy. Weather was partly cloudy with temperature in the
low 70s.
3.2 Landfill Cap and Stabilized Riverbank Slope Maintenance
3.2.1 Landfill Cap and Surrounding Area Mowing

4.0 MONITORING ACTIVITIES
The 2020 groundwater monitoring activities were conducted by Mr. Eric Brown, Mr. Eric
Mueggenberg, and Mr. Doug Sayer of ATC's Des Moines, Iowa office. Purging was conducted on July
24, 2020 and groundwater sampling activities were conducted on July 27, 2020. ATC returned to the
site on October 19th and collected stabilization data. GW01 and GW03 through GW05 were purged
and sampled during onsite activities. Monitoring well GW02R, installed in May 2011 as a replacement
for monitoring well GW02, which was destroyed by slope movement in its vicinity in mid-June of
2008, continued to be dry and was not sampled. Mr. Brown returned to the Site on September 23, 2020
to collect total cyanide samples from the wells.
Groundwater monitoring activities were conducted in 2020 per the modifications made to the Site
Monitoring Program approved by the EPA on March 29, 2014. See Section 1.3 and Appendix H,
Other Supporting Documents. A brief history of modifications to the original project Field Sampling
Plan and documentation of approval of those modifications is included in Appendix H. The last
groundwater monitoring activities were conducted in 2018.
Surface water sampling of the East Nishnabotna River, upstream and downstream of the landfill, was
conducted by Mr. Eric Brown of ATC's Des Moines, Iowa office. Sampling activities were conducted
on July 27, 2020 for VOCs and inorganics and on September 23, 2020 for total cyanide. Sampling
locations are identified on the attached Figure 2. Observations and sampling details were recorded in
the Site Monitoring Log Book dedicated to this Site.
Seep/spring sample SS01 was collected during the July 27, 2020 and September 23, 2020 sampling
events.
During the 2020 monitoring event, water samples collected from the monitoring wells, seep/spring, and
the East Nishnabotna River were analyzed by the laboratory for the presence and concentration of the
following compounds, elements and indicator parameters:
• Target Compound List - Volatile Organic Compounds (TCL-VOCs);
• Target Analyte List - Inorganics (Total and Dissolved - Target Analyte Full List)
EPA's approval of modifications to the Site monitoring program in March of 2014 removed the analysis
of Ammonia Nitrogen, Chloride, Chemical Oxygen Demand (COD) and Total Organic Halogens
(TOX) from the analyte list. The 2014 modifications also set a sampling schedule for the Target
Analyte Full and Short Lists. A complete listing of the compounds and elements included in the TCL-
VOCs and Target Analyte List is included in Appendix B. A table comparing the elements and
parameters included in the Target Analyte Full List and the Target Analyte Short List is provided in
Appendix H.
Other monitoring activities specified in the MOMP, including monitoring the condition of the
Riverbank Slope, seep/spring sampling and groundwater use in the area are addressed in subsequent
sections of this report.
The following sections summarize the various components of required Site monitoring which include:
• Groundwater Sampling (Section 4.1)
• Surface Water Sampling (Section 4.2)
• Riverbank Slope Inspection (Section 4.3)
• Landfill Seep/Spring Sampling (Section 4.4)

• Groundwater Use Review (Section 4.5)
Annual gauging of the site inclinometer, installed in October of 2009, has been voluntarily initiated by
Magna and these results are discussed in Section 4.6.
Section 5.0 (Recommendations) contains ATC's recommendations that are deemed appropriate for the site
based on the conditions outlined in this report.
Summaries of the analytical program results are included in Tables 1A-F, 2A-C, & 3 in Appendix I which
address, groundwater monitoring results, surface water results, and seep/spring sample results respectively.
Brief narrative summaries of the analytical results for groundwater, surface water, and seep/spring sampling
are provided in Section 4.1.4, Section 4.2.4 and Section 4.4.4, respectively.
4.1 Groundwater Sampling
This section summarizes the various groundwater data collected during the purging and sampling of
locations GW01 and GW03 through GW05 on July 27, 2020, September 23, 2020, and October 19, 2020.
It also summarizes the procedures used in collection of the groundwater samples, any problems
encountered, and the results of the field and laboratory testing programs.
4.1.1 General Information
Groundwater sampling activities were conducted for calendar year 2020 in accordance with the biennial
sampling schedule approved in 2014. ATC investigated the Target Analyte Full List. The next sampling
event will investigate the Target Analyte Short List in 2022. Purging was performed on July 24, 2020 and
groundwater sampling was conducted on July 27, 2020 and September 23, 2020 (total cyanide only).
Purging was conducted again on October 19th to obtain stabilization data. Duplicate sample GW06 (a
duplicate of sample GW05) was collected during the July 27, 2020 sampling event. Tables 1A through IF
(Appendix I) summarize current and historical groundwater data including the dates the wells were
sampled, depth to groundwater, groundwater elevation, field parameter data, and all analytical data. The
tables have been organized to enable comparison of the analytical results for the various monitoring events
at each sample location.
4.1.2 Procedures
Groundwater sampling at the Site was conducted in accordance with the requirements and procedures of
Section 7.0 Monitoring Activities of the Field Sampling Plan portion of the Red Oak Landfill Superfimd
Site Monitoring, Operation and Maintenance Plan, dated February 2000. The final plan was adopted by
the EPA in their approval letter of March 2, 2000. These procedures are also in accordance with EPA
Region 7 Standard Operating Procedures, which are incorporated by reference in Appendix C. Sampling
of the Site monitoring wells was conducted in accordance with the following procedures:
Site Preparation
The protective casing lock and cap was removed. Upon opening the well casing cap, the top of the well
casing, and breathing zone above the well, was screened for the presence of organic vapors with a MiniRAE
3000 photoionization analyzer equipped with a 10.6 eV lamp. These results were recorded in the Site
Monitoring Log Book (Appendix D).
The depth to groundwater and total well depth were measured with an electronic water level indicator and
these results recorded in the Site Monitoring Log Book (Appendix D). Based upon these readings, and the
diameter of the well, the volume of the water column was calculated and the volume to be purged (3 to 5
Monitoring, Operation, and Maintenance Report - 2020

n
well volumes) estimated. This information was also entered on the Site Monitoring Log Book (Appendix
D)
Purging
Each well was purged with a dedicated, bottom-loading, disposable, polyethylene bailer and 1/8-inch
diameter nylon rope. Samples for pH, temperature, and conductivity testing were collected directly from
the bailer, after each well volume had been purged from the well at a minimum. The results of these tests
are recorded in the Site Monitoring Log Book (Appendix D) and in Table 4 (Appendix I).
Each well was purged until:
• Approximately five (5) well volumes of water had been removed, or;
• The well was purged nearly dry (less than 12 inches of water in the bailer).
Temperature, pH, and conductivity stabilization data was not recorded during purging activities. Further
discussion is contained in Section 4.1.3,
Sampling
Dedicated, disposable, bottom-loading polyethylene bailers and 1/8-inch diameter nylon rope were utilized
to sample the site monitoring wells. Prior to sample collection, the bailer was rinsed with approximately
three (3) bailer volumes of water from the well when sufficient water was available. Samples were
generally collected in the following order:
• Target Analyte List - Inorganics (Dissolved);
• Target Analyte List - Inorganics (Total);
• Target Compound List - Volatile Organic Compounds (TCL-VOCs)
Specific information regarding sampling sequence at each sample location is provided in the Site
Monitoring Log Book.
A one (1) liter bailer (Voss Technologies) was selected for sampling due to the ability to attach an in-line,
disposable 0.45 micron filter cartridge directly to the bailer, and collect the filtered sample directly from
the bailer/filter assembly.
The samples for VOC analysis were carefully poured from the bailer into 40 ml VOA vials using care not
to agitate or aerate the sample. The vials were filled until a positive meniscus was formed at the top of the
vial. The cap was then placed on the vial, tightened, and the vial inverted to check for any entrapped air
bubbles in the sample. If bubbles were identified, the vial was discarded and a new vial was filled.
The remaining samples were collected directly from the bailer using care not to overfill the sample container
and dilute any preservatives.
Sample Packaging
Prior to sample acquisition, the sample containers were labeled. Following sample acquisition, the filled
sample containers were dried and placed in coolers with ice. VOC sample vials were placed in preformed
foam containers prior to being placed in the cooler.
Upon completion of the sampling on July 27, 2020 and September 23, 2020, the samples were taken back
to ATC's Des Moines, Iowa office, then the samples were refrigerated at 4±2 degrees Celsius. The samples
were repacked with ice in coolers along with the completed Chain-of-Custody. A Custody Seal was affixed

n
to the coolers and they were picked up by a Eurofins TestAmerica courier the following morning for
delivery to Eurofins TcstAmcrica's laboratory located at 3019 Venture Way, Cedar Falls, Iowa. A copy of
the Chain-of-Custody is included with the laboratory analytical report in Appendix E.
Equipment Decontamination
All purging and sampling equipment utilized during the sampling event was disposable and included:
• #18 Mason nylon rope
• polyethylene bailers for purging and sampling
• 0.45 micron filter cartridges
These materials and other related solid waste (used PPE, paper towels, etc.) were disposed of as
"Unclassified Investigation-Derived Waste."
The only equipment requiring decontamination was the water level indicator utilized to determine
groundwater and well depth. Following each use, the instrument probe and cable were washed in an
Alconox/potable water solution, rinsed in potable water, and wiped with a paper towel soaked with
deionized water and allowed to air dry.
Field equipment and probes used to measure temperature, conductivity, and pH that contacted the
potentially contaminated groundwater were rinsed with deionized water. This equipment had no contact
with any of the sampled media. All other equipment, including buckets, was decontaminated with an
Alconox/potable water solution wash and potable water rinse between sample locations and prior to leaving
the Site. As an additional precaution to minimize the potential for cross contamination of samples, the Site
sampling team changed nitrile gloves, at a minimum, between sample locations.
Investigation Derived Waste Management
Based upon the results of previous site sampling, investigation derived solid waste was disposed of as
common non-hazardous solid waste off site. All purge water and decontamination fluids were collected in
5-gallon plastic buckets, and disposed of near the well site through infiltration into the ground surface.
Field Sampling OA OC
Instruments utilized during the sampling event included a MiniRAE 3000 photoionization analyzer
equipped with a 10.6 eV lamp and an YSI pH/Con PRO 1030 Series pH, conductivity and temperature
meter. The calibration of the equipment was performed by ATC.
Field Blanks
A field blank, designated Field Blank (on chain-of-custody), was collected on July 27, 2020. The sample
was collected at the Site by filling laboratory provided containers with appropriate preservatives for each
of the monitored parameters with laboratory provided water in accordance with the previously noted
sampling procedures.
The field blank was analyzed for the Target Compound List - Volatile Organic Compounds (TCL-VOCs).
VOCs were not detected above the laboratory reporting limit (RL) in the field blank sample.
Monitoring, Operation, and Maintenance Report - 2020

ATC
-AN ATLAS COMPANY—
Trip Blanks
Coolers, provided by Eurofins TestAmerica Laboratories, for the 2020 sampling event contained a
laboratory prepared trip blank. The blank accompanied the coolers containing sample containers to be
analyzed for chemicals of concern.
The trip blank was analyzed for the Target Compound List - Volatile Organic Compounds (TCL-VOCs).
All of the analyzed parameters in the trip blank were reported at concentrations less than the laboratory RL.
Duplicate Samples
Duplicate samples for all analyzed parameters, except total Cyanide, were collected from monitoring well
GW05 (labeled GW06).
Two VOCs (1,2-dichloroethene (total), and Vinyl Chloride) were detected above the laboratory RL in
monitoring well GW05 and its duplicate. The VOC results were within 5% and 1% of each other,
respectively. Duplicate values for the total and dissolved metals analyses for GW05/GW06 were within
14% of the reported maximum for each of the metals. Duplicate values compared favorably and do not
suggest serious field sampling or laboratory inconsistencies.
There were no significant data qualifiers reported by the laboratory.
The reported RL for Arsenic - groundwater was greater than the identified action level. It should be noted
that Arsenic has a very low action level (0.02 (ig/L) which is routinely lower than the laboratory reporting
or method detection limits for the analytical methods utilized. With this exception, the reported values have
sufficient accuracy and are suitable for their intended purpose.
4.1.3 Sampling Problems or Variances from MOMP
Variances
Two (2) variances from the MOMP sampling protocol were requested previously from Mr. Robert L.
Stewart of EPA Region 7. These variances involved the substitution of disposable polyethylene bailers for
the approved disposable Teflon bailers and the use of the in-line filter for field filtration instead of
disposable field filter kits. The ATC Associates" (predecessor to ATC Group Services) letter requesting
the variance, dated May 14, 2001, and the EPA approval letter authorizing the substitution, dated May 17,
2001, are included in Appendix H.
At that time, ATC Associates also discussed the need for the Teflon-coated stainless steel wire leader
between the bailer and the twine during a telephone conversation with Mr. Stewart. The previously noted
EPA approval letter also authorized omission of the Teflon leader wire.
The following variances from the MOMP were made in the field:
• Temperature, pH, and conductivity was not collected from groundwater wells during purging and
sampling. The data was collected during the fall slope observations on October 19, 2020.
• During the July 27, 2020 sampling event, containers for total cyanide analysis were not included
with the samples. ATC obtained containers for total cyanide analysis from Eurofins Test America
and returned to the site on September 23,2020 to resample the wells, surface water, and seep/spring.
The wells were not purged prior to total Cyanide sampling.
These modifications should not have any effect on sample integrity or analytical results. Care will to be
exercised in the future to assure that stabilization readings are collected during purging activities.

n
Additionally, the contents of laboratory provided coolers will be cataloged prior to conducting field
operations.
Sampling Problems
Sampling problems or potential well issues were present at two (2) of the five (5) well locations for the
2020 sampling event.
As noted previously, monitoring well GW02 has been destroyed by slope movement as of 2008.
Replacement monitoring well GW02R, installed in May 2011 above the former well location in the cap
berm, has not contained sufficient water to sample. This continued to be the case when the well was gauged
in July and September of 2020.
Problems associated with monitoring well GW04 are related to slow recharge of the well from the
monitored aquifer. The problem encountered at this location has been consistent since monitoring was
initiated in 2001.
Identified issues, or their absence, are summarized as follows:
• GW01 - No problems with stabilization or sampling were encountered during the 2020 monitoring
event.
• GW02 - Well destroyed due to Riverbank Slope movement in 2008.
• GW02R - GW02 replacement well. To date, this well has not contained sufficient water to sample.
• GW03 - No problems encountered at this well location.
• GW04 - Monitoring well GW04 was historically sampled in a manner that the well was purged on
one date and sampled approximately one (1) to two (2) weeks later, allowing the well to recharge
sufficiently to collect the required samples. During the 2020 sampling event ATC sampled the
well, and all other wells, three (3) days after purging. This sampling approach had been approved
previously by both Ms. Janet Haynes of Magna International and Mr. Robert Stewart of EPA
Region 7 and is followed consistently at this well location.
• GW05 -There were no sampling difficulties associated with this monitoring location.
During the July 27, 2020 sampling event, containers for total cyanide analysis were not provided by the
lab. ATC obtained containers for total cyanide analysis from Eurofins Test America and returned to the
site on September 23, 2020 to resample the wells, surface water, and seep/spring. The wells were not
purged prior to total Cyanide sampling.
There were no other sampling, transportation or container damage issues during this monitoring event.
4.1.4 Analytical Summary
Two (2) primary pathways of exposure to contaminants of concern have been identified as being associated
with the Red Oak Landfill.
1. Groundwater exposure; and
2. Potential impacts to surface water quality.
Prior to submittal of the 2011 Monitoring, Operations and Maintenance report, analytical results had been
compared only to drinking water quality standards. The 2011 Report also included a discussion of

Subsequent to submittal of the 2011 Monitoring, Operation and Maintenance Report, the Third Five-Year
Review Report for the Red Oak Landfill Siiperfiind Site, Montgomery County, Iowa was prepared by the U.
S. Army Corps of Engineers (USACOE) on behalf of the U.S. Environmental Protection Agency Region
7. Tables 2 and 3 of the Third Five-Year Review Report summarize Action Levels for Contaminants of
Concern which are applicable to the Site for groundwater and surface water impacts. These action levels
are based upon a review of both state and federal regulations. Table 2 addresses Groundwater Action Levels
and Table 3 addresses Surface Water Action Levels. These tables are included in Appendix F and their
sources are summarized in the following paragraph.
The Record of Decision (ROD) for the Site, dated March 31, 1993, references applicable State regulations
for defining Action Levels for groundwater. 567 Iowa Administrative Code (IAC) 133 requires that certain
actions be taken when "action levels" are exceeded in groundwater. Section 6.4 of the referenced Five-
Year Review Report indicates the referenced action levels are selected from a hierarchy of values specified
in 567 IAC 133.2. When available, the hierarchy, in order of preference, is as follows: the lifetime Health
Advisory Level (HAL); the Negligible Risk Level (NRL) which is the concentration associated with a 10 6
cancer risk; federal primary Maximum Contaminant Levels (MCLs) if selected under state regulation; and
finally, a value based on expert evaluation of appropriate action levels based upon risk, such as the Regional
Screening Levels (RSL) table (EPA, 2011).
As noted, surface water classifications and water quality criteria were first addressed in the 2011 Monitoring
Operations and Maintenance Report and were obtained from the Iowa Department of Natural Resources
(IDNR) website. Chapter 61 - Water Quality Standards of the Iowa Administrative Code and Surface
Water Classification, dated December 22, 2010, and other IDNR resources indicate that the following
designated use segments are defined for the East Nishnabotna River at Red Oak: Class A1 - Primary
Contact Recreational Use; Class B(WW-l) - Warm Water Type 1; and Class HH - Human Health.
Class A1 waters are defined as those waters in which recreational or other uses may result in prolonged and
direct contact with the water, involving considerable risk of ingesting water in quantities sufficient to pose
a health hazard. Such activities would include, but not be limited to, swimming, diving, water skiing, and
water contact recreational canoeing.
Class B (WW-1) waters are those in which temperature, flow and other habitat characteristics are suitable
to maintain warm water game fish populations along with a resident aquatic community that includes a
variety of native nongame fish and invertebrate species. These waters generally include border rivers, large
interior rivers, and the lower segments of medium-size tributary streams.
Waters having the HH classification are waters in which fish are routinely harvested for human
consumption or waters both designated as a drinking water supply and in which fish are routinely harvested
for human consumption.
In addition to the preceding, the USACOE Five-Year Review identified Federal Ambient Water Quality
Criteria (AWQC) that are applicable to surface waters adjoining the Site. The AWQC addresses three (3)
scenarios, the first being a situation in which an individual may use the surface water as a drinking water
source while also consuming aquatic organisms taken from the surface water body. The second is
applicable to an individual only consuming aquatic organisms taken from the surface water body. The final
scenario addresses the ecological effects of the chemicals of concern. The associated chronic Criterion
Continuous Concentration (CCC) represents the highest in-stream concentration to which aquatic
organisms can be exposed indefinitely without the occurrence of unacceptable effects.

As noted, in the 2011 MOMP Report, results from the site monitoring wells were compared against the
groundwater and surface water quality standards. This was not continued in the 2012 and subsequent
Reports since monitoring well data cannot be compared directly with the surface water standards due to
contaminant degradation and dilution of the chemicals of concern which will occur prior to and upon
reaching the river. Thus, for reference purposes, the monitoring well data is compared to the applicable
groundwater quality action level listed in the table included in Appendix F and are not compared to surface
water action levels in the following section.
Volatile Organic Compounds
Identified groundwater action levels for the monitored VOCs, and identified as contaminants of concern,
are summarized in Appendix F. These action levels are compared with the analytical results in the tables
included in Appendix I.
Throughout the monitored period (2001-2020), evidence of volatile organic compounds has generally only
been reported in monitoring well GW05. Since monitoring was initiated in 2001, low concentrations of
Acetone (52 |ig/L). 1,2-dichloroethane (1.12 (ig/L), 1,2-dichloroethene (total) (1.68 to 3.97 (ig/L), 4-
Methyl-2-Pentanone (concentrations 104 to 369 |ig/L). Toluene (5.2 to 108 |ig/L). Vinyl Chloride (2.1 to
2.75 (ig/L), and Xylenes (6 |ig/L) have historically been reported in the well. Exceptions to the preceding
statement are GW02 where cis- 1,2-dichloroethene was reported at a concentration of 6 |ig/L on one
occasion, and GW04 where Benzene was detected twice, at concentrations of 1.0 and 0.924 |ig/L and 1,2-
dichloroethane was detected once at 1.12 (ig/L. With these exceptions, all of the remaining sample locations
and parameters included in the VOC Target Compound List have historically been reported at
concentrations less than the laboratory MDL or RL.
The 2020 sampling event identified concentrations of 1,2-dichloroethene (total) and Vinyl Chloride in
GW05 at 1.68 |ig/L and 2.17 (ig/L, respectively. Dichloroethene (total) and cis- 1,2-dichloroethene have
identified action limits of 70 |ig/L. There is no identified action limit for Vinyl Chloride. None of the
reported VOC concentrations reported for the 2020 sampling event exceeded the identified groundwater
action levels.
Metals and General Chemistry Parameters
Identified groundwater action levels for the monitored metals and general chemistry parameters are
summarized in Appendix F. These action levels are compared with the analytical results in the tables
included in Appendix I.
Sampling program modifications approved in March of 2014 changed the Full Target Analyte List
monitoring schedule to a four (4) to six (6) year schedule to incorporate a set of Full Target Analyte List
data in the Site Five-Year Review process. The Full Target Analyte List of parameters, as presented in
Appendix H, adds Antimony, Beryllium, Calcium, Copper, Lead, Magnesium, Mercury, Potassium, Silver,
Thallium, Vanadium, Cyanide and Phenols to the Short List. According to the 2014 sampling schedule,
the Full List was investigated in 2020. In accordance with the 2014 schedule, the Full Target Analyte List
will be sampled next in 2026.
The analytical results for 2020 are summarized by the following paragraphs. The discussion also compares
the results to the identified groundwater quality standards. Graphical results of these analyses are presented
in Appendix I.
Aluminum - The identified groundwater action level for Aluminum is 16,000 (ig/L. Total Aluminum was
not detected above the RL of 50 (ig/L in any of the monitoring wells during the 2020 sampling activities.

As such, there were no total Aluminum concentrations reported in the monitoring wells that exceeded the
identified groundwater action level. The 2020 results are consistent with previous results and continue to
indicate a decreasing concentration trend from values reported between 2005 and 2009, when Total
Aluminum concentrations varied widely with significant spikes being followed by periods of reduced
values. Dissolved Aluminum in each of the monitored wells was also reported at a concentration of <50
(ig/L, which is consistent with previously reported results.
Arsenic - The identified groundwater action level for Arsenic is 0.02 (ig/L. Concentrations of total Arsenic
ranged from <2.0 to 13.6 (ig/L. Total Arsenic values reported in GW01 and GW04 were below the detection
limit of 2.0 (ig/L. All of the reported total Arsenic values potentially exceed the groundwater action levels.
The total Arsenic concentrations reported in GW01 and GW04 continue to indicate a trend of low
concentrations. Total Arsenic values reported in GW03 and GW05 are lower than those reported in 2016
and 2018, however they remain within the range of values previously reported for those locations. Total
Arsenic has decreased in concentration over the last four years at GW03 and GW05; however, no overall
contaminant concentration trends are apparent for the wells.
Values of dissolved Arsenic were reported at concentrations ranging from <2.0 (ig/L (GW01 and GW04)
to 33.5 (ig/L (GW03). All of the reported dissolved Arsenic concentrations are potentially greater than the
groundwater action level. The similarity between total and dissolved Arsenic concentrations of GW05
indicates that the majority of the Arsenic is present in the dissolved phase. The dissolved Arsenic
concentration of GW03 is over double the concentration of total Arsenic, potentially further indicating that
the majority of arsenic is present in the dissolved phase or laboratory error.
Barium - The identified groundwater action level for Barium is 2,000 (ig/L. The total Barium
concentrations reported in the monitoring wells for 2020 range from 46.6 to 635 (ig/L and dissolved Barium
concentrations range from 48.2 to 633 (ig/L. None of the total or dissolved Barium results exceeded the
groundwater action level. The reported values of total and dissolved Barium decreased from those reported
in 2018, with the exception of GW03, and are relatively consistent with previously reported values. There
are no readily apparent dissolved Barium trends in the monitoring wells. The similarity between total and
dissolved values in the wells indicates that Barium is primarily present in the dissolved phase.
Cadmium - The identified groundwater action level for Cadmium is 5 (ig/L. For 2020, both total and
dissolved Cadmium was not detected above the laboratory RL of 0.1 (ig/L in the monitoring wells. These
values do not exceed the groundwater action level. All of the reported total and dissolved Cadmium
concentrations are consistent with those reported previously.
Chromium - The identified groundwater action level for Chromium is 100 (ig/L. For 2020, all of the total
and dissolved Chromium concentrations in the monitoring wells were reported as <5.0 (ig/L. All the
reported total and dissolved Chromium concentrations are below groundwater action levels.
Cobalt - The identified groundwater action level for Cobalt is 4.7 (ig/L. 2020 concentrations of total and
dissolved Cobalt in GW01, GW03 and GW04 were all below <0.5 (ig/L. In GW05, the total Cobalt
concentration was 8.00 (ig/L and dissolved Cobalt was 8.24 (ig/L. Only the total and dissolved Cobalt
concentrations reported at GW05 for 2020 are greater than the groundwater action level. Historically, data
from GW05 has consistently been greater than the action level. The reported values are within the range
of previously reported values. Concentrations in GW05 have increased since 2018 but continue to indicate
an overall decreasing trend since 2012. The current IDNR Statewide Standard for a protected groundwater
source is 2.8 (ig/L of Cobalt, and is lower than the identified action level in Table 2. The 2020
concentrations do not exceed the IDNR Statewide Standard with the exception of GW05. The EPA RSL

that is the basis of the identified action level has been updated to 6.0 (ig/L since the establishment of the
Groundwater Action Levels. The concentrations identified in GW05 are still greater than the updated RSL.
Iron - The identified groundwater action level for Iron is 11,000 (ig/L. For the 2020 monitoring event,
total Iron concentrations ranged from <100 to 19,100 (ig/L. Total Iron concentrations in GW03 and GW05
were reported at 19,100 and 15,400 (ig/L, respectively. Dissolved Iron was reported at 19,400 (ig/L in
GW03 and 16,700 (ig/L in GW05. Only the total and dissolved Iron concentrations reported in GW03 and
GW05 were greater than the groundwater action level. All of the total Iron values reported in the remaining
monitoring wells for the current monitoring event are consistent with the ranges reported at those locations
historically. There are no readily discernible trends in the total Iron data with the exceptions of GW01 and
GW04, which appear to be relatively stable. The similarity between the total and dissolved concentrations
indicates that the majority of Iron is present in the dissolved phase. The RSL that forms the basis of the
iron action level has been updated to 14,000 (ig/L since the establishment of the Groundwater Action
Levels. The Iron concentrations in GW03 and GW05 are still greater than the updated RSL.
Manganese - The identified action level for Manganese is 300 (ig/L for groundwater. The concentrations
of total Manganese reported in 2020 range from <10 (ig/L (GW01 & GW04) to 6,150 (ig/L (GW05). Only
the total and dissolved Manganese concentrations reported in GW03 and GW05 were greater than the
groundwater action level. The reported value at each well location was within the range of previously
reported values. Contaminant trends in GW01 and GW04 are generally flat. There are no discernible trends
in either the GW03 or GW05 data. Concentrations of dissolved Manganese in the monitored wells for 2020
range from <10 (GW01 & GW 04) to 5,790 (GW05) (ig/L and are consistent with the range of results
reported previously at those locations. Comparison of total and dissolved phase concentrations for 2020
suggests that nearly all of the Manganese is in the dissolved phase.
Nickel - The groundwater action level identified for Nickel is 100 (ig/L. For the 2020 monitoring event,
reported concentrations of total Nickel range from <5.0 to 6.26 (ig/L and dissolved Nickel concentrations
ranged from <5.0 to 6.18 (ig/L. Concentrations of both total and dissolved Nickel reported in monitoring
wells are less than the groundwater action level. Comparison of total and dissolved values in the monitoring
wells suggests that Nickel is predominately dissolved in GW04 and GW05.
Selenium -The identified groundwater action level for Selenium is 50 (ig/L. The 2020 analytical results
for total and dissolved Selenium were all reported as <5.00 (ig/L with the exception of GW04, which had
a concentration of 5.68 (ig/L. All values were consistent with the range of values reported previously at
the sampled locations. None of the reported values exceeded the groundwater action level.
Sodium - There is no groundwater action level identified for Sodium. There is a Recommended Guideline
Value of 800,000 (ig/L of Sodium for livestock watering. Concentrations of total and dissolved Sodium
reported for 2020 range from 22,400 (GW05 dissolved) to 72,400 (GW04 dissolved) (.ig/L and are
consistent with values reported previously at the sampled locations. None of the current or previous
concentrations are greater than the guideline value for livestock watering. Comparison of the total and
dissolved values at each sample location suggests that the Sodium is predominately in the dissolved state.
Zinc - The identified groundwater action level for Zinc is 2,000 (ig/L. For 2020, total and dissolved Zinc
concentrations were reported as <20.0 (ig/L for all the sampled locations. The reported total and dissolved
Zinc concentrations are less than the groundwater action level, and are within the ranges of previously
reported values.

Phenols - The identified groundwater action level for Phenols is 2,000 (ig/L. Total Phenols reported in the
2020 monitoring event were less than the detection limits of each respective sample. Detection limits
ranged from 18.4 to 20 (ig/L. Phenols have not been detected since monitoring of the site began.
Tables 1A through IF (Appendix I) summarize the analytical results for the groundwater samples
collected. The tables have been organized to enable comparison of the analytical results for the various
monitoring events at each sample location. The tables also include a summary of the previously obtained
analytical data for each sample location, based on a table prepared by Geraghty and Miller that was included
in the Red Oak Landfill Superfund Site RI Report. Copies of the 2020 laboratory reports are included in
Appendix E. The analytical data is also presented by parameter in graphic form in Appendix I.
The Target Analyte Short List of parameters was originally monitored on an annual basis, with the Full List
being monitored on a 5-year rotation. The most recent data does not suggest that expansion of the
monitoring program to include more frequent analysis of the full Analyte List is warranted. Rather, the
2020 analytical results support the 2014 change to biennial sampling, with four (4) to six (6) year sampling
of the Full Target Analyte List, because no major changes were observed in the ranges of contaminant
concentrations or contaminant trends for the analyzed parameters. In accordance with this schedule, the
full Target Analyte List will be sampled in 2026.
4.2 Surface Water Sampling
4.2.1 General Information
In accordance with approved modifications to the MOMP, surface water sampling was conducted during
the 2020 monitoring activities. Surface water samples were collected on July 27, 2020 and September 23,
2020 at two (2) locations along the west bank of the East Nishnabotna River. Samples SW01 and SW02
were collected downstream and upstream of the landfill, respectively. The sample locations are described
below:
• Sample location SW01 was located on the west bank of the river south of the southeast corner of
the landfill.
• Sample location SW02 was also located on the west bank of the river. The sample location was
approximately 200 feet upstream of the north landfill outfall to the river. The location was
approximately 50 feet downstream of the river's confluence with the creek north of the landfill.
On the dates the samples were collected, the river was flowing and turbid. The river level was considered
normal during the July and September sampling events. Water was estimated to be approximately one (1)
to three (3) feet deep at the sample locations.
Other general information regarding the surface water sampling is contained in the Site Monitoring Log
Book.
4.2.2 Procedures
Surface water samples were collected in accordance with the following procedures.
Sample Collection
Specific information regarding sampling sequence at each sample location is provided in the Site
Monitoring Log Book. Samples were collected for analysis of the following target compounds and were
collected in the order below:

o Target Analyte List - Inorganics (Dissolved);
o Target Analyte List - Inorganics (Total);
o Target Compound List - Volatile Organic Compounds (TCL-VOCs)
The Target Analyte Full List of parameters, as presented in Appendix H, was analyzed in 2020. This list
of parameters includes: Aluminum, Antimony, Arsenic, Barium, Beryllium, Cadmium, Calcium,
Chromium, Cobalt, Iron, Lead, Magnesium, Manganese, Mercury, Nickel, Potassium, Selenium, Silver,
Sodium, Thallium, Vanadium, Zinc, and Cyanide (total only) as well as Phenol, and the Target Compound
List - Volatile Organic Compounds (TCL-VOCs).
Due to the depth and flow of the river at the sample locations, the surface water samples were collected
using a bottom loading pressure bailer and the samples were transferred to the appropriate sample
containers. Water entered the bailer from the bottom and it was not fully submerged during the sample
acquisition process.
VOC samples were poured into 40 ml VOA vials until a positive meniscus formed at the vial opening. The
cap was placed on the vial and tightened carefully so that no air bubbles were entrapped in the sample vials.
Care was taken to avoid dilution of the preservative in the sample container.
Samples for Dissolved Inorganics analyses were collected in a bailer (Voss Technologies) and filtered
through an in-line, disposable, 0.45 micron filter cartridge attached directly to the bailer. The sample was
collected directly from the bailer/filter assembly into the sample container.
Sample Packaging
Prior to sample acquisition, the sample containers were labeled. Following sample acquisition, the filled
sample containers were dried and placed in coolers with ice. VOC sample vials were placed in preformed
foam containers prior to being placed in the cooler.
Upon completion of the sampling on July 27, 2020 and September 23, 2020, the samples were taken back
to ATC's Des Moines, Iowa office, then the samples were refrigerated at 4±2 degrees Celsius. The samples
were repacked with ice in a large cooler along with the completed Chain-of-Custody. A Custody Seal was
affixed to the cooler and it was picked up the following morning (July 28th and September 24th) by a Eurofins
TestAmerica courier for delivery to Eurofins TcstAmcrica's laboratory located at 3019 Venture Way, Cedar
Falls, Iowa. A copy of the Chain-of-Custody is included with the laboratory analytical report in Appendix
E.
Equipment Decontamination
There was no equipment used that required decontamination during the surface water sampling.
Investigation Derived Waste Management
Based upon the results of previous site sampling, investigation derived solid waste was disposed of as
common non-hazardous solid waste off site.
Field Sampling OA OC
Coolers, provided by Eurofins TestAmerica Laboratories, for the 2020 sampling event contained laboratory
prepared trip blanks for VOCs. These blanks accompanied all of the coolers containing sample containers
or surface water samples to be analyzed for chemicals of concern.

4.2.3 Sampling Problems or Variances from MOMP
Discussion of problems associated with total Cyanide sampling is included in Section 4.1.3,
The following minor variance from the MOMP was made in the field:
• Temperature, pH, and conductivity was not collected from the surface water sampling.
Temperature, pH, and conductivity are not commonly utilized during data analysis of surface waters at the
Site, thus this modification should not have any effect on sample integrity or analytical results. Care will
need to be exercised to assure that the surface water field parameters are collected during future monitoring
events.
4.2.4 Analytical Summary
The following paragraphs summarize analytical results of surface water sampling conducted at the Site in
2020.
Volatile Organic Compounds (VPCs)
Evidence of VOC impact has only been previously observed once in surface water samples since monitoring
was initiated in the spring of 2001 (See Tables 2A and2B [Appendix I]). In 2018, a concentration of 1.14
(.ig/L of 1,2-dichloroethane was detected in sample SW02 (upstream sample). There is no identified surface
water action level for 1,2-dichloroethane. Surface water samples obtained in 2020 contained no detections
of any VOCs in either the upstream or downstream sample, suggesting that the 2018 detection was either a
false positive detection, or an isolated event likely caused by a source upstream of the landfill.
Metals and General Chemistry Parameters
Results of total and dissolved element/metals analyses collected to date are summarized by Tables 2A-C
(Appendix I). Results from the 2020 monitoring event were mostly consistent with concentration ranges
reported previously. Discussion of the 2020 sampling results is below.
Aluminum - The identified surface water action level is 87 (ig/L. For 2020, the total and dissolved
Aluminum concentrations reported were <50 (ig/L for SW01 and SW02. The historic difference in
total and dissolved concentrations indicates that the majority of aluminum has been present as
particulate. Total Aluminum values do not exceed the action level, for the first instance since
monitoring began in 2001. In 2019 dissolved Aluminum was detected for the first time since 2003.
The 2020 samples indicate that the dissolved Aluminum concentration has returned to a value below
Monitoring, Operation, and Maintenance Report - 2020 page | 20

-AN ATLAS COMPANY—
the laboratory detection limit. The return of dissolved phase Aluminum to concentrations below the
RL, and the reduction of total Aluminum from the 2019 value of 17,000 (ig/L (SW01), support the
interpretation put forward in 2019 that the anomalously high concentrations of surface water samples
were the result of record flooding in southwest Iowa.
Arsenic - The identified surface water quality action level for Arsenic (as As+3) is 0.018 (ig/L. The
2020 total Arsenic concentrations in the river were reported as 2.66 and 2.69 (ig/Lfor SW01 and SW02,
respectively. Dissolved Arsenic concentrations were reported as 2.59 and 2.71 (ig/L for SW01 and
SW02, respectively. The samples are consistent with previous concentrations, with the exception of
the elevated downstream total Arsenic concentration from 2019. The majority of Arsenic appears to
be present in the dissolved phase in both sample locations. The upstream (SW02) and downstream
(SW01) samples are both greater than the surface water action level. However, the results from the two
sample locations are similar to each other. These results are consistent with previous interpretations
that the source of the Arsenic concentrations is located upstream of the landfill, and that the elevated
2019 total arsenic results were caused by record flooding.
Barium - The identified surface water action level for Barium is 1,000 (ig/L. The reported total Barium
concentrations for 2020 were 136 and 133 (ig/L for SW01 and SW02, and the reported dissolved
Barium concentrations were 132 and 136 (ig/L, respectively. All concentrations are below the
identified action level. The reported dissolved values and upstream total value are consistent with
previously reported results. The upstream and downstream concentrations are similar to each other,
indicating that Barium is not leaching from the landfill Site.
Cadmium - The identified surface water action level for Cadmium is 0.25 (ig/L. The 2020 total and
dissolved Cadmium concentrations of both samples were not detected above the RL of 0.1 (ig/L. The
results support the interpretation that the 2019 total Cadmium detection was an anomalous result of the
2019 flooding. The 2020 Cadmium samples do not exceed the identified action level.
Chromium - There is no surface water action level identified for total Chromium, however there is a
surface water action level for hexavalent chromium of 11 (.ig/L. In 2020, dissolved and total Chromium
was not detected above the RL (5 j^ig/L). The results further support the interpretation that the 2019
detections were caused by the 2019 flooding. The 2020 Chromium samples do not exceed the identified
action level.
Cobalt - The surface water action level identified for Cobalt is 24 (ig/L. During the 2020 sampling
event, total and dissolved Cobalt were not reported above the RL (0.5 j^ig/L). The results are consistent
with previous analytical data, and support the interpretation that 2019 concentrations were anomalous.
All Cobalt concentrations are below the action level.
Iron - There is no identified surface water action level for Iron. The total and dissolved Iron
concentrations for the 2020 sampling were reported to be below the RL of 100 (ig/L. The results
suggest that the high concentrations detected in 2019 were anomalous values.
Manganese - The identified surface water action level for Manganese is 50 (ig/L. Total Manganese
concentrations in the 2020 samples were reported as 26.5 and 24.1 (ig/L for SW01 and SW02,
respectively. Dissolved Manganese concentrations were reported as 27.6 and 26 (ig/L for SW01 and
SW02. The detected total Manganese concentrations are less than the surface water action level. The
similarity between the total and dissolved concentrations indicates that the majority of Manganese is
present as in the dissolved phase.

Nickel - The surface water action level identified for Nickel is 52 (ig/L. Dissolved and total Nickel
was not detected above the RL (5 j^ig/L) during the 2020 sampling event. The RL is less than the
identified action level. The results support the interpretation that the 2019 elevated concentrations were
anomalous.
Selenium - The identified surface water action level for Selenium is 5 (ig/L. Both total and dissolved
Selenium were not detected above the RL (<5 j^ig/L) during the 2020 sampling event. The results are
less than the surface water action level.
Sodium - There is no surface water action level identified for Sodium. Concentrations of total and
dissolved Sodium in the 2020 samples range from 9,780 to 10,200 (ig/L. None of the reported values
were greater than the 800,000 (ig/L Recommended Guideline Value for livestock watering. The sodium
concentrations are consistent with historic values since monitoring began in 2001.
Zinc - The identified surface water action level for Zinc is 120 (ig/L. Dissolved and total Zinc were
not detected above the RL (20 j^ig/L) or action level in the 2020 samples. The 2020 results were
consistent with previous concentrations.
Tables 2A - 2C (Appendix I) summarize the analytical results for the surface water samples collected to
date. The tables have been organized to enable comparison of the analytical results for the various
monitoring events at each sample location.
In 2019, downstream and upstream sample concentrations were generally elevated above the majority of
historic values, particularly the previous five (5) years. The 2020 results support the interpretation that the
2019 concentrations were anomalously increased above historic values as a result of the record rainfall and
flooding that occurred in southwest Iowa. Additionally, downstream concentrations are no longer
significantly elevated above the upstream concentrations as was seen during 2019. The similarity in sample
concentrations suggests that if runoff from the landfill site entered the stream during, or shortly after, the
2019 high water event, the source is no longer impacting surface water quality during 2020.

4.3.1 General Information
The stabilization of the Riverbank Slope was approved by EPA Region 7 on November 19, 2002. The
monitoring and maintenance activities associated with the Riverbank Slope, as defined in the Consent
Decree, have subsequently become the responsibilities of the City and Magna.
ATC personnel observed the condition of the Riverbank Slope on two (2) occasions to date during 2020.
The observation dates were:
• April 1, 2020: During the spring slope observation event, assessment of changes to the slope by
observations from the east bank of the Nishnabotna River and a walking reconnaissance of the
slope was completed. The assessment was conducted by Mr. Eric Brown of ATC's Des Moines,
Iowa office.
• October 19, 2020: During the fall slope observation event, assessment of changes to the slope by
observations from the east bank of the Nishnabotna River and a walking reconnaissance of the
slope was completed. The assessment was conducted by Mr. Eric Mueggenberg and Mr. Doug
Sayer of ATC's Des Moines, Iowa office.
Photographs depicting the slope conditions on the referenced dates are included in Appendix A.

As noted, the Riverbank Slope is observed from the opposite side of the river in the spring and late fall.
Previously, four (4) vantage points were marked on trees on the opposite river bank using spray paint and
were marked with electric fence posts. However, as of July 30, 2015 the four (4) vantage points could not
be found. For 2017, ATC established three locations via GPS coordinates to photograph the Riverbank
Slope. Utilizing GPS locations removes the potential for physical markers to fade or be accidently moved
accidently. See the field notes for the three (3) locations. The Riverbank Slope is photographed directly
across, upstream, and downstream of these locations.
The increased monitoring of the Riverbank Slope is in response to surface sloughing and movement of the
Riverbank Slope area during the June 2007 monitoring activities and subsequent slope observations through
November 2007. Those observations and conditions were summarized in the 2007 Monitoring, Operation
and Maintenance Report prepared for the landfill. Movements continued throughout 2008 in apparent
response to heavy rainfall events. Surface movement or sloughing on large sections of the slope had not
been observed since 2008 until surface sloughing of the downstream portion of the slope was observed in
April of 2012. The most recent period of significant erosion occurred between Markers #1 and #3 during
2018 due to heavy rainfall between August and October. The 2018 erosion observations were summarized
in the 2018 Monitoring, Operation and Maintenance Report.
The Riverbank Slope is also observed via a walking survey in the spring and fall to document the slope
condition and identify the location of any apparent seeps or slope distress. The slope is also observed in a
cursory manner during summer monitoring activities. These surveys are conducted by generally traversing
the toe, intermediate and upper portions of the slope to observe vegetative cover, tree establishment,
evidence of seepage, erosion channel development and evidence of continued distress on the slope. The
extent of the survey, particularly in the summer, is dictated by vegetative cover, which tends to mask erosion
channels, cracks and other obstructions on the slope and results in personnel safety concerns.
Generalized features of the Riverbank Slope and the location of seep samples are depicted on attached
Figure 3.
During the onsite slope reconnaissance, there were a number of planted and volunteer trees present on the
slope surface. The slope was overall well vegetated with remnants of the last season's growth and sprouting
new spring growth was beginning at the time of the April 1st visit. On the date of the October slope
reconnaissance, the slope was well vegetated and areas of previous soil erosion appeared to have
reestablished much of their vegetative cover.
The April 1, 2020 slope reconnaissance from the opposite bank of the river did not identify any evidence
of slope movement over the winter or early spring. Additionally, no significant new erosion or slope
movement was identified during the November 19, 2020 slope reconnaissance.
The areas of previous erosion between Markers #1 and #3, which are identified on the attached Figure 3,
are still identifiable by the topographical changes to the slope; however, they have recovered sufficient
vegetation over the summer of 2020 to make their vegetative cover near indistinguishable from the
surrounding slope in the imagery. A small scarp, which has been present on the slope since at least 2006,
remains near the slope edge near Markers # 1 through Markers #3. The scarp does not appear to have
increased in size since 2019. The slope, and associated vegetation, appeared to be in generally good
condition from other vantage points.
Conditions on the upper slope during each site visit were generally consistent with those that have been
reported previously, with the exception that vegetation growth has become sufficient to cover and stabilize
areas of historical slope movement. Examination of the slope did not identify new zones of apparent

activity. No evidence of landfill materials has been observed in any of the exposed slope surfaces.
Observation of the landfill cap and cap drainage system suggested it was in good overall condition.
During the July 27, 2020 and September 23, 2020 sampling activities, no slope observation activities were
performed.
4.3.2 Markers
Marker signs, visible from the opposite side of the river were installed by the City in August 2011 on the
crest of the Riverbank Slope to facilitate documentation of the condition of the slope. These signs were
installed at approximately 100 foot intervals, starting near the tree line on the downstream limit of the
landfill to a point approximately even with EDS upstream, a distance of approximately 867 feet. The
markers are numbered sequentially from 1 to 10 from downstream to upstream. Photographic
documentation of representative installations is included in Appendix A. Approximate marker locations
are depicted on the attached Figure 4.
The approximate distance between the markers is summarized by the following table:

The distance between markers varies somewhat from the general 100 foot separation due to the presence
of obstructions, including trees and bushes, near the crest of the slope which were likely to obstruct visibility
from below and across the river.
4.4 Landfill Seep/Spring Sampling
4.4.1 General Information
An area of seepage immediately above the river in the area below the location of former monitoring well
GW02 was first identified in June of 2007. This area of seepage was also observed in the fall of 2007 and
during the 2008 monitoring events. Slope inspections conducted during 2009 did not identify the presence
of this area of seepage nor were any others identified. This area of seepage was again present during site
monitoring activities from 2010 through 2013. This seep, or spring, identified as SS01/SS02 has been
sampled in 2007, 2008 and 2010 to 2020 monitoring events. Considerable erosion and sloughing has been
observed in the bank above the seep/spring over the period it has been observed.
Seep/spring sample location SS-01 was active at the time of the July 27, 2020 and September 23, 2020
sampling activities. The flow rate during the 2020 sampling events was estimated at 0.5 gallon per minute.
The seep/spring was sampled on the previously mentioned dates in conjunction with surface water sampling
activities.

4.4.2 Procedures
Sample Collection
To facilitate the seep sampling, a small pit and dam was constructed in the seep discharge channel to allow
water to accumulate sufficiently to sample. Sediment stirred up by this activity was allowed to settle and
dissipate prior to sampling. A small flat stone was placed in the wall of the pit to allow direct collection of
the water samples into a downslope bailer/filter apparatus. Samples for VOC, total metals, and dissolved
metals analyses were collected directly from the bailer/filter apparatus into containers without excessive
aeration and agitation. Samples were collected in the following order:
o Target Analyte List - Inorganics (Dissolved);
o Target Analyte List - Inorganics (Total);
o Target Compound List - Volatile Organic Compounds (TCL-VOCs)
Samples for VOC analysis were collected in a manner consistent with other VOC samples on the site such
that no air bubbles were entrapped in the sample container. Care was taken to avoid dilution of the
preservative in the sample container.
Sample Packaging
Following sample acquisition, the sample containers were dried, labels completed, and the containers
packaged in an iced cooler. VOC sample vials were placed in preformed foam containers prior to being
placed in the iced cooler.
Upon completion of sampling, the samples were taken back to ATC's Des Moines, Iowa office, then the
samples were refrigerated at 4±2 degrees Celsius. The samples were repacked with ice in coolers along
with the completed Chain-of-Custody. A Custody Seal was affixed to the cooler and it was picked up the
following morning (July 28th and September 24th) by a Eurofins TestAmerica courier for delivery to
Eurofins TcstAmcrica's laboratory located at 3019 Venture Way, Cedar Falls, Iowa. A copy of the Chain-
of-Custody is included with the laboratory analytical report in Appendix E.
Equipment Decontamination
No equipment decontamination was necessary.

Discussion of problems associated with total Cyanide sampling is included in Section 4.1.3,
4.4.4 Analytical Summary
Analytical results from sampling of the seep/spring location are summarized by the following narratives
and are included in Table 3 in Appendix I.
Volatile Organic Compounds (VPCs)
VOC analyses of seep samples collected from the SS-01/SS-02 area since 2007 have historically identified
low concentrations (usually less than 10 (ig/L) of Tetrachloroethene (PCE), Trichloroethene (TCE), total
1,2-Dichloroethene (DCE), and Vinyl Chloride. Exceptions to these low concentrations include the SS-02
duplicate sample from 2013, SS-01 and SS-02 from 2015, and the SS-01 sample from 2016. The 2020
sampling of seep/spring location SS-01 did not result in any detections above the laboratory RLs. A
complete list of VOCs that were analyzed can be found in Table 3 of Appendix I.
Metals and General Chemistry Parameters
Tables 2 and 3 from the Third Five-year Review Report included in Appendix F summarize the identified
surface water and groundwater action levels applicable to monitored metals and general chemistry
parameters at the Red Oak Landfill.
Concentrations of total and dissolved metals reported for the 2020 seep/spring sample were generally
consistent with the range of values reported since the seep/spring area was first sampled in June of 2007.
Total Manganese, which was reported to have the lowest concentration to date, was an exception to the
general pattern. Discussion of the 2020 sampling results are contained in the following paragraphs.
Aluminum - The identified surface water action level is 87 (ig/L and the groundwater action level is
16,000 (ig/L. For 2020, the total and dissolved Aluminum concentrations reported at the seep/spring
location were both below the laboratory RL of 50 (ig/L. 2020 marks the fifth consecutive year that the
dissolved Aluminum concentration was lower than the laboratory RL. No action levels were exceeded
in the 2020 values.
Arsenic - The identified surface water quality action level for Arsenic (as As+3) is 0.018 (ig/L and the
identified groundwater action level is 0.02 (ig/L. The 2020 total and dissolved Arsenic concentrations
for the seep/spring location were reported as <2 (ig/L. Both parameters returned to concentrations
below the RL after being detected in 2019. The RL is greater than the identified action levels, thus it
cannot be determined if Arsenic concentrations exceed either action level.

n
Barium - The identified surface water and groundwater action levels for Barium are 1,000 and 2,000
(ig/L, respectively. The reported total Barium concentration for 2020 was 94.8 (ig/L, and the reported
dissolved Barium concentration was 93.9 (ig/L. The reported values are less than either action level.
Cadmium - The identified surface water and groundwater action levels for Cadmium are 0.25 (ig/L
and 5(.ig/L. respectively. Total Cadmium and dissolved Cadmium were not detected at concentrations
above the RL of 0.1 (ig/L. Neither total Cadmium, nor dissolved Cadmium exceeds the identified
action levels.
Chromium - There is no surface water action level for total Chromium, however there is a surface
water action level for hexavalent chromium of 11 (.ig/L. The groundwater action level for Chromium
is 100 (ig/L. The 2020 total and dissolved Chromium concentrations were not detected above the RL
of 5 (.ig/L. The reported total Chromium result and the RL for dissolved Chromium are both less than
the identified action levels.
Cobalt - The surface water action level reported for Cobalt is 24 (ig/L. The groundwater action level
is 4.7 (ig/L. During the 2020 sampling event, total Cobalt was not detected above the RL (0.5 j^ig/L).
The reported results and the RL are less than the groundwater and surface water action levels.
Iron - There is no identified surface water action level for Iron. The groundwater action level is 11,000
(.ig/L. The total and dissolved Iron concentrations in 2020 were reported to be <100 (ig/L. These
concentrations are less than the groundwater action level.
Manganese - The identified action levels for Manganese are 50 and 300 (ig/L for surface water and
groundwater, respectively. The total Manganese concentration in the 2020 seep/spring sample was
reported to be 39.7 (ig/L and dissolved Manganese was reported at 38.2 (ig/L. The 2020 total
Manganese concentration is the lowest detected value since sampling began in 2007. Neither detected
Manganese concentration was greater than the identified action levels.
Nickel - The surface water and groundwater action levels identified for Nickel are 52 and 100 (ig/L,
respectively. Total and dissolved Nickel concentrations were not detected above the RL of 5 (ig/L
during the 2020 seep/spring sampling event. The Nickel RLs are less than either of the identified action
levels.
Selenium - The identified surface water action level for Selenium is 5 (ig/L. The groundwater action
level is 50 (ig/L. Both total and dissolved Selenium were not detected above the RL (5 j^ig/L) during
the 2020 sampling event. The results are less than both action levels.
Sodium - There are no surface water or groundwater action levels identified for Sodium. Total Sodium
was detected at 30,200 (ig/L, and dissolved sodium was detected at 30,400 j_ig/. None of the reported
values were greater than the 800,000 (ig/L Recommended Guideline Value for livestock watering. Both
Sodium values are consistent with values reported in previous years.
Zinc - The identified surface water and groundwater action levels for Zinc are 120 and 2,000 (ig/L,
respectively. Total Zinc was not detected above the RL (20 j^ig/L) in the 2020 seep/spring samples.
The 2020 seep/spring concentrations are less than either of the identified action levels.
Based upon analytical results of samples obtained from seep/spring location SS-01/SS-02 from 2007
through 2020, the identified seep/spring is not a significant source of contaminants of concern to the East
Nishnabotna River.

In the 2019 report, high concentrations of contaminants of concern, particularly non-dissolved
contaminants, were detected from the seep and downstream samples, potentially indicating that the seep
had become a significant source of contamination. However, the presence of higher particulate
concentrations in the surface water sample than in the seep sample led ATC to interpret that floodwaters
potentially caused erosion of sediments surrounding the landfill, which contain elevated concentrations of
the contaminants of concern, and deposited these sediments into the Nishnabotna River basin near the
landfill and along the slope. The deposition of these flood related sediments was believed to be the source
of the increased seep and downstream concentrations. The 2020 results support the flood deposition
interpretation.
Continued surface water and seep sampling is recommended to further support or refute the interpretation
of a single anomalous event in 2019.
4.5 Annual Groundwater Use Review
On October 19, 2020 ATC personnel made a driving survey of the area generally within a two (2) mile
radius of the landfill to identify new construction or development within the area. Due to the absence of
rural water systems in the area, it is inferred that such development would also likely include the installation
of a well for water supply purposes. No new industrial or commercial activity was observed within the
two-mile area of interest during the area reconnaissance. Development was consistent with that observed
during the initial groundwater use survey completed during December of 2001 and modified as necessary
during the 2002 and 2003 area surveys.
ATC attempted to contact the Montgomery County Sanitarian, who is responsible for issuing well
construction permits and abandonment documentation within the county, via email and an online request
form. As of the date of this report, ATC has not received a response from the Sanitarian. Upon receipt and
review of any response, ATC will forward any pertinent information that changes the
conclusions/recommendations of this report. Documentation can be found in Appendix H.
4.6 Inclinometer Survey
As part of on-going monitoring of the Riverbank Slope, Magna has elected to include annual gauging of
inclinometer INC 1, installed in the fall of 2009 by Energizer, in the monitoring activities.
The inclinometer was gauged on September 23, 2020 by Mr. Eric Brown of ATC. Information regarding
the survey is recorded in the Site Monitoring Logbook and data sheets, graphs are included in Appendix
G. Calibration information provided with the probe and inclinometer casing orientation information as
provided previously by RSV Engineering are also included in that Appendix. The survey was conducted
using a Slope Indicator inclinometer probe (S/N 25685) and Datamate datalogger in accordance with Slope
Indicator standard procedures. The data was analyzed and compared to previous data using Microsoft
Excel. Photographs from 2011 depicting the survey setup are included in Appendix G.
Data from the September 2020 gauging was compared with datasets obtained since 2009. Review of Axis
A (Perpendicular to the slope) indicates that the data obtained previously during 2019 was anomalous. The
2020 Axis A profile closely resembles the 2018 profile. The slope has shifted towards the East Nishnabotna
River at all depths greater than 3" below grade. The maximum movement of approximately 0.5 to 0.6
inches has occurred at 23" below grade. Deviation of the 2020 data from the original 2009 dataset becomes
greater than 0.25 inches below 15" below grade. The 2020 data converges back to within 0.25 inches of
the original dataset at approximately 35" below grade.
Monitoring, Operation, and Maintenance Report - 2020 page | 28
204EM02915
February 2021
-------
Results from Axis B are similar to those obtained in 2019, suggesting that the 2019 and 2020 deviation is
not anomalous. The 2020 data indicates that approximately 0.25 inches of movement have occurred at all
depths since 2019. The slope below 3' below grade has continued to shift to the north in the vicinity of the
inclinometer. According to the results, the maximum deflection of approximately 2 inches has occurred at
20 feet below grade. The inclinometer profile converges towards the original 2009 dataset at greater depths
where only 0.4 inches of deviation has occurred at 37' below grade.
During inclinometer gauging and the fall slope observation, ATC inspected the inclinometer and bollards
for signs of potential damage. No damage was observed on the inclinometer and bollards. Additionally,
attention was paid to the slope and cap surfaces during the fall slope inspection. No indications of cracks,
slumps, or other slope failures were evident in the vicinity of the inclinometer. Furthermore, the
observations of the slope bank from across the river
The anomalous values observed in the 2019 inclinometer data are not present in the 2020 Profile A, however
they remain in Profile B. The lack of visual evidence of damage to the inclinometer, or cracks/slumps in
the vicinity of the inclinometer, indicate that the Site is not experiencing slope failure. In 2019, the
inclinometer anomalies were interpreted as soil swelling caused by the record precipitation and river levels
near the Site. The return towards baseline values in Profile A supports the 2019 interpretation. If soil
swelling was the cause of the 2019 values, the 2020 Profile B dataset may represent a new baseline caused
by settlement of contracting soils during 2020's moderate drought conditions after the 2019 precipitation
event. Continued monitoring of Profile B is necessary to determine the cause of the shift in the dataset. At
this time, ATC does not consider the described inclinometer deflections to be caused by deep-seated
movement in the subsurface.

5.0 RECOMMENDATIONS
The 2020 site monitoring activities included groundwater sampling, surface water sampling, and sampling
from the seep/spring.
It is recommended that continued observation of the Riverbank Slope be performed at least semi-annually
to document changes in slope integrity and the establishment of stabilizing vegetation. Slope observation
activities should be conducted by ATC, or Magna's Representative, during the spring, prior to the onset of
annual vegetation growth, and in the fall, following the first hard frost. Additionally, the Slope condition
should be observed by the City of Red Oak during summer Operations and Maintenance activities. It is
recommended these observations continue to include photographic documentation of the Slope conditions
as observed from the east bank of the river, as well as from the top of the slope.
The area of seep/spring sample location SS-01 should be monitored for evidence of discharge during each
site visit and samples should be collected and analyzed annually if sufficient water is present. When it is
present, the seep/spring should be analyzed for VOCs and the Target Analyte Short List, unless the
monitoring schedule dictates that the Full Analyte List is to be sampled.
Monitoring well GW02R should continue to be checked annually for the presence of water during routine
site visits and sampled if sufficient water is present. Decisions regarding purging of the well prior to
sampling will be addressed with Magna and EPA prior to sampling and may be largely dependent on the
quantity of water present in the well. The next monitoring event, which will take place in 2021, does not
include plans for sampling of the monitoring wells at the site.
During the next Five-Year Review, the currently identified Surface Water Action Levels and Groundwater
Action Levels should be discussed with the USEPA Proj ect Manager to determine if they are still acceptable
to meet the project goals. This recommendation is driven by changes to EPA water quality standards for
some target parameters since the establishment of the current Action Levels. If the project manager
determines that action levels should be updated, the update should be performed in conjunction with the
next Five-Year Review.
Inclinometer INC 1, installed by Energizer, should continue to be monitored as part of the annual Site
monitoring activities until trends in the slope condition, particularly Profile B, can be established. Results
should be compared to historical deflections.

6.0 SUMMARY OF FINDINGS
6.1 Groundwater Samples
• Detections of 1,2-dichloroethene (total) and vinyl chloride did not exceed Action Levels.
• Arsenic (total & dissolved) was detected above the Action Level in groundwater samples. No trend
is yet apparent for Arsenic concentrations.
• Cobalt (total & dissolved) was detected above the Action Level at GW05; consistent with historical
data.
• Iron (total & dissolved) and Manganese (total and dissolved) was detected above the Action Level
at GW03 and GW05. No trend is yet apparent for the concentrations.
6.2 Surface Water Samples
• No VOCs were detected in surface water samples during 2020.
• Inorganics concentrations that were anomalously high during 2019 returned to historical ranges
during 2020, supporting the interpretation that 2019 concentrations were caused by record flooding.
• Arsenic (total & dissolved) was detected above the Action Level, at similar concentrations, in
upstream and downstream samples, supporting the historical interpretation of an upstream source.
6.3 Seep/Spring Samples
• No VOCs were detected in the seep sample during 2020.
• Arsenic was not detected in the seep sample; however, the laboratory RL (2 j^ig/L) is greater than
the surface water and groundwater Action Levels (0.018 (ig/L & 0.02 j^ig/L).
• The seep/spring does not appear to be a significant source of contaminants to the river.
6.4 Stabilized Riverbank Slope Observations
• Areas of erosion are still identifiable between markers #1 and #3; however, they have recovered
most of their vegetative cover. The scarp associated with the erosion remains visible and does not
appear to have grown since 2019. The remainder of the slope appears to be in good condition.
• The landfill cap and drainage system appears to be in good condition.
6.5 Annual Groundwater Use Review
• No activity consistent with new groundwater usage was observed in a 2 mile radius of the landfill.
6.6 Inclinometer Survey
• Profile A has returned towards baseline values, supporting the 2019 interpretation of swollen soils
as a result of record precipitation and flooding.
• Profile B resembles the 2019 departure from historical values, possibly indicating a new baseline
caused by settlement of soils in moderate drought conditions after record flooding. Continued
monitoring of Profile B is necessary to determine the cause of the 2019 & 2020 shift.
• At this time, inclinometer deflections are not considered to be caused by deep-seated movement of
the slope subsurface.

Kansas City, Kansas; 66101
Subject; Requested Modifications to Monitoring, Operations, and Maintenance Plan* for
Red Oak Landfill Superfund Site, Red Oak, Iowa
Dear Mr. Stewart:
It is ATC's understanding that we will be conducting the routine groundwater and surface water
sampling at the subject' site for the first two years of the 30-year monitoring period.
Consequently, ATC Associates Inc. on behalf of our client, Magna International Inc., would like
to request the following modifications to the Monitoring Operation and Maintenance Plan
(MOMP) for the Red Oak Landfill Superfund Site in Red Oak, Iowa,
The requested modifications pertain to Subsection 7,5 (Groundwater Sampling) of Section 7.0
(Monitoring Activities) of the Field Sampling Plan (FSP) portion of the MOMP. The first is
regarding the substitution of disposable polyethylene bailers for disposable Teflon bailers in the,
monitoring well purging and sampling process. The second pertains to the field filtration of the
water samples.
The justification for the first substitution follows;
Historically, very low concentrations of volatile organic compounds (VOCs) (typically less than
or near the analytical method detection limit) have been identified in the site groundwater. The
. one exception, toluene at a concentration ranging from 25 to 65'jig/L, is routinely sampled using
polyethylene bailers at LUST sites with no apparent adverse effects. At the previously identified
concentrations, it is unlikely that the VOCs present at the site will have any significant deleterious
effect on the polyethylene.
The contact period between the sampled media (water) and the bailer will be very short Due to
the short contact time, there will be minimal potential for the VOCs-present in the groundwater to
either leach, compounds from or react with the polyethylene.
Metals samples, both, total and dissolved, to be collected at the site will be stored in polyethylene
containers. The polyethylene .bailer will have no -impact on the integrity of these samples.

Omaha, Nebraska 68144
www.atc-enviro.com
402.697.9747
Fax 402.697.9170
Due to these observations, it is ATCs opinion that it is unlikely the polyethylene bailer will have
any significant deleterious effect on analytical results at the site.
-------
Mx, Robert L. Stewart, U.S. EPA
May 14,2001
Page Two
If analytical results for YOCs are significantly different (higher) than those previously identified
at the site and potential leaching or reaction with the polyethylene becomes a concern, teflon
bafler(s) can be substituted to sample those wells identified as having high VOC -concentrations
during the next sampling event.
Subsections 7.6.1 and 7.7.1 (Equipment) of Sections 7.6 (Groundwater Sampling) and 7.7
(Surface Water Sampling) of the FSP specify the use of a "Field Filtering Kit5. Sections 7.5
(General Sampling Procedures) of the FSP and Section 7.0 (Sampling Procedures) of the Quality
' Assurance Project Plan (QAPP) provide the following procedure for field filtration of the metals
samples.
"For samples to he analyzed for dissolved metals, collect the sample into an unpre served
sample container. Assemble the field filtering Mt using a new disposable two-piece
funnel and reservoir unit and a new disposable 0.45-micron filter disk. Pour the sample
from the unpreserved sample container into the upper "mouth" of the funnel unit.
Generate a vacuum with the hand pump until a sufficient Volume of water has passed
through the filter into the bottom reservoir. Transfer the contents of the bottom reservoir
into the appropriately preserved sample container. Replace the filter disk...."
ATC is proposing utilization of the recently available polyethylene "pressure bailers with in-line
disposable filter cartridges for field filtration operations. Advantages would be simplification of
the filtration process, lower potential for the sample to be cross contaminated since it will be
transferred directly from the bailer to the sample container, and potentially, a reduction in the
quantity of investigation derived solid waste, assuming the pressure bailers work satisfactorily for
purging operations.
Magna International Inc. and ATC Associates Inc. appreciate BPA's assistance and consideration
of these MQMP modifications. Please feel free to contact me at (800) 873-5532 with any
questions.

Dear Bill:
' This letter is in response to your letter of May 14, 2001, concerning minor modifications to
the Monitoring, Operation and Maintenance Plan for the Red Oak Landfill Superfine! Site. You
requested the substitution of disposable polyethylene bailers for disposable Teflon bailers, the
use of pressure bailers with in-line disposable filters, and the deletion of the requirement to use
Teflon leaders with the bailers, based oil their scarcity.
We hereby agree with your requests, subject to the condition, you proposed in the letter that
if the analytical results are significantly higher than the previous measurements at the' site, teflon ,
will be substituted at the next sampling event
If yon have further questions about this letter, please call me at 913-551-7 654. Otherwise,
we will meet you about 9:00 am on Wednesday, May 23 at the Red Oak site to observe the round
of sampling. We are especially interested in the bailing and sampling ofM W-5, and hope to see
that work done in the morning on Wednesday.

5.0 RECOMMENDATIONS (March 10,2003 Report)
Based upon the results of the first two years of monitoring of the site twice annually and
the summary of those results provided in Section 4-0 of this report, ATC would like to
propose the following modifications to the MOM? monitoring and analytical program on
behalf of Intier Automotive Seating of America, Inc, and (Tntier).
• That groundwater and surface water sampling activities at the site go to annual
monitoring as proposed in the MOMP. The proposed sampling would occur
between April and June of each calendar year;
• That the analytical testing program be modified to incorporate the following
changes:
The Target Analyte List — Inorganics (Both Total and Dissolved) be modified to
analyze only the following:
Aluminum, Chromium, Cobalt, Iron, Manganese and Sodium
Chloride
Ammonia Nitrogen
Chemical Oxygen Demand
• No changes are proposed to the Target Compound List —Volatile Organic
Compounds (TCL-VOCs) or any of the field sampling procedures or parameters.
~ That the full Analyte List as proposed in Appendix A of the MOMP be run every
five (5) years or when significant changes in the previously noted parameters
suggest that expansion of the testing program is warranted,
> That the groundwater use survey be conducted on an annual basis' as defined in
the MOMP,
That the Riverbank Slope be inspected annually at the time of the groundwater
and surface water sampling starting in the Spring of 2003. Samples from seepage
in the Riverbank Slope area will be obtained, if necessary, as described in the
MOMP.
That the results of site monitoring be provided to EPA Region 7 annually by the
end of the calendar year. •

Monitoring Program Modification Justification — Elements/Metals
The request for reduction of the annual Element/Metals analytical program was based
upon the following observations from, the first two years of site monitoring.
• The element/metal analytes could be divided into the following four categories:
Category I - Those having concentrations less than or very close to the
method detection limit (MDL);
Category II - Those h aving concentrations greater than the MDL but less
than established Maximum Contaminant Levels (MCLs) or recommended
allowable limits for drinking water;
Category HI ~ Those having concentrations significantly higher than
drinking water standards; and
Category IV - Those having elevated concentrations but no established
water quality standards.

RE: Red Oak Landfill Superfund Site, Red Oak, Iowa
The U.S. Environmental Protection Agency (EPA) has received your request, presented in
the Red Oak Landfill Monitoring and Maintenance Report submitted March. 7,2003, by ATO
Associates, to modify several items in the Monitoring and Maintenance Plan (MOMP) following
the completion of two years of monitoring and maintenance. The EPA has also reviewed the
March. 7 report and has no comments to offer on it.
Regarding the request to change the MOMP, the EPA has the following comments:
1, You requested that sampling activities be on an "annual frequency after the two year period, as
agreed to-in the MOMP. Yon stated that the annual sampling would occur between April and
June of each year. The BP A agrees with this change in sampling frequency and with the*' •
proposed sampling date.
2. You requested that the Target Anaiyte List for Inorganics be reduced to only include
aluminum, chromium, cobalt, iron, manganese, sodium, chloride, ammonia and chemical oxygen
demand. This would eliminate sampling and analysis for antimony, arsenic, barium, beryllium,
cadmium, calcium, copper, lead, magnesium, mercury, nickel, potassium, selenium, silver,
thallium, vanadium, zinc, cyanide, total organic halogens and phenol. Based on our review of
the monitoring results over the last two years, the EPA agrees to eliminate antimony, beryllium,
calcium, copper, lead, magnesium, mercury, potassium, silver, thallium, vanadium, cyanide, and
phenols. Because of recent sample results near or in exceedance of action levels, the EPA does
RECYCLE^
p*f sacwtwks Fa e*s

not agree to eliminate the inorganics listed below; these should be included in the annual
sampling program along with the elements yon proposed to include,
Arsenic Barium Cadmium Nickel Selenium Zinc
Total Organic Halogens
3: You proposed that the full analyte list in Appendix A of the MOMP be run every five years,
or when significant changes in sampling results suggest that expansion of the testing program is
warranted, The EPA agrees with your proposal,
4. You proposed that the groundwater use survey be conducted annually. The EPA agrees,
5. You proposed that the Riverbank Slope be inspected annually at the time of sampling. The
EPA agrees with your proposal
6. You requested that the results of site monitoring be provided to EPA annually by the end of
the calendar year. The EPA would prefer to maintain the schedule in the approved MOMP,,
which requires report submittal on the anniversary of EPA Certification, or November 19 of each
year. The EPA believes this time frame would be feasible based on the proposed sampling dates,
and would avoid the busy holiday season ' — » —
Please proceed with the 2003 annual sampling on the schedule rioted. Also, we would
request revised pages of the MOMP for the changes noted above, particularly for items 2, 3, and
6. If you have any questions, please call me at 913-551-7654.

5.0 RECOMMENDATIONS
Based upon observations made over the past three years of site monitoring, ATC would
like to propose the following modification to the MOMP monitoring and analytical
program on behalf of Intier Automotive Seating of America, Inc. (Ihtier),
• That consideration be given to elimination of the requirement for up- and downstream
surface water sampling of the East Nishnabotna River,
This proposal is based upon the following observations and opinions:
• Existing Surface-Water Data
Over the monitored period there has been no evidence of volatile organic compound
(VOC) impacts to the surface water.
Several occurrences have been observed where greater elemental concentrations were
measured in the downstream sample location SW01 compared with the upstream sample,
SW02, and duplicate, SW03, These have been most notable in the concentrations of
Aluminum, Iron, and Sodium, but have tended to be less pronounced or absent in the
dissolved fraction sample suggesting that sediment load in the samples could be
influencing this 'increase.' These differences do not appear to be related to seasonal
variations. Hence, in our opinion these occurrences do not suggest that the river is being
impacted by leachate seepage from the former landfill.
• Groundwater Data
The level of flow in the East Nishnabotna, even in the past few years where flow
has been below average, creates significant dilution of any groundwater discharge
contributing to the river. As discussed in section 4.1.4, the concentrations of
contaminants of concern, where detected in the groundwater monitoring wells, are
generally low:
¦ detections of a limited number of VOCs at low concentrations are
observed in GW05 and, on one sampling event, one VOC at GW02;
concentrations are typically below the MCL.
¦ Metal concentrations are also relatively low in the groundwater, although
some do exceed MCLs.
Hence, in our opinion, with such low contaminant concentrations in the groundwater; the
limited quantity of groundwater discharge along the river and the absence of any leachate
seepage observed from the riverbank slope, any leachate from the landfill entering the
groundwater will be significantly diluted upon discharge to the river and surface water
sampling at any location downstream of the source will be unlikely to identify the
impact(s) if any.

For these reasons, we propose that the annual stream sampling be discontinued, unless
significant concentration increases for the contaminants of concern are observed in the
site monitoring wells or significant leaehate discharge is identified from the riverbank
slope during site monitoring or maintenance activities.

Deaf Ms, Haynes:
Re: Red Oak Landfill Superfund Site, Red Oak, Iowa
The TJ.-S, Environmental Protection Agency (BPA) has received your request, presented in
the Red Oak Landfill Monitoring and Maintenance Report submitted November 21, 2003, by
ATC Associates, to modify surface-water sampling in the Monitoring and Maintenance Plan
(MOMP) following the completion of three years of monitoring and maintenance. The EPA has
also reviewed the November 21 report and has no comments to offer on it.
Yon requested that EPA consider discontinuation of the surface water sampling activities
upstream" and downstream of the site because of the low levels of contaminants found in previous
surface water and groundwater samples, and based on the absence of leachate seepage and the
limited quantity of groundwater discharge along the river. On page 43 of the report, it is
proposed that said sampling be discontinued, "unless significant concentration increases for the
contaminants of concern are observed in the site monitoring wells or significant leachate
discharge is identified from-the riverbank slope during site monitoring or maintenance activities",
The EPA agrees that the surface water sampling to date has not indicated a problem of
contamination of the river. We agree to the proposal to discontinue the annual surface water
sampling, unless significant concentration increases for the contaminants of concern are observed
in the site monitoring wells or significant leachate discharge is identified from the riverbank
slope during site monitoring or maintenance activities. Please submit revised pages of the
MOMP for this change; these changes should make it clear that the underlined contingency
should be addressed in the annual Monitoring and Maintenance Reports each year, hi addition,
we would still require the surface water sampling to be conducted once every five years, on the
same schedule as the full analyte sampling ha the spring or summer of 2007.

Subject: Analytical and Sampling Frequency Modification Proposal
Red Oak Landfill Superfund Site
Red Oak, Iowa
Dear Ms. Brodie:
On behalf of Magna International, Cardno ATC has prepared the following proposal for
consideration by U.S. Environmental Protection Agency (EPA) Region 7 regarding reduction of
monitored parameters and monitoring well sampling frequency at the Red Oak Landfill
Superfund site in Red Oak, Montgomery County, Iowa.
Specifically, Cardno ATC is requesting that consideration be given to removal of Ammonia
Nitrogen, Chloride, Chemical Oxygen Demand (COD) and Total Organic Halogens (TOX) from
the monitoring program. In addition, we are requesting that monitoring well sampling at the
landfill be conducted on a biennial basis (every two years) rather than annually starting with
2014 and in subsequent even number years. These requests are consistent with
recommendations presented in the document Third Five-Year Review Report, Red Oak City
Landfill, Red Oak, Iowa, dated July 2012. The rationale for these requests as well as reviews of
historical chemical analyses and their significance follows.
As of the date of this submittal, the project site has been monitored semi annually in 2001 and
2002, and annually from 2003 through 2013, a total of fifteen (15) monitoring events over a
thirteen (13) year period. Over the monitored period, reductions of some of the metals analytes
have been approved by EPA Region 7. These reductions were based upon the analytical results
obtained. As a result, the Analyte Short List of parameters is being analyzed annually and the
Full Analyte List is being analyzed every five years when the year is divisible by five (5).
It should be noted that milligrams-per liter (mg/L) and micrograms-per-liter (|jg/L) are both
utilized in the following discussion. Milligrams-per-liter, equal to 1,000 |jg/L, is generally utilized
in referencing regulatory values and micrograms-per-liter, are used in discussion of the analytical
results.

Ammonia Nitrogen
Ammonia Nitrogen is an inorganic, dissolved form of nitrogen found in water that is the preferred form for algae and
plant growth. Ammonia is the most reduced form of nitrogen and is found in water where dissolved oxygen is
absent or reduced. In the presence of readily available dissolved oxygen, ammonia is quickly oxidized to nitrate by
bacteria. Other bacteria generate ammonia in the process of decomposing dead plant and animal matter. The
toxicity of ammonia to aquatic life increases with increased pH and temperature. High concentrations of ammonia
can stimulate excessive aquatic production and is an indicator of the presence of pollutants in the water. Sources
of ammonia in water include fertilizers, human and animal wastes and byproducts of industrial manufacturing
processes.
Over the period the landfill has been monitored, ammonia nitrogen concentrations in surface water samples,
seep/spring samples and monitoring wells GW01, GW02, and GW04 have generally ranged from <100 to 210 |jg/L.
There was one instance where surface water sample SS02 and duplicate SS03 reported concentrations of 300 to
400 |jg/L. Within monitoring well GW05 and duplicate sample GW06, ammonia nitrogen concentrations have
ranged from <100 to 600 |jg/L with all the analyses but two being in the <100 to 300 |jg/L range. Two results were
reported at 590 and 600 |jg/L. The highest concentrations of ammonia nitrogen have been in monitoring well
GW03 where reported concentrations have ranged from 100 to 1,020 |jg/L (1.020 mg/L) with approximately two-
thirds of the values being in the 360 to 610 |jg/L range.
There are no ammonia nitrogen action levels for the site based on a review of applicable surface water or
groundwater regulations and literature. Under the provisions for discharge of wastewater from landfills listed in 40
CFR Part 445, Subpart B - RCRA Subtitle D Non-Hazardous Waste Landfill, which are more stringent than those
for hazardous waste landfills, discharges of Ammonia (as N) are subject to the following effluent limitations:
Maximum Daily - 10 mg/L; Maximum Monthly Average - 4.9 mg/L. The maximum value for ammonia nitrogen
reported for the site is 1.02 mg/L. Based on this comparison, concentrations of ammonia nitrogen present at the
site do not appear to represent a concern to the public or the environment.
Chemical Oxygen Demand (COD)
Natural organic detritus and organic waste from waste water treatment, human and animal waste, and agricultural
and urban runoff act as food sources for water-borne bacteria. These bacteria decompose the organic matter using
dissolved oxygen in the water, which reduces the quantity of dissolved oxygen available for aquatic life.
Biochemical Oxygen Demand (BOD) is a measure of the amount of oxygen the bacteria will consume in the
decomposition of organic matter under aerobic conditions. COD does not differentiate between biologically
available and inert organic matter and is a measure of the quantity of oxygen required to oxidize all organic material
into carbon dioxide and water. COD values are always greater than BOD values.
COD concentrations in the surface water samples, seep/spring samples and monitoring wells GW01, GW02 and
GW04 have been less than 40,000 |jg/L with the exception of one sample each in GW01 and GW02 and two
samples in GW04. Values greater than 40,000 |jg/L at these locations ranged from 46,000 to 62,300 |jg/L. COD
concentrations in GW03, GW05 and GW06 range from <10,000 to 144,000 |jg/L with 26 samples (57.8%)
exceeding 40,000 |jg/L, 20 samples (44.4%) exceeding 50,000 |jg/L and five samples (11.1%) greater than
100,000 Mg/L
There are no established action levels for COD at the site based upon a review of surface water and groundwater
regulations and literature. Under the provisions for discharge of wastewater from landfills listed in 40 CFR Part
445, Subpart B - RCRA Subtitle D Non-Hazardous Waste Landfill, discharges of BOD are subject to the following
www.cardnoatc.com
-------
U.S. Environmental Protection Agency, Region VII
3
ATC
effluent limitations: Maximum Daily - 140 mg/L; Maximum Monthly Average - 37 mg/L. Effluent Limitations for
BOD5 listed in Subpart A - RCRA Subtitle C Hazardous Waste Landfill are: Maximum Daily - 220 mg/L; Maximum
Monthly Average - 56 mg/L. The maximum value for COD reported for the site is 144 mg/L. Approximately 39% of
the COD values listed for the monitoring wells exceed 37 mg/L and approximately 24% of the COD values exceed
the 56 mg/L limitation. Based on comparison of the reported COD values with the identified effluent limitations and
that COD values are typically greater than BOD values, COD concentrations do not appear to be elevated nor
significant to evaluation of contaminant conditions and trends at the subject site. It should be noted that COD
values reported in the surface water and the seep/spring samples, those most appropriate to direct evaluation of
identified exposure pathways at the landfill site, have all been less than 34 mg/L.
With a single exception, reported chloride concentrations in the surface water samples and monitoring wells GW01,
GW03 and GW04 have been below 25,000 |jg/L. Chloride concentrations reported in seep/spring samples have
generally been reported in the 27,000 to 34,600 |jg/L range with the exception of a single sample reported at
123,000 |jg/L. Historically, chloride concentrations in GW02 were reported in the range of 30,000 to 55,000 |jg/L.
The highest chloride concentrations have been reported in monitoring well GW05 and duplicate well GW06 where
concentrations range from 86,000 to 300,000 |jg/L with approximately 23% of the reported values in these wells
exceeding 230,000 |jg/L.
The U.S. Army Corps of Engineers in the course of preparing the 2012 Five-year review report identified the
surface water action level for Chloride at the site as 230,000 |jg/L. Secondary Drinking Water Regulations limit
chloride concentrations to 250 mg/L (250,000jjg/L). The Iowa Department of Natural Resources has recently
revised surface water quality criteria regarding Chloride. Using statewide background values for hardness and
sulfate, the acute criteria value for chloride is 629 mg/L (629,000 jjg/L) and the chronic criteria value is 389 mg/L
(389,000 |jg/L). Comparison of these values with the monitoring results indicates isolated results in GW05 and
GW06 marginally exceed the secondary drinking water value and the action level for surface water.
Total Organic Halogens (TOX)
The presence of organic halogens is utilized as an indicator of the presence and degree of contamination in
groundwater because naturally occurring organic halides are very limited and their occurrence is a strong indication
of the presence of man-made contamination.
TOX results over the monitored period indicate the majority of the results are less than 50 |jg/L at the sampled
locations. At monitoring well locations GW01, GW02, GW03 and GW04, with the exception of six results, TOX
values have been 50 |jg/L or less. Values exceeding 50 |jg/L ranged from 60 to 80 |jg/L. TOX concentrations
reported in GW05 and duplicate GW06 ranged from <10 to 300 |jg/L with eleven (36.7%) of the values exceeding
100 |jg/L. TOX concentrations in the surface water samples ranged from less than 10 to 60 |jg/L with only two
values exceeding 30 |jg/L. Seep/spring samples have contained <10 to 138 |jg/L of TOX with only the most recent
sample exceeding 50 |jg/L.
There are no action levels for TOX applicable to the site based upon review of applicable surface water and
groundwater regulations and literature. TOX was reported at concentrations of 57 to 271 |jg/L in the two field
blanks collected during the 2013 monitoring event, suggesting the TOX concentrations reported from the landfill site
are not significantly elevated.

Summarizing, from the preceding review, the Ammonia Nitrogen, Chloride, COD and TOX analyses are indicators
of general groundwater and surface water quality. The majority of analytical results for these parameters obtained
to date do not suggest that values are at elevated concentrations which would be indicative of poor general water
quality or that water quality detrimental to the environment or to human health is present. In 13 years of sampling
and analysis, the results generally are not showing discernible trends toward increasing significantly and in the
absence of established regulatory target levels, the results can generally only be utilized in relative comparisons to
other samples at the site. Over the monitored period, only the chloride concentration in monitoring well GW04, and
possibly GW01, has shown an increasing concentration trend overtime.
Based on these observations it is proposed that these parameters be removed from the monitoring program.
Sampling Frequency Reduction
Based upon the results of thirteen (13) years of monitoring there are few, if any, readily identifiable increasing
trends with regard to any of the monitored parameters including total and dissolved metals, volatile organic
compounds, phenols, chloride, Chemical Oxygen Demand (COD), Ammonia Nitrogen, and Total Organic Halogens
(TOX). Considering these results, it is suggested that consideration be given to reducing the monitoring frequency
of the monitoring wells at the site. Justification for this proposal follows.
It is proposed that monitoring well sampling at the landfill be conducted on a biennial basis (every two years) rather
than annually starting with 2014 and in subsequent even number years. It is proposed that this modification will
provide adequate monitoring of water quality at the site and provide equivalent data for use in the Five-Year Review
process.
The most recent Five-Year Review, completed in 2012 is utilized as an example. This report utilized data obtained
during and prior to 2011 in its analysis of site conditions. With regard to data for the Full Analyte List of metals,
cyanide and phenols, these parameters were last sampled in 2010, two years prior to the report submittal.
The proposed monitoring schedule, monitored analytes and Five-Year Review schedule is summarized by the
following table.

The 2030 monitoring event will represent 30 years of monitoring for the former landfill site.
Monitoring events identified as Full Analyte List will continue to analyze the Full Analyte List of total and dissolved
metals, VOCs, cyanide and phenols and include sampling of the site monitoring wells, surface water up and
downstream of the landfill site, any seeps or springs and required duplicates. The preceding assumes that
Ammonia Nitrogen, Chloride, COD and TOX will be removed from the analytical program.
The provision for an increase in monitoring frequency or in the monitored parameters consistent with current
sampling procedures remains should either analytical data or site observations suggest that such an increase is
prudent to evaluate contaminant conditions at the site, the effectiveness of the remedy or potential impacts to the
environment.
At the present time, it is intended that the following monitoring activities will continue on an annual basis in addition
to the annual maintenance activities conducted by the City of Red Oak.
• The Riverbank Slope's condition will be observed in the spring and the fall at a minimum and its condition
will be documented.
• Seep/spring location SS-01 will be sampled and analyzed annually for the Analyte Short List of parameters
unless it is a year in which the Full Analyte List is to be analyzed.

• The inclinometer will continue to be gauged annually.
• An annual review of apparent groundwater use within a two-mile radius of the site will be conducted and
documented.
• An annual Monitoring Operations and Maintenance Report will be prepared.
EPA Region 7's consideration of the preceding proposals is appreciated. Should Magna receive no comment on
the suggested changes by April 1, 2014, it will be assumed that the EPA approves of the proposal and the new
sampling program and frequency will be implemented. Please contact Mr. Avin Duggal, Remediation Manager at

Analytical Summary - Elements and Metals
Red Oak Landfill Superfund Site, Red Oak, Iowa
Calendar Years 2001 Through 2019
All values reported in the following tables are reported in j^ig/L which is equivalent to parts-per-billion.
Indicated "Action Levels" for groundwater and surface water were obtained from Tables 2 and 3 of the Third Five-Year Review Report, Red Oak
City Landfill, Red Oak, Iowa, prepared by the U.S. Army Corps of Engineers on behalf of U.S. EPA Region 7, dated July 2012.
Values that are presented in Bold type in the tables exceed the analytical method detection limit. Cells which are shaded represent the maximum
concentration reported for each parameter and sample location. Cells with amber shading are the maximum values reported for the site. It should
be noted that monitoring well GW06, surface water SW03, and seep sample SS-02 are duplicate QA/QC samples. Since duplicate sample locations
can change, the results for GW06 should not be utilized directly for comparison purposes. However, the surface water and seep samples are obtained
from the same mediums, the river and surface seep, and the results from these samples can be directly interpreted for evaluation of water quality.
For comparison purposes, GW06 is a duplicate of GW05 unless otherwise indicated. The single exception was in 2005 when GW06 was a duplicate
of GW03. Surface water sample SW03 has consistently been a duplicate of SW02 (the upstream sample) throughout the monitored period.
Graphs of the monitoring well data are provided for total and dissolved concentrations of: Aluminum, Arsenic, Barium, Cobalt, Iron, Manganese,
Nickel, Selenium, Sodium and Zinc. Two parameters have a wide range of reported concentrations, total Aluminum, and total Chromium. For these
parameters, two graphs are provided, one presented full scale and a second at reduced scale to depict trends in wells having lower contaminant
concentrations. The attached graphs of the analytical data do not include data from monitoring well location GW06, which is a duplicate sample.
For clarity, the graphs depict the maximum value for the sampled well or its duplicate.
For comparison purposes, seep sampling data has been added to the following tables. Typically the seep samples have not been collected at the same
time that the monitoring wells and surface water samples have been obtained. Subsequently, the referenced time of year may not be accurate. It
should also be noted that data from the October 30, 2007 seep sample is not included in the table.
* Summer 2004 metals data. Data from monitoring well locations GW02 and GW05 were apparently reversed. Corrected data is presented in the
affected tables.
