Preface

The U.S. Environmental Protection Agency (EPA) is conducting a study of the potential impacts of
hydraulic fracturing for oil and gas on drinking water resources. This study was initiated in Fiscal Year
2010 when Congress urged the EPA to examine the relationship between hydraulic fracturing and
drinking water resources in the United States. In response, EPA developed a research plan (Plan to
Study the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources) that was reviewed by
the Agency's Science Advisory Board (SAB) and issued in 2011. A progress report on the study (Study of
the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources: Progress Report), detailing
the EPA's research approaches and next steps, was released in late 2012 and was followed by a
consultation with individual experts convened under the auspices of the SAB.

The EPA's study includes the development of several research projects, extensive review of the
literature and technical  input from state, industry, and non-governmental organizations as well as the
public and other stakeholders. A series of technical roundtables and in-depth technical workshops were
held to help address specific research questions and to inform the work of the study. The study is
designed to address research questions posed for each stage of the hydraulic fracturing water cycle:

    •   Water Acquisition: What are the possible impacts of large volume water withdrawals
        from  ground and surface waters on drinking water resources?

    •   Chemical Mixing: What are the possible impacts of surface spills of hydraulic fracturing fluid
        on or near well pads on drinking water resources?

    •   Well Injection: What are the possible impacts of the injection and fracturing process on
        drinking water resources?

    •   Flowback and Produced Water: What are the possible impacts of surface spills of flowback
        and produced water on or near well pads on drinking water resources?

    •   Wastewater Treatment  and  Waste Disposal: What are the possible impacts of inadequate
        treatment of hydraulic fracturing wastewaters on drinking water resources?

This report, Retrospective Case Study in Killdeer, North Dakota, is the product of one of the research
projects conducted as part of the EPA's study. It has undergone independent, external peer review in
accordance with Agency policy and all of the peer review comments received were considered in the
report's development.

The EPA's study will contribute to the understanding of the potential impacts of hydraulic fracturing
activities for oil and gas on drinking water resources and the factors that may influence those impacts.
The study will help facilitate and inform dialogue among interested stakeholders, including Congress,
other Federal agencies,  states, tribal government, the international community, industry, non-
governmental organizations, academia, and the general public.

Executive Summary
In December 2009, Congress urged the U.S. Environmental Protection Agency (EPA) to conduct a study
to better understand the relationship between hydraulic fracturing for oil and gas on drinking water
resources. This report provides the results of one of five retrospective case studies conducted as a
component of EPA's national study on potential impacts of hydraulic fracturing on drinking water
resources (US EPA, 2011a, 2011b).  Retrospective case studies focused on investigating reported
instances of drinking water contamination in areas where hydraulic fracturing has already occurred.
This report describes the retrospective case study in Dunn County, North Dakota, conducted near
Killdeer, North Dakota. The Killdeer study area is the location of historical oil and gas production, with
current unconventional oil and gas production occurring in the late Devonian/early Mississippian-aged
Bakken Shale. A known blowout occurred at this site, the Franchuk 44-20 SHW well (Franchuk well)
during the hydraulic fracturing process to complete the well. The blowout occurred during the fifth
stage of a 23-stage hydraulic fracture. This resulted in a release of hydraulic fracturing fluids, oil, and
flowback water onto the  land surface and possibly into the Killdeer aquifer. The release occurred when
an inner string of casing burst due to over-pressurization during the hydraulic fracturing process (Jacob,
2011).

Water quality samples were collected from three domestic wells, nine monitoring wells, two supply
wells, one municipal well, and one state well during three rounds in July 2011, October 2011, and
October 2012. All wells at the Killdeer site, except NDGW09, were screened in the Killdeer aquifer.
Regarding the exception, information provided to EPA suggested that this deep monitoring well was
screened in the Killdeer aquifer; however, the presence of lignite in the well log suggests that it may also
be screened, all or partially, in the underlying Sentinel Butte aquifer.

The geochemistry of water samples was investigated by analyzing major ions, trace metals,
methane/ethane gas concentrations,  volatile organic compounds (VOCs), semi-volatile organic
compounds (SVOCs), glycol ethers, diesel- and gasoline-range organics (DRO and GRO), low-molecular-
weight acids, and selected stable isotopes (618OH20, 62HH20, and 87Sr/86Sr). Major ion data collected from
this study were compared with historical water quality data retrieved from the literature and national
water quality databases,  including the U. S. Geological Survey (USGS) National Water Information
System (NWIS; USGS, 2013), North Dakota State  Water Commission (NDWC) databases (NDWC, 2013),
and the report Ground Water Basic Data for Dunn Co., North Dakota (Klausing 1976). These data
sources provided water quality data for samples  collected prior to major development of the Bakken
Shale play and provided an initial screening for potential ground  water contamination.  Statistical
comparisons (analysis of  variance [ANOVA] and Kruskal-Wallis tests) were made between the data
collected from this study and the historical data.  In order to help determine whether hydraulic
fracturing or processes related to hydraulic fracturing were the cause or one of the causes of alleged
impacts on water quality, other potential contaminant sources were identified by conducting detailed
environmental record searches.

The initial examination of major anions and cations indicated that two of the study wells, NDGW07 and
NDGW08, showed statistically significant differences in parameters such as chloride, calcium,
magnesium, sodium, and strontium, compared to other study wells. No other study wells showed
differences in chloride, calcium, magnesium, sodium, and strontium, with the exception of NDGW06 in
the October 2012 sampling round when compared to the other study wells. In the October 2012

sampling round, the chloride concentration in the NDGW06 sample was elevated, however it was
determined that the chloride concentration in the October 2012 NDGW06 sample was an outlier. All
other parameters for the October 2012 NDGW06 sample were not outliers based on the Dixon Q-test
performed  (Dean and Dixon, 1951).  Using the data collected during this study, it cannot be determined
whether the October 2012 NDGW06 chloride concentration was an anomalous data point or an
indication of an additional impacted well.

All study wells with the exceptions of NDGW07, NDGW08, and NDGW09 (NDGW09 was screened partly
or completely in the Sentinel Butte Aquifer) were compared with the historical data from the NWIS,
NDWC, and Klausing (1976) data sources for the Killdeer aquifer. NDGW09 was not used in this
comparison because well logs indicated that it was at least partially screened in the Sentinel Butte
aquifer and, therefore, would not be comparable to the Killdeer aquifer. NDGW07 and NDGW08 were
not compared with historical data because the initial data screening indicated that these wells had
different water quality than the other study wells in the study. The comparison to historical data was
performed on historical data within a 3-mile radius of the Franchuk well to ensure that the comparison
was reflective of the local Killdeer aquifer chemistry. The comparison of these study wells with the
historical data showed that there were no statistical differences and that these study wells were
unimpacted, even with inclusion of the October 2012 NDGW06 sample.

Dissolved gases were compared with the results of a report by the  state of North Dakota (Anderson et
al., 2010) for field screening for shallow gas. Methane was detected in 24% of the total samples, with a
maximum concentration of 0.0253 mg/L These observed concentrations were consistent with
background methane concentrations of 0.0149 to 0.3978 mg/L. There were no observed impacts on
drinking water quality from methane.

There were limited detections of other organic compounds in the study wells during the study. Thirty-
eight VOCs  were analyzed for during the study, and at least one was detected in 15% of the samples.
The VOCs detected were acetone, toluene, m+p-xylene, o-xylene, 1,2,4-trimethylbenzene, and 1,2,3-
trimethylbenzene (2% of the detections); benzene (7% of the detections); and tert-butyl alcohol (TBA)
(15% of the detections).  Glycols were not detected in the study wells during the study. The detection
frequency for low-molecular-weight acids was 8%, and the detections were for formate (10% of
detections) and acetate (31% of detections).  Finally, 84 SVOCs were analyzed for during the study, and
at least one was detected in 17% of the samples. The SVOCs detected during the study were 2-
butoxyethanol, dimethyl phthalate (2% of the detections), bis-(2-ethylhexyl) phthalate (17% of the
detections), and bis-(2-ethylhexyl) adipate (34% of the detections). In most cases, with the exception of
tert-butyl alcohol (TBA), the detected organic compounds reasonably could be related back to sources
that were not related to the Franchuk well blowout. These sources included vehicular traffic, generators
used to power well pumps, flaring of methane from the pad's production wells, and polyvinyl chloride
(PVC) cement that was used to repair NDGW10 the day prior to sampling.

TBA was consistently detected in NDGW07 and  NDGW08 but was not detected in any of the other study
wells. No historical data were found for TBA in the historical literature, so comparisons with the results
from this study could not be made. Based on the analysis of other  potential sources of contamination, it
was determined that the only potential sources of TBA were from gasoline spills, leaking underground
storage tanks (USTs), and hydraulic fracturing fluids. If derived from these sources, the TBA would have
to be a degradation product of methyl tert-butyl ether (MTBE) (from gasoline) or tert-butyl

hydroperoxide (from hydraulic fracturing fluid). However, MTBE or other compounds expected to be
associated with MTBE were not detected, and the remaining possible origin of TBA would be the tert-
butyl hydroperoxide used in the hydraulic fracturing of the Franchuk well.  Based on the data in this
study, the TBA observed in NDGW07 and NDGW08 was consistent with the blowout of the Franchuk
well being the source of the TBA.

An initial hydrological investigation was conducted at the Killdeer case study site. The investigation
identified potentially significant temporal fluctuations in the hydraulic gradient beneath the pad.
However, there was always a  southerly component to the ground water flow.  The southerly component
of the flow is important, because it eliminates one potential source, road salt, for the observed changes
in water quality (elevated chloride concentrations) to NDGW07 and NDGW08. The potential source,
road salt, was applied to the highway adjacent to the southern edge of the study site.  For this to be a
source of contamination, the  ground water flow would have to  have a northerly component, which was
never observed.

The time trends for various parameters in the study wells were  also analyzed.  The concentrations of
various inorganic parameters  did not vary over time in the unimpacted wells. However, in NDGW07 and
NDGW08, the trends for inorganic parameters and for TBA were consistent with contaminant transport
through these wells. Furthermore, the time trend analysis was  consistent with the blowout at the
Franchuk well being the potential source of contamination, particularly because NDGW07 and NDGW08
were downgradient of the Franchuk well.

The analysis of data from NDGW07 and NDGW08 indicates that the main impact on water quality was
from briny water and TBA mixing with Killdeer aquifer water in these wells. In all cases, the
fingerprinting techniques used confirmed that the impacts on NDGW07 and NDGW08 were likely from
deep formation brines underlying the Killdeer study location. Based on the available deep formation
brine data and the use of sodium to lithium (Na/Li) ratios, chloride to iodide (Cl/l) ratios, and isotopic
analysis, it was determined that the brine had a Madison Formation-like signature and analysis to
determine the potential source of the observed impacts was undertaken.  Other sources of impacts on
drinking water quality, such as nearby oil and gas activities, land use practices, leaking USTs, and
industrial activities, are unlikely.  This is because of the lack of detections of organic compounds and the
lack of any signature of any source of contamination in the other monitoring wells at this pad.  Based on
the data in this study, the briny water observed in NDGW07 and NDGW08 was consistent with the
blowout of the Franchuk well  being the source of the brine.

However, analysis of the data indicated that brine characteristic of the Madison formation rather than
the Bakken formation was the source of the impact. Additional literature review indicates that out-of-
zone fracturing, or propagation of fractures outside the production zone into adjacent formations, is a
common problem in Bakken formation wells. This literature indicates that in a high percentage of
Bakken wells that have out-of-zone fracturing also have Madison formation brine signatures. The
finding of a Madison formation brine source of impact on NDGW07 and NDGW08 is consistent  with
what was reported  in the literature.

The results for several study samples, as well as the historical data, indicated that sulfate exceeded the
secondary maximum contaminant level (SMCL) overtime. Analysis of the sulfate data and information
on the geology of Dunn County indicate that the sulfate concentration in the Killdeer aquifer is  from

naturally occurring sources such as gypsum and selenite in the soils. It is unlikely that any impacts from
anthropogenic activities would cause the high sulfate concentrations observed in the Killdeer aquifer.

Based on the data analysis performed for the Killdeer case study, the observed impacts on NDGW07 and
NDGW08 are consistent with the blowout that occurred at the Franchuk 44-20 SWH well being the
source of the impact.

Key observations or findings from this study are listed below.

    •   With the exception of TBA (detected in two wells), all VOC compounds (detected in three wells)
       and SVOC compounds (detected in five wells) could be related to a potential  source other than
       hydraulic fracturing. No glycols were detected in the study wells during the study.

    •   Methane was detected in 24% of the study samples, with a maximum observed concentration of
       0.0253  mg/L   Methane concentrations observed during the  study  are consistent  with
       background  methane concentrations in the Killdeer aquifer (0.0149 to 0.3978 mg/L).

    •   For sulfate,  38%  of the study samples exceeded  the  secondary maximum contaminant level
       (SMCL). The sulfate concentrations in the Killdeer aquifer are consistent with naturally occurring
       sources such as gypsum and selenite in the soils of Dunn County  and are consistent with the
       historical data.

    •   With the exception of three wells (two impacted wells and a well screened or partially screened
       in  another aquifer), the results from the  study wells were not significantly different than the
       historical data from the Killdeer aquifer and were considered unimpacted wells.

    •   The study identified two  impacted  monitoring wells that had water quality different from the
       other study wells and historical data.

    •   TBA was consistently detected in the two impacted monitoring wells, but not in the unimpacted
       wells.  TBA concentrations were consistent with the degradation of tert-butyl hydroperoxide, a
       component used in the hydraulic fracturing fluid at the time of the blowout.

    •   The only potential source consistent with  the conditions observed  in the two impacted wells is
       the blow out that occurred at the Franchuk 44-20 SWH well.

1. Introduction
Recent advances in drilling technologies (horizontal drilling) and well stimulation (hydraulic fracturing)
have resulted in large-scale development of vast, unconventional reserves of oil and gas across a wide
range of geographic regions and geologic formations in the United States. These reserves are
considered unconventional because they are bound up in low-permeability reservoirs such as shale,
tight sands, limestone, and coal beds, and recovery of these reserves was previously uneconomical.
While some of this new development is occurring in areas with mature oil and gas fields, vast areas with
very little or no previous oil and gas development also are now being developed. As a result, there are
rising concerns over potential impacts on human health and the environment, especially with regard to
potential effects on drinking water sources. Environmental concerns include the potential for
contamination of shallow ground water by stray gases (methane), formation waters (brines), and
fracturing chemicals associated with unconventional  gas development.

Congress urged EPA in December 2009 to study the relationship between hydraulic fracturing and
drinking water. The study was to be conducted using a credible approach that relied on the best
available science as well as independent sources of information, and through a transparent, peer-
reviewed process that would ensure the validity and  accuracy of the data. EPA consulted with other
federal agencies and appropriate state and interstate regulatory agencies in carrying out the study (US
EPA, 2010a).  In February 2011, EPA issued the Draft  Plan to Study the Potential Impacts of Hydraulic
Fracturing on Drinking Water Resources (US EPA, 2011a). The final Plan to Study the Potential Impacts
of Hydraulic Fracturing on Drinking Water Resources  was released in November 2011 (US EPA, 2011b).

In 2011, EPA began to research the potential impacts of hydraulic fracturing on drinking water
resources, if any, and to identify the driving factors that could affect the severity and frequency of any
such impacts. EPA scientists focused primarily on hydraulic fracturing of shale formations, with some
study of other oil- and gas-producing formations, including coal beds.  EPA designed the scope of the
research around five stages of the hydraulic fracturing water cycle (US EPA, 2012).  Each stage of the
cycle is associated with a primary research question:

    •  Water acquisition: What  are the  potential  impacts of large-volume water withdrawals from
       ground water and surface waters on drinking water resources?

    •  Chemical mixing: What are the  potential impacts of hydraulic fracturing fluid surface spills on or
       near well pads on drinking water resources?

    •  Well  injection: What  are the  potential impacts of the injection and  fracturing process on
       drinking water resources?

    •  Flowback and produced water:  What are the potential impacts of flowback and produced  water
       (collectively referred to as "hydraulic fracturing wastewater") surface spills on or near well pads
       on drinking water resources?

    •  Wastewater treatment and waste disposal:  What are the  potential impacts  of inadequate
       treatment of  hydraulic fracturing wastewater on drinking water resources?

Retrospective Case Study in Killdeer, North Dakota                                                 May 2015


Prior to release of the  study plan, EPA invited the public to nominate specific regions of the United
States for inclusion as  potential sites for case studies. The plan identified 41 potential retrospective case
study sites. The retrospective case studies were to focus on investigating reported instances of drinking
water resource contamination in areas where hydraulic fracturing has already occurred and were
intended to inform several of the primary research questions related to chemical mixing, well injection,
and flowback and produced water.  Of the 41 sites nominated during the stakeholder process, EPA
selected five sites across the United States at which to conduct retrospective case studies. The sites
were deemed illustrative of the types of problems that were reported to EPA during stakeholder
meetings held in 2010 and 2011.  Additional information on site selection can be found in the Study Plan
(US EPA 2012). EPA's plan for the retrospective case studies was to make a determination on the
presence and extent of drinking water resource contamination as well as whether hydraulic fracturing or
related processes contributed to the contamination. Thus, the retrospective sites were expected to
provide EPA with information regarding key factors that may be associated with drinking water
contamination (US EPA, 2011b).

In 2011 EPA also began conducting investigations at the five selected retrospective case study locations
in Washington County, Pennsylvania (southwestern Pennsylvania); Bradford County, Pennsylvania
(northeastern Pennsylvania); Wise County, Texas;  Las Animas and Huerfano counties, Colorado (Raton
Basin); and Dunn County, North Dakota (Killdeer).  The Killdeer Retrospective Case Study was  conducted
in Dunn County, North Dakota, near the city of Killdeer, where oil is being recovered from the Bakken
Shale (Figure  1).  This case study differs from the other EPA retrospective case studies in that it focuses
on an oil well where a  known release occurred during the hydraulic fracturing process. Specifically, a
blowout occurred in the  Franchuk 44-20 SWH well in September 2010, during the fifth stage of a 23-
stage hydraulic fracture (Jacob, 2011). This resulted  in a  release of hydraulic fracturing fluids, oil, and
flowback water onto the land surface and possibly into the Killdeer aquifer. The release occurred when
an inner string of casing burst due to over-pressurization during the hydraulic fracturing process. The
release prompted state action, which led to the installation of monitoring wells on and around the well
pad; monitoring of nearby domestic wells, water supply wells  (wells that supply water for oil  and gas
activities), and municipal wells; removal of contaminated soil; and installation of a liner. Table 1  lists the
composition of the hydraulic fracturing fluid used and provided by the state. The North Dakota
Industrial Commission's (NDIC) Oil and Gas  Division and the North Dakota Department of Health's
(NDDWQ) Division of Water Quality subsequently invited EPA to consider Killdeer as a retrospective case
study location (US EPA, 2012).

Although the  blowout  is a potential  source of contamination of the Killdeer aquifer, it was not known at
the time of the blowout whether the aquifer had been previously impacted by contamination from
other sources. Therefore, a comprehensive assessment of the ground water around the well pad was
conducted as part of this study to first determine an  impact and then to account for all potential  sources
of contamination. Two potential pathways  for contamination of the Killdeer aquifer from the blowout
were considered:  (1) Direct release from the Franchuk wellbore laterally into the Killdeer aquifer and (2)
Indirect contamination from surface infiltration of released fluids down into the Killdeer aquifer.

Retrospective Case Study in Killdeer, North Dakota                                                May 2015
2. Purpose and  Scope
As a component of EPA's National Study of the Potential Impacts of Hydraulic Fracturing on Drinking
Water Resources (US EPA, 2012), five retrospective case studies were conducted to investigate reported
instances of drinking water resource contamination in areas of natural gas development and use of
hydraulic fracturing technology. These studies were intended to inform primary research questions
related to the hydraulic fracturing water cycle (US EPA, 2012).

This report presents the results of the retrospective case study conducted near the city of Killdeer, in
Dunn County, North Dakota. This report also describes the changes in general water quality,
geochemistry, and isotopic parameters of shallow ground water in the Killdeer aquifer that may have
resulted from the blowout that occurred in the Franchuk 44-20 SWH well. This study is focused on the
September, 2010 blowout event that occurred during the fifth stage of a 23-stage hydraulic fracture of
the Franchuk well.  Water quality results are used to evaluate the potential impacts on drinking water
resources, if any, from various land use activities  not restricted to shale-oil drilling and production
because pre-development water quality information at the Franchuk well pad was available. The
evaluation of potential impacts includes consideration of the chemicals used in hydraulic fracturing of
the Franchuk well, and analyses of dissolved gases, deep brine geochemistry in relation to shallow
ground water geochemistry, historical ground water quality for the Killdeer aquifer in Dunn County, and
time-dependent geochemical trends.  Potential causes of water quality impairment that were evaluated
include: industrial/commercial land  use; historical land use (e.g., farming); current drilling
processes/practices; historical drilling practices; and naturally occurring sources of contamination.

This report presents analytical data for water samples from the Killdeer site representing domestic wells,
water supply wells, municipal wells, and monitoring wells sampled at least twice during three rounds
spanning 15 months (July 2011, October 2011, and October 2012).  The water samples were analyzed
for up to 230 constituents, including organic compounds, nutrients, major anions, major cations, trace
elements, dissolved gases, and selected isotopes.  Ground water quality data  and summary statistics are
presented for sampled constituents. In addition to chemical data collected specifically for this study, the
report includes analysis of historical data from the USGS NWIS database, the North Dakota State Water
Commission (NDWC) database, and  from Klausing (1976) for the Killdeer aquifer in Dunn County.

Each of the retrospective case study sites differs in geologic and hydrologic characteristics; however,
generally similar research approaches were followed at each case study location to assess potential
drinking water impacts. The scope of this study includes: sampling and analysis of water wells, literature
review of background geology and hydrology; selection of sampling locations  and the development of a
site-specific quality assurance project plan (QAPP); sampling and analysis of water wells; analysis of
historical background data and evaluation of new results against background  data; statistical and
geochemical evaluation of water quality data; evaluation of impacts observed with specific sources of
contamination, and further refinement of relationships between the sources of contamination  and the
observed impacts on water quality.

3. Study Area  Background
3.1.   Geology
Dunn County is situated on the Missouri Slope Uplands of the Great Plains Province. The eastern
portion of Dunn County shows evidence of glaciation, while the western third does not. The Missouri
Slope Uplands are characterized by gently rolling hills interrupted by isolated buttes (topographic highs
with flat tops and steep sides). In the northern part of the county, the Missouri Slope is interrupted by
the Little Missouri River Badlands. The Killdeer Mountains (composed of two large mesas) are a major
geographic feature within the county. The mesas rise approximately 700 feet (ft) above the surrounding
topography, with the highest point in the county located on South Killdeer Mountain (3,281 feet)
(Murphy, 2001).

Figure 2 presents a stratigraphic column of Dunn County. The geology of Dunn County consists of thick
sequences of Paleozoic (250 to 540 million years old), Mesozoic (65 to 250 million years old), and
Cenozoic (0 to 65 million years old) rocks, which have accumulated in the Williston basin.  The beds dip
slightly to the north-northwest into the center of the basin. The estimated top of the Precambrian
crystalline rocks is between 11,000 and 13,400 feet below sea level in Dunn County (Heck, 1988;
Murphy, 2001; Heck et al., 2013).

Approximately 7,500 feet of Paleozoic rocks underlie Dunn County (Murphy, 2001). The Paleozoic
sequence in  North Dakota is predominantly carbonate rocks, although clastic rock formations occur at
both the beginning and end of this time period.

Mesozoic rocks in  North Dakota are primarily marine shales, with non-marine deposits at the base
(Inyan Kara Formation) and at the top (Hell Creek Formation)  of this interval (see Figure 2). In Dunn
County, the Mesozoic rocks are approximately 5,400 feet thick (Carlson and Anderson, 1966; Murphy,
2001).  In North Dakota, the Cretaceous rocks are split into three stratigraphic groups: Dakota,
Colorado, and Montana (Murphy, 2001).

Cenozoic rocks in Dunn County include the Fort Union Group (Ludlow, Cannonball, Slope, Tongue River,
and Sentinel Butte formations) and the Golden Valley, White River, and Arikaree formations (Figure 2).
The Fort Union Group is approximately 100 feet thick and is made up  of the non-marine Ludlow
Formation, which comprises alternating beds of sandstone, siltstone,  claystone, mudstone, and lignite
(soft coal). The Ludlow Formation is overlain  by the Slope Formation  in the Little Missouri River Valley
and the marine Cannonball Formation in the Missouri River Valley (Murphy,  2001).

The Sentinel Butte formation is present at the surface in at least 75 % of the county and is the oldest
strata exposed in the county. The Sentinel Butte Formation consists of alternating beds of sandstone,
siltstone, mudstone, claystone, and lignite. Several thick coal beds are present in the Sentinel Butte
Formation in Dunn County. At least one of these coals, the Dunn Center bed, has been considered  for
possible mining (Murphy, 2001).

Soils in Dunn County primarily consist of tertiary  alluvial and glacial deposits. The deposits generally
consist of clay, silt, sand, and gravel derived from local bedrock (USDA, 2013). These properties give an
indication of the movement of water and other parameters from the surface to underlying aquifers and
the surface runoff potential, which is important because the Franchuk well blowout created a surface

spill. The possibility that the spilled fluid leached is an important potential pathway of contamination to
reach the Killdeer aquifer.

Figure 3 presents a soil survey map of the soil types near the Franchuk well pad. Twelve different soil
series are present near the well pad (USDA, 2013), and these 12 soil series, alone or mixed, represent
the 18 soil types located near the Franchuk well. Table 2 lists these soils and selected soil properties
(USDA, 2013). The Franchuk well pad is situated on the Velva fine sandy loam (see  Figure 3). Based on
the properties listed in Table 2, it is expected that a fluid spilled at the soil  surface would likely infiltrate
through the vadose zone and into the Killdeer aquifer.

3.2.   Hydrology
Background information on the hydrology of Dunn County is summarized from Klausing (1976).
Numerous rivers, streams, and creeks flow through the county. Spring Creek and the Little Missouri,
Knife, and Green rivers are the primary rivers in the county (Klausing, 1976).  The Missouri and Little
Missouri rivers drain the northern portion of the county; Spring Creek drains the central portion; and the
Little Knife, Knife, and Green rivers drain the southern portion of the county (Murphy, 2001).  Most rural
areas and the cities of Halliday and Killdeer get their water from private and public wells from the
Killdeer Aquifer (Klausing, 1976).

Aquifers in  Dunn County are found in rocks that were deposited before glaciation and within areas of
glacial deposits. Glacial deposits in Dunn County consist of till and glaciofluvial sand and gravel. The
primary aquifers  lie within sand and gravel deposits that are confined to glacial melt-water channels and
include the Killdeer, Horse Nose Butte,  Knife River, and Goodman Creek aquifers. In addition to aquifers
located in glacial  deposits, other aquifers in consolidated deposits include the Fox Hills, Hell Creek,
Cannonball, Ludlow, Tongue River, and Sentinel Butte Formations (Klausing, 1976). The Killdeer aquifer
is of particularly importance in this study because it directly underlies the Franchuk 44-20 SWH well pad
and because nearby water wells are completed within the Killdeer aquifer. The Killdeer aquifer
underlying the well pad is unconfined to semi-confined.

The Killdeer aquifer occupies an area of about 74 square miles (mi2) in Dunn County (see Figures 4 and
5). The aquifer is composed predominantly of fine to medium sand and is generally overlain by clay and
silt soils (Klausing, 1976).  Several test holes indicate that fine to coarse gravel occurs near the base. The
maximum thickness of the aquifer is 233 feet, and the mean thickness is 80 feet. During the study, the
depth to water ranged from 19.8 to 33.6 feet below ground surface (bgs).

The aquifer is recharged by infiltration of precipitation.  Water levels in the aquifer range from about 0.3
feet (0.09 meters) below ground surface to about 37 feet (11 meters) below ground surface. Seasonal
fluctuations in the water table range from about 1 foot (0.3 meters) to a maximum of about 7 feet (2
meters). The minimum  seasonal fluctuations occur in a  confined portion of the aquifer, whereas the
maximum fluctuations occur in an unconfined portion (Klausing, 1976).

In general, the water is hard and consists of either a sodium-bicarbonate type or a sodium-sulfate type.
Water obtained from the  northern portion of the aquifer is of better quality than water obtained from
the southern portion. Total dissolved solids (TDS) in the northern portion rarely exceed 1,100 milligrams
per liter (mg/L), but TDS commonly exceed 2,000 mg/L in the southern portion of the aquifer (Klausing,
1976).

According to information  provided by Terracon (the contractor to Denbury Onshore, LLC)  to the North
Dakota Department of Water Quality (NDDWQ), the ground water flow direction is to the southwest and
has a relatively uniform gradient of 0.0009 to 0.0008 ft/ft.  Given the shallow gradients (determined at
the site), ground water flow direction and gradient could vary seasonally depending on precipitation and
water usage.  The North Dakota State Water Commission stated that the ground water flow within the
Killdeer aquifer is < 1 ft /year (Helms, 2010).

The Sentinel Butte aquifers consist of poorly consolidated sandstone and fractured lignite.  The
sandstone aquifers within the Sentinel Butte formation are generally sandstone with clay and silt.
Thicknesses range up to 119 feet. Transmissivities from three tests from lignite zones in the Sentinel
Butte Formation ranged from 920 to 49 square feet per day (ft2/day).  The lignite aquifers are randomly
spaced throughout the formation and range in thickness from 1 to 20 ft.  Wells generally yield  1 to 200
gallons per minute (g/min), but not all lignite beds will yield water. Water from both aquifer zones is
generally a hard to very hard, sodium-bicarbonate type (Klausing, 1976).

3.3.   Oil and Gas Production
The existence of hydrocarbons in North Dakota and the Williston Basin was known  before 1900, and the
area has a long history of hydrocarbon development (Heck et al., 2013).  Natural gas was first reported
in the 1890s from artesian wells in Cretaceous formations near Edgely, North Dakota (Heck et al.,  2013).
The Cedar Creek gas field was the oldest commercial hydrocarbon production field  in North Dakota and
first produced in 1929 (Heck et al., 2013). North Dakota,  in 2013, ranked second in terms of oil
production in the United States (USEIA, 2014).

In Dunn County, oil and gas production began in 1959 and is produced primarily from 18 oil fields
(Murphy, 2001). Until 1999, production was from the Mission Canyon Formation (Lower Mississippian
age) in the  Little Knife field, which produced more than 49 million barrels (bbls) of oil (Murphy, 2001).
Between  1990 and 2006, oil production rates ranged from 60,000 to 160,000 bbls per month from
approximately 100 wells (Battelle, 2013).  From 1990 to 2005, natural gas production in Dunn County
ranged from 4,000,000 to 5,000,000 thousand cubic feet  (MCF) per month. When horizontal drilling
began in 2005, this volume increased exponentially, reaching more than 13,000,000 MCF per month by
2011 (Battelle, 2013). Approximately 1,095 conventional oil and gas wells are completed in Dunn
County; some uncertainty is associated with this number  because of incomplete historical records
(Battelle, 2013). Today, the Madison and Bakken Formations account for most of the oil and gas
production in Dunn County (Figure 6; Battelle, 2013).

3.4.   Land Use
Dunn County is a sparsely populated (population of 3,967), rural county in North Dakota (U.S. Census
Bureau, 2012) and covers approximately 2,082 square miles (mi2) (U.S. Census Bureau, 2012). Unlike
other counties in North Dakota, Dunn County has both prairie and badland areas, as well as the Killdeer
Mountains in the northwest portion of the county (Dunn County, 2012).  Until recently, the county's
economy depended on ranching, farming, and recreational activities (City of Killdeer, 2013). Recently,
gas and oil production has increased dramatically in scale and importance (Dunn County, 2012).

Retrospective Case Study in Killdeer, North Dakota
May 2015
Although Dunn County experienced a short-lived oil boom in 1976, oil production increased rapidly in
the county beginning in 2006 because of the new hydraulic fracturing-based exploitation of oil reserves
in the Bakken Shale (NDIC, 2013).

Land uses in Dunn County are depicted on Figure 7. The land use map was created using data from the
National Land Cover Database (NLCD) for Dunn County for 1992 and 2006. Table 3 presents a summary
of these data (USGS, 2012a).  The NLCD is based on 30-meter resolution data from the Landsat satellite,
and the dataset for 2006 was the most recent one available.

Although the data for land use in the two years are not comparable due to changes in input data and
mapping methodologies (Multi-Resolution Land Characteristics Consortium, 2013), the NLCD data
indicate that, in both years, grassland/herbaceous land and row/cultivated crop land (i.e., land suitable
for grazing or used for growing crops) were the largest land use categories in the county. Additional
analyses of land use and land use changes, with particular focus on the area adjacent to the sampling
locations of this study, are presented in Appendix C.

3.5.   Other Contaminant Sources
Once an impact on water quality was determined, a consistent approach was adopted for evaluating
potential contaminant sources in order to help determine whether hydraulic fracturing was the cause or
one of the causes of alleged impacts on water quality.

To determine whether any potential sources of contamination unrelated to hydraulic fracturing
activities may have impacted ground water and surface water in the study area, a detailed background
assessment, including a search of relevant databases/information sources listed below, was conducted.
The detailed findings of this background assessment and search are provided in Appendix C.

The following databases and information sources were considered in the evaluation of alternative
contaminant sources:

    •   Environmental  Records Search: Environmental records searches were performed by obtaining
       environmental record reports from Environmental Data Resources,  Inc. (EDR).  EDR provides a
       service  for  searching publically   available databases  and  provides  data from   their own
       proprietary databases.

    •   Well Inventory:  Existing oil and gas well inventories were prepared on the same search areas
       used for the EDR reports using the North Dakota Department of Mineral Resources Division of
       Oil and Gas database.

    •   State Record Summary: The North  Dakota Department of Mineral Resources Division of Oil and
       Gas database was used to find up-to-date well  records for the study areas.

The evaluation of other contaminant sources in the study area considered all potential contaminant
sources that could contribute to any detected levels of surface and/or ground water contamination. To
conduct an effective evaluation, all hypothesized causes of an environmental impairment needed to be
"sufficiently credible" (US EPA, 2000a) to be included in the analysis. Candidate alternative contaminant
sources were categorized as follows: industrial/commercial land use; historical land use (e.g., farming
and mining); historical drilling practices; and naturally occurring sources.

Based on the review of the environmental records search, nine potential sources of contamination were
identified. Eight of the nine sources were USTs where leaks have occurred or potentially occurred.  The
other was an automotive service station where there may have been unreported releases of automotive
fluids. All these locations were within 0.5 miles of NDGW16. In addition, oil and gas well inventories
were obtained.  This revealed that 35 oil and gas wells were within a 3-mile radius of the Franchuk well
and seven well were within a 1-mile radius of the well.  A state record search did not identify any notices
of violations for any of these wells.

A report produced by Battelle (2013) stated that the most significant causes of water quality impacts in
Dunn County were agriculture; oil and gas activities; wastewater discharges; industrial, manufacturing
and commercial activities; and other nonpoint sources. In Dunn County, agriculture comprises a
significant portion of the economy and land use, with approximately 1,800 square miles dedicated to
this activity (Battelle, 2013). Agricultural impacts on ground water include nutrients, pathogens,
herbicides, insecticides, fungicides, and fertilizers (Battelle, 2013).  Battelle (2013) also suggests that oil
and gas activities are potential sources of impacts on ground water. The oil and gas activities cited

include conventional and unconventional oil and gas development and saltwater disposal wells (Battelle,
2013). In the Battelle report (2013), wastewater discharges included centralized waste water treatment
facilities, septic systems, cesspools, and permitted direct discharges to surface water. According to
Batelle, these types of discharges could potentially cause impacts to ground water quality by discharging
pathogens, household and industrial chemicals, suspended solids, increased biochemical oxygen
demand, and nutrients (Battelle, 2013). Battelle (2013) also discussed industrial, manufacturing, and
commercial activities and reported that these were primarily construction, transportation, and repair
and maintenance activities (leaking USTs fall into this category).  Metals, acids, caustics, cyanides,
polychlorinated biphenyls, poly aromatic hydrocarbons, chlorinated solvents, petroleum hydrocarbons,
BTEX (benzene, toluene, ethylbenzene, and xylenes) compounds, and oxygenates were the
contaminants of concern that could potentially impact ground water in Dunn County (Battelle, 2013).  A
final category discussed in Battelle (2013) was nonpoint sources, which included storm water runoff
(urban, residential, and roads) and sewer overflows. They listed the following contaminants from
nonpoint sources that could potentially impact ground water quality:  suspended solids, metals,
nutrients, organic compounds, pathogens, and volatile organic compounds (VOCs) (Battelle, 2013). It is
important to note that for ground water impairments, they did not distinguish data based on which
aquifer the water quality impairment was in or impairments near the Franchuk well pad. Although
Battelle reported ground water contamination, there is uncertainty about its applicability to this study,
which focuses on the Killdeer aquifer and the localized extent of the Killdeer aquifer being investigated.

4.1.   Sampling Locations
Water quality samples were collected from three domestic wells, nine monitoring wells, one state well
(used to monitor water levels in the Killdeer aquifer), one municipal well, and two water supply wells.
Three sampling rounds occurred in July 2011, October 2011, and October 2012 (Table 4). Samples were
analyzed for up to 230 constituents, including field parameters, major ions, nutrients, trace metals,
VOCs and semi-volatile organic compounds (SVOCs), diesel-range organics  (DRO), gasoline-range
organics (GRO), glycol ethers  (diethylene, triethylene, and tetraethylene glycol and 2-butoxyethanol),
low-molecular-weight acids (lactate, formate, acetate, propionate, isobutyrate, and butyrate),
alkylphenols, ethoxylated alcohols, ethoxylated alkylphenols, dissolved gases (methane, ethane,
propane, and butane), and selected stable isotopes (518OH2o, 52HH2o, and 87Sr/86Sr; see Appendix B).

As noted above, the Killdeer aquifer underlies the Franchuk well pad. The  Franchuk wells are located
approximately 2.5 miles outside the wellhead protection zone of the City of Killdeer's municipal water
supply wells.  In addition, several domestic wells, farm wells, and supply wells for drilling and hydraulic
fracturing are located approximately 0.5 miles downgradient of the Franchuk 44-20 well.

The geographic distribution of the Killdeer aquifer is shown on Figure 4. A  geologic cross section of the
aquifer near the Franchuk well  is shown on Figure 5 (Shaver, 2009).

Nine monitoring wells were installed immediately after the spill in locations where contamination was
suspected based on hydrogeologic conditions at the site and data collected by the North Dakota
Industrial Commission (NDIC) and Terracon.  Four ground water monitoring wells (NDGW01 through
NDGW04) were installed by Terracon (contracted by the well operator, Denbury Resources, Inc.) in
September 2010 to monitor for potential ground water contamination in the Killdeer aquifer. An
additional five monitoring wells (NDGW05 through NDGW09) were installed at the site in April 2011, by
Terracon. Wells NDGW05 and NDGW06 were placed upgradient and within 20 feet of the Franchuk
wells. Wells NDGW07 through NDGW09 were placed similarly to wells NDGW05 and NDGW06, but
downgradient of the Franchuk wells, and NDGW09 was nested with NDGW08.  NDGW08 was screened
in a shallower zone of the Killdeer aquifer, and NDGW09 was screened near the bottom of the Killdeer
aquifer. The draft boring logs of the monitoring well locations, prepared by Terracon, identified fine to
medium silty sand as the dominant aquifer material, with varying silt content. Some logs reported sandy
clay or gravelly sand horizons. While drilling NDGW09, bedrock was encountered at 205 feet below
                                              25

ground surface (bgs), coal was encountered from 205 to 207 feet bgs, and shale was encountered from
207 to 213 feet bgs, which suggests that this well may have actually penetrated into the Sentinel Butte
aquifer. Wells NDGW01, NDGW02, NDGW03, NDGW05, and NDGW07 were completed to depths less
than 50 feet bgs. NDGW04 was completed to a depth of 72 feet bgs, NDGW06 was completed to a
depth of 70 feet bgs, NDGW08 was completed to a depth of 120 feet bgs, and NDGW09 was completed
to a depth of 213 feet bgs. The length of the screened intervals for the monitoring wells ranged from 10
to 40 feet. Except for NDGW09, the depth to ground water in all monitoring wells is within a few feet of
one another at approximately 30 feet bgs. The elevation of ground water in NDGW09 is consistently 10
feet higher than in the other monitoring wells. NDGW09 is screened in clay and bedrock, and a 1-foot-
thick horizon of fine to medium sand is present in the clay.

These nine monitoring wells, along with three domestic wells, two water supply wells (used for drilling
activities in the area), one state well, and one city of Killdeer municipal supply well,  were part of the
periodic sampling program. The sampling locations are identified in Table 5 and are shown on Figure 8.
The domestic wells near the Franchuk 44-20 SWH well location were sampled via  homeowner taps.
According to the state, the domestic wells are screened in the Killdeer aquifer (NDWC, 2013).

4.2.   Water Collection
Sample bottles for each location were uniquely labeled prior to each sampling round, and all labels were
color-coded by analytical parameter.  See Table Al (Appendix A) for pre-cleaned bottle types and
number of sample bottles needed for each laboratory analysis.

Both field-filtered and unfiltered water samples were collected. Unfiltered samples were collected first,
and unfiltered samples that could contain volatile components were collected before samples with less
volatile components. The unfiltered samples were analyzed for the following parameters: dissolved
gases, VOCs, SVOCs, DROs GROs, glycols, low-molecular-weight acids, ethoxylate alcohols, alkylphenol
ethoxylates, alkylphenols, and total metals.  Filtered samples were collected by placing a 0.45
micrometer (u.m) disposable capsule filter at the end of the polyethylene tubing and passing the water
stream through the filter into the sample container. Approximately 100 milliliters (ml) of ground water
was passed through the filter, to waste, before filling sample bottles. Filtered sample parameters
included dissolved metals, anions, nutrients (ammonia, nitrate + nitrite), dissolved inorganic carbon
(DIG), dissolved organic carbon (DOC), 618O/62H of water, and  strontium isotope. A  more detailed
description of the sampling methods is provided in the QAPP (Beak, 2013). Not all parameters
mentioned above were analyzed for each sampling round. Table 4 identifies the types of samples
collected during each sampling round. Sampling methods, sample preservation, and handling are
discussed in detail in the QAPP (Beak, 2013) and is described in Appendix A and Table Al.

Because of the different types of well construction, differences in  the pumps in the wells, and intended
well uses of the sampled wells in this study, a well volume approach linked with the stabilization of
geochemical parameters was used for purging all the different types of wells (Yeskis and Zavala, 2002).
The purging methods for the different well types are discussed below.

4.2.1.  Purging and Sampling at Domestic and Municipal Wells
Domestic well samples were collected as close to the wellhead as  possible, prior to any water treatment
or pressure tanks. The well tap was turned on and a clean piece of polyethylene tubing was connected
to the sampling port, and the other end of the tubing was connected to a flow cell equipped with a YSI
5600 multi-parameter probe. The well was allowed to purge for 20 minutes before  monitoring of
geochemical parameters was initiated. The well was then allowed to purge until stable geochemical
parameters (specific conductivity (SpC), pH,  dissolved oxygen (DO), and oxidation-reduction potential
(ORP)) were achieved.  Once stable geochemical parameters were obtained, the samples were collected.
All samples were preserved immediately upon collection (see Appendix A, Table Al) and stored on ice
prior to leaving the sampling location.

4.2.2.  Purging and Sampling at Supply Wells
Water supply wells are designed for high flows to fill water trucks; the flow rates cannot be adjusted and
there is no tap from which samples can be collected. Terracon, the contractor for the operator,
designed an insert with a tap that is placed between the  well and  the truck tank to collect samples.
After the sampling insert was connected to the well and the tanker, the dedicated pump was powered
on. The water was allowed to flow for one to two minutes to purge any water in the lines before sample
collection was initiated. A sub-sample was collected to measure geochemical parameters before  the
water samples were collected. All samples were preserved immediately upon collection (see Appendix
A, Table Al) and stored on ice before leaving the sampling location.

4.2.3.  Purging and Sampling at Monitoring Wells
Monitoring wells were sampled using the following method: Water level measurements were taken
before pumping the wells. Water level measurements were taken using the Robert S. Kerr
Environmental Research Center Standard Operating Procedure (RSKSOPj-326. A dedicated piece of
tubing was connected to the sampling port of the well and the dedicated pump was powered on.  Water
was allowed to pass through a flow cell equipped with an YSI 5600 multi-parameter probe (or
equivalent) to track the stabilization of the geochemical parameters. Once values for the geochemical
parameters stabilized, the flow cell was disconnected and samples were collected. All samples were
preserved immediately upon collection (see Appendix A, Table Al) and stored on ice before leaving the
sampling location. The water levels were measured again following sample collection to see whether
significant drawdown had occurred.

4.2.4.  Purging and Sampling at the North Dakota State Water Commission (NDWC) Wells
A portable bladder pump (QED Sample Pro or equivalent) was used to sample the NDWC well. Water
level measurements were taken before purging the well.  The portable bladder pump was then lowered
into the well, and the pump intake location was placed within the screened interval of the well. Tubing
from the  sampling port was connected to the flow cell and the pump was powered on. Because of the
low flow rates (less than 50 milliliters per minute [mL/min]), the well was purged for a minimum of six
hours before geochemical parameters were measured. Once the values for the geochemical parameters
stabilized, the flow cell was disconnected and samples were collected.  All samples were preserved
immediately upon collection (see Appendix A, Table Al) and stored on ice before leaving the sampling
location.  The water levels were measured again following sample collection to see whether significant
drawdown had occurred.

4.2.5.  Sample Handling
At the conclusion of each day, samples were organized by analytical parameter, placed together in
sealed Ziploc plastic bags, and transferred to coolers filled with ice.  Glass bottles were packed with
bubble wrap to prevent breakage.  A temperature blank and chain-of-custody form were placed in each
cooler. Coolers were sealed and affixed with a custody seal and sent to the appropriate lab, via express
delivery, within 24 hours  of collection.

4.3.   Water Analysis

4.3.1.  Field Parameters
Temperature (US EPA Method 170.1), specific conductivity (SpC) (US EPA Method 120.1), pH (US EPA
Method 150.2), ORP, and DO (US EPA Method 360.1) were continuously monitored and logged during
well purging using an YSI 556 multi-parameter probe. YSI electrodes were calibrated every morning
before use. Performance checks were conducted after an initial calibration, again at midday, and at the
end of each day. The National Institute of Standards and Technology (NIST)-traceable 1413
microSiemens per centimeter (u.S/cm) specific conductance standard was used for calibration. NIST-
traceable buffer solutions (4.00, 7.00, and 10.01) were used for pH calibration. An ORP standard  (Zobell
Solution) was used to calibrate the ORP sensor.  DO sensors were calibrated with air. Electrode
performance was checked using the YSI 5580 Confidence Solution. Prior to deployment to the field, all
calibration and performance standards were checked to ensure that they had not expired or would
                                             29

expire during the sampling round. Duplicate field measurements are not applicable to measurements in
a flow-through cell (RSKSOP-211v3).

Once the geochemical parameters had stabilized, a 1-liter sub-sample was collected for field
determinations of alkalinity, turbidity, ferrous iron, and dissolved sulfide. Alkalinity measurements were
determined by titrating ground water with 1.6N sulfuric acid (H2SO4) to the bromcresol green-methyl
red endpoint using a HACH titrator (US EPA Method 310.1). Turbidity measurements (US EPA Method
180.1) were determined with a Hach 2100Q portable meter. Ferrous iron measurements were collected
using the 1,10-phenanthroline colorimetric method (HACH DR/890 colorimeter, Standard Method 3500-
FeB for Wastewater).  Dissolved sulfide measurements were collected using the methylene blue
colorimetric method (HACH DR/890 spectrophotometer,  Standard Method 4500-S2"D for Wastewater).

Hach spectrophotometers (ferrous iron and sulfide) and turbidimeters (turbidity) were inspected before
going to the field, and their function was verified using performance calibration check solutions. The
ferrous iron accuracy was checked by making duplicate measurements of a 1 mg Fe/L standard solution
(HACH Iron Standard solution, using Ferrover pillows); the results were between 0.90 and 1.10 mg Fe/L.
Accuracy and precision of sulfide measurements were checked using a standard solution of sodium
sulfide prepared in the laboratory that had been titrated  with sodium thiosulfate to determine its
concentration. Accuracy should be within ±10 percent of the expected concentration and the
coefficient of variation should be less than 20 percent.  Turbidity was checked against turbidity
standards supplied by Hach (StablCaf Calibration Set for the HACH 2011Q), which consist of four
standards (20 nephelometric turbidity units [NTU], 100 NTU, and 800 NTU) with a 10 NTU performance
check standard. The performance check must be ±10 percent of the known concentration.  Titrators
used for alkalinity measurements were checked using a 250 milligrams per liter (mg/L) standard made
from sodium bicarbonate (NaHCO3). The performance check must be ±10 percent of the known
concentration. Blanks (deionized water) and performance calibration check solutions (where applicable)
were measured at the beginning of the day, at midday, and at the end of the day for each parameter.

4.3.2.  Analytical Methods for Ground Water
Water samples were collected and analyzed using the methods identified in Table Al, Appendix A.
Samples were collected and delivered to seven laboratories for analysis: EPA Office of Research and

(ORD/NRMRL/GWERD), Ada, Oklahoma; Shaw Environmental (name changed to CB&I due to change in
ownership during study), Ada, Oklahoma; EPA Region 8, Golden, Colorado;  EPA Region 3, Fort Meade,
Maryland; U.S. Geological Survey (USGS), Denver, Colorado; Southwest Research Institute (SwRI), San
Antonio, Texas; EPA ORD/National Exposure Research Lab (NERL), Las Vegas, Nevada; and a Contract
Laboratory Program (CLP) laboratory (A4 Scientific, Inc., Woodlands, Texas) (see Appendix A, Table Al).

Anions, nutrients, DIG, and DOC were analyzed in-house (GWERD General Parameters Laboratory, Ada,
Oklahoma). Quantitative analyses of the major anions bromide, chloride, fluoride, and sulfate were
determined by capillary ion electrophoresis (US EPA Method 6500, RSKSOP-276v4) using a Waters
Quanta 4000 capillary ion analyzer for all sampling rounds. To provide better resolution of the bromide
in a high chloride matrix, bromide samples containing high chloride levels were also analyzed in round 2
using flow injection analysis (Lachat QuickChem 8000 Series flow injection analyzer RSKSOP-214v5) and
in round 3 with the capillary ion analyzer (US EPA Method 6500, RSKSOP-288v3 for high chloride levels).
Nutrients (nitrate + nitrite, ammonia) were measured by  flow injection analysis (US EPA Method 350.1

and 353.1, RSKSOP-214v5) for all rounds of sampling. Iodide was measured using flow injection analysis
(RSKSOP-223v2) only for sampling round 3. The carbon concentrations of DIG and DOC in aqueous
samples were determined via combustion and infrared detection (US EPA Method 9060A, RSKSOP-
330vO) using a Shimadzu TOC-VCPH analyzer for all sampling rounds.

Dissolved gases (methane, ethane, propane, and butane), low-molecular-weight acids (lactate, formate,
acetate, propionate, isobutyrate, and butyrate), and the stable isotopes of water (62H, 618O) were
analyzed by Shaw Environmental/CB&l (Ada, Oklahoma).  Dissolved gases were measured using gas
chromatography (Agilent Micro 3000 gas chromatograph (RSKSOP-194v4 and -175v5) for all sampling
rounds. The concentrations of low-molecular-weight acids were determined using high-performance
liquid chromatography (HPLC) (Dionex ICS-3000, RSKSOP-112v6) for all sampling rounds. Hydrogen
(62H) and oxygen (618O) isotope ratios for aqueous samples collected were determined by isotope-ratio
mass spectrometry (IRMS) (RSKSOP296vl) for sampling round 2 and  by cavity ring-down spectrometry
(Picarro L2120J CRDS, RSKSOP-334vO) for sampling round 3.

The analyses of DROs, GROs, and SVOCs  in water samples were completed by EPA Region 8 laboratory
(Golden, Colorado) for all sampling rounds. DROs and GROs were determined by gas chromatography
(GC), using a gas chromatograph equipped with a flame ionization detector (US EPA Method 8015B;
Agilent 6890N GC).  The concentrations of SVOCs were determined by GC/mass spectrometry (GC-MS),
(US EPA Method 8270D; HP 6890 GC and HP 5975 MS).

VOCs were measured by Shaw Environmental/ CB&I (Ada, Oklahoma) for all sampling rounds. The
samples were analyzed using automated headspace GC/MS (US EPA  Methods 5021A and 8260C; Agilent
6890/5973 Quadrupole GC/MS).

Both dissolved (filtered) and total (unfiltered) metal samples were analyzed by Shaw Environmental for
rounds 1 and 2.  Metals were analyzed using inductively coupled plasma-optical emission spectroscopy
(ICP-OES) for all dissolved and total metals (US EPA Methods 200.7; RSKSOP-213v4; Optima 3300 DV ICP-
OES). Unfiltered samples were prepared before analyses by microwave digestion (US EPA Method
3015A). Total and dissolved metal analyses for samples collected during sampling round 3 were
conducted by SwRI (San Antonio, Texas)  in accordance with US EPA Method 6020A (inductively coupled
mass spectrometry [ICP-MS]) and US EPA Method 200.7 (ICP-OES). Unfiltered samples were digested
prior to analyses (US EPA Method 200.7). Mercury concentrations were determined by cold-vapor
atomic absorption (US EPA Method 7470A; PerkinElmer FIMS 400A).

Glycols (2-butoxyethanol, di-, tri-, and tetraethylene glycol) were measured by EPA Region 3 laboratory
in samples collected during sampling rounds 1 and 2. The samples were analyzed by high-performance
liquid chromatography (HPLC) coupled with positive electrospray ionization (ESI+) tandem mass
spectrometry (MS/MS; Waters HPLC/MS/MS with a Waters Atlantis dC18 3u.m, 2.1 x 150 mm column).
Glycol samples for round 3 were analyzed by EPA's NERL  using the same method as EPA Region 3. Over
the course of this case study, the glycol method was in development. A verification study of the method
used for glycol analysis was completed using volunteer federal, state, municipal, and commercial
analytical laboratories. The study indicated that the HPLC/MS/MS method was robust, provided good
accuracy and precision, and exhibited no matrix effects for several water types that were tested
(Schumacher and Zintek, 2014).

Strontium isotopes (87Sr/86Sr) and rubidium (Rb) and strontium (Sr) concentrations were measured by
the U.S. Geological Survey (USGS) (Denver, Colorado; no EPA method) for samples collected during
sampling rounds 2 and 3. High precision (2o = +0.00002) strontium isotope ratio results were obtained
using thermal ionization mass spectrometry (TIMS) (Finnigan MAT 262 and Thermo Elemental Triton).

Acrylamide, alkylphenols, ethoxylated alkylphenols, and ethoxylated alcohols were measured by the
EPA's NERL (Las Vegas, Nevada; no  EPA methods) using methods currently under development (US EPA,
2012).  These were measured for a  limited set of wells in round 2 and for all wells in round 3.

Detection and reporting limits for all analytes, per sample type, are provided in Tables Bl through B8 in
Appendix B.

4.4.   QA/QC
Detailed information concerning QA/QC is presented in Appendix A of this report.  QC samples  included
blanks, field duplicates, matrix spikes, and matrix spike duplicates. All QC sample types were collected,
preserved, and analyzed using methods identical to those used for the water samples collected in the
field (Table 4).  Sample preservation and holding time criteria are  listed in Table Al. Field QC samples
for ground water and surface water sampling, which included several types of blanks and duplicate
samples, are summarized in Table A2. These  included several types of blanks and duplicate samples.
Adequate sample volumes were collected to allow for laboratory matrix spike  samples to be prepared,
where applicable.  Data were checked using the software package AqQA (version  1.1.1) for the  charge
balance and measured SpC versus calculated  SpC checks.  First, the SpC values measured in the field
were compared with a calculated value that is based on anion- and cation-specific resistivity constants
and the measured concentrations of anions and cations in specific ground water samples.  The
agreement between the measured  and calculated values should be within 15%. The second method
was to calculate the charge balance for each solution. This was done by summing and comparing the
net positive and negative charge from the measured concentrations of anions and cations. The
agreement should be within 10%. Poor agreement suggests that one or more major solutes were not
accounted for in the analytical measurements or, otherwise, could point to an analytical error.
Discrepancies in this manner were either qualified or the identity of other sample components  and/or
reason(s) for poor agreement was investigated (Beak, 2013). A more detailed  description of the QA/QC
procedures implementation is presented in the QAPP (Beak, 2013).

Appendix A describes general QA and the results of QC sample analyses, including discussions of chain of
custody, holding times, blank results, field duplicate results, laboratory QA/QC results, data usability,
QAPP additions and deviations, field QA/QC, application of data qualifiers, tentatively identified
compounds (TICs), Audits of Data Quality (ADQ), the field Technical System Audit (TSA), and laboratory
TSAs. All reported data met project requirements unless otherwise indicated by application of  data
qualifiers. In rare cases, data were  rejected as unusable and not reported. Detailed information
concerning QA/QC is presented in Appendix A of this report.

4.5.   Data  Handling and Analysis
For each sampling location in this study, geochemical parameters and the water quality data for major-
ions and other selected inorganic ions collected over the multiple sampling rounds were averaged.  This
approach ensures that more frequently sampled locations are given equivalent weight in the data
                                              32

-------

analysis (Battelle, 2013); however, a shortcoming of this method is that potential temporal variability in
concentration data at a single location is not captured. Intra-site variability of the data collected in this
study was examined by evaluating time-dependent concentration  trends at specific locations. Summary
statistics were calculated for selected parameters after averaging across sampling rounds for each
location (e.g., mean, median, standard deviation, minimum and maximum values). Parameters with
non-detect values were set at half the minimum detection limit; summary statistics determined for
parameters that showed mixed results, both greater than the quantitation limit (>QL) and less than the
quantitation limit ( QL were found and these detections were not consistent through
time at specific sampling locations. Stable isotope and strontium isotope data, used to identify fluid
sources and biogeochemical processes, were not averaged so that the full range of data variability could
be evaluated. Furthermore, historical sources of isotope data for the study were not available, so
weighting was not a data analysis issue.

Historical ground water data for Killdeer were collected from the NWIS (USGS, 2013), the NDWC (2013),
and Klausing (1976) databases. Secondary data from these sources were considered based upon various
evaluation criteria,  such as: (1) did the organization that collected the data have a quality system in
place?  (2) Were the secondary data collected under an approved QAPP or other similar planning
document? (3) Were the analytical methods used comparable to those used for the primary data? (4)
Did the analytical laboratories have demonstrated competency (such as through accreditation) for the
analysis they performed? (5) Were the data accuracy  and precision control limits similar to the primary
data? (6) Are the secondary data source MDLs and QLs comparable to those associated with the
primary data or at least adequate to allow for comparisons? and (7) Were sampling methods
comparable to those used for the primary water quality data collected for this study?  In general, the
necessary accompanying metadata are unavailable for the secondary water quality data sources to fully
assess these evaluation criteria; thus, the secondary data are used with the understanding that they are
of an indeterminable quality relative to the requirements specified for this study (see QAPP; Beak,
2013).

The software package AqQA (version 1.1.1) was used to evaluate internal consistency of water
compositions by calculating cation/anion  balances and by comparing measured and calculated electrical
conductivity values (see Appendix A, Table A26). Major-ion charge balance was calculated by comparing
the summed milliequivalents of major cations (calcium, magnesium, sodium, and potassium) with major
anions (chloride, sulfate, and bicarbonate) in filtered samples using the equation:
                         „,     ,, ,      fn/\    locations—£anions)|                     . .
                         Charge Balance (%) = 7^	 xlOO                (1)
                              5         ^ J    I(2cations+£anions)I                     v '

The calculated charge balance error over the five sampling rounds ranged from 0.1% to 8.7% for surface
and ground water; 88% of the ground water samples collected for this study had a charge balance error
less than 5% (see Appendix A). The gypsum saturation index was determined using the Geochemist's
Workbench package (version 8; Bethke, 2008). Speciation and mineral equilibria calculations were
made by using temperature and concentrations of base species: major cations (Na+, K+, Ca2+, Mg2+),
                                              33

anions (Cl~, SO42~, HCO3~), and pH. Activity corrections were made using the Debye-Huckel equation. The
LLNL (EQ3/6) thermodynamic database was selected for use in the calculations (Delany and Lundeen,
1990). For these calculations, charge imbalance was handled by compensating with chloride for samples
with an anion deficit or by compensating with sodium for samples with a cation deficit.

Once the databases were sorted and filtered, the data from each database were compared to identify
duplicate samples between databases. This comparison was based on the metadata provided in each
database. Based on these metadata, sampling locations within databases where duplicated were
removed.

For the historical datasets, samples with a charge balance error < 15% were used for water-type analysis
and for constructing geochemical plots such as Piper or Schoeller diagrams. In most cases, charge
balance errors exceeding the 15% criterion were due  to missing concentrations of major cations or
anions in the historical datasets. Again, the historical data from locations with multiple sampling rounds
were averaged and summary statistics were determined. Charge balance criteria were not used to
screen data for use in summary statistic calculations or for plotting box-and-whisker diagrams.

Summary statistics for historical data were determined on a reduced-area basis (3-mile radius) in order
to more directly evaluate data from samples collected in nearby locations. Various issues relating to
data quality and applicability of historical data have been previously discussed (Battelle, 2013; US EPA,
2012; Beak,  2013), such as comparability of analytical methods, comparability of analytes, unknown
sample collection methods, and unavailable laboratory QC data and data-quality-related qualifiers.
While recognizing these limitations, historical data are used as the  best points of reference available to
compare with the water quality data collected in this  study.

Statistical evaluations were carried out using the ProUCL (US EPA, 2010b) and Statistica (version 12)
software packages.  Hypothesis testing for the water quality data was performed using parametric
(ANOVA) and nonparametric (Kruskal-Wallis) methods.  An  assumption underlying parametric statistical
procedures is that datasets are normally distributed or can  be transformed to a normally distributed
form; data transformations in some cases included logarithmic functions.  For the analysis of the major-
ion trends, average values were used in the statistical tests and were combined with single observations.
As noted previously, this approach was used to avoid  the undue weighting of locations sampled multiple
times, either in the new data collected for this study or in the historical water quality data.  Post-hoc
tests were performed to determine significant differences among water quality datasets for particular
analytes, including the Scheffe and Kruskal-Wallis multiple comparison tests. A p-value of less than 0.05
was interpreted as a significant difference between compared datasets. Because a large number of
comparisons were made between the data from this study  and the historical water quality data that
encompass numerous  sampling investigations, multiple locations, and extended periods of time, the
problem of multiple comparisons is suggested, that is, the increased likelihood of rejecting the null
hypothesis and flagging significant differences among datasets. Given the exploratory nature of this
study, p-value adjustments were not incorporated (e.g., Bonferroni or Sidak correction factors) and the
traditional significance threshold of 0.05 was applied for the data comparisons.

5. Historic Water Quality
5.1.   National Water Information Systems (NWIS) Database
The NWIS is a large, publically available database of water quality data for the United States (USGS,
2011). Ground water data are available from the NWIS database.

Initially, the data were sorted based on whether the water was surface water or ground water. The
ground water data were then sorted according to the aquifer or formation from which the water had
been collected. Using the state well codes, the data, all prior to 1978, were refined further to water
samples that came from the Killdeer aquifer. Calculations of charge balances revealed that the charge
balances ranged from 0.04% to 4.2%.  There were 25 total data points and all were useable.

5.2.   North Dakota State Water Commission (NDWC) Database
The State of North Dakota maintains a publicly available database containing ground water quality data.
This database is maintained by the North Dakota State Water Commission (NDWC, 2013). Killdeer
aquifer data were downloaded, including the calculated charge balances for all locations.  Only data
prior to 1998 were used. Calculations of charge balances revealed that the charge balances ranged from
0.1% to 3.3%.  All six data points were useable.

5.3.   Klausing Data
Klausing (1976) published ground water data for the Killdeer aquifer in a report obtained from the North
Dakota Geological Survey. Charge balances were calculated for the data in the report and data with
charge balances greater than 15% were not considered for data comparisons. All five data points in this
report for the Killdeer aquifer were useable (charge balances ranged from 0.3% to 1.6%).

5.4.   National Uranium Resources Evaluation (NURE) Database
The National Uranium Resources Evaluation (NURE) database was not used in this study because there
were no data related to the Killdeer aquifer.

5.5.   Produced Water Database
The produced water database shows the concentrations of major anions and cations, pH, and total
dissolved solids (TDS) for produced water in the United States (USGS, 2002). This is a publically available
database maintained by the USGS. The USGS compiled the database from the original Department of
Energy Fossil Energy Research Center and removed redundancies, verified consistency of the data, and
added metadata (USGS, 2002). This database contained analyses of 1,210 produced waters in the
Williston Basin for North Dakota.

5.6.   Limitations to the Determination of Background Using Historical Data
Using historical data to determine background water quality has several limitations (Battelle, 2013;
Reimann et al., 2008; Matschullar et al., 2000; Bowen et al., 2015). Battelle (2013) discussed the
importance of taking into consideration the quality assurance (QA) and sample collection methods in
regards to the use of secondary data and the intended purpose of the database being considered. For
example, EPA STOrage and RETrieval (STORET) database was excluded because it contains samples that
were used for regulatory purposes and thus represents impaired waters rather than background data.  It
                                            35

is not known how or if the NWIS and  NDWC databases screened sampling locations for potential
contamination. Therefore, it is possible that these databases also contain data that are not background.
Other potential limitations of the databases include the following: they may not have the appropriate
spatial distribution of sampling points or temporal distribution of sampling events needed; they may
lack data on trace organic compounds; and they may lack geochemical or isotopic indicators (Bowen et
al., 2015). Bowen et al. (2015) also indicated that many of the watersheds where current hydrocarbon
exploration is occurring had severely  degraded water prior to 1972 and, since 1972, have experienced
improvements in water quality. This  causes the comparisons to historical data to be more difficult and
not straightforward.

6. State-Commissioned Monitoring Data at the Killdeer

   Retrospective Case Study  Location
The state of North Dakota directed the operator of the Franchuk well to initiate site remediation efforts
and ground water monitoring immediately after the blowout occurred. The operator and the contractor
proposed a Remedial Investigation Work Plan that was finalized in March 2011 (Terracon, 2011a). This
document provided information on background and scope of work, the analytical parameters to be
measured and a proposed sampling schedule for the remediation efforts and ground water sampling
(Terracon, 2011a). In addition, standard operating procedures (SOPs) and a Quality Assurance Project
Plan (QAPP) were provided to the state for the Remedial Investigation Work Plan sampling in a separate
document (Terracon, 2011b). The QAPP was finalized in March 2011 and contained information for the
project organization and responsibilities; QA objectives for measurement of data; sampling procedures;
custody procedures; instrument calibration procedures and frequency; analytical procedures; quality
control checks; data reduction, validation and reporting procedures; performance and system audits;
preventive maintenance; specific routine procedures to assess data precision, accuracy, and
completeness; and corrective actions. EPA used similar data collection activities at this retrospective
case study.

The state-commissioned data collected were provided to EPA in spring 2013. Because of the greater
sampling frequency, these data could be compared with the results of EPA study data and used to
potentially fill in data gaps in study data (e.g., time trend analyses). A summary of the state-
commissioned data is presented in Appendix D.

7. Water  Quality Results  from this Study
The following sections describe results and interpretations of the water-quality testing conducted in this
case study, including:  geochemical parameters, major cations, major anions, manganese, and iron;
geochemical parameters (pH and SpC); dissolved gases; organic parameters; and isotopes. Analytical
data obtained during the three sampling rounds are provided in the tables in Appendix B.

7.1.   Initial Study Data Screening
Figure 9 shows the ranges of the major anions and major cations.  NDGW07 and NDGW08 are outliers
when compared with other site wells and historical data for the majority of parameters (chloride,
calcium, magnesium, and sodium). This is a strong indication that NDGW07 and NDGW08 demonstrated
potential impacts on ground water quality. It should be noted that other study wells for parameters
shown in Figure 10 are also outside the historical data ranges; however, there is no pattern that suggests
impacts on ground water quality. In addition, drilling records for NDGW09 indicate that NDGW09 is
partially or entirely screened in the underlying Sentinel Butte aquifer, so differences in water quality
compared  with historical data  or other study wells screened in the Killdeer aquifer would be expected.

A Piper diagram of the study data is provided in Figure 10. This Piper diagram also indicates that the
water quality in NDGW07 and  NDGW08 differs from the other study wells, with the exception of the
October 2012 NDGW06 sample.  The anion trilinear plot indicates that NDGW07 and NDGW08 are
enriched with chloride compared with other study wells. This chloride enrichment is also indicated for
the October 2012 NDGW06 sample. The mixing diamond on the Piper diagram also indicates that
NDGW07 and NDGW08 (black dashed area on plot) are enriched with respect to sulfate + chloride and
slightly enriched with respect to calcium  + magnesium. Unlike the trilinear  plot, the mixing diamond
does not indicate that the October 2012  NDGW06 sample differs from the other study wells.

The differences in water quality in NDGW07 and  NDGW08 are shown for the following parameters:
chloride, calcium, magnesium, sodium, and strontium. These wells are potentially impacted (see the
Specific Focus Topics- NDGW07 and NDGW08 section of this report for further discussion). The
parameters for other study wells, with a few exceptions, appear to be similar. This similarity indicates
that these  wells most likely are not impacted and thus are discussed in relationship to historical
background in the next section.

7.2.   Comparisons with Historical Data
As noted previously, the October 2012 NDGW06 sample appeared to be different from the other study
wells.  To determine if the October 2012 NDGW06 sample was an outlier, a Q-test (Dean and Dixon,
1951; Rorabacher, 1991) was used to determine  if this sample was indeed an outlier.  The Q-test
analysis shows that only chloride for the  October 2012 sample for NDGW06 was an outlier (Table 7).
The state-commissioned data also showed an elevated concentration of chloride in the October 2012
NDGW06 sample. Other samples collected prior to the October 2012 state-commissioned data for
NDGW06 were consistently lower and not outliers.  Based on the study data collected by EPA and the
state, it cannot be determined whether the October 2012 sample for NDGW06 represents an anomalous
sampling point or indicates that NDGW06 is showing that contamination is occurring. However, the
October 2012 sample for NDGW06 should not be consider reflective of unimpacted conditions in
succeeding discussions, rather it should be considered undetermined. It is also important to note that
this data point for the  October 2012 sample will be used for future analysis in this report.

7.3.   Other Parameters

7.3.1.  Dissolved Gases
The dissolved gases analyzed as part of this case study were methane, ethane, propane, and butane.
The NWDC and the NWIS databases and the data presented in Klausing (1976) did not include these as
part of their suite of analyses. However, a report on field screening for shallow gas was available to use
as a comparison (Anderson et al., 2010).

Over the course of the study there were no detectable concentrations of propane or butane. Out of the
31 total samples collected during the study, 10 had detectable concentrations of methane, and all of
these were detected in the October 2011 sampling round. The methane concentrations ranged from
0.0004 to 0.0253 mg/L, with a median concentration of 0.0049 mg/L. Anderson et al. (2010) screened
27 observation wells in Dunn County and only five of the wells had detectable methane, which ranged
from 0.0149 to 0.3978 mg/L. All methane detections in Anderson et al. (2010) were in the central part
of Dunn County in the Killdeer aquifer and the Sentinel Butte-Tongue River aquifer. The information
presented in Anderson et al. (2010) indicates that the detected methane concentrations in the study are
likely representative of the background conditions of the  Killdeer aquifer.

7.3.2.  Volatile Organic Compounds (VOCs)
The NWIS and the NDWC databases and Klausing (1976) did not contain data on VOCs, so  comparisons
with study data were not possible. Acetone, TBA, benzene, toluene, m+p xylene, o-xylene, 1,2,4-
trimethylbenzene, and 1,2,3-trimethylbenzene were the VOCs that had detectable concentrations in the
samples collected.

Retrospective Case Study in Killdeer, North Dakota                                                May 2015


One well with detectable VOCs (NDGW10) is upgradient of the blowout site. In the July 2011 sampling
round, acetone (80.3 micrograms per liter [u.g/L]), benzene (3.77 u.g/L), and toluene (0.45 u.g/L) were
detected. These compounds were not detected in subsequent sampling rounds. The probable source of
these compounds was the PVC cement used during well pump replacement the day prior to sampling
and is not related to the blowout at the Franchuk well. However, the data collected during the study
does not rule out other sources of contamination.

Well NDGW04, downgradient of the Franchuk wells, also had detectable levels of VOCs in the October
2011 sampling round: benzene (0.20 u.g/L), m+p-xylene (0.59 u.g/L), o-xylene (0.50 u.g/L), 1,2,4-
trimethylbenzene (0.39 u.g/L), and 1,2,3-trimethylbenzene (0.26 u.g/L). Benzene, m+p-xylene, 1,2,4-
trimethylbenzene, and 1,2,3-trimethylbenzene were qualified with a "J" qualifier, which means that the
concentration was > MDL and

plastics, surface coatings, detergents, and soaps (Griffiths et al., 1985; Harris et al., 1998; Wess et al.,
1998; Stiles et al., 2008; Serodio and Nogueira, 2006; Teil et al., 2013).

During this study, 80 of the 84 SVOCs compounds analyzed for were not detected.  The SVOCs that were
detected included: 2-butoxyethanol, bis-(2-ethylhexyl) adipate, bis-(2-ethylhexyl) phthalate, and di-n-
butyl phthalate. However, bis-(2-ethylhexyl) adipate, bis-(2-ethylhexyl) phthalate, and di-n-butyl
phthalate are ubiquitous in the environment and are therefore not useful in determining whether
impacts occurred or in identifying a source of contamination (Griffiths et al., 1985; Stiles et al., 2008;
Serodio and Nogueira, 2006; Teil et al., 2013).  These compounds are considered common laboratory
contaminants (WDNR, 2002; Miller, 2015). The 2-butoxyethanol was detected only in the July 2011
sampling round; however, the data were qualified because of blank contamination in field blanks (see
Appendix A) and were not reliable.  Because there were no other detections of 2-butoxyethanol in
subsequent sampling rounds, and because it was not listed as a component of the hydraulic fracturing
fluid used (Table 1), the 2-butoxyethanol detected in the July 2011 was likely due to contamination in
the sampling equipment or sampling containers because it is used commonly in soaps and detergents
(Harris et al., 1998; Wess et al., 1998).

7.3.5.   Diesel Range Organic Compounds/ Gasoline Range Organic Compounds (DRO/GRO)
DROs and GROs were used to screen for petroleum contamination in this study. The summary of all the
data collected for DROs and GROs is presented in  Table B5, Appendix B.

One sample in the July 2011 sampling round (NDGW10) had detectable GRO (77.9 u.g/L); this was the
same sample with detectable VOCs. The GRO  detected in this  sample was possibly from the well pump
replacement the day before the sampling.  NDGW03 and NDGW04 had detectable GRO (20.9 and 23.6
u.g/L, respectively) during the October 2011 sampling round. NDGW04 had detectable VOCs during this
sampling round. As noted in the VOC discussion, this GRO is likely due to contamination during
sampling. GRO was not detected in the October 2012 sampling round.

DRO was detected in all sampling rounds during this study. During the July 2011 and October 2011
sampling rounds, all samples, with  the exception of NDGW02,  had detectable DRO. However, most
samples for the July 2011 sampling round were qualified because of field blanks (see Appendix A). In the
October 2012 sampling round, the following wells were found  to have detectable DRO: NDGW01,
NDGW04, NDGW06, NDGW07, NDGW08, NDGW09, and NDGW14. For the most part, all the wells had
similar concentrations (Killdeer aquifer wells ranged from 25.1 to 92.2 u.g/L), regardless of whether they
were upgradient, downgradient, or on the well pad. This indicates that DRO detections were likely from
a naturally occurring source and would be the background range for the Killdeer aquifer.

7.4.   Summary of Water Quality Results
Two study wells, NDGW07 and NDGW08, consistently differed from the historical background data and
unimpacted well data for chloride, calcium, magnesium, sodium and strontium. The major anion and
cation chemistry of NDGW07 and NDGW08 were different than the unimpacted wells. On a local scale
other parameters such as manganese were different from the  local historical wells and unimpacted
wells. The only detections of TBA were in NDGW07  and NDGW08. It appears likely that NDGW07 and
NDGW08 have been  impacted. The hydrology at the pad site would suggest that the Franchuk well
blowout is a likely source of the impacts. Further analysis of the potential impacts on NDGW07 and
NDGW08 are described in the next section.

8. Specific  Focus Topics - NDGW07 and  NDGW08

8.1.   Hydrology Results from this Study
Synchronous depths to water in site monitoring wells were measured before sampling. Potentiometric
surface maps were prepared using the relative reference elevations and depth-to-water measurements
obtained on July 18, 2011 and October 17, 2011 (Table 8). Figure 12 illustrates the southerly ground
water flow direction on July 18, 2011 and a similar ground water flow direction during October 2011
(ground water flow direction is perpendicular to the hydraulic gradient).  This is similar to information in
a report that was provided to EPA by the state of North Dakota (Terracon, 2013).

8.2.   Brine as a Potential Source of Contamination
The elevated SpC and chloride concentrations found in NDGW07 and NDGW08 would suggest that brine
intrusion may be responsible.  The brine signature suggested in NDGW07 and NDGW08 is further
demonstrated by brine differentiation plots (Figure 13 and Figure 14; Hounslow 1995). Brine
differentiation plots can be used to screen samples for the potential brine impacts, but it should be
noted that not all of the elements used are conservative species (calcium, sodium and sulfate) and may
be subject to other chemical processes such as cation exchange and precipitations reactions. On
Figures 13 and 14, the red area is where Hounslow (1995) would predict brines to plot out, and the blue
area would be where brines would be expected to plot based on the UGSS produced water data base
(2002) for the Williston Basin. As can be seen in Figure 13, the produced water data for the formations
in Dunn County have some differences and not all the brines would plot in the region predicted by
Hounslow (1995). Figure 14 demonstrates that the unimpacted study wells do not plot in the regions
expected for potentially brine-impacted water, whereas  most of the samples taken for NDGW07 and
NDGW08 do plot in the regions expected for brine-impacted water.  (Samples for NDGW07 and
NDGW08 that do not plot in this region are discussed below in the "Time Trends" section.)

   Plots of TDS versus the ratio of chloride to the sum of anions (Cl/Zanions) have been suggested as a
means of distinguishing water  that is derived from  precipitation, water-rock interactions,  and water
derived from brine sources (Hounslow, 1995). Such a plot for the  Killdeer  study is shown in Figure 15.
From this plot it can be seen that the unimpacted wells  all plot in the cyan-colored field, which suggests
                                            48

that the water from these wells is derived from water-rock interactions, as would be expected.
NDGW07 and NDGW08 appear to have water that is of brine origin at times and at other times appears
to be similar to water derived from water-rock interactions. (Samples for NDGW07 and  NDGW08 that
plot outside the brine field are discussed below in the "Time Trends" section.)

Figure 16 shows plots of log chloride plotted against calcium, magnesium, and strontium and a plot of
log sodium/chloride versus log calcium/chloride. These plots indicate that for NDGW07  and NDGW08,
the data lie between the formation waters and the unimpacted wells. This is similar to what Stoessell
(1997) found when he plotted chloride against sodium, iodide, calcium, potassium, magnesium, and
strontium in Louisiana. In all cases the monitoring well concentrations in this study were between the
background concentrations and the Wilcox or Sparta brine data (Stoessell, 1997). Stoessell (1997) used
this as one line of evidence that the monitoring wells had been impacted by brine.

Plots of SpC versus a parameter can also be used to identify water that is potentially impacted by brines.
Figure 17 shows SpC plotted against chloride, bicarbonate, magnesium, and sodium. Again, the data in
Figure 17 for NDGW07 and NDGW08 are intermediate to the unimpacted wells and formation brines
that could potentially impact NDGW07 and NDGW08.  This is consistent with the water in NDGW07 and
NDGW08 potentially being a mixture of formation water and water from the Killdeer aquifer.  Panno et
al. (2006) used plots of SpC against chloride to help distinguish between pristine ground water and
ground water that has been affected by road salt.

Iodide also can be used to indicate waters that are potentially impacted by brines (Howard and Beck,
1993; Stoessell, 1997; Panno et al.,  2006; Harkness et al., 2015).  Iodide was measured only during the
final sampling round in this case study and was not detected in any of the unimpacted wells. However,
iodide was detected in both NDGW07 and NDGW08, above the quantification limit. Figure 18 shows a
plot of log chloride concentration versus log iodide concentrations.  Because the unimpacted wells had
no detectable iodide, the point on this plot representing the unimpacted wells is one-half the MDL for
iodide and the one-half the median chloride concentration.  NDGW07 and NDGW08 plot between the
unimpacted wells and that of the formation  brines (Figure 18). This also points to formation brine as the
source of impacts on NDGW07 and NDGW08. Road salt  could  also be a potential source of the impacts
observed and is discussed below in the "Source Delineation" section.

Lithium has also been suggested as a potential indicator  of brine impacts on ground water (Fontes and
Matray, 1993a; Fontes and Matray, 1993b; Bottomley et al., 2003; Hancini and Oelkers, 2011).  Lithium
was only analyzed in the final round of sampling. As is shown on Figure 19, the impacted wells fall
between the unimpacted wells and the formation brine data. This would also indicate the potential
source for the impacts seen in NDGW07 and NDGW08 are from a brine source.

8.3.   Time Trends
Changes in concentrations of a parameter with time can  indicate transport of contaminant in an aquifer
(Perez Guerrero et al., 2010; Olayiwola et al., 2013; Perez Guerrero et al.,  2013). Figure 20 shows the
changes in chloride concentrations  over time. (Time zero is the date of the Franchuk well blowout.) Also
shown  in Figure 20 are data provided by the state to EPA (dashed lines). The state collected data before
EPA sampling and more frequently. In general, the concentrations of chloride in the state data agree
with EPA chloride data when split sampling was performed.  Chloride concentrations in the unimpacted
wells were fairly consistent, and there was very little difference in concentrations of chloride in the
                                              53

unimpacted wells, as indicated by the yellow shaded areas. For NDGW07 and NDGW08, chloride
concentrations increased significantly from background, peaked, and then steadily decreased with time,
approaching background concentrations by the end of the study. The chloride peak in well NDGW08,
which is closest to the Franchuk well (approximately 4.5 m), arrived earlier than the chloride peak in
NDGW07 (approximately 12.8 m from the Franchuk well [see Figure  20]). The chloride peak at NDGW08
is much narrower than at NDGW07, and at NDGW08, peak chloride concentration is higher than at
NDGW07. This is likely due to dispersion of chloride during transport. As the chloride moves from its
source, it gradually spreads out three-dimensionally, which would cause a reduction in the
concentration of chloride at a given monitoring point further down gradient. In addition, dispersion
would cause the chloride plume to become spatially bigger, thus increasing the time it would take to
move past a point farther away from the source.  Similar relationships were exhibited by other inorganic
parameters. These examples would be consistent with a plume moving through the Killdeer aquifer
(Perez Guerrero et al., 2010; Olayiwola et al., 2013; Perez Guerrero et al., 2013).

In the case of tert-butyl alcohol (TBA), there were not enough data to plot, and the detection limits for
TBA were much higher in the state-commissioned data than in EPA data; and the state had one date
with  detectable TBA in their samples. Therefore, only data collected by EPA were used (Figure 21).
There is clearly a time trend in the TBA data from NDGW07 and  NDGW08 samples when compared with
the unimpacted well data. Samples from the unimpacted wells consistently indicated no detectable
TBA; however, there were always detectable concentrations of TBA in NDGW07 and NDGW08. The
concentration of TBA in NDGW08, the monitoring well closest to the Frankchuk well,  decreased with
time, with the peak concentration of TBA likely occurring between the first and second round of
sampling and the tail of the plume between the second and third rounds of sampling. NDGW07 is
farther downgradient of the Franchuk well. The peak concentration for NDGW07  likely occurred
around the second sampling round and then decreased before the third round of sampling. It is very
likely, based on these data that the TBA time trend represents a plume moving through the aquifer
(Perez Guerrero et al., 2010; Olayiwola et al., 2013; Perez Guerrero et al., 2013).

Because no additional samples have been taken since the October 2012 sampling round, it is not known
if NDGW07 or NDGW08 returned to unimpacted concentrations or how long it will take to reach
unimpacted conditions in these wells. However, using the conservative element chloride and the state-
provided data for NDGW08 (Figure 22), an estimate can be made.  As shown in Figure 22, the chloride
concentration in the tail of the peak for NDGW08 had seven points that could be used to estimate how
long  it would take for the water in NDGW08 to reach the secondary maximum  contaminant level (SMCL)
for chloride, mean and median unimpacted concentration of chloride using data from the  unimpacted
wells. First it is important to point out that the tail of the NDGW08 chloride peak is similar to a first
order kinetic (exponential) decay relationship.  Therefore,  a pseudo-first order kinetic decay model was
applied to the data collected for chloride.  Figure 22A is a plot of time versus the natural log of the
chloride concentration and, as can be seen, this is a roughly linear relationship with an r2= 0.985, which
means that a pseudo-first order kinetic decay model would be appropriate. Applying this model to the
actual data is shown in Figure 22B, and as can be seen the model fits the  actual data fairly well.  The
model was used to estimate the time it would take to reach the chloride SMCL (738 days), the mean
unimpacted chloride concentration (1,246 days), and the median unimpacted chloride concentration
(1,433 days). Because of the lack of data points after the peak in NDGW07 the same analysis cannot be
performed.

8.4.   Source of the Brine

8.4.1.  Out-of-Zone Fracturing
Research into out-of-zone hydraulic fracturing of the Bakken formation indicated that a large number of
wells contain water that is external to the Bakken Zone (Arkadakshiy and Rostron, 2012; Peterman et al.,
2012; Arkadakshiy and Rostron, 2013). Out-of-zone hydraulic fracturing is defined as the propagation of
fractures outside the production zone into adjacent formations (Arkadakshiy and Rostron, 2013). The
co-produced water comes from the adjacent, saturated carbonate aquifers (Arkadakshiy and Rostron,
2012; Peterman et al., 2012; Arkadakshiy and Rostron, 2013). Arkadakshiy and Rostron (2013) found up
to 70% of the Bakken wells contained external water. The Bakken wells that contained external water
were found to all contain water from the Mississippian Lodgepole formation (part of the Madison
Group). Water from the underlying Birdbear/Nisku zone was detected in a small number of these
wells—6 out of 358 wells (Arkadakshiy and  Rostron, 2013). The average volume of external water was
34%, and the external water volume ranged from 10% to 100% (Arkadakshiy and Rostron, 2013).

Based on this information it appears that any analysis of sources of brine impacts should also include
analysis of other formations  (see Figure 23). Based on the above discussion on out-of-zone fracturing
and the information presented in Figure 23, the likely formations for out-of-zone fracturing would be
the Madison group, the Three Forks formation, and the Jefferson Group (Birdbear and Duperow
Formations).  Data were obtained for these formations as well as the Interlake, Red  River, and Tyler
Formations, also in Dunn County, for the source delineation analysis, which will be discussed in the next
section.

8.4.2.  Source Delineation
Techniques such as the use of correlation plots and ratios can be used to indicate or fingerprint brines
(Leonard and Ward, 1962; Howard  and Beck,  1993; Stoessell, 1997; Davis et al., 1998; Vengosh and
Pankratov, 1998; Hudak and Wachal, 2001; Hudak, 2003; Panno et al., 2006; Freeman, 2007; Katz et al.,
2011; Hudak, 2012; Harkness et al., 2015).

Log chloride versus log calcium, log magnesium, and log strontium plots as well as log sodium/chloride
versus log calcium/chloride plots are shown on Figure 24. Also shown on Figure 24 are trend lines
representing the 1:1 dilution between the median unimpacted well concentrations and the median
concentrations of the various brine formation waters.  With the exception of the Three Forks/ Sanish
trend line in the log chloride versus log magnesium (Figure 24B), these trends are very similar in all other
cases, with slight differences in slopes. The data from the impacted wells, NDGW07 and NDGW08,
however, do not fall on the trend lines for calcium and strontium and have lower cation concentrations
than would be predicted by a simple 1:1 dilution of formation water with the unimpacted wells (Figures
24A and 24C). This is not unexpected because the cations calcium and strontium are not conservative
species. This means that other geochemical processes (precipitation, cation exchange, complexation,
etc.) can alter the concentrations of the cations during transport in the aquifer and/or to the aquifer.
For magnesium (Figure 24B)  many data points for the impacted well NDGW08 and NDGW07 fall on  or
very close to the 1:1 trend lines for deep formation brines, with the exception of the Three Forks/ Sanish
formation.  NDGW07 and NDGW08 data are similar to the formation waters when plotting log
sodium/chloride versus log calcium/chloride (Figure 24D). The plots in Figure 24 are useful in suggesting
                                              62

that formation brines are a potential source of the impacts on NDGW07 and NDGW08 but are not useful
in determining which formation brines would be the source of the observed impacts.

The chloride to bromide ratio (CI/Br) can also be useful in differentiating sources of water. Panno et al.
(2006) concluded that ratios of halides plotted against their own concentrations can distinguish
between sources of chloride- contaminated water.  In addition,  Freeman (2007) was able to use CI/Br to
differentiate shallow ground water with elevated chloride concentrations between ground water that
result from mixing salt-dissolution and ground water that has mixed with formation brines.

Figure 25 is a plot of log chloride versus log CI/Br. The CI/Br in unimpacted wells are much lower than
those of the impacted wells (NDGW07 and  NDGW08) and formation brines. The CI/Br for NDGW07 and
NDGWOSare in the same range as those of the brine formations. Both NDGW07and NDGW08 CI/Br
plot between the mixing trends of the formation brines and unimpacted wells. The percentage of
formation brines (up to 5%) needed to change the unimpacted Killdeer water along the mixing curves is
indicated in Figure 26. As shown, NDGW07 and NDGW08 only need between 0.1 to 1 % of any of the
formation brines to be mixed with the unimpacted Killdeer aquifer water to explain the changes
observed in NDGW07 and  NDGW08. The CI/Br found in NDGW07 and NDGW08 are consistent with
impacts as the result of mixing of formation brine water with  Killdeer aquifer water.

Research has shown that lithium becomes more concentrated in brines, oil field brines, and saline lakes
(Fontes and Matray, 1993a; Fontes and Matray, 1993b; Bottomley et al., 2003; Hancini and Oelkers,
2011). Fontes and Matray (1993a) inferred that lithium was a conservative species during sea water
concentration, and lithium does not appear to be affected by reactions with solid salts and interbedded
sediments. For these reasons lithium would represent a good tracer for the successive mixings in
formation brines (Fontes and Matray, 1993a). Similarly, in saline lakes, lithium tends to be conserved
during evaporation (Hacini and Oelkers, 2011).  In brines associated with oil fields near Paris, France,
Fontes and Matray (1993b) found that lithium concentrations in the brine were much higher than one
would predict for sea  water evaporation and this was likely caused by digenetic contributions
(alterations in rock minerals during and after rock formation)  for an extremely evolved brine. Bottomley
et al. (2003) found that lithium is primarily of marine origin because lithium is a relatively minor
component in crustal  rocks in non-marine origin rocks. These authors were able to use lithium to show
deep brine waters mixing with near surface waters derived from the interactions with host rocks
(Bottomley et al., 2003). Therefore, lithium may be a useful indicator of water impacted by brines.

The log sodium/lithium ratios (Na/Li) were plotted against the log sodium concentrations for the study
data and the formation brine waters (Figure 27). It is important to note that lithium data were collected
only during the final round of sampling (October 2012), and it is not  known how or if the Na/Li may have
changed prior to this sampling round.  NDGW07 and NDGW08 lie between that of the unimpacted wells
and the other formation brines and fall on the mixing lines for the Bakken, Madison, and Birdbear
formations. This would be consistent with the Franchuk well  having had out-of-zone fracturing as was
described in Arkadakshiy and Rostron (2012, 2013). Both the Birdbear and especially the Madison
formation were implicated as sources of water in Bakken wells by these researchers (Arkadakshiy and
Rostron, 2012, 2013; Peterman et al., 2012). As was done with the CI/Br, the percentage of formation
brines (up to 5%) needed to change the unimpacted Killdeer water along the mixing curves was plotted
and is shown in Figure 28.  Again, NDGW07 and NDGW08 only need between 0.1 to 1 % of any of the
                                             65

formation brines to be mixed with the unimpacted Killdeer aquifer water to explain the changes
observed in NDGW07 and NDGW08.

Several researchers have suggested the use of iodide as a potential indicator to distinguish between
sources of ground water (Lloyd et al., 1982; Howard and Beck, 1993; Stoessell, 1997; Panno et al., 2006).
Lloyd et al. (1982) found that the presence of iodide in ground water indicates sea water intrusion into
aquifers along English estuaries and can be used to distinguish ground waters in limestones and shaley
gypsiferous rocks as well as to indicate residence time. Iodide has also been found to be useful in
differentiating waters impacted by road salts and saline bed rock waters even when these waters are
not distinguishable  using major ions (Howard and Beck, 1993).  Finally, Stoessell (1997) was able to show
that iodide was useful in identifying ground water that had been  potentially impacted by oil field  brines.

A plot of log chloride versus log Cl/l ratios is shown in Figure 29; again, iodide was collected only during
the final round of sampling  (October 2012). It is not known how or if the Cl/l changed before this
sampling round. Figure  29 shows that the Cl/l in NDGW07 and NDGW08 is lower than the unimpacted
wells and falls outside the mixing trends between the unimpacted wells and the formation brines. Also,
it can be seen that,  based on the  spread of the Madison formation brine data, NDGW07 and NDGW08
could still potentially fall within the mixing envelope (defined by the area between the upper and lower
limit lines for the unimpacted Killdeer aquifer and the brine formation) of the Madison formation brine
waters. Therefore,  mixing envelopes were prepared for the Bakken formation brines and the Madison
formation brines (Figure 30). NDGW07 and NDGW08 do fall within the mixing envelopes of the Madison
formation brines (Figure 30B), whereas NDGW07 and NDGW08 do not fall within the mixing envelopes
of the Bakken brines (Figures 30A). This finding suggests that the Madison formation brine is the source
of the brine impact  on NDGW07 and NDGW08.

Figure 31 shows a plot of the reciprocal strontium concentration  versus 87Sr/86Sr ratio for the study data,
the Bakken formation, and the  Madison formation (Ratcliffe member). NDGW07 and NDGW08 also plot
between the unimpacted and brine formations.  The unimpacted wells and NDGW07 and NDGW08 have
an 87Sr/86Sr isotopic composition  similar to the Madison formation but are different than the 87Sr/86Sr
isotopic composition of the Bakken formation. Also indicated on  Figure 31 are arrows showing changes
in NDGW07 and NDGW08 between the October 2011 and October 2012 sampling rounds. The changes
are primarily associated with the  strontium concentrations.

Time trends for the  study data  and mixing curves between the unimpacted wells and the brine
formations (Bakken and Madison) were used to better understand the source of the brine impacts seen
in NDGW07 and NDGW08 (Figures 32 and 33). Both the Bakken and Madison formation waters could
explain the apparent 87Sr/86Sr isotopic signature of NDGW07 and  NDGW08 (Figure 31). Figure 32 further
investigates the  changes in  strontium isotopic composition and concentration between the October
2011 and October 2012  sampling rounds. Figure 32 shows that there was a very slight decrease in the
strontium isotopic composition between the two sampling rounds.  Furthermore, the isotopic
composition trends of the unimpacted wells and those of NDGW07 and NDGW08 are similar. This
suggests that the changes in strontium isotopic composition are likely part of the natural variations in
the Killdeer aquifer  at the Franchuk well site.  NDGW07 and NDGW08 strontium concentrations trends
(Figure 32) are different than those of the unimpacted wells (except NDGW06).  The strontium
concentrations in the unimpacted wells (except NDGW06) did not appear to vary between the October
2011 and October 2012  sampling rounds. NDGW07 and NDGW08 both show decreasing strontium
                                             70

concentration between the October 2011 and October 2012 sampling rounds.  NDGW06 shows a slight
increasing strontium concentration during this time interval. However, using the data collected as part
of this study, it is not known whether the Sr concentration in NDGW06 would constitute an upward
trend or if this is the result of an anomalous data point.

the mixing curves was plotted and is shown in Figure 33.  Again, NDGW07 and NDGW08 only need
between 0.1 to 1 % of any of the formation brines to be mixed with the unimpacted Killdeer aquifer
water to explain the changes observed in NDGW07 and NDGW08. Based on mixing models alone, one
cannot distinguish between the strontium isotopic fingerprint of the Bakken formation brine or the
Madison formation brine.

Combining the 87Sr/86Sr isotopic ratios and concentration time trends with a mixing analysis (Figure 34)
can potentially be used to delineate a source of the brine observed in  NDGW07 and NDGW08.  If the
Bakken formation was the source of the brine, one would expect the 87Sr/86Sr ratio in NDGW07 and
NDGW08 to decrease with time, which was not observed. Rather the 87Sr/86Sr ratio remained relatively
constant with time. This relatively constant 87Sr/86Sr ratio over the course of the study in NDGW07 and
NDGW08 suggests that the Madison formation would be the brine source. The reason for this is that
based on the mixing model for the Madison formation, only the strontium concentration would be
required to change and not the 87Sr/86Sr isotopic ratio, which was observed  in the study. As was stated
earlier, Arkadakshiy and Rostron (2013) found that many Bakken wells often had  out-of-zone fractures,
so this could potentially have happened at the Franchuk well and would explain why the impacts on
NDGW07 and NDGW08 did not have an isotopic signature like the Bakken formation wells.

Stable isotopes of water (618O and 62H) were collected as part of this study and compared with data for
formation waters produced in Dunn County, North Dakota (Figure 35). In Figure 35A one can see that
the study data mostly lie below the Global Meteoric Water Line  (GMWL) (Craig, 1961), and the Local
Meteoric Water Line (LMWL) (Kendall and Coplen, 2001) fits the study data better. With the exception
of the Madison formation, all other formation waters show considerable differences between the study
samples and the formation water isotopic signature, and  NDGW07 and NDGW08 do not fit the mixing
trends. The water isotopic signature of the Madison formation overlaps the study isotopic water
signature but is slightly shifted to lower values of 618O and 62H (Figure 35).  If one looks at the study
portion of this plot in detail (Figure 35B) it appears that the majority of the unimpacted wells fall on the
LMWL. This is not unexpected because the main source of water in the Killdeer aquifer is believed to be
recharge from precipitation (Klausing, 1979; Murphy, 2001). A closer  look also reveals that the isotopic
composition of the water from NDGW07 and NDGW08 initially are above the LMWL and then move
below the LMWL, as indicated by the arrows in Figure 35B. The  majority of the unimpacted wells are
somewhat shifted from NDGW07 and NDGW08 to higher values of 618O and 62H. In addition, it appears
that NDGW07 and NDGW08 plot within the isotopic signature of the Madison formation (Figure 35B).
Warner et al. (2012) points out that 618O and 62H are not sensitive tracers for mixing of two sources of
water.  Therefore, stable isotopes of water are not sensitive enough to determine if the Madison
formation is the source of the changes in water quality seen in NDGW07 and NDGW08. What Figure
35B does point out is that the other formation waters are not the source of the observed impacts in
NDGW07 and NDGW08, based on water isotopic signatures.

Retrospective Case Study in Killdeer, North Dakota                                               May 2015


An impact due to road salt applied to the highway just to the south of the Franchuk well pad would be
very unlikely because the ground water flow direction would have to be to the north, in contrast to the
south, based on information from this study. Based on the data from the other unimpacted monitoring
wells, impacts caused by surrounding oil and gas activities or land use practices or industrial activities
are also unlikely because one would expect there to be residual chemical  signature of an impact in those
unimpacted monitoring wells. These unimpacted monitoring wells were not statistically different than
the historical background water quality of the Killdeer aquifer. Based on this study, the blowout at the
Franchuk well is a probable cause of the impact seen in NDGW07 and NDGW08.

The preceding analysis of potential sources indicates that the source of the brine impact on NDGW07
and NDGW08 is consistent with mixing of Madison formation brines with  Killdeer aquifer water.
Although the Franchuk well was drilled into the Bakken formation, others have pointed out that out-of-
zone fracturing is a common problem with Bakken wells (Arkadakshiy and Rostron, 2012; 2013).
Furthermore, Aradakshiy and Rostron (2013) have pointed out that when out-of-zone fracturing occurs,
many Bakken wells have a Madison-like produced water. This could explain the influence of Madison
formation water in NDGW07 and NDGW08.

8.5.   Tert-Butyl Alcohol  (TBA)
Tert-butyl alcohol was consistently and selectively present in NDGW07 and NDGW08 throughout the
course of the study (Appendix B, Table B4). The potential sources for the  observed TBA are fluids
released during the Franchuk well blowout event and potential releases of contamination (see Appendix
C) related to gasoline spills and leaking USTs.

Methyl tert-butyl ether (MTBE) can be present in gasoline and can degrade to TBA (Wilson  et al., 2005).
However, gasoline as the source of TBA is unlikely because methyl tert-butyl ether was not detected nor
was any other components of gasoline or the daughter products of gasoline detected in upgradient
wells or other monitoring wells.

Although TBA was not listed as a component of the hydraulic fracturing fluid used at the Franchuk well,
it is known to be a daughter product of tert-butyl hydroperoxide, which was used (see Table 1) (Hiatt et
al.,  1964; Martynova et al., 2001; Chen, 2005; Stepovik and Potkina, 2013). Hiatt et al. (1964) found that
unreacted tert-butyl hydroperoxide [(CH3)3COOH] would form TBA [(CH3)3COH] and oxygen (O2) by the
following mechanism:

                              (CH3)3COOH ^ (CH3)3CO • + • OH

                    (CH3)3CO • +(CH3)3COOH ^ (CH3)3COH + (CH3)3COO •

                              2(CH3)3COO -^ 02 + 2(CH3)3CO -.

Others also have proposed mechanisms for the degradation of tert-butyl hydroperoxide in the presence
of metal cations (Mn+) and organic compounds (R-H) (Martynova et al., 2001; Chen, 2005; Stepovik and
Potkina, 2013):

                       (CH3)3COOH + Mn+ ^ (CH3)3CO • +OH~ + Mn+1

                            (CH3)3CO • +R - H ^ (CH3)3COH + R -.
                                             79

Retrospective Case Study in Killdeer, North Dakota                                                May 2015


Either of these mechanisms is a plausible explanation of the TBA detected in NDGW07 and NDGW08.
Because TBA was not detected in any other monitoring wells or the upgradient wells it is unlikely that
the source of TBA was any other oil and gas activities in the area.

8.6.   Sulfate
Sulfate concentrations in the Killdeer aquifer commonly exceeded the secondary maximum contaminant
level (SMCL) for sulfate. This was true for data collected as part of the study and historical databases
and also was reported by Battelle (2013). Gypsum is a common source of sulfate as well as a sink for
sulfate in the environment (Hounslow, 1995). Figure 36 is a plot showing the relationship of sulfate
concentrations to the gypsum saturation index.  Figure 36 was constructed using gypsum saturation
indices calculated using Geochemist Workbench. Forty-one of the 42 study samples collected (98%) had
charge balances < 5%. One sample, NDGW05-102011, had a charge balance of 5.2% and was still
included in Figure 36 because this would potentially cause only a minor error in the calculation of the
gypsum saturation index.

As is shown in Figure 36, even when the sulfate concentrations are greater than the SMCL, the gypsum
saturation index would indicate that the water in the Killdeer aquifer is under-saturated with respect to
gypsum. This means that the water can continue to have higher sulfate concentrations until the
saturation index reaches 0.  According to the soil survey of Dunn County, many of the soils have salt
crystals/ layers, gypsum crystals/layers, and carbonate crystals/layers in the sub soil (USDA, 2013). All
these are potential sources for sulfate in the Killdeer aquifer. The primary recharge to the Killdeer
aquifer is through recharge from precipitation, and as the precipitation leaches through the soil to the
aquifer it is likely to come into contact with gypsum and would dissolve some of the gypsum or selenite,
releasing sulfate into the water.  Therefore, the high sulfate in the Killdeer aquifer is naturally occurring
and most likely not related to any anthropogenic sources.

gypsum. Saturation index equal to zero indicates that the sulfate concentrations in the water is in equilibrium with
solid gypsum, saturation index> 1 indicates the sulfate concentrations of water are oversaturated with respect to
gypsum, and saturation index <1 indicates sulfate concentrations in the water are under-saturated with respect to
gypsum. The black triangles = study data and the red dashed line in the sulfate secondary MCL  As is shown, all

9. Summary of Case Study Results
The Killdeer Retrospective Case Study was conducted near the city of Killdeer, in Dunn County, North
Dakota. The area was and is currently part of the Bakken Shale development. This retrospective case
study contrasts with the other EPA retrospective case studies in that the study was done in an area
where a known release occurred during the hydraulic fracturing process.  The known release was the
result of a blowout that occurred in the Franchuk 44-20 SWH well in September 2010, during the fifth
stage of a 23-stage hydraulic fracture (Jacob, 2011). The blowout resulted in the release of hydraulic
fracturing fluids, oil, and flowback water onto the land surface and possibly into the Killdeer aquifer.
The blowout resulted when an inner string of casing ruptured due to over-pressurization during the
hydraulic fracturing process. The blowout prompted state action, which led to the installation of
monitoring wells on and around the well pad and monitoring of nearby domestic wells, water supply
wells, and municipal wells for the city of Killdeer. A comprehensive evaluation of the ground water
around the well pad was conducted as part of this study to determine the level of impact and to account
for all potential sources of contamination. Two potential pathways for contamination of the Killdeer
aquifer from the blowout were considered: (1) direct release from the Franchuk wellbore  laterally into
the Killdeer aquifer and (2) indirect contamination from surface infiltration of released fluids down into
the Killdeer aquifer.

The initial screening analysis of the study data identified two wells,  NDGW07 and NDGW08, as having
different water quality than the other study wells. NDGW07 and NDGW08 showed differences in the
majority of parameters such as chloride, calcium, magnesium, sodium, and strontium. The study wells,
excluding NDGW07, NDGW08, and NDGW09, were then compared  with historical data obtained for the
Killdeer aquifer. NDGW09 was not compared with historical data from the Killdeer aquifer because it
was screened partly or entirely within the Sentinel Butte aquifer.

All study wells, except the wells noted above, were compared with  historical data from wells within 3
miles of the Franchuk 44-20SHW well (Franchuk well). Analysis of the historical data analysis indicated
that all study wells except NDGW07, NDGW08, and NDGW09  were  not significantly different than the
historical data from the Killdeer aquifer. The October 2012 data for NDGW06 had  chloride
concentrations higher than what was expected.  A Q-test was performed  on NDGW06, and it was
determined that the October 2012 NDGW06 was indeed an outlier with respect to chloride but was not
an outlier for other parameters. Even though chloride concentrations in NDGW06 for the October 2012
sampling round were higher than would be expected, the inclusion  of this point into the statistical
analysis did not change the fact that there were no statistical differences  between the study wells
(except wells already noted) and the historical data.  Based on this comparison with historical data, the
study wells, excluding NDGW07, NDGW08 and NDGW09, were considered unimpacted wells. A
summary of potential ground water impacts is provided in Table 9.

There were no detectable concentrations of propane or butane in any of the study samples collected.
Ethane was detected in only one sample during the study; the detected concentration, 0.0044 mg/L, is
approximately two times the QL (0.0028 mg/L) for ethane.  Methane was detected in 24%  of the study
samples, with a maximum observed concentration of 0.0253 mg/L.  The methane concentrations
detected in the study were compared with background methane concentrations discussed in a report on
field screening for shallow gases in North Dakota (Anderson et al., 2010).  This comparison indicated
                                             82

that the methane concentrations observed during the study were consistent with background methane
concentrations in the Killdeer aquifer (0.0149 to 0.3978 mg/L).

Thirty-eight VOC compounds were analyzed for during the study, and at least one was detected in 15%
of the samples.  The VOCs detected were acetone, toluene, m+p-xylene, o-xylene, 1,2,4-
trimethylbenzene, and 1,2,3-trimethylbenzene (2% of the samples); benzene (7% of the samples); and
tert-butyl alcohol (TBA) (15% of the samples). With the exception of TBA, all VOC compounds detected
in the study wells could be related to a potential source other than hydraulic fracturing. TBA, however,
was consistently detected in NDGW07 and NDGW08, but not in the unimpacted wells.  The
concentrations of TBA observed in NDGW07 and NDGW08 was consistent with a plume moving through
these wells. In addition, TBA is a known daughter product of the degradation of MTBE  and tert-butyl
hydroperoxide.  Degradation of MTBE is not a likely source, because MTBE was not detected in these
wells nor were other compounds one would expect to be associated with MTBE, such as gasoline
constituents.  However, the TBA was consistent with the degradation of tert-butyl hydroperoxide, a
component used in the hydraulic fracturing fluid at the time of the blowout. So it is unlikely that sources
other than the blow out were responsible for the observed TBA in NDGW07 and NDGW08. Although
benzene was detected in NDGW07 during the October 2012 sampling round, no potential source of this
benzene could be determined, because benzene was not detected in other wells or during other
sampling rounds.

Similar to the VOC data, there were limited detections of other organic compounds in the study data,
and it was not possible to link these compounds to any source of contamination. No glycols were
                                             84

detected in the study wells during the study. The detection frequency for low-molecular-weight acids
was 31%, and the detections were for formate (10% of samples) and acetate (31% of the samples).
Finally, 84 SVOCs were analyzed for and the detection frequency was 34%. The SVOCs detected during
the study were 2-butoxyethanol, dimethyl phthalate (2% of the samples), bis-(2-ethylhexyl) phthalate
(17% of the samples), and bis-(2-ethylhexyl) adipate (34% of the samples).

The limited hydrological investigations at the Franchuk well pad were able to show a general ground
water flow direction. The temporal fluctuations in the hydraulic gradients on the pad appear to be
significant. Although there appeared to be significant fluctuations in the hydraulic gradients, the ground
water always had a southerly component to the ground water flow.  Based on this analysis brine
contamination from road salt could be eliminated as a  potential cause of the observed changes to water
quality in NDGW07 and NDGW08. For road salt to impact NDGW07 and NDGW08 the flow direction
would have to have a northerly component, which was not observed.

Time-trend analysis revealed that the data collected over time was indicative of transport of
contaminants through  NDGW07 and NDGW08. In addition, the peak concentrations in the parameters
examined were first observed in NDGW08 and then observed in NDGW07 at a later date.  Chloride
concentration data for the decay portion of the time series plots were found to follow pseudo-first order
kinetics, and a kinetic model could be developed to estimate how long it would take for chloride to
attain unimpacted chloride concentrations found in the Killdeer aquifer.  Based on this analysis it would
take approximately 1,246 days to attain the mean unimpacted chloride concentration and 1,433 days to
attain the median unimpacted chloride concentration at the Killdeer site.

Other nearby oil and gas activities, land use practices, or industrial sources as causes of the observed
impacts on NDGW07 and NDGW08 are not likely. The monitoring well network installed around the
Franchuk well pad (except NDGW07 and NDGW08) would have detected a plume, or there would be
residual changes to ground water quality in these monitoring  wells if the source of the contamination
were off-site. No plumes or residual changes to ground water quality in monitoring wells other than
NDGW07 and NDGW08 were observed. Therefore, the only source that would be consistent with the
impacts observed in NDGW07 and NDGW08 would be the blow out that occurred on this pad.

Further analysis of unimpacted water with NDGW07 and NDGW08 indicated that the impacts on
NDGW07 and NDGW08 were consistent with impacts caused  by the mixing of briny water with water
from the  Killdeer aquifer. All methodologies used to delineate the source indicated that the mixing of
unimpacted Killdeer aquifer water with deep formation brines would be consistent with the  impacts
observed in NDGW07 and NDGW08. The use of sodium to lithium ratios (Na/Li), chloride to  iodide
ratios Cl/l and isotopic  analysis indicated the most likely cause of the impacts observed in NDGW07 and
NDGW08 was a brine with a signature of the Madison formation. Although a Madison formation brine
signature was not expected as the result of the impact from a Bakken formation well such as the
Franchuk well, the literature does support this possibility because out-of-zone fracturing has been
demonstrated for some Bakken wells.

Many of the study samples as well as the historical data indicated that sulfate exceeded its secondary
maximum contaminant level (SMCL). Analysis  of the data and the geology of Dunn County indicate that
sulfate concentrations  in the Killdeer aquifer are consistent with naturally occurring sources  such as
gypsum and selenite in the soils of Dunn County. It is unlikely that any anthropogenic impacts would
cause the high sulfate concentrations observed in the Killdeer aquifer.

Retrospective Case Study in Killdeer, North Dakota                                                May 2015


Two of the 16 wells sampled in this investigation, NDGW07 and NDGW08, exhibited evidence of impacts
from the blowout of the Franchuk well.  The impacts on NDGW07 and NDGW08 are consistent with
impacts from deep formation brine.  The detections of TBA in NDGW07 and NDGW08 are another
important factor in determining the causes of impacts on these wells. The potential sources of
contamination at the Franchuk well site were related to nearby oil and gas exploration, leaking USTs,
land use practices, road salt, and the blowout of the Franchuk well. Other potential sources of
contamination could be ruled out based on hydrology and the lack of residual signatures of impacts in
nearby monitoring wells.  The Franchuk well blowout would explain the impacts on NDGW07 and
NDGW08, because the fingerprint of the water is what would be expected as the result of mixing of
deep brine waters, specifically the Madison Formation water, with the Killdeer aquifer waters if out-of-
zone fracturing occurred. However, the exact mechanism/pathway could not be determined.

Key observations or findings from this study are listed below.

    •   Thirty-eight VOCs were analyzed  for during the  study, and one or  more of these VOCs were
        identified in 15% of the study samples.  With  the exception of TBA, all VOCs  detected in the
        study wells could be related to a potential source other than hydraulic fracturing.

    •    No glycols were detected in the study wells during the study.

    •    Eighty-four SVOCs were analyzed for during the study, and one or more of these SVOCs were
        identified in 34% of the study samples. The SVOC compounds detected in the study wells could
        be related to a potential source other than  hydraulic fracturing.

    •    Methane was detected in 24% of the study samples, with a maximum observed concentration of
        0.0253  mg/L   Methane concentrations  observed during the study  were consistent  with
        background methane concentrations in the Killdeer aquifer (0.0149 to 0.3978 mg/L).

    •   Thirty-eight percent of the study samples and  the  historical  samples indicated that sulfate
        exceeded its secondary maximum contaminant level (SMCL).  The sulfate concentrations in the
        Killdeer aquifer are consistent with naturally occurring sources  such as gypsum and selenite in
       the soils of Dunn  County.

    •   The data from all study wells except NDGW07, NDGW08, and NDGW09 (NDGW09 was screened
        or partly screened  in the Sentinel Butte aquifer) were  not significantly different from  the
        historical data from the Killdeer aquifer, and these wells were considered unimpacted.

    •   The study identified two wells, NDGW07 and NDGW08, that had water quality different from
       the other study wells and historical data.

           o  NDGW07 and NDGW08 showed differences  in the majority of parameters, including
              chloride,  calcium, magnesium, sodium, and strontium.

           o  Time-trend analysis revealed that the data collected were indicative  of  transport of
              contaminants through NDGW07 and NDGW08.

           o  TBA was  consistently detected in  NDGW07  and NDGW08, but not  in the unimpacted
              wells.   TBA concentrations  were  consistent with the degradation  of  tert-butyl
                                             86

              hydroperoxide,  a component  used  in the hydraulic fracturing fluid at the time of the
              blowout.

           o  The limited hydrogeological investigations at the Franchuk well pad were able to show a
              general ground  water flow direction. Although there appeared to be fluctuations in the
              hydraulic gradients, ground water always had a southerly flow component, which would
              be consistent with a plume moving from the Franchuk well towards the impacted wells.

           o  All methodologies used to delineate the source indicated that the mixing of unimpacted
              Killdeer aquifer  water with deep formation brines would  be consistent with the impacts
              observed in NDGW07 and NDGW08. The deep formation brine had the signature of the
              Madison formation.  A Madison Formation brine signature is consistent with literature
              that indicates out-of-zone fracturing has been observed in some Bakken wells.

    •   The only potential source consistent with the impacts observed in NDGW07 and NDGW08 would
       be the blow out that occurred on this pad.

A.I.   Introduction
This section describes general quality assurance (QA) and results of quality control (QC) samples,
including discussion of chain of custody, holding times, blank results, field duplicate results, laboratory
QA/QC results, data usability, performance evaluation (PE) samples, Quality Assurance Project Plan
(QAPP) additions and deviations, field quality assurance/quality control (QA/QC), application of data
qualifiers, tentatively identified compounds (TICs),  Audits of Data Quality (ADQ), laboratory and field
Technical System Audits (TSA).

All reported data met project requirements unless otherwise indicated by application of data qualifiers.
In some cases, data were rejected as unusable and  not reported.

A.I.I. July 2011 Sampling Event
The sampling  and analytical activities for the July 2011 sampling event were conducted under a QAPP
titled  "Hydraulic Fracturing Retrospective Case Study, Bakken Shale, Killdeer and Dunn County, ND,"
revision 0, approved on  June 20, 2011. Deviations from this QAPP are described in Section A9.  Nine
monitoring wells, one municipal supply well, two supply wells, three domestic wells, and one state well
were sampled during this event. A total of 282 samples were collected and delivered to four
laboratories for analysis: Shaw Environmental, Ada, OK; EPA Office of Research and
Development/National Risk Management Research Laboratory (ORD/NRMRL), Ada OK; EPA Region 8,
Golden, CO; and EPA Region 3, Fort Meade, MD.  More than 215 analytes were measured per sampling
location.  Of the 282 samples collected, 90 samples (32%) were QC samples, including blanks, field
duplicates, matrix spikes, and matrix spike duplicates.

A.I.2. October 2011  Sampling Event
The October 2011 sampling and analytical activities were conducted under an approved QAPP,
"Hydraulic Fracturing Retrospective Case Study, Bakken Shale, Killdeer and Dunn County, ND," revision
1, approved August 29,  2011. Deviations from this QAPP are described in Section A9. Nine monitoring
wells, one municipal supply well, two supply wells, three domestic wells, and one state well were
sampled during this event.  A total of 336 samples were collected and delivered to six laboratories for
analysis:  Shaw Environmental, Ada, OK; EPA ORD/NRMRL, Ada OK; EPA Region 8, Golden, CO; EPA
Region 3, Fort Meade, MD; EPAORD/National Exposure Research Lab (NERL), Las Vegas, NV; and U.S.
Geological Survey (USGS) Laboratory, Denver, CO. More than 228 analytes were measured per sampling
location.  Of the 336 samples collected, 85 samples (25%) were QC samples, including blanks, field
duplicates, matrix spikes, and matrix spike duplicates.

A.1.3. October 2012  Sampling Event
The October 2012 sampling and analytical activities were conducted under an approved QAPP,
"Hydraulic Fracturing Retrospective Case Study, Bakken Shale, Killdeer and Dunn County, ND," revision
1, approved August 29,  2011. An addendum to the QAPP was prepared to document QC acceptance
criteria for analysis of samples for metals using a different laboratory from the one used on the previous
sampling events, "Hydraulic Fracturing Retrospective Case Study, Bakken Shale, Killdeer and Dunn
County: Analysis of Samples by the EPA Region VII Contract Laboratory for the October 2012 Sampling

Event, Revision 1 Addendum/' approved on February 25, 2013. Deviations from this QAPP are described
in Section A9. Nine monitoring wells and one state well were sampled during this event. A total of 255
samples were collected and delivered to six laboratories for analysis: Shaw Environmental, Ada, OK; EPA
ORD/NRMRL, Ada OK; EPA Region 8, Golden, CO; EPA ORD/NERL, Las Vegas, NV; Southwest Research
Institute Laboratory, San Antonio, TX; and USGS Laboratory, Denver, CO.  More than 230 analytes were
measured per sampling location.  Of the 255 samples, 76 samples (30%) were QC samples, including
blanks, field duplicates, matrix spikes, and matrix spike duplicates.

A final version of the QAPP titled  "Hydraulic Fracturing Retrospective Case Study, Bakken Shale, Killdeer
and Dunn County, ND," revision 2, was approved on December 13, 2013.

A.2.   Chain of Custody
Sample types, bottle types, sample preservation methods, analyte holding times, and laboratories
receiving samples are listed in Table Al. Samples collected in the field were packed on ice into ice
chests for shipment by overnight  delivery along with completed chain-of-custody (COC) documents and
temperature blank containers.  Samples were received by the laboratories in good condition, and all
temperature blanks were less than 6°C. There were no chain of custody issues that had an impact on
data quality.

A.3.   Holding Times
Holding times are the length of time a sample can be stored after collection and prior to analysis without
significantly affecting the analytical  results.  Holding times vary with the analyte, sample matrix, and
analytical methodology. Sample holding times  for the various analyses conducted  in this investigation
are listed in Table Al and range from seven days to six months. Generally, the estimated analyte
concentration for samples with holding time exceedances are biased low.

A.3.1.  July 2011 Sampling
All samples met holding times.

A.3.2.  October 2011 Sampling
Sample NDGW07 was re-analyzed for bromide  twelve days past its holding time. Sample result is
qualified with an "H" and could have a potential negative bias.

A.3.3.  October 2012 Sampling
All samples met holding times.

A.4.   Blank Samples Collected  During Sampling
An extensive series of blank samples were collected during all sampling events, including field blanks,
equipment blanks, and trip blanks (see Table A2). These QC samples were intended to test for possible
bias from potential sources of contamination during field sample collection, equipment cleaning, sample
bottle transportation to and from the field, and laboratory procedures. The same source water was
used for the preparation of all blank samples (Barnstead NANOpure Diamond UV water).  Field blanks
were collected to evaluate potential contamination from sample bottles and  environmental sources.

Appendix A QA/QC Summary, Retrospective Case Study in Killdeer, North Dakota                          May 2015

Equipment blanks were collected to determine whether cleaning procedures or sample equipment
(filters, fittings, tubing) potentially contributed to analyte detections. Trip blanks consisted of serum
bottles or volatile organic compound (VOC) vials filled with NANOpure water and sealed in the
laboratory. Trip blanks were used to evaluate whether VOCs and dissolved gas serum bottles were
contaminated during sample storage, sampling, or shipment to and from the field.  All other analyses
had associated field and equipment blanks (when needed), except for isotope ratio analyses, for which
no blank sampling schemes are appropriate. Sample bottle types, preservation, and holding times were
applied to blank samples in the same way as they were applied to field samples (see Table Al).

The following criteria were used to qualify samples with potential blank contamination. Sample
contamination is considered possible if analyte concentrations in blanks are above the method
quantitation limit (QL) and if the analyte is present in an associated field sample at a level <10 times the
concentration in the blank. In cases where both a sample and  its associated laboratory, equipment, or
field blank are between the method detection limit (MDL) and the QL, the sample results are reported
as 
-------
Appendix A QA/QC Summary, Retrospective Case Study in Killdeer, North Dakota                         May 2015

QL, therefore the sample was not impacted. The EPA Region 8 Laboratory analyzed the blanks samples
for GRO and DRO and found that the source water used to collect the field blank samples was
contaminated with cyclohexane.

A.4.2. October 2011 Sampling
All of the blanks collected for acetate analysis had concentrations of acetate higher than the QL (see
Table A7). With the exceptions of samples NDGW02-102011 and NDGW07-102011, all data for acetate
was qualified with "B"; samples NDGW02-102011 and NDGW07-102011 did not have detectable
concentrations of acetate and did not require quantification. The source of the acetate was later
determined to be the trisodium phosphate (TSP) preservative.

The field and trip blanks collected on October 18, 2011, were rejected and qualified with "R" for
dissolved gases as the result of carryover from standards analyzed prior to these blanks (see Table A8).
The results for samples collected on this date that were above the QL were qualified because it is not
known if the data quality had been impacted. This affected methane samples from NDGW07-102011,
NDGW08-102011, NDGW09-102011, and NDGW14-102011, and the ethane sample from NDGW08-
102011. No samples for propane or butane were affected since the samples for these analytes were
below the QL.

There were no detectable concentrations of SVOCs in any of the field blank samples (see Table A10).
Therefore, there was no impact on data quality measured by blanks. However, a laboratory method
blank had bis-(2-ethylhexylphthalate). Affected samples (NDGW03-102011, NDGW04-102011,
NDGW05-102011, NDGW06-102011, NDGW07-102011, NDGW08-102011, NDGW09-102011, and
NDGW14-102011) are qualified with a "B".

The ethoxylates, alkylphenols, and acrylamide blanks showed no detectable concentrations except for
nonylphenol ethoxylate and the ethoxylate alcohols C13 (see Table A12). It should be noted that only
four samples were collected for this analysis. The concentration of nonylphenol ethoxylate in the blank
sample was at the QL. Therefore, all samples (NDGW04-102011, NDGW07-102011, NDGW08-102011,
and NDGW09-102011) were qualified with a  "B."  In the case of the ethoxylated alcohols C13 blank, the
concentration was greater than the QL. Samples NDGW04-102011, NDGW07-102011, and NDGW08-
102011 were qualified with a "B."  It is likely that the contamination was from the glass bottles used for
the collection of samples.

A.4.3. October 2012 Sampling
Both equipment blanks had concentrations of dissolved Ni above the QL, and the following samples had
concentrations less than 10 times the concentration in the blanks: NDGW01-102012, NDGW02-102012,
NDGW03-102012, NDGW04-102012, NDGW05-102012, NDGW06-102012, NDGW09-102012, NDGW09-
102012 DUP, and NDGW14-102012. Therefore, these samples were qualified with a "B" qualifier.

Formate was detected in the blanks (see Table A7). All field blanks had concentrations of formate
similar to the concentrations in the samples.  This likely indicates sample container contamination and
the formate  data were rejected and qualified with  "R."
                                            A-8

-------
Appendix A QA/QC Summary, Retrospective Case Study in Killdeer, North Dakota                          May 2015

The ethoxylates, and alkylphenols blanks indicated most of the samples were contaminated (see Table
A12), and all data for ethoxylates and alkylphenols were rejected and were qualified with "R."

A.5.  Duplicate Samples
Field duplicate samples were collected to measure the reproducibility and precision of field sampling
and analytical procedures. The RPD was calculated to compare concentration differences between the
primary (sample 1) and duplicate sample (sample 2) using the following equation:

                                                             100
                                       (sample 1 + sample 2)

RPDs were calculated when the constituents in both the primary sample and duplicate sample were >5
times the method QLs. Constituents were qualified with a "*" if RPDs were >30%.

A.5.1.  All Sampling Events
There were no qualifications required based on RPDs for field duplicates not meeting the 30% criterion.

A.6.   Laboratory QA/QC Results and Data Usability Summary
The QA/QC requirements for laboratory analyses conducted as part of this case study are provided in
the QAPPs.  Table A25 summarizes laboratory QA/QC results regarding sample analysis, i.e., laboratory
duplicate analysis, laboratory blank analysis, matrix spike results, calibration, continuing calibration
checks, and field QC. Impacts on data quality of any issues noted in the QA narratives are also
presented in Table A25. Data qualifiers are listed in Table A26. Many of the specific QA/QC
observations noted in the ADQs are summarized in Table A25.

A majority of the reported data met project requirements. Data that did not meet QA/QC requirements
specified in the QAPP are indicated by the application of data qualifiers in the final data summaries. Data
determined to be unusable were rejected and qualified with an "R." Depending on the data qualifier,
data usability is affected to varying degrees. For example, data qualified with a "B" would not be
appropriate to use when the sample concentration is below the blank concentration. But as the sample
data increase in concentration  and approach lOx the blank concentration, they may be more
appropriate to use. Data with a "J" flag is usable with the understanding that it is an approximate
concentration, but the analyte is positively identified. A "J+" or "J-" qualifier indicates a potential
positive or negative bias, respectively. An "H" qualifier, for exceeding sample holding time, is considered
a negative bias. An "*" indicates that the data are less precise than project requirements. Each case is
evaluated to determine the extent that data are usable or not (see Table A25).

A.7.   Double Laboratory Comparisons
There were no double-laboratory comparisons for the July 2011, October 2011, or October 2012 events.

A.8.   Performance Evaluation Samples
A series of performance evaluation (PE) samples were analyzed by the laboratories conducting critical
analyses to support the HF Retrospective Case Studies. The PE samples were analyzed as part of the
                                             A-9

-------
Appendix A QA/QC Summary, Retrospective Case Study in Killdeer, North Dakota                         May 2015

normal QA/QC standard operating procedures, and in the case of certified labs, as part of the
certification process to maintain certification for that laboratory. The results of the PE tests are
presented in tabular form in the Wise County, Texas, Retrospective Case Study QA/QA Appendix and are
not repeated here. These tables show the results of 1,354 tests; 98.6% of the reported values fell within
the acceptance range. For the ORD/NRMRL Laboratory, a total of 95 tests were performed, with 96.9%
of the reported values falling within the acceptable range. Similarly, for the Shaw Environmental
Laboratory, a total of 835 tests were performed, with 98.7% of the reported values falling within the
acceptable range. The EPA Region 8 Laboratory had a total of 424 tests  performed, with 98.8% of the
reported values falling within the acceptable range. These PE sample results demonstrate the high
quality of the analytical data reported here. Analytes not falling within the acceptable range were
examined, and corrective action was undertaken to ensure data quality in future analysis.

A.9.   QAPP Additions and Deviations
The July 2011 sampling was conducted using the Hydraulic Fracturing Retrospective Case Study, Bakken
Shale, Killdeer and Dunn County, ND, rev. 0 QAPP. The October 2011 sampling was conducted using the
Hydraulic Fracturing Retrospective Case Study, Bakken Shale, Killdeer and Dunn County, ND, rev. 1
QAPP. The October 2012 sampling was conducted using the  Hydraulic Fracturing Retrospective Case
Study, Bakken Shale, Killdeer and Dunn County, ND, rev.  1 QAPP and the Hydraulic Fracturing
Retrospective Case Study, Bakken Shale, Killdeer and Dunn County: Analysis of Samples by the EPA
Region VII Contract Laboratory for the October 2012 Sampling Event, Revision 1, Addendum QAPP.

A.9.1.  July 2011 Sampling Event.
A deviation from the QAPP for this event was the sampling of the supply wells. At the time the QAPP
was written, the  EPA did not know how these wells were set up for sampling, so a general description
was used.  The depot wells required the use of a split-flow system,  with the sample collected from the
side stream that was adjusted to reasonable flow rates for sampling. The well was purged into a tanker
truck before sampling.  The manifold used was decontaminated between sampling locations. A split
sample was collected for field parameters at the same time laboratory samples were collected, since the
volume of water  that could be collected from the aquifer was limited. Filtered samples were first
collected into clean bottles. Once all the samples were collected, the samples were filtered into new
clean bottles to be shipped to the laboratories doing the analysis. This change in  sampling methodology
was incorporated into revision 1 of the QAPP.

An additional deviation from the QAPP was that the ICP-MS metals data were  not reported. These data
were not reported because of concerns with data quality. The reasons stated  were potential
interferences and that interference check standards were not run.  Instead, ICP-OES data were reported
for the ICP-MS metals As, Cd, Cr, Cu, Ni, Pb, Sb, Se, Tl, and U.

A final deviation from the QAPP was that the midday calibration check for the  field data was not done
on July 19, 2011. However, the initial and end-of-day calibration checks were  acceptable, so it is unlikely
that there was an impact on the data.
                                            A-10

-------
Appendix A QA/QC Summary, Retrospective Case Study in Killdeer, North Dakota                          May 2015


A.9.2. October 2011 Sampling Event
The alkylphenols, ethoxylated alcohols, ethoxylated alkylphenols, and acrylamide analyses were added
after the Hydraulic Fracturing Retrospective Case Study, Bakken Shale, Killdeer and Dunn County, ND,
rev. 1 QAPP revision was approved. The ORD/NERL Laboratory did not have the method ready to accept
samples until a few days prior to the sampling. [Note: This was addressed in the next revision of the
QAPP for these analytes.]

A deviation from the QAPP was that all of the ICP-MS metals data were not reported. These data were
not reported because of concerns with data quality.  Instead, ICP-OES data were reported for the ICP-MS
metals As, Cd, Cr, Cu, Ni, Pb, Sb, Se, Tl, and U.

Finally, there was no midday or end-of-day calibration check for the field data on October 19, 2011. The
sampling was completed at midday, but because of an accidental spill of the YSI 5580 Confidence
Solution, no calibration check could be performed for field parameters. The measurements for pH, ORP,
and specific conductance were not qualified but are considered  usable as estimates.

A.9.3. October 2012 Sampling Event
The QAPP  used for this sampling event was Hydraulic Fracturing Retrospective Case Study, Bakken Shale,
Killdeer and Dunn County, ND, rev. 1 QAPP which addressed the sampling and all analyses except for
metals. A deviation from this QAPP was that the metals were analyzed by a different laboratory than the
one used in previous sampling events. The laboratory is a contract laboratory for EPA Region 7. The
contract Statement of Work detailing  the QA/QC requirements was approved prior to the sampling
event. These requirements were subsequently documented in the Addendum to revision 1 of the QAPP.

The field parameter measurements using the YSI meter were problematic because of a faulty sensor
(see Section A10.2). The affected parameters were pH, specific conductivity (SpC), temperature,
dissolved oxygen (DO), and oxygen-reduction potential (ORP). The PI chose to use data for these
parameters that had been collected by Terracon and the state. Because the PI did not know the
calibration and calibration checks frequency used by Terracon and the state, this deviation from the
QAPP required that measurements for these parameters be qualified using the "J" qualifier, indicating
that these were estimated, but the impact was likely minimal.

A.10. Field QA/QC
Field measurements consisted of YSI Model 556 flow-cell readings for temperature, SpC, pH, ORP, and
DO. YSI electrodes were calibrated in  the morning, and performance checks were generally conducted
after initial calibration, at midday, and at the end of each day (see Table A27) using the YSI 5580
Confidence Solution to conduct the performance checks for SpC, ORP, and pH. NIST-traceable buffer
solutions (4.00, 7.00, and 10.01) were used for pH calibration. The YSI ORP standard was used to
calibrate redox potential measurements. The YSI conductivity standard  was used to calibrate specific
conductance measurements. DO sensors were calibrated with air. Prior to field deployment the
electrode assembly and meter were checked to ensure they were in  good working order. In most cases,
performance checks were  within acceptance limits checks (Table A27).
                                            A-ll

-------
Appendix A QA/QC Summary, Retrospective Case Study in Killdeer, North Dakota                          May 2015

Field parameters for this case study consisted of turbidity, alkalinity, total dissolved sulfide species
(IH2S), and ferrous iron. Because field measurements of ferrous iron and dissolved sulfide sometimes
required dilution and all sample preparations and measurements were made in an uncontrolled
environment (i.e., the field), concentration data for these parameters were qualified in all cases as
estimated. Turbidity was measured using a HACH  2100Q Portable Turbimeter and was calibrated using
HACH 2100Q StablCal Calibration Set. The HACH 2100Q StablCal Calibration Set consists of the 20
nephelometric unit (NTU), 100 NTU, and 800 NTU standards, with a 10  NTU calibration verification
standard.  For alkalinity measurements, a  HACH Model AL-DT Digital Titrator was used. The total
dissolved sulfide species and ferrous iron measurements were collected using a HACH DR890 Portable
Colorimeter. The equipment for measuring alkalinity, total dissolved sulfide species, and ferrous iron
measurement accuracy was verified in the lab prior to field deployment using known standards.  In the
field, a blank sample was measured to ensure no cross contamination occurred. In the field, a blank
sample also was measured for turbidity, and a 10  NTU standard was also used to verify the calibration.
These checks were performed after initial calibration, at midday, and at the end of the day.

A.ll. Data  Qualifiers
Data qualifiers are listed in Table A26.  Many factors can affect the quality of data reported for
environmental samples, including factors related to sample collection in the field, transport of samples
to laboratories, and the work conducted by the various analytical laboratories.  The list of qualifiers in
Table A26 is  based on the  Data Qualifier Definitions presented in the EPA Contract Laboratory Program
(CLP) National  Functional Guidelines for Superfund Organic Methods Data Review (US EPA/540/R-01,
2008),  and the EPA CLP National Functional Guidelines for Superfund Inorganic Methods Data Review
(US EPA/540/R/10/011, 2010), with the addition of data qualifiers H and B, which are necessary for
communicating issues that occur during analysis in laboratories not bound by the CLP statement of
work. The R qualifier is used in cases where it is determined that data need to be rejected.  Data
rejection can occur for many reasons, which must be explained in QA/QC narratives. Conditions
regarding the application of qualifiers include:

   •   If the analyte was not detected, then it was reported as  QL).

A.12. Tentatively Identified Compounds  (TICs)
The EPA Region 8 Laboratory reported TICs from SVOC analyses. Several SVOC TICs were identified in
samples and blanks (see Table A28). To be identified as a TIC, a peak had to have an area at least 10% as
large as the area of the nearest internal standard and a match quality greater than 80.  The TIC match
                                             A-12

-------
Appendix A QA/QC Summary, Retrospective Case Study in Killdeer, North Dakota                         May 2015

quality is based on the number and ratio of the major fragmentation ions. A perfect match has a value
of 99. Although the TIC report is essentially a qualitative report, an estimated concentration is
calculated based on a response factor of 1.00 and the area of the nearest internal standard. The search
for TICs includes the whole chromatogram from approximately 3.0 to 41.0 minutes for SVOCs. TICs are
compounds that can be detected, but without the analysis of standards, cannot be confirmed  or reliably
quantified. Oftentimes, TICs are representative of a class of compounds rather than indicating a specific
compound. Only the top TIC is reported for each peak.

A.13. Audits of Data Quality (ADQ)
An ADQ was performed per the EPA/NRMRL Standard Operating Procedure (SOP), Performing Audits of
Data Quality (ADQs), to verify that requirements of the QAPP were properly implemented for the
analysis of critical analytes for samples submitted to laboratories identified in the QAPP associated with
this project.  The ADQs were performed by Neptune and Company, Inc., and reviewed by NRMRL QA
staff.  However, NRMRL QA staff also performed an ADQ on metals for the October 2011 sampling
event. NRMRL QA staff provided the ADQ results to the project's Pis for response and assisted in the
implementation of corrective actions. The ADQ process is an important element of Category I (highest
of four levels in EPA ORD) Quality Assurance Projects, which this study has operated under for all
aspects of groundwater collection and analysis.

Complete  data packages were provided to the auditors for the July 2011, October 2011, and October
2012 sampling events. A complete data package consists of the following:  sample information, method
information, data summary, laboratory reports, raw data (including QC results), and data  qualifiers. The
QAPP was used to identify data quality indicator requirements and goals, and a checklist was prepared
based on the types  of data collected. The data packages were reviewed against the checklist by tracing
a representative set of the data in detail from raw data and instrument readouts through data
transcription or transference through data manipulation (either manually or electronically by
commercial or customized software) through data reduction to summary data, data calculations, and
final reported data. All calibration and QA/QC data were reviewed for all available data packages. Data
summary spreadsheets prepared by the PI were also reviewed to determine whether data had been
accurately transcribed from lab summary reports and appropriately qualified, based on lab and field QC
results.

The critical analytes, as identified in the QAPP, were GROs; DROs; SVOCs; VOCs,  including isopropyl
alcohol, tert-butyl alcohol, and naphthalene; dissolved gases (methane, ethane, propane, and  butane);
trace elements (As, Se, Sr, Ba, and B); major cations (Ca, Mg, Na, K); and major anions (Cl, nitrate +
nitrite, SO4). Also included in the ADQ were the following analytes: all metals analyzed and glycols. The
non-conformances  identified in an ADQ can consist of the following categories: a finding (a deficiency
that has or may have a significant  effect on the quality of the reported results; a corrective action
response is required), or an observation (a deficiency that does not have a significant effect on the
quality of the reported results; a corrective action response is required). The ADQ for the July 2011
sampling event had nine observations, and the October 2011 sampling event had three findings and four
observations. The ADQ for the October 2012 sampling event had no findings and twenty-one
                                            A-13

-------
Appendix A QA/QC Summary, Retrospective Case Study in Killdeer, North Dakota                          May 2015

observations. In most cases, ADQfindings and observations are included in Table A25 along with the
corrective actions taken and data qualifications.

A.14. Laboratory Technical Systems Audits (TSA)
Laboratory Technical Systems Audits (TSAs) were conducted early in the project to allow for
identification and correction of any issues that may affect data quality.  Laboratory TSAs focused on the
critical target analytes.  Laboratory TSAs were conducted on-site at ORD/NRMRL Laboratory and Shaw
Environmental [both laboratories are located at the Robert S. Kerr Research Center, Ada, OK] and at the
EPA Region 8 Laboratory (Golden, CO) which analyzed for sVOCs, DRO and GRO.  Detailed checklists,
based on the procedures and  requirements specified  in the QAPP, related SOPs, and EPA Methods, were
prepared and used during the TSAs.  These audits were conducted with contract support from Neptune
and Co., with oversight by NRMRL QA Staff. The QA Manager tracked implementation and  completion
of any necessary corrective actions.  The TSAs took place in July 2011. The TSAs found good QA
practices in place at each laboratory. There were no findings and six observations across the three
laboratories audited.  All observations were resolved through corrective actions. The observations had
no impact on the sample data quality.

A.15. Field TSAs
For Category 1 QA projects, TSAs are conducted on both field  and  laboratory activities.  Detailed
checklists based on the procedures and requirements specified in the QAPP, SOPs, and EPA Methods
were prepared and used during the TSAs. The field TSA took place during the first sampling event in July
2011 (audit date: July 19, 2011). The results of the audit and the corrective actions are included in Table
A29.

The sample collection, documentation, field measurements (and calibration), and sample handling,
including sample custody and COC operations, were generally performed according to the QAPP.
Municipal wells and depot wells required using a split-flow system, with the sample collected from the
side stream that was adjusted for flow. The well was  purged prior to sampling, with the main flow into a
storage truck. However, the total flow was not a parameter that could be adjusted by the samplers.
The sample stream was  adjusted to a reasonable flow by using the valve on the manifold. This manifold
was cleaned by Terracon between sample locations. In general, Terracon was first to collect their
samples, followed by the collection of EPA samples. The level of drawdown could not be monitored for
the wells that were sampled during this TSA.  Field parameter measurements (pH, ORP, SpC, DO,
temperature, etc.) could not be measured until after the samples for laboratory analysis were collected
due to the nature of the wells. The field parameters were measured using a calibrated YSI 556 MSP and
Hach kits, depending upon the parameter, as described in the QAPP. Filtered samples also  required first
collecting an unfiltered sample, as described in the QAPP. New filters and new pieces of tubing were
used at each sampling location. Field QC samples were also collected. In the field it was not possible to
review every COC against the  QAPP due to the nature of sampling and sample packaging, but these
custody documents are  available at the respective laboratories and copies were provided with the
laboratory data packages.
                                            A-14

Appendix A QA/QC Summary, Retrospective Case Study in Killdeer, North Dakota                         May 2015

Documentation that was reviewed during the ISA for sampling conducted on the monitoring wells the
day prior indicates the QAPP procedures were also followed. Field parameters were measured while
purging, and the purge rate and time were documented. Water levels were also recorded before and
after purging. The monitoring wells were sampled after purging while monitoring for field parameters
(e.g., pH, ORP, SpC, DO, and temperature).

One observation was noted concerning documentation of the YSI Confidence Solution, which was
corrected at the time of the audit; no findings were identified. A summary of the audit and corrective
actions are given in Table A29.

potential interferences and that
interference check standards were not
run.

ICP-OES:
Antimony: The ICP-OES data for Sb
was rejected because of potential
spectral interferences.

Continuing calibration checks were
analyzed at appropriate intervals,
however, some metals (B, Ba, K, Na,
Ag, Si, S, P, and U) were not always
included in the check standards at the
required intervals.
Uranium: High U results (>30 ng/L)
may be due to spectral interference
and/or high quantitation limits using
ICP-OES.

The matrix spikes had low recovery,
ranging from 60-80%. The matrix
spikes were prepared and analyzed
twice with similar results.  A
laboratory control spike was prepared
and analyzed. The laboratory control
spike produced 97.3% recovery. These
results indicate possible matrix
interference.
The likely reason for the matrix spike failure
is that the addition of the matrix spike
caused the sample to become saturated
with respect to a carbonate mineral phase,
such as calcite. This caused the carbonate
to precipitate and therefore caused the low
spike recovery observed. All results were
qualified with a "J-" to indicate a potential
negative bias taken into account for data

Due to sample matrix (e.g., color,
turbidity), sample NDGW09-102012

by a factor of 5. This resulted in most
MS/MSD sample concentrations near
or below the reporting limit, which
cannot be evaluated accurately for
recovery. Only 4-nitroaniline, carbazole
and pentachlorophenol were above
the RL An appropriate MS/MSD for
the SVOCs is not available due to the
need for the dilution performed for
NDGW09-102012.
Because all sample results are non-detect

                         However, the method blank was
                         performed on a day when the distilled

The result is an estimated quantity, but the result may be biased high.
For both detected and non-detected results, there may be a low bias due to low spike recoveries or sample preservation issues.
The analyte is found in a blank sample above the QL and the concentration found in the sample is less than 10 times the concentration found
in the blank.
The sample was prepared or analyzed beyond the specified holding time. Sample results may be biased low.
Relative percent difference of a field or lab duplicate is outside acceptance criteria.
The data are unusable. The sample results are rejected due to serious deficiencies in the ability to analyze the sample

Solution
          QC Narrative
During the audit, it was
recommended to the field team to
be sure to document in the
notebooks the information on the
YSI 5580 Confidence Solution. This
is a recommended step to ensure
traceability.  This is recommended
for any  other reagent information
that is associated with calibration.
           Response
The YSI confidence solution
information (Lot number and
expiration date) was documented in
the field notebook at the time of the
audit.

Data Qualifiers
      <        The analyte concentration is less than the quantitation limit (QL).
               The analyte was analyzed for, but was not detected above the reported QL.
               The analyte was positively identified. The associated numerical value is the approximate concentration of the analyte in the sample (due either to the quality of the data

               generated because certain quality control criteria were not met, or the concentration of the analyte was below the QL).
               The result is an estimated quantity, but the result may be biased high.
               For both detected and non-detected results, the result is estimated but may be biased low.
               The analyte is found in a blank sample above the QL and the concentration found in the sample is less than 10 times the concentration found in the blank.
               The sample was prepared or analyzed beyond the specified holding time. Sample results may be biased low.
               Relative percent difference of a field or lab duplicate is outside acceptance criteria.
               The data are unusable. The sample results are rejected due to serious deficiencies in the ability to analyze the sample and/or meet quality control criteria. Sample results are not
               reported. The analyte may or may not be present in the sample.

               Total Dissolved Solids (TDS) is estimated based on Specific Conductance (SPC): TDS(mg/L) = SPC(mS/cm) * 650.
               Field-determined concentrations of ferrous iron and hydrogen sulfide are screening values.
               Round 1 -1 Not sampled because well went dry.
               Round 1 -1 Not sampled because well went dry.
               Round 1 -11 High uranium results may be due to spectral interference and/or high quantitation limits using ICP-OES. No primary MCL exceedances for U (>30 |ag/L) were
               observed in the October 2011 sampling event. Future sampling events will analyze U using ICP-MS.
               R. Data rejected. Potential spectral (mass or emission) interference for Sb Rounds 1 and 2.
               R. Data rejected. 1,1,2-trichloroethane is subject to alkaline hydrolysis to 1,1-dichloroethene. This reaction could be supported by the sample preservative (trisodium
               phosphate).
               R. Data rejected. Acetate contamination in samples and blanks is due to the sample preservative (trisodium phosphate) for Round 1.
               The method used forglycol analysis is under development. Round 2 - Tetraethylene Gycol data rejected due to low recoveries on spikes and CCVs.
               Round 2 - R. Data rejected. Dissolved gas field and trip blank on 10/18/11 was unusable due to carryover in the gas chromatograph from a standard analyzed prior to this field
               and trip blank.
               Round 3 - R. Data rejected. Formate contamination in Field Blanks.
               Round 3 - R. Data Rejected. Lab analytical issues.

C.I.   Land Use
This section presents descriptions of land uses in Dunn County as a whole, followed by descriptions of
land uses in and around the sampling points of this study. Building on information provided in the
"Study Area Background" section of this report,  information on the use of agricultural land was obtained
from the Cropland Data Layer produced by the National Agricultural Statistics Service (NASS)( U.S.
Department of Agriculture 2012). The NASS data on agricultural land uses are based on satellite imagery
and an extensive agricultural ground checking of the imagery. Figure Cl shows land uses in Dunn County
in 2012. Table Cl shows the percentages of county land devoted to the largest agricultural uses.
Grassland herbaceous and spring wheat growing were the largest agricultural land uses, accounting for
approximately 59% and 12%, respectively, of land in the county.

Land use change data from the U.S. Geological Survey's (USGS) National Land Cover Database for 1992
and 2006 are  not directly comparable (U.S. Geological Survey 2012). However, it was possible to
compare data from 1992 to data from 2001 and to then compare data from 2001 to that from 2006 to
identify land use changes in the 1992 to 2001 and 2001 to 2006 sub-periods (Multi-Resolution Land
Characteristics Consortium 2013). Figure C2 shows land use changes in Dunn County between 1992 and
2001 and between 2001 and 2006, respectively. Table C2 presents data on the changes in land use
during the same two sub-periods. It can be seen from the table that only a very small proportion of the
land in the county changed use during each sub-period.

The population of Dunn County (an indicator of the intensity of land use) has declined throughout the
period (1950-2010), although the rate of decline was much less between 2000 and 2010 (see Figure C3)
(U.S. Census Bureau 2013a, 2013b, 2013c). In 2011, the population density in Dunn County was
approximately 2 persons per square mile, as compared with approximately 10 persons per square mile
for the entire  state  (U.S. Census 2012a). In 2010, no land in Dunn County was taken up by urban areas
(another indicator of the intensity of land use), whereas approximately 0.3 percent of the land in the
entire state was taken up by urban areas (U.S. Census Bureau 2012b).

Employment is another broad indicator of land use in the county. Table C3 identifies the largest
industries, by  employment, in the county. Mining, quarrying, and oil and gas extraction (one of the
production industries) accounted for approximately 19% of employment in Dunn County.

C.2.   Search Area

C.2.1.  Land  Use
Figure C4, which was created using data from the National  Land Cover Database, presents land use maps
for the search area  in 1992 and 2006. The search area encompasses a 3-mile search radius around the
sampling points in the county and was used to focus the analysis of land use patterns and the
environmental records searches. Table C4 presents data on land use in the search area in 1992 and
2006. Although the data for land use in 1992 and 2006 are  not directly comparable because of changes
in data collection methodology, the data from the National Land Cover Database indicate that
grassland/herbaceous and row/cultivated crop land (i.e., land suitable for grazing or used for growing
crops) accounted for the majority of land use in the search area in both years.

C.2.2.  Crop Land
Figure C5 shows land uses, including agricultural uses (crop lands), in the search area in 2012. Table C5
shows the percentages of land devoted to the largest agricultural uses in the search area—grassland,
herbaceous land, and spring wheat and other hay/non-alfalfa cropland.

C.2.3.  Land Use Changes
Figure C6 and Table C6 show land use changes in the search area between 1992 and 2001 and between
2001 and 2006. The table shows that, in general, only a tiny proportion of the land in the search area
changed use during either sub-period.

C.3.    Environmental Records Search
An environmental record search of the area surrounding the Franchuk well was performed by
Environmental Data Resources, Inc. (EDR). EDR provides a service for searching publically available
databases and also provides data from their own proprietary databases. The database search included
reviews of several federal, state, and tribal environmental databases and proprietary EDR environmental
databases for the study area. The search identified the documented use, storage, or release of
hazardous materials or petroleum products (see Attachment 1). Record dates varied based on the
particular database from which the record was obtained. EDR began collecting a majority of the records
in 1991 from the standard databases (State Hazardous Sites Cleanup Act Site Lists [SHWS]; Landfills [LF];
Leaking Underground Storage Tanks [LUST]; Underground Storage Tanks [UST]; Resource Conservation
and Recovery Act [RCRA]; National Priority List [NPL]; Comprehensive Environmental Response,
Compensation and Liability Information System [CERCLIS]; etc.). However,  some databases (e.g., spill
databases) may have records dating back to the 1980s.

The record search was based on a 3-mile-radius search area centered on the location of the Franchuk
well, which experienced a blowout in September 2010.  Because of the large size of the study area, the
search area was chosen based  on  professional judgment.

The identified records included historically contaminated properties; businesses that use, generate,
transport, or dispose of hazardous materials or petroleum products in their operations; active
contaminated sites that are currently under assessment and/or remediation; sites with National
Pollutant Discharge Elimination System (NPDES) and State Pollutant Discharge Elimination System
(SPDES) permits; and active and abandoned mines and landfills. All of the properties listed on the
Environmental Records Search Report were reviewed and screened based  on the EDR record search
findings to determine whether they were potential candidate causes. The criteria used for the screening
included relevant environmental information (including, but not limited to, notices of violations, current
and historical use of the site, materials and wastes at the site, releases and/or spills) and distance from
the sampling points.

Sites that EDR could not automatically map because of poor or  inadequate address information in the
searched databases were not included on the EDR Radius Map. However, EDR determined that,  based
on the limited address information available, it was possible that these sites could be located within the
stated search radius (e.g., zip code listed within searched radius) and were, therefore, listed on the
                                             C-6

-------
Appendix CBackground Data, Retrospective Case Study in Killdeer, North Dakota                          May 2015

Environmental Records Search Report as "orphan" sites. (Orphan sites are those sites with poor
locational information in the databases and so may or may not exist inside the search radius.) All of the
orphan sites were screened to the extent possible based on limited information on those sites available
through additional searches of the databases listed above and information obtained through internet
searches (e.g., EPA website and state websites). Additionally, through a more extensive review of the
available records (including EnviroFacts, business listings, etc.), a location was determined for most
orphan sites and their approximate distance from the sampling points was measured on a map.

C.3.1.  Oil and Gas Well Inventory
Well inventories were prepared for the same search area described above for the EDR reports. All oil
and gas wells identified within the search area were selected for review. Specific focus was placed on
wells within 1 mile of the sampling points. Information was obtained from desktop surveys performed
using searchable state agency databases. The oldest well spud date identified in this study was March
1980.

C.3.2.  State Record Summary
The North Dakota Department of Mineral Resources, Division of Oil and Gas, was contacted to find up-
to-date well records for wells within 1 mile of EPA study sampling locations. The information requested
included inspection and pollution-prevention visits, violations (if noted), and any enforcement that may
have resulted. Not all of the state's records were included in the state's electronic database. Access to
additional paper records can be obtained only by appointment with the particular state regional office.

C.4.    Evaluation of Data for the Killdeer  Site

C.4.1.  Environmental  Records Search Report Summary
A 3-mile-radius search area was established for the EDR database searches to capture the Dunn County
sampling points (see Figure C7). EDR identified 38 records of mapped sites within this search area. An
additional 102 orphan sites were identified during the searches.  An attempt to locate these sites with
information available in the reports  and through internet searches was made to help determine the
potential of these sites to be candidate causes. The evaluation of the sites is summarized in Table C7.
(Some of these records are for the same location, and they are listed together on the table).

The 140 records identified in the EDR reports include facilities with underground storage tanks (USTs)
and aboveground  storage tanks (ASTs),  RCRA-regulated facilities, numerous drilling sites, etc.  Thirty-
seven of the incidents/records/sites have been retained as potential  candidate causes (at 31 locations)
and are identified in the databases described below:

        •   UST/LUST/AST Storage Tanks - Included  sites listed in one of three databases: The
           Aboveground Storage Tank (AST) database, which contains a  list of registered ASTs from the
           North Dakota Department of Health  and  Consolidated Laboratories' AST Data; the
           Underground Storage Tank (UST) database, which contains registered  USTs regulated under
           the Resource Conservation  and Recovery Act (RCRA) (note: the data came from the
           Department of Health's  UST Data); and the Leaking Underground Storage Tank (LUST)
                                              C-7

-------
Appendix C Background Data, Retrospective Case Study in Killdeer, North Dakota                          May 2015

           Incident Reports, which contain an inventory of reported leaking USTs (note: the data are
           from the  Department of Health's LUST List). A total of eight ASTs, and 11 USTs (for a total of
           18 separate locations) were retained (sites with documented cleanup records were not
           retained). Of these 18 sites, 16 are located within 0.5 miles of the sampling points, one is
           less than  2 miles away, and one was retained because location information was insufficient.
           Three of these sites are also listed in the Facility Index System (FINDS) database.
        •   US Hist STAT Auto - This database is a select list of business directories of potential gas
           station/filling station/service station sites that were available to EDR that may not show up
           in current government record searches. A total of three US HIST Auto STAT sites were
           retained as potential gas station/filling station/service station sites and were included as
           potential contributors to groundwater quality impacts because of their proximity to the
           nearest sampling point. One of these sites was also listed in the FINDS database.
        •   Federal RCRA Generators List (RCRA-CESQG) - This database is EPA's information system on
           sites that generate, transport, store, treat, and/or dispose of hazardous waste as defined by
           RCRA. Conditionally exempt small-quantity generators (CESQGs) generate less than 100
           kilograms (kg) of hazardous waste per month. One RCRA-CESQG site was retained because
           of its proximity to the sampling points (less than 0.1 miles north of NDGW16) and recorded
           violations. Hazardous waste generated at this location included barium, chromium, lead,
           methyl ethyl ketone, certain spent non-halogenated solvents (F003 waste), certain spent
           non-halogenated solvents (F005 waste), and ignitable waste. This site was also listed in the
           FINDS database.
        •   RCRA Non-Gen/No Longer Regulated (NLR) Site - This database includes information on
           sites that generate, transport, store, treat, and/or dispose of hazardous waste as defined by
           RCRA. Non-generators do not presently generate hazardous waste and were not retained as
           potential candidate causes, with one exception. This site was retained because of records
           indicating compliance violations. The hazardous waste was not identified on the available
           records.
        •   Facility Index System (FINDS) - This database contains both facility information (North
           Dakota Facility Profile [ND-FP]) and other sources of information from the EPA/National
           Technical Information Service (NTIS). In addition to the five FINDS records for sites that also
           have records in the databases discussed above (UST, US Hist STAT Auto, and RCRA-CESQG),
           two FINDS records were retained  because the sites were near the sampling points and the
           information on facility activities and compliance was insufficient.
        •   Tier 2 - This database records and stores information on Tier 2 locations. Tier 2 records may
           include facilities or sites with recorded chemical storage. Six Tier 2 locations showed
           gasoline,  diesel, oil, motor oil, ethanol, or propane storage and were retained due to their
           proximity to the sampling points (within 0.5 miles).

C.4.2.  Oil and Gas Well  Inventory Summary
The EPA Study sampling locations were compared with the inventory of wells identified in database files
from the North Dakota Department of Mineral Resources, Division of Oil and Gas (see Table C8).
                                              C-8

-------
Appendix CBackground Data, Retrospective Case Study in Killdeer, North Dakota                         May 2015

Thirty-five oil and gas wells are located within 3 miles of the Franchuk well. Of these wells, seven are
within 1 mile of the EPA Study sampling locations (see Table C9). The presence of these oil and gas wells
increases the probability of one or more of these features being a potential candidate cause for
groundwater contamination.

C.4.3. State Record Summary
Notice of Violations. Notices of violations (NOVs) were researched for all oil and gas wells within a 1-
mile radius of the EPA study site. Although no NOVs were identified by the North Dakota Department of
Mineral Resources (NDDMR),  Division of Oil and Gas, NDDMR did provide incident notes regarding the
Franchuk 44-20SWH well. In addition, after subsequent inquiries, NDDMR also provided the following
additional information and stated that there were no NOVs on record for the Franchuk well because the
fine had been paid:

    •  The Industrial Commission, on March 30, 2011, filed a complaint against Encore Operating, LP.
       (Encore) and Denbury Resources,  Inc. (Denbury) for violating North Dakota Administrative
       Code(NDAC) Section 43-02-03-28  by failing to properly control subsurface pressure during the
       completion operation, NDAC Section 43-02-03-49 by allowing oil to flow over and pool on the
       surface of the land, NDAC Section 43-02-03-53 by allowing brine to flow over and pool on the
       surface of the land, and NDAC Section 43-02-03-11 by failing to properly notify the Commission
       when Denbury acquired Encore and  the Franchuk 44-20SWH well  in Dunn County, North
       Dakota.
    •  In the complaint, the Commission requested Encore and Denbury to pay a $237,500 fine and
       $5,236 in costs and expenses incurred by the Commission.
    •  In lieu of a formal hearing on the complaint, Denbury paid the $237,500 fine and $5,236 in costs
       and expenses incurred by the Commission.

   Therefore, this case was dismissed on December 7, 2011.

Databases:
AIRS: Permitted Airs Facility Listing.
AST: Aboveground Storage Tank Listing. The data come from the Department of Health & Consolidated Laboratories' AST Data (Facility & Owner Address of the Tanks Currently Recorded in North Dakota).
FINDS: Facility Index System of the U.S. EPA/NTIS database that contains both facility information and "pointers" to other sources of information that contain more detail. It includes: RCRIS; Permit Compliance System (PCS);
Aerometric Information Retrieval System (AIRS); FATES (FIFRA [Federal Insecticide Fungicide Rodenticide Act] and TSCA Enforcement System, FTTS [FIFRA/TSCA Tracking System]; CERCLIS; DOCKET (Enforcement Docket
used to manage and track information on civil judicial enforcement cases for all environmental statutes); Federal Underground Injection Control (FURS); Federal Reporting Data System (FRDS); Surface Impoundments (SIA); TSCA
Chemicals in Commerce Information System (CICS); PADS; RCRA-J (medical waste transporters/disposers); TRIS; and TSCA.
FTTS: FIFRA (Federal Insecticide, Fungicide, & Rodenticide Act)/TSCA (Toxic Substances Control Act) Tracking System. FTTS tracks administrative cases and pesticide enforcement actions and compliance activities related to
FIFRA, TSCA and EPCRA (Emergency Planning and Community Right-to-Know Act).
HIST FTTS: FIFRA/TSCA Tracking System Administrative Case Listing: A complete administrative case listing from the FTTS for all 10 EPA regions. The information was obtained from the National Compliance Database (NCDB)
that NCDB supports the implementation of FIFRA and TSCA. Some EPA regions are now closing out records. Because of that, and the fact that some EPA regions are not providing EPA Headquarters with updated records, it was
decided to create a HIST FTTS database. It included records that may not be included in the newer FTTS database updates. This database is no  longer updated.
HIST FTTS INSP: FIFRA/TSCA Tracking System Inspection & Enforcement Case Listing: A complete inspection and enforcement case listing from the FIFRA/TSCA Tracking System (FTTS) for all ten EPA regions. The information
was obtained from the NCDB.
ICIS: Integrated Compliance Information System. ICIS provides a database that, when complete, will contain integrated Enforcement and Compliance information across most of EPA's programs.
LUST: The Leaking Underground Storage Tank Incident Reports contains an inventory  of reported leaking underground storage tank incidents.  The data come from the Department of Health's LUST List.

NPDES: National Pollutant Discharge Elimination System Permit Listing
RCRAInfo: RCRAInfo is EPA's comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments of 1984. The
database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the RCRA.
RCRA-CESQG: Federal RCRA Conditionally Exempt Small Quantity Generator List.
RCRA NonGen/NLR: RCRAInfo listings of RCRA Non-Generators /No longer regulated. Non-Generators do not presently generate hazardous waste.
RMP: List of facilities with Risk Management Programs. The RMP Rule, which was built upon existing industry codes and standards, requires companies of all sizes that use certain flammable and toxic substances to develop a Risk
Management Program.
TIER 2: Listing of Tier 2 information.
US Hist Auto Stat: EDR's database of listings of potential gas station/filling station/service station sites that were available to EDR researchers. EDR's review was limited to those categories of sources that might, in
EDR's opinion, include gas station/filling station/service station establishments. The categories reviewed included, but were not limited to gas, gas station, gasoline station, filling station, auto, automobile repair, auto
service station, service station, etc. This database falls within a category of information EDR classifies as "High Risk Historical Records", or HRHR. EDR's HRHR effort presents unique and sometimes proprietary data
about past sites and operations that typically create environmental concerns, but may not show up in current government records searches.
UST: The Underground Storage Tank database contains registered USTs. USTs are regulated under  Subtitle I of the Resource Conservation and Recovery Act (RCRA). The data come from the
Department of Health's UST Data (Facility & Owner Address of the Tanks Currently Recorded in North Dakota).
Waste Code D001 - Ignitable hazardous wastes are those wastes which have a flashpoint of less than  140 degrees Fahrenheit as determined by a Pensky-Martens closed cup flash point tester.
Waste Code D002 - A waste which has a pH of less than 2 or greater than 12.5 is considered to be a corrosive hazardous waste.
Waste Code D005 - Barium
Waste Code D007 - Chromium.
Waste Code D008 - Lead.
Waste Code D009 - Mercury.
Waste Code D018 - Benzene.
Waste Code D035 - Methyl ethyl ketone.

 Federal CERCLIS NFRAP site List

 CERCLIS-NFRAP: CERCLIS  No Further Remedial Action Planned
      Archived sites are sites that have been  removed and archived from the inventory of CERCLIS sites. Archived status
      indicates that, to the best of EPA's knowledge, assessment at a site has been completed and that EPA has determined
      no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates
      this decision was not appropriate or other considerations require a recommendation for listing at a later time.
      This decision does not necessarily mean that there is no hazard associated  with a given site; it only means that,
      based upon available information, the location is not judged to be a potential NPL site.

 US BROWNFIELDS: A Listing of Brownfields Sites
      Brownfields are real property, the expansion, redevelopment, or reuse of which may be complicated by the presence
      or potential presence of a hazardous substance, pollutant, or contaminant. Cleaning up and reinvesting in these
      properties takes development pressures off of undeveloped, open land, and both improves and protects the environment.
      Assessment, Cleanup and Redevelopment Exchange System (ACRES) stores information reported by EPA Brownfields
      grant recipients on brownfields properties assessed or cleaned up with grant funding as well as information on
      Targeted Brownfields Assessments performed by EPA Regions. A listing of ACRES Brownfield sites is obtained from
      Cleanups in My Community. Cleanups in My Community provides information on Brownfields properties for which information
      is reported back to EPA, as well as areas served by Brownfields grant programs.

GOVERNMENT RECORDS  SEARCHED / DATA CURRENCY TRACKING
      When Congress passed the Clean Air Act Amendments of 1990, it required EPA to publish regulations and guidance
      for chemical accident prevention at facilities using extremely hazardous substances. The Risk Management Program
      Rule (RMP Rule) was written to implement Section 112(r) of these amendments. The rule, which built upon existing
      industry codes and standards, requires companies of all sizes that use certain flammable and toxic substances
      to develop a Risk Management Program, which includes a(n): Hazard assessment that details the potential effects
      of an accidental  release, an accident history of the last five years, and an evaluation of worst-case and alternative
      accidental releases; Prevention program that includes safety  precautions and maintenance, monitoring, and employee
      training measures; and  Emergency response program that spells out emergency health care, employee training measures
      and procedures  for informing the public and response agencies (e.g the fire department) should an accident occur.

 EPA WATCH LIST:  EPA WATCH LIST
      EPA maintains a  "Watch List" to facilitate dialogue between EPA, state  and local environmental agencies on enforcement
      matters relating to facilities with alleged violations identified as either significant or high priority.  Being
      on the Watch List does not mean that the facility has actually violated the law only that an investigation by
      EPA or a state or local environmental agency has led those organizations to allege that an unproven violation
      has in  fact occurred. Being on the Watch  List does not represent a higher level of concern regarding the alleged
      violations that were detected, but instead indicates cases requiring additional dialogue between EPA, state and
      local agencies - primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

 2020 COR ACTION: 2020 Corrective Action Program List
      The EPA has set ambitious goals for the RCRA Corrective Action program by creating the 2020 Corrective Action
      Universe. This RCRA cleanup baseline includes facilities expected to need corrective action. The 2020 universe
      contains a wide variety of sites. Some properties are heavily contaminated while others were contaminated but
      have since been cleaned up. Still others have not been fully investigated yet, and may require little or no remediation.
      Inclusion in the 2020 Universe does not necessarily imply failure on the part of a facility to meet its RCRA obligations.

 EDR HIGH RISK HISTORICAL RECORDS

 EDR Exclusive Records

 EDR MGP: EDR Proprietary Manufactured Gas Plants
      The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)
      compiled by  EDR's researchers. Manufactured gas sites were used in the United States from the 1800's to 1950's
      to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture
      of coal,  oil, and waterthat also produced a significant amount of waste. Many of the byproducts of the gas production,
      such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds
      are potentially hazardous to human health and the environment. The byproduct from this process was frequently
      disposed of directly  at the plant site and can remain or spread slowly, serving as a continuous source of soil
      and groundwater contamination.
                                                                                                TC3602489.16S   Page GR-20

 Sensitive Receptors:   There are individuals deemed sensitive receptors due to their fragile immune systems and special sensitivity
 to environmental discharges.  These sensitive receptors typically include the elderly, the sick, and children. While the location of all
 sensitive receptors cannot be determined, EDR indicates those buildings and facilities - schools, daycares, hospitals, medical centers,
 and nursing homes - where individuals who are sensitive receptors are likely to be located.
