Concentrated Animal Feeding Operations (CAFOs) are increasing in size and generating consider-
ably more waste requiring disposal over an increasingly limited area. As livestock production has
become more spatially concentrated, the amount of available manure nutrients often exceeds the
assimilative capacity of the land on the farms, resulting in both ground and surface water contami-
nation. Ground water has long been recognized as an essential resource for drinking water and
irrigation water, but it is also an important conduit for transfer of contaminants to surface waters.
Potential ground water contaminants arising from CAFOs include dissolved solids, nutrients, metals
and metalloids, pathogens, antibiotics, and natural and synthetic hormones. Ground water protec-
tion will only be as adequate as allowable under site-specific Nutrient Management Plans (NMPs),
which serve as one of the few risk management tools for ground water protection. Few data exist
which show whether proper NMPs are being developed or rigorously followed. Additional research
on land application of CAFO wastewater on agricultural lands is also needed to assess whether risk
management strategies used to prevent ground water contamination by nutrients (primarily nitrate)
are equally protective with respect to other contaminants.
To address this issue, field studies were conducted to ascertain whether nitrate-impacted ground
waters at commercial CAFO facilities were also contaminated with other stressors present in those
CAFO wastes. Seven case studies are presented, including a swine finisher operation, a poultry
layer operation (since closed), a swine nursery operation, a dairy operation, a combined swine
operation (since closed), a beef feedlot operation, and a swine farrowing sow operation. With
the exception of the swine farrowing sow operation, which essentially served as a relatively non-
impacted site, each of these case study sites exhibited ground water contamination by nitrate and/
or ammonium. For most sites, this resulted directly from the operation, either through leaking
infrastructure piping, leaking lagoons, or land application of CAFO waste, as supported through the
monitoring of stable nitrogen isotopes. The primary focus was on nutrients (nitrate, ammonium,
orthophosphate) and natural estrogen hormones (estrone, 17a-estradiol, 17(3-estradiol, andestriol),
but other stressors that were analyzed at each site and are discussed included microbial indicators
(total coliforms, fecal coliforms, fecal enterococci), metals and metalloids (arsenic, copper, nickel,
selenium, and zinc), and antibiotics (selected macrolides, quinolines, sulfonamides, tetracyclines,
and other antibiotics). These stressors were measured in CAFO lagoons as well as in ground waters
from monitoring wells and other site wells. Extensive sampling and analyses were conducted
during one to three sampling events per site, although two of these sites were monitored annually
for approximately ten years, albeit for not all of the parameters listed above.
With the exception of the closed swine combined operation which had impacted ground water
directly through a leaking lagoon, ground water contamination for most of these sites was limited to
nitrate, and occasionally ammonium, only. This wras somewrhat surprising, since several contami-
nated ground water samples at each of the sites showed a moderate to strong animal waste signature
based on stable nitrogen isotopes, and nitrate concentrations often exceeded 50 to 100 mg/L N03- N
in these samples. Fecal coliforms were only sporadically detected at high concentrations in a few
wells at some of the sites, and in most cases there were greater numbers of fecal enterococci com-
pared to fecal coliforms. There was little correlation between microbial indicator counts and nitrate
concentrations. Similarly, concentrations of metals and metalloids were generally low in these
ground water samples and showed little correlation with nitrate concentrations. Sulfonamides,
-------
tetracyclines, and other antibiotics were detected at high concentrations (mg/L range) in swine
lagoons and, to a lesser extent, in dairy lagoons, but only lincomycin, sulfamethazine, and
sulfamethoxazole were detected in any of the ground water samples. Even in these cases, con-
centrations were close to the method reporting limits (low to mid ng/L range). Of these three
antibiotics, lincomycin was detected at the greatest frequency in ground water samples, being
present in one or more ground water samples at three of the six sites with CAFO-impacted ground
waters. Again, there was little correlation of the presence of antibiotics with either nitrate concen-
tration or with animal waste signature as indicated by stable nitrogen isotopes. With the exception
of the closed combined swine operation, estrogen hormones (primarily estrone) were only sporadi-
cally detected in ground water samples, and again concentrations were very low (0.5-2.7 ng/L).
The closed combined swine operation was the only site with significant ground water contami-
nants other than nitrate, and this was most likely due to direct and extensive leakage of the original
lagoon swine waste into the shallow aquifer over several years. Unlike the other operations,
ammonium concentrations were quite high in several of the ground water samples, with four wells
generally ranging from 50-200 mg/L NH4-N during annual monitoring from 2003 to 2011. These
wells also had elevated levels of arsenic and estrogen hormones. Arsenic concentrations, as more
accurately measured by ICP-MS in 2009, ranged from 84-126 (ig/L in these ground water samples
compared to much lower levels in most of the other wells. Estrogen hormones were also con-
sistently detected in these ground water samples over this time period, with the levels of estrone
being the highest (11,200 ng/L maximum), followed by estriol (824 ng/L maximum) and then
17p-estradiol (41 ng/L maximum). These estrogen concentrations have generally been decreas-
ing over time, and the maximum concentrations in 2011 were 388 ng/L for estrone, < 0.3 ng/L for
estriol, and < 2.1 ng/L for 17(3-estradiol.
Collectively, these data show that ground water contamination by nitrate or ammonium can occur
at very different types of CAFOs, whether through leaking lagoons, leaking pipes or infrastructure,
land application of wastes in excess of agronomic needs, or other factors. However, we found
little evidence of significant ground water contamination by other stressors at these sites, except
in cases where CAFO wastes leaked directly from the lagoons into associated aquifers. Even in
those cases, where ground water nitrate concentrations greatly exceeded the MCL and moderate to
high levels of ammonium could also be detected, the other stressor concentrations were generally
quite low. This suggests, but does not necessarily imply, that if CAFOs were properly managed
so as to preclude ground water contamination by nitrate in excess of the MCL, then other stressors
associated with CAFO wastes (metals, metalloids, antibiotics, and estrogen hormones) might also
be attenuated to acceptable risk levels. Additional field studies are needed to test this hypothesis,
preferably with more frequent sampling events to account for seasonal variations and long-term
effects. It is important to note that this study did not evaluate true pathogens, other hormones
(e.g., trenbolone), or other antibiotics (e.g., monensin), and additional research is also needed to
ascertain whether these stressors would exhibit similar potential for contaminating ground water
through leaking lagoons or land application of CAFO wastes. In addition, it should also be noted
that this study does not address long-term effects from the buildup of salts and other compounds
on ground water quality or soil productivity. Finally, these results should not obscure the fact that
contamination of ground water by nitrate or ammonium is in itself a significant environmental
problem and can lead to legacy impacts on receiving surface waters with direct hydrologic con-
nection to contaminated ground waters. Much more work is needed to address the efficacy of
current CAFO nutrient management strategies (i.e., BMPs) for ground wrater protection from con-
tamination by nutrients as well as other stressors, and to ascertain whether additional guidance or
regulatory controls are needed.

1.0 Introduction
In the United States, there are approximately one million farms with livestock, of which
about 212,000 confine animals and are defined as animal feeding operations (AFOs)
under current regulations (USEPA, 2012a). A facility is an AFO if animals are stabled or
confined and fed or maintained for 45 days or more within any 12-month period, and
crops, vegetation, forage growth, or post-harvest residues are not sustained in the normal
growing season over any portion of the lot or facility. Approximately 20,000 of these are
large enough to be classified as concentrated animal feeding operations (CAFOs) which,
under previous definitions, were generally considered to be operations with more than
1,000 animal units (USEPA, 2012a). AFOs generate approximately 500 million tons of
manure each year which must be properly treated and disposed or utilized to prevent
contamination of soil, air, and water (USEPA, 2003). Animal manure is a valuable
source of nutrients and has been used as fertilizer to enhance production of agricultural
crops and forage. However, there have been substantial changes in the U.S. animal
production industry over the past several decades. Although the total number of
operations has decreased, overall production has increased. As a result, CAFOs are
increasing in size and generating considerably more waste requiring disposal over an
increasingly limited area. As livestock production has become more spatially
concentrated, the amount of available manure nutrients often exceeds the assimilative
capacity of the land on the farms, especially in high production areas, and studies have
shown that this problem is becoming much more widespread (Kellogg et al., 2000). The
problem is not just limited to nutrients, and the industrialization of livestock production
in the U.S. over the past three decades has not been accompanied by either improvements
in waste treatment technologies or the corresponding changes in environmental
regulations necessary to protect public health (Thorne, 2007).
In addition, CAFO demographics are changing, and an increasing number of these
operations are expanding to the central and western regions of the U.S., where land is
often less expensive and located away from major population centers. This is especially
1
-------
true for dairy operations (USDA, 2002), but it has occurred for swine operations as well.
For example, in 1997 Oklahoma became the 8th leading swine-producing state in the
United States, up from 26th in 1992, with the production of swine increasing from
200,000 to 2,950,000 in a relatively short span of six years (Luckey and Becker, 1999).
There are many reasons for these types of demographic shifts, but one of the most
important may be the semiarid nature of the central and western regions, which results in
limited rainfall and relative lack of number of rivers and larger surface water bodies
compared to the eastern U.S. This means that CAFOs that rely on open lagoons for
storage of liquid manure, as is often the case with swine operations, can have smaller
lagoons in place because of enhanced evaporation rates and less rainfall. Also, the
potential for surface water contamination by agricultural runoff is lessened in areas with
more limited rainfall events and greater distances to rivers and streams, which makes it
easier for these operations to dispose more waste and still achieve regulatory compliance.
Finally, in some of these areas unaccustomed to experiencing growth in the animal
industry, adequate state or local regulations may not yet be in place to sufficiently protect
the environment, and the attraction of economic growth in poorer communities may
outweigh the environmental concerns on a local level (Wing and Wolf, 2000; Donham et
al., 2007).
1.1 Ground Water Vulnerability to CAFO Impacts
Ground water has long been recognized as an essential national resource, accounting for
40% and 36% of the nation's drinking water and irrigation water, respectively (Alley et
al., 1999). However, it is seldom recognized that ground water is also an important
conduit for transfer of contaminants to surface waters, and nationally, approximately 40%
of the average annual streamflow in the U.S. is from ground water (Alley et al., 1999). In
addition, much of the agricultural land in the Midwest and East Coast is underlain by tile
drains which can also eventually discharge into wetlands, streams, rivers, and lakes
(Jaynes and James, 2012). CAFO impacts on ground water quality can therefore be
considered as an emerging risk issue for surface water quality. Unlike surface waters,
ground waters are not exposed to light, are often low in dissolved oxygen, and generally
-------
contain less organic carbon, all of which can lead to greater persistence of organic and
inorganic contaminants. A case in point is the High Plains aquifer, which underlies parts
of eight states in the Midwest and is the most intensively used aquifer in the U.S.,
producing almost two times more water than any other U.S. aquifer (Luckey and Becker,
1999). Although this aquifer accounts for about 20% of all ground water used in the U.S.,
the natural rate of nitrate attenuation is slow in most parts and it is estimated that
hundreds to thousands of years would be required to lower nitrate concentrations by just
1 mg/L NO3-N (Gurdak et al., 2009).
Recent events regarding waste releases and algal blooms in the eastern U.S. have
prompted a closer evaluation of the environmental impact of CAFOs on surface waters.
Nationally, agriculture accounts for 59% of all sources of impairment for rivers, and
CAFOs directly contribute 16% to total agricultural impact through surface water runoff
(USEPA, 200la). However, the impact of agriculture to ground water is relatively
unknown, and there are no estimates for impairment due specifically to CAFOs.
Contaminants can enter ground water from a variety of CAFO sources, including leaking
lagoons, breaches in piping or barn infrastructure, and land application of liquid and solid
wastes. There are guidelines for design and construction of barns, infrastructure piping,
and lagoons that in theory would preclude leakage to ground water, but in practice these
events do occur (Ham and DeSutter, 2000; Krapac et al., 2002). In fact, even when
properly constructed, slow leakage from lagoons over time can release large amounts of
contaminants such as ammonium (Ham and DeSutter, 1999). In the central and western
regions of the U.S., sparse rainfall, relative lack of surface water streams, and the
availability of readily-permeable soils promote land application of CAFO waste,
exacerbating the potential for ground water contamination. Because depths to ground
water can exceed hundreds of feet in these areas, ground water contamination may not be
realized for years. Land application practices in theory are designed to allow nitrogen
uptake by the crops and vegetation, and under appropriate conditions can be used in a
sustainable manner (Bastian, 2005; O'Connor et al., 2005; Pierzynski and Gehl, 2005;
Van Es et al., 2006; Hatfield, 2009). But there have been reports of ground water
contamination by nitrate even when proper management strategies are being followed
-------
(Karr et al., 2001; Decau et al., 2004; Showers et al., 2008), including a recent study in
Arkansas, where high levels of nitrate were transported through the soil profile, despite
adherence to an approved NMP which allowed dairy cows to loaf in the land application
area (Moore and Brauer, 2009).
1.2 Regulatory Mechanisms and Needs
The Clean Water Act prohibits the discharge of pollutants from a point source to waters
of the United States except as authorized by a National Pollutant Discharge Elimination
System (NPDES) permit, and also requires EPA to establish national technology-based
effluent limitations guidelines and standards for different categories of sources (USEPA,
200la). In 1974 and 1976, EPA promulgated regulations that established these
guidelines and permitting regulations for CAFOs. Since that time, these rules had not
kept pace with the growth of the animal industry and had become inadequate for
environmental protection. In 1998, President Clinton released the Clean Water Action
Plan (CWAP), which described 111 specific actions to expand and strengthen existing
efforts to protect water quality. As part of this effort, the CWAP called for the
development of a USDA-EPA unified national strategy to minimize the water quality and
public health impacts of CAFOs, and this strategy was published in 1999. In 2003, EPA
addressed one of the strategic issues, implementing and improving the existing regulatory
program, by finalizing revisions to NPDES permit regulation and effluent limitations
guidelines and standards for CAFOs, 40 CFR Parts 122 and 412 (USEPA, 2003). This
rule, also known as the CAFO Rule, replaced rules and regulations that had been
governing CAFO operations for the previous 25 years. Under this rule, all Large CAFOs
that had a potential to discharge or that actually discharged into waters of the U.S. were
required to apply for an NPDES permit, develop and follow a site-specific Nutrient
Management Plan (NMP), and submit an annual report. In addition, the rule eliminated
the exemption that excuses CAFOs from applying for permits if they only discharged
during large storms, eliminated the exemption for poultry operations with dry manure
handling systems, and extended permitting requirements to immature swine and
immature dairy cows. Since 2003, there have been challenges and revisions to the 2003
-------
CAFO Rule, primarily concerning the provision of the potential to discharge and the
disclosure and use of site-specific NMPs (USEPA, 2012b). Currently, for Large CAFOs,
the 2012 Final CAFO Rule requires NPDES permits only for those operations that
actually discharge into waters of the U.S., and requires that the terms of the NMPs must
be publicly disclosed and included in the permit. Regarding land application, facilities
are required to establish protocols to land apply manure, litter or process wastewater in
accordance with site-specific nutrient management practices that ensure appropriate
agricultural utilization of the nutrients in the manure, litter or process wastewater
(USEPA, 2012c). Specifically, with respect to protocols for land application, the terms
must include the fields, field-specific rates of application, and timing limitations for land
applying manure as terms of the permit. Lastly, once the terms of the NMP becomes
terms of the permit, the NMP and the permit terms are to be made available for public
review and comment. Regarding unpermitted facilities, there is still some regulatory
incentive to follow sound land application practices, in that for a precipitation-related
discharge to qualify as an exemption under agricultural stormwater and not be subject to
NPDES permit requirements, the wastewater must be applied in accordance with site-
specific practices that ensure appropriate utilization of nutrients. Efforts are currently
underway to address some of these nutrient management issues through a reworking of
the CAFO Rule (USEPA, 2010a).
Despite these advances, it is still not clear whether the 2012 Final CAFO Rule will
provide sufficient protection of ground water resources, since the emphasis is clearly on
NPDES discharges, and therefore ground water protection will only be as adequate as
allowable under site-specific NMPs. For example, CAFO operators are still permitted to
apply manure to frozen, snow-covered, or saturated ground. In developing the 2003
CAFO Rule, EPA had originally proposed that all CAFOs be required to prevent
discharges to the ground water beneath production areas, but received numerous
comments opposing ground water protection and monitoring requirements. Arguments
were based on the premise that EPA lacked the authority to directly regulate ground
water contamination in this rule and that the cost to comply with the proposed
requirements would threaten the viability of these operations. Under the Clean Water Act,
-------
EPA does have authority to control discharges to surface water via ground water when it
has been established that ground water has a direct hydrologic connection with surface
water. However, in the 2003 CAFO Rule, EPA rejected establishing national
requirements on discharges to surface waters via ground waters with a direct hydrologic
connection based on the scientific uncertainties and site-specific considerations required
to regulate discharges. Direct ground water protection instead has been afforded through
the Safe Drinking Water Act (SDWA) that was passed in 1974 to protect public health by
regulating the nation's public drinking water supply (USEPA, 2004). The emphasis of
the SDWA was on public water supplies, and it does not regulate private wells that serve
fewer than 25 individuals. Originally, the SDWA focused primarily on treatment as the
means of providing safe drinking water at the tap, but the 1996 amendments greatly
enhanced the existing law by recognizing, among other things, source water protection.
However, neither the SDWA nor the 2012 Final CAFO Rule requires monitoring of
CAFOs for possible ground water contamination, and this is often left to the discretion of
the individual states. In Oklahoma, for example, CAFOs are required to install
monitoring wells upgradient and downgradient of waste storage facilities, but not at land
application sites (ODAFF, 2011). In 2000, a review of all data from swine CAFOs in
Oklahoma showed that 51% of all wells at swine CAFOs did not yield water; of those
that did, 24% had nitrate levels exceeding 10 mg/L nitrate-nitrogen (NOs-N), the
maximum contaminant level (MCL) established under the National Primary Drinking
Water Regulations of the SDWA (Becker et al., 2002). It is expected that this percentage
would have increased substantially if monitoring wells were installed on or adjacent to
land application areas of these facilities. Once ground water becomes contaminated,
States and EPA may elect to pursue specific enforcement actions that may lead the way
to prevent further contamination. For example, the SDWA has been used to require
CAFO operators to provide drinking water to families whose wells have been
contaminated by nitrate from CAFOs (USEPA, 200Ib) and actions have also been taken
using the Resource Conservation and Recovery Act (RCRA) to classify loss of effluent
from swine lagoons and associated infrastructure as a discarded material and thus a solid
waste (USEPA, 200Ic). While effective, these actions require significant investments in
-------
time and resources for enforcement personnel, and prevention, rather than remediation
and mitigation, is a much more preferable route towards sustainable agriculture.
Overall, this indicates that State regulations, as well as Federal regulations, for CAFOs
may not be sufficiently protective of ground water, and there is a clear need to better
assess the efficacy of existing Best Management Practices (BMPs) which form the basis
of NMPs (Burkholder et al., 2007). It also remains to be seen whether a majority of
CAFOs will develop adequate NMPs and whether these will be rigorously followed.
Clearly, additional case studies are needed to provide both an assessment of existing
BMPs as well as to provide the data required to support future rulemaking efforts.
1.3 CAFO Stressors Potentially Impacting Ground Water Quality
Potential ground water contaminants arising from CAFOs include dissolved solids,
nutrients, pathogens, metals and metalloids, pharmaceutical chemicals, and natural and
synthetic hormones. These Stressors can enter ground water from a variety of CAFO
sources, including disposal of dead animals, leaking lagoons, breaches in piping or barn
infrastructure, and land application of liquid and solid wastes. Much of the ground water
quality information centers on nutrients, and in fact nitrate may prove to be the primary
ecological stressor. Reactive nitrogen (nitrate and ammonium) is considered to be a
potent ecological stressor on a global scale, and recommendations for reducing it in the
U.S. include increased controls of oxides of nitrogen, improved reactive nitrogen uptake
by agricultural crops, large-scale creation and restoration of wetlands for nitrogen
removal in agricultural landscapes, decreased loss of reactive nitrogen from agricultural
lands and AFOs, and decreased discharge of reactive nitrogen from point sources and
developed (urban) lands (USEPA, 201 Ob). CAFO lagoons contain high concentrations of
ammonium nitrogen and organic nitrogen, both of which constitute important sources of
nitrogen for crops when these wastes are land applied (Bradford et al., 2008).
Ammonium nitrogen is available for direct uptake by plants, and organic nitrogen is
readily broken down under a variety of conditions to produce additional ammonium
nitrogen. However, although ammonium is strongly sorbed to the soil, it is also readily
-------
converted to nitrate under aerobic conditions through nitrification (Alexander, 1977).
Because nitrate is readily mobile, it can be easily leached from soil and can contaminate
ground water, and so it is essential that CAFO wastes be applied only at agronomic rates
(Bradford et al, 2008). Although ground water bacteria can readily convert nitrate to
nitrogen gas through denitrification, the process generally requires an easily assimilated
organic carbon source and is not favored under aerobic conditions (Alexander, 1977).
Nitrate is detected much more often in ground water than ammonium or phosphate
(Nolan and Stoner, 2000), and nitrate-contaminated ground water can therefore serve as
an important source for subsequent eutrophication of surface waters. Regarding nutrients,
phosphate is also a major stressor and can lead to eutrophi cation of surface waters, but
phosphate impacts to ground water from CAFO operations are expected to be low except
for cases where over-application exceeds the assimilative capacity of the soil and crops
(Bradford et al, 2008). Regardless, this has been documented in ground water impacted
by agricultural operations, and transport of phosphate in ground water to surface water
has been demonstrated as well (Domagalski and Johnson, 2011).
CAFOs can also provide the mechanisms for direct introduction of pathogens into
subsurface systems through land application of liquid and solid wastes, and there have
been numerous studies on the microbial ecology of pathogens in livestock wastes and
their subsequent fate and transport (Guan and Holley, 2003; Hill, 2003; Gerba and Smith,
2005; Hutchinson et al., 2005). The main focus has been on the protozoa
Cryptosporidiumparvum andGiardia spp. (Atwill et al., 2006; Bradford et al., 2006;
Jellison et al., 2007), the bacteria Escherichia coli O157:H7, Salmonella enterica, and
Campylobacter jejuni (Cornick and Helgerson, 2004; Bae et al., 2005; You et al., 2006;
Holley et al., 2008; Kunze et al., 2008; Sharma et al., 2008), and the enteric viruses
(Meng et al; 1997; Fong and Lipp, 2005; Kasorndorkbua et al., 2005; Hundesa et al.,
2006). Because of their smaller size, viruses can more easily be transported through the
soil and vadose zone during land application than bacteria and protozoans, and can also
remain infectious. Over half of the waterborne disease outbreaks in the U.S. between
1971 and 1994 were associated with ground water sources, and at least 10% of these were
caused by viruses (Abbaszadegan et al., 2003). Because of the complexities and expense
-------
involved with analyzing water samples for all of these pathogens, microbial indicators
(total coliforms, fecal coliforms, and fecal enterococci) are still widely used to provide an
indication of microbial water quality, despite inherent limitations in underestimating
levels of viruses and other pathogens (Noble et al., 2003; Skraber et al., 2004; Harwood
et al., 2005; Haack et al., 2009).
Another group of stressors associated with CAFOs include trace elements, which are
used extensively in the CAFO industry as growth promotants and for therapeutic
purposes, and livestock manures are important sources for release of these elements back
into the environment (Jackson et al., 2003; Bolan et al., 2004). Metals and metalloids of
primary interest include copper, zinc, and arsenic, and to a lesser extent nickel and
selenium. Copper and zinc are used in swine and poultry operations to increase weight
gain (Rea et al., 1999). At higher concentrations, copper also inhibits microbial growth
(Skrivan et al., 2006), and it has also been shown to improve odor characteristics of swine
waste (Armstrong et al., 2000). Copper salts are also used as a footbath in milking yards
to treat lameness in dairy cattle (Bolan et al., 2004). Arsenic, in the form of the
organoarsenical antibiotic Roxarsone, has been used extensively in the poultry industry to
improve weight gain, feed efficiency, and pigmentation, in addition to its use with
ionophores to control coccidiosis (Chapman and Johnson, 2002). To a lesser extent,
Roxarsone has also been used in the swine industry, and has been found in several swine
lagoons (Makris et al., 2008). Roxarsone can be degraded under both aerobic and
anaerobic conditions to release the more toxic inorganic arsenic species which can then
be mobilized and contaminate ground water (Arai et al., 2003; Stolz et al., 2007; Church
et al., 2011). Although the use of Roxarsone is declining in the U.S., this can lead to
legacy contamination events from past practices, as illustrated in the Delmarva Peninsula
where approximately 20-50 metric tons of Roxarsone had been applied yearly (Hileman,
2007).
Pharmaceutical chemicals used in CAFOs include antibiotics and synthetic hormones,
and antibiotics in particular are of concern because of the large volumes that are used as
livestock growth promotants and their potential to confer antibiotic resistance among
-------
commensal and pathogenic microorganisms. Although estimates vary, 40% to 87% of all
antibiotics produced in the U.S. are used in animal feeds to promote growth (Gilchrist et
al., 2007). Veterinary antibiotics vary widely in chemical properties and include many
different sulfonamides, macrolides, fluoroquinolones, B-lactams, tetracyclines, and
aminoglycosides, and also include other chemicals which serve as anthelmintics, or
dewormers (Hailing-S0rensen et al., 1998; Lee et al., 2007). Hence, as might be expected,
different compounds will vary widely with respect to sorption and degradation processes
affecting fate and transport into ground water (Kemper, 2008; Khan et al., 2008). For
example, compounds like tylosin are generally sorbed and rapidly degraded (Hu and
Coats, 2007; Sassman et al., 2007), whereas the sulfonamides are generally more mobile
and, in the case of sulfamethoxazole, more recalcitrant (Wang et al., 2006; Burkhardt and
Stamm, 2007; Barber et al., 2009). Another complication is that antibiotic degradation
products may be almost as potent as the parent compounds, and yet may be more mobile
in soil (Boxall et al., 2003). In addition, there is some evidence that antibiotics like
sulfamethazine and chlortetracycline can be taken up into plants (Kumar et al., 2005;
Dolliver et al., 2007).
There have been relatively few studies on ground water contamination by antibiotics
from CAFOs, in part because of some of the analytical challenges associated with the use
of fairly sophisticated analytical methods and complex matrices such as CAFO lagoon
wastes. However, studies are beginning to emerge that clearly demonstrate the presence
of antibiotics in ground waters associated with beef, dairy, and swine CAFOs (Batt et al.,
2006; Watanabe et al., 2010; Bartelt-Hunt et al., 2011). Perhaps of greater concern is the
potential impact of the high use of antibiotics in CAFOs at subtherapeutic doses on the
prevalence of antibiotic resistance (Pruden et al., 2006; Pruden, 2009a; McKinney et al.,
2010). Numerous recent studies have demonstrated the distribution and prevalence of
antibiotic resistance genes and pathogens at swine (Schroeder et al., 2002; Jindal et al.,
2006; Bibbal et al., 2007; Kozak et al., 2009), dairy (Khachatryan et al., 2006; Sawant et
al., 2007; Srinivasan et al., 2008), poultry (Harwood et al., 2001; Diarra et al., 2007;
Smith et al., 2007; D'lima et al., 2007), and beef (Alexander et al., 2008) CAFOs. Not
surprisingly, we are now starting to see evidence of antibiotic resistance genes and
10
-------
bacteria in impacted ground waters, especially at swine CAFOs (Chee-Sanford et al.,
2001; Koike et al., 2007; Sapkota et al., 2007).
Other concerns involve the natural and synthetic steroid hormones associated with
CAFOs that function as Endocrine Disrupting Chemicals (EDCs) and can interfere with
the normal function of the endocrine system of humans and animals (Ying et al., 2002).
The occurrence of EDCs in surface water is becoming of increasing concern worldwide,
and has led to a growing awareness that animal, and perhaps human, health and function
in ecosystems might become negatively impacted by continued release of EDCs into the
environment (Ashby et al., 1997; Arcand-Hoy et al., 1998). As analytical techniques
have become more robust and more sensitive, natural steroid hormones are now being
detected at trace levels in streams (Kolpin et al., 2002) and in drinking water systems
(Benotti et al., 2009). Natural steroid hormones include estrogens, androgens, and
progestins, which are produced by metabolism and excreted by humans as well as
animals (Arcand-Hoy et al., 1998). Although these compounds can be degraded
biologically, they have been detected in sewage treatment effluents and receiving surface
waters at ng/L levels (Ternes et al., 1999; Baronti et al., 2000; Joss et al., 2004; Shappell,
2006), and in some cases are transported into surface water from contaminated ground
water (Standley et al., 2008). These concentrations are significant, because several of
these steroid hormones are potent EDCs and can exert environmental effects at low ng/L
levels. Hanselman et al. (2003) reported that natural estrogens possess estrogenic
potency up to 10,000 to 100,000 times higher than exogenous EDCs (excluding the
synthetic estrogen 17a-ethynylestradiol, used in birth control pills). Research has shown
that male fish exposed to low ng/L levels of estrogens will exhibit estrogenic responses
such as vitellogenin production (Routledge et al., 1998; Vajda et al., 2008; Shore, 2009a).
Vitellogenein induction has also been observed in female turtles associated with farm
ponds receiving steroid estrogens from direct contact with cattle as opposed to control
ponds with no such contact (Irwin et al., 2001), and in fathead minnows exposed to
runoff from fields amended with poultry litter under standard agricultural practices
(Yonkos et al., 2010). Environmental effects can occur through short-term or intermittent
exposure (Panter et al., 2000; Schultz et al., 2003; Martinovic et al., 2008), or exposure to
11
-------
combinations of estrogens which individually are below their respective action levels
(Silva et al., 2002a; Thorpe et al., 2003; Brian et al., 2007).
CAFOs constitute a source for release of steroid hormones into the environment, whether
these are just produced naturally by the animals or used to promote weight gain, and high
concentrations of natural estrogens are found in CAFO wastes (Arcand-Hoy et al., 1998;
Hanselman et al., 2003; Hutchins et al., 2003; Lorenzen et al., 2004; Raman et al., 2004;
Hutchins et al., 2007; Lee et al., 2007; Shore, 2009b; Bevacqua et al., 2011). The steroid
hormones of particular interest that are endogenously produced and excreted by livestock
include the natural estrogens estrone and 17(3-estradiol. Of these, 17(3-estradiol has the
potential for exerting the greatest environmental impact, although estrone is almost as
potent and in some cases can be converted back to 17a-estradiol or 17(3-estradiol (Czajka
and Londry, 2006). Estimates for the predicted-no-effect-concentration (PNEC) for the
most active natural estrogens in surface water are 1 ng/L and 3-5 ng/L for 17(3-estradiol
and estrone, respectively (Young et al., 2004). It is estimated that estrogen loads from
land application by livestock manure would account for greater than 90% of the total
estrogen in the environment (Khanal et al., 2006), and emissions of estrogens from dairy
and swine CAFOs exceed the mass flow of estrogens from municipal sewage treatment
plants in the United States (Raman et al., 2004). In addition, other research has shown
that estrogens can leach more readily from cow and chicken manure than from sludge
from wastewater treatment plants (Suri et al., 2007). Research with swine manure has
shown that steroid hormone levels can be reduced with additional treatment steps such as
constructed wetlands (Shappell et al., 2007) or an upflow anaerobic sludge blanket with
trickling filter (Furuichi et al., 2006), but by far most swine CAFOs in the United States
store the liquid waste in lagoons and then land apply as needed. Several laboratory
studies have focused on the sorption (Casey et al., 2003; Lee et al., 2003; Das et al., 2004;
Mansell and Drewes, 2004; Casey et al., 2005; Zhou et al., 2007) and biodegradation
(Colucci et al., 2001; Lorenzen et al., 2005; Jacobsen et al., 2005; Lorenzen et al., 2006;
Khan et al., 2008) of steroid hormones in agricultural soils, and in general these studies
show that steroid hormones are readily sorbed and degraded. However, there have been
numerous studies showing that steroid hormones released from animal waste have been
12
-------
measured in both surface waters and ground waters associated with CAFOs (Nichols et
al., 1997; Finlay-Moore et al., 2000; Peterson et al., 2000; Renner, 2002; Hanselman et
al., 2003; Kolodziej et al., 2004; Kolodziej and Sedlak, 2007; Arnon et al., 2008; Zhao et
al., 2010). One problem may be that laboratory studies represent very controlled
environments that may or may not replicate all of the influencing factors found in the real
environment. For example, Sangsupan et al. (2006) demonstrated significant transport of
17(3-estradiol and testosterone in undisturbed soil columns which more appropriately
replicated the macropores found in the real environment at most sites, and Kjaer et al.
(2007) similarly observed increased leaching of estrone and 17(3-estradiol from manure-
treated structured soils into tile drains. Another problem is that steroid hormones are
excreted in either the free form or as sulfate or glucuronide conjugates, depending on the
animal and the route of excretion. Because estrogen conjugates are more polar than the
free forms, they are expected to be more mobile in the soil (Hanselman et al, 2003), and
therefore have a greater potential for impacting ground water. CAFO lagoons have been
found to contain estrogen conjugates as well as free estrogens (Hutchins et al, 2007). The
conjugated forms of these steroid hormones are biologically inactive, but can be readily
deconjugated to produce the active free steroid hormones (Arcand-Hoy et al., 1998;
Ascenzo et al., 2003; Scherr et al., 2008).
In summary, CAFOs have the potential for contaminating ground water with stressors
other than just nutrients. Bradford et al. (2008) recently reviewed the theoretical impact
of land application of CAFO wastewater on agricultural lands and recommended that
additional research focus on whether risk management strategies used to prevent ground
water contamination by nutrients (primarily nitrate) are equally protective with respect to
other contaminants, including steroid hormones. We took a somewhat different approach
to address this issue by posing the following question: if improper design or management
practices at a CAFO results in ground water contamination by nitrate, is this ground
water also contaminated by other stressors in that CAFO waste? These field studies were
therefore conducted to ascertain whether nitrate-impacted ground waters at problematic
CAFO sites were also contaminated with other stressors present in those CAFO wastes.
The primary focus was on estrogen hormones, because of the importance of EDCs as
13
-------
ecological stressors and the lack of information on the contribution of CAFOs to
estrogens in the environment. However, other stressors were also selected for study,
based on expected prevalence and the availability of analytical resources, and the final
analytical suite discussed in this report included nutrients (nitrate, ammonium, and
orthophosphate), natural estrogen hormones (estrone, 17a-estradiol, 17(3-estradiol, and
estriol), microbial indicators (total coliforms, fecal coliforms, and fecal enterococci),
metals and metalloids (arsenic, copper, nickel, selenium, and zinc), and antibiotics
(selected macrolides, quinolines, sulfonamides, tetracyclines, and other antibiotics).
2.0 Materials and Methods
2.1 Field Site Selection Criteria
Seven separate CAFO field sites located in south central United States were selected for
study, including swine, poultry, dairy, and beef operations. These were all commercial
operations and were designated as Large CAFOs based on the number of animals at each
facility. These sites were selected for study because each site, with one exception, had
ground water contaminated with nitrate and/or ammonium, and previous investigations
had either demonstrated or implicated site operations as the source of the ground water
contamination. The exception was a relatively recent swine farrowing sow operation,
which was included as a relatively non-impacted site to ascertain whether off-site wells
which had very low nitrate levels and were downgradient of the site were also free of the
other types of contaminants found in CAFO waste and would therefore provide suitable
background conditions for evaluating any potential future impacts.
It was beyond the scope of this study to try to determine the relative contributions of the
individual source terms to ground water contamination at each site because of limited site
access and resource constraints. In addition, for most sites, ground water samples could
only be obtained from the available facility sampling wells, which often were not
distributed to the extent required for evaluating other source terms within the facilities.
14
-------
In some cases ground water contamination most likely occurred through leakage of
CAFO wastes from lagoons or associated barns and infrastructure, whereas in other cases
excessive land application of CAFO waste effluents was the most likely source.
Additional site information is provided for each site in the individual case studies.
2.2 Stable Isotope Evaluation Criteria
Stable isotopes have been used in previous ground water studies to provide information
on the sources of ground water (Gat, 1971; Blasch and Bryson, 2007) as well as on the
sources of nitrate in ground water (Sidle et al., 2000; Silva et al., 2002b; Jin et al., 2004;
McMahon et al., 2008). Although CAFOs were already identified as the sources of
nitrate in most of these case studies described in this report, we measured the stable
isotopes of water, nitrate, and ammonium in CAFO lagoons and ground waters to
evaluate whether the information could be used in these limited synoptic sampling events
to facilitate the interpretation of the analytical data from these sites.
9 10
Stable isotope ratios of water (5 H-H^O, 5 O-H^O) were used in a very simplified way to
gather additional information about the sources of the ground water samples obtained
from the site wells by comparing the distribution of these two isotopes to the meteoric
water line (MWL) provided by Taylor (1974). The lighter isotopes of hydrogen and
oxygen are lost more rapidly than the heavier isotopes during evaporation of water, but
not proportionately so, and therefore surface water bodies tend to have isotopic ratios that
r\
deviate significantly from the MWL by becoming more depleted in 5 H-H^O relative to
1 &
5 O-H2O. In this study, ground water samples whose isotope ratios fell significantly
below the MWL compared to those which more closely aligned with the MWL were
considered to be more influenced by recharge from an evaporative surface water body.
Evaluation of stable water isotope data provides another generalization that can be made -
if all of the wells at a site have similar screened intervals and the ground water samples
have very similar water stable isotope values, this indicates a very similar ground water
source and recharge history for the wells. Conversely, differences in water stable isotope
values from ground water samples taken from wells with similar screened intervals could
15
-------
mean several things, including the possibilities that a well could be improperly sealed or
that preferential flow paths may exist.
Stable nitrogen isotope ratios of nitrate (515N-NC>3) and ammonium (515N-NH4) were also
analyzed at these field sites. Because volatilization of ammonium from animal wastes
results in an increased fraction of the heavier nitrogen isotope in the residual ammonium
as well as in the nitrate produced from that ammonium, stable nitrogen isotopes of nitrate
and ammonium have been used to indicate whether the source of ground water nitrate
was from fertilizer or from animal waste (Becker et al., 2002; Karr et al., 2003; Widory et
al., 2005). Although ranges vary (Bedard-Haughn et al., 2003; Mariappan et al., 2009),
stable nitrogen isotope ratios (515N) values in sewage and animal wastes typically exceed
+8%o to +10%o, and in general nitrate with a 515N value in excess of+10%o indicates that
sewage or animal waste is the source. One of the factors complicating this interpretation
is that denitrification processes can cause the 515N of the residual nitrate to increase
exponentially as nitrate concentrations decrease (Kendall et al., 2008), and this can lead
to false assignments of animal waste signatures to 5N15 values greater than +10%o.
However, a consequence of this 5N15 enrichment by denitrification is that nitrate
concentrations will decrease as 515N values increase, and this can be used to indicate
whether denitrification processes are occurring. These relationships were used in this
study as follows: 1) a 515N value greater than +10%o for either nitrate or ammonium was
interpreted to be indicative of animal waste, and 2) any observed decreases in nitrate
concentrations correlated with increases in 515N-NC>3 were interpreted as evidence that
significant denitrification was occurring, and that 515N-NC>3 values greater than +10%o
might not be attributable to animal wastes.
18
The stable oxygen isotope ratio of nitrate (5 O-NOs) was also analyzed at these field
sites. Stable oxygen isotopes of nitrate have been used to help determine whether the
source of nitrate derives from atmospheric precipitation, nitrate fertilizers or ammonium
fertilizers, and also to evaluate the contribution of denitrification to enrichment of 515N-
NO3 (Silva et al., 2002; Deutsch et al., 2005; Kendall et al., 2008). Nitrate derived from
1 &
atmospheric sources is more enriched in 5 O-NOs than nitrate found in nitrate-based
16
-------
fertilizers or derived from nitrification of ammonium-based fertilizers, and this can help
to determine the source of nitrate, especially where 515N-NC>3 values are low. An
additional use of stable water oxygen isotope data derives from the fact that
denitrification enriches 518O-NO3 as well as 515N-NC>3, and therefore a positive
correlation between 518O-NO3 and 515N-NC>3 values would be expected under conditions
of denitrification. These relationships were used in a very simplified manner as follows:
10 1C
1) 5 O-NOs and 5 N-NOs values were compared graphically with published ranges
adapted from Silva et al. (2002b) and Kendall et al. (2008) to attempt to discern the
10 1C
sources of nitrate, and 2) a positive correlation between 5 O-NOs and 5 N-NOs values
was interpreted as evidence of denitrification, which could potentially lead to a false
animal waste signature for 515N-NC>3 values in excess of+10%o.
Because there are many factors complicating the interpretation of stable isotope data
(Mengis et al., 2001; Bedard-Haughn et al., 2003; Kendall et al., 2008), these criteria are
not definitive and should be considered as supporting evidence only.
2.3 Field Site Sampling
CAFO lagoon samples were generally taken under vacuum using a stainless steel sample
inlet suspended with a float and connected to a peristaltic pump. In some cases a stainless
steel submersible pump (Grundfos Pumps Corporation, Clovis, CA) equipped with a float
and suspended to a depth representative of effluent intake for land application was used.
Lagoon water was pumped through polyethylene tubing at 500 mL/min through a sample
filter bypass system into a flow-through cell for 15 min prior to electrode measurements
and sampling. Ground water samples were generally taken using an identical, but
separate, stainless steel submersible pump, filter by-pass system, and flow-through cell.
In some cases where well casings were severely bent or pumping infrastructure partially
blocked access, the peristaltic pump was used instead to sample ground water. Contrary
to many common practices, wells were not purged for a specific number of well volumes
prior to sampling. Rather, a low-flow sampling technique was used to ensure minimal
disturbance of the water column and acquisition of representative ground water from the
17
-------
aquifer matrix (Puls and Powell, 1992). Ground water was pumped at a low flow rate
(500 mL/min) and was monitored in-line for pH, oxidation-reduction potential (ORP),
conductivity, temperature, and dissolved oxygen (DO) using the field meter electrodes
(Orion Research, Inc., Beverly, MA) associated with the flow-through cell. Once
conductivity and oxygen readings had stabilized, sample collection began. Sample
collection generally began after about 15 min, but if these parameters had not stabilized
additional time was allotted for purging the sampled well volume. When the sampled
well volume was sufficiently purged, the ground water was diverted past the flow-
through cell and samples were obtained and analyzed on-site for alkalinity, turbidity, and
in some cases dissolved oxygen using field kits (CHEMetrics Inc., Calverton, VA).
Certain unfiltered and filtered samples were routinely taken and transported back on ice
for laboratory analysis, including 1) 60-mL unfiltered samples for analysis of nitrate
(NO3-N), nitrite (NO2-N), orthophosphate (o-PO4), chloride (Cl), sulfate (SO4), total
carbon (TC), total organic carbon (TOC), and total inorganic carbon (TIC); 2) 60-mL
unfiltered samples, acidified with sulfuric acid to pH < 2, for analysis of combined nitrate
and nitrite (NO2/NO3-N), ammonium (NH4-N), total Kjeldahl nitrogen (TKN), total
phosphorus (TP), and TOC; and 3) 30-mL filtered samples, filtered through 0.45|i
syringe filters and acidified with nitric acid to pH < 2, for analysis of metals/cations. For
certain lagoons with high suspended solids, additional unfiltered samples were taken,
acidified with nitric acid to pH < 2, and then digested prior to analysis for metals/cations
to better determine contaminant loading using whole effluents. Calibrated plastic bottles
amended with sodium thiosulfate (IDEXX Laboratories, Inc., Westbrook, ME) were used
to collect 100-mL unfiltered samples for microbial indicator counts. Unfiltered samples
were also collected for dissolved methane (CtL;) and nitrous oxide (N2O) analyses into
each of two 60-mL serum bottles amended with sodium phosphate tribasic dodecahydrate
and sealed with Teflon®-lined grey butyl rubber septa.
For large-volume filtered samples, the sample stream was diverted through a 0.45-ji high-
capacity ground water sampling capsule (Geotech Environmental Equipment, Inc.,
Denver, CO) and 500 mL was collected and discarded prior to sample collection.
9 10
Filtered samples for stable isotopes of water (5 H-H2O, 5 O-H2O) were collected into
18
-------
30-mL plastic bottles and sealed with minimal headspace. Filtered samples for stable
nitrogen isotopes of nitrate and ammonium (515N-NO3/NH4) were collected into 1,000-
mL plastic bottles, and filtered samples for stable oxygen isotopes of nitrate (518O-NO3)
were collected into 500-mL plastic bottles. Filtered samples for estrogen analysis were
collected into 2-L glass media bottles and preserved with formaldehyde (1% final
volume). Filtered samples for antibiotics were collected into each of four separate 125-
mL amber glass bottles. Filtered samples for arsenic speciation were collected into 30-
mL amber plastic bottles and acidified to pH < 2 with hydrochloric acid. Some lagoon
samples could not be filtered on-site and were instead collected into 2-L glass media
bottles and transported back to the laboratory on ice for centrifugation and pressure
filtration.
Extensive sampling and analyses generally occurred for one to three sampling events per
site, although two of these sites were monitored annually for approximately ten years,
albeit for not all analytical parameters. The complete data sets for all sampling events are
provided in Appendix A. Equipment blanks (EQBLK) and field duplicates (FD) were
collected for each sampling event, although not for all parameters each time. Equipment
blanks were prepared by running laboratory reverse-osmosis (RO) water through the
sampling pumps, filter bypass system, and flow-through cell during sampling events.
The frequency of field duplicate collection was approximately 10%. Because a change in
the estrogen hormone analytical method provided greater sensitivity in 2009, these
measures were later expanded to include field blanks (FLDBLK) and multiple equipment
blanks. Field blanks were prepared by pouring RO water directly into sample containers
during sampling events.
2.4 General Laboratory Analyses
Samples which could not be field-filtered (particularly lagoons) required additional
processing in the laboratory. Each lagoon sample was mixed and transferred to 500-mL
centrifuge bottles and centrifuged at 9,000 RPM (13,700 RCF) for 1 h at 4°C. The
supernatants were decanted directly into a 10-L stainless steel pressure tank and the
19
-------
sample was pressure filtered under 40 psi nitrogen through a stainless steel filter holder
containing a 142-mm 0.45|i filter with a 124-mm 0.7|i glass fiber prefilter.
Nutrient and general parameter samples were analyzed by Standard Methods (American
Public Health Association, 2005), whereas metals/cations were analyzed by inductively-
coupled plasma-optical emission spectrometry (ICP-OES). Because high organic carbon
can interfere with arsenic determination by ICP-OES, selected samples were also
analyzed for arsenic by inductively-coupled plasma-mass emission spectrometry (ICP-
MS), and some of these samples were also analyzed for arsenic speciation using ion
chromatography coupled online to ICP-MS as described by Beak and Wilkin (2009).
Arsenic speciation included arsenate (As (V)), arsenite (As (III)), monomethylarsenate
(MMA), and dimethylarsenate (DMA). Dissolved gases were analyzed by exchanging
part of the sample with helium and then measuring gas concentrations in the headspace
with a gas chromatograph after headspace equilibrium was attained. Microbial indicator
counts were performed with a Most Probable Number (MPN) method using the assay kits
Colilert® for total and fecal coliforms and Enteroalert® for fecal enterococci (IDEXX
Laboratories, Inc., Westbrook, ME). Stable isotopes of water were analyzed using a high
temperature conversion elemental analyzer (TC/EA), a continuous flow unit, and an
isotope ratio mass spectrometer (IRMS). The TC/EA reactor contains carbon chips that
are used to react with water at high temperature to generate hydrogen and carbon
monoxide gases. The isotopic composition is reported in permil (%o) relative to Vienna
Standard Mean Ocean Water (VSMOV). The acceptable standard deviations of
replicates and standards for this method are 1.0% and 0.2% for 62H-H2O and 618O-H2O,
respectively.
Outside laboratories were used for the analysis of the other stable isotopes and also for
antibiotics. Following any required centrifugation and pressure filtration for lagoon
samples, these stable isotope samples were immediately frozen and then shipped to the
University of Nebraska's Water Sciences Laboratory (Lincoln, NE). Nitrogen isotopes of
nitrate and ammonium (515N-NO3/NH4) were determined using alkaline distillation of
ammonium, Devardas alloy reduction and separate distillation of nitrate as ammonium,
20
-------
and then oxidation of ammonium to nitrogen gas and dual inlet IRMS (Gormly and
1 &
Spalding, 1979; Krietler, 1979). Oxygen isotope analysis of nitrate (5 O-NOs) was done
separately by ion exchange separation of nitrate and conversion to silver nitrate prior to
high temperature pyrolysis IRMS (Silva et al., 2000). Laboratory duplicates, reference
standards, and blanks were run at a frequency of 5% of total sample throughput (Dan
Snow, personal communication). The measurement quality objective (MQO) for the
measured value of the stable isotope ratios in reference standards was set to within 0.5
permil or less of the nominal value in the calibration standards. Unfiltered samples for
antibiotic analysis were shipped on ice to the U.S. Geological Survey's Organic
Geochemistry Research Laboratory (Lawrence, KS). Samples were filtered and analyzed
by solid phase extraction (SPE) and liquid chromatography mass spectrometry (LC/MS)
as described by Meyer et al. (2007). Water blanks and standard samples were processed
using the same method as the environmental samples. Blanks were analyzed after the last
sample in the standard curve and after every check standard or matrix spiked sample.
Two sample blanks were also interspersed among the environmental samples in each
analytical run. A duplicate and matrix spiked sample was analyzed after every ten
samples in each analytical run and a check standard was analyzed after every twenty
samples in an analytical run. The particular assay used (LCAB analysis) measures
selected macrolides, quinolines, sulfonamides, tetracyclines, and other antibiotics and
Pharmaceuticals (Mike Meyer, personal communication). The complete analyte list,
along with their corresponding reporting limits, is shown in Table 1.
2.5 GC/MS/MS Analysis for Estrogens
Estrogen hormones analyzed in this study include estrone, 17a-estradiol, 17(3-estradiol,
17(3-ethynylestradiol, and estriol. Estrogens were analyzed in ground water and lagoon
samples by solid phase extraction (SPE), pentafluorobenzyl and trimethylsilyl
derivatization, and gas chromatography tandem mass spectrometry (GC/MS/MS) using
electron capture negative ionization. There were three iterations of this method used over
the course of this ten-year study. From 2001 to 2008, samples were analyzed using a 60-
m DB5-XLB capillary column and a Finnigan TSQ-7000 mass spectrometer with

b identifiers are provided only for those compounds that were reported in any of the samples in this study
methane (and then later carbon dioxide) as the chemical ionization reagent gas (Fine et
al., 2003; Hutchins et al., 2007). In brief, ground water and lagoon samples were
collected in the field and preserved with formaldehyde to a final concentration of 1%
(w/v). Ground water samples were normally filtered in the field whereas lagoon samples
were centrifuged and filtered through a 1.2 jim glass fiber filter pad in the laboratory.
22
-------
Volumes used for extraction and analysis were typically 1,000 mL for ground water
samples and 25 mL for lagoon samples. Deuterated analogs of the estrogens were used
as isotope dilution standards (IDS) and were added to both ground water and lagoon
samples before extraction. After the isotope dilution standard was added, the sample was
drawn through an Oasis HLB SPE cartridge using vacuum. The cartridge was washed
with polar solvents to remove highly polar compounds and then the adsorbed estrogens
were eluted with more nonpolar organic solvents. The extract was taken to dryness and
then reconstituted with acetone, after which phenolic functional groups of the estrogen
residue were derivatized with pentafluorobenzyl bromide to make pentafluorobenzyl
ethers. Following an additional evaporation and reconstitution step, any hydroxy groups
present in the estrogens were then derivatized with N-trimethylsilylimidazole to make
trimethylsilyl ethers. The derivatized extracts were then additionally spiked with
derivatized pentafluorobenzyl 7-methylestrone (7-methylestrone-PFB) as a surrogate to
allow monitoring of the performance of the mass spectrometer independent of the
extraction and derivatization processes. The final extracts containing the derivatized
estrogens, deuterated estrogen isotope dilution standards, and derivatized surrogate were
injected onto a GC capillary column and the compounds were then separated and
detected using GC/MS/MS. Multiple procedures were used to assess QA, including the
use of blanks, laboratory replicates, field replicates, and matrix spikes.
This instrument was replaced in 2009 with a TSQ Quantum GC mass spectrometer
(Thermo Fisher Scientific, Inc., Waltham, MA) and the method parameters were
subsequently modified. Instead of the 60-m capillary column used earlier, two 15-m
Zebron® ZB-XLB-HT capillary columns (Phenomenex, Torrance, CA) were used in
series and a Deans switch (Agilent Technologies, Inc., Santa Clara, CA) was installed in
the gas chromatograph to vent the solvent and derivatizing reagents eluting from the first
capillary column away from the ion source. Quantitation of the derivatized estrogens was
accomplished by selective reaction monitoring (SRM) mass spectrometry where one
characteristic ion of the derivatized estrogen, the precursor ion, was filtered through the
first quadrupole (Ql) of the mass spectrometer. Collision-induced dissociation of the
precursor ion occurred in the collision cell where argon and collision offset energy
23
-------
caused the filtered ion to fragment. The most abundant fragment ion, the product ion,
was then filtered by the third quadrupole (Q3). A unique set of SRM ions provided mass
chromatographic peaks for each estrogen and isotope dilution analog. The peak areas
were integrated and the peak area ratios of the target and labeled estrogen were
interpolated into calibration curves allowing determination of estrogen concentration in
the extract and initial sample. With 1,000 mL of ground water sample, 1.0 mL of extract
volume, and the lowest level calibration standard of 1.0 pg/|iL, the quantitation limit (QL)
was 1.0 ng/L in ground water. For a 25-mL lagoon sample, the QL would correspond to
40 ng/L. Recoveries of the five estrogens spiked into 1,000 mL of lab purified water (n =
7) at 2.0 ng/L ranged from 98-101%. Recoveries of estrogens spiked into 100 mL of
dairy lagoon water and 25 mL of swine and dairy lagoon water at 200, 2,500 and 8,000
ng/L ranged from 67-122%. The method detection limits (MDLs) of the five estrogens
for a lab purified water sample volume of 1,000 mL ranged from 0.1-0.3 ng/L.
This method was used in 2009 to analyze estrogen hormones from several different field
sites, which during that same time period were also sampled for antibiotics and stable
isotopes and provide most of the data for this report. However, as more experience was
gained using the new instrumentation, it was also recognized that low-level carryover and
background noise were sometimes resulting in erroneous detections of some analytes,
particularly estrone, at or near the QL (1.0 ng/L). Although this did not affect the
confirmation or quantitation of analytes at higher concentrations (> 5.0 ng/L), it did bring
into question whether analytes detected in the 1.0-5.0 ng/L range were truly present or
represented artifacts. Considerable effort was done to minimize the carryover and
background interferences in early 2010 before conducting additional field sampling.
Background interferences of target estrogens in blanks were reduced by switching the
surrogate from 7-methylestrone to 7-methylestradiol and by decreasing the concentration
of isotope dilution standards that were added to standards, samples and blanks.
Carryover of estrogens into the next sample during extraction was minimized by setting
up separate sample queues for lagoon samples and using extraction apparatus dedicated
to lagoons. The potential for estrogen carry-over and adsorption during SPE was also
minimized by eliminating plastic funnels used to transfer sample to the SPE cartridges,
24
-------
replacing Teflon® sample transfer tubing with Siltek/Sulfmert® stainless steel megabore
capillaries (Restek, Belefonte, PA), and replacing Teflon® solvent guide needles with
stainless steel ones. Derivatization reactions were made more reproducible by using new
sample processing stations (Reacti-Vap III®, Thermo Scientific Laboratories, Inc.,
Waltham, MA) that incorporated magnetic stirrers, centralized heating, and blow-down
units to minimize sample handling. Teflon®-covered magnetic stirring bars were
replaced with glass-covered magnetic stirring bars and reusable glass centrifuge tubes
were replaced with disposable derivatization vials. In the previous GC autosampler
method, a solvent plug was drawn up into the syringe barrel followed by the sample.
This was modified so that instead sample would be drawn into the syringe and expelled
multiple times to thoroughly rinse the syringe and minimize air bubbles. Then, following
sample injection, both the syringe and injector port were flushed by injecting three 8-|iL
volumes of solvent into the injection port. Several additional improvements to the GC
method were made to improve reproducibility and help prevent degradation of the
capillary columns and ion source. These included the use of a Uniliner® injection port
liner (Restek, Bellafonte, PA) that was press-tight sealed to the front of the capillary
column, and pressurized pulse injection for more complete transfer of sample to the
capillary column. High thermal stability capillary columns (Zebron® ZB-XLB-HT
Inferno, (Phenomenex, Torrance, CA)) were used to replace the original capillary
columns, and contamination of the mass spectrometer ion source was minimized by
utilizing a cleaner chemical ionization gas, ammonium, instead of carbon dioxide.
Improvements were also made to better track instrument performance and to increase
confidence in target estrogen identification and quantitation. Instrument stability during
the analysis of a sample queue was followed by acquiring the spectrum of the ion source
calibration gas and a mass chromatogram of an archived derivatized estrogen standard at
the beginning and end of the sample queue. If these fell below stated MQOs at the
beginning of the sample queue, the sample queue was stopped to preserve sample
integrity while the underlying causes are addressed. The confidence in target estrogen
identification and quantitation was improved by adding three or four additional MS/MS
precursor/product ion pairs to the acquisition parameter list for each target estrogen and
25
-------
by establishing MDLs and calibration curves for each of the ion pairs. The sum of the
ion pairs was normally used for quantitation, but this was often not possible in cases
where matrix interferences masked the response of one or more of the ion pairs. This
improvement allowed quantitation using those ion pairs unaffected by matrix peaks. In
addition, evaluation of the relative intensities of the ion pairs provided additional
confirmation of analyte identity and also allowed a calculation of index match between
standards and samples. With these improvements, the MDLs of the five estrogens in
1,000-mL water samples ranged from 0.02-0.07 ng/L, and the QL was lowered to 0.25
ng/L. An example of the use of these methods is provided in Appendix B, which is an
analytical report for one of the sites sampled in 2011. This report also shows data from
field replicates, laboratory replicates, equipment blanks, laboratory blanks, derivatization
blanks, extraction blanks, and matrix spikes, which were run with every sample set that
was analyzed.
3.0 Summary Case Studies
Seven separate case studies are presented, including a swine finisher operation, a poultry
layer operation (since closed), a swine nursery operation, a dairy operation, a combined
swine operation (since closed), a beef feedlot operation, and a swine farrowing sow
operation. With the exception of the swine farrowing sow operation, which served as a
relatively non-impacted site, each of these case study sites exhibited ground water
contamination by nitrate and/or ammonium. For most sites, this most likely resulted
directly from the operation, either through leaking infrastructure piping, leaking lagoons,
or land application of CAFO waste. Sampling events during 2001-2011 ranged from
one-time (snapshot) to periodic, with some sites being sampled annually or even more
frequently. Only the most relevant sampling events are described in these case studies,
and only part of the data from these sampling events are presented in this report; the
remainder of the data from these sampling events are provided in Appendix A.

-------
3.1 CAFO Site #1 - Swine Finisher
Case Study Summary. This site was only sampled once, and in a way represents the most
problematic of all of the sites in this report, having a complex hydrogeology that leads to
problems in data interpretation. Ground water nitrate concentrations ranged up to 45
mg/L NOs-N, and, although the source is not definitive, likely resulted from leaking
lagoons and/or CAFO barn and piping infrastructure. Few additional stressors were
detected in ground water at this site, other than the antibiotic lincomycin which was
found at low levels in several wells. Estrogen hormones were not detected in ground
water, with exception of one detection of estriol in one well replicate sample at 1.6 ng/L.
Site Description. CAFO Site #1 is a swine operation that began in April 1983 as a swine
finisher, raising pigs from 40-60 Ibs up to a market weight of 260-285 Ibs. In May 1999,
it switched to a swine nursery, raising pigs from about 15 Ibs up to a weight of 40-60 Ibs.
In May 2004 it switched back to a swine finisher and was licensed for 16,320 hogs
distributed among 20 barns. Waste from the barns flows into primary lagoons and then,
where available, secondary lagoons. The lagoons are unlined, but are constructed in
heavy clay. Effluent used for land application is pumped from the terminal lagoon for
each set of barns to several spray heads installed in fields around the facility which are
used for grazing or grass production and baling. The total acreage receiving effluent is
approximately 300-500 acres, depending on the season. The topsoil is a thin layer of silty
clay loam underlain by heavy clay and fractured shale. There were no monitoring wells
associated with the land application areas, and so this site investigation was limited to the
lagoons as well as the monitoring wells around each barn lagoon complex (Figure 1).
Ground water, where found, is in shallow fractures located within the clay and shale
matrix. It was not possible to determine regional ground water flow direction at this site,
but a rough estimate was provided locally for each barn lagoon complex in 1999 by
triangulation of water levels from each of three monitoring wells installed for each barn
lagoon complex (Dan Fairish, personal communication), and these are shown in Figure 1.
For this case study, sampling of the terminal lagoons (LAG1, LAG3, and LAG4) used for
land application was conducted in late March 2009. Lagoon LAG2 was empty and could

not be sampled. The wells were sampled in early April 2009. Several of the monitoring
wells were either dry or produced water so slowly that adequate volumes could not be
obtained for all of the analyses (9 liters total required).
General Chemistry and Stable Isotope Interpretation. Figure 1 shows the orientation of
the wells with respect to the lagoons, and illustrates which lagoons and wells had either a
nitrate or ammonium stable nitrogen isotope 515N value that exceeded +10%o and that
therefore represented an animal waste signature as defined in this study. Table 2 shows
the well water levels, well screened intervals, and general chemistry parameters for each
of the wells and lagoons sampled, and Table 3 shows corresponding values for reactive
nitrogen (nitrate, nitrite, nitrous oxide, and ammonium) as well as the stable isotope
information for nitrate, ammonium and water. As expected, lagoons were high in
ammonium (950-3,190 mg/L NH4-N) with 615N values exceeding +10%o (Table 3). Well
ST5 had a nitrate concentration (12.8 mg/L NOs-N) that exceeded the MCL for nitrate,
but did not have a discernible animal waste signature based on 515N (+4. l%o). In contrast,
wells ST1, ST4, ST6, and ST10 had nitrate concentrations ranging from 23 to 45 mg/L
NO3-N (Table 3), and these all showed animal waste signatures (615N-NO3 > +10%o).
Three of these four wells were located between the barns and the associated lagoons, and

-------
the directions of ground water flow at these three locations implies that the source of
ground water contamination may be from the barns or piping out to the lagoons rather
than from the lagoons themselves. However, there were several anomalies at this
particular field site complicating this interpretation. First, because chloride is a
conservative tracer and is found at high levels in these lagoons (Table 2), it would be
reasonable to expect a positive correlation between ground water nitrate and chloride
concentrations if CAFO waste was the source of the nitrate. Although there is a weak
r\
positive correlation (r = 0.2939) between nitrate and chloride concentrations for these
r\
wells, there is actually a weak negative correlation (r = -0.1497) when all of the wells are
considered. In fact, well ST9 had the lowest nitrate concentration (< 0.01 mg/L NOs-N)
and the highest chloride concentration (3,730 mg/L Cl). This well also showed some
evidence of poor integrity, based on the observation that ground water was difficult to
filter due to suspended grey colloidal material which probably originated from bentonite
used to seal the well casing. Regardless, even excluding this well, there was still no
correlation between ground water nitrate and chloride levels. An argument could be
made that, for some wells, nitrate concentrations were reduced through microbial
denitrification, but neither the general chemistry nor the stable isotope data provide any
evidence to support this. Nitrite and nitrous oxide are produced as intermediates of
microbial denitrification, and levels of both of these were very low in all of the wells at

this site (Table 3). Stable isotope relationships can also be used to look for evidence for
denitrification (Figure 2). For example, Figure 2a shows the relationship between 515N-
values and nitrate concentrations for the wells in which nitrate was detected. If each
well had the same source of nitrate and if denitrification was occurring, there should be a
negative correlation between 515N-NC>3 values and nitrate concentrations. In this case,
there is instead a positive correlation (r2 = 0.7173) between these two parameters (Figure
2a). Furthermore, if each well had the same source of nitrate and if denitrification was
1C 1O
occurring, there should be a positive correlation between 5 N-NOs and 5 O-NOs values.
r\
Instead, there is actually a weak negative correlation (r = -0.0720) between these two
parameters (Figure 2b). These data do not support the possibility that denitrification is
significantly enriching the 515N signature, and therefore it is likely that the observed
enriched 515N values are correctly indicating that the nitrate found in these wells is
derived from animal waste, with swine CAFO waste being the most probable source.
Figure 2b also provides some general ranges expected for different sources of nitrate, and
most of the ground water samples from these wells indicate an animal source. Well ST10
1 R
falls well below these expected ranges due to depletion of 5 O in the nitrate, and the
reason for this is not clear. As noted previously, there are many factors complicating the
interpretation of stable isotope data (Mengis et al., 2001; Bedard-Haughn et al., 2003;
Kendall et al., 2008).
In contrast to stable isotopes of nitrate, stable isotopes of water were used to try to
provide some additional information about the recharge history of the ground water
samples collected from these wells. Figure 2c shows the relationship between the
meteoric water line (MWL) and the stable isotopes of water in these wells and lagoons.
Values further below the MWL are more indicative of water showing evaporative losses.
Thus LAG1, a secondary lagoon which should exhibit more evaporative losses than a
primary lagoon, is more enriched in 518O-H2O and lies further below the MWL than the
two primary lagoons LAG3 and LAG4 (Figure 2c). Interestingly, ground water from
well ST3 also shows an evaporative signature, and it might seem reasonable to assume
that it is due in part to leakage from the adjacent lagoon LAG1 (Figure 1). However,
well ST3 shows no sign of impact from CAFO wastes, and there is no other adjacent

surface water body, and so the reason for this evaporative signature is not clear. Also
I O
note that ground waters from wells ST3 and ST6 have greater 5 O-H^O values compared
to those of the other wells (Figure 2c). This indicates that these two wells are in some
way different with respect to their history of recharge, since the values of 518O-H2O in
rainfall can vary widely depending on the season and other climatic factors (Harvey and
Welker, 2000; Liu et al., 2010). Because these are all very shallow wells screened very
near to the surface (Table 2), it might also indicate preferential flow through faults or
down well casings in these two particular wells. This can easily occur during dry years
through soft faulting in the heavy clay, which might help explain why well ST6, located
only about 30 ft from ST5, has a water table that is over eight ft higher even though both
wells are screened across the same intervals (Table 2). Regardless of the exact reason,
the water stable isotope data show that these two wells are somehow different than the
others with respect to recharge history, and more sampling events at different times of the
year would be needed to determine whether these differences are consistent and whether
transient contaminant events may have been missed.
Evaluation of Additional Stressor Impact. A few other stressors were identified in
nitrate-impacted ground water at CAFO Site #1, but in most cases detections were
sporadic and/or concentrations were low. Ground water orthophosphate concentrations
ranged from 0.018-0.176 mg/L PO/t-P and were not correlated with nitrate concentrations
(r2 = -0.0270). Microbial indicator numbers were quite low in almost all of the wells,
except for well ST5 where very high numbers were recorded for total coliforms, fecal
coliforms, and fecal enterococci (Table 4). The reason for this is not clear, since the
ground water for this well was relatively low in chloride (70.6 mg/L Cl), had only
moderate levels of nitrate (12.9 mg/L NOs-N), and did not exhibit an animal waste
signature, with a 515N-NC>3 value of only +4. l%o (Tables 2-3). It is possible that the total
coliform counts could have been biased high, since the IDEXX method used in this study
is a most-probable-number method and has been shown to overestimate total coliform
numbers by several fold in surface waters compared to standard membrane filtration
methods (Griffith et al., 2006). Regardless, well ST5 also had very high numbers of fecal
enterococci (Table 4), and fecal enterococci counts have been shown to be comparable

"Values reported as "<" are below detection limits
across those methods (Griffith et al., 2006). Well ST5 also had fairly high levels of fecal
coliforms, and these counts tend to be actually somewhat lower than those obtained with
standard membrane filtration methods (Francy and Darner, 2000). It is therefore unlikely
that the MPN method used in this study significantly underestimated the numbers of fecal
coliforms and fecal enterococci in the ground water sample from this well, and so the
source remains unknown. Concentrations of metals and metalloids were also low in these
ground water samples, with the possible exception of selenium, which ranged from 47-
121 |ig/L Se (Table 4). This may represent natural sources of selenium in the soil, since
r\
ground water selenium levels did not correlate with nitrate levels (r = -0.0007). Arsenic
was not detected in ground water using ICP-OES (< 6 |ig/L As), and a more rigorous
analysis by ICP-MS confirmed that arsenic levels were quite low (0.8-4.6 |ig/L As).
What little arsenic was found in the lagoons was generally present as As (III) and, to a
lesser extent, DMA (Appendix A). Veterinary antibiotics were found in the lagoons at
high levels and included lincomycin along with several tetracyclines, but only lincomycin
was detected in the ground water samples (Table 5). Ground water lincomycin
concentrations were quite low (< 5-55 ng/L) and represented a 105-106 decrease
compared to lagoon concentrations. Although these low concentrations were often close
to the reporting limits, lincomycin was detected in three of the five nitrate-impacted wells
and probably represents a low-level contamination event originating from the swine
waste. Note, however, that lincomycin was also detected (47 ng/L) in Well ST3, which

shows no nitrate contamination (Table 3), and the reason for this is unclear. As discussed
earlier, the water stable isotope data show this well to have a stronger evaporative
signature than the other wells, indicating a very different recharge history, and it is
possible that there could have been a contamination event which was missed in this
sampling period. In a separate study, lincomycin was also the only antibiotic detected in
ground water samples impacted by a swine CAFO in North Carolina (Harden, 2009).
Estrogen hormones were also found in these swine lagoons, but at concentrations much
lower than those found for antibiotics (Table 6). The estrogen levels in the swine finisher
lagoons are very similar to what had been observed for a separate swine finisher lagoon,
although here concentrations of estriol were about seven times lower (Hutchins et al.,
2007). There was severe matrix interference with the analysis of 17a-ethynylestradiol in
these lagoon samples, and these results are flagged with the data label "NC" (not
confirmed). This does not mean that this compound was detected. A peak eluted in the
mass chromatogram at the correct retention time as this compound, but the relative
intensities of the MS/MS ion pairs of the sample did not match that of the standards, and
it cannot be determined whether or not this compound was present. An estimate of the
concentration of the unconfirmed peak is included in the data label, and if 17a-
ethynylestradiol is hidden within this unconfirmed peak, its concentration will be less
than this estimate. Because 17a-ethynylestradiol is a synthetic hormone used exclusively

site, with the exception of estriol which was detected at 1.6 ng/L in only one of the field
duplicates for well ST4 (Table 6). This is near the quantitation limit for this compound
(1.0 ng/L), and it was not detected in the other field duplicate. Collectively, these data
provide few indications of ground water contamination at this site by stressors other than
nitrate, with the exception of very low levels of the antibiotic lincomycin.
3.2 CAFO Site #2 - Poultry Layer (Closed)
Case Study Summary. Even though this site also exhibits a complex hydrogeology, here
there is evidence for direct impact to ground water from unlined leaking lagoons.
Impacted ground waters were contaminated by ammonium as well as nitrate, and ranged
up to 32 mg/L NH4-N and up to!29 mg/L NOs-N. Few additional stressors were detected
in ground water at this site, and these generally occurred only at very low levels and were
not consistent with separate sampling events. The estrogen hormone estrone was
detected at a very low level (1.1 ng/L) in one ground water sample in 2009, but not in the
duplicate ground water sample taken from that same well (< 1.0 ng/L). Estrone was also
detected in another well (2.7 ng/L) in 2011. The antibiotic lincomycin was also detected
(34 ng/L) in one of these wells along with estrone. This operation had been closed and
the lagoons had been decommissioned prior to the installation and sampling of the

might have been higher had these lagoons still been in use.
Site Description. CAFO Site #2 was a wet (i.e., lagoon) poultry layer operation that
began in 1971 with about 365,000 chickens distributed among six barns (Figure 3).
Waste from the barns flows into primary lagoons LAG1 and LAG2, with overflows being
diverted to secondary lagoon LAG3 as needed. Effluent used for land application was
pumped from lagoon LAG2 to a center pivot located south of the lagoons onto a
bermudagrass pasture, and at times a reel gun was used to distribute effluent on
pastureland north of the lagoons. Ground water, where found, is in shallow
unconsolidated zones and fractures located within the granite bedrock. One barn was still
operational in early 2006 when lagoon samples were first obtained for steroid hormone
analysis (Hutchins et al., 2007), but the site was later decommissioned and the lagoon
contents were cleaned out by late 2007. The lagoons now primarily serve as catchment
basins for rainwater and runoff. Because no liner was observed during decommissioning
of the lagoons and there was no certification of a lack of hydraulic connection between
the lagoons and the underlying ground water, four monitoring wells were constructed
around the lagoons in 2008 to assess ground water impacts. No monitoring wells were
available to assess ground water impacts from previous land application practices at this
site.
General Chemistry and Stable Isotope Interpretation. We sampled one of the operational
lagoons in 2006, all three decommissioned lagoons and the recently-constructed
monitoring wells in 2009, and the monitoring wells again in 2011 (Table 7-8). Site
operations showed a direct impact on ground water as evidenced by relatively high
ammonium concentrations in downgradient wells GR2 and GR3 during both sample
events (Table 8), and this most likely occurred from previous leakage of CAFO poultry
waste from the lagoons. Samples taken in 2006 from three locations in the operational
lagoon LAG2 showed high ammonium levels (281-302 mg/L NFLj-N) with a strong
animal waste signature (+27.8%o to +28.6%o 515N-NH4), and the ammonium in ground
water samples taken from these two wells in 2009 also showed a strong animal waste

application rates were excessive. Nitrate was also detected in ground water samples
taken from these two impacted downgradient wells, but with variable results between the
two sampling events (Table 8). Ground water nitrate concentrations at well GR2
increased from 10.4 mg/L NO3-N in 2009 to 23.1 mg/L NO3-N in 2011, whereas the
corresponding concentrations in well GR3 dropped from 129 to 0.60 mg/L NOs-N.
There were also significant changes in ground water chloride concentrations between
2009 and 2011 for three of the four monitoring wells (Table 7), and there was no
r\
correlation (r = - 0.0040) between ground water nitrate and chloride concentrations.
Nitrate was not only detected in the ground water samples from the two impacted
downgradient wells, but also in those from the upgradient well GR1 (Table 8), and
isotope analyses conducted in 2009 showed that ground water samples taken from all
three of these wells exhibited an animal waste signature (+20.8%o to +40.7%o 515N-NC>3).

b One of three sampling locations in this lagoon
0 Values reported as "<" are below detection limits
One explanation for this might be that when the lagoons were decommissioned in 2007,
the solids were spread in the area where this upgradient well was later constructed.
In one respect, there is no need to evaluate whether denitrification processes are enriching
515N-NC>3 values and leading to a false animal waste signature, because high 515N-NH4
values were also observed, and this signature would be unaffected by denitrification.
However, it is of interest to determine whether denitrification processes are active and
therefore might facilitate nitrate removal from the contaminated ground water. The
ground water environment reflected in the impacted wells GR2 and GR3 is low in DO
and high in TOC, conducive for denitrification, and in fact there is evidence of this, based
on the very high nitrous oxide level observed in the 2009 ground water sample from well
GR3 (Table 8). Stable isotope relationships also provide some evidence for this (Figure
4). There is a moderate negative correlation (r2 = -0.3612) between 515N-NO3 values and
nitrate concentrations (Figure 4a), and a strong positive correlation (r2 = 0.7811) between
615N-NO3 and 618O-NO3 values (Figure 4b), both of which could indicate that
denitrification is occurring, but the data are too few to attach strong significance to these

particular observations. Collectively, these data show that denitrification may be
occurring in the contaminated ground water, but it is not known whether this will
significantly reduce nitrate concentrations over time. Organic carbon or other electron
donors may not be available at the levels needed to continually support denitrification as
the sorbed ammonium is nitrified to nitrate.
Similar to Site #1, the water stable isotope data at this site show that the surface water
1 &
lagoons have an evaporative signature and again there is a wide range of 5 O-H^O
values (Figure 4c). These are very shallow wells constructed in a fractured matrix, which
can lead to very different rates of recharge. Evidence of this can be seen in the changes
in the water table as measured in the individual wells (Table 7). Wells that have similar
histories of recharge would be expected to show similar changes in water table elevations
over time, whereas in these wells the differences in water table elevations from 2009 to
2009 range from 0.1 ft in well GR4 to 3.2 ft in well GR1. These data highlight the
probability that the presence of specific contaminants can be very transitory in these
wells once the original sources (ie, CAFO wastes in the lagoons) have been removed.
Evaluation of Additional Stressor Impact. Surprisingly, even though direct leakage from
the lagoon caused ground water contamination by ammonium as well as nitrate, there was
little consistent evidence of additional stressors in the impacted wells. Ground water
orthophosphate levels were very low (0.019-0.041 mg/L PO/j-P) and were not correlated
with nitrate levels (r2 = 0.0000). Fecal coliforms and fecal enterococci were not detected
in any of the 2009 ground water samples, although total coliforms were found in
moderate numbers in well GR3 (Table 9), which also had the highest nitrate
concentration at that time (Table 8). Metals and metalloid concentrations were relatively
low in the operational primary lagoon LAG2 sampled in 2006, and ground water
concentrations were generally low in samples taken in 2009 and 2011. Arsenic
concentrations, as measured by ICP-OES, appeared to be moderately high (up to 169
Hg/L As) in some of the wells sampled in 2009, but this may be due to background
interferences, since analysis by ICP-MS showed arsenic concentrations to be less than 5
|ig/L in these same ground water samples (Table 9). Because this was a poultry layer

rather than a poultry broiler operation, it is not likely that the arsenical antibiotic
Roxarsone® was ever used, and arsenic concentrations in lagoons would therefore be
expected to be low. Ground water selenium concentrations were moderate (26-113 |ig/L)
and could be derived from natural sources in the soil, since selenium concentrations were
actually higher in ground water than in the original lagoon (Table 9). The only veterinary
antibiotics found in the operating lagoon LAG2 in 2006 were isochlortetracycline and
epi-isochlortetracycline, and these were only detected in one or two of the three locations
sampled in this lagoon and at levels close to the reporting limit (Table 10). Regardless,
these determinations seem plausible based on the fact that these compounds are the
principal metabolites of chlortetracycline in hen's eggs (Kennedy et al., 1998).
Lincomycin was detected at low concentrations (30-38 ng/L) in both of the field
duplicates for well GR2 in 2009, even though it was not detected in lagoon LAG2 during
2006. Estrogen hormones were detected in the operational lagoon LAG2 in 2006, with
good reproducibility among the three locations sampled (Table 11). Again estrone was
the predominant estrogen found, followed by estriol and then 17a-estradiol; l?p-estradiol
was at or below detection limits for these lagoon samples. Estrone was the only estrogen

detected (1.1 ng/L) in the 2009 ground water samples, but only for well GR2, and this
occurred just above the quantitation limit (1.0 ng/L) and was not confirmed with the field
duplicate (Table 11). With improvements in the analytical method, these wells were
again sampled in 2011, and estrone was again detected in duplicate samples from GR2,
although at levels (0.21-0.23 ng/L) below the quantitation limit (Appendix B). This time,
however, estrone was also detected (2.7 ng/L) in well GR3 (Table 11). Although these
detections are strongly supported by tighter quality controls and transition ion profiles
(Appendix B), these concentrations are still quite low and are less than the predicted-no-
effect-concentration of 3-5 ng/L for estrone (Young et al., 2004). These data show that
leakage of CAFO wastes from the unlined lagoons resulted in ground water
contamination by both nitrate and ammonium, but only in a few instances could the other

3.3 CAFO Site 3 - Swine Nursery
Case Study Summary. Most of our research has focused on this site, and a full site
investigation will be published separately. Ground water contamination by nitrate has
been conclusively linked to land application of liquid swine waste at this site, and EPA
enforcement actions have brought about changes in land management practices which
have caused ground water nitrate levels in the closest monitoring wells to slowly drop
from a high of about 120 mg/L NO3-N in 2006 to about 30 mg/L NO3-N in 2011
(unpublished data). Based on multiple sampling events, there were essentially no
additional stressors detected in ground water at this site, including antibiotics and
45
-------
estrogen hormones. The only exception was estrone, which was detected in two well
samples at very low levels (1.6-2.4 ng/L) during only one of three sampling events in
which ground water samples were analyzed for estrogens.
Site Description. CAFO Site 3 is a swine nursery operation that was started in June 1995
and houses 21,000 feeder pigs distributed among four barn/lagoon complexes (Figure 5).
Each lagoon is constructed with a synthetic liner and receives swine waste directly from
its associated barns without any additional treatment. The lagoon effluents are disposed
by land application through a center pivot over approximately 80 acres of grasses, and
sometimes other crops, used for grazing and/or feed production. The soil matrix consists
of thin dunes of fine to loamy sand overlying an unconfined alluvial aquifer with the base
of the aquifer terminating in red bedrock 60-70 ft below ground surface. Intermittent
clay lenses are found within the vadose zone, and the depth to ground water ranges from
20-30 ft. A wildlife management unit is located just one mile downgradient of the land
application area, and there were concerns that ground water could become contaminated
and ultimately discharge into a series of wetlands within this unit.
Unlike the situation with the other case studies, we were granted routine access to private
lands surrounding this facility and were therefore able to conduct a thorough subsurface
site characterization. Based on the information obtained, we constructed several
monitoring wells both upgradient and downgradient of the land application area screened
at different levels within the aquifer. Generally, two wells were constructed at each
location, with the shallow well (designated with an "A" suffix) screened across or just
beneath the water table and the deeper well (designated with a "B" suffix) screened just
above the bedrock base of the aquifer (Figure 5). Wells were situated in transects
roughly parallel to the flow of ground water so that changes in ground water quality
could be monitored as ground water moved south underneath the land application area
and continued on towards the wetlands. Quarterly monitoring of these wells began in
2000 and was conducted for two years, and then annual sampling has been conducted
since that time. Limited site access was also allowed for lagoon sampling in 2002 and
2007. Because early data showed that over-application had resulted in ground water

contamination by nitrate in wells immediately downgradient of the land application area,
several corrective actions were taken in 2002 leading to a substantial decrease in the
amount of manure nitrogen applied to this field. Since then, there has been a low decline
in ground water nitrate levels immediately downgradient of the land application area
(unpublished data). This decline began in 2006 and continues to present day.
General Chemistry and Stable Isotope Interpretation. For brevity, these discussions focus
on the 2007 data for the lagoons and the 2009 data for the wells (Tables 12-13), since this
is generally when additional samples were analyzed for stable isotopes and the other
stressors. Unlike the situation with the two previous case studies, interpretations were

pretty straightforward with this site. The four swine nursery primary lagoons all had high
ammonium levels (664-879 mg/L NELj-N) with animal waste signatures ranging from
+13.4%o to +17.6%o 515N-NH4 (Table 13). Land application resulted in increases in
ground water concentrations of chloride (Table 12) and nitrate (Table 13) in both the
shallow and deeper wells immediately downgradient of the land application area
compared to upgradient wells. Ground water samples from several of these wells showed
animal waste signatures (515N > +10%o) similar to those of the applied ammonium
9
(Figure 5). There was no correlation (r = 0.0002) between ground water nitrate and
chloride levels across this site, but this was only because of very high chloride levels in
ground water samples from the shallow wells CA11A and CA12A (Table 12). The

reason for this is unknown, and the ground water samples from these two wells also
showed very high levels of sulfate compared to those from all of the other wells. The
swine CAFO lagoon waste is very low in sulfate, and it is unlikely that this is the cause of
the high chloride levels found in the ground water samples from these two wells. If the
results from these two wells are excluded, there is a good correlation (r2 = 0.7878)
between ground water nitrate and chloride levels across this site. This nitrate plume has
been slowly migrating south and is currently impacting the next well transect (CAS,
CA6). There are definitive animal waste signatures as indicated by increased 515N values
in the deeper wells downgradient of the land application area, and these values do not
appear to be caused by denitrifying activity. Ground water DO levels are moderate to
high whereas TOC levels are generally low, which is not conducive to denitrification
(Table 12), and concentrations of both nitrite and nitrous oxide were very low across the
site (Table 13). Denitrification is also not indicated by stable isotope relationships
(Figure 6). In fact, there was actually a strong positive correlation (r2 = 0.7381) between
ground water nitrate concentrations and 515N values (Figure 6a), contrary to what would
18
be expected based on denitrification. There was some observed enrichment in 5 O-NCb
with increasing 515N-NC>3 values which could indicate denitrification (Figure 6b), but this
correlation was weak (r2 = 0.1700). In general, then, nitrate concentrations in this ground
water are expected to persist. Ground water chemistry was not influenced by selective
rapid recharge events at this site, in part due to the relatively uniform sand matrix and the
increased isolation of well screens from surface effects, and therefore ground water
samples from these wells were very uniform with respect to water stable isotope ratios
(Figure 6c).
Evaluation of Additional Stressor Impact. Additional CAFO swine waste stressors were
generally not detected in any of the ground water samples at this site, even with multiple
sampling events. Ground water orthophosphate levels were somewhat high and ranged
from 0.044-0.262 mg/L PO4-P (Table 12), but these levels did not correlate with either
nitrate (r2 = -0.0288) or chloride (r2 = -0.0269) levels. The highest orthophosphate
concentrations were generally found in the deeper ground water samples, and this was
observed upgradient as well as downgradient of the land application area (Table 12).

Microbial indicators were not monitored in 2009, but data from the 2011 sample event
showed that numbers were very low, with the exception of the ground water sample taken
from well CA4B, which had a moderately low count of 26 cells/100 mL for fecal
enterococci (Table 14). Metals and metalloid concentrations were also very low in
ground water at this site. Arsenic concentrations, as measured by TCP-MS, were low in
the original swine lagoons (< 10 |ig/L), and correspondingly arsenic concentrations were
below 5 |ig/L in all ground water samples (Table 14). What little arsenic was found in
the lagoons was generally present as As (V) and, to a lesser extent, DMA (Appendix A).
All other monitored metals and metalloids were at or near the detection limits, except for
Table 14. CAFO Site #3 Microbial Indicators, Metals, and Metalloids.

selenium which was found at low levels (46-58 |ig/L) in ground water samples from the
same two wells (CA11 A, CA12A) having the abnormally high chloride and sulfate levels
noted earlier (Table 14). Antibiotics were analyzed in these nursery swine lagoons in
2002 as well as in 2007 and were found at relatively high levels (Table 15), similar to
what was observed for the CAFO Site #1 finisher swine operation. However, there were
major differences in the types of antibiotics found and the ranges in concentrations from
one sample event to the next, and in some cases there was considerable variation between
the four lagoons even within the same sampling event (Table 15). These data imply that

multiple sample events are needed to get good estimates of the loading of antibiotics
during land application of swine CAFO wastes. Regardless, none of these or any other
antibiotics were detected in the ground water samples collected during the sampling
events in 2002, 2007, and 2009 from selected wells expected to represent either
background or the most impacted ground water conditions (Table 15). Estrogen
hormones were also detected in these lagoons, although at relatively low levels, and these
levels were fairly consistent from one sample event to the next (Table 16). These
concentrations are similar to what was observed for a separate swine nursery (Hutchins et
al., 2007). However, none of these hormones were detected in selected ground water
samples from four separate sampling events, with the exception of low levels of estrone
that were detected (1.6-2.4 ng/L) in downgradient wells MW2 and CA3B in 2009 (Table
16). These wells were again sampled the following year and estrone was not detected in
any of these wells (Table 16). Hence, even though ground water was contaminated with
nitrate from land application of CAFO waste at this site, there was little evidence of
ground water contamination by the other stressors measured in this study.
3.4 CAFO Site 4 - Dairy
Case Study Summary. This is another site where land application of CAFO waste
resulted in contamination of ground water by nitrate, this time through over-application
of dairy lagoon effluent. Ground water nitrate concentrations ranged up to 150 mg/L
NOs-N, and over half of these samples showed animal waste signatures (515N > +10%o).
There was only one complete sampling event for this site, and in most cases again there
were few additional stressors besides nitrate detected in the impacted wells. However,
there were isolated cases where other stressors were detected, sometimes at significant
levels. This was true primarily for ammonium (up to 1.6 mg/L NELj-N) and microbial
indicators (up to > 2,420 cells/100 mL). The antibiotic sulfamethazine was found in one
ground water sample at a low level of 11 ng/L, which is slightly above the reporting limit
(5 ng/L). Estrone was found in two ground water samples at very low levels of 1.0-1.4
ng/L, which are at or just above the quantitation limit (1.0 ng/L). When these latter two
wells were sampled again two years later, estrone was not found (< 0.3 ng/L).

Site Description. CAFO Site 4 is a dairy operation that was permitted in May 1999 for
3,500 dairy cows, along with 5,000 dry cows and calves. Manure is flushed through two
sand filters and then sequentially through four lagoons. The first three lagoons (LAG1-3)
are unlined, and effluent was originally pumped from LAGS several miles east to center
pivots for irrigating corn, soybean, and other crops used for feed (Figure 7). The facility
actually used only about 600 acres of the 3,625 acres permitted for land application, and
ground water was subsequently impacted through over-application. Corrective actions
were taken and a fourth lagoon (LAG4) was constructed with a synthetic liner and used
to bring total storage into compliance. Starting in June 2006, effluent application to these
fields was discontinued. The topsoil in these fields is a mixture of sands and clays, and
the aquifer consists of shallow unconsolidated riverine sands associated with an adjacent
56
-------
river, and is underlain by hard shale bedrock approximately 40 ft below ground surface.
Ground water flow is generally to the east towards the river, which is located just off of
the map shown in Figure 7, and the river flows towards the north. Compared to the
previous case studies, this site covers a very large area and in this case the direction of
ground water flow becomes more uncertain further away from the land application areas.
Well construction logs were not available for this site, but the monitoring wells were
reported to have 15-ft to 20-ft screens and were screened across the water table. Two
irrigation wells were also sampled, one of which (ARWOW) was clearly poorly sealed
and subject to surface effects.
General Chemistry and Stable Isotope Interpretation. General chemistry parameters,
reactive nitrogen, and stable isotope data are shown in Tables 17-18. These dairy lagoons
had moderately high levels of ammonium (124-203 mg/L NELj-N), with concentrations
dropping as lagoon effluent flowed from LAG1 to LAG4 (Table 18). Correspondingly,
515N-NH4 values increased from +10.7%o to +14.0%o due to preferential volatilization of
the lighter nitrogen isotope (Table 18). Most of the wells within and adjacent to the land

application areas had moderate to high nitrate values (15-150 mg/1 NOs-N) and retained
this animal waste signature (> +10%o 515N-NO3), but there were a few exceptions. Wells
further downgradient all had low nitrate values (< 0.01-5.7 mg/L NCb-N), but exhibited a
relatively wide range of 515N values (Figure 7). Considering all of the site wells, there
was no correlation (r2 = -0.0034) between ground water nitrate and chloride values, but
this was predominantly affected by an extremely high chloride result for the ground water
sample from well AR32-3 (Table 17). This was a very shallow well, and this ground
water sample also had the highest levels of ammonium, orthophosphate, sulfate, and TOC
compared to those of all of the other wells (Table 17-18). Excluding this well, there was
r\
a weak positive correlation (r = 0.2351) between ground water nitrate and chloride
values. These ground water samples generally had moderate to high DO levels and very
low TOC concentrations (Table 17) which would not be expected to support significant
denitrification, and the concentrations of nitrate and nitrous oxide were also generally
quite low (Table 18). There was no clear evidence of denitrification provided by the
9
stable nitrate isotope relationships (Figure 8). There was no correlation (r = 0.0000)
between increasing 515N values and decreasing nitrate concentration which would

indicate denitrification (Figure 8a). It is possible that denitrification is occurring, but the
nitrate sources are so varied that this relationship is masked. There was a moderate
positive correlation (r2 = 0.3241) between increasing 518O-NO3 values and 515N-NC>3
values in these ground water samples that would tend to indicate denitrification (Figure
8b), but the data are too variable to draw any substantive conclusions. Interestingly, the
ground water 518O-NC>3 values are all very high at this site, and because denitrification
1 R
would be expected to enrich 5 O-NOs values, this might provide some additional
indication of denitrification. Somewhat surprisingly, all of the wells at this site seemed to
have similar recharge histories, as shown by water stable isotope data grouping fairly
1 R
well around the MWL, with little relative variation in 5 O-H^O values (Figure 8c).
Unfortunately, there were no suitable wells upgradient of the land application areas, and
so it is difficult to conclusively link the high nitrate values with land application of dairy
waste and not fertilizer. However, given the amounts of effluent that were applied, the
sandy nature of the soil, and the high 515N values within and immediately adjacent to the
land application areas, the evidence points to the dairy lagoon effluent as the source of
high nitrate in the ground water at this site.
Evaluation of Additional Stressor Impact. As with the previous site that focused on land
application, there was little consistent evidence showing that the additional stressors
monitored in this study were also being transported past the active soil zone along with
nitrate, although there were isolated occurrences that appeared to be linked to land
application of dairy wastes. Ground water orthophosphate concentrations, with two
exceptions, were generally low (0.025 - 0.060 mg/L PO4-P), and were not correlated with
r\
nitrate concentrations (r = -0.0377). Ground water samples from wells AR31-1 and
AR32-3, however, showed elevated levels of 0.265 and 0.756 mg/L PO/i-P, respectively
(Table 17). As discussed previously, the ground water sample from well AR32-3 had
very unusual chemistry, and the high level of orthophosphate may not be derived from
land application of dairy waste. Conversely, well AR31-1 is located adjacent to a center
pivot (Figure 7) and the ground water sample from this well had a nitrate concentration of
14.6 mg/L NOs-N with a relatively strong animal waste signature of+18.4%o 515N-NO3
(TablelS), and so land application of dairy waste could be the source of orthophosphate

a Values reported as "<" are below detection limits
in this sample. Interestingly, the ground water sample from this well also showed the
highest levels of nitrite and nitrous oxide detected in any of these samples, indicating that
denitrification either had occurred or was occurring in the ground water at this location.
Microbial indicators were sporadically detected in moderate to high numbers in both non-
impacted and impacted ground water samples (Table 19), and there was no correlation
r\
between nitrate and total coliform numbers (r = -0.0787). For example, total coliform
numbers were > 2,420 cells/100 mL in both the non-impacted well AR32-2 (0.92 mg/L
NOs-N) and the impacted well ARWOW (15.6 mg/L NCb-N). The greatest numbers of
all three microbial indicators were found in the ground water sample from well ARWOW,
which had a poor seal (i.e., a barrel over the top) and coincidentally also contained a
floating dead rat. For this particular well, these numbers can be readily attributed to an
artifact of well integrity rather than a significant ground water contamination event.
Arsenic, copper, nickel, and zinc levels were all relatively low in the dairy lagoons and
were near or below detection limits in the ground water samples (Table 19). Selenium
concentrations were moderate in the dairy lagoons (62-109 |ig/L) and appeared to be
uniformly distributed in ground water samples (21-79 |ig/L), although there was a weak
positive correlation (r2 = 0.2943) between ground water nitrate and selenium levels.

0 Values reported as "<" are below reporting limits
Antibiotics, primarily tetracyclines and sulfonamides, were detected in the dairy lagoons,
but at levels much less than those observed in swine lagoons (Table 20). Of these, the
only antibiotic found in ground water was sulfamethazine, and this was detected in only
one sample at a low level (11 ng/L) that was only about twice that of the reporting limit
(Table 20). Still, this detection is plausible, since this ground water sample had very high
levels of nitrate (Table 18) and in a separate study sulfamethazine was also detected in
ground water downgradient from dairy lagoons (Watanabe et al., 2010). Estrogen
hormones were found at relatively low concentrations in these dairy lagoons, and were
rarely detected in ground water (Table 21). Estrone was detected at very low levels (1.0-
1.4 ng/L) in AR8-1 and ARWOW, and each of these wells was located within or adjacent
to a center pivot and both were impacted by nitrate (15.6-56.7 mg/L NOs-N), although
the ground water sample from well AR8-1 did not show an animal waste signature
(Figure 7). These wells were again sampled in 2011, and no estrogens were detected (<
0.3 ng/L). Collectively, these data show that even though ground water contamination by
nitrate occurred due to land application of dairy lagoon effluent at this site, there were
few additional stressors associated with the CAFO dairy waste that could consistently be
found at high levels along with the correspondingly elevated levels of nitrate.

3.5 CAFO Site 5 - Swine Combined (Closed)
Case Study Summary. This is the only site that we have studied to date where ground
water has been significantly and consistently impacted by contaminants other than
nutrients from a CAFO, and in this case represents a very problematic scenario where
swine waste from a leaking lagoon has directly contaminated shallow ground water with
high levels of ammonium (up to 390 mg/L NH4-N), nitrate (up to 78 mg/L NOs-N),
orthophosphate (up to 61 mg/L PO4-P), estrogen hormones (up to 23,800 ng/L estrone),
and arsenic (up to 540 |ig/L arsenic). We have been monitoring remediation efforts for
nutrients at this site for the past nine years, and those results will be published separately.
Analytical data for sampling events in 2003, 2005, 2007, 2009, and 201 1 are presented in
Appendix A.
Site Description. CAFO Site 5 was a farrow-to-wean combined swine facility that has
since been closed. Operations began in November 1992 with four sets of barns and a
central lagoon. There were two sow/boar units and two nursery units, with a combined

total of 7,200 feeder pigs, 2,400 sows, and 120 boars. Wastes from the units were
pumped into a large lagoon which reportedly had a compacted soil liner and were land
applied at various locations around the facility (Figure 9). There are conflicting reports
as to the integrity of this liner, but regardless substantial leakage did occur, and in fact so
much so that reportedly little land application of the effluent was observed during site
operation. Ground water contamination ensued with high levels of ammonium in ground
water adjacent to the lagoon and high concentrations of nitrate in ground water further
away from the lagoon (unpublished data). The impacted aquifer is a shallow
conglomerate of fractured sandstone with interspersed clay and sand lenses, and is
underlain by a thick layer of shale approximately 25-50 ft below ground surface. The
facility was closed and the animals removed in November 1999, in part because of the
ground water contamination issue and in part due to an outbreak of disease among the
64
-------
animals. The lagoon was emptied and the contents were land-applied north of the facility.
A remediation action plan was put into place in 2002-2003, and consisted of an
interceptor trench for ammonium and a haystraw permeable reactive barrier (PRB) for
nitrate. Ammonium was captured using five pumping wells within the gravel-filled
interceptor trench to pump ground water contaminated with ammonium to a large
evaporation basin (Figure 9), and these pumping wells were started in January 2003 at a
combined rate of 7-8 GPM. An additional pumping well was constructed in April 2006
between wells CP2 and CP4 and was operated at 2 GPM to try to reduce high ammonium
concentrations at that location. The nitrate PRB was designed to promote in situ
denitrification for removal of nitrate and was constructed in January 2003, just four
months prior to our first sample event. We have been monitoring this site annually to not
only assess long-term performance of the PRB, but also to evaluate ground water quality
trends across the site.
General Chemistry and Stable Isotope Interpretation. No original swine lagoon matrix
was available for sampling at the start of this study, and so the concentrations of stressors
in the source material are unknown. However, these are expected to be similar to the
types and concentrations of stressors found in other swine lagoons. In contrast to what
was found with the other site operations, ammonium concentrations were quite high in
several of these ground water samples, with five wells ranging from 74-361 mg/L NH4-N
in 2003, 80-354 mg/L NH4-N in 2005, 44-161 mg/L NH4-N in 2007, 22-74 mg/L NH4-N
in 2009, and 25-137 mg/L NH4-N in 2011. Full data sets for these sample events are
provided in Appendix A, and Tables 22-23 provide example data from the 2009 sampling
event for general chemistry parameters, reactive nitrogen, and stable isotopes. With the
exception of well CP18 and several wells affected by the denitrifying PRB, all wells
showing detectable levels of ammonium had animal waste signatures as evidenced by
515N-NH4 values exceeding +10%o (Figure 9, Table 23). One reason why the 515N-NH4
values may have been less in ground water samples taken within and downgradient off
the denitrifying PRB is that the ammonium in these samples was not derived from animal
wastes, but from ammonification of organic nitrogen within the reactive straw matrix.
With few exceptions, nitrate in ground water samples downgradient of the lagoon also

showed an animal waste signature (> +10%o 515N-NC>3), although this also occurred in
some of the ground water samples taken upgradient of the lagoon (eg, wells CP21 and
CP22, Figure 9). In some cases the observed 515N-NC>3 values were surely enriched due
to denitrification (especially within and downgradient of the denitrifying PRB), but
overall the data were too variable to discern general trends of denitrification across the
site. This may be because the 2009 sample data reflect site conditions after several years
of operation of the denitrifying PRB, and it is no longer as active as it had been in the
past. Parts of the PRB in the southwest section are becoming depleted in organic carbon,

a Lagoon was emptied in 1999; matrix is primarily runoff and rainfall
b Values reported as "<" are below detection limits
which is why ground water samples from well CP17 show moderate DO, moderate
nitrate levels, and low TOC values, whereas ground water samples from wells CP34 and
CP35 show low DO, low nitrate levels, and high TOC values (Tables 22-23). Regardless,
concentrations of nitrite and nitrous oxide were low in almost all of the ground water
samples, including those taken from locations which were within or downgradient of the
denitrifying PRB (Table 23). This observation illustrates that the absence of detection of
these transient intermediates of denitrification does not necessarily mean that this process
is not occurring. However, there was also little supporting evidence for denitrification
provided by stable isotope relationships (Figure 10). There was no correlation of

lOa), or of increasing 5 O-NOs values with increasing 5 N-NOs values (r = 0.0127,
Figure lOb), both of which would indicate denitrification. The 518O-NO3 values were
also very high in ground water at this site, similar to what was observed for Site #4, and
the reason for this is again unclear. But regardless of whether denitrification is enriching
515N-NC>3 values, the linkage between the lagoon CAFO wastes as the original source
and the increased reactive nitrogen concentrations downgradient of the lagoon is
unmistakable. Additional evidence for the direct hydraulic connection between the
leaking lagoon and the shallow aquifer is provided by water stable isotope data, which
show ground water in wells immediately downgradient of the lagoon (CP2, CP3, CP4,
CP9, and CP13A) have water stable isotope ratios closer to that of the surface water
lagoon compared to that of the other wells (Figure lOc). Interestingly, water stable
isotope ratios also provide some insights into the nature of the surface water streams in
this area. For example, the surface water sample AC1 shows contamination by
ammonium (3.50 mg/L NFLj-N) and it also contains nitrate (2.55 mg/L NCb-N), both of
which have an animal waste signature as shown by 515N values in excess of+10%o (Table
23). Although this stream sample does show somewhat of an evaporative signature, its
water stable isotope ratio is more closely associated with the impacted ground water
wells than with the other surface water bodies (Figure lOc), which indicates that ground
water is probably discharging into this stream. This is much more apparent for the stream
location NCI (Figure lOc), which has been observed to emanate directly from ground
water discharge during dry weather periods.
Evaluation of Additional Stressor Impact. In contrast to the other sites in this study, very
high levels of orthophosphate (3.26-21.3 mg/L PO/j-P) were found in ground water
samples from several wells (wells CP2, CP3, CP4, and CP13A) immediately adjacent to
the leaking lagoon, and ground water samples from these wells also showed very high
ammonium levels which were strongly correlated (r2 = 0.9406) with orthophosphate
levels (Tables 22-23). Ground water orthophosphate concentrations ranged from 0.031-
0.285 mg/L PO/i-P for the other wells sampled in 2009, and did not correlate with either
nitrate (r2 = 0.0128) or ammonium (r2 = -0.0028). Microbial indicator counts were

a Lagoon was emptied in 1999; matrix is primarily runoff and rainfall
b Values reported as "<" are below detection limits
generally low to moderate throughout the study (Appendix A), although there were
sporadic high counts in certain wells now and again, as illustrated for the 2009 data in
Table 24. Fecal enterococci counts were initially very high (> 2,420 cells/100 mL) in the
PRB wells NB1-NB5, presumably due to animal manure that may have been present in
the square and round bales used for the PRB, but these values dropped rapidly with time
(Appendix A). However, this does indicate that caution should be used in evaluating
additional stressors in ground water downgradient of the PRB, since the source of these
may not be the original swine CAFO waste. It does seems likely that arsenic, and to a
70
-------
lesser extent selenium, was present at moderate to high concentrations in the original
swine waste, because ground water concentrations of these two metalloids in 2009 were
elevated in the downgradient wells immediately adjacent to the lagoon (Table 24), and
these concentrations were even higher in 2003 (Appendix A). Both of these compounds
are listed as feed additives for swine (Luce and Maxwell, 1991), and could be expected to
be in the original swine waste. For the 2009 sample analyses, elevated arsenic
concentrations as measured by ICP-OES were confirmed by ICP-MS (Table 24).
Although swine waste is the most likely source of the elevated arsenic and selenium
levels observed in these impacted wells, it is also possible that infiltration of liquid swine
waste also affected oxidation-reduction potential and helped mobilize naturally-occurring
arsenic and selenium from the subsurface matrix. Surprisingly, there was little evidence
of veterinary antibiotics in any of the ground water samples from either the 2003 or 2009
sampling events (Table 25). Sulfamethoxazole was detected in 2003 in one upgradient
well (Table 25), but at a level (80 ng/L) close to the reporting limit (50 ng/L), and this
finding is somewhat questionable because Sulfamethoxazole is not generally used in
swine CAFOs (Pruden, 2009b). Lincomycin was detected in 2009 in two impacted wells,
although in one case the value (6 ng/L) was close to the detection limit (5 ng/L) here as
well. Based on information from site personnel, antibiotics were routinely used in this
swine CAFO, but specifics regarding identity and concentration were not available.
Conversely, estrogen hormones were routinely detected in the most impacted wells
throughout this study, and often at concentrations well above the quantitation limits
(Table 26). For the 2009 data, there is a moderate positive correlation between ground
water ammonium concentrations and total estrogen levels (r2 = 0.4563), and an even
better correlation between ground water ammonium concentrations and logarithmic
r\
values of total estrogen levels (r = 0.8433). Unlike as has been observed elsewhere
(Kolodziej and Sedlak, 2007), these ground water estrogens have been consistently
detected and concentrations are generally decreasing with time (Figure 11). Well CP7 is
an exception, but this may be because it is further away from the source and is more
subject to variations in ground water flow. Ground water flow fluctuates at this site in
response to rainfall events, and water table elevations have changed by as much as five
feet over the course of this study. In addition, the pumping wells for the ammonium

interceptor trench were shut down for about a year starting in mid-July 2007. Although
estrogen levels are dropping, it may be several years before l?p-estradiol and estrone
drop below the PNECs of 1.0 ng/L and 3-5 ng/L, respectively, as established by Young et
al. (2004). In summary, there is good evidence that this swine operation resulted in
contamination of ground water by not only nitrate and ammonium, but also by
orthophosphate, arsenic, and estrogen hormones. It should be emphasized that this
occurred primarily through a direct hydraulic connection between the leaking lagoon and

3.6 CAFO Site 6 - Beef Feedlot
Case Study Summary. Nitrate contamination is pervasive in the ground water at this beef
feedlot site, with an average concentration of 64 mg/L NOs-N (29 wells) and a maximum
value of 167 mg/L NCb-N. Nitrate most likely derives from several CAFO waste sources
at this site, including the feedlot, lagoons, land application areas, and underground piping.
However, we found very little evidence of ground water contaminants other than nitrate
(and occasionally ammonium). In a few impacted wells there were slightly elevated

levels of nickel and selenium, but there was no consistent animal waste signature based
on the stable nitrate isotope data for these samples. In ground water samples obtained
from one poorly-sealed well the antibiotic sulfamethazine was detected at very low levels
(14-17 ng/L) in both field duplicates. Estrone was also detected in this same well at very
low levels (1.8-2.3 ng/L) in both field duplicate ground water samples, and a follow-up
sample event two years later again showed that this well contained estrone, this time at
1.1 ng/L in each field duplicate ground water sample.
Site Description. CAFO Field Site 6 is a beef feedlot operation that was started in the
1940's, but at a much smaller scale at that time. Since that time it has expanded to
include about 27,000 cattle. There is an area set aside for composting of manure and
carcasses, and there are unlined lagoons constructed around the pens which function
more like runoff retention ponds rather than anaerobic lagoons (Figure 12). In fact some
of these lagoons are supersaturated in dissolved oxygen (12-22 mg/L O2) due to the
presence of algae. These lagoons (LAG1-3) receive runoff from the pens and are
pumped to a large secondary lagoon (LAG4) located south of the feedlot. LAG4 also
receives ground water as make-up water so that this lagoon effluent can be used for
irrigation. Effluent is also pumped from lagoons LAG2 and LAGS to center pivots and
land applied to irrigate and fertilize grasses and corn crops that are grown for grazing
and/or feed. The topsoil is sandy, with mixed sands and clay lenses in the vadose zone
grading to general sands in the aquifer, underlain by red bedrock at about 65 ft.
General Chemistry and Stable Isotope Interpretation. The exact source of CAFO-derived
nitrate contamination in the ground water is difficult to ascertain at this site, because
there were many possible avenues, including manure/carcass composting, leaking runoff
retention ponds and lagoons, leaking piping infrastructure, infiltration from the feedlot
itself, and over-application of solids as well as lagoon effluent. This may be why there
appeared to be localized trends in the ground water chemistry, but no overall correlation
of chloride, sulfate, TOC, or 515N values with nitrate concentrations (Tables 27-28). For
example, ground water samples from the impacted wells WB11-WB14 had moderate to
high nitrate concentrations (29-148 mg/L NCb-N) and high chloride levels (138-666

had generally lower chloride levels (61-183 mg/L Cl) and no animal waste signature

mg/L Cl), whereas ground water samples from wells WB1 and WB16 also showed very
high sulfate levels (1,140-1,170 mg/L SO4) and very low chloride levels (11-89 mg/L Cl)
compared to those of most of the other wells (Table 27). There was also no correlation
between ground water nitrate and chloride levels (r2 = 0.0259). Of the 28 wells with
ground water nitrate exceeding the MCL of 10 mg/L NOs-N, about 25% had borderline
animal waste signatures (515N = +8%o to +10%o) and about 30% had definitive animal

-------
waste signatures (515N > +10%o). One well (WBW10) represented an anomaly in that the
ground water sample from this well had very low nitrate (0.05 mg/L NOs-N), but had the
highest levels of ammonium (20.3 mg/L NH4-N) and methane (12.2 mg/L) compared to
those of any of the other wells (Tables 27-28). Because this well is not located adjacent
to a lagoon (Figure 12), it is difficult to understand why this ammonium level would be
so high, since these levels are typically seen only in ground water directly impacted by
leaking lagoons. Furthermore, the ground water samples from wells WB11 and WB12,
located between the upgradient lagoon LAG2 and this well, had very low ammonium
levels (< 0.03 mg/L ML;-N). Well WBW10 was a large-diameter well with a loose
fitting steel plate as a cover, and site personnel suspect that an animal might have fallen
into this well in the past. But it is also possible that there could have been leakage
somewhere along the pipeline transferring effluent from lagoons LAG2 and LAG3 to the
land application areas.
The impact of denitrification is also hard to assess at this site. Several ground water
samples had low but definitive levels of nitrite and nitrous oxide (e.g., > 0.10 mg/L as N)
showing that denitrification was occurring (Table 28). However, DO values were
moderate to high and TOC values were less than 5 mg/L in over 80% of the ground water
samples (Table 27), and so it is unlikely that denitrification would have reduced nitrate
concentrations or enriched 515N values to any significant extent. This variability which
potentially arises from multiple source terms also complicates the interpretation of stable
isotope relationships, which seemed to provide little evidence of denitrification (Figure
9 IS
13). There is no correlation (r =-0.0003) between ground water 5 N-NOs values and
nitrate concentrations (Figure 13a), and the positive correlation between ground water
615N-NO3 and 618O-NO3 values (Figure 13b) is very weak (r2 = 0.0541). The observed
variability in the ground water chemistry is exacerbated by the variability in ground water
age among the wells sampled, as shown by the wide range of 518O-FL:O values in these
samples (Figure 13c). Interestingly, well WB20 is more closely grouped with the surface
water lagoons than with any of the other wells and shows a definitive evaporative
signature (Figure 13c). This well has a very shallow screen interval compared to the
other wells (Table 27) and is located adjacent to LAG4 (Figure 12), and its ground water

sample shows a strong impact from animal waste as represented by high concentrations
of ammonium (8.94 mg/L NH4-N), nitrate (40.3 mg/L NO3-N) and TOC (45.7 mg/L), as
well as strong animal signatures from ammonium (+30.8%o 515N-NH4) and nitrate (+39.9%o
515N-NC>3). These observations indicate that this well is probably being directly impacted
by leakage from lagoon LAG4. In summary, regardless of the variability in ground water
chemistry at this site, most of the evidence shows that ground water contamination by
nitrate is derived from CAFO wastes, and that denitrification processes are not likely
enriching 515N values to the extent necessary to lead to misinterpretations of stable
nitrogen isotope data.
Evaluation of Additional Stressor Impact. Ground water orthophosphate concentrations
ranged from 0.038-0.394 mg/L PO4-P in these wells, and again there was no correlation
with nitrate concentrations (r2 = -0.0062). Although there was little evidence of
additional stressors other than nitrate in these impacted wells, what few detections
occurred were generally found in those ground water samples showing an animal waste
signature. Total coliform counts were low (< 20 cells/100 mL) in all ground water
samples except for that taken from well WB20, which yielded 816 cells/100 mL (Table
29). As discussed earlier, this well was most likely directly impacted by leakage from the
adjacent lagoon LAG4. Fecal coliforms were not found in any of the ground water
samples, but fecal enterococci were detected in several ground water samples, with the
highest numbers (91-108 cells/100 mL) found in ground water samples from wells WB11
and WB14 (Table 29). These two wells were located adjacent to the feedlot and lagoons
(Figure 12), and ground water samples from each well showed animal waste signatures
with 615N-NO3 values ranging from +13.5%o to +22.3%o (Table 28). Regarding metals
and metalloids, ground water concentrations of arsenic, copper, and zinc were either
below detection limits or were at very low levels in all of the ground water samples, with
the exceptions of those from well WBW17 and WBW29, which contained 32 |ig/L Cu
and 433 jig/L Zn, respectively (Table 29). These are both water wells with submerged
metal pumps, which may be the cause of these detections. There was some evidence of
elevated nickel and selenium levels in several of the ground water samples, but the
concentrations were still quite low (Table 29). Ground water samples showing the

sources of these stressors. However, elevated concentrations of copper and nickel have
been found underneath unlined cattle slurry lagoons elsewhere (Gooddy et al., 2002).
The lagoons at this beef feedlot site had relatively low concentrations of antibiotics
(Table 30) and estrogen hormones (Table 31) compared to lagoons associated with other
types of CAFOs, and so perhaps it is not surprising that these stressors were generally not
detected in these ground water samples despite the relatively high levels of nitrate. The
one exception was observed for well WBW10, the somewhat anomalous well described
earlier that was poorly-sealed and which was contaminated with ammonium (20.3 mg/L
NH4-N) instead of nitrate. The antibiotic sulfamethazine was detected at very low levels
(14-17 ng/L) in both field duplicate ground water samples from this well (Table 30), and
this antibiotic has been detected in ground water downgradient of beef feedlots elsewhere
(Batt et al., 2006). Estrone was also detected in this both field duplicate ground water
samples from this well, but the concentrations were low (1.8-2.3 ng/L) and close to the
quantitation limit of 1.0 ng/L (Table 31). A follow-up sampling in 2011 confirmed the

detection of estrone in this well, but again at a very low concentration (1.1 ng/L). As
observed earlier, site personnel have speculated that the source of contamination in this
well might have been due to the death of an animal that became trapped within the well,
but it is also possible that leakage from a lagoon or a pipeline carrying lagoon effluent for
land application could also be the cause. In summary, even though ground water
contamination by nitrate is extensive at this site and probably derives from several
avenues of transport of reactive nitrogen from CAFO waste, there was little evidence of
consistent ground water contamination by the other stressors monitored in this study.

3.7 CAFO Site 7 - Swine Farrowing Sow
Case Study Summary. Unlike the other sites previously discussed, this site was chosen to
represent a relatively non-impacted case study. Ground water contamination by nitrate
has not occurred in the off-site wells downgradient from this CAFO, and is not expected
to happen, if at all, for several years due to the extent of the vadose zone and the depth to
ground water. We included this site to document background conditions in the event of
future impacts, and to ascertain whether the CAFO waste stressors monitored in this
study were already present. Surprisingly, moderate levels of fecal enterococci were
detected in these off-site ground water samples, and in one instance estrone was detected
at a very low level (0.5 ng/L). The source of these contaminants is unknown, and could
possibly be due to grazing livestock in this area.
Site Description. CAFO Site 7 is a farrowing sow swine facility that began operation in
May 1999 with about 25,000 swine, including 19,920 gestating sows, 4,980 farrowing
sows, and 100 boars. Prior to 2004, swine waste from two large barn complexes was
treated using a series of five anaerobic lagoons with liquid manure being first directed to
two covered digester lagoons (LIOLD, L2OLD), then to two uncovered primary lagoons
(L3OLD, L4OLD), and finally to an uncovered secondary lagoon (L5OLD) before being
used for land application (Figure 14). All of these lagoons were lined with synthetic
liners. Prior to 2005, the secondary lagoon effluent was pumped to four center pivot
locations northeast of the barns and land applied for production of wheat, corn, and
alfalfa. The subsurface geology at this site is highly heterogeneous and consists of mixed
sands with silt and caliche stringers, and depths to ground water range from 40-130 ft
below ground surface. Regional ground water flow is south towards a small river. There
were concerns regarding ground water impacts to a wildlife management area about one
mile south of the land application area, and five monitoring wells (BV1-BV5) were
constructed in July 1999 on private and public lands south of the facility (Figure 14). We
conducted quarterly sampling of these five off-site monitoring wells for routine chemical
parameters from August 2000 through July 2002, and in late July 2002 were granted
access to the facility to sample the five lagoons as well as on-site monitoring wells

adjacent to those lagoons. Because most of those monitoring wells were dry, we were
only able to get a complete sample out of one well (MW188) and had to sample multiple
times with a dedicated bailer to get a partial sample from another (MW192). This
marked the end of our quarterly sampling program. During this time, additional concerns
had been brought forth later regarding the potential for over-application of CAFO waste
based on the volumes being generated and the amount of land available for irrigation, and
a settlement was reached in December 2001 which led to several operating changes at
this facility. The old lagoons were subsequently decommissioned, and in 2003 a revised
system was brought on-line consisting of two covered settling basins, two mechanical
solids separators, a 4-acre concrete pad for composting solids, a primary anaerobic
lagoon (L1NEW), a secondary storage lagoon (L2NEW), and an evaporation basin
(Figure 14). All of these surface water impoundments were lined with synthetic liners,
and the composted solids were commercially sold or otherwise distributed off-site. The
86
-------
net result has been a large reduction in the amount of liquid manure that needs to be land-
applied. Additional land area was also subsequently obtained for land application,
including a new center pivot area located just west of the new lagoons (Figure 14), and
land application began on this area in May 2005. We revisited this facility in September
2010 to sample the new lagoons and to ascertain whether there had been any significant
changes in ground water chemistry in the off-site wells during the past eight years.
General Chemistry and Stable Isotope Interpretation. These wells are screened at much
deeper intervals those at the sites previously discussed, and the depth to ground water
ranges widely (Table 32). Ground water nitrate levels were low (1.48-3.12 mg/L NOs-N)
in these off-site wells in 2002, and there was no evidence of an animal waste signature by
515N (< +5%o), nor was there any significant increase in ground water nitrate levels even
after eight years (Table 33). Ground water samples from the two lagoon wells sampled in
2002 showed contamination by reactive nitrogen, but the sources are uncertain. Ground

a One of two sampling locations in this lagoon
b Values reported as "<" are below detection limits
water from well MW188 had a high level of ammonium (13.3 mg/L NH/t-N) and a low
level of nitrate (5.20 mg/L NOs-N), whereas ground water from well 192 showed only a
high level of nitrate (56.7 mg/L NOs-N). In both cases there was no animal waste
signature by 515N-NC>3, and unfortunately the ammonium found in MW188 was not
characterized for 515N-NH4. Ground water DO levels are moderate and TOC levels were
very low at this site (Table 32), and ground water nitrite and nitrous oxide concentrations
were also very low (Table 33). It seems therefore unlikely that denitrification was
occurring to any significant extent, and the nitrate stable isotope relationships do not
provide any evidence to show otherwise (Figure 15). There was no correlation (r2 = -
0.0394) between increasing ground water 515N-NC>3 values and decreasing ground water
nitrate concentrations that would indicate denitrification (Figure 15a), although there was
a positive correlation (r2 = 0.5832) between ground water 515N-NC>3 and 518O-NO3 values
that could support this (Figure 15b). However, if denitrification were responsible for this
positive correlation, the slope of the line would theoretically be between one and two
(Kendall et al., 2008), and the slope of this trend line is around eight. Regardless, the

data are too few to attach much significance to the interpretation of these stable nitrate
isotope relationships. In contrast, stable water isotope ratios were consistent with
expectations regarding the surface water samples, with the covered digesters and the
secondary lagoons showing the least and greatest evaporative signatures, respectively
(Figure 15c). In addition, the stable water isotope ratios for the covered digesters were
above the MWL, as would be expected due to the enrichment of deuterium by
methanogenesis (Hackley et al., 1996), and methane concentrations were much higher in
these covered digesters compared to the other lagoons (Table 32). Ground waters from
1 &
these deeper wells were less enriched in 5 O-H^O than the shallower ground waters
1 &
associated with the other sites, and in this case the 5 O-H^O values were especially low
in ground water samples from well BV4 from both sample events (Figure 15c).
Evaluation of Additional Stressor Impact. Nitrate concentrations were low in ground
water samples from these off-site wells and few additional stressors were expected to be
present. Orthophosphate concentrations in ground water were moderately low and
ranged from 0.030 to 0.111 mg/L PO/t-P (Table 32). Surprisingly, moderate levels of
fecal enterococci were detected in ground water samples from these off-site wells (Table
34). The source(s) of these are unknown, although there is grazing livestock in this area.
The moderately high level of fecal enterococci observed in the ground water sample from
well BV4 in 2002 was not related to land application of CAFO waste, because the center
pivot in the land application area just north and upgradient of this well (Figure 14) was
not yet in operation. The highest level of fecal enterococci was found in ground water
from the CAFO lagoon well MW188, which also had a relatively high ammonium level
(Table 33), and again may indicate some contamination of ground water from the very
high levels of fecal enterococci found in lagoon L5OLD (Table 34). In contrast, metal
and metalloid concentrations were either very low or were not detected in these well
samples. Ground water arsenic concentrations, as confirmed by ICP-MS, ranged from
5.1-21.4 |ig/L in these off-site wells, with As (V) being the predominant species in all
wells (Appendix A). The two new lagoons had arsenic concentrations ranging from 95-
106 |ig/L As (as measured by ICP-OES), and arsenic was again mostly present as As (V),
although in this case there was also some evidence of Roxarsone in L2NEW, albeit at

very low levels (Appendix A). As noted earlier, Roxarsone is occasionally used in swine
operations, and has been detected in swine lagoons (Makris et al., 2008). Ground water
samples from well BV1 also had very low but detectable concentrations of zinc (61-90
Hg/L Zn) in both 2002 and 2010 (Table 34). Although this well is immediately
downgradient of L5OLD, there are no additional indicators of impact from CAFO waste
based on general chemistry parameters (Table 32) or stable isotopes (Table 33), and
ground water chloride concentrations have remained low (40-50 mg/L) throughout the
2000-2002 sampling period (unpublished data). A few veterinary antibiotics were
detected in the two new swine lagoons at this site (Table 35), but the numbers and
concentrations were generally less than those observed for other swine lagoons.
Veterinary antibiotics were not detected in ground water samples collected from the off-
site monitoring wells. As expected, estrogen concentrations were quite high in these
swine lagoons, but only estrone was detected in one well, and at a very low level of 0.5
ng/L (Table 36). Interestingly, this again was well BV1, which compared to the other

off-site wells had the slightly higher levels of arsenic and zinc reported earlier. The
analytical data and quality control measures were especially good in this case and support
this as a true detection in this ground water sample, but the concentration was still less
than 1 ng/L and was also very close to the quantitation limit (0.3 ng/L). Considering the
data obtained to date, and with the exception of fecal enterococci, these off-site wells
show little impact by nitrate or any other stressors related to CAFO waste. These data
will provide background information to assess any future impacts from this facility,
especially in the location of BV4 where land application of swine waste commenced in
2005 just upgradient of this well and affords the greatest potential for ground water
contamination by nitrate and perhaps other CAFO stressors.
4.0 Summary and Recommendations
Collectively, these data show that ground water contamination by nitrate or ammonium
can occur at very different types of C AFOs, whether through leaking lagoons, leaking
pipes or infrastructure, land application of wastes in excess of agronomic needs, or other
factors. Because of limited site access and resource constraints, it was beyond the scope
of this study to evaluate the relative contributions of the individual sources leading to
ground water contamination by nutrients at each of these study sites, or to ascertain
whether adequate management strategies were either in place or being rigorously
followed. But in some cases it is clear that leaking lagoons (Sites #2 and #5) and
excessive land application (Sites #3 and #4) were the sources for the high ground water
nitrate or ammonium levels observed in the sampled wells, and actions have been taken
to mitigate or eliminate these source terms at these sites.
Generally, ammonium was observed in ground water only at those sites where there
appeared to be a direct hydrologic connection between the sampled wells and leaking
lagoons (Sites #2 and #5). These two sites have since been closed and the lagoons have
been decommissioned. The lagoons at these two sites were not constructed with
synthetic liners, nor was there any evidence that clay or other fill material had been
93
-------
brought in to construct liners. Although NPDES regulations do not specifically require
the use of liners at CAFO lagoons, permitting authorities have the discretion to include
additional special conditions such as liners where there is a potential to discharge to
ground water that has a direct hydrological connection to waters of the U.S. (USEPA,
2012d). It has been estimated that in this region, which includes the study area, roughly
80% of the CAFO lagoons rely on in situ clay for bases or have clay liners, and about 15%
(mostly swine lagoons) use synthetic liners. The remaining 5%, including the two study
sites listed above, are either unlined or have no available construction information.
Leaking lagoons would be expected to have a more direct impact on ground water quality
than land application of CAFO wastes, especially in situations where there are elevated
water tables and leakage occurs throughout the lagoon bottom or sidewalls. In reality, all
CAFO lagoons do in fact leak, at least to some extent, but with properly-constructed
lagoons the leakage rates are supposed to be low enough to preclude adverse
environmental impacts. More information is needed on whether design leakage rates are
acceptable in relation to diverse hydrogeological settings, and whether additional
guidance is needed for lagoon construction. Land application, on the other hand, uses a
very active surface soil matrix and leads to more extensive removal of contaminants from
water infiltrating through the soil profile due to enhanced volatilization, photolysis, and
aerobic biodegradation. Even so, land application can lead to a larger areal extent of
ground water contamination, especially in locations with multiple center pivot sprinklers
(e.g., Site #4).
We found little evidence of significant ground water contamination by stressors other
than nitrate or ammonium at these sites, except in those cases where CAFO wastes leaked
directly from the lagoons into associated aquifers. Even in those cases, where ground
water nitrate concentrations greatly exceeded the MCLs and even moderate to high levels
of ammonium could also be detected, the other stressor concentrations were generally
quite low. This suggests, but does not necessarily imply, that if CAFOs were properly
managed so as to preclude ground water contamination by nitrate in excess of the MCL,
then the other stressors associated with CAFO wastes in this study (microbial indicators,
94
-------
metals and metalloids, antibiotics, and estrogen hormones) might also be attenuated to
acceptable risk levels. Additional field studies are needed to test this hypothesis,
preferably with more frequent sampling events to account for seasonal variations and
long-term effects. For most of the sites in this study (Sites #1, #2, #4, and #6), the
sampling frequency was very limited (one to three sample events over several years), and
it is possible that there could have been pulse events of ground water contamination by
these other stressors caused by seasonal variations or intermittent discharges that could
have been missed. But this possibility is very site-specific and would not be expected to
be an issue where routine land application or leakage from faulty lagoons generates
relatively continuous sources.
It is also important to note that this study did not evaluate true pathogens, other synthetic
hormones (e.g., trenbolone), or other antibiotics (e.g., monensin), and additional research
is also needed to ascertain whether these stressors would exhibit similar potential for
contaminating ground water through leaking lagoons or land application of CAFO wastes.
This study also does not address estrogen conjugates, which are expected to be more
mobile in the soil than free estrogens, nor does it address long-term effects from the
buildup of salts, metals, phosphate, and micronutrients on ground water quality or soil
productivity. Finally, the relatively few detections of other stressors in nutrient-impacted
ground waters in this study should not obscure the fact that contamination of ground
water by nitrate or ammonium is in itself a significant environmental problem, and can
lead to legacy impacts on receiving surface waters with direct hydrologic connection to
contaminated ground waters.
These are all commercial operations and in many respects are very typical of the types of
commercial CAFOs found in the south central United States. But it should be understood
that these sites were chosen for this study based on the fact that, with one exception, the
operation had already resulted in ground water contamination by nitrate and/or
ammonium. We specifically selected these sites for this study because we wanted to
determine whether other stressors found in CAFO wastes were also present in the
contaminated ground water. In this respect, then, these sites do represent more
95
-------
problematic scenarios, and therefore this suite of case studies does not imply that six of
seven CAFOs in the U.S. will have contaminated ground water. However, the design and
nutrient management failures responsible for ground water contamination at these sites
can and probably do occur at CAFO sites across the U.S., although the extent has not
been determined and should be investigated. Finally, much more work is needed to
address the efficacy of currently accepted CAFO nutrient management strategies (i.e.,
BMPs) for ground water protection from contamination by nutrients as well as other
stressors, and to ascertain whether additional guidance or regulatory controls are needed.
5.0 Quality Assurance
This project was designed to evaluate CAFO impacts on ground water quality through
examination of several commercial field operations as case studies. A Quality Assurance
Project Plan (QAPP #G-10033) was followed throughout this study. Field data were
obtained as described in this report and met the project's data quality requirements. The
only exception to this occurred in the analysis for estrogen hormones by GC/MS/MS
during 2009, where problems were encountered during switchover to a new instrument
that led to false detections at or near the quantitation limit. For this reason, it was
decided to not provide estimates of concentrations of estrogen hormones in samples
analyzed in 2009 at values less than the quantitation limit. For consistency, this was done
with the estrogen hormone data for the other years as well. This approach was deemed
reasonable because these limits are in the very low nanogram per liter range, where the
potential for data artifacts caused by matrix interferences becomes much greater. It
should be noted that the analysis for antibiotics by LC/MS/MS is subject to similar
constraints, which is why the outside laboratory used for antibiotic analyses also does not
provide concentration estimates less than the quantitation (reporting) limit. Conclusions
and recommendations made in this report are supported by these data, and are
scientifically, but not legally defensible. Caution is warranted when extrapolating this
information and findings to other CAFO sites.

Task: 5823
Sample Site: [CAFO Site #2] Shaw Sample Set No.: 5956
Date Collected: Feb. 22, 2011 Sample Matrix: Groundwater/blanks
Date Received: Feb. 22, 2011 Analysis Type: GC/MS/MS
Date Extracted: Feb. 23, 2011 Sample Preparation: HLB Extr, Deriv
Date Analyzed: April 12 - 14, 2011 Total Extr. : 7
No. Samples Analyzed: 9
Method Used: "RSKSOP-253/1 "Quantitation of estrogens in ground water and
animal waste lagoon water using solid phase extraction, pentafluorobenzyl and
trimethylsilyl derivatization and gas chromatography electron capture negative
ionization /mass spectrometry/mass spectrometry."
As requested in technical directive, 7MD132ED, nine groundwater and blank water
samples from the [CAFO Site #2] site were extracted and analyzed for the
estrogens: estrone (E1), 17-oc-estradiol (ocE2), 17-(3-estradiol ((3E2), 17-oc-
ethynylestradiol (EE2) and estriol (E3) using RSKSOP-253/1 by GC/MS/MS. The
results, QC tables, sample processing timelines, data charts, and processing
queues are provided in a separate Excel file.
The GC/MS/MS analysis of the extracts prepared for this TD was delayed 47 days
due to software problems and the failure of a power supply in the instrument
computer. Before the analysis was started, maintenance was done on the GC and
B-l
-------
MS ion source. In the GC, the injection port liner (Uniliner), the first analytical
capillary column and the GC-MS transfer capillary were replaced. In the MS, the
lenses, ion volume and QO were cleaned. The filament was examined and was
determined to be in good condition. The MS was tuned and calibrated and the MS
response for the calibration gas was found to be within specifications. The
archived estrogen standard was analyzed and the response was deemed to be
sufficient although it was somewhat lower than found previously. The archived
extracts for this TD were analyzed as per RSKSOP 253. The calibration curves for
the estrogens were excellent with all the R2 values being greater than 0.998. This
along with the successful accomplishment of the measurement quality objectives
(MQOs) provides evidence that archiving the standards and sample extracts for 47
days did not have a detrimental effect on the quality of the analysis. The extracts
were stored in un-pierced GC sample vials at 4°C.
During the extract analysis, the surrogate peak area was monitored to see if the
autosampler was functioning as expected. Seven of the extracts required
reinjection because of low surrogate peak area. Before the analysis of the next
sample set, the injector syringe will be replaced.
Quantitation. Quantitation of the estrogens was done using all of the MS/MS ion
pairs. Estrone was found in three samples: GR2-2, GR2-2, and GR3 at 0.21, 0.23
and 2.65 ng/L, respectively.
QA Objectives. All QA data quality objectives were met for blanks, duplicates, %
recovery of standards, second source standards, and spike recoveries in fortified
blanks and spiked samples.
Peak Area of IDS and Surrogates. The Excel spreadsheet "Peak area IDS surr"
provides plots of the peak areas of the surrogate and IDS compounds in each of
the standards, blanks and extracted samples. The plots show that a matrix effect
was present in the extracted samples: GR2-1, GR2-2, and GR3. Here the
response for the IDS and surrogates are lower than that found in the other
standards and extracts. The peak area of the surrogate, 7ME2 follows almost
exactly the changes in peak area of the IDS compounds. This suggests that the
variability of the peak response of the surrogate and IDS compounds between
samples may be due to a matrix effect that causes decreased response in the IDS
and surrogate compounds. There is good peak area agreement for duplicate
injections of the extract of GR2-1.
Retention Time Ratios. Plots of the relative retention time (RRT) ratios for
estrone, oc-estradiol, (3-estradiol, ethynylestradiol, and estriol are provided in the
Excel spreadsheet "Relative Retention Time." Circled data points correspond to
relative retention time ratios found for standards. For the estrone, there are
numerous RRTs for the extracted samples that are below the lower 3o limit.
B-2
-------
Relative Intensities of MS/MS Transitions. MS/MS transition profiles are
provided for estrone, oc-estradiol, (3-estradiol, ethynylestradiol, and estriol. There
are good-to-fair index matches for estrone in three samples: GR1 -2, GR2-2 and
GR3. The index matches for these extracts are greater than 750. Peak areas
were found in almost all of the estrone extracts although the index matches were
all less than 500. The intensities of the target estrogens in these samples are all
very weak. This supports a data label of "Not Confirmed."
Estrone. There is strong evidence that estrone is present in three samples:
GR1-2, GR2-2, and GR3. Peak areas were found in other sample extracts but
RRT mismatches and poor MS/MS index matches require a data label of "Not
Confirmed."
17oc-Estradiol. No evidence of oc-estradiol was found in the groundwater samples.
17|3-Estradiol. There was slight evidence of (3-estradiol peaks in some of the
sample extracts but the MS/MS index matches for these peaks were below 700.
17oc-Ethynylestradiol. No peaks corresponding to EE2 were found in the
groundwater samples or blanks.
Estriol. No peaks corresponding to E3 were found in the groundwater samples or
blanks.

Comments:
1. This section provides QC for the derivatized standards which are not extracted. The concentration (pg/uL) is provided as the extract concentration.
3. The measurement quality objective (MQO) for the cleanliness of the laboratory derivatization blanks (without IDS) is that no compounds be detected with a peak area that is greater than 50% of the peak area in the lowest calibration standard
(QL). The % of peak area in the QL is determined by dividing the peak area found in the blank by the peak area in the lowest calibration standard. This MQO was met for all the derivatization method blanks.
4. The measurement quality objective (MQO) for the cleanliness of the laboratory IDS derivatization blanks is that no compound be detected at a concentration that is greater than 50% of the concentration of the compound found in the lowest
derivatization method blanks.
3. The MQO for the accuracy of the continuing calibration check standards (CCC), second source standards (SS) and laboratory control spikes (LCS) is 80 -120% recovery. This MQO was met for all QA check standards.
Notes:
1. The spreadsheet "Data Result Labels" provides definitions for abreviations found in the data report.
2. MB - indicates method blank (derivatization blank). CCC indicates continuining calibration standards. SS indicates second source standard. % REC - Percent Recovery which is calculated as the percentage of the results to the true values.
It equals to % accuracy for CCC. NF denotes that no response was found for the parameter at all.

A number in a data cell (x.xx) indicates that the compound was identified at the concentration
provided. This means that the identified estrogen eluted at the correct retention time in the
chromatogram, the relative intensities of the MS/MS ion pairs for the peak matched that of the
standards, and the concentration of the target estrogen was above the quantitation limit. Other data
labels that can occur in the report are:
BQL This indicates that a peak of weak intensity was found at a concentration above the method
detection limit (MDL) but below the quantitation limit (QL). The identified estrogen eluted at the correct
retention time in the chromatogram and the relative intensities of the MS/MS ion pairs of the sample
matched that of the standards. The index match was greater than 700 - 750. Because the reported
concentration is below the lowest calibration standard, the concentration should be considered an
estimate.
