interview with
Bruce Ross
Auburn Wastewater Treatment Plant
...
Me: What kind of pre-testing do you do on the fluid you receive?
Bruce: What we do is, as part of our industrial pre-treatment program, were required to
characterize the waste prior to accepting it. However, in this case, we have been accepting
for years simply as brine. And uh, really much to the surprise to us who are involved in the
engineering department, and who handle, uh, I handle the industrial pre-treatment program, so
what we had to basically do was back out, or back into that procedure. We received lab results
from each of the well developers that were developing, or discharging to the plant at the time.
This was back in 2008. And this came to us from a call from DEC, inquiring as to whether or
not we were taking this fluid. Well, actually, we didnt think we were taking any of that, and,
personally, I had no knowledge of it. So, when I asked the people at the plant, they said, Well,
we take brine, but they didnt know any difference and neither did anybody else at that time.
So, what we did is we had each of the developers, the well developers, at that time send us
lab results for what they had. And, uh, we basically did some calculations, we compared those
results to our headworks (?) analysis, that was revised in 2000, and at that point consideredwhat we had taken and what we had experienced at the plant, which was really nothing.
However, there are two considerations at the plant that you have to think about, and one is
passthrough, and another is interference.
And so, up to that point no one at the plant had experienced any interference, and had they
experienced interference they probably would have said, Hey, were taking something thats not
right. And none of our discharge monitoring reports ever indicated a problem. So, thats pretty
much it in a nutshell, but when we looked like things like chloride and dissolved solids that are in
this material, as well as BTEX p-tex, oil and grease (?), and iron, any kind of metals, that might
be in it and found that our plant removes anything that is high enough in concentration to be
concerned about. And again, the results of our monthly discharges were clean. And when Im
thinking of that Im referring to iron, because iron tends to be periodically in this water, uh, quite
high. So that being the case, the DEC told us Well, we will allow you to continue to take what
water you have taken, but no more. And so, at that time, we were probably taking anywhere
from, uh I dont know, it might have been 100-200 thousand gallons a day. After that, as things
became a little more public on the matter, I think some of the well developers began to back
on their production. And so we began to get less water. What DEC required of us was that we
Exhibit D
-
8/3/2019 Onondaga Nation Comments on the 2011 Hydrofracking SGEIS
35/80
permit each of the developers under the pre-treatment program, and thats all thats been done.
And so right now Im waiting for the sampling results from them.
So what we did was we permitted them, theres probably 6 or 8 that are permitted, and I think
weve only had one that has discharged this year, this first quarter, in February. Other than
that, weve looked at chlorides and one of the interesting things that goes into this wholetopic about wastewater, the wastewater side of this matter, because you know you have
what you see in the public all the time is the potential for groundwater contamination and the
potential for surface-water contamination. And infrequently, but more frequently now, whats
being discussed is the wastewater treatment. Thats a whole different issue, when people get
alarmed with the whole issue, they hear toxic contaminants and thats really. . . Its a matter of
concern, especially when youre talking about groundwater contamination and surface-water
contamination, because I think there are a few states out there that have had claims on both.
...
Me: Do you do any tests on radioactivity at all, do you know?
Bruce: I believe we tested once, and we got a very, very low. . . almost a. . . so low, it was
not. . . it was at least an indication of what might have been happening, but we dont do it on a
regular basis.
Me: As far as pretreatment, what do you treat for exactly?
Bruce: Well, actually, when we refer to pretreatment, the pretreatment program, according to
federal regulations, is a program that municipalities are required to manage and institute as
part of their entire infrastructure program, but the pretreatment program requires that industrypretreat their waste prior to discharge into the sewer system, or prior to discharge into the
receiving stream. So, theres some confusion out there about that, I believe. So, what we do at
the plant, is we do. . . nothing to pretreat wastewater that comes into our plant. The industrial
pretreatment program requires that we permit individual industries that are tributary to our
collection system. Do you understand what I mean?
Me: Yes.
Bruce: So, what we do is we issue them permits based on federal regulations. Based on the 40
part 403 regulations, if you wanna take a look at that, in the code of federal regulations. So, we
have an EPA approved pretreatment program. And as a matter of fact, a couple of years ago
the New York State DEC was recommending the City of Auburn, as well as anyone else with
a pretreatment program as receiving points for this water. But obviously what theyve done is
ratcheted that way down. And were one of the only plants, if not the only plant, that takes it in
the state now.
Me: Have you ever rejected any wastewater haulers?
-
8/3/2019 Onondaga Nation Comments on the 2011 Hydrofracking SGEIS
36/80
Bruce: Um, we have rejected wastewater. And again, its because we were told we cannot take
any more than what weve already taken. And again, one of the things thats made it difficult is
the game of musical chairs that the developers have been playing since this started, and the
controversy all hit the fan. Some companies have bought other companies, some companies
have stop discharging, some companies have pulled out of New York State. And so, you know,youve got a whole variety of scenarios happening with these companies. One I spoke with
recently had discharged any of the water they said they were going to take to us.
Me: As far as hydrofracking waste, have you ever received any from Pennsylvania?
Bruce: Yes, and we do right now. But we restrict water from the Marcellus formation, we do not
take water from the Marcellus formation. And we do not take water from horizontal fracturing,
we only take water from vertical wells.
Me: Can you give me an idea of what months, or around when, youve been accepting the
drilling fluids?
Bruce: Up until this year it had come every day. However, it varies. I couldnt tell you off the top
of my head how often it comes from Pennsylvania and how often it comes from New York.
Me: Is there an agreement that they have to sign, saying that they are not giving you horizontal
fracking waste?
Bruce: We put that in the permit, that theyre not to bring horizontal well water or anything from
the Marcellus formation. Thats whats built into the permit, anything that we restrict them is in
the permit. It appears that they have cooperated for the most part, um, we had some problemswith collecting the quarterly reports, because theyre not used to doing that. Theyre trying to
work now to tank their water because one of the problems with the water, the contents of the
water, is that they change over the life of the well. So, when they start, from start to finish, the
water is more dilute to more concentrated. So, youre gonna have more chlorides, and more
dissolved solids by the time the well is at completion. And so, we have limits on that we have
calculated, that we are trying to limit our plant. However, its a matter of constantly varying with
the well water, the volume that comes in. Its very tricky, and I think the reason most places
dont take it is because its a nightmare to try and control.

FAQs - Earthquakes, Faults, Plate Tectonics, Earth Structure
Previous FAQ | All FAQ's | Next FAQ
Q: Can we cause earthquakes? Is there any way to prevent earthquakes?
A: Earthquakes induced by human activity have been documented in a few locations in the United States, Japan, and Canada. The
cause was injection of fluids into deep wells for waste disposal and secondary recovery of oil, and the use of reservoirs for water
supplies. Most of these earthquakes were minor. The largest and most widely known resulted from f luid injection at the Rocky
Mountain Arsenal near Denver, Colorado. In 1967, an earthquake of magnitude 5.5 followed a series of smaller earthquakes. Injection
had been discontinued at the site in the previous year once the link between the fluid injection and the earlier series of earthquakes
was established. (Nicholson, Craig and Wesson, R.L., 1990, Earthquake Hazard Associated with Deep Well Injection--A Report to the
U.S. Environmental Protection Agency: U.S. Geological Survey Bulletin 1951, 74 p.)
Other human activities, even nuclear detonations, have not been linked to earthquake activity. Energy from nuclear blasts dissipates
quickly along the Earth's surface. Earthquakes are part of a global tectonic process that generally occurs well beyond the influence or
control of humans. The focus (point of origin) of earthquakes is typically tens to hundreds of miles underground. The scale and force
necessary to produce earthquakes are well beyond our daily lives. We cannot prevent earthquakes; however, we can significantly
mitigate their effects by identifying hazards, building safer structures, and providing education on earthquake safety.

SUBJECT: Revised Draft-Supplemental Generic Environmental Impact Statement(dSGEIS) on the Oil, Gas, and Solution Mining Regulatory Program-Well
Permit Issuance for Horizontal Drilling and High-Volume Hydraulic
Fracturing to Develop the Marcellus Shale and Other Low-PermeabilityReservoirs
___________________________________________________________________________
The New York Archaeological Council (NYAC) is a statewide association of New York
State professional archaeologists with over 100 members. Membership is primarily
comprised of professionals involved in cultural resource management. As cultural resource professionals, we are concerned with protecting and managing New Yorks cultural
resourcesarchaeological, historical, architectural and visual resources. On behalf ofNYAC membership, we wish to offer the following comments on the revised dSGEIS (dated
7 September 2011) for well permits to develop the Marcellus Shale gas fields throughout the
Southern Tier of New York State.
In 2008, NYAC outlined concerns of this industrys effect on cultural resources in regards to
well permitting (see attached comment letter). Our review of the 2008 dSGEIS document
determined that it did not adequately address adverse impacts to cultural resources, nor did itidentify a process compatible with the State and National Historic Preservation Acts that
would identify and protect cultural resources representing our Nations and States heritage.Given that none of our 2008 comments were integrated into the present revised dSGEIS,
there are identical, and serious, shortcomings with the 2011 revised dSGEIS. The currentrevised dSGEIS only focuses on known (visual) cultural resources, it does not acknowledge
the direct impacts (large scale earthmoving) that will threaten cultural resources, nor does it
identify a clear process for well permitting that ensures protection of New York Statescultural resources as a result of the industrys undertakings.

A serious omission in the revised dSGEIS is its failure to explicitly identify how compliance
with the State Historic Preservation Act (14.09 State Regulations, Part 426) of the Parks,
Recreation and Historic Preservation Act of 1980, Section 14.09 will be executed. The Actrequires state agencies to consult with the Office of Parks, Recreation and Historic
Preservation (OPRHP) if it appears that any projects being planned may or will cause any
change, beneficial or adverse, in the quality of any historic, architectural, archeological or
cultural property that is listed on the National Register of Historic Places or listed in the StateRegister or that is determined to be eligible for listing in the State Register. Furthermore, it
requires New York state agencies, to the fullest extent practicable, consistent with other
provisions of the law, to avoid or mitigate adverse impacts to such cultural properties, toexplore all feasible and prudent alternatives and to give due consideration to feasible and
prudent plans that would avoid or mitigate adverse impacts to such property.
The revised dSGEIS incorrectly subsumes all cultural resources under the category of visual
resources, only considers those historic resources listed or eligible for listing in the
State/National Register of Historic Places (Section 2.4.12), and fails to identify earth
moving/land clearing as an adverse impact to significant cultural resources. While culturalresources that are significant because of their visual qualities or aesthetics and cultural
view sheds are a legitimate concern during in the impact analysis, the revised dSGEIS fails to
identify and consider buried archaeological sites. A major omission in the revised dSGEIS isits failure to consider the potentially disastrous impacts earth moving/land clearing activities
associated with Marcellus Shale development will have on buried and unidentified
archaeological sites.
According to the revised dSGEIS, earth moving/land disturbance(s) associated with this
industry will include the construction of access roads, well pads, and utility corridors.
Other potential impacts discussed in the revised dSGEIS include cuttings pits, reserve pits,fresh water storage impoundments, and waste disposal. The average total disturbance
associated with a multi-well pad during the drilling and fracturing stage is estimated at 7.4
acres and a well pad for a single vertical well for the drilling and fracturing stage is estimated
at 4.8 acres (Section 5.1).
The significance of archaeological sites and other cultural resources important to New Yorks
history and people are unrelated to site size and sites can range from a several square feet(the size of a human grave) to multi-acre prehistoric villages or historic hamlets. The
industrys land disturbances estimates of 4.8-7.4 acres are large enough that entire sites could
be obliterated during land clearing activities required for hydraulic fracturing mining andinstallation or construction of related infrastructure needs.
Only a very small percentage, estimated at less than one percent, of New York has been
surveyed by professional archaeologists or by other cultural resource professionals. As aresult, only a small number of New Yorks known significant cultural resources are officially
recorded and/or listed in the State/National Register of Historic Places. Most New York
archaeological sites that could be affected by this industrys undertakings are buried,
encapsulated in sediments and soils below the ground surface, and as of yet, undiscovered.Because they have not been identified and are buried, archaeological sites can be destroyed
easily by heavy mechanized equipment movement and land clearing activities, both of which
are undeniable impacts linked to Marcellus Shale mining and associated infrastructure needs.

Many archaeological sites in the Southern Tier are at serious risk of destruction from this
industrys actions because: earth moving/land disturbance is a routine and unavoidable part
of this industrys activities; not all significant archaeological sites have been identified andthey can exist below ground; and there are no proactive measures in the revised dSGEIS that
outline how archaeological sites will be identified and protected in the permitting process.
To resolve this threat, we strongly urge NYSDEC to incorporate measures into the permitting
process that comply with the State and National Historic Preservation Act directives toidentify and protect cultural resources by professional archaeologists (36 CFR 61 qualified)
before permits are issued for the industrys undertakings.
Considering the important issues discussed above that are critical for protecting New Yorks
significant cultural resources from activities associated with Marcellus Shale mining, we
recommend that the following be included in the final dSGEIS sections:
CHAPTER 1-Introduction, Section 1.2 Regulatory Jurisdiction
Protection of cultural resources needs to be included in this section. manage natural and cultural resources to assure their protection and balanced utilization;
CHAPTER 2-Destription of Proposed Action, Section 2 Visual Resources
All cultural resources are incorrectly subsumed under a category termed visual resources.
This section needs to renamed Cultural Resources and include a comprehensive list of the
resources that are commonly associated with New Yorks history (archaeological, historical,structures, traditional cultural places, commemorative and traditional cultural places, objects,
districts, objects, artifacts, etc.) , that could be adversely affected by the activities associated
with Marcellus Shale mining and related activities.
As written, the revised dSGEIS only considers cultural resources already recorded/listed.
The final dSGEIS should explicitly state that all cultural resources, known and unknown (i.e.,
undiscovered) need to be considered and protected.
Earth moving/land clearing needs to be explicitly identified as a potential adverse impact to
cultural resources.
CHAPTER 3 SEQRA Process
This section needs to discuss compliance with the State Historic Preservation Act (14.09
State Regulations, Part 426) of the Parks, Recreation and Historic Preservation Law.
Specifically, the well permitting process must include coordination with the NYSDEC
Agency Preservation Officer and OPRHP to determine which impacts, direct and indirect,that may be significant in terms of cultural resources.
CHAPTER 6 Potential Environmental Impacts
A separate section is needed to consider all potential impacts, direct and indirect, to all
cultural resources/cultural properties including buried archaeological sites. Earth
moving/land clearing needs to be explicitly identified as a direct and potential adverse impact
-
8/3/2019 Onondaga Nation Comments on the 2011 Hydrofracking SGEIS

4
to cultural resources. Direct impacts constitute all earth moving/land clearing activities
required for well drilling (e.g., well pads, access roads, lined pits, injection pits, etc.).
Indirect impacts (e.g., vibration, soil compaction, chemical contamination, etc.) also need to be listed in this section. Indirect impacts have great potential to diminish the integrity of
known or not yet discovered archaeological sites and need to be considered in the permitting
process.
CHAPTER 7 Existing and Recommended Mitigation Measures, Section 7.9-Visial
Mitigation Measures
As written, the revised dSGEIS only takes into account visual (above ground) resources. A
separate section needs to be added under Mitigation Measures to address mitigation of
archaeological (below ground) resources. In most cases, high volume hydraulic fracturingoperations and related activities would not result in significant adverse impacts on visual
resources. However, even a small amount of earth moving/land clearing can severely impact
buried archaeological resources. Mitigation measures related to earth movings effect on
(buried/below ground) cultural resources (e.g., prehistoric and historic archaeological sites)and other types of cultural resources needs to be explicitly stated.
CHAPTER 8 Permit Processing and Regulatory Coordination, Section 8.1.1.1 SEQRAParticipation
In Table 8.1: Regulatory Jurisdictions Associated With High-Volume Hydraulic Fracturing
(Updated August 2011), OPRHP involvement only is listed for well siting and newindustrial treatment plants and only listed as role pertains in certain circumstances which
are not defined. Again, compliance with the State Historic Preservation Act needs to be part
of the permitting process.
OPRHP involvement should be listed for all earth moving/land clearing activities shown on
Table 8.1, since these are the most likely to have adverse impact to significant (below
ground) cultural resources. The NYDEC should consult with the OPRHP to determine thesensitivity of construction areas proposed for mining and associated activities and assess the
need to conduct cultural resource investigations before permits are issues.
CHAPTER 11 Summary of Potential Impacts and Proposed Mitigation Measures, Table
11.1 Summary of Potential Impacts and Proposed Mitigation Measures
Cultural resources need to be listed as resources that will be affected by this industrys
activities.
Potential mitigation measures for cultural resources would include: A phased approach toidentify, evaluate, and mitigate significant archaeological sitesi.e., Phase I archaeological
identification surveys, Phase II National Register of Historic Places (NRHP) archaeological
site evaluations and Phase III archaeological site mitigations; architectural recordation; and
consultation with OPRHP and Native Americans, or other groups, who have interest inproperty or places that are rooted their community or cultural groups history.

Life of a Well The gas industry considers the life of a well interms of its productive life, which typically ranges between 4and 20 years. This is the time period when isolation of gas-richformations from the overlying freshwater aquifers mattersmost to them. Loss of zonal isolation equates directly to loss ofprofits because the gas is not captured. When a gas well is nolonger profitable, it is plugged and abandoned. Plugginginvolves removal of an inner steel casing placed during wellconstruction and then cementing of the open borehole to sealoff gas bearing and saline geologic horizons from the over-lying freshwater aquifer. To provide long-term protection,the cement sheath, casing, and inner cement plug must remainfully intact for the life of the aquifer (999,980+ years).
Life of Cement & Life of Steel Long-term protection of freshwateraquifers from deep, contaminant-laden, bedrock formations breached by gaswells relies completely on the durability of the materials used to physically
isolate them. Water quality protection must be viewed relative to the life ofaquifers. Therefore, sealant materials must also have a design life equal to theuseful life of aquifers. Extensive research conducted by the gas industry andothers reveals that cement failure will occur in less than 100 years due tonumerous factors that include shrinkage, debonding, and the development ofchannels that allow gas and fluid migration. Debonding occurs at the casing/bedrock and cement/casing interfaces. A micro-annulus of 0.001 inches issufficient to allow gas flow. Similarly, research shows that steel casing alsohas a design life of less than 80 years - in some cases far less due to exposureto saline water and acid gases (i.e., < 4 years). Thereafter, material failureand groundwater degradation are assured.
Life of Aquifers Through geologic time, layers of sedimentswere deposited and compacted into bedrock. The land was sub-sequently uplifted and then eroded for over 1,000,000 years bythe Delaware River and its many tributaries. In response, freshgroundwater flow now moves slowly from upland areas towardsvalleys. These freshwater aquifers are physically isolated and farabove deep, saline, waters and gas-rich bedrock formations.Wells tap the pure freshwater aquifers we drink from. Gas wellspose a real threat to well water quality because they provide un-natural pathways for contaminants to rise under pressure fromdeep within the earth and to mix with potable water. If saline andfreshwater zones remain disconnected, our aquifers will continueto provide pristine water to our children and their grandchildrenfor another 1,000,000 plus years. If the two become connected,the results would be devastating for future generations - robbingthem of needed groundwater.

Fracture Sets Are Connected Over Thousands Of Feet The above hydrograph documentsthe hydraulic response of observation wells B and C from pumping well A. The schematic set-up of theorientation of these wells relative to themselves and a major stream is depicted on the figure above.Well B is 2,100 feet NW of Well A and Well C is 1,000 feet to the west. Observation Well B is situated
on the opposite side of a valley, beyond a major Delaware River tributary that hydrologists might haveconsidered to be a significant groundwater divide (see also front page figure). This test demonstratesthat pressurized methane-rich waters can impact water supplies across major groundwater divides indifferent watersheds - anywhere along open, permeable, portions of fractures.
Rapid Contamination of Homeowner Wells Methane excursions from gas wells constructedalong the same fracture set as homeowner wells will contaminate drinking water supplies. This willoccur when zonal isolation sealant materials fail, in a time frame ranging from days to 100 years.

Setback Distances From Water Bodies & Homeowner Wells Analysis of hydrologic datareveals that gas well array (i.e., multiple horizontal boreholes stemming from a single well pad) setbackdistances of less than 2,100 feet from water bodies (e.g., reservoirs, lakes, rivers, streams, wetlands) andhomeowner wells may pose a significant water quality risk. DRBC draft gas drilling regulations propose asetback distance of 500 feet between vertical boreholes and water bodies. This distance appears to lack theempirical data needed to document that it will protect water resources. One key hydrogeologic factorinvolved is whether cement sheath failure coincident with hydrofracking events and well decommissioningwill result in rapid transmission of 1) pressurized methane, Light Non-Aqueous Phase Liquids (LNAPLs),
and other pollutants to homeowner wells and water bodies, and 2) free and dissolved gas flow throughleaking well annuli and fractures during gas production. Pumping tests and analyses of known contaminantincidents provide a means of assessing this. Pumping tests that stress groundwater within fractured bedrockaquifers provide a rigorous means of assessing fracture interconnectivity. The hydrograph of a pumping test(below) conducted in the Delaware River Basin documented the effects of turning a pumping well on andoff in less than five minutes in observation wells up to 2,100 feet away. Because this documents long-distance hydraulic connections, it is likely that contaminants driven by high pressures during hydraulicfracturing events and after well decommissioning will adversely impact wells. There is also evidence thatmethane is released from fractures and wellbores at far greater distances. In addition, some fractures naturallyrelease methane. Because hydraulic fracturing within gas well arrays may interconnect these fractures,it would, from a water quality protection standpoint, be prudent to expand the setback distance beyond thewell array. Pumping test data provides solid documentation for mandating minimum setback distanceto at least 2,100 feet as measured from the outer boundary of well arrays to all water resourcesand homeowner wells.

Directional drilling and hydraulic-fracturing technologies are dra-
matically increasing natural-gas extraction. In aquifers overlying
the Marcellus and Utica shale formations of northeastern Pennsyl-
vania and upstate New York, we document systematic evidence for
methane contamination of drinking water associated with shale-
gas extraction. In active gas-extraction areas (one or more gas
wells within 1 km), average and maximum methane concentrations
in drinking-water wells increased with proximity to the nearest
gas well and were 19.2 and 64 mg CH4 L1 (n 26), a potential
explosion hazard; in contrast, dissolved methane samples in neigh-
boring nonextraction sites (no gas wells within 1 km) within similargeologic formations and hydrogeologic regimes averaged only
1.1 mgL1 (P < 0.05; n 34). Average 13C-CH4 values of dissolved
methane in shallow groundwater were significantly less negative
for active than for nonactive sites (37 7 and 54 11,
respectively; P < 0 .0001). These 13C-CH4 data, coupled with the ra-
tios of methane-to-higher-chain hydrocarbons, and2H-CH4 values,
are consistent with deeper thermogenic methane sources such asthe Marcellus and Utica shales at the active sites and matched gas
geochemistry from gas wells nearby. In contrast, lower-concentra-
tion samples from shallow groundwater at nonactive sites had
isotopic signatures reflecting a more biogenic or mixed biogenic/
thermogenic methane source. We found no evidence for contam-
ination of drinking-water samples with deep saline brines or frac-
turing fluids. We conclude that greater stewardship, data, andpossiblyregulation are needed to ensure the sustainable future
of shale-gas extraction and to improve public confidence in its use.

Increases in natural-gas extraction are being driven by risingenergy demands, mandates for cleaner burning fuels, and theeconomics of energy use (15). Directional drilling and hydrau-lic-fracturing technologies are allowing expanded natural-gasextraction from organic-rich shales in the United States and else-
where (2, 3). Accompanying the benefits of such extraction (6, 7)are public concerns about drinking-water contamination fromdrilling and hydraulic fracturing that are ubiquitous but lack a
strong scientific foundation. In this paper, we evaluate the poten-tial impacts associated with gas-well drilling and fracturing onshallow groundwater systems of the Catskill and Lockhavenformations that overlie the Marcellus Shale in Pennsylvania andthe Genesee Group that overlies the Utica Shale in New York(Figs. 1 and 2 and Fig. S1). Our results show evidence formethane contamination of shallow drinking-water systems in atleast three areas of the region and suggest important environmen-tal risks accompanying shale-gas exploration worldwide.
The drilling of organic-rich shales, typically of Upper Devo-nian to Ordovician age, in Pennsylvania, New York, and else-
where in the Appalachian Basin is spreading rapidly, raisingconcerns for impacts on water resources (8, 9). In SusquehannaCounty, Pennsylvania alone, approved gas-well permits in theMarcellus formation increased 27-fold from 2007 to 2009 (10).
Concerns for impacts to groundwater resources are based on(i) fluid (water and gas) flow and discharge to shallow aquifersdue to the high pressure of the injected fracturing fluids in thegas wells (10); (ii) the toxicity and radioactivity of produced waterfrom a mixture of fracturing fluids and deep saline formation
waters that may discharge to the environment (11); (iii) thepotential explosion and asphyxiation hazard of natural gas; and(iv) the large number of private wells in rural areas that rely onshallow groundwater for household and agricultural useup toone million wells in Pennsylvania alonethat are typically unre-gulated and untested (8, 9, 12). In this study, we analyzed ground-
water from 68 private water wells from 36- to 190-m deep in

northeast Pennsylvania (Catskill and Lockhaven formations) andupstate New York (Genesee formation) (see Figs. 1 and 2 and SIText), including measurements of dissolved salts, water isotopes(18O and 2H), and isotopes of dissolved constituents (carbon,boron, and radium). Of the 68 wells, 60 were also analyzed fordissolved-gas concentrations of methane and higher-chain hydro-carbons and for carbon and hydrogen isotope ratios of methane.
Although dissolved methane in drinking water is not currentlyclassified as a health hazard for ingestion, it is an asphyxiant inenclosed spaces and an explosion and fire hazard (8). This studyseeks to evaluate the potential impact of gas drilling and hydrau-lic fracturing on shallow groundwater quality by comparing areasthat are currently exploited for gas (defined as activeone or
more gas wells within 1 km) to those that are not currently asso-ciated with gas drilling (nonactive; no gas wells within 1 km),many of which are slated for drilling in the near future.
Results and Discussion
Methane concentrations were detected generally in 51 of 60drinking-water wells (85%) across the region, regardless of gasindustry operations, but concentrations were substantially highercloser to natural-gas wells (Fig. 3). Methane concentrations
were 17-times higher on average (19.2 mg CH4 L1) in shallow
wells from active drilling and extraction areas than in wells fromnonactive areas (1.1 mg L1 on average; P< 0.05; Fig. 3 andTable 1). The average methane concentration in shallow ground-
water in active drilling areas fell within the defined action level(1028 mg L1) for hazard mitigation recommended by the US
Office of the Interior (13), and our maximum observed value of64 mg L1 is well above this hazard level (Fig. 3). Understandingthe origin of this methane, whether it is shallower biogenic ordeeper thermogenic gas, is therefore important for identifyingthe source of contamination in shallow groundwater systems.
The 13C-CH4 and 2H-CH4 values and the ratio of methane to
higher-chain hydrocarbons (ethane, propane, and butane) can ty-pically be used to differentiate shallower, biologically derivedmethane from deeper physically derived thermogenic methane(14). Values of13C-CH4 less negative than approximately50are indicative of deeper thermogenic methane, whereas valuesmore negative than 64 are strongly indicative of microbialmethane (14). Likewise, 2H-CH4 values more negative thanabout 175, particularly when combined with low 13C-CH4
values, often represent a purer biogenic methane origin (14).
The average 13C-CH4 value in shallow groundwater in activedrilling areas was 37 7, consistent with a deeper thermo-genic methane source. In contrast, groundwater from nonactiveareas in the same aquifers had much lower methane concentra-tions and significantly lower 13C-CH4 values (average of5411; P< 0.0001; Fig. 4 and Table 1). Both our 13C-CH4 dataand 2H-CH4 data (see Fig. S2) are consistent with a deeper ther-mogenic methane source at the active sites and a more biogenicor mixed methane source for the lower-concentration samplesfrom nonactive sites (based on the definition of Schoell, ref. 14).
Because ethane and propane are generally not coproduced
during microbial methanogenesis, the presence of higher-chainhydrocarbons at relatively low methane-to-ethane ratios (lessthan approximately 100) is often used as another indicator ofdeeper thermogenic gas (14, 15). Ethane and other higher-chainhydrocarbons were detected in only 3 of 34 drinking-water wellsfrom nonactive drilling sites. In contrast, ethane was detected in21 of 26 drinking-water wells in active drilling sites. Additionally,propane and butane were detected (>0.001 mol %) in eight andtwo well samples, respectively, from active drilling areas but in no
wells from nonactive areas.Further evidence for the difference between methane from
water wells near active drilling sites and neighboring nonactivesites is the relationship of methane concentration to 13C-CH4
values (Fig. 4A) and the ratios of methane to higher-chain hydro-

carbons versus 13C-CH4 (Fig. 4B). Methane concentrations notonly increased in proximity to gas wells (Fig. 3), the accompany-ing 13C-CH4 values also reflected an increasingly thermogenicmethane source (Fig. 4A).
Using a Bernard plot (15) for analysis (Fig. 4B), the enriched13C-CH4 (approximately > 50) values accompanied by
low ratios of methane to higher-chain hydrocarbons (less thanapproximately 100) in drinking-water wells also suggest that dis-solved gas is more thermogenic at active than at nonactive sites(Fig. 4B). For instance, 12 dissolved-gas samples at active drillingsites fell along a regional gas trajectory that increases with reser-
voir age and thermal maturity of organic matter, with samplesfrom Susquehanna County, Pennsylvania specifically matching
natural-gas geochemistry from local gas wells (Fig. 4B, orangeoval). These 12 samples and local natural-gas samples are con-sistent with gas sourced from thermally mature organic matterof Middle Devonian and older depositional ages often foundin Marcellus Shale from approximately 2,000 m below the surfacein the northern Appalachian Basin (1419) (Fig. 4B). In contrast,none of the methane samples from nonactive drilling areas fellupon this trajectory (Fig. 4B); eight dissolved-gas samples inFig. 4B from active drilling areas and all of the values from non-active areas may instead be interpreted as mixed biogenic/thermogenic gas (18) or, as Laughrey and Baldassare (17) pro-posed for their Pennsylvanian gas data (Fig. 4B), the early migra-tion of wet thermogenic gases with low-13C-CH4 values andhigh methane-to-higher-chain hydrocarbon ratios. One datapoint from a nonactive area in New York fell squarely in the para-
meters of a strictly biogenic source as defined by Schoell (14)(Fig. 4B, upper-left corner).
Carbon isotopes of dissolved inorganic carbon (13C-DIC >10) and the positive correlation of 2H of water and 2Hof methane have been used as strong indicators of microbialmethane, further constraining the source of methane in shallowgroundwater (depth less than 550 m) (18, 20). Our 13C-DIC
values were fairly negative and show no association with the13C-CH4 values (Fig. S3), which is not what would be expectedif methanogenesis were occurring locally in the shallow aquifers.Instead, the 13C-DIC values from the shallow aquifers plot
within a narrow range typical for shallow recharge waters, withthe dissolution of CO2 produced by respiration as water passesdownward through the soil critical zone. Importantly, these
values do not indicate extensive microbial methanogenesis orsulfate reduction. The data do suggest gas-phase transport ofmethane upward to the shallow groundwater zones sampled forthis study (250;000 mg L1, trace

toxic elements, (18), and naturally occurring radioactive materi-als, with activities as high as 16;000 picocuries per liter(1 pCi L1 0.037 becquerels per liter) for 226Ra compared toa drinking-water standard of5 pCi L1 for combined 226Ra and226Ra (23).
We evaluated the hydrochemistry of our 68 drinking-water wells and compared these data to historical data of 124 wellsin the Catskill and Lockhaven aquifers (24, 25). We used threetypes of indicators for potential mixing with brines and/or saline
fracturing fluids: (i) major inorganic chemicals; (ii) stable isotopesignatures of water (18O, 2H); and (iii) isotopes of dissolvedconstituents (13C-DIC, 11B, and 226Ra). Based on our data(Table 2), we found no evidence for contamination of the shallow
wells near active drilling sites from deep brines and/or fracturingfluids. All of the Na, Cl, Ca2, and DIC concentrations in
wells from active drilling areas were consistent with the baselinehistorical data, and none of the shallow wells from active drillingareas had either chloride concentrations >60 mg L1 or Na-Ca-Cl compositions that mirrored deeper formation waters (Table 2).Furthermore, the mean isotopic values of 18O, 2H, 13C-DIC,11B, and 226Ra in active and nonactive areas were indistinguish-able. The 226Ra values were consistent with available historicaldata (25), and the composition of18O and 2H in the well-waterappeared to be of modern meteoric origin for Pennsylvania(26) (Table 2 and Fig. S5). In sum, the geochemical and isotopicfeatures for water we measured in the shallow wells from bothactive and nonactive areas are consistent with historical dataand inconsistent with contamination from mixing Marcellus Shaleformation water or saline fracturing fluids (Table 2).
There are at least three possible mechanisms for fluid migra-tion into the shallow drinking-water aquifers that could helpexplain the increased methane concentrations we observed neargas wells (Fig. 3). The first is physical displacement of gas-richdeep solutions from the target formation. Given the lithostaticand hydrostatic pressures for 12 km of overlying geological stra-ta, and our results that appear to rule out the rapid movement ofdeep brines to near the surface, we believe that this mechanismis unlikely. A second mechanism is leaky gas-well casings (e.g.,
refs. 27 and 28). Such leaks could occur at hundreds of metersunderground, with methane passing laterally and verticallythrough fracture systems. The third mechanism is that the processof hydraulic fracturing generates new fractures or enlarges exist-ing ones above the target shale formation, increasing the connec-
tivity of the fracture system. The reduced pressure following thefracturing activities could release methane in solution, leading tomethane exsolving rapidly from solution (29), allowing methanegas to potentially migrate upward through the fracture system.
Methane migration through the 1- to 2-km-thick geologicalformations that overlie the Marcellus and Utica shales is lesslikely as a mechanism for methane contamination than leaky wellcasings, but might be possible due to both the extensive fracturesystems reported for these formations and the many older, un-
cased wells drilled and abandoned over the last century and a halfin Pennsylvania and New York. The hydraulic conductivity in theoverlying Catskill and Lockhaven aquifers is controlled by a sec-ondary fracture system (30), with several major faults and linea-ments in the research area (Fig. 2 and Fig. S1). Consequently, thehigh methane concentrations with distinct positive 13C-CH4 and2H-CH4 values in the shallow groundwater from active areascould in principle reflect the transport of a deep methane sourceassociated with gas drilling and hydraulic-fracturing activities. Incontrast, the low-level methane migration to the surface ground-
water aquifers, as observed in the nonactive areas, is likely a nat-ural phenomenon (e.g., ref. 31). Previous studies have shownthat naturally occurring methane in shallow aquifers is typicallyassociated with a relatively strong biogenic signature indicatedby depleted 13C-CH4 and
2H-CH4 compositions (32) coupledwith high ratios of methane to higher-chain hydrocarbons (33), aswe observed in Fig. 4B. Several models have been developed toexplain the relatively common phenomenon of rapid verticaltransport of gases (Rn, CH4, and CO2) from depth to the surface(e.g., ref. 31), including pressure-driven continuous gas-phaseflow through dry or water-saturated fractures and density-drivenbuoyancy of gas microbubbles in aquifers and water-filled frac-tures (31). More research is needed across this and other regionsto determine the mechanism(s) controlling the higher methaneconcentrations we observed.
Based on our groundwater results and the litigious nature ofshale-gas extraction, we believe that long-term, coordinated sam-pling and monitoring of industry and private homeowners isneeded. Compared to other forms of fossil-fuel extraction, hy-
draulic fracturing is relatively poorly regulated at the federal level.Fracturing wastes are not regulated as a hazardous waste underthe Resource Conservation and Recovery Act, fracturing wellsare not covered under the Safe Drinking Water Act, and only re-cently has the Environmental Protection Agency asked fracturing

firms to voluntarily report a list of the constituents in the fractur-ing fluids based on the Emergency Planning and CommunityRight-to-Know Act. More research is also needed on the mechan-ism of methane contamination, the potential health consequencesof methane, and establishment of baseline methane data in otherlocations. We believe that systematic and independent data ongroundwater quality, including dissolved-gas concentrations andisotopic compositions, should be collected before drilling opera-tions begin in a region, as is already done in some states. Ideally,
these data should be made available for public analysis, recogniz-ing the privacy concerns that accompany this issue. Such baselinedata would improve environmental safety, scientific knowledge,and public confidence. Similarly, long-term monitoringof ground-
water and surface methane emissions during and after extractionwouldclarify the extent of problems andhelp identify the mechan-isms behind them. Greater stewardship, knowledge, andpossi-blyregulation are needed to ensure the sustainable future ofshale-gas extraction.
Methods
A total of 68 drinking-water samples were collected in Pennsylvania and New
York from bedrock aquifers (Lockhaven, 8; Catskill, 47; and Genesee, 13) that
overlie the Marcellus or Utica shale formations (Fig. S1). Wells were purged
to remove stagnant water, then monitored for pH, electrical conductance,
and temperature until stable values were recorded. Samples were collected
upstream of any treatment systems, as close to the water well as possible,
and preserved in accordance with procedures detailed in SI Methods.
Dissolved-gas samples were analyzed at Isotech Laboratories and water
chemical and isotope (O, H, B, C, Ra) compositions were measured at Duke
University (see SI Methods for analytical details).

the mortgage. The property owner can be particularlyvulnerable when the drilling process involves high-volume, horizontal hydraulic fracturing, or fracking.
For example, when Ellen Harrison signed a gas leaseagreement in 2008, the company representative made nomention of fracking. Harrison received no details, onlythe chance for a win-win with clean gas for the localsand royalties for her. Like most Americans, Harrison hasa mortgage loan secured by her home. All mortgages,Harrisons included, prohibit hazardous activity andhazardous substances on the property.
The ConundrumGas companies covet the shale gas deposits lying underhomes and farms in New Yorks Marcellus Shale regionand are pursuing leasing agreements with area propertyowners. Many homeowners and farmers in need of cashare inclined to say yes. In making their argument, gascompanies reassure property owners that the drillingprocesses and chemicals used are safe. Yet aside fromarguments about the relative safety of the extractionprocess are issues not often discussed, such as theowners potential liability and the continued viability of

wastewater, with concentrated levels of these toxicchemicals, drilling mud, bore clippings and naturallyoccurring radioactive material, such as uranium, radium226 and radon, is released from the well into mud pits andholding tanks, then trucked out for waste treatment orreused. Reuse of frack fluid, currently the favored practice
because it spares the finite water supply, concentrates thewaste toxicity. The Environmental Protection Agencyestimates that 20%40% of the fracking wastewaterstays underground. The Marcellus Shale sits amid anintricate network of underground aquifers that supplydrinking water in New York and surrounding states viamunicipal water supplies, private wells and springs.Shallow private wells constitute the primary source ofdrinking water for the upstate New York residences andfarms where fracking for shale gas would take place,posing a cumulative threat to the states complex matrixof aquifers that source our groundwater.
The RisksThe use of fracking expanded in 2005 when Congressexempted it through statutory amendments fromcomplying with decades-old federal environmentallaws governing safe drinking water and clean air. (Thisexemption is now commonly known as the Halliburtonloophole.) Also in 2005, New York changed its compulsoryintegration law to pave the way for fracking.
According to the 2010 Form 10-Ks of ChesapeakeEnergy and Range Resources (both doing business in theMarcellus Shale region), natural gas operations are subject
to many risks, including well blow-outs, craterings,explosions, pipe failures, fires, uncontrollable flows ofnatural gas or well fluids, formations with abnormalpressures and other environmental hazards and risks.Drilling operations, according to Chesapeake, involverisks from high pressure and mechanical difficulties suchas stuck pipes, collapsed casings and separated cables.If any of these hazards occur it can result in injury orloss of life, severe damage or destruction of property,natural resources and equipment, pollution or otherenvironmental damage and clean-up responsibilities,1 allin the homeowners backyard.
