This article explores Cancer Alley, an 85-mile stretch in Louisiana that epitomizes the intersection of environmental justice and industrial development, where predominantly Black communities face disproportionate health risks from a high concentration of petrochemical plants and refineries.
Hazardous air emissions in Pennsylvania are often hidden, leaking from abandoned wells, seeping from pipelines, and wafting invisibly into the air. This analysis utilizes new technologies and mapping tools to reveal the full scope of the problem and identify areas of particular concern in the state.
There is a need for more research on the human impact of the oil and gas industry in North Dakota, particularly on landowners and farmers, to understand their experiences and address their concerns effectively.

Unconventional oil and natural gas development, or “fracking,” began in Pennsylvania in the early 2000s. Since then, over 12,000 unconventional wells have been drilled in the state, and over 15,000 violations have been documented at unconventional well sites. As fracking operations continue to expand, increasing numbers of residents have experienced significant health impacts and irreparable damage to their property. Southwest Pennsylvania in particular has been heavily impacted, with high concentrations of oil and gas infrastructure developed in Washington, Greene, and Fayette Counties.
Fracking operations have led to declining air quality, water and soil contamination, and drastic changes to the physical landscape including deforestation, habitat fragmentation, road construction, and damaged farmland. While the volume of scientific literature about the physical and mental health impacts of fracking is rising, few studies exist that specifically focus on residents’ perceptions of the changing physical landscape. The primary goal of this qualitative study was to identify residents’ attitudes about the changing physical landscape resulting from fracking operations. Furthermore, how have these landscape changes affected residents’ engagement with the outdoors and their overall health?
Many scientific studies have documented the relationship between fracking developments and mental health, and between mental health and access to green spaces and engagement with the outdoors. Peer-reviewed studies have looked at heavily fracked communities across the US, many of which focus on Pennsylvania residents. Methods typically involve one-on-one interviews, larger focus groups, surveys, or a combination of the three, to identify how living amongst oil and gas operations takes a toll on everyday life. These studies have found an increase in stress and anxiety, feelings of powerlessness against the oil and gas industry, social conflicts, sleep disturbances, and reduced life satisfaction. Additionally, residents have experienced disruptions in their sense of place and social identity. For a summary of published research about the mental health impacts from fracking, click here.
A healthy strategy many choose to cope with stress and anxiety is engagement in outdoor recreation. Having easily accessible “green spaces,” or land that is partly or completely covered with grass, trees, shrubs, or other vegetation such as parks and conservation areas have been shown to promote physical and mental health. Many scientific studies have identified significantly fewer symptoms of depression, anxiety, and stress in populations with higher levels of neighborhood green space.1 Additionally, green spaces can aid recovery from mental fatigue and community social cohesion.2 3 However, residents in Southwestern Pennsylvania may slowly see their access to green spaces and opportunities for outdoor recreation decline due to the expansion of fracking operations. Figure 1 below shows a visual representation of the interconnected relationship between fracking, access to green spaces, and negative mental health impacts.
Figure 1. The interconnected relationship between fracking operations, landscape changes and decreasing access to outdoor recreation, and negative mental health impacts.
In the last 10-15 years, fracking operations in Southwest Pennsylvania have exploded. The development of new pipelines, access roads, well pads, impoundments, and compressor stations is widespread and altering the physical landscape. Figure 2 below illustrates just one of many examples of landscape disruption caused from fracking operations.

A qualitative study was conducted to answer the following research questions:
To better understand these topics, residents living in Southwestern Pennsylvania were recruited to participate in one-on-one phone interviews, and an online survey was also distributed throughout the FracTracker Alliance network. Recruitment for the one-on-one phone interviews was accomplished through FracTracker’s social media, and email blasts through other partnering organizations such as Halt the Harm Network, People Over Petro, and the Clean Air Council. Similarly, the online survey was shared on FracTracker’s social media and also distributed through our monthly newsletter. Since this was not a randomized sample to select participants, these results should not be generalized to all residents living near oil and gas infrastructure. However, this study identifies how certain individuals have been impacted by the changing landscape brought about by fracking operations.
Eight residents completed phone interviews, all of whom resided in Washington County, PA. Residents were first asked how long they have lived in their current home, and if there was oil and gas infrastructure on or near their property. Oil and gas infrastructure was defined as well pads, compressor stations, pipelines, ponds or impoundments, or access roads. Next, residents were asked if they had any health concerns regarding fracking operations and gave personal accounts of how fracking operations have altered the physical landscape near their home and in their surrounding community. For those with agricultural land, additional questions were asked about fracking’s impact on residents’ ability to use their farmland. Lastly, residents were asked questions focused on engagement in outdoor recreation and if fracking had any impact on outdoor recreation opportunities. NVivo, a qualitative analysis software, was used identify emergent themes throughout the interviews,
In addition to the interviews, an online survey was also made available.The main purpose of the survey was to gauge where concerns about landscape changes from fracking operations fell in relation to other oil and gas impacts (i.e. air pollution, water contamination, excess noise and traffic, and soil contamination). Nine responses were recorded, and the results are discussed below. However, if you would like to add your thoughts, you can find the survey at https://www.surveymonkey.com/r/Z5DCWBD.
Various emergent themes surrounding the oil and gas industry’s impact on public health and the environment were identified throughout the resident interviews. Residents shared their personal experiences and how they have been directly impacted by fracking operations, especially with reference to the changing physical landscape surrounding their homes and throughout their communities. Participants’ time of residence in Washington County ranged from 3 years to their entire life, and all participants had oil and gas infrastructure (well pad, pipelines, impoundment, access roads, or compressor station) on or next to their property.
The first overarching theme was changes to the physical landscape and residents’ attitudes toward the altered environment. All interview participants expressed concerns about the changes to the physical landscape on or surrounding their property, especially regarding access roads and well pads. Although one participant mentioned that widening the township road in order to make room for fracking trucks benefited the local community, the majority of participants expressed frustration about the construction of access roads, excessive truck traffic, noise, and dust from the unpaved access roads. One individual stated, “My main concern is the dust from the road. I’m constantly breathing that in, and it’s all over my shed, on the cars, the inside of the house, the outside of the house.” Multiple participants discussed the oil and gas operations disrupting what was once peaceful farmland with beautiful scenery (see an example in Figure 4 below). Another individual stated, “And of course, the noise is just unbearable. They don’t stop…the clanging on the pipe, the blow off with the wells, pumps running, generators, trucks coming down the hill with their engine brakes on, blowing their horn every time they want another truck to move.”

Impacts to outdoor recreation activities such as hunting, fishing, and hiking were another recurring theme throughout the interviews. Again, a majority of participants believed their opportunities to partake in outdoor recreation have been limited since fracking operations began in their area.
Among the top concerns was deteriorating air quality and increasing numbers of ozone action days, or days when the air quality index (AQI) for ozone reaches an unhealthy level for sensitive populations. Various participants expressed concerns about letting their children outside due to harmful air emissions and odors originating from well pads or compressor stations. Excessive truck traffic was also a safety concern that was mentioned, especially for those individuals with access roads on or neighboring their property.
Additionally, one individual noted landscape changes in areas commonly used for hiking stating, “You might be hiking along a trail and then realize that you’re no longer on the trail. You’re actually on a pipeline cut. Or you’ll get confused while you’re hiking because you’ll intersect with a road that was developed for a well pad, and it’s not on your map.” Along with hiking, participants also noted a change in hunting and fishing opportunities since fracking moved into the region. Concerns were expressed regarding harvesting any fish or wild game due to possible contamination from fracking chemicals, especially near watersheds with known chemical spills.
Going for a hike and immersing oneself in nature is a healthy way to unwind and relieve stress. However, a rising number of well pads and compressor stations are put in place near parks, hiking trails, and state game lands throughout Southwest Pennsylvania (Figure 5). Participants expressed concerns about feeling unable to escape oil and gas infrastructure, even when visiting these recreational areas. As one individual mentioned, “It really does change your experience of the outdoors. And, you know, it’s an area that’s supposed to be a protected natural area. Then you know you can’t really get away. Even there in public lands far away from buildings and roads. And you can’t really get away from it.”

But what are the mental health impacts that result from the changing physical landscape brought about by fracking? Aside from the physical health effects caused by fracking activity — such as respiratory illnesses from air pollution or skin irritation from contaminated well water — these landscape changes have taken a toll on participants’ mental health as well.
Many participants described the sentimental value of their property, and the beautiful scenery surrounding their generational family farms. But after fracking began on neighboring property, witnessing their tranquil family farm suddenly become surrounded by dusty access roads, excessive truck traffic, noise, and deteriorating air quality took a serious emotional and mental toll. When asked about the impact of the changing landscape, one participant stated, “It’s the emotional part of watching her childhood farm being destroyed while she is trying to do everything she can to rebuild it to the way it used to be.”
An additional emergent theme surrounding fracking landscape changes was surrounding agricultural impacts. Participants with agricultural land were asked additional questions about fracking’s impacts on their ability to use their farmland. One individual noted that one of their fields was now unusable due to large rocks and filter fabrics left from construction of a well pad, and redirected runoff uphill of their fields. The loss of productive farmland has further contributed to the mental and emotional stress. One participant added, “Our house is ruined, our health is ruined, and our farms are ruined.” In addition to agricultural impacts on large farms, multiple participants also mentioned concerns about their smaller-scale gardens, citing uncertainty about the impacts of air pollution and soil contamination on their produce.
Some participants mentioned feelings of powerlessness against the oil and gas industry. Many families were not consulted prior to fracking operations beginning adjacent to their property. In some cases, this has resulted in significant declines in property values, leaving residents with no financial means to escape oil and gas activity. It is important to note that many residents are given temporary financial incentives to allow fracking on their land. However, to some, the monetary compensation failed to make up for the toll fracking took on their physical and mental health. Lastly, some participants also mentioned feeling stress and anxiety from the social tension resulting from fracking. Debates about the restrictions and regulations on fracking have divided many communities, leading to conflicts and social tensions between once-amiable neighbors.
In addition to the interviews, an online survey was distributed to gain more insight as to where concerns about the changing physical landscape fell in relation to other effects associated with oil and gas development (such as poor air quality, water or soil contamination, truck traffic, and noise).
Nine individuals responded to the survey, all of whom indicated having oil and gas infrastructure within five miles of their home. All respondents also indicated that they participated in a wide variety of outdoor recreation activities such as hiking, wildlife viewing/photography, camping, hunting, and fishing.
Interestedly, only five respondents stated they felt fracking had a negative impact on their health, three responded they were unsure, and one responded no. However, all participants felt fracking had a negative impact on their surrounding environment. When discussing outdoor recreation, eight of nine respondents stated they felt fracking limited their access to outdoor recreation opportunities.
Next, respondents indicated that the level of concern related to the changing landscape brought about by fracking was equal to concerns about air pollution, water and soil contamination, noise, and truck traffic (using a 5-point likert scale). Lastly, one respondent stated that they closed their outdoor recreation tourism business due to blowdown emission (the release of gas from a pipeline to the atmosphere in order to relieve pressure in the pipe so that maintenance or testing can take place) and noise from fracking operations.
In summary, fracking operations have deeply impacted these individuals living in Washington County, Pennsylvania. Not only do residents experience deteriorating air quality, water contamination, and physical health effects, but the mental and emotional toll of witnessing multigenerational farms become forever changed can be overbearing. Other mental health impacts included rising social tensions, feelings of powerlessness, and continuous emotional distress. Fracking operations continue to change the physical landscape, tarnishing Southwest Pennsylvania’s natural beauty and threatening access to outdoor recreation opportunities. Unfortunately, those not living in the direct path of fracking operations struggle to grasp the severity of fracking’s impact on families living with oil and gas infrastructure on or near their property. More widespread awareness of fracking’s impacts is needed to educate communities and call for stricter enforcement of regulations for the oil and gas industry. As one resident summed up their experiences,
“Engines are running full blast, shining lights, and just spewing toxins out there. And you can’t get away from it. You just can’t. You can’t drink the water. You can’t breathe the air. You can’t farm the ground. And you’re stuck here.”
Hopefully, shedding light on residents’ experiences such as these will bring policymakers to reconsider fracking regulations to minimize the impact on public health and the surrounding environment.

As a spring 2020 intern with FracTracker, my work mostly involved mapping gathering lines in West Virginia and Ohio. Gathering lines are pipelines that transport oil and gas from the wellhead to either compressor stations or storage/processing facilities. The transmission pipelines (which are often larger in diameter than gathering lines) take the oil and gas from the processing facilities to other storage facilities/compressor stations, or to distribution pipelines which go to end users and consumers. As you can see from Figure 2 in the map of Doddridge County, WV, many gathering lines eventually converge at a compressor station. You can think of gathering lines like small brooks and streams that feed transmission pipelines. The transmission lines are the main arteries, like a river, moving larger quantities of gas and oil over longer distances.
The main project and goal of my internship was to record as many gathering pipelines as I could find in Ohio and West Virginia, since gathering lines are not generally mapped and therefore not easily available for the public to view. For example, the National Pipeline Mapping System’s public map viewer (created by the Department of Transportation Pipeline and Hazardous Materials Safety Administration) has a note stating, “It does not contain gas gathering or distribution pipelines.” Mapping gathering lines makes this data accessible to the public and will allow us to see the bigger picture when it comes to assessing the environmental impact of pipelines.
After collecting gathering line location data, I performed GIS analysis to determine the amount of acreage of land that has been clearcut due to gathering pipeline installations.
Another analysis we could perform using this data is to count the total number of waterways that the gathering lines cross/interact with and assess the quality of water and wildlife in areas with higher concentrations of gathering pipelines.
Figure 1. This map shows an overview of gathering line pipelines in the Powhatan Point, Ohio and Moundsville, West Virginia of the Ohio River Valley.
I worked with an aerial imagery BaseMap layer (a BaseMap is the bottommost layer when viewing a map), a county boundaries layer, production well location points, and compressor station location points. I then traced lines on the earth that appeared to be gathering lines by creating polygon shapefiles in the GIS application ArcMap.
My methodology and process of finding the actual routes of the gathering lines included examining locations at various map scale ranges to find emerging line patterns of barren land that connect different production well points on the map. I would either concentrate on looking for patterns along well pad location points and look for paths that may connect those points, or I would begin at the nearest gathering line I had recorded to try to find off-shoot paths off of those pipelines that may connect to a well pad, compressor station or previously recorded gathering line.
I did run into a few problems during my search for gathering lines. Sometimes, I would begin to trace a gathering line path, only to either loose the path entirely, or on further inspection, find that it was a power line path. Other times when using the aerial imagery basemap, the gathering line would flow into an aerial photo from a year prior to the pipeline installation and I would again lose the path. To work around these issues, I would first follow the gathering line trail to its end point before I started tracing the path. I would also view the path very closely in various scale ranges to ensure I wasn’t tracing a road, waterway, or powerline pathway.
In the three months that I was working on recording gathering pipeline paths in Ohio and West Virginia, I found approximately 29,103 acres (3,494 miles) of barren land clearcut by gathering pipelines. These total amounts are not exact since not all gathering lines can be confirmed. There are still more gathering lines to be recorded in both Ohio and West Virginia, but these figures give the reader an idea of the land disturbance caused by gathering lines, as shown in Figures 1 and 2.
In Ohio, I recorded approximately 10,083 acres (641 miles) with the average individual gathering pipeline taking up about 45 acres of land. With my gathering line data and data previously recorded by FracTracker, I found that there are 28,490 acres (1,690 miles) of land spanning 9 counties in southeastern Ohio that have been cleared and used by gathering lines.
For West Virginia, I was able to record approximately 19,020 acres (1,547 miles) of gathering lines, with the average gathering line taking up about 48 acres of space each. With previous data recorded in West Virginia by FracTracker, the total we have so far for the state is 22,897 acres (1,804 miles), although that is only accounting for the 9 counties in northern West Virginia that are recorded.
Figure 2. This aerial view map shows connecting gathering line pipelines that cover a small portion of Doddridge County, WV.
I was shocked to see how many gathering lines there are in these rural areas. Not only are they very prevalent in these less populated communities, but it was surprising to see how concentrated and close together they tend to be. When most people think of pipelines, they think of the big transmission pipeline paths that cross multiple states and are unaware of how much land that the infrastructure of these gathering pipelines also take up.
It was also very eye-opening to find that there are at least 29,000 acres of land in Ohio and West Virginia that were clearcut for the installation of gathering lines. It is even more shocking that these gathering pipelines are not being recorded or mapped and that this data is not publicly available from the National Pipeline Mapping System. While driving through these areas you may only see one or two pipelines briefly from your car, but by viewing the land from a bird’s eye perspective, you get a sense of the scale of this massive network. While the transmission pipeline arteries tend to be bigger, the veins of gathering lines displace a large amount of land as well.
I was also surprised by the sheer number of gathering lines I found that crossed waterways, rivers, and streams. During this project, it wasn’t unusual at all to follow a gathering line path that would cross water multiple times. In the future, I would be interested to look at the number of times these gathering pipelines cross paths with a stream or river, and the impact that this has on water quality and surrounding environment. I hope to continue to record gathering lines in Ohio and West Virginia, as well as Pennsylvania, so that we may learn more about this infrastructure and the impact it may have on the environment.
I first heard of FracTracker three years ago when I was volunteering with an environmental group called Keep Wayne Wild in Ohio. Since learning about FracTracker, I have been impressed with their eye-opening projects and their ability to make the gas and oil industry more transparent. A few years after first hearing about FracTracker, and as my interest in the GIS field continued to grow, I began taking GIS classes and reached out to them for this internship opportunity.

When driving through Pennsylvania, you can see what an impact oil and gas has had on the state. Towns like Oil City and Petrolia speak to the oil and gas industry’s long standing history here. In more recent history, Pennsylvania has been a prime fracking location because of the presence of the Marcellus shale formation that covers over half of the state. With more unconventional oil and gas exploration came impacts to communities, who were denied their right to “clean air, pure water, and the preservation of the natural, scenic, historic, and esthetic values of the environment” as defined by the Pennsylvania Constitution.
Hydraulically fractured wells are often no longer profitable after just one stimulation, after which they are abandoned. Improperly abandoned wells wreak havoc on our communities and our environment. The number of improperly abandoned wells has been increasing over time as companies go bankrupt transfer wells to other companies. These wells can easily go undetected because they are often buried underground, leaving no traces at the surface level.
These unplugged abandoned wells are underneath our homes, our schools, and in our own backyards, negatively impacting our health and the environment.
FracTracker’s West Coast Coordinator Kyle Ferrar shows how abandoned wells are hiding all around us in his investigation of downtown Los Angeles. He used an infrared camera to visualize the plumes of methane and other volatile organic compounds spewing out of abandoned wells in the middle of streets.
The plugging process consists of filling the well with cement, ensuring that nothing leaks from the well into the surrounding ecosystem. Without that measure in place, the chemical-water solution used to frack the underlying shale, as well as any oil or natural gas still left in the well, can very easily seep into nearby aquifers or into close by waterways. Wells that are not plugged or are not plugged properly leak into nearby aquifers, releasing methane and other volatile organic compounds are continually released from the well into the atmosphere as well. This leakage into the atmosphere and ground water can have disastrous effects on our ecosystem and health.
Abandoned wells are also a dangerous threat because many of their locations are unknown. These wells can ruin the structural integrity of buildings and homes that are unknowingly built on top of them. The methane leaking out of the well is colorless and odorless, meaning that it can easily build-up in homes or elsewhere and cause explosions.
When an oil and gas company drills a well, they are responsible for making sure that it is plugged properly at the end of the well’s life. This is the case even if the company goes bankrupt. To do this, Pennsylvania government requires that the company put up a bond that is set aside to plug the well properly. This ensures that if the company does go bankrupt, the necessary funds are already set aside to plug the well. Normally, this bond takes the shape of a blanket bond amount of $25,000 which is intended to cover the total expenses that would be incurred in plugging all of the wells a company has in the state. Depending on the number of wells a company possesses, this could mean very little actually being set aside for each individual well.
A shallow well can cost between $8,000 to $10,000 plus, and up to $50,000 or more depending on how difficult it is to plug. In the case of Pennsylvania’s top oil and gas holder Diversified Gas & Oil PLC and its recently acquired. Company Alliance Petroleum Corp, this bond sets aside just $2 per well. With most other companies holding no more than 5,700 wells, this sets aside $4.40 per well. Where the bond amounts fall short in accounting for the cost to plug the hundreds of thousands of abandoned wells across the state, the rest of the cost falls at the feet of taxpayers.
The state government has started to recognize the severity of the situation as they are confronted with a mountain of costs in plugging these wells. To start to mitigate this, the government has recently settled with Diversified Gas & Oil. The company has been ordered to properly plug 1,058 abandoned wells. To do this they have signed on to a $7 million bond with $20,000 to $30,000 bonds for each additional abandoned or non-producing well that is acquired.
Although it is a great start to ensure that these two major companies have the proper bonding amount moving forward, this does not apply to all companies, whose likelihood of going bankrupt puts a lot of financial pressure on Pennsylvanian citizens. Also, these 1,058 wells are only the tip of the iceberg, with the DEP estimating that there are between 100,000 and 560,000 total abandoned wells in Pennsylvania, many of which still have unknown locations.
In the 2017 Pennsylvania Oil and Gas Report, it is stated that: “Currently, more abandoned wells are being added to the state’s inventory than are being addressed through permanent plugging through state-issued contracts. Since 2015, DEP has been able to fund the plugging of oil and gas wells only in emergency situations and/or when residents must be temporarily evacuated from their homes due to imminent threats that legacy wells pose when well integrity is compromised.” They continue on by stating that, considering the historic operating costs and acknowledging the sheer number of wells, properly addressing es the abandoned wells will cost between $150 million and $3.7 billion. The $150 million is an estimation based on the scenario that no more historic legacy wells are discovered, and the $3.7 billion is based on if 200,000 more are found, a more likely scenario.
The funding to cover the costs of plugging these abandoned wells comes from surcharges of $150 and $200 established by the 1984 Oil and Gas Act for each oil well permit and gas well permit. The DEP has received fewer permits in recent years meaning that there are very little funds to resolve this issue. This means that eventually this public health and environmental burden will have to fall at the feet of the taxpayers.
This makes the state’s step in the right direction look more like a tip toe. With no real, substantial plans to locate and address the large amount of wells across the state, the government is putting their people at risk because these abandoned wells are not harmless.
Washington County can be used as a window into the abandoned well crisis in Pennsylvania. This county sits in the middle of the Marcellus Shale formation, making it a key site for unconventional oil and gas development. According to the DEP, there are 215 abandoned, orphaned wells in Washington county, but realistically we know that there are likely many more than that.
The Pennsylvania Spatial Data Access (PASDA) has derived a dataset from historical sources to determine the possible locations of other abandoned wells. These historical documents include the WPA, Ksheet, and Hsheet collections. This data set highlights over 6,000 locations where an abandoned oil and gas well could be located.

This is a testament to how many of these wells exist without our knowledge. If this difference in DEP records and possible wells is this great in Washington County, then we face the enormous potential problem of tens of thousands of additional abandoned wells that need to be resolved. The effects of these wells are real and they must be identified quickly.
These are some of the physical effects of abandoned wells:

Pennsylvania is facing a mountain of an issue with decades of work ahead. The state must act quickly to ensure the health and protection of our people and our environment, which entails taking active steps to secure an adequate budget to resolve this issue. To start, the state should identify where all of the wells are, set up a financial plan that puts the cost of the plugging process for these wells back onto the oil and gas companies, and begin to take active measures to plug the wells quickly and efficiently.

Sea otters, an endangered keystone species, are at risk due to offshore oil and gas drilling spills. Along the west coast of the U.S., this marine mammal’s habitat is commonly near offshore drilling sites, specifically in California and Alaska.
Sea otter numbers used to range from several hundred thousand to more than a million. Today, there are estimated to be just over 106,000 in existence worldwide, with fewer than 3,000 living in California. Their habitats range from Canada, Russia, Japan, California and Washington, but the majority of all wild sea otters are found in Alaskan waters.
Sea otters play a significant role in their local environments, and a much greater ecosystem role than any other species in their habitat area. Sea otters are predators, critical to maintaining the balance of the near-shore kelp ecosystems, and are referred to as keystone species. Without this balancing act, coastal kelp forests in California would be devoured by other aquatic life. Sea otter predation helps to ensure that the kelp community continues to provide cover and food for many of the marine animals. Additionally, kelp plays a tremendous role in capturing carbon in the coastal ecosystems. In that sense, sea otters also inadvertently help to reduce levels of atmospheric carbon dioxide.
Recently, Alaska and California, home to a wide variety of marine life, have been popular areas for offshore oil and gas drilling, which may include the use of fracking to extract hydrocarbons. Oil spills are a great concern for the sea otter; unlike other marine animals that may be able to eventually rid themselves of the oil, contact with the oil causes the sea otters fur to mat, preventing insulation, which can lead to hypothermia. Additionally, the ingestion of toxic oil chemicals while cleansing their fur can cause liver and kidney failure, as well as severe damage to their lungs and eyes.
Because their numbers are low and their geographic location area is rather small compared to other sea otter populations, the California sea otter is especially vulnerable, and could be devastated by oil contamination.

On March 24, 1989, the tanker vessel Exxon Valdez ran aground on Bligh Reef in Prince William Sound, Alaska, spilling an estimated 42 million liters of Prudhoe Bay crude oil. This incident affected marine life throughout western Prince William Sound, the Gulf of Alaska, and lower Cook Inlet. An estimated 3500–5500 otters from a total population of about 30,000 may have died as a direct result of the oil spill. Oiling and ingestion of oil-contaminated shellfish may have affected reproduction and caused a variety of long-term sublethal effects. Necropsies of sea otter carcasses indicated that most deaths of sea otters were attributed to the oil, and pathologic and histologic changes were associated with oil exposure in the lung, liver, and kidney. Studies of long-term effects indicate that the sea otter population in the Prince William Sound area suffered from chronic effects of oil exposure at least through 1991. While some populations may recover after a spill, it would seem that the threat of oil pollution impacts is intensified for populations in deteriorating habitats and to those that are in decline.

On Tuesday, May 19, 2015, a pipeline was found to be leaking into the Santa Barbara Coast in California. This broken pipeline, owned by Plains All American, spilled approximately 105,000 gallons of crude oil into the ocean, according to various news reports, stretching out into a 4-mile radius along the central California coastline.
These waters are home to an array of shore birds, seals, sea lions, otters and whales. Numerous amounts of marine life have been found washed up on the shore, including crabs, octopuses, fish, birds, and dolphins. Elephant seals, sea lions, and other marine wildlife have been taken to Seaworld in San Diego for treatment and recovery.
The Santa Barbara accident occurred on the same stretch of coastline as spill in 1969 that – at the time – was the largest ever incident in U.S. waters and contributed to the rise of the American environmental movement. Several hundred-thousand gallons spilled from a blowout on an oil platform, and thousands of seabirds were killed and numerous ocean wildlife, including sea lions, elephant seals, and fish perished.
Overall, the ocean is home to a great diversity of marine wildlife, all of which are vulnerable to oil contamination. Offshore gas drilling is a significant threat to the survival of sea otters and other marine life, wherein spills and accidents could cause health problems, toxicity, and even death. Oil spills are exceptionally problematic for sea otters, due to the vulnerable state of this animal and its endangered species state. Keeping keystone species healthy is instrumental to maintaining a well flourished ecosystem, while protecting habitats for a large array of marine and wildlife. The potential impacts on CA sea otters and other marine life due to events such as the 2015 oil spill in California should not be taken lightly.

Technologically-enhanced, naturally-occurring radioactive materials, also known as TENORM, are produced when radionuclides deep in the earth are brought to the surface by human activity such as oil and gas drilling. The radioactive materials, which include uranium (U), thorium (th), potassium-40 (K-40) and their decay products, occur naturally in the environment. These materials are known to dissolve in produced water, or brine, from the hydraulic fracturing process (e.g. fracking), can be found in drilling muds, and can accumulate in drilling equipment over time.
According to the EPA, ~30% of domestic oil and gas wells produce TENORM. Surveys have shown that 90% of the wells show some TENORM concentrations, while others have nothing at all. However, with increasing natural gas exploration and production in Pennsylvania’s Marcellus Shale, there is a parallel increase in TENORM. According to Dr. Marvin Resnikoff, an international expert on radiation, drilling companies and geologists locate the Marcellus Shale layer by way of its higher level of radiation.
Bringing more of this TENORM to the surface has the potential to greatly impact public health and the environment. Since 2013, the Pennsylvania Department of Environmental Protection (PA DEP) has been gathering raw data on TENORM associated with oil and gas activity in the state. The study was initiated due to the volume of waste containing high TENORM concentrations in the state’s landfills, something that is largely unregulated at the state and federal level. In January 2015, the PA DEP released a report that outlined their findings and conclusions, including potential exposures, TENORM disposal practices, and possible environmental impacts.
Drilling mud being collected on the well pad
This review touches on the samples tested, the findings, and the conclusions drawn after analysis. The main areas of concern included potential exposure to workers, members of the public, and the environment.
The samples gathered by the DEP came from 38 well sites, conventional and unconventional, by testing solids, liquids, ambient air, soils, and natural gas near oil and gas activity in Pennsylvania. All samples contained TENORM or were in some way impacted by TENORM due to oil and gas operations. The samples were mainly tested for radioactive isotopes, specifically radium, through radiological surveys.
The PA DEP concluded in the cases of well sites, wastewater treatment plants (POTW), centralized wastewater treatment plants, zero liquid discharge plants, landfills, natural gas in underground storage, natural gas fired power plants, compressor stations, natural gas processing plants, radon dosimetry (the calculation and assessment of the radiation dose received by the human body), and oil and gas brine-treated roads that there is little potential for internal radiation exposure to workers and members of the public. In spite of this, each section of the report typically concluded with: however, there is a potential for radiological environmental impacts…
Examples of these findings include:
According to Melody Fleck from Moshannon Group- Sierra Club Executive Committee:
While the report comprehensively covers the processes from drilling to end users, the number of samples collected and analyzed are very sparse for a state-wide study. Just to give an idea, only 8 well sites were sampled during the flowback phase and of the 8 only 4 had enough volume to analyze. Of 14 drill mud samples collected, only 5 were analyzed as liquids, and alpha & beta analysis was only done on one sample.
Obtaining the proper sample size is often a major barrier for field studies. Additional research needs to be conducted with a larger sample size and more rigorous exposure monitoring to determine specific risk metrics for workers and the public.
From drilling to distribution, there are many topics of concern associated with TENORM; however, we will focus on the current treatment of TENORM waste, the release of data, and the transparency of this issue.
On a federal level, there are no specific regulations governing many aspects of TENORM, such as sludge or solids containing TENORM from water treatment plants. Additionally, if concentrations of U or Th make up less than .05% by weight, they are seen as an “unimportant quantity” and are exempt from NRE regulation. Currently, 13 states regulate TENORM with varying degrees of standards. Hazardous waste facilities in each state can choose to accept TENORM materials as long as they don’t exceed certain concentrations.
Today, about 12 of PA’s 50 landfills accept such radioactive waste from oil and gas activity at a 1:50 dilution ratio (related to their other intake sources). Under RCRA’s Land Disposal Restrictions, “dilution is prohibited as treatment for both listed and characterized wastes.”
According to the DEP report, hydraulic fracturing produces an enormous stream of waste by-products. Safe disposal of this waste has not yet been devised. A few of the conclusions concerning TENORM disposal and treatment in the report listed some areas of concern, identified below:
In unison with the conclusions were recommendations, where the report “recommends considering limiting radioactive effluent discharge from landfills, and adding radium-226 and radium-228 to annual sample analysis of leachate from landfills.” Additionally, the report states that if something such as filter cake spills, it will bring into question the safety of long-term disposal and suggest a protocol revision.
The report identified two places where there is a higher than average radioactive exposure risk for workers and community members of the public: specifically at centralized wastewater treatment plants and zero liquid discharge plants that treat oil and gas wastewater. An additional unknown is whether there is a potential inhalation or ingestion hazard from fixed alpha and beta surface radioactivity if materials are disturbed. As a general precaution, they recommend the evaluation of worker’s use of protective equipment under certain circumstances.
Although research has not come to a consensus regarding a safe level of radiation exposure, it should not be assumed that any exposure is safe. Past research has evaluated two types of radiation exposure: stochastic and non-stochastic, both of which have their own risks and are known to be harmful to the human body. The EPA has defined stochastic effects as those associated with long-term, low level exposure to radiation, while non-stochastic effects are associated with short-term, high-level exposure. From past scientific research, radiation is known to cause cancer and alter DNA, causing genetic mutations that can occur from both stochastic and non-stochastic exposure. Radiation sickness is also common, which involves nausea, weakness, damage to the central nervous system, and diminished organ function. Exposure levels set by the EPA and other regulatory agencies fall at 100 millirem (mrem) per year to avoid acute health effects. As a point of reference, medical X-rays deliver less than 10 mrem, and yearly background exposure can be about 300 mrem.
In the report, Radiological Dose and Risk Assessment of Landfill Disposal of TENORM in North Dakota, Argonne National Laboratory researchers suggest that the exposure to workers be limited and monitored. In many of their studies, they found the doses exceed the 100 mrem/year level in the workers when the appropriate attire is not worn during working hours, which raised some concern.
The DEP deems certain radiation levels “allowable”, but it should be noted that allowable doses are set by federal agencies and may be arbitrary. Based on the PA DEP’s report, consumers of produced gas can get up to 17.8% of their yearly radiation allowance, while POTW workers could get up to 36.3% of their yearly allowable dose. According to the Nuclear Information and Resource Service, radiation bio-accumulates in ecosystems and in the body, which introduces a serious confounder in understanding the risk posed by a dose of 17.8% per year.
The DEP has been gathering data for their TENORM report since 2012. In July of 2014, Delaware Riverkeeper Network filed a Right-to Know request to obtain the information that the DEP had collected in order for their expert to analyze the raw data. The department refused to release the information, insisting that “the release of preliminary invalidated data, including sample locations, could likely result in a substantial and demonstrable risk of physical harm, pose a security risk and lead to erroneous and/or misleading characterizations of the levels and effects of the radioactive risks.” Essentially, the DEP was equating the risks of radioactive material to the risks of releasing raw data — two incomparable risks. DRN appealed, claiming that they simply sought the raw information, which is presumed public unless exempt, and would have no risk on the public. PA DEP was ordered to release their records to DRN within 30 days.
One observation that you could take from this report is the lack of regulatory advancement. The study is filled with suggestions, like:
Intent doesn’t make the changes; action does. Will any regulations change, at least in Pennsylvania where radioactive materials are returning to the surface on a daily basis? There seems to be no urgency when it comes to regulating TENORM and its many issues at the state level. Are workers, citizens, and the environment truly being protected or will we wait for a disaster to spur action?

When the unconventional oil and gas extraction boom hit Pennsylvania in the mid-2000s small, local operators were among the first on the scene. As shale plays continued to develop, many of these smaller companies were bought out by larger, national corporations. Larger oil and gas development companies often maintain that they are better able to handle the expected regulatory requirements, and so FracTracker wanted to determine if there was a change in the compliance record for wells that changed hands. Does having more resources available to them translate into stronger compliance standards for oil and gas drillers, better training for their employees, and a greater burden to get things right? Investigating these questions by looking into compliance data and the sale of wells, however, was no easy task.
There are no indications in either the drilled wells or permits datasets available from the DEP that a well has changed hands; in both of these sources, one operator’s name is simply substituted for the other. It is possible to comb through old news stories, and find that East Resources sold its assets to Shell in 2010, for example. However, this approach is piecemeal, and would not lead to satisfactory results on an industry-wide analysis.
Major obstacles to our analysis included:
Unlike wells and permits, any items on the compliance dataset are attributed to whichever company was operating the well at the time the violation was issued. So while FracTracker could not do the analysis that we wanted to because of the limitations of available data, we were able to isolate 30 wells that have changed hands between January 1, 2000 and November 4, 2014 (Table 1). One well has been bought and sold twice, with each of the three operators being issued violations.
In some instances the original well owner was reported to be out of compliance more times than the second owner. For example, API Number 013-20012 had 11 violations reported under its first owner and only 1 since it has been sold. The contrary also occurred, however, such as in the case of API Number 065-26481, which had 4 violations reported under its first owner and 14 under its second owner. There are not enough data points to determine which scenario is the trend in the data – if in fact there is one.
Due to limitations in the data, we cannot currently evaluate whether the notion that larger companies can improve the track record of problematic wells. In fact, many of the wells that were issued violations for multiple operators really just changed hands from one big operator who wanted to get out of the Marcellus to another big operator who wanted to get in. Our small sample doesn’t include any of the wells that were issued violations to only one company, of all the wells that changed hands over the years. To accurately assess the scenario, more data would have to be released, specifically the date when wells changed hands from one company to another.
