Are you comfortable with fracking in your backyard?

In Colorado, “backyard fracking” is more common than you might realize.

While incidents involving oil and gas operation are rare, they still occur, disastrous results can leave famlies devastated.

Our group was curious about how much the local population knew about fracking given its prevalence in Colorado. This interest grew when we researched a house in Firestone, Colorado that exploded.

We were also concerned about the negative health impacts and the importance of fracking in regards to the domestic natural gas and oil supply.

Fracking is a complicated topic, starting off we must first understand what exactly fracking is.

Interview with Prof. Ryan

We interviewed CU Professor Joseph Ryan of the Civil, Environmental, and Architectural Engineering department. He teaches classes like Environmental Organic Chemistry and Introduction to Environmental Engineering. He was a great candidate for our interview in this project, because of his background studying hydraulic fracturing and its impact on aquifers & groundwater systems in eastern Colorado. In our interview, Professor Ryan mentioned projects he has worked on supported by awards from the National Science Foundation. Ryan is knowledgeable about the local fracking industry, air and water pollutants, and the complex relationship between oil drilling and human development.

Fracking operations in Colorado

Colorado is typically 6th in Fossil Fuels production, with fracking being a major compontent of its fuels production.

Fracking operations in Colorado are heavily clustered within the boundaries of Weld County

Quoting Professor Ryan, "Weld County, by the way, has something like 25,000 active wells. More wells than any county in the United States"

Looking at this map, were you aware of how widespread Fracking is in Colorado?

Drilling Direction

A typical vertical well

The first and "traditional" form of fracking comes in vertical wells. These wells have been the preferred methood for fracking since its inception in the 1840s. Vertical wells were primarily used in Colorado up until 2010.

A concern of these wells are the age. Often times wells that are no longer profitable will be sealed and forgotten about. As they continue to age the question of how effective the seals were in the well comes into question. Often times we are finding that these old sealed wells are leaking gasses.

Horizontal drilling is a more effective use of fracking. The drill descends down thousands of feet until it intersects shale formations where oil and natural gasses are found. The drill then makes a turn and continues horizontally. This allows for hydrocarbons to be released from the rock and stored for later use. Following 2010, most of the drilling in Colorado was swapped from vertical to horizontal.

Case Studies

With an understanding of the basics of fracking and its extent in Colorado, we decided to undertake 2 case studies to expand our knowledge and highlight frackings real impact on Colorodans

One of our group members who grew up in the area mentioned a House in Firestone Colorado that exploded in 2017. This house was located next to an old fracking well and its associated pipeline.

Firestone

In 1993, a Vertical Well was approved for natural gas extraction. It was named “Coors V6-14Ji”, one of hundreds of wells drilled in an area of the Denver Basin known as the Watternberg Gas Field. It was just 170 feet south from the location of the home that exploded.

What Happened?

During the ensuing investigation, the utility service line to the home for domestic natural gas was found to have not been the cause: The line was tested, and held pressure with no leaks Pipelines that previously connected to the fracking well in question (Coors V6-14Ji) were found severed in proximity of 6312, Twilight Avenue’s foundation Excessive levels of natural gas were found in the soil during the excavation of rubble (high explosive risk) In 1999 when the well was abandoned, the lines were not disconnected from the reservoirs of fossil fuels they were connected to. This was a breach of regulations by Patina (the company that owned and operated the well at the time) that were in place Before construction began in 2015, Anadarko (the company that took ownership of the well) “shut in” Coors V6-14Ji and other wells in the area, sealing the drilled shaft (but not the pipes) The cause of the accident was determined to have been the severing of the pipelines connected to Coors V6-14Ji during the construction of 6312, Twilight Avenue, which caused the buildup of explosive natural gas in the soil around the home Residential building approvals were also found to be at fault due to allowing construction to begin on land in proximity to active/previous oil/gas production fields without comprehensive documentation about the wells from Anadarko

Mead

As seen in the images above, fracking sites and related activities (such as flaring) are close to neighborhoods in Mead, Weld County. In our interview with Professor Ryan, he mentioned that the EPA says operators are supposed to combust 95% of the waste gas, including greenhouse gases like methane and carbon dioxide. Since methane is more potent than CO2, operators burn off the methane. Flaring is performed because the gasses are burned off instead of simply being released into the air downwind from residential buildings.

Flaring itself has potential consequences, however; health impacts will be discussed next. As seen above, this Mead flaring/drilling site has horizontal drilling running directly underneath newly developed neighborhoods. In this situation, the drills were there before the neighborhood was developed.

Health Impacts

Backyard fracking is concerning because of its associated negative health impacts on human populations.

Health effects from humans proximity to fracking is primarily monitored through birth defects. Birth defects are monitored due to the fact that most are over a 9 month long period in one location. With cancer motioring often times people move around, and its timescale is much more variable.

Research in a fracking heavy region of texas shows an increase in four main birth defects. Professor Ryan reinforced the idea that negative health effects could result from fracking by alluding to the contamination of the air and water. Harmful chemicals named BTEX (Benzene, Toluene, Ethylbenzene, and Xylene) are monitored and often found in water samples near fracking sites. BTEX and other chemicals such as methane are responsible for the viral videos of people lighting their tap water on fire.

Setback Distances and Future Development

Given the potential health impacts of fracking on Coloradans, a key question arises: how close should fracking sites be to human development?

In our interview with Professor Ryan, we talked about this issue of setback distances and development going into the future. He provided us with some background information. Previously, sites were required to be just 150 feet away from development like neighborhoods, schools, and businesses. In most current Colorado situations, the distances are up around 2,000 or 2,500 feet.

All of us wondered if these distances are enough to protect people from air emissions, and Ryan reminded us that there is no scientific basis to say that 2,000 feet is safe or unsafe. A compromise exists between oil companies and state/local governments’ regulations. Ryan explained that with the development of horizontal drilling, setback distances do not necessarily hurt operators (although they may say they do). This is because operators can concentrate drilling on one pad that has a six mile wingspan extending horizontally, which can travel underneath neighborhoods thousands of feet beneath the surface.

Social Science Data: 6 America’s “Fracking” Survey

We created a distribution of how much the average person cares/knows about fracking, then place them within the 6 America’s distribution of alarmed to dismissive, the 4 questions asked were

What do you know about Fracking at our local level?

How much do you know about Fracking generally?

How much do you care about Fracking?

Would you let Fracking happen in your backyard?

Distribution of Results into 6 America's “Fracking”: Girl in a jacket

Results: Twenty-Five individuals were surveyed according to our 6 America's “Fracking”. Twenty-One students, One Professor, and Three individuals with no relationship to CU were surveyed. Most people do not know about Fracking nationally, nobody would allow fracking in their backyard, and those who did understand fracking did not know much at the local level.

Biases: Mostly CU students were surveyed, not representative of entire population knowledge. Confined to the four questions, does not show actual thought process.

Call to Action

Regulation before implementation

Aging infrastructure in conjunction with new development has lead to visual health issues

In Colorado, Fracking operations are intertwined with neighborhoods and development; the interactions between these two must be considered more

Results of survey: People do not understand fracking thoroughly but unanimously do not want it near them.
