The Cadron Creek watershed covers approximately 775 square miles and is composed mostly of forests (48%) and grassland (37%). However, a pending permit, AR0052086C, would allow a centralized waste treatment facility to discharge, recycled fracking fluid waste waters into an unnamed tributary located within the Cadron Creek watershed. This unnamed tributary flows directly into Linn Creek, which would then feed into the north fork of the Cadron and eventually into the Arkansas river (ADEQ 2013). The Cadron Creek, located within the Arkansas river basin, is listed by the US Army Corps of Engineers as an extraordinary resource water body or ERWB (USACE 2013). ERWBs are important, because they satisfy a broad range of socio-economic, cultural, and environmental values which benefit both humans and the environment. ERWBs can help facilitate re-entry into nature, because of their scenic beauty, recreation potential, and their ecological and scientific values which can provide educational opportunities for the public. For this project, a suite of water quality metrics were collected from confluences and bridge crossings of headwater streams located within the Cadron Creek watershed. These water quality metrics included dissolved oxygen, pH, temperature and specific conductivity.
4. Literature Review:
Headwater streams are the peripheral reaches of larger river networks that make up between 50-70% of total reach length within the United States (Fritz et. al 2008). Headwater streams are a major component of river networks and are composed of small swales, creeks, and streams, which form the building blocks for large river and lakes. Headwater streams are very influential on the overall health of aquatic ecosystems, because they provide n...

...ydraulic fracturing. During Hydraulic fracturing, or fracking, holes are drilled into shale rock formations, deep beneath the earth's surface and injected with more than a million gallons of pressurized fracking fluid. This process creates small fissures within the rock layers that are held open by the sand particles, allowing the natural gas to vacate from the well (10). However, there is much debate over the long-term vitality and validity of the use of unconventional gas as a solution to the United States dependency on foreign oil. Much of this debate stems from what some have coined as the "exploration treadmill", the rate at which new plays must be added to production, in order to maintain a flat line and or growing (carbon)
The fracking fluid itself is mostly composed of water, sand, and small trace amounts of other chemicals, such as petroleum distillates.
Most of the rivers are the one being used by large communities like drinking water supply and for the farmers in their produce. The State of Department put together a commission of knowledgeable people and carried out an investigation about the risk and consequences of this project. Some of the conclusion about the spills were, for example, that: “A million of gallons of tar soil war poured into the Kalamazoo River in Michigan… 40 miles of this river still are contaminated to this day”. Another example of spills affecting communities, is the one in 2013, caused by a twenty foot crack in a pipeline, causing a huge spill of oil, damaging the residential neighborhoods and the Lake Conway in Arkansas. This spills and oil “accidents” are affecting not only the lives of people but also the wildlife, the ecosystems and the quality of air and water
In today's global economy, energy is one of the most crucial and sought after commodities. Who supplies it and how much they supply determines how much influence they have over other countries as well as the global economy. This is why hydraulic fracturing is currently such an important and controversial topic in the United States. Hydraulic fracturing, more commonly known as "fracking" or hydrofracturing, is the process of using pressurized liquids to fracture rocks and release hydrocarbons such as shale gas, which burns more efficiently than coal. This booming process of energy production provides a much needed economic boost, creating jobs and providing gas energy for Americans.
The United States has an immense amount of proven natural gas reserves that could become a major source for the nation's energy future (1). The mining of the natural gas resources have become feasible and cheaper due to the advancement of hydraulic fracturing technologies which have increased the amount the extraction and enabled “greater access to gas in shale formations” (2). Hydraulic fracturing, or fracking of shale formations has positive benefits that includes economic growth and the natural gas extracted is cleaner than coal and oil, however it has caused serious environmental problems and possibly could be the cause of recent seismic activity in areas where fracking operations exist (3).
The American Great Lakes; Superior, Michigan, Huron, Erie and Ontario make up 21% of the world’s surface, fresh water. These lakes are home to a variety of wildlife species and fish that are a concern. The lakes also provide drinking water for 40 million people. Commercial fishing, sport fishing and Native American fishing are the major industries providing jobs in the Great Lakes Region and this impacts the fragile ecosystem. The urban runoff and sprawl, sewage disposal, agriculture and toxic industrial waste also affect human health, fish populations, and aquatic food chains. The Great Lakes Restoration initiative is the largest investment in the Great Lakes in two decades. There is a task force of 11 federal agencies that developed an action plan to implement the initiative. The action plan is to cover fiscal years 2010-2014 and addressed five urgent issues. Those issues include; 1. Cleaning up toxics and areas of concern. 2. Combating invasive species, 3. Promoting nearshore health by protecting watersheds from polluted runoff, 4. Restoring wetlands and other habitats. 5. Tracking progress and working with strategic partners. In 2012 and 2013 with the input of citizens 3 key priorities helped to guide the restoration project. They were cleaning up areas of concern, reducing nutrients entering the lakes and preventing the introduction of new, invasive species. New technologies, such as a swimming video camera and an all-terrain robot, are granting researchers their first glimpse of a region critical to the Great Lakes’ health.
There are many causes and solutions to the deterioration of the Colorado River. The Colorado River is not the great river it used to be, with an abundant amount of healthy water, thriving wildlife and abundant plant life. With climate change, water salinity, pollution, and natural runoffs, the river’s water quality has deteriorated immensely. However, if communities and environmental groups join forces to research and raise money to find ways to help improve the Colorado River, it can get back to its original condition. This issues affects those who live by the river, concluding that I live somewhere near the river, I would love to see a change in the rivers condition to not only help the nature around it, but to help myself and others.
EnergyFromShale.org shows the fluid mixture is comprised of 90% water, 9.5% propping agents such as sand, and 0.5% chemical additives. Some of the chemicals found in this mixture are: sodium chloride, ethylene glycol, borate salts, sodium carbonate, guar gum, and isopropanol. Proponents of fracking will lead you to believe that the chemicals used are essentially harmless, and found in such small amounts as to have negligible side effects. On the CDC website, ethylene glycol is described as an odorless liquid with a sweet taste. When ingested it breaks down into toxic compounds. A person’s central nervous system, heart, and kidneys are affected. Large amounts of ethylene glycol can be deadly. While many say that the 0.5% amount of chemicals used is such a small amount, they are traceable amounts. Additionally, drilling companies are supposed to treat the fracking fluid before it is injected into the ground, left to dissipate, or released into surface water. The EPA claims that flowback is properly treated before it is disposed of, and that it is regulated by the National Pollutant Discharge Elimination System. After treatment, the EPA Underground Injection Control program is supposed to regulate the flowback being injected underground to dispose of it (epa.gov.,
Before one can see the devastating effects of fracking, one must first understand how fracking works. As previously stated, the main intent of hydro-fracking is to access and harvest natural gas that lies below the surface of the Earth. Having formed over 400 million years ago by the collision of tectonic plates (Marsa 3), the Marcellus Shale plays host to a gold mine of natural gas, which is currently at the center of the fracking debate in the Northeastern region of the United States. Unfortunately, access...
For those of you who do not know what fracking is exactly, it is when water is mixed with sand and chemicals, and then is injected into wells at hi...
The process of fracking is very simple. Around 800 gallons of water is used as the base of what is called fracking fluid. Along with this, sand and 600 toxic chemicals are used to create the fluid. The fluid is then transported from a manufacturing plant to the site. It is then injected at high pressures into the ground through dilled pipelines. The fluid contains chemicals that keep these pipes from rusting over time. The fluid then reaches a well where it causes the nearby shale rock to fracture. This releases any trapped fuel in the rocks. Gravity and pressure is then used to force the fluid out of the pipes back to the surface. The fluid is then taken and left it large holes to evaporate. This causes release of chemicals and also leakage into ground water (Dangers of Fracking).
Then rupture the layer of sediment with high pressures of water, sand and a plethora of chemicals. Once the chemicals are saturated in the crevices of the drill site, they extract the excess fluid and then ship them to market. The process of hydrofracking allows for a new source of renewable energy, but it takes a toll on the environment. Five-hundred plus of toxic chemicals like hydrochloric acid, sodium chloride and formic acid are left in the ground.
Fracking is a highly controversial practice that utilizes the injection of water, chemicals and abrasives to extract relatively inaccessible pockets of natural resources. Although fracking has the potential to benefit the economy, it may also pose a significant impact on the environment, the ecosystem and safety.
Fracking is a pressurized, chemically treated mixture of water and sand to release and extract natural gas and petroleum from shale rock. There are many articles, studies being done, and organizations fighting for what they think is right. Environmentalist want the technique of fracking banned because it plays a part in global warming, affects our water, and causes human health problems. If fracking cannot be banned because of its necessity then it should be made safe and eco-friendly. The process involves a well being drilled vertically to the desired depth, then turns ninety degrees and continues horizontally for thousands of feet into the shale believed to contain the trapped natural gas. A mix of water, sand, and various chemicals is pumped into the well at high pressure in order to create fissures in the shale through which the gas can escape. Natural gas escapes through the fissures and is drawn back up the well to the surface, where it is processed, refined, and shipped to market. Flowback returns to the surface after the
Forest management can have either detrimental or positive effects on watershed supply and quality. The type of effect depends on the type of operation(eg. harvesting vs. reforestation), the way it is conducted, and the view point of the land manager(eg. more or less water yield).
