The issue of fracking for the environment and human health

We are collecting data and information related to the extent to which CWT facilities accept such wastewater, available treatment technologies and their associated costsdischarge characteristics, financial characteristics of CWT facilities, the environmental impacts of discharges from CWT facilities, and other relevant information.

Storage of the waste water is currently under the regulatory jurisdiction of states, many of whom have weak to nonexistent policies protecting the environment. Despite precautions by industry, contamination may sometimes occur through corroded well casings, spilled fracturing fluid at a drilling site, leaked wastewater, or, more controversially, the direct movement of methane or water upwards from deep underground….

While most of them are common and generally harmless, some chemicals are carcinogenic. Further research is needed to identify both carcinogenic potential of chemicals used in hydraulic fracturing and their cancer risk.

Interpretative modeling shows that advective transport could require up to tens of thousands of years to move contaminants to the surface, but also that fracking the shale could reduce that transport time to tens or hundreds of years. No injuries or serious damage from the earthquakes has been reported.

The majority of water samples collected from sites in a drilling-dense region of Colorado exhibited more estrogenic, antiestrogenic, or antiandrogenic activities than reference sites with limited nearby drilling operations. Researchers were able to compile a list of chemicals, though this list is incomplete due to trade secret ememptions given to the energy companies by Congressional allies.

Environmental impact of hydraulic fracturing

Ingraffea said unconventional oil and gas development as a whole, rather than hydraulic fracturing specifically, is responsible for many environmental problems. Our data suggest that natural gas drilling operations may result in elevated endocrine-disrupting chemical activity in surface and ground water.

One example from the report states that the truck traffic to just one well site causes as much damage to roads as 3. The technique requires drilling down through hundreds of feet of rock and then horizontally through shale beds.

Fracking, shale gas and health effects: Research roundup

This reduction would be accomplished primarily through capturing natural gas that escapes into the air, and making it available for sale. A Journal of Environmental and Occupational Health, 22 1: The overall increase was tied to earthquake increases in a few specific areas: The earthquake occurred near two hydraulic fracturing wastewater injection wells that are reportedly close to capacity.

Osborn, Avner Vengosh, Nathaniel R. Underground injection related to hydraulic fracturing was exempted from the Clean Water Act, except if it uses diesel fuel. There is substantial geologic evidence that natural vertical flow drives contaminants, mostly brine, to near the surface from deep evaporite sources.

Several times, associations between hydraulic fracturing, causes of spills, and response to spills were unknown or indeterminate because of missing or unreported data.

OSHA has also raised concerns about the long-term respiratory effects of occupational exposure to airborne silica at fracking sites. Nevertheless, many of the health risks from the toxins used during the fracking process do not express themselves immediately, and require studies looking into long-term health effects.

Their basic conclusions were: In addition to water savings, gas fracturing reportedly produces less damage to rock formations that can impede production. The facility denied processing Marcellus waste since Flaring of natural gas should be more strictly regulated.

This report was cited in the full hydraulic fracturing water report now open for peer review [19] though not directly addressed in the contents of the EPA spill data report.

Human and Ecological Risk Assessment: Results of biomonitoring testing in the UOGD setting are often misleading for several reasons: Sincehe has been a freelance writer, contributing Philadelphia-area news to The New York Times; covering economics for Market News, and writing stories on the environment and other subjects for a number of local outlets including StateImpact.

For example, the health effects of breathing air or drinking water are researched in specific locations where there may be cause for concern.

Fracking ~ Environmental Issues

Hide Waste water storage pond. Water samples were collected, solid-phase extracted, and measured for estrogen and androgen receptor activities using reporter gene assays in human cell lines.

Agency for Toxic Substances and Disease Registry collected air samples at 14 sites, including 8 oil and gas sites, 4 urban background sites, and 2 rural background sites. In there were earthquakes in the same area, a sixfold increase over 20th century levels.

They recommended increased seismic monitoring near fluid injection sites to determine which areas are vulnerable to remote triggering and when injection activity should be ceased.Do you think your health may be affected by nearby unconventional oil and gas development (UOGD or “fracking”)?

If you have any concerns about your environmental conditions, be sure to let your health care provider know or contact EHP for help. Hydraulic fracturing, generally called ‘fracking”, is an efficient process for recovering natural gas from rock deep underground. Natural gas is cleaner-burning than coal or oil, so it can be better for the environment than those other fossil fuels.

In Pennsylvania, fracking companies violate rules and regulations meant to protect the environment and human health on virtually a daily basis. Between January 1,and September 30,fracking companies together committed a combined total of 4, violations, or an average of violations per day.

Fracking is dirty and dangerous. From the very beginning of clearing a site for drilling, through the extraction, transport and delivery of natural gas, fracking poses significant risks to our air and water and to human health. EPA works with states and other key stakeholders, through sound scientific research and regulation; to help ensure that natural gas extraction from shale formations, also called fracking or hydrofracking, does not harm public health and the environment.

Environmental impact of hydraulic fracturing in the United States has been an issue of public concern, increased seismicity and associated effects on human and ecosystem health. Science of the Total Environment. 79–
