Although natural disasters are caused by nature and there is nothing that we can do to prevent them happening, there are many different natural causes that lead to natural disasters, and being aware of these causes enables us to be better prepared when such disasters do arrive. One common natural disaster is flooding, which occurs when a river bursts its banks and the water spills out onto the floodplain. This is far more likely to happen when there is a great deal of heavy rain, so during very wet periods, flood warnings are often put in place. There are other risk factors for flooding too:
Hide Waste water storage pond. Each well produces millions of gallons of toxic fluid containing not only the added chemicals, but other naturally occurring radioactive material, liquid hydrocarbons, brine water and heavy metals.
Fissures created by the fracking process can also create underground pathways for gases, chemicals and radioactive material. The Environmental Protection Agency EPA initially under an emergency administrative order forced three oil production companies operating on the Fort Human environmental hazards essay help Reservation, to reimburse the city of Poplar, MT for water infrastructure expenditures incurred as a result of drilling contamination.
The oil companies appealed the EPA order, but were forced to rectify their violations by a federal judge. Another scenario for contamination to occur is by faulty design or construction of the cement well casings--something that happened in the BP Gulf blowout disaster.
Storage of the waste water is currently under the regulatory jurisdiction of states, many of whom have weak to nonexistent policies protecting the environment. Soil and Oil Spill Contamination: The Associated Press also recently reported that the amount of chemically tainted soil from drilling waste increased nearly 5, percent over the past decade, to more thantons last year.
Steve Tillotson, assistant director of the North Dakota Health Department's waste management division, told reporters that trucks are hauling oilfield waste to facilities "24 hours a day, seven days a week.
In the aftermath of the spill, ExxonMobil has disclosed that the pipeline has been transporting tar sands oil from Alberta, Canada, which is a low grade, more toxic and corrosive type of oil.
Regulators had not been informed that the pipeline was carrying tar sands oil and the disclosure was a result of the spill. Tar sands oil was not in the pipeline at the time of the spill, though regulators are investigating whether or not it played a role in causing the pipeline to corrode.
Earthquakes Earthquakes constitute another problem associated with deep-well oil and gas drilling.
Scientists refer to the earthquakes caused by the injection of fracking wastewater underground as "induced seismic events. Health Effects of Fracking: A article in the journal, Human and Ecological Risk Assessment, examined the potential health impacts of oil and gas drilling in relation to the chemicals used during drilling, fracking, processing,and delivery of natural gas.
The paper compiled a list of chemicals an incomplete list due to trade secrecy exemptions identified from drilling operations throughout the U. Health impacts from fracking are only now being examined by health experts, since such large-scale drilling is a recent phenomenon.
Exposure to toxic chemicals even at low levels can cause tremendous harm to humans; the endocrine system is sensitive to chemical exposures measuring in parts-per-billions, or less. 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.
Despite the complexities of the on-site mixtures of chemicals and their specific contributions to health and environmental problems involved in fracking--conventional drilling practices are more old school and do have known health consequences.
Researchers at the Colorado School of Public Health, University of Coloradoanalyzed existing research of exposure to conventional petroleum hydrocarbons in occupational settings, and residences near refineries, in conjunction with known pollutants associated with fracking nonconventionalin order to assess health risks to those residents living near fracking operations.
Their basic conclusions were: Sounds obvious, but if you were to sue an oil company for the suspected killing a loved one via cancer, you would need a little more legal ammunition than "it just makes common sense" against an army of corporate lawyers.
Portier, PhD, has called for health studies to be published. A paper was published in the journal, Environmental Health Perspectives, examining the composition of state and federal advisory committees tasked to consider the potential environmental and health effects of fracking in the Marcellus shale region.
The researchers found that there was not one health expert among the 52 people comprising the various state and federal commissions and boards, even though public health was specified in the executive orders creating the committees.
Prevention or Mitigation While many state agencies function more as facilitators of fossil energy development than regulators, federal guardians of public health are also vulnerable to 'getting into bed' with big business, literally.
One need only recall the former federal agency in charge of collecting oil and gas royalties on public lands, the Minerals Management Service.
Employees from the Bush administration working for that regulatory agency were caught using cocaine and marijuana, and had sexual relations with oil and gas company representatives.
Many people concerned by nonconventional oil and gas drilling would prefer the US adopt the so-called precautionary principle, which places the burden of proof on industries implementing new technologies and introducing new chemicals into our neighborhoods and environment.
If your actions do not poison the water, accelerate climate change, cause cancer to those living near drilling and refineries, etc.OutlineThesis Statement: Advances in technology along with shifts in the nations’ social structure heavily impact the workplace environment, creating a need for new management models in Human Resources.

The four categories of human environmental hazards are cultural hazards, biological hazards, physical hazards and chemical hazards. Cultural hazards come from people that take risks and don’t think about the consequences until it’s too late.
The four categories of human environmental hazards are: Cultural hazard: This type of hazard is one that is a matter of choice or can be influenced by choice. Simply people engage in risky behavior of their own choice and subject themselves to different hazards they could avoid in the wanted to.
further highlights the merger of conceptualizations of human environment relationships with geographical techniques in understanding contemporary public policy r-bridal.com Words: haz- ards, vulnerability, geographic information systems, risk. Cancer prevention is action taken to lower the risk of getting cancer.
This can include maintaining a healthy lifestyle, avoiding exposure to known cancer-causing substances, and taking medicines or vaccines that can prevent cancer from developing.
