Water and air pollution are the biggest risks to human health from fracking. [1] Research has determined that fracking negatively affects human health and drives climate change. [2] [3] [4] Fracking fluids include proppants and other substances, which include chemicals known to be toxic, as well as unknown chemicals that may be toxic. [5]
Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta , causing serious arsenic poisoning to large numbers of people.
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
A 2004 EPA study concluded that fracking injection in coalbed methane wells "posed little or no threat to drinking water;" the study has since been contraverted. [52] and some [who?] still contend that there is a lack of funded studies to show a large scale degree of fracking fluid polluted groundwater. Many oil and gas companies contend that ...
New Mexico, the No. 2 state for oil production behind Texas, is looking to its energy sector and water-intensive fracking as a potential sour New Mexico proposes regulations to reuse fracking ...
Those supporting federal regulation think it will provide a more consistent, uniform standard [186] as needed for national environment and public health standards, like those related to water and air pollution (e.g., public disclosure of chemicals used in hydraulic fracturing, protection of drinking water sources, and control of air pollutants).
In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (2% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]
