Effect on Environtment



Case Study

Veronica Kronvall from Ponder, Texas has a many wells surrounding her home; the closest two are 300ft from her property. When drilling for natural gas began she started experiencing frequent nosebleeds, nausea and headaches. Methane also contaminated their groundwater and the water in their sink can catch fire from holding up match. The problem was not solved because the Kronvall's did not own the mineral rights (underground) around their property so the area could be drilled.

Methane (CH4): the simplest alkaneFound in gas form underground and under the seafloor.The main component of natural gas which has energy stored in chemical bonds. Used for heating, cooking, generating electricity, and as fuel for vehicles.

Methane is carried into the stratosphere by rising air in the tropics. Methane is a potent greenhouse gas that when in the atmosphere for 100 years, it traps 29 times more heat per mass unit than carbon dioxide and 32 times more when interactions with aerosols are accounted for. This property of methane contributes to global climate change.

How humans are exposed to methane?

Humans can be exposed to methan when using it for cooking, heating, electricity, and fuel. Also if they live nearby natural gas drilling wells they are exposed in the air and sometimes in their groundwater.

Effect on Human Health

Short term: a person may feel tired, dizzy, and have a headache, depression, agitation and eventual loss of consciousness in both humans and animalsLong term: convulsions and death.

Gov't Involvment

EPA proposes air rules for the oil and gas industry (Amendments to the National Emissions Standards for Hazardous Air Pollutants for the Oil and Natural Gas Industry): July 28, 2011 - The U.S. Environmental Protection Agency proposed a suite of highly cost-effective standards to reduce emissions of smog-forming volatile organic compounds (VOCs) and air toxics from the oil and natural gas industry. The rules also would significantly reduce methane, a potent greenhouse gas.
