While air pollution is created by volatile chemicals that vaporize during the gas filling process, soil contamination can result from underground pipes or tanks rusting or leaking, slowly releasing contaminants to the surrounding area. The constant spilling of gasoline can also cause significant pollution. Many gas stations are also service stations. In addition to filtering liquid from spilled gas, antifreeze, and oil, mechanics use other potentially hazardous materials.
Copper and brass are found in engine degreasers, and lead, oil, and grease can drip when radiators are washed. Working on the brakes can release asbestos. These pollutants often end up in storm drains, where they are carried to waterways. To avoid contamination, service stations must be kept dry with washing or rainwater.
In addition, any waste material must be recycled or stored until removed by a disposal service. Gasoline is a toxic and highly flammable liquid. The vapors that are released when gasoline evaporates and the substances that are produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulates, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.
The test results will depend on the environmental regulations of your state, city, or town, and the degree of compliance of gas stations. Newer gas stations shouldn't have any effect on the ground, but older gas stations can have an effect. A compound that contaminates soil and water near gas stations has been found to be called MTBE, or tert-butyl methyl ether. Hypothesize whether or not the presence of gas stations in your area affects the soil by observing plant life.
The common pollutants that gas stations release to the environment are represented by stored and sold petroleum products, such as gasoline and diesel fuel. While state and federal regulations limit some of the pollution, hazardous materials can still get from a gas station into the environment. Briefly presented below are the main and sometimes serious pollution problems associated with gas stations, along with the consequent pollution risks to health, the environment and the home.
