Gas, Oil, and other Hydrocarbons
- Are organic compounds that are made up of carbon-hydrogen
- Have a wide variety of structures and functions, some of
which can be considered pollutants of concern
- Can be petroleum hydrocarbon pollutants such as gasoline,
oils, and grease
- Can be Polycyclic Aromatic Hydrocarbons (PAHs) which are
formed by burning coal, gasoline and fuel oil
Why should I care?
Some hydrocarbon pollutants, such as PAHs, can result in negative health
impacts to humans and wildlife.
How do hydrocarbon pollutants enter our lakes and streams?
Potential sources for hydrocarbon pollutants include:
- Vehicle use and maintenance (brake lining)
- Disposal of used oil and other fluids on the ground
- Spills of oil or gasoline from vehicles
- Leaks of oil and other fluids from vehicles
- Runoff from residential car washing
- Vehicle exhaust
- Leaching from coal-tar sealants used on pavement
Most petroleum hydrocarbon pollutants are transported by
which washes the contaminants from roads, driveways, and parking lots into
the nearest storm drain or stream. However, some of these pollutants also
enter the water via motorized watercraft.
