    This causes illness and deaths from air pollution, including nitrous oxides and particulates, and is a significant cause of climate change through emission of carbon dioxide. [3] [4] Within the transport sector, road transport is the largest contributor to climate change. [3]

  4. Urban runoff - Wikipedia

    en.wikipedia.org/wiki/Urban_runoff

    After heavy rainfall events that cause stormwater overflows, contaminated water can impact waterways in which people recreate or fish, causing the beaches or water-based activities to be closed. This is because the runoff has likely caused a spike in harmful bacterial growth or inorganic chemical pollution in the water.

    In some areas, especially along the U.S. coast, polluted runoff from roads and highways may be the largest source of water pollution.

    In road and rail transport, a washout is the result of a natural disaster where the roadbed is eroded away by flowing water, usually as the result of a flood. [1] When a washout destroys a railroad's right-of-way , the track is sometimes left suspended in midair across the newly formed gap, or it dips down into a ditch.

  9. Nonpoint source pollution - Wikipedia

    en.wikipedia.org/wiki/Nonpoint_source_pollution

    These bacteria are a commonly used indicator of water pollution, but not an actual cause of disease. [16] Pathogens may contaminate runoff due to poorly managed livestock operations, faulty septic systems, improper handling of pet waste, the over application of human sewage sludge, contaminated storm sewers, and sanitary sewer overflows.
