    The Clean Water Act is to regulate discharges of pollutants into the waters of the United States and also regulate quality standards for surface waters. This act was created after the realization of the water pollution in the waters where the Cuyahoga River fires occurred. This act has been very effective because we now have many sources of clean drinking water to bottle. Also, since bodies of water are monitored, we know how healthy and clean it is at all times.

  • The Clean Air Act

    The Clean Air Act is designed to regulate emission of pollutants that could harm human health and welfare. This act was created because air pollution was effecting people so severely, that many deaths were the result of it. For example, in 1952, "killer smog" killed 3,000 people because of the air pollution in London. This act has helped the environment by cuttting ground level ozone smog by 25%, reduce mercury emissions, reduce the lead content in gasoline, and more.
  • Wilderness Act

    The Wilderness act also lead to the National Wilderness Preservation System that protects almost 110 million acres of wilderness areas from coast to coast. It was created to protect wildlife and also plant life. This is effective because in these areas, it is illegal to hunt, so wildlife is preserved. Also, it's protected where trees can't be cut down and for sets can't be wiped out. The nature of these areas is preserved and guaranteed to stay safe.
  • Cuyahoga River burning

    Also burned in 1868, 1912, 1936, and 1952.
    The Cuyahoga River first was set on fire by a passing train. The train created sparks which lit the oil-soaked debris floating in the waters surface. After realizing how much the water was polluted and how it could become a health risk for people, the Clean Water Act was passed. Since then, bodies of water are much cleaner and a less of a risk to human and environmental health.

This lead to illnesses of the people around the canal. Illnesses included epilepsy, asthma, migraines, and nephrosis. Also, abnormally high rates of birth defects and miscarriages in the neighborhood occured.
  • TMI nuclear accident

    TMI nuclear accident
    This accident started because there were failures in the non-nuclear secondary system. This was followed by a stuck-open pilot operated relief valve in the primary system. This let big amounts of nuclear reactor coolant to escape. The whole thing was caused by employee/human error and lack of training to recognize the situation. As a result of this accident, unknown amounts of radioactive gases and radio avid iodine was released into the environment.
  • Superfund

    Superfund was created to have specific people be responsible for cleaning up the nation's contaminated land and responding to oil spills, natural disasters, and other environmental emergencies. It was created to make sure people can live and work in a place where it is a healthy environment. This is effective because they help the environment when it can't help itself. They help it get back to a healthy and stable place so it's healthy for humans to be near, in, or around that particular area.
