Transcript of Water Pollution
the contamination of any body of water, big or small, by substances harmful to living things.
Long Term Impacts
Aquatic organisms are affected by the reduced amount of dissolved oxygen
The most common types of pathogens are associated with human and animal waste.
Eggs and larvae of aquatic creatures get destroyed by temperature changes.
Toxic substances like detergents and mercury salts cause harmful effects on water bodies.
Cyanide in water causes nerve damage and thyroid problems.
Causes to Water Pollution
Water runoff carrying fertilizing chemicals
We need and rely on clean water to survive, yet right now we are heading towards a water crisis.
It can kill large amounts of fish, birds, and other animals.
People can become ill and have serious health affects.
It can speed up the growth of algae, and deplete the oxygen supply
Makes streams, lakes, and coastal waters unpleasant to look at, to smell, and to swim in.
Intentional or Accidental?
Erosion is a natural cause.
Water runoff is both a human and natural cause.
Both erosion and water runoff is not intentional.
Population Growth Affects
As the population increases, more trash is being distributed into bodies of water
Chemical and radioactive water pollutants are correlated with the large population increase
The impact of population on the ability of water sources is paralleled by the effects of population on the quality of water resources
The inability to supply clean drinking water is due to overcrowding and a large percentage of the human population in 2010
Water used in households becomes contaminated by various chemicals.
Drainage from water applied in farming carries away chemicals on plants.
Industries introduce chemicals needed for the manufacture of their products.

throw away chemicals safely and correctly
clean up public areas
People would be for the solutions because...
finite amount of water
More than 97% of Earth's waters is saltwater, the remaining 2.5 percent is freshwater
Water is essential to survival
Some people might be against the solution because:
It could be expensive and difficult to remove the pollutants
It's either we use plastic or trees
The Clean Water Act:
Enacted in 1984
Regulates the release of pollutants into the waters of the United States\
Regulates quality standards for surface waters
Makes it unlawful to release any pollutant from a point source into waters, unless a permit was obtained
Enacted in 1974
Regulates the nation's public drinking water supply
Requires many actions to protect drinking water and its sources
Sets national health-based standards for drinking water to protect against both natural and man-made contaminants
Safe Drinking Water Act
Water Pollution Bill
To regulate the amount of pesticides that farmers use.
