NPS pollution, unlike pollution from industrial and sewage treatment plants (point sources), comes from many widespread sources and can be generated by most land use activities.
NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters, and even our underground sources of drinking water.
Common NPS pollutants include sediment, nutrients, heavy metals, pesticides, pathogens, pharmaceuticals, oil and salt
Point Source Pollution
Contaminants that enter a______________ body that can be ___________ back to a specific _________, location, and
____________________.
*Point source pollution is easier to manage compared to nonpoint source pollution.
Examples of point source pollution include:
~dumping of _________________ waste, sewage ___________________ facilities, hazardous chemical deposition (e.g. nuclear waste).
~Heat can also be a pollutant; power plants often use water to cool overheating components. Once used, this hot water is released into nearby lakes where it alters the lake’s temperature. This heat is a form of pollution because it can be harmful and kill aquatic life including sensitive fish species. Another example of widespread pollution is the legal discharge of sewage and other chemicals.
Thermal Pollution
~Nuclear power plants and coal powered steam plants use water to cool the _______________________. This heated water is then returned to the environment.
~__________________ power plants also produce radioactive materials that must be disposed of properly.
~________ powered plants produce waste products (i.e. fly ash) and air pollution (acid rain)
Algal Bloom
~______________ bloom results when excessive nutrients are in the water. Nutrients may include fertilizer, nitrates, phosphates, manure, etc.
~As algae dies, _______________ that decomposes the algae uses up dissolved oxygen in the water.
An algal bloom is a rapid increase in the population of algae (typically microscopic) in an aquatic system. Algal blooms may occur in freshwater as well as marine environments.
