There are so many sources of water pollution. One kind of source is a non-point source of pollution. A non-point source of pollution is water that runs off construction sites and farmland, different kinds of soil particles and nutrient that goes into streams and lakes. They also include water from things like lawns and gardens that sometimes carries fertilizer, insecticide, water from the roads and parking lots that carries things like salt, oil, and grease. These sources are (1) industrial wastes, (2) sewage, and (3) agricultural chemicals. Another type of source is municipal. The municipal source of water pollution consists wastewater from home and commercial establishments. For years the main goal of treating municipal wastewater was simply to reduce its content of suspended solids, oxygen-demanding materials, dissolved inorganic compound, and harmful bacteria. The basic methods of dealing with municipal wastewater falls into three stages: primary treatment, including grit removal, screening, grinding, and sedimentation. Now you know about the sources of water pollution.
Causes of Water Pollution
There are many causes of water pollution but two categories exist: direct and indirect. Natural and unknown causes of pollutants can impact water quality and it may be related to some of the human activities. The major causes of pollution in surface water in the state of Texas are elevated concentrations of dissolved solids, salinity, or sulfates. Many causes of pollution including sewage and fertilizers contain nutrients such as nitrates and phosphates. These types of organismís clogs our water way, use up dissolved oxygen as it decomposes, and block the light to deeper waters. This proves very harmful things to aquatic as it effects the respiration ability or fish and other things that reside in water. Now you know about the causes of water pollution.
Effects of Water Pollution
The effects of water pollution include poisonous drinking water, poisonous food animals, unbalanced river and lake ecosystems that can no longer support full biological diversity, deforestation from acid rain, and lots of other effects. Water pollution can also affect rain, rivers, lakes, oceans, and the water beneath the surface of earth called ground water. The effects of water pollution varied by lots of things.
Help Stop Water Pollution
You can help try to stop water pollution by making sure that no one throws any thing in the water. Another way you can help is by not trashing the land by the polluted water because when the water rises up it will take all the garbage by the shore and more pollution will come to the water. Now you know how you can help stop pollution.
Pollution affects the animals because when little microscopic animals called zooplankton eat the algae, and the fish eat the zooplankton, the fish produce body wastes and they eventually die. Another reason why water pollution can effect the animals is because when all the chemicals come into the polluted water the fish have to eat the plants and it may have chemicals on it. Eventually the fish ends up getting sick from the chemicals and die.
