The hydrologic cycle is also known as the water cycle. This cycle controls the exchange between the atmospheres, bodies of water, and between lands. In the urban areas, the landscapes cause the water to pour off more quickly. When the water runs off the pavements and compacted soils, this can cause flooding. This will result in more infrastructures and waterways that were supposed to be natural are now used to drain off the run off water.
The particular classifications of contamination and sullying are microbiological, eutrophication, compound, suspended solids, strong squanders, warm, radionuclides, and spills. Microbiological squander for the most part comprise of the waste , material discovered I therapeutic waste. Despite the fact that there are particular directions for discarding this waste material, the contamination comes to fruition when those guideline are not being permitted. ("Water: Laws and Executive Orders," 2010). Eutrophication is an extreme wealth of supplements in a lake or different waterways.
This is known as nonpoint-source pollution. (Adapted from: www.explainthatstuff.com) Water pollution is happening everywhere but this investigation is focused on water pollution in Ga-kgapane and how the increase in population has led to an increase in this pollution. One of the main causes for water pollution in this town is: • The disposal of waste products in the streams • The washing of clothes and other things in these streams • Human activities such as swimming and playing in these streams Water pollution has become a growing problem in this town and has led to a lot of other issues that should be
Atmospheric pollution is caused by pollutants such as smoke from factories entering the atmosphere and being carried to waterways. Industrial waste can also create polluted runoff that collects in rivers and lakes. Another reason for water pollution is chemically treated sewage. This water carries harmful chemicals and high amounts of bacteria, which can potentially lead to serious diseases. Runoff from fields can contain chemical fertilizers and pesticides which can pollute
Unfortunately our oceans are suffering from many types of pollutants that are prominent in our environment. One of the main distributors of pollution is sewage. Sewage and other polluting substances flow into the world's rivers and drainage pipes until all of the substances dump out into the ocean. In addition to sewage, other chemicals finds its way to the oceans, which leads to the reduction of oxygen being released into the atmosphere. With this in place, the waters become murky and filled with substances that can harm marine life.
Even though the manatee deaths were not determined many believe that itś the oil spill that killed them. In 2010 because there were so many oil spills happening and the manatees were so endangered rescue clinics were not allowed to release the manatees until the water was cleared up (Phillips). Chemical and nutrient pollution has also been very harming to the West Indian manatee. In 2013, 15% of the manatees died mostly due to the sewage and fertilizer runoff into streams and rivers that dump into the ocean (Guest). Agriculture immensely adds to the nutrient and chemical pollution due to the fertilizers used on crops.
With an upcoming development and world’s global climate change are causing many degradation of water and its sources. Water resources and its reservoirs are greatly being affected by anthropogenic action or natural phenomenon. When talking about water pollution, we should consider that it is not only about water quality but also about water quantity. Water pollution in Japan had been issue even before the industrialization, especially during “Japan’s Meji Period (1868-1912)”, when “Ashio Copper Mine” dumped huge amount of waste water into Watarase River and greatly hamper the residents (Water Environmental Management in Japan, n.a). It seems that with industrialization and urbanization, the water problem become more severe in Japan.
This is a factor from the agriculture that affects the eutrophication significantly. Besides the nutrients contain in the animals wastes, there are also many bacteria that affects the eutrophication. Fecal coliform and Escherichia coli are often seen in the animal wastes. When those bacteria get into the water, like many other bacteria, they will use up the oxygen in water when decomposing the dead organisms caused by algal bloom that therefore worsen the situation of eutrophication. Aquatic farming often causes the plankton bloom in the ocean surface.
Industrial corporations have continuously used bodies of water to their advantage by having their factories use water as an energy source and trash bin. Toxic chemicals are released by these factories and sometimes directly dumped back into the water. Aquatic plants benefit from the carbon dioxide released by factories, but too much can harm the biodiversity of that ecosystem and other marine life and acidity levels will also rise. A bigger population means more consumption and as the human consumption has increased throughout the years, landfills have been overflowed by large amounts of trash. When liquids and other materials begin to degrade, they release a juice that can be toxic if consumed.
The excess water flowing along the streets picks up litter, oil and other materials, which is then carried into the sea. Majority of the pollution entering the sea is from storm water drains; this is dangerous to the marine life as the water flowing through the storm water is also carrying harmful chemicals that can result in death the creatures. Impacts on the marine life There are a many ocean pollutants that threaten marine life. Pollution leads to unhealthy oceans and even death to the creatures living in it. The concern on ocean pollution is a growing problem that has no clear resolution insight.
