Water Pollution And Its Impacts On Water Body - 1682 Words

1.1 Back Ground Among all natural resource, water is one of the most important to sustain the living planet, earth and every form of life on its face, including human being. It is an integral part of human’s activities including domestic, agriculture, transport, industry, power generation and recreation. Moreover, the normal uses of human body depends entirely on adequate quantity and quality of water. But pure water does not exist by default in its quality due to natural interaction among the earth’s subsystems, especially anthropogenic activity around urban area . Water pollution is the state of change in the natural physical, chemical, biological, bacteriological and radiological properties of water that causes in an impairment of its inherent (Susan Joy 1998) .Many investigation were carried out by many researchers and organization over past year to assess the source of pollution and its impacts on water body. Among the source of pollution the major pollution from Nonpoint source (NPS) was urban runoff and it has been established as a major cause of receiving water degradation ( VASSILIOS A. TSIHRINTZIS and RIZWAN TSIHRINTZIS , 1997)) and additionally USEPA stated that urban storm water runoff in the U.S.A. is the fourth most extensive cause of water quality impairment of rivers, and the third most extensive source of water quality impairment of lakes regardless of 1988 report to the Congress, (EPAUS, 1999) Storm water runoff is water that runs off imperviousShow MoreRelatedAquatic Ecology : The Science Of Ecology1555 Words   |  7 PagesAquatic ecology is the science of ecology which concentrates on the study of aquatic ecosystems. This field can be broken out into two divisions: freshwater and marine ecology. Understanding aquatic ecosystems is critical since water is the building block to the survival of all life on earth. Aquatic ecology includes the study of aquatic environments including oceans, lakes, ponds, wetlands, rivers, and streams. Every organism needs energy to live, grow and reproduce. In aquatic ecology, biologistsRead MoreThe Effects Of Indiana s Activities Impacting Ocean Life Through Nutrient And Sediment Pollution1227 Words   |  5 Pagesthrough nutrient and sediment pollution. There is a multifarious number of reasons that could affect ocean life, even in Indiana, which one will discuss throughout this report. One will describe sediment runoff, the manageme nt of pollution, and even soil erosion. All of these interesting topics lead to the reason Indiana has a slight but affective impact on the ocean. One main issue that could affect our local air quality and the oceans, is climate change (â€Å"Midwest Impacts Adaptation†) Indiana hasRead MoreWater Pollution And Its Effects On Aquatic Life1526 Words   |  7 Pages Water Pollution and its Effects on Aquatic Life Charles Darwin, the father of evolutionary biology, states in his theory of evolution that only organisms better fit to survive in their environment will survive. Based on his theory and research, it can be concluded that challenges to the environment directly affect the organisms. Research shows that in particular water pollution; hospital wastewater and sewage wastewater, is shown to cause antibiotic-resistant microorganisms, excess nutrients suchRead MoreCauses and Effects of Water Pollution1292 Words   |  5 Pagesof our Earth surface is covered by water and almost 60% of the human body contain water for nutrient transportation.
