Types and Sources of Water Pollution There are several major types of water pollution. (b) The BP oil spill on June 19, 2010. Where are most of the dead zones located? Water pollution is the contamination of water bodies, usually as a result of human activities.Water bodies include for example lakes, rivers, oceans, aquifers and groundwater.Water pollution results when contaminants are introduced into the natural environment. �}��^20O6Ҍ@| � ��p Sand berms have been constructed off of the Louisiana coast to keep the oil from reaching shore. BP drilled two relief wells into the original well. This was the extent of the banned area on June 21, 2010. APES OBJECTIVES FriRel: CHAPTER 14 Objectives - WATER POLLUTION KEY OBJECTIVES: The main objective of this chapter is for students to understand the different substances that pollute our water resources and various ways we clean wastewater. Sewage disposal (some sewage is inadequately treated or untreated). Animal wastes may carry harmful diseases, particularly in the developing world. Find more customizable statistical infographic templates on Venngage. The most widespread source of water contamination in developing countries is raw sewage. That action did not receive support from the scientific community since no one knows the risks to people and the environment from such a large amount of these harmful chemicals. The inherent right and obligation of the people of all states to develop fully their water resources within the framework of applicable interstate compacts and the water laws of the respective states. Although water pollution is among the biggest human health risks, the continuing deterioration of water quality remains a major global threat. When entities containing high quantities of nutrients, such as fertilizers, domestic wastewater and sewage, enter the water bodies, these support the growth of various types of weed, algae, and other plants that are harmful to the water body. The endangered Kemp’s Ridley turtle breeds only around the Gulf of Mexico. When the relief wells entered the original borehole, specialized liquids were pumped into the original well to stop the flow. Machines that can separate oil from the water are placed aboard ships stationed in the area. :"p OBJECTIVES A. With such low numbers, rebuilding their populations after the spill will be difficult. It also increases productivity, creates employment and initiates innovation. 0000022087 00000 n Environmental pollution aims at changing climate and weather conditions. Real estate prices along the Gulf have declined precipitously. Deep water oil drilling presents an enormous threat to the economic and ecological health of the oceans as seen in the Gulf Oil Spill of 2010. c) Itai-Itai disease. Ocean pollution harms some of the most productive sources of marine life. Oil coated birds cannot regulate their body temperatures. Radioactive substances from nuclear power plants, medical and scientific sources. The original well was declared effectively dead on September 19, 2010. This means that one or more substances have built up in water to the extent of causing problems to people, animals and plants. %%EOF A dead zone is an area of hundreds of kilometers of ocean without fish or plant life (Figure below). Another source of water pollution is the burning of fossil fuels, causing air pollution like acid rain which then flows to streams, lakes, and other stretches of water.
