This ordinary woman hid Anne Frankand kept her story alive, This Persian marvel was lost for millennia. Many solid wastes, such as plastics and electronic waste, break down and leach harmful chemicals into the water, making them a source of toxic or hazardous waste. The problem is especially acute in developing countries that may lack infrastructure to properly dispose of solid waste or that may have inadequate resources or regulation to limit improper disposal. Examples include wastewater (also called effluent) discharged legally or illegally by a manufacturer, oil refinery, or wastewater treatment facility, as well as contamination from leaking septic systems, chemical and oil spills, and illegal dumping. pollution. When rain falls and seeps deep into the earth, filling the cracks, crevices, and porous spaces of an aquifer (basically an underground storehouse of water), it becomes groundwaterone of our least visible but most important natural resources.

Routine shipping, run-offs and dumping of Thermal heating If oxygen is depleted, >microorganisms that in water and This is the template you need if youre looking to present an action plan for water pollution prevention. When the algae die, oxygen dissolved in the water declines because microorganisms use oxygen to digest algae during the process of decomposition (see also biochemical oxygen demand). by this process as well. people drink untreated water (straight Water Pollution can be defined as the contamination of water bodies, especially by chemicals or microorganisms, which are released into the water. Covering about 70 percent of the earth, surface water is what fills our oceans, lakes, rivers, and all those other blue bits on the world map.
