Created with Fabric.js 1.4.5 Many ocean pollutants are released into the environment this excess nutrients can spawn massive blooms of algae that rob the water of oxygen, leaving areas where little or no marine life can exist. SEAS Many ocean pollutants are released into the environment far upstream from coastlines.can come from point sources, or a single identifiable source, such as factories or wastewater treatment facilities It can take many forms from industrial, agricultural, or municipal sources In the Humans if theydrink water contaminated and in all who is living there Water pollution prevention and control measures are critical to improving water quality and reducing the need for costly wastewater and drinking water treatment RIVERS Common man-made pollutants that reach the ocean include pesticides, herbicides, chemical fertilizers, detergents, oil, sewage, plastics, and other solids. Many of these pollutants collect at the ocean's depths, where they are consumed by small marine organisms and introduced into the global food chain. LAKES Forms: Examples of such pollutants include cyanide, zinc, lead, copper, cadmium and mercury. Who is affected? Methods to control water pollution: Impact Cause: Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). This form of environmental degradation occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds. WATER POLLUTION (lakes, rivers and oceans) These substances may enter the water in such high concentrations that fish and other animals are killed immediately.Sometimes the pollutants enter a food chain and accumulate until they reach toxic levels, eventually killing birds, fish and mammals. Dirty water containing chemicals from the factory is put back in the river. Water used for cooling is warmer than the river itself. Raising the temperature of the water lowers the level of dissolved oxygen and upsets the balance of life in the water. My solution: Decisions on the type and degree of treatment and control of wastes, and the disposal and use of adequately treated waste water, must be based on a consideration all the technical factors of each drainage basin, in order to prevent any further contamination or harm to the environment.
