What is Water Pollution?
Water pollution definition goes as fallows. It is a presents of toxic chemicals or any biological agents that exceed normal levels that are found in the nature. When these levels are exceeded it may posses a threat to human health. It can even posses threat to the environment. Additional to the groundwater pollution we also pollute the big open water bodies. This is a result of multiple human activities, such as factories dumping their excess to the rivers or oil spills by faulty tankers. When these chemicals come in contact with our waters this is then called water pollution.
