The presence of harmful chemicals and biological agents in groundwater that go above and beyond what is normally present in the water and may be hazardous to the environment and/or human health is referred to as water pollution. Additionally, substances that have been added to water bodies as a result of numerous human activities might constitute water contamination. Regardless of the risk they may represent to the environment and human health, any quantity of harmful substances pollutes the water. Water pollution is a hideous problem all around the world that is caused entirely by human behavior. So, what would it take to stop or in the very least reduce the rate of significant water pollution? The answer includes creating and imposing laws on how waste is disposed on a large scale, such as factories and farms, as well as educating the overall public on what each person can do to contribute to the solution instead of the problem. The major causes of water pollution in today’s society are from household sewage, industrial manufacturing, and agricultural runoff. Laws such as Clean Water Act of 1972 have been helpful but now, half a century later it is in need of an overhaul to address the polluting sources not included in the original version. Examples of which include indirect source polluting from farm and residential runoffs that carry with them pesticides, household chemicals, and even pharmaceuticals right to the steams and oceans infesting marine life and drinking waters. The ultimate solution is to come at the problem from both ends, cleanup the waste that is already in the water systems throughout the globe, but more importantly stopping or at the very least significantly cutting down on the careless polluting practices currently in place. That is why it is vital to publicize this problem, educate on the causes and effects of society’s activities, and fight for creation and enforcement of stricter laws for waste disposals.
