The simplest water pollution definition would be any contamination of water bodies with some pollutant(s) that changes physical, biological, and chemical conditions of any body of water making this water harmful for environment and surrounding ecosystems. Water pollution occurs once too much pollutants (mostly in form of different waste) are discharged directly or indirectly into water bodies. Water pollution does not only cause great environmental damage but is also the leading worldwide cause of deaths and diseases responsible for the deaths of more than 14,000 people each day, mostly in developing countries. Many people are not aware that water pollution is serious problem in almost all parts of the world, and not just in third world countries like some choose to believe. In fact many experts will tell you that reality is completely different than the common belief, and that actually water pollution problem is already out of control. Water pollution problem is in most cases connected with the careless handling of chemical agents, toxins introduced into our water through industrial dumping, and farm runoff. All these factors make our water unsafe to drink. For instance, the chlorine that is widely used to disinfect our water is believed by many to be carcinogenic, and therefore a major health issue that significantly contributed to worldwide rise of cancer rates. Basically chlorine is present in every glass of water we draw from our tap, and although some studies have confirmed that chlorine can indeed be one of the cancer risk factors we simply cannot do without it because by removing chlorine from our water we would open the door to many waterborne diseases that would kill millions of people around the globe.
