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.
