Water pollution

The main sources of pollution are all resulted from the disposal of chemical substances coming from medical, industrial and household waste, chaotic agricultural fertilizers disposal and accidental oil spills  that pollute the water to a large extent. Major water pollutants that affect human health: Numerous infectious agents that contaminate the water through sewage, human waste and animal excreta.

What is water pollution? Water pollution  is defined as the presence in groundwater of toxic chemicals and biological agents that exceed what is naturally found in the water and may pose a threat to human health and/or the environment. Additionally, water pollution may consist of chemicals introduced into the water bodies as a result of various human activities. Any amount of those chemicals pollutes the water, regardless of the harm they may pose to human health and the environment. Causes: Chlorinated solvents commonly used in industry are examples of such chemicals polluting our water exclusively due to human activities.Regardless of their provenance, the chemicals or biological agents causing water pollution are generically referred to as water pollutants.The  chemicals or biological agents causing water pollution are  generically referred to as water pollutants.  Types of water pollutants I) Chemical  – when various chemicals are the...
