Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). This form of environmental degradation occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds.Water pollution affects the entire biosphere – plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and population, but also to the natural biologicalcommunitieS.

The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese, etc.) the concentration is often the key in determining what is a natural component of water and what is a contaminant. High concentrations of naturally occurring substances can have negative impacts on aquatic flora and fauna.Oxygen-depleting substances may be natural materials such as plant matter (e.g. leaves and grass) as well as man-made chemicals. Other natural and anthropogenic substances may cause turbidity (cloudiness) which blocks light and disrupts plant growth, and clogs the gills of some fish species.Many of the chemical substances are toxic. Pathogens can produce waterborne diseases in either human or animal hosts

Human wastes and waste water from homes and other buildings are sometimes dumped into rivers and lakes.If people drink polluted water, they can get very sick.The water supply is getting worst for the animals as well for humans.

- Conserve water by turning off the tap when running water is not necessary.-Don’t throw litter into rivers, lakes or oceans.-Be careful about what you throw down your sink or toilet. Don’t throw paints, oils or other forms of litter down the drain.
