Water pollution is the contamination of water bodies caused by pollutants directly or indirectly discharged without treatment. Pollutants can be physical, chemical, or biological in nature. Water pollution has many negative effects including toxic rainfall, sickness, and harm to animals and plants. It can be reduced by proper disposal of industrial and residential waste, using renewable energy and eco-friendly chemicals, and individual conservation efforts.

1. Water Pollution

-Shreya Shah

2.  Water pollution is the
contamination of water bodies.
 This from of environmental
degradation occurs when
pollutants are directly or
indirectly discharged into the
water bodies without adequate
treatment to remove harmful
compounds
What is the water contamination?

3.  A contaminant is a substance that is where it shouldn't
be and is at high enough levels to have a negative
effect on our health or on the health of animals or
plants.
 A contaminant is any potentially undesirable
substance.
What is the meaning of
contaminant?

4. Categories of drinking water
contaminants
Physical contaminants
primarily impact the
physical appearance or
other physical properties
of water.
Chemical contaminants
are elements or
compounds. These
contaminants may be
naturally occurring or
man-made.
Biological contaminants
are organisms in water.
They are also referred to
as microbes or
microbiological
contaminants.

5.  1) Water pollution may be caused by the intentional or
unintentional disposal of hazardous chemicals and materials into
a body of water.
 2) Rainfall may cause polluted landscapes to disperse their
poisonous materials into the water and poison the surrounding
water.
 3) Water pollution may also be caused by specific points or
contributing factors such as large factories, oil refineries,
construction sites, chemical waste management facilities, dump
sites and other large scale operations that store/produce large
amounts of chemical/hazardous waste.
Causes of water pollution

6. Water pollution caused from point sources or
non point sources
Point sources
 Point source pollution occurs
from a specific location by a
single source such as a large
factory, oil refinery or hauling ship
that contributed a massive
amount of pollution within a
single area.
 This large scale pollution can
then be spread across large
bodies of water affecting many
miles of water, agricultural land,
animal habitats and oceanic
ecosystems.
Non-point sources
 Non point source pollution can
occur from many different areas
that all contribute to a body of
water.
 This can occur from large
neighborhoods with poor
residential lawn quality from
sewage leaks and other types of
contaminants, city streets where
garbage and chemicals are not
disposed of properly and large
agricultural areas that use harmful
chemicals which runoff into a body
of water and contribute to other
sources of water pollution.

8.  1) Toxic rainfall can occur in areas where water and/or air is
polluted with toxic chemicals and materials.
 2) Polluted water can lead to sickness, disease, infections,
deformities and even death among animals and plant life.
 3) Once water becomes polluted it can affect people and animals
either directly through consumption or indirectly through food
sources, land degradation and the overabundance of plants and
algae which can cover the surface of various bodies of water
making it undrinkable and affecting the animals that live in that
body of water.
Effects of water pollution

9. Effects on ANIMALS AND THE ECOSYSTEM

10.  Contaminated water can cause many types of diarrheal
diseases, including Cholera, and other serious illnesses such
as Guinea worm disease, Typhoid, and Dysentery.
 Waterborne diseases are caused by drinking contaminated or dirty
water.
 Water related diseases cause 3.4 million deaths each year.
What diseases can be caused by
contaminated water?

11.  Reservoirs and purification plants
 Process sewer water to drinking water
 Expose clear plastic containers to sunlight (UV)
 Nano-filters
 The Life-Straw
There Are Many Ways to Purify
Drinking Water

12.  Factories, construction sites, chemical waste facilities and other
large buildings that create large amounts of pollution should
make sure that their waste is being disposed of properly.
 By implementing renewable energy sources to run these large
operations companies can obtain their energy from eco-friendly
sources that do not harm or pollute the atmosphere.
 Eco-friendly chemicals should be used to replace toxic cleaning
chemicals, sprays and other supplies.
MINIMIZING WATER POLLUTION AND IMPROVING
THE ENVIRONMENT

13.  Toxic fumes created from industrial zones should be filtered,
rerouted and cleaned before making their way to the atmosphere.
 Companies that develop products and goods should focus on
developing materials that are eco-friendly and recyclable.
 Reduce, recycle & reuse. Companies can find better ways to
reduce the amount of materials they use to create their products,
recycle left over materials and reuse materials that may not work
with their existing products.
MINIMIZING WATER POLLUTION AND IMPROVING
THE ENVIRONMENT

14.  Replace your air fresheners with eco-friendly candles.
 Purchase environmentally friendly cleaning products that do not
harm the land if they happen to be flushed or emptied into a drain
 Conserve your water usage and don’t leave water running when
you are not using it
 Reduce, recycle & reuse materials that you have purchased.
 Use a reusable grocery bag rather than the plastic bags
