2. WHAT IS WATER POLLUTION?
• WATER POLLUTION IS THE CONTAMINATION OF WATER BODIES (E.G.
LAKES, RIVERS, OCEANS, AQUIFERS AND GROUNDWATER), VERY OFTEN
BY HUMAN ACTIVITIES.
• IT OCCURS WHEN POLLUTANTS (PARTICLES, CHEMICALS OR SUBSTANCES
THAT MAKE WATER CONTAMINATED) ARE DISCHARGED DIRECTLY OR
INDIRECTLY INTO WATER BODIES WITHOUT ENOUGH TREATMENT TO GET
RID OF HARMFUL COMPOUNDS.

3. ANY CHANGE OR MODIFICATION IN THE PHYSICAL, CHEMICAL
AND BIOLOGICAL PROPERTIES OF WATER THAT WILL HAVE A
DETRIMENTAL CONSEQUENCE ON LIVING THINGS IS WATER
POLLUTION.

4. SOURCES OF WATER POLLUTION
• POINT SOURCES
• NONPOINT SOURCES

5. POINT SOURCE
• POINT SOURCE OF WATER POLLUTION REFERS TO THE POLLUTANTS
THAT BELONG TO A SINGLE SOURCE. AN EXAMPLE OF THIS WOULD
BE EMISSIONS FROM FACTORIES INTO THE WATER.

6. NON-POINT SOURCE
• NON-POINT ON THE OTHER HAND MEANS POLLUTANTS EMITTED
FROM MULTIPLE SOURCES. CONTAMINATED WATER AFTER RAINS
THAT HAS TRAVELLED THROUGH SEVERAL REGIONS MAY ALSO BE
CONSIDERED AS A NON POINT SOURCE OF POLLUTION.

7. EFFECTS OF WATER POLLUTION
• DEATH OF AQUATIC ANIMALS: THE MAIN PROBLEM CAUSED
BY WATER POLLUTION IS THAT IT KILLS LIFE THAT DEPENDS ON
THESE WATER BODIES. DEAD FISH, CRABS, BIRDS AND SEA GULLS,
DOLPHINS, AND MANY OTHER ANIMALS OFTEN WIND UP ON
BEACHES, KILLED BY POLLUTANTS IN THEIR HABITAT (LIVING
ENVIRONMENT).

8. • DISRUPTION OF FOOD-CHAINS: POLLUTANTS SUCH AS LEAD AND
CADMIUM ARE EATEN BY TINY ANIMALS. LATER, THESE ANIMALS
ARE CONSUMED BY FISH AND SHELLFISH, AND THE FOOD CHAIN
CONTINUES TO BE DISRUPTED AT ALL HIGHER LEVELS.
• DISEASES: PEOPLE CAN BE AFFECTED WITH DISEASES SUCH AS
HEPATITIS.

9. • DESTRUCTION OF ECOSYSTEM: ECOSYSTEM CAN BE
SEVERELY CHANGED OR DESTROYED BY WATER POLLUTION. MANY
AREAS ARE NOW BEING AFFECTED BY CARELESS HUMAN
POLLUTION, AND THIS POLLUTION IS COMING BACK TO HURT
HUMANS IN MANY WAYS.

10. PREVENTION OF WATER POLLUTION
• NEVER THROW RUBBISH AWAY ANYHOW. ALWAYS LOOK FOR THE
CORRECT WASTE BIN. IF THERE IS NONE AROUND, PLEASE TAKE IT
HOME AND PUT IT IN YOUR TRASH CAN. THIS INCLUDES PLACES
LIKE THE BEACH, RIVERSIDE AND WATER BODIES.

11. • USE WATER WISELY: DO NOT KEEP THE TAP RUNNING WHEN
NOT IN USE. ALSO, YOU CAN REDUCE THE AMOUNT OF WATER YOU
USE IN WASHING AND BATHING. IT WILL SIGNIFICANTLY PREVENT
WATER SHORTAGES AND REDUCE THE AMOUNT OF DIRTY WATER
THAT NEEDS TREATMENT.
• DO NOT THROW CHEMICALS, OILS, PAINTS AND MEDICINES DOWN
THE SINK DRAIN, OR THE TOILET

HAVE A GOOD
DAY
