Water pollution is major problem in global warming
context . It has been suggested that it is leading
worldwide cause of death and diseases. And that it
accounts for the deaths of more than 14000 people
daily. An estimated 700 million Indians have no
access to proper toilet. 1000 Indian children's are die
daily because of diarrheal sickness.
If the
pollution comes from single
source is called point source
pollution
If the
pollution come from so many
sources is called non point
source pollution .
Examples of non point source :
Excess fertilizers,
herbicides, and
insecticides from
agricultural lands and
residential areas;
Oil, grease, and toxic
chemicals from urban
runoff and energy
production.
Sewage and waste waterEveryday, we cook, do
laundry, flush the toilet, wash
our cars, shower and do
many things that use water.
Think about how we use
water in schools, hospitals
and public places.
Septic TanksEvery domestic (home) toilet is
connected to septic tank usually
located outside the house. Each
time poop is flushed down the
toilet, it goes into this tank,
where the solid part is separated
from the liquid part.
Ocean and marine dumping
Again, think of the rubbish we all make
each day. Paper waste, food waste,
plastic, rubber, metallic and aluminum
waste. In some countries, they are
deposited into the sea. All these waste
types take time to decompose.
Underground storage and tube leakages
Many liquid products (petroleum products)
are stored in metal and steel tubes
underground. Other sewage systems run in
underground tubes. Overtime, they rust
and begin to leak. If that happens, they
contaminate the soils, and the liquids in
them end up in many nearby water bodies
Atmospheric
Atmospheric deposition is the pollution of water
bodies caused by air pollution.
Death of aquatic (water) animalsThe main problem caused by water pollution is that it kills life that depends on these water bodies.
Disruption of food-chainsPollution disrupts the natural food chain as well. 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.
Eventually, humans are affected
by this process as well. People
can get diseases such as
hepatitis by eating seafood that
has been poisoned. In many poor
nations, there is always outbreak
of cholera and diseases as a
result of poor drinking water
treatment from contaminated
waters.
Oil drilling, refining and
transportation have long been
a major issue especially with
marine pollution.
Use Water Wisely
By conserving water, the amount of
wastewater needing treatment and
disposal will
be reduced. Overwatering and runoff
can carry pollutants into the storm
drain
system.
Use and Dispose of Hazardous Substances Properly
Always read the product label and
choose the least toxic alternative.
Motor oil,
paints, solvents and other chemicals
should not be poured on the ground or
down
storm drains, because they can pollute
our streams and ocean.
Educate Others
Offer an individual or class project to
inform others about protecting our
ocean from pollution.
Improve Housekeeping
Report water leaks so that we may
any fix water leaks on our campus
by replacing
faucet washers and toilet flappers as
needed.
Study Storm Water Management
Students may elect to learn more
about hazards associated with illicit
discharges to
our storm drains and streams, then
develop steps that can be taken to
reduce storm
water pollution.
