Water pollution is a major global problem which
requires ongoing evaluation and revision of water
resource policy at all levels (international down to
individual aquifers and wells). It has been
suggested that water pollution is the leading
worldwide cause of deaths and diseases, and that
it accounts for the deaths of more than 14,000
people daily. An estimated 580 people in India die
of water pollution related illness every day.
Introduction
 Around 90% the water in the cities of China
is polluted, and as of 2007, half a billion
Chinese had no access to safe drinking
water. In addition to the acute problems of
water pollution in developing countries,
developed countries also continue to
struggle with pollution problems.
What is Water
Pollution?
Water pollution is any chemical, physical or biological
change in the quality of water that has a harmful
effect on any living thing that drinks or uses or lives in
it. When humans drink polluted water it often has
serious effects on their health. Water pollution can
also make water unsuited for the desired use
Where does water pollution come from?
Water pollution is usually caused by human activities. Different
human sources add to the pollution of water. There are two sorts
of sources, point and nonpoint sources. Point sources discharge
pollutants at specific locations through pipelines or sewers into
the surface water. Nonpoint sources are sources that cannot be
traced to a single site of discharge.
Examples of point sources are: factories, sewage treatment plants,
underground mines, oil wells, oil tankers and agriculture.
Common causes of water pollution
Sewage and wastewater: Out of sight, out
of mind? Surfers will tell you that sewage
contains all kinds of horrific nasties, from
sanitary products, condoms, paper, and
plastics, to bacteria and viruses that can
make you extremely ill.
Soaps and washing detergents: Phosphates in
detergents can fertilize rivers and seas, causing
algal blooms that use up oxygen and kill fish life.
Oil poured down the drain: You might think oil
tankers make the most oil pollution, but quite a
lot of oil enters water simply by being tipped (or
washing) down the drain.
Invasive species: Often carried around the world
by ships, they suddenly appear in rivers, lakes, and
seas where they have no predators, quickly wiping
out their natural rivals.
Water pollution solutions
Understanding causes: If we don't understand why
pollution happens, how can we hope to stop it? We
need to know whether pollution is point source or
nonpoint source—and what causes it in each case.
Legislation: There are many different anti-
pollution laws and agreements in operation in the
United States, Europe, and worldwide. Examples
include the US Clean Water Act, the EU Bathing
Water Directive, and the MARPOL International
Convention for the Prevention of Pollution from
Ships.
Regulation: Sometimes pollution seems
unavoidable: from papermaking to oil refining,
many industrial processes create pollution as a
byproduct. But instead of accepting that as a
fact, we can regulate factories and allow them to
emit or discharge only limited amounts of
carefully controlled pollutants. By slowly
reducing the levels of permitted discharges, year
by year and decade by decade, we can gradually
bring pollution under control.
CONCLUSION
 Water pollution is bad and it’s not good for people to drink the
water that’s polluted and for all organisms that need water to
survive.
 There are millions of people that don’t have good clean access to
water and that they even have to drink the bad polluted water for
them it survive, Sewage can cause water pollution along with the
toxic chemicals from Industrial business.
 There are a bunch of water pollutions like toxic and organic and
thermal water. And solutions to stop the water pollution are to
clean up the garbage and keep your yard clean.
 To try to stop the water pollution clean up your yard and make
sure there is no garbage left anywhere around in the area you live
like the streets and neighborhood.
