Did you know that there is
pollution all over the world?  Well today
I am going to be talking about pollution in Wisconsin. 
Everyone needs clean water for something.  People use water for drinking, growing crops
and to operate factories.  Many different
wildlife animals depend on water to live such as fish, beavers, otters and any
animal that drinks water to survive. 
There are lots of pollutants’ that can harm and contaminate our rivers,
streams and lakes.  Soil, nutrients and
bacteria are the three most common.  Rain
can be a very big problem because when it rains and the rain doesn’t soak into
the ground the rain can bring that dirt into our streams and rivers.   When the soil gets washed into the streams
and rivers it can kill fish eggs and tiny animals.  Soil can also get into fish gills and clog
them up.  It can also block out the sun
which can result in plants dying because of the lack of sun light.  The nutrients in fertilizer can also cause
problems in lakes, ponds and reservoirs. 
Algae grow from nitrogen and phosphorus and it can turn the lake
green.  Bacteria usually from sewage
spills can pollute the water.

Two types of water resources that are affected by pollution
are ground water and surface water. 
Pollution can occur in two different ways.  There is two different ways in which
pollution can occur. According too explainthatstuff.com/waterpollution

 When pollution comes from a single location
such as a discharged pipe attached to a factory, it is known as point-source
pollution.  Some examples of point source
pollution are oil spills from a tanker, a discharge pie from a smoke stack or
someone pouring oil from there car down a drain.  A big source of water pollution happens not
from just one single source but from many different scattered sources.  This pollution is called nonpoint-source
pollution.  At the point when
point-source pollution enters the environment the place most affected is
usually the area immediately around the source. 
For an example when an oil tanker accidentally occurs the oil slick is
concentrated around the tanker itself and in the right conditions the pollution
disperses the further away from the tanker you go.  This is not as likely to happen from a non-point
source pollution from the definition enters the environment from many different
places at once.
