Point source pollution is easy to identify because it comes from a specific source. One example of point source pollution is the pollution that comes from a power plant. Each of these pictures is of a point source polluter.Industries will often dump pollutants that end up in groundwater. These contaminants then become part of the drinking water supply. Underground storage facilities and landfills can also contaminate groundwater.

2. Point Source
Pollution
Point source pollution can be
traced back to its source.

4. Non-Point
Source
Pollution
Stormwater runoff is a great example of non-
point source pollution.
Stormwater happens when precipitation lands
on paved surfaces such as sidewalks, streets,
rooftops, and such, and picks up pollutants,
carrying them into bodies of water.
Farms and rural areas also contribute to non-
point source pollution.

5. Non-Point
Source Pollution
• Agricultural runoff causes
excessive algae growth on surface
water.
• When eutrophication occurs,
oxygen is blocked from entering the
water and can lead to the death of
fish.
• Acid rain is another non-point
source pollutant.

6. Non-Point Source
Pollution
• Acid rain is precipitation that has a lower pH
than normal rain. Normal rain has a pH of 5.0 -
5.5. Acid rain is caused by the burning of fossil
fuels. As fossil fuels are burned, sulfur oxides
(from coal burning) and nitrogen oxides are
released into the atmosphere. Once in the
atmosphere, these substances combine with
water in the atmosphere to create sulfuric acid
and nitric acid respectively. This then falls to
Earth as acid precipitation into soil and bodies
of water. This acid precipitation can lower the
pH of bodies of water and can damage these
ecosystems.

7. Groundwater Issues
Industries will often dump pollutants that
end up in groundwater.
These contaminants then become part of the
drinking water supply.
Underground storage facilities and landfills
can also contaminate groundwater.

8. Subsidence
• Subsidence is caused by removing too much
• groundwater and can create sinkholes.

9. Estuaries and
Wetlands
• Wetlands and estuaries are very diverse
ecosystems. Remember that estuaries are
ecosystems that are covered in water parts
of the year and have less water coverage at
other times of the year. These are also
areas covered in brackish water. In
addition to being diverse ecosystems,
wetlands and estuaries are important for
holding excess water to prevent flooding
inland as well as important filters of water.

10. Estuary and Wetland
Pollution
• As development increases in areas near wetlands and
estuaries, runoff can increase and degrade these important
ecosystems. Often roads and other development can destroy
these areas.
