!!!!!!!!!!!!!!!!!!
2What is
NON-POINT SOURCE POLLUTION?!
Pollution that finds its way into all types of
water bodies.
Because of erosion caused by land, air, and
water, non-point source pollution can travel
directly into water bodies.
Human activities create non-point source
pollution, and due to runoff from cities,
suburbs, and farms, such pollution is a major
threat to our environment.
Non-point source pollution drastically affects
water quality. It clouds water, reduces the
waters oxygen supply, and negatively affects
organisms that depend on the water quality.
3So, you say,
Give me some examples of non-point source
pollution already!
Well, okay
4Pollutants that are emitted into the air such as
nitrogen, which are created by
CARS
POWER PLANTS
INDUSTRY
5The chemicals used for
GARDENS
LAWNS
PESTICIDES
ANTI-FREEZE
etc.
OIL
PAINTS
BRAKE FLUID
COOKING OILS
6Agriculture is a large source of non-point source
pollutants.
PESTICIDES,
AND IMPROPER CULTIVATION PRACTICES
OVER-GRAZING
(???)
all increase soil erosion and runoff.
7Construction upsets sediment levels and allows
for increases in erosion and sedimentation.
This allows non-point source pollutants to travel
into water bodies.
8Mining practices sometimes allow drainage to
occur.
Because of erosion and sedimentation, the
drainage travels into water bodies.
9Yeah, well, how does the Water Cycle contribute
to erosion and surface runoff? Lets hear it,
smarty pants.
Alright
10If soil is not properly managed, there will be a
decrease in the amount of water that soaks into
the soil.
(WATER)
Instead of going here
the water goes here.
11With an increase in water running over the
surface, there will be a definite increase in
erosion and increased amounts of non-point source
pollution traveling to bodies of water.
12Alright, alright So whats the value of buffers?
Well
Buffer Strips help prevent runoff and
sedimentation from reaching bodies of water.
By maintaining permanent vegetation designed to
intercept pollutants, we can enhance wildlife
habitats, improve water quality, and enrich
farmlands which produce our food.
13Riparian Forest Buffers
- Riparian forest buffers are streamside vegetation
consisting of trees, shrubs, and grasses that can
intercept pollutants from both surface and ground
waters before they can reach a body of water. - Tree and grass buffers can remove up to 50 of
the nitrate and phosphate found in runoff. When
an excess of these nutrients enter water bodies,
they dramatically hurt our environment in a
variety of ways. - By utilizing riparian forest buffers, our water
quality will be improved, and because water is
needed for life, our entire environment will
flourish.
14When deciding to develop and maintain a
conservation buffer strip, one should not use
invasive plants. Invasive plants grow
aggressively, spread, and displace other plants.
These types of plants are difficult to control,
can escape from cultivation, and can dominate
whole areas. In short, invasive plants can be
environmentally destructive. It is better to use
native plants for buffer strips. Native plants
are already adapted to the region, and they will
not cause destruction.
15Well, why dont you tell me how degraded stream
banks can be restored, if you have all of the
answers already. How about that, huh?
Okay
- Fences prohibit livestock from having access to
the water directly, as well as water body banks. - Ramps and crossings provide limited, structured
access to the waterway.
16This all sounds nice and good, but arent there
any conservation practices that we can enact as
responsible citizens?
YES!
17Construction of fences to prohibit animals
access to water bodies.
Development of proper buffer strips made of
native vegetation.
Properly maintain chemical use and disposal in
urban and the surrounding areas.
18Without conservation, everything can be affected.
Farmland
Drinking Water
Fishing
Swimming
Lets help to maintain a suitable environment for
all creatures to live!
19Thank you for listening attentively and with open
minds.
ANY QUESTIONS?
(ANY AT ALL, REALLY)
Oh come on, ask us something
