WHAT IS IT?
When Pesticides, nutrients, and fertilizers are picked up and then deposited into
large bodies of water
Type of Nonpoint Source
tants are picked up and transported
during rain and snowmelt events. The rain/snowmelt picks up humans made
pollutants and transport them into rivers, lakes, etc.)
IMPORTANCE TO BEING STOPPED
Deadly effects on human health:
Destroy rivers, ponds, and wetland’s ecosystems
Ruin swimming and boating
When humans are careless they

HOW DOES AGRICULTURAL
Runoff collecting loosen soil and then
depositing it in ponds,
causing burying of plants, larva, clouds water, can clog gills of fish, and many times
fertilizers and pesticides are mixed in this soil.
ss fertilizers are applied the excess is picked up in rainwater,
and carried to aquatic ecosystems causing algae bloom, which depletes the oxygen
of the pond. It can also run into drinking water
water with foul
Animal Feeding Oper
If farmers keep all their animals in tight confined
spaces they create an enormous amount of waste. Runoff from these farms that are
badly maintained can carry bacteria, viruses, excess nutrients, and more that can
cause problems in the water it i
s carried to. It can also be carried to drinking water
spreading bacteria and viruses.
When cattle overgrazes in an area it cause the soil to be exposed
making it easier for sedimentation to occur,
which can destroy aquatic ecosystems
s state above.
can cause erosion and carry nutrients
and pesticides to aquatic life.
When farmers over apply pesticides, they can runoff into aquatic life
and drinking water contaminating it.
Control the flow of water which would help keep the soil in place,
Farmers can create management plans that would make sure not
to over use fertilizers, while still maintaining the amount
of crops and saving money
by not overusing the fertilizers
Animal Feeding Operations
Ranches and farmers need to make sure that their
animal’s wastes are disposed of in a correct manner, and by managing wastewater.
Farmers need to ensu
re the fact that their animals are not
overgrazing an area, which can cause soil to loosen. Provide animals with
sources to graze, find shade, water etc.
Control amount of water applied to plants, no need to
Also farmers can switch to more
Farmers should use Integrated Pest Management. These techniques base
the amount of pesticides used on specific soil, climate, pest history, crop conditions
This limits pest
icides to only NECCASARY
WHAT CAN YOU DO?
Dispose of pet was
te, leaves, and debris properly. If not
properly, it can
end up in outlets that lead directly into ponds, lakes, etc.
Don’t over apply fertilizers
. Follow directions on the packet.
Dispose of household
correctly, such as paint, oil,
and antifreeze. For
example, household chemicals
an lead to spilling which would travel to drains
when it rains
Clean your car
’s oils, grease, and antifreeze. This should be done on grass because
the soil absorbs moisture.
Use detergents, and cleaning products low in phosphorous and oth
