EUTROPHICATION
A
process in which nutrients and sediments from near water or environment enter
into a waterbody and increase in its fertility and make it shallower. But due
to human activities and other reason this natural process gets faster and cause
aging of lakes and making it less recreative for sustaining life due to more
algal blooms and plant growth.

aging of lakes and making it less recreative for sustaining life due to more
algal blooms and plant growth.
CAUSES OF EUTROPHICATION
Eutrophication
is actually the aging process of lakes which is natural. The natural
eutrophication occurs after thousands of years when the lake gets old but human
speed up this process by discharging the nutrients into the lakes which cause
Lake Eutrophication.
The causes of Lake Eutrophication are:
Fertilizers
When
human keep on using nitrate and phosphate fertilizers on the golf courses,
fields and on lawns these nutrients get washed by the rain water and runs into
the rivers, lakes and oceans. The algae, plankton and the aquatic plants fed on
them and through this they increase the photosynthetic activity. As a result
algal blooms grow and increase in the plant life which results in Lake
Eutrophication.
Animal
Feeding Operations
Concentrated
Animal Feeding operations discharge nutrient that easily find their way to the
lakes, nearby water bodies, rivers and oceans and there they accumulate causing
the production of algal Blooms and Cyanobacteria.
Sewage
and Industrial Water Discharge
Sewage
water system and hand pumps are not very advanced in the developing countries, they discharge
their water directly into oceans, lakes and river. The sewage water contains
high amount of the different nutrients which cause the high growth of aquatic
plants and nutrients which cause harm to the fishes and all the aquatic
animals. The same results are with the discharge of industrial waste water. It
shows the same outcomes because it contains large amount of chemical nutrients
which causes Lake Eutrophication.
Aquiculture
The
Aquiculture is the technique to grow the fishes, aquatic plants and shell
fishes in the controlled environment without soil which contains nutrients for
their growth. If the Aquiculture is not properly managed this can cause lake
eutrophication. The nutrients and the food particles which are not fully
consumed along with the fish excretion when discharged in the water bodies it
causes the synthesis of Algal blooms and the microscopic floating plant.
Natural
Events
Some
of the natural events like flood causes the flow of nutrients from the land to
the water bodies and cause the growth of algal blooms.
Reduction
of Self Purification Capacity
When
the lakes grow old over the years, they accumulate the large quantity of
sediments (solid material transported by water). These sediments are able to
absorb nutrients and pollutants. Over time these sediments start filling the
basin and increase the interaction of water with these sediments which causes
the resuspension of nutrients that are present at the bottom is facilitated.
This harms the water quality and cause lake eutrophication.
Accumulation
of Inorganic Contents
The
process of eutrophication happens due to phytoplankton and inorganic nutrients
accumulation in the water body. Inorganic nutrients such as nitrogen and
phosphorus, play an active role in the process. Some of this nutrient
accumulation is caused by periodic flooding and rains, which bring different
type of chemicals to the water. However, the main culprit for spread inorganic
chemicals is human interference, including run-off from lawns or fertilizer
manufacturers. The introduction of nitric and phosphoric acids makes the
environment a temporarily acidic nutrient haven for plant life.
