We all contributed different sections of work on a Google Doc but Liam and Emma were the ones who moved it over to this Padlet.

Eutrophication is the process of a water body becoming filled with minerals and nutrients. It can also be seen as the increase of phosphorous and nitrogen among other things. It is a problem because it can lead to algal blooms which consume all the oxygen in the water, leaving none for the other marine life.

Improvement of waste treatment plants

Less fertilizer use

Better animal husbandry to reduce wastewater

Addition of oxygen to water

Reduces algae growth

Excessive floating plant growth

Looks ugly and not clean, but that’s minor

Algae thrives when there is a lack of oxygen in water and many nutrients, so it grows well using anaerobic respiration in nutrient rich bodies of water.

Taints drinking water

Reduction of Self Purity Capacity: Sediments at the bottom, accumulate, and fill the basin. These sediments take in a lot of nutrients that could lead to deterioration of the

Severely depletes oxygen levels

Lowers the PH of the water

Especially in summer and spring.

Kills fish

Reduction of quality fish and impacts fishing

Loss of recreational areas

Not able to use the lake for touristic purposes from different kinds of algae that can irritate the skin.

Natural

Natural accumulation of nutrients in a water source over time

This leads to changes in species composition in the environment

Begins to affect water quality and the colonization of terrestrial vegetation that cause harm.

Happens over centuries worth of time

See “Causes”

Cultural

Human activity resulting in a rapid nutrient increase within decades

Results in the need of environmental management and land policies.

See “Causes”

Fertilizers

Extra nutrients in fertilizer

Concentrated animal feeding operations

Discharge high amounts of nutrients that accumulate in the water bodies

Direct waste dumping into bodies of water

Introduces chemical nutrients which stimulate the growth of algal blooms

Threatens survival of aquatic life

Agriculture

A technique of growing organisms in water containing dissolved nutrients

If not properly managed, levels of nitrogen and phosphorus will increase which results in the dense growth of floating plants

Natural events

Events such as floods can wash excess nutrients into water bodies which causes excessive growth of algal blooms

Older lakes can naturally accumulate sediments with phosphorus and other nutrients
