Euthrophication is caused by excess nutrient run off, such as nitrogen or phosphorus. A common chemical that generally cause euthrophication is fertilizers from farm, if there's heavy rainfall or floods, they're easily washed into the rivers and lakes to cause euthrophication.
Euthrophication generally cause a sudden large scale algao bloom, or other plants, and they may cover the whole surface of water. Once these plants die, decomposers such as bacteria decompose them and take in oxygen for respiration, such that animals from the river originally may die due to lack of oxygen.

Answer: detoxify and decompose waste
Explanation:
Billions of tonnes of organic waste is processed every year by earth’s decomposing organisms. Industrial waste including detergents, oils, acids and paper are also detoxified and decomposed by the activities of living things. Well you could say that bacteria, algae and worms break down organic materials and release essential nutrients to plants. The Nitrogen Cycle is a good example. And there are many flowering plants rely on the activities of various animal species – bees, butterflies, bats and birds to help them reproduce through the transportation of pollen. More than one third of humanity’s food crops depend on this process of natural pollination.
And if Crop pests are controlled by organisms such as insects, birds and fungi, which are a much better form of pesticide than chemical pesticides that can harm plant and water sources yes your answer is detoxify and decompose waste. (:
