Algaecides, Biopesticides, Biocides, Fungicides, Herbicides, Insecticides, and Matricides. There are hundreds of names for all these American-made chemicals. Most of them are good for plants but most of them are bad for humans and animals. Scientists are conducting tests and studying these harmful chemicals because of concern of pesticides getting into our main water systems. Some of the problems with chemicals getting into our water systems are that the soil can only hold so much liquid, the rest of the chemicals run off into our streams and creeks.

With chemical water pollution being our focus in this essay, it is the most dangerous form of water pollution in our water bodies. They are usually colourless, odourless, & tasteless. Water pollution may also affect the marine environment & food chain, affecting many species in a catastrophic manner. With so many impacts of water pollutions, which will be discussed in great details below, we need to make a change now to the way of our living, work, & how our industries & agricultural systems work. This essay will focus on chemical pollution in great detail, as it is the main biggest pollutant of our water.
Agricultural runoff is water from cropland or livestock operations that flows into a body of water. It does not have one direct source that it comes from, and that is why it is hard to control. Scientists call that a diffuse source of pollution. It is the number one category of nonpoint source pollution (NPS) in rivers and lakes. Non-point source ... ... middle of paper ... ... have to spend so much to try to clean the water out.
Recycle b. Conserve water c. Don’t litter d. Prevent oil leaks Water pollution is one of the main concerns of the environment. It is known as a change in the chemical or physical condition of the waters. Polluting the waters is causing harmful and tragic diseases that affect many families. It is also a global problem that not only affects people but also animals and plants. Water pollution is a current issue that has serious consequences; it progresses everyday in our lakes, oceans, rivers and other bodies of water.

Occasionally, the decomposition of newly-submerged biomass and sediment further reduce the water's oxygen content. Water sources can literally choke to death as a result of increasing human activity, such as industry and agriculture giving rise to increased nutrient loading. I am particularly surprised how the agricultural industry inflicts these problems on themselves, by excessive use of sewage systems and pollutants which find their way to local rivers [Fig 1.]. The trophic state (i.e. the natural nutrition factors) and biodiversity of lakes and rivers are greatly effected by the main nutrients involved, nitrates and phosphates.
Man’s Effect on the Environment 1) SOURCES OF POLLUTION Freshwater Environments : Man pollutes freshwater all over the world in many ways there is much waste and pollution that ends up in rivers. One of the main hazards is called eutrophication, this process becomes enriched with artificial nutrients from fertilisers which run off into the rivers and upset the natural nutrient cycle of the river, lake or pond. The water turns green because of the algae which when they die multifly using up all the oxygen. Similar consequences occur if raw sewage is pumped into a river. Chemical waste from factories dump their un wanted waste into rivers, lakes or ponds as well.

Solutions So far the solutions that people and scientists have come up with are to make the farmers use fewer fertilizers, time when you use your fertilizers and control waste. Using fewer fertilizers and controlling waste are the most obvious solutions, as they would directly prevent nitrogen and nitrates from being in the water. They are the hardest to achieve though because the farmers need them to grow their plants.
