articles each share important reasons to why nitrates are so bad and the effect it has on people. Some problems are‚ that nitrates are costing cities way too much money‚ the struggle it puts on farmers‚ and the fact it is one of the causes to eutrophication. After reading the article‚ Iowa’s Nasty Water War‚ written by Clay Masters(2016)‚ it is hard to believe how much money is being spent removing nitrates from rivers. Nitrates have become a regular problem in Iowa’s rivers and because of this

Water is a very important part of our lives. We use it for nearly everything – drinking‚ food preparation‚ laundry‚ dishes‚ hygiene‚ etc. We swim in it‚ boat in it‚ and play in it. In fact‚ 70% of our world is covered in water. However‚ 97% of that water is saltwater and we are unable to drink it‚ leaving only three percent of the planet’s water drinkable. But two percent of the world’s freshwater is frozen in glaciers and ice caps. Only one percent of this freshwater can be used and consumed. Therefore

An eco-column is used to model an ecosystem on a smaller scale. The purpose of an eco-column is to examine how an actual ecosystem would respond to different conditions. Eco-columns typically have three chambers: the aquatic chamber‚ decomposition chamber‚ and terrestrial chamber. The aquatic chamber contains water and an aquatic plant‚ and it is at the bottom of the eco-column. The decomposition chamber contains items that will work as decomposers and as a possible catalyst for plant growth. Examples

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities.

Over the last couple of decades‚ the Indian River Lagoon (IRL) has seen an increasing amount of algal blooms caused by an excess of nutrients‚ most notably nitrogen (N) and phosphorus (P). Algae being “photosynthetic microorganisms that are found in most habitats” (SJRWMD‚ 2007) and algal blooms being defined as a “rapid increase in the density of algae in an aquatic system... [that is] increased by nutrient pollution” (SJRWMD‚ 2007). Algae blooms contribute to the continuing loss of marine life

The content in this report will comment on the various implications of science on society and the environment‚ such as the use of CFCs‚ the use of soaps and detergents‚ shrinking world resources‚ eutrophication‚ heavy metal pollution and poisoning‚ and the role of chemists. The information in this report was obtained from a wide variety of resources‚ as in the bibliography‚ which have each been assessed for their reliability and validity. 1. CHEMISTS

As we have seen that is very wrong‚ here are a few of the problems ocean pollution cause: Toxic metals can destroy the biochemistry‚ behavior‚ and reproduction of marine life. Fertilizer runoff creates eutrophication that flourishes algal bloom (rapid increase or accumulation in the population of algae in aquatic systems) which depletes the oxygen content in the water that affects marine life. Today‚ in many parts of the world‚ sewage water is discharged in

farmers‚ there are some environmental concerns that come along with it. Runoff from fertilizers often finds its way into water ways. The nitrogen rich runoff can lead to eutrophication in these water ways. The lack of dissolved oxygen in the water leads to cloudy and discolored water along with a void of animal life. Eutrophication is most commonly seen in coastal regions and major steps have been taken recently to try and combat the growing problem. Sources: www.epa.gov http://www.ehow.com/ab

Sea due to high evaporation and damaged aquatic life near the Great Barrier Reef caused by run-off from agricultural land. Eutrophication is caused by an excess amount of nitrate and phosphate in water bodies. It is usually caused by fertiliser run off and dumping of sewage going into waterways (basically human activity). Algal bloom is the direct result of eutrophication where suffocation of aquatic life and nutrient depletion may occur. Professionals may use a colorimetric analysis to measure
