28. Eutrophication is an enrichment of the ocean with chemical nutrients mostly containing nitrogen and phosphorous. This has many effects on the environment—plant growth will be maximized and they might grow large enough to take over the ecosystem. It results in the depletion of oxygen from water and deteoriating conditions for organisms--hypoxic “dead zone” areas. Eutrophication tends to occur in more low-lying agricultural areas, such as the Mississippi River Delta. The right amount of nutrients can be good for an ecosystem, but too much causes nutrient pollution of water bodies. Toxic algae blooms form and restrict the use of water by organisms, leading fish to consume the dissolved oxygen and be suffocated and killed. 27. Water pollution is the release of waste products to surface runoff into groundwater, liquid spills, eutrophication and littering. According to the EPA’s drinking water contaminants list, just a few of the contaminants allowed in larger portions are nitrate (from fertilizer use and sewage),
