Pollution

Water pollution is the problem.

This site has very good information on how water pollution happens 1. Krantz, D & Kifferstein, B. (1997). Water Pollution And Society. Retrieved December 9, 2009 from [|http://www.umich.edu/~gs265/society/waterpollution.htm]

This site tells you about how we are slowly but surely harming our planet earth! Many types of rare fish are dying in the water and we need those fish to live. Petroleum also pollutes bodies of water but its not often. The major sources of water pollution are municipal, industrial, and agricultural. 95% of all fresh water on earth is ground water. In 1970, the Clean Water Act provided 50 billion dollars to cities and states to build wastewater facilities. With over 70% of the planet is covered by oceans, people have long acted as if these very bodies of water could serve as limitless dumping ground for wastes.

This site tells about how pollution can effect people. If people drink polluted water, they can have serious effects. Viruses and bacteria can get in the water. Water pollution causes fish to die, even some people can die from drinking it. Water can also be polluted by plastics, oil and other things like that. Water pollution usually comes from us humans. We detect water pollution by taking a small sample of the water and test it in labs. They also use computer models to determine what dangers there can be in certain waters. Eutrophication is mainly caused by an increase in nitrate and phosphate levels and has a bad influence on water life. This is because, due to the enrichment, water plants such as algae will grow extensively. As a result the water will absorb less light and certain aerobic bacteria will become more active. This makes it hard for organisms to live in the water. Water still sometimes smell like rotten eggs because bacteria make gases during their activities.

This has a lot of good information 3. Wheeler, T. (2009). The Baltimore Sun. Retrieved December 9, 2009 from []

This site is about chemicals that are put on farms and lawns that kill fish. Somehow it is getting into the Potomac River and killing all the fish. Abnormal fish have turned up in the river's South Branch and in the Shenandoah River. Up to 80% of sampled fish have intersex conditions, and endocrine-disrupting chemicals. Water treatment facilities are not yet required to screen for endocrine disrupting contaminants, so they end up in our tap water. Go to this website to find out what it is.
