Hello Sam. I truly appreciate your post because it put in the proper perspective how valuable clean water is. Ohio also has a similar issue with its clean water as well. Although pollution from local industries are not the main cause of unclean water in our aquifers, relaxed enforcement of Safe Drinking Water Act stifles progress. In the past few years, Ohio has been in the top 10 states for most offenses against these laws. Although they consistently violate these health standards, not much is being done to enforce standards to protect the population that the water systems are serving. As you have pointed out, when something is not done to control the waste or any other significant health concern, more damage will be done. Great post!

I believe clean water will one day be more valuable than oil. Both will eventually run out but water is needed so much more as more people are moving to the urban areas. People don't have to rely on oil as much if they are riding their bikes to work or taking the rail system. I think people use water in their everyday lives so much more. People use clean water to clean themselves like taking showers or baths. People also use clean water to drink, to wash their clothes, to grow agriculture, and to cook. Oil is mainly only used for transportation, whether it's flying or driving the car somewhere.

There are a bunch of treats to clean water in the world. One of these threats is agriculture. Fertilizers that farmers use are toxic and seep into the ground and eventually into groundwater. This contaminates the ground water being used for drinking by communities in the area. Another threat that also affects clean water and drinking water is the production of fossil fuels. The use of fracking and coal mining can contaminate groundwater as well. Out here in Wyoming, a lot of fracking goes on. Scientist found highly contaminated water after a fracking operation in Wyoming. In their underground water supply,  levels of benzine was were found in the water that were 50 times to allowable amount. Benzine is the flammable liquid found in fuel. My local water source comes from the mountain streams of the Medicine Bow forests and Laramie mountain range and the other thirty percent comes from groundwater and wells. Some of the possible contaminants around my area could be from the fertilizers the farmers put into their crops or from all the fracking that goes on here.

Sam,

I initially felt the same way about new oil being discovered.  I thought that it would naturally cause the reduction of oil prices.  The I thought, wouldn't it depend on who discovered the oil?  I know that the middle East and Russia have large amounts of oil supply.  I don't beleive that the current price of oil is dependant on the amount of oil they have as much as it is dependant on how much OPEC allows to be injuected into the market and what those countries allow.  If the United States discovered the oil, this would help oil prices here.  I beleive it all depends on who controls the new discovery more than anything.

For my two examples I have chosen the Alaskan pipeline being completed and a new, very large deposit of oil being discovered in some unnamed country.  In both events I believe the price of oil would decrease because there would be more product readily available for America's due to the close proximity of oil being in Alaska.  It would cause our need to import oil from other countries to decrease.  The large deposit would do the same also because yet again the supply for oil would increase causing a decrease in price.
