Caption to picture: This is the current and typical irrigation system for farms and larger areas of land.
SUMMARY: As of today the EPA confirmed that they had created an irigation system that would allow any commercial or private residence to save about 410 million dollars a year on irigation and water bills. Shelia Frace the EPA director said, "As much as half of the water we use on our landscapes goes to waste..." Not only will this help save money but it will save water because upwards of 7 billion gallons of water are used for landscaping reasons. This system is WaterSense approved, and will be available for purchase by Spring 2012. It is so far the only system that is WaterSense approved and EPA approved.
OPNION: My opinion of this system is that it will save a lot of water for everyone and it will also help cut back on money spent. I also find it shocking how much water we waste on watering our lawn basically, I mean I can understand doing this when you have a garden that you can get food from. But when you are just watering grass it seems really wasteful. Finally I think that it is really good that the EPA is making it known that we are wasting water, like we learned Gandhi said, "There is enough water for human need, but not enough for human greed."
QUESTIONS:
1) Do you think that watering you lawn is wasteful or a requirement?
2) What would you do if we ran out of water because it had all been used?
3) About how many gallons of water does you family use on landscaping?
4) Are there any other WaterSense Appliances?

Arsenic in Drinking Water

Picture: This picture shows the consentration of Arsenic in the United States. (I have included the link to the picture because the words are hard to see.)
Summary: Arsenic is an element on the periodic table that is oderless and colorless. It is harmful to humans and animals if ingested. It comes from natural deposits in the earth or from agriculture and industries. Arsenic has many non-cancer effects such as, thickening and discoloration of the skin, stomach pain, nausea, vomiting, diarrhea, numbness in hands and feet, partial paralysis, and blindness. It also is known to cause cancer of the bladder, lungs, skin, kidney, nasal passages, liver, and prostate. The EPA (Environmental Protection Agency) has set a standard of .010 parts per million (ppm) (10 parts per billion; ppb) for drinking water. Many villages in Africa had water that contained high volumes of Arsenic and many were dying and no body knew why. Eventually scientist found the Arsenic in the water and had to find a way to get it out so people would stop dying of the symptoms listed above. In 2009 IRIN ( ) tested water from 360 wells and they were all contaminated with arsenic.
Opinion: I think that the amount of aresenic in the water in Africa is very alarming and unsettling. To think that all of those children are drinking water that they have no idea is actually killing them. Its so sad to think about. This article is directly related to the discussion we had in class. We also learned that ilters were sent out by an organization called Filters for Familes to filter out most of the arsenic so that fewer people would die of arsenic poisoning.
Questions:
1. Is there any other place in the world that has a worse Arsenic concentration level than Africa?
2. Was there ever a time in history that the U.S. had high levels of Arsenic?
3. What would you do if you found out htere was a high level of Arsenic in the water around your town?
