Transcript of Water pollution

The problem Water Pollution Water Pollution There is a large water pollution problem in the world. We are trying to see what people can do to help. We also want to educate people about this worldwide problem. Introduction: Our group is doing our project on water pollution. Our names are Riley, Megan, Liam, and Mitchell. We are all in the fifth grade. This year we are required to find a problem in the world and inform many people about this problem and attempt to solve it. In this presentation we will tell you the issue, describe the issue, tell you the importance of this issue, how to help, and we will give you a page for sources so you can check out some of the websites. We hope you learn a lot and enjoy the presentation! Description of the Issue Everyone who throws a piece of trash in a lake, river, stream or Ocean is involved but every one who donates is also involved in this world wide emergency. You can help by using cloth bags' metal water bottles in stead of bottled water and use recycled plastic. You can help by Using metal water bottles in stead of bottled water and recycle.

Here is what The Water project says to do
1. Start a fundraiser
2. Get your school involved
3. Join My Water Project
4. Spread the word. The Water Project is helping in Africa by digging wells.In Africa the types are hand dug They're about 50` deep and very dangerous they are the famous hole and a bucket with a roof image but can be easily contaminated, then the shallow machine dug ones that use a pump to extract the water and can be 200`deep, and very deep wells that need industrial digging machines they can cost 30,000$ be 900`deep and serve 3,000 people. People all over the world do not have axis to clean water. Some bodies of water are human contaminated like Citarum River in West Java, Indonesia, and some are naturally contaminated like the green algae filled Chaonu Lake in Anhui, Provine China. One way the Water Project helps is digging wells in Africa. There are three main types of wells. The first one is a hand dug well and it is very dangerous. They are extremely dangerous to build because they are about 50 feet deep and people can fall in, but they are used where there is a lot of ground water. They get polluted easily.

Then there's a shallow well which is 50-200 feet. The Water Project uses small rigs, provided by donors, to build them. They are very cost effective in Kenya and can be moved with ease. It allows work to be done quickly and gives very clean water. As the machines drill through the rock, casing is installed to keep the well from falling in. A concrete base is formed around the small casing and it is left to set overnight. Once the concrete is dry a small hand pump is put in and sealed so it can't get polluted.
