This video was posted as a response to a question off the website. The question was about getting water to somewhere there is no city water.
Be careful drinking water from creeks and streams. If people live up stream there is the chance of polio, cholera and typhoid being in the water.
If life stock are up stream, such as cattle or horses, then the water could contain cryptosporidium.
Some people say that polio has been removed from the USA, but cases still occur - though very rare, polio is still out there.
