Water purification
Sadly gone are the days where you could drink straight from most streams and not have much to worry about, todays streams, ponds and rivers are often contaminated with waterborne pathogens, viruses, bacteria, chemicals and heavy metals the majority of which cant be seen with the naked eye.
This leads us to the subject of water purification there are a few ways to do this, chemically, filtering, boiling and evaporation the following articles will cover these methods!

Chemical and filtration
The most popular form of water filters use chemical or filters to purify water and sometimes both.
chemical works by killing bacteria, viruses and waterborne pathogens making the water safer to drink it often does this by using various chemicals iodine being the most popular.
Filters work by letting the water through a certain type of membrane but not the bacteria they also filter chemicals and heavy metals however, some only filter certain types of things not others so its best to check with the manufacturer.
A few things to consider chemicals can give water a bad taste and don't filter the water at all filters may leave a bad taste and may not filter all of the unwanted things mentioned however with a good filter it may do all things necessary including removing bad taste!

Boiling
The most basic method of purification yet in a perfect world it should be the only one needed.
Boiling kills waterborne pathogens and viruses however, it will not filter debris and certainly will not remove chemicals for example fertilisers and pesticides neither will it filter other dangers such as heavy metals and feces. If you can find a source thats out of the way of city life and agriculture you'll probably be fine.
