Most local tap water can be purified by boiling it for 2 minutes. There are also small tablets that you can buy to put in water you may have collected in a plastic container at camping stores for when all you have is lake water.
1. Boiling (but not effective in high altitude): Kills most bacteria and viruses.
2. Filtration using chemical additives like chlorine, iodine, chlorine dioxide, etc, unfortunately not great taste
3. UV light (between 240 nm and 290 nm), prevents microbes from reproducing)
4.SODIS -Solar Disinfectant- water placed in clear container in sun for 6 hours, oxygenized by shaking. Radiation/temperature kill microbes
5. solar still…similar mechanisms but slightly different design
Also purification depends on what needs to be purified from the water in terms of microbial organism and trace elements
Unless you are in an area where you know the water to be unsafe, or you have a medical condition that makes your doctor tell you not to drink tap water, there is no reason to ‘purify’ it. In every western country, public water supplies are treated to make them safe for human consumption. Bottled water is no ‘purer’ than the tap water in any American or European city.
Someone said to put a tablespoon of bleach per gallon of water, that would be unsafe to drink, but fine to use to clean counters.
In an emergency if you need to purify water for drinking purposes use ONLY two drops of chlorine bleach (Clorox is best as far as taste goes).
Otherwise boiling it as others have said will work too.

I read this in a leaflet about disasters.
