Reply:Boiling the water should help, how ever, it depends on the bacteria, cause if its a "bad" bacteria one should first make test on it, like send it to a lab or something
Reply:I suggest, first to filter the while, then boil the water. I go backpacking every month into the woods and mountains. To get fresh drinking water, we always filter it, using a filter, and then we boil the water. the boiling will kill off all the bateria that where able to get through the filter. Hope that helps.

Reply:Boiling - most bacteria will be killed by the temperature








osmosis is the movement of water through membranes which by altering, you won't kill many water-borne bacteria





settling won't stop the bacteria from swimming around, many are motile





filtering will only do it if you use a micropore filter (2-4um pores)
