Water Purification Tablets

[harrypalmer]

Just take the required amount of tabs, its doubtful you will 'build up your immune system'...use the tabs. You only need to be on your own, get a bad dose of "Gandhi's revenge" and you could be dead in 72 hours or less. Have you ever seen somebody die because their body simply can't retain fluid? I have and its not nice.

Use something like a Millbank bag to pre-filter water if its turbid, then use the tabs or better still pre filter, run it through something like a Sawyer mini filter and add tabs (in case of viruses being present). Pre-filter, mini filter then heat the water to 70c to kill of any remaining viruses is another route.

Never, ever, take chances with your water supply.
