If your water source is uncertain, you should treat it first before drinking it.
One way to treat water for drinking is to add a small amount of regular bleach (chlorine). Here’s how much bleach to add, and a way to remember the quantity:
When obtaining water to be purified for drinking, avoid (if possible) water which is cloudy. Perhaps there is another nearby access to the same body of water which may be clear.
If scooping water from a pond, etc., try not to disturb the bottom so as not to disturb and pick up dirt or other debris into your water container.
If the water appears cloudy, if possible filter it before treatment. Use a conventional water filter, or any cloth or such filtering material to catch the floating particles as you pour from one water vessel to another. If you cannot pre-filter a cloudy water source, let it settle in a container for a time, and then gently pour off or scoop the water near the top which will be clearer. This is important because the floating ‘dirt’ particles within the water are tougher (takes longer) to penetrate while purifying with chlorine (bleach).
