- Debris is visible to the naked human eye within a water sample. Some common examples of debris include: dirt, sand, plant or vegetative matter, pieces of plastic, glass fragments, metal shavings, rocks and animal/human waste. Large screen filtering should take care of this rather easily and as I said before, it’s not something normally needed to be dealt with from “treated water” from a municipality.
- Toxic elements, chemicals and metals are still present in your everyday water supplied to you in an urban setting. While your municipal water treatment facility remove much of these harmful things from your tap water; they will still leave some amount of them in it based on Federal regulations and standards and their own guidelines based on a certain amount of PPM. Of course, this does not account for whatever gets back into your water supply from the water delivery system in your home (e.g., pipes). You can buy and use water filters from the store to remove a much greater percentage (PPM) of this from your drinking water.
- Living organisms like bacteria, protozoa, cysts and viruses can also be delivered to you in your municipal water supply. Many store bought water filters will remove these from your drinking water based on the filter’s pore size. A pore size is the size of the “holes” in the filter that can get through into your drinking water. The pore size of most water filters is measured in “microns” or fractions of a “micron”. You need to use the smallest pore size possible to filter out most of these living organisms. However, you will NEVER filter out all of them so in survival mode it is ALWAYS recommended to do something to kill these microorganisms. You can kill the microorganisms in several ways. Heat: Boiling the water for 5-10 minutes will usually kill off just about anything living in the water. Chemical treatments or Water purification tablets added to water will also kill off the microorganisms usually within several hours (although it might make the water taste “funny”). Ultraviolet (UV) lighting when inserted into the water container will also kill off the microorganisms (timeframe will depend on the quantity of water, size/power of the UV light and the amount of living organisms).
Survival is a combination of preparedness plus a survival mindset. If you have the WILL to survive, the skills/knowledge to survive, as well as, some planning and preparation ▬ then you will ultimately survive. Don't wait until it is too late or your chances for survival will diminish accordingly. As always, good luck and know I am on your side. ~~ The Survival Guy
