Waterborne infections
While reading through a government report on waterborne infections, something interesting came out. Cryptosporidium accounted for about 65% of all waterborne infections.
Here is the breakdown:
Cryptosporidium accounted for 65%
E. Coli accounted for 6.3%
Campylobacter 6.1%
Giardia 2.1%
Shigella Sonnei – 8.5%
Norovirus – 8.3%
Now lets combine that with some more information.
Here is another US Government report on Microorganism size and susceptibility to filtration report.
| Organism | Average sizes |
| Viruses | 0.03 |
| Enteric bacteria (E. coli) | 0.5 × 3.0–8.0 |
| Cryptosporidium oocyst | 4–6 |
| Giardia cyst | 6.0–10.0 × 8.0–15.0 |
When I’am concerned about the water that I’am filtering, I try to take the area that I’am in, into consideration.
Is the water down stream from a rural or heavily populated area?
Has there been any recent flooding in the area? The flooding goes hand in hand with populated areas. If the sewage lines or septic tanks were recently flooded, then the risk of contaminated water increases.
If the water from a running stream, or a pond / pool of water?
If you have any questions, post them in this forum thread about Water Filtration.
