Chlorine Resistant Parasites and Bacteria Discovered In Municipal Tap Water

We like to think of parasites as something belonging to 3rd world countries. That’s the furthest thing from the truth.


There are thousands of LIVING ORGANISMS infesting municipal tap water. This includes viruses and bacteria! Bacteria like Legionella, Shigella, and Cryptosporidium are responsible for MASSIVE amounts of water contamination across the United States.



Our water may also contain parasites – small, microscopic organisms, but their impact is ANYTHING BUT microscopic! They can cause severe and sudden illness, diarrhea, vomiting, abdominal pain and cramping, dehydration, weight loss, fever, and can even be fatal in some cases!


In 2018, the use of tap water in a nasal-flushing Neti pot likely led to a Seattle woman's death from a brain-eating amoeba, doctors write in a case study. Instead of using sterile water or saline, it's believed the 69-year-old woman used tap water she'd put in a filter-equipped pitcher, CBS News reported. The amoeba got into her upper nasal cavity and then into her bloodstream, eventually reaching her brain, according to the study in the International Journal of Infectious Diseases.


Cryptosporidium is a microscopic parasite that has become recognized as one of the most common causes of waterborne disease in humans. This microscopic parasite is resistant to chlorine AND is hard to filter out ─ so outbreaks of cryptosporidiosis are hard to prevent.

Getting rid of it from your body isn’t as simple as a trip to your doctor for antibiotics. There are currently NO MEDICINES available that can conquer it.


Bottom line, you don’t want to let these little guys into your body in the first place. The most effective way to ensure this happens is to use a water purification system, such a reverse osmosis, that is certified to filter out parasites and bacterial.
