Cryptosporidium is a chlorine-resistant protozoan that has been the plague of the water treatment industry for decades.
Part of an extremely hardy family of protozoa, cryptosporidium has the ability to form a hardened exterior, or cyst, around its cells, making it resistant to the disinfecting powers of chlorine.
While it does not normally occur in drinking water, municipal water treatment facilities have no way to remove it from water when it does contaminate.
Ingestion of cryptosporidium generally results in gastrointestinal illness.
Breakdowns in the city's purification system can result outbreaks such as Walkerton, where 6 died and 2500 were very sick, (some will never recover), North Battleford, Charlottetown, St. John's, Cranbrook, Kelowna, Sioux Lookout and Milwaukee where 100 died and 400,000 were sick.
A kitchen purifier is the only way to guaranty safety for you and your family.
