E. coli is a bacteria whose harmless strains are commonly found in the intestines of humans. A particular E. coli strain, called the 0157:H7 strain, found in contaminated well or surface waters, can cause severe illness such as bloody diarrhea or even kidney failure, especially at risk being young children and the elderly. The Walkerton tragedy in May 2000 was caused by the outbreak of E. coli into the drinking water supply.

Rainfresh Drinking Water System 1, 2 and 3 use Rainfresh’s proprietary ceramic filter cartridges that have been independently tested and verified for reduction of E. coli. In addition, they have also been tested for reduction of other bacteria that cause water-borne illnesses such as cholera, dysentery, typhoid etc.

A cyst is a resting stage of a parasite that helps it tide over unfavourable environmental conditions. When the parasite reaches favourable conditions (such as the human intestine), the cyst wall breaks and the microbe causes illness. Commonly known cysts are Giardia Lamblia and Cryptosporidium. They are present in stagnant waters such as dug wells, lakes, ponds and other surface waters. Cysts cause illnesses such as Giardiasis (commonly called Beaver Fever), stomach cramps, fever, diarrhea, etc.

Cysts are resistant to chlorination, the most common disinfection method used by municipalities. As such, it is possible to have cyst contamination even in chlorinated (municipally treated) water supplies. Physical removal of cysts from water by filtration is the most effective way of preventing illnesses from cyst. Rainfresh Drinking Water system 1, 2 and 3 are tested and certified for reduction of cyst from water.

Trihalomethanes (THM ) – CHEMICALS

THM are chemical compounds formed by the reaction of disinfectants such as chlorine , with natural organic compounds (decaying leaves & vegetation). Many THM were also used over the years as solvents and refrigerants and now sometimes find their way into our drinking water supplies. THMs most commonly found in drinking water are chloroform, bromodichloromethane (BDCM), dibromochloromethane (DBCM) and bromoform, although over 50 are known to be present in various drinking water supplies.

THM are considered possible carcinogens (cancer-causing) in humans. According to Health Canada, animal studies indicate a link between specific THM and tumours. Some human studies also link THM with colorectal cancers & reproductive problems.

Rainfresh Drinking Water System models UCS3, QS1, QS2 and filter cartridge models LR1 & VC1 are tested and certified for reduction of THM from water.
